Problems solved by technology

[0003] Two-color plastic products are two kinds of plastic materials injected on the same injection molding machine, and the plastic products are molded twice. Due to the constraints of the structure and appearance requirements of the plastic products, it is generally very difficult for the two plastic products to be well bonded together. Difficult, two-color plastic products usually have the defect of weak adhesion and easy to fall off

Embodiment Construction

[0019] In order to clarify the technical scheme and technical purpose of the present invention, the present invention will be further introduced below in conjunction with the accompanying drawings and specific implementation methods.

[0020] As shown in the figure, a plastic product injection-molded by a two-color mold includes a primary molding part 1 using PC material injection molding, a secondary molding part 2 using a mixture of ABS and PC, and the secondary molding part 2 is the same as the primary molding A number of toothed buckles 3 are provided at the part where the parts 1 are connected. The side of the primary forming part 1 is provided with a hole that fits with the shape of the toothed buckle 3. The primary forming part 1 is embedded in the toothed buckle 3. The secondary molding part 2 is connected with the secondary molding part 2 in the hole groove.

[0021] Toothed buckle 3 comprises the rectangular buckle cover of top and the buckle bar of bottom, as figur...

Abstract

The invention discloses a plastic product molded by injection using double-color mould, which comprises a one-step shaping part and a two-step shaping part, and the plastic product is characterized in that a plurality of tooth-shaped claspers are provided on the joint position of the one-step shaping part and the two-step shaping part, an groove embedded with the tooth-shaped claspers is providedat the circumference of the one-step shaping part, the tooth-shaped claspers are embedded in the groove. According to the invention, a structure of intersecting and locking of the one-step shaping part and the two-step shaping part of the double-color plastic products can be fixed, the disadvantages of the unstable stickiness and easy shedding of two-step shaping part of double-color plastic products in the prior art are overcome by the invention, and the invention has the advantages of simple structure, easy production of injection mould and convenient enforcement.

Description

technical field [0001] The invention relates to a plastic product injection-molded by a two-color mold, belonging to the field of mold injection molding. [0002] Background technique [0003] Two-color plastic products are two kinds of plastic materials injected on the same injection molding machine, and the plastic products are molded twice. Due to the constraints of the structure and appearance requirements of the plastic products, it is generally very difficult for the two plastic products to be well bonded together. Difficult, two-color plastic products usually have the defect of weak adhesion and easy to fall off. Therefore, before the design of plastic products, it is necessary to understand the physical properties of the injection molding material, the structure of the plastic product after molding, and the subsequent process of the two-color mold, so as to overcome the many defects caused by the difficulty in the molding process of the two-color plastic product, so...
