Abstract
The utility model discloses a mould for producing automotive interior parts. The mould comprises a movable mould and a fixed mould, wherein an injection molding cavity is formed after the movable mould and the fixed mould are assembled; the mould is characterized in that the same inner wall of the injection molding cavity is provided with at least two convex blocks. According to the mould for producing the automotive interior parts, the convex blocks arranged on the inner wall of the injection molding cavity are respectively matched with through holes formed in a diaphragm, and the diaphragm is accurately located at the specified location on the inner wall of the cavity, so that the position accuracy of the diaphragm is improved, and the quality of an injection molding product is further improved.
Description
Technical field
The utility model relates to automotive upholstery production field, particularly a kind of mold for producing automotive upholstery.
Background technology
During automotive upholstery is produced, commonly use dummy slider injection moulding, the diaphragm of soon preparing by vacuum forming or high-pressure molding technology (as plastics sucking moulding) is put into the die cavity of injection mold, the technology of injection mo(u)lding on diaphragm, in the last few years, because of it, can decorate the advantages such as more complicated three-dimensional surface, technique environmental protection and be widely used, but also have following defect.Existing dummy slider injection moulding, diaphragm is generally adsorbed on the die cavity inwall of mould by vacuum extractor, but this kind of suction type is very unstable, when diaphragm is installed, because of without alignment device, occurrence positions deviation very easily, injection-molded item is deformed, cause defective goods rate to rise.On the other hand, in injection moulding process, due to without positioner, only, by the fixing diaphragm of pull of vacuum, can there is the problems such as diaphragm is wrinkling, diaphragm skew, further cause injection molding material to depart from diaphragm moulding, reduce yields.
Utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of mold for producing automotive upholstery with diaphragm positioning function is provided.
For realizing above object, the utility model is achieved through the following technical solutions:
Mold for producing automotive upholstery, comprises dynamic model and cover half, after described dynamic model and described cover half matched moulds, forms injection moulding die cavity, it is characterized in that, the same inwall of described injection moulding die cavity is provided with at least two projections.
Preferably, described projection is cylinder, Elliptic Cylinder, triangular prism or quadrangular.
Preferably, the number of described projection is two.
Preferably, also comprise diaphragm; Described diaphragm comprises diaphragm body; Described diaphragm body is provided with at least two locating pieces; Described locating piece is provided with through hole; Described projection inserts described through hole, and described diaphragm is arranged in described injection moulding die cavity and is arranged.
Preferably, also comprise vacuum extractor; Described vacuum extractor is communicated with described injection moulding die cavity, and the inwall Shangdi that described diaphragm is adsorbed on to described injection moulding die cavity arranges.
Preferably, described projection is arranged on the same side of described diaphragm body.
Preferably, described projection is arranged on the both sides of described diaphragm body.
Preferably, described locating piece and described this body by integral forming of diaphragm ground arrange.
The mold for producing automotive upholstery that the utility model provides, projection is set on the inwall by injection moulding die cavity to match with the through hole of diaphragm, diaphragm is accurately positioned on the assigned address of die cavity inwall, has improved the positional precision of diaphragm, thereby improved the quality of injection-molded item.On the other hand by projection by diaphragm fixedly in injection moulding die cavity, avoid diaphragm because of mobile, to produce position skew in injection moulding process, improved injection moulding precision, improved yields.At projection, fixedly on the basis of diaphragm, set up vacuum extractor, diaphragm and die cavity inwall are fitted tightly, avoid diaphragm in injection moulding process, to occur wrinkling, improved the presentation quality of injection-molded item.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the cut-away view of injection moulding die cavity in the utility model;
Fig. 3 is the structural front view of diaphragm in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As illustrated in fig. 1 and 2, mold for producing automotive upholstery comprises dynamic model 2 and cover half 3, and dynamic model 2 and cover half 3 form injection moulding die cavity 4 after direction of arrow matched moulds in Fig. 1, and the inwall 41 of injection moulding die cavity 4 is provided with two cylinder projections 42.
As Figure 1-3, mold for producing automotive upholstery also comprises diaphragm 1, and diaphragm 1 is placed between two cylinder projections 42.Diaphragm 1 comprises diaphragm body 11, and diaphragm body 11 is provided with locating piece 12, and locating piece 12 is one-body molded with diaphragm body 11.Locating hole 12 comprises the first locating piece 12a and the second locating piece 12b, on the first locating piece 12a and the second locating piece 12b, is respectively equipped with the manhole 15 adapting with projection 42 shapes.Projection 42 is through manhole 15, diaphragm 1 located and is fixed on to the assigned address on the inwall 41 of injection moulding die cavity 4.
Mold for producing automotive upholstery also comprises vacuum extractor (not shown), and vacuum extractor is communicated with injection moulding die cavity 4, by vacuumizing and adsorbing diaphragm 1, diaphragm 1 is fitted on the inwall 41 of injection moulding die cavity 4.
Embodiment in the utility model, only for the utility model is described, does not form the restriction to claim scope, and other substituting of being equal in fact that those skilled in that art can expect, all in the utility model protection domain.
