Description

Pressure injury prevention structure for double-color-mold secondary rubber coating and sealing Technical Field The utility model relates to an injection mold, in particular to a pressure injury prevention structure for secondary encapsulation and sealing of a double-color mold. Background The two-color injection refers to a process method that two kinds of plastics with different colors or different kinds of plastics are manufactured into finished products with different colors or different external hardness through injection molding procedures, and in the prior art, the method for two-color injection molding is divided into two-time injection molding, wherein the first finished product is used as an insert for the second injection molding, which is also called embedded injection. In the past, the contact sealing of the die sliding block and the die core steel material and the steel material is easy to crush and lighten when the primary injection molding product participates in the die sealing, and the sealing is invalid, flash and the like when the primary injection molding skeleton is deformed and easily causes secondary injection molding. Publication No.: CN211807590U a bicolor mould second color mould compound die anticollision structure, concretely relates to mould technical field, including the second template, the top surface of second template is provided with first template, and the top surface of second template is equipped with empty breach, the one end of empty breach is provided with the assembly groove, the inside of assembly groove is provided with the slider, one side of slider is provided with leans on the clamp plate, lean on the top surface of clamp plate to be equipped with first locating hole. The utility model is provided with the sliding block, the step block, the slotting and the shovel block, the sliding block is propped against the first template, a certain distance is ensured between the first template and the second template, and the die assembly reaches a certain distance, the sliding block is compressed into the second template by the shovel block, so that the step block on the sliding block is embedded into the slotting on the first template, and after die assembly of the second template and the third template is finished, the first template and the second template start to be die-assembled, and the internal structure of the second template is prevented from damaging the first color plastic product by compression. The structure of the anti-crush structure is complex and the adjustment is inconvenient. Disclosure of utility model The utility model aims to provide a crush injury preventing structure of a double-color-mold secondary encapsulation sealing adhesive, which solves the problem that a primary injection product reduces crush injury deformation during secondary injection. The technical scheme includes that the compression injury preventing structure comprises a rear die body and a product forming area arranged in the rear die body, wherein the product forming area is provided with a compression injury preventing component structure, the compression injury preventing component structure comprises a central soft nylon block component arranged in the middle of the product forming area of the rear die body and used for compressing a primary injection product, and a plurality of groups of compression slider structures arranged outside the product forming area of the rear die body and used for compressing one-time formed workpieces, and the compression slider structures comprise a group of central jacking compression slider structures arranged in the rear die body and a group of side compression slider structures arranged at the side ends of the rear die body.
