Description
Technical field
The present invention relates to connecting pipe technical field of mold, more particularly, to a kind of injection mold of pipe fitting.
Background technology
With the improvement of people's living standards, the also continuous hommization of residence technology level, in order to save the area, skyscraper
It is more and more, especially noise can be generated using plastic tube in toilet.Traditional traditional 45 ° are tiltedly direct-connected to be taken over as two pieces master
Body, connecting tube is divided into two parts using two molds and is molded by mold during injection molding, on the one hand since connecting tube needs
Matching connection, thus it is also higher to the required precision of two parts pipe fitting mold, and Split injection increases production cost, the opposing party
Face, the oblique straight tube both ends of split are formed by connecting with bonding way, and manually bonding can cause to be bonded uneven, leave hidden leakage defect,
And generate drainage.
Invention content
The technical problems to be solved by the invention are：Tiltedly direct-connected production is taken in order to overcome for split type 45 ° in the prior art
Of high cost and artificial bonding is there are the deficiency of hidden leakage defect, and the present invention provides a kind of injection mold of pipe fitting, using injection
It is integrally formed, the oblique straight tube that original split is bonded is improved to the oblique bend pipe with small circular arc type structure, is saved so as to reach
Cost avoids the effect of leakage.
The present invention solves its technical problem technical solution to be taken：A kind of injection mold of pipe fitting, including upper
Mould, lower die and mandrel component form the cavity with the pipe fitting form fit, the core group between the upper die and lower die
Part includes the first jacket, first time fuse, the second jacket, second time fuse and curved plug, first jacket and first time core
It is sub up and down to just, described curved plug one end have with matched first concave panel of first time fuse outer wall, under described first
Fuse is leaned against in first concave panel, and second jacket is set in the curved plug other end, second time fuse position
In the lower section of second jacket, and the top of second time fuse is equipped with recessed with the curved plug arcuate surface matched second
Shape face, second jacket and second time fuse dock, and curved plug is leaned against in second concave panel, the curved plug up and down
The pipe that virtual extended end for arc structure, and the curved plug along the circular arc direction of the arc structure is formed from the second jacket
It is pierced by the endoporus of connector.Virtual extended end refers to the extended end assumed for sake of clarity structure, in practical structures not
There are the extended end, first jacket, first time fuse, the second jacket, second time fuse and curved plug are spliced to form and manage
The matched shape of coupler bore.
Further, in order to ensure the relative position of the second jacket and curved plug and second time fuse, the curved plug and the
Two times fuses are equipped with and the matched concave-convex position limiting structure in the second jacket bottom surface.It is limited by concave-convex position limiting structure,
Avoid axial rotation.
Further, for the ease of the back-out of curved plug, the curved plug includes the arc sections and direct-column portion of integrally connected, institute
The outer diameter for stating direct-column portion is less than the outer diameter of the arc sections.The outer diameter of direct-column portion is less than the outer diameter of arc sections, on the one hand makes back-out
When direct-column portion and pipe fitting inner wall reduce interfere, convenient for quickly screwing out, when on the other hand being screwed out convenient for curved plug outside clamping
The clamping of tool, straight sections stretch out the second jacket.
Upper die and lower die are opened first in mold, then by the first jacket and the second jacket from injection connector
Top is taken out, and then extracts first time fuse and second time fuse from the lower part of injection connector out, finally by curved plug from setting
It is spun out in the endoporus for having the pipe fitting of the second jacket, completes the die sinking of pipe fitting.
The beneficial effects of the invention are as follows：A kind of injection mold of pipe fitting provided by the invention, providing a mold should
New approaches, by the setting of curved plug, plug is taken out by the way of rotation, makes to give birth to using integrally formed pipe fitting
Production has possibility, reduces the production cost of pipe fitting, improves production efficiency, in addition, being carried by using injection mold
The high leakproofness of pipe fitting.

Specific embodiment
Presently in connection with attached drawing, the present invention is described in detail.This figure is simplified schematic diagram, is only illustrated in a schematic way
The basic structure of the present invention, therefore it only shows composition related to the present invention.
The mode of original oblique straight tube can not be produced directly by the way of integrally formed, as shown in Figure 1, by
Plug is inserted into inside pipe when injection, if oblique straight tube, needs to prolong along the straight line of pipe when taking out the plug in oblique straight tube
It stretches direction and is pulled outwardly plug, since extending direction by the blocking of supervisor's tube wall can not be taken out plug, arrow represents plug
Pull-out direction, dotted line represent the extending direction of oblique straight tube.
The mold of this patent uses curved plug 5, and the pull-out of straight line is converted into the rotation in circular arc direction, passes through the side of rotation
Formula takes out plug.
As shown in Figures 2 and 3, the injection mold of a kind of pipe fitting of the invention, including upper die and lower die and mandrel component

Lower fuse 2, the second jacket 3, second time fuse 4 and curved plug 5, first jacket 1 and first time fuse about 2 to just, institute
State curved 5 one end of plug have with the matched first concave panel 5-1 of first time fuse, 2 outer wall, first time fuse 2 lean against
In the first concave panel 5-1, second jacket 3 is set in 5 other end of curved plug, and second time fuse 4 is located at
The lower section of second jacket 3, and the top of second time fuse 4 is equipped with and curved 5 arcuate surface of plug matched second
Concave panel 4-1, second jacket 3 and second time fuse dock about 4, and curved plug 5 leans against the second concave panel 4-1
It is interior, the curved plug 5 be arc structure, and the curved plug 5 along the circular arc direction of the arc structure virtual extended end 6 from
It is pierced by the endoporus for the pipe fitting 200 that second jacket 3 is formed.Virtual extended end 6 refers to assume for sake of clarity structure
Extended end, in practical structures and there is no the extended end, under first jacket 1, first time fuse 2, the second jacket 3, second
Fuse 4 and curved plug 5 be spliced to form with the matched shape of 200 endoporus of pipe fitting, in order to ensure the second jacket 3 and curved plug 5 and
The relative position of second time fuse 4, the curved plug 5 and second time fuse 4 are equipped with matched with 3 bottom surface of the second jacket
Concave-convex position limiting structure 7, arc sections 5-2 and direct-column portion 5-3, the direct-column portion 5-3 of the curved plug 5 including integrally connected is outer
Diameter is less than the outer diameter of the arc sections 5-2.
As shown in figure 4, during die sinking, upper die and lower die are opened first, then by the first jacket 1 and the second jacket 3 from note
The top of modeling connector 200 is taken out, and then takes out first time fuse 2 and second time fuse 4 from the lower part of injection connector 200
Go out, finally spin out curved plug 5 from the endoporus of the pipe fitting 200 equipped with the second jacket 3, complete opening for pipe fitting 200
Mould, arrow represents the direction of motion of each structure of mold in figure.
As shown in figure 5, the pipe fitting 200 of mold injection molding using the present invention, including two standpipes 21 and is arranged on
Oblique bend pipe 22 between two standpipes 21, the oblique bend pipe 22 is arc-shaped structure, and described arc structure one end is along the circular arc
