Description
Technical Field
The invention relates to the field of injection molds, in particular to a mold device for solving the problem that secondary injection is easy to damage the appearance dermatoglyph surface of a plastic part product.
Background
A front windshield sealing strip product on an automobile is formed by secondary insert injection molding (ASA hard glue and TPE soft glue), and a formed part (ASA hard glue) needs to be placed on a TPE soft glue mold for injection molding.
As shown in fig. 1, such a front windshield sealing strip product is a two-color molding product, and cannot be molded by a conventional two-color mold due to structural reasons, so that the front windshield sealing strip product can only be molded by secondary insert injection, and the manner is to place the appearance-molded ebonite product into a soft rubber mold again through manpower or a manipulator to be subjected to local secondary molding, and the appearance surface is easily crushed due to the fact that the appearance dermatoglyph surface can be directly pressed by a cavity after the mold is closed and the iron is harder than the injection molding.
As shown in fig. 2, the conventional countermeasure is to make a 0.2MM space away from the outer appearance area, but because the hard adhesive product is air-assisted hollow molding, a bright mark is formed on the outer appearance surface of the air passage corresponding to the middle of the product, and the outer appearance surfaces of the areas needing to be sealed at the two sides of the product are crushed. Affecting the appearance and quality of the product.
Disclosure of Invention
Therefore, a need exists for providing a mold device for solving the problem that secondary injection molding is prone to damage the skin and grain surface of the appearance of a plastic part product.
In order to solve the problems of the prior art, the invention adopts the technical scheme that:
the utility model provides a solve that secondary is moulded plastics and is easily hindered mould product outward appearance dermatoglyph face mould device, includes master model and public mould, and the space between master model and the public mould constitutes the cavity that is used for putting into the ebonite product, has the die cavity that is used for the fashioned flexible glue product between ebonite product and the cavity, and the part towards the public mould in the position of master model and ebonite product contact is replaced by the elastic component.
Preferably, the die further comprises a cushion block, and the elastic piece is connected with the female die through the cushion block.
Preferably, the pad is detachably connected with the female die.
Preferably, the core pulling device further comprises a core pulling sliding block, the core pulling sliding block is slidably arranged between the female die and the male die, and a die cavity is formed by the core pulling sliding block and gaps between the female die and the hard rubber product and between the core pulling sliding block and the male die.
Preferably, the material of the elastic member is super glue.
Compared with the prior art, the beneficial effect of this application is:
this application uses the elastic component to replace the master model to press at the position on ebonite product surface, when having solved the secondary flexible glue product of moulding plastics, how to avoid the technical problem that the iron master model crushes ebonite product surface when the compound die.

Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in fig. 3, the present application provides:
the utility model provides a solve twice and mould easily hinder a mould product outward appearance leather grain face mould device that moulds plastics, includes master model 1 and public mould 6, and the space between master model 1 and the public mould 6 constitutes the cavity that is used for putting into ebonite product 2, has the die cavity that is used for the shaping of flexible glue product 3 between ebonite product 2 and the cavity, and the part towards public mould 6 in the position of master model 1 and ebonite product 2 contact is replaced by elastic component 7.
Based on the above embodiments, the technical problem that the present application intends to solve is how to avoid the iron master mold 1 from crushing the surface of the hard rubber product 2 when the mold is closed. For this reason, the present application uses the elastic member 7 instead of the master model 1 to press the portion of the surface of the hard rubber product 2 so that the surface of the product is not crushed.
Further:
the die also comprises a cushion block 8, and the elastic part 7 is connected with the female die 1 through the cushion block 8.
Based on the above-described embodiments, the technical problem that the present application intends to solve is how to insert the elastic member 7 in the master model 1.
Further:
the cushion block 8 is detachably connected with the female die 1.
Based on the above-mentioned embodiments, the technical problem that the present application intends to solve is how to adjust the elastic member 7 so that it can properly press the hard adhesive product 2. For this purpose, the female die 1 and the elastic members 7 are connected by a removable and replaceable spacer 8, so that the positions of the elastic members 7 can be adjusted.
Further:
the core-pulling slide block is slidably arranged between the female die 1 and the male die 6, and a die cavity is formed by the core-pulling slide block and gaps among the female die 1, the hard rubber product 2 and the male die 6.
Based on the above embodiments, the technical problem to be solved by the present application is how to injection mold the soft gum product 3 with an inverted buckle. For this reason, this application is loosed core slider 4 and second through first and is loosed core slider 5 at two flexible glue products 3 of the both sides injection moulding of ebonite product 2.
