Method for forming bi-color products

Abstract

The invention provides an injection molding device. According to a double-color air blowing mold with an odd bit, a first mold cover plate is closed in the previous round, a second mold cover plate is opened, and a first-color material is formed corresponding to a first shoot gun; the second mold cover plate is closed in the next round, the first mold cover plate is opened, and a second-color material and the first-color material are formed together corresponding to a second shoot gun. According to a double-color air blowing mold with an even bit, a second mold cover plate is closed in the previous round, a first mold cover plate is opened, and a second-color material and a first-color material are formed together corresponding to a second shoot gun; the first mold cover plate is closed again in the next round, the second mode cover plate is opened, and the first-color material is formed corresponding to a first shoot gun. Due to the injection molding device, efficient and smooth continuous double-color air blowing injection molding can be achieved, and the whole device is more compact. The invention further provides a double-color product forming method and a camouflage product forming method, efficient and smooth continuous double-color air blowing injection molding of double-color products and camouflage products is achieved with the two methods respectively, and operation is easy and flexible to perform.

Description

[0001] The patent application of the present invention is a divisional application of Chinese patent application number 201410339254.6. The original application number is 201410339254.6, and the application date is July 17, 2014. The title of the invention is an injection molding device, a two-color product forming method and a camouflage product forming method. . technical field [0002] The invention relates to the field of injection molding equipment and injection molding technology for two-color materials, in particular to a molding method for two-color products. Background technique [0003] The structure of two-color material injection molding equipment is known, such as Chinese utility model patent CN201320005864.3, a kind of shoe sole injection molding equipment, including a blower, a preheating and cooling device, a mold and a supporting plate; the blower includes a goose head structure and Turntable; the preheating and cooling device includes a cooling fan, a heati...

Problems solved by technology

[0005] However, in the actual use process of this utility model, the structure is too complicated and huge, and the floor area is large. At least two operators are required to open and close the mold to prepare for the molding of the first color material and the second color material, and to take out the finished product. , the operation is cumbersome, the use method is single, the cost remains high, the flexibility is poor, and it is not easy to carry, it is difficult to promote, especially not conducive to the use of small and medium-sized processing enterprises, and the practicability needs to be improved

At the same time, the molding method of two-color products such as two-color shoes based on this utility model uses normal processing technology to preheat the two-color blow mold before formal processing, which will consume a large amount of injection molding materials, high cost, poor preheating effect, and low efficiency. low; and this utility model is not convenient for processing camouflage products such as camouflage shoes
