The double-color mold injection molding is one of the injection molding processes, the double-color is actually a secondary injection molding, the product generally comprises a main body (hard rubber) part and an outer wrapping (soft rubber) part, when the mold is manufactured, the hard rubber main body is manufactured firstly, the main body hard rubber mold is designed according to a normal design program, the outer wrapping (soft rubber) mold is designed by taking a hard rubber finished product as a reference, water does not need to be put again, the rear mold part is identical to the hard rubber main body, the front mold is different from the front mold in the rubber wrapping shape, the hard rubber main body is produced firstly during production, then the hard rubber main body is put into the outer wrapping mold, and the outer wrapping soft rubber is subjected to injection molding production. The double-color mold injection molding process has the advantages that: the partially formed article does not need to leave the original mold and enter another mold for subsequent injection of the next component material.
The prior art is characterized in that a researcher designs a positioning structure in advance before the second color slide block of the double-color mold is assembled, so that the first color product is shoveled before the second assembly is avoided, and glue overflow occurs when the second assembly is performed for injection.
Disclosure of Invention
The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing a pre-mold-closing pre-positioning structure of a second color slide block of a bicolor mold for positioning a product in advance and improving the reject ratio of the product.
The technical scheme of the utility model is as follows: the utility model provides a location structure in advance before two-shot mould second look slider compound die, two-shot mould includes first mould and second mould of penetrating, the second is penetrated the mould and is included front mould, back mould and set up the front mould with core between the back mould, be provided with the product shaping groove on the core, the bottom of front mould is provided with two sets of bullet needle subassembly, bullet needle subassembly includes bullet needle and spring, the one end of bullet needle passes through the spring is installed the bottom of front mould, the other end downwardly extending extremely the product shaping groove.
According to the scheme, the spring needle assembly is used for positioning the product before the two-shot die assembly, so that the front die core is smoothly matched with the first color product, and a qualified product is produced.
The bullet needle includes bullet syringe needle and needle bar that the integration set up, the diameter of bullet syringe needle is greater than the needle bar, the tip of needle bar is provided with the screens recess. Therefore, the clamping groove is used for positioning the spring needle and the clamping position of the injection molding product.
The bottom of the front mould is provided with a spring needle groove, and the front mould is provided with a spring groove for accommodating the spring at the end part of the spring needle. It follows that the spring needle groove is used for installing the spring needle, and the spring groove is used for installing the spring.
The spring is a heat-resistant round wire spring.

Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 to 6, the utility model discloses a pre-mold-closing positioning structure for a second color slide block of a bicolor mold, the bicolor mold comprises a first injection mold 1 and a second injection mold 2, the second injection mold 2 comprises a front mold 21, a rear mold 22 and a mold core 23 arranged between the front mold 21 and the rear mold 22, a product forming groove 3 is arranged on the mold core 23, two groups of spring needle assemblies are arranged at the bottom of the front mold 21, each spring needle assembly comprises a spring needle 4 and a spring 5, one end of each spring needle 4 is arranged at the bottom of the front mold 21 through the spring 5, the other end of each spring needle extends downwards to the product forming groove 3, and each spring 5 is a heat-resistant round wire spring.
In this embodiment, the reference number of the bicolor product is 100, a positioning groove 110 adapted to the spring pin 4 is provided on the bicolor product 100, a shape and position mechanism is provided between the front mold 21 and the core 23, the shape and position mechanism includes a shovel base and a second color slide block 200, the shovel base is used for pressing the second color slide block 300, and the second injection mold opening and closing is performed through the shape and position mechanism.
The bullet needle 4 includes bullet syringe needle 41 and needle bar 42 that the integration set up, the diameter of bullet syringe needle 41 is greater than the needle bar 42, the tip of needle bar 42 is provided with screens recess 421.
The bottom of the front mold 21 is provided with a spring pin groove 211, and the front mold 21 is provided with a spring pin groove 212 for accommodating the spring 5 at the end of the spring pin 41.
