Abstract
The invention discloses a flow channel for a mould, comprising a finished product parting inclined surface inlet, and a glue inlet device. The flow channel for a mould is characterized in that the finished product parting inclined surface inlet and the glue inlet device are arranged in a linear direction; the glue inlet device is a hot glue channel; and the flow channel for a mould is designed to be integral-ring-shaped. The flow channel for the mould provided by the invention is simple in structure and convenient to use; and the finished product parting inclined surface inlet and the glue inlet device are arranged in a linear direction, which is very important for a whole injection moulding production process, and improves the quality of products.
Description
Technical field
The present invention relates to a kind of mold runner.
Background technology
The mold cavity surface is heated to the heat distortion temperature of plastics, injected plastic then, in the injection moulding process, the temperature of mould remains unchanged, and the temperature of the back mould that finishes drops to the taking-up product gradually, and next injection treatment starts, and die surface heats rapidly.Mold temperature raises and reduces all very fast.
Mainly be to mould.Offer even distribution water route in mould die and the outward appearance slide block, utilize high-temperature high-pressure steam to be the Fast Heating medium, chilled water is the cooling medium; Use air tracheae air pressure again, see through RHCM (high-speed and high-temperature forming technique), in plastics, add glass fibre; Produce the shell with reflecting effect, RHCM can solve product problems such as the insoluble joint line of common moulding, current mark, and equipment switches in the water route in die and sliding field; Heating, cooling die.
Before the injection in die and the slide block in the water route with the high-temperature high-pressure steam rapidly heating moulds to higher temperature (120 spend).
Utilize steam to keep temperature in the injection.
Stop to supply with steam in the water route in intact die of injection and the slide block, blow clean residual aqueous vapor in the water route, change logical chilled water again and carry out the mould fast cooling with air duct air pressure.
Drop to proper temperature, eject die sinking after the product cooling and get into second circulation.RHCM equipment is equivalent to be exactly one can heat fast, fast cooling die.
The design of mold runner is directly connected to into glue, influences the quality of final products.Particularly run into when the finished product die joint is oblique pulls out, be easy to cause the product shaping quality because of the design of mold runner.As shown in Figure 1, when the problems referred to above will appear in the direction of advancing a little to advance glue direction and finished product face.
Summary of the invention
Purpose: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of simple in structure, easy to use, mold runner that efficient is high.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is: mold runner comprises: finished product somatotype inclined-plane enters the mouth and advances adhesive dispenser, it is characterized in that: said finished product somatotype inclined-plane enters the mouth and advances linearly direction setting of adhesive dispenser.
Saidly advance mucilage binding and be changed to the hot glue road.
Said mold runner is designed to whole circle type.Disperse everywhere after can avoiding runner to eject like this.
Beneficial effect: mold runner provided by the invention, simple in structure, easy to use, through entering the mouth finished product somatotype inclined-plane and advancing linearly direction setting of adhesive dispenser; Extremely important for whole injection moulding production process, improved the quality of product.
Description of drawings
Fig. 1 is the prior art constructions sketch map;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As shown in Figure 2, mold runner comprises: finished product somatotype inclined-plane inlet 1 with advance adhesive dispenser 2, said finished product somatotype inclined-plane inlet 1 with advance linearly direction setting of adhesive dispenser 2; Saidly advance adhesive dispenser 2 and be the hot glue road; Said mold runner is designed to whole circle type.The (not shown) of dispersing everywhere after can avoiding runner to eject like this.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within protection scope of the present invention.
Claims (3)
1. mold runner comprises: finished product somatotype inclined-plane inlet and advance adhesive dispenser is characterized in that: said finished product somatotype inclined-plane inlet and advance linearly direction setting of adhesive dispenser.
2. mold runner according to claim 1 is characterized in that: saidly advance mucilage binding and be changed to the hot glue road.
3. mold runner according to claim 1 and 2 is characterized in that: said mold runner is designed to whole circle type.
