The utility model discloses a set up the amphitypy groove and in order can form the amphitypy chamber behind the compound die, make a mould be equipped with the amphitypy chamber on the half module, during blowing, can once only process out two oil tanks, improved production efficiency greatly, two oil tanks of simultaneous processing are compared and are only processed an oil tank alone, have reduced the production of overlap material, have reduced the processing cost, in addition, through setting space holding blocks, can guarantee under the circumstances of the relative mould of oil tank slope the inner wall contact of oil tank and blowing mould.
Description
Technical field
The utility model is related to produce the mould applications of fuel tank, more particularly to a kind of fuel tank blow moulding tool of double cavity structure.
Background technology
With the birth and the development of blow molding machine of high density polyethylene (HDPE), blow molding technology is widely applied.Extrusion
Blowing is a kind of method of manufacture hollow thermoplastic's product, and thermoplastic resin is extruded to be molded the plastic parison for obtaining, while hot (or
Be heated to soft state), in being placed in split cavity, in parison compressed air is passed through immediately after mold closing, make plastic parison inflation and
It is close on mould inner wall, Jing cooling and demoldings obtain various hollow products.
At present, for auto manufacturing, fuel tank is obtained by being blow molded processing.The structure of the mould of existing blowing fuel tank
For a cavity per mould, each blow moulding cycle can only produce a product, and for the fuel tank of small volume, (Jing is cold to produce larger overlap
But after, crushing, it is only capable of being used as reclaimed materials), high energy consumption, efficiency is low, and raw material input is big, and product cost accordingly increases.
In view of above-mentioned defect, the design people, positive research and innovation in addition, to founding a kind of fuel tank of double cavity structure
Blow mold so as to more the value in industry.
Utility model content
To solve above-mentioned technical problem, the purpose of this utility model is to provide one kind can improve production efficiency, reduction exploitation
The fuel tank blow moulding of cost and the double cavity structure that can once go out two fuel tanks has.
The fuel tank blow moulding tool of double cavity structure of the present utility model, including the half module of two die cavities, institute can be formed after matched moulds
Half module is stated including template, the template is provided with the type groove and the two aperture blowing grooves for connecting with two type grooves respectively of two accommodating parisons,
Aperture blowing groove corresponding after two-half die matched moulds can form aperture blowing, and the plane of the relatively described template in edge of type groove described in two is convex
Rise；The spacing maintainance block of multiple projections is provided with the plane of the template on the outside of type groove described in two.
Further, in the plane of the template with two Surveying ＆ Mapping Benchmark grooves, two Surveying ＆ Mapping Benchmarks are provided with described in two between type groove
Groove is respectively distributed on the relative both sides of the edge of the template.
Further, the template is provided with multiple pin-and-holes.
Further, on the relative edge of the template two, some locating slots are provided inwardly with along its edge.
By such scheme, the utility model at least has advantages below：
1st, by the way that two type grooves are arranged on half module so that two die cavities can be formed after matched moulds, make a mould for two die cavities, blow
During modeling, two fuel tanks can be disposably processed, substantially increase production efficiency；
2nd, while two fuel tanks of processing compare only individually one fuel tank of processing, the generation of overlap material is reduced, reduces and add
Work cost；
3rd, by setting space maintainance block, it can be ensured that in the inclined situation lower fuel tank of fuel tank opposing mold and blow mold
Inwall is contacted.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Description of the drawings
Fig. 1 is the structural representation of half module of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
Referring to Fig. 1, a kind of fuel tank blow moulding of the double cavity structure described in the preferred embodiment of the utility model one has, including conjunction
The half module of two die cavities can be formed after mould, half module includes template 10, and template 10 is provided with the type groove 11 and two of two accommodating parisons
The aperture blowing groove 12 for connecting with two type grooves 11 respectively, aperture blowing groove 12 corresponding after two-half die matched moulds can form aperture blowing, two type grooves
The planar projections of the 11 equal opposite formwork 10 in edge；It is provided between multiple projections in the outside of two type grooves 11 in the plane of template 10
Away from maintainance block 13.
The utility model makes a mould for two by the way that two type grooves are arranged on half module can form two die cavities after matched moulds
Die cavity, during blowing, can disposably process two fuel tanks, substantially increase production efficiency；Simultaneously two fuel tanks of processing are compared only
Individually one fuel tank of processing, reduces the generation of overlap material, reduces processing cost；In addition, by setting space maintainance block, can
Guarantee to be contacted with the inwall of blow mold in the inclined situation lower fuel tank of fuel tank opposing mold.
For convenience of benchmark mapping is carried out to half module, the utility model is provided with the plane of template 10 between two type grooves 11
Two Surveying ＆ Mapping Benchmark grooves 14, two Surveying ＆ Mapping Benchmark grooves 14 are respectively distributed on the relative both sides of the edge of template 10.
Mould is formed after to make two-half die matched moulds, and prevents the relative slip of two-half die, the utility model from setting in template 10
There are multiple pin-and-holes 15, two-half die is connected by pin.
For convenience of blow mold of the present utility model is precisely mounted on blow moulding machine, the utility model is in 10 liang of template
On relative edge, some locating slots 16 are provided inwardly with along its edge, blow mold location and installation is existed by each locating slot 16
On blow moulding machine.
Operation principle of the present utility model is as follows：
First two-half die matched moulds is formed into blow mold, blow mold is installed on blow moulding machine, blow gas are imported
In the preform processed to Jing thermal conditionings, while preform is maintained in the blow mold of blow moulding machine, pre- blow mold stage,
Blow gas are imported in preform so that the close blow mold of material of the conditioned process of preform
Wall；In subsequent last blow mold stage, blow gas are imported in preform so that preform it is conditioned
The type that the material of process is squeezed into the blow molding mould wall is wide, so as to once be blow molded out two fuel tanks.It is controllable during extrusion-blown modling
Parison length processed, to increase stock utilization, reduces overlap.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, it is noted that
For those skilled in the art, on the premise of without departing from the utility model know-why, can also do
Go out some improvement and modification, these are improved and modification also should be regarded as protection domain of the present utility model.
