Embodiment 1

[0026] In Example 1, see Figure 1 to Figure 3 As shown, the first plastic product 310 and the second plastic product 320 are formed by double injection molding. Therefore, the molding machine is a double-shot molding machine, and the double-shot molding machine cooperates with two sets of injection molds to form the plastic product 300 sequentially. The two sets of injection molds are respectively the first set of injection molds and the second set of injection molds. The structure of the male mold part of the first set of injection mold and the second set of injection mold is exactly the same, but the structure of the female mold part is different.

[0027] In embodiment 1, the molding method of the plastic product of the present invention comprises the following steps:

[0028] Step S110: placing two sets of injection molds on the two-shot molding machine;

[0029] Step S120: connecting the high and low temperature controllers to the two sets of injection molds and the in...

Embodiment 2

[0035] In Example 2, see figure 2 and image 3 As shown, the first plastic product 310 and the second plastic product 320 are molded by insert molding. Therefore, the molding machine is two single-shot molding machines, and the two single-shot molding machines cooperate with two A plastic product 300 is formed by a set of injection molds, the two sets of injection molds are respectively the first set of injection molds and the second set of injection molds.

[0036] In embodiment 2, the molding method of the plastic product of the present invention comprises the following steps:

[0037] Step S210: Mounting the two sets of injection molds on two single-shot molding machines respectively;

[0038] Step S220: connecting the high and low temperature controllers to the two sets of injection molds and the injection molding machine, wherein the injection molding machine is used to inject hot melt plastic into the two sets of injection molds for injection molding;

[0039] Step S...

Abstract

The invention discloses a plastic product and a molding method thereof. The molding method comprises the following steps: (1) performing mold closing and heating on an injection mold controlled by a high / low-temperature controller; (2) obtaining a first plastic product through injection molding in the injection mold; (3) obtaining a second plastic product with metal effect on the first plastic product through injection molding in the injection mold; and (4) cooling the injection mold by using the high / low-temperature controller, opening the mold and getting a product consisting of the first plastic product and the second plastic product. The plastic product is the product generated through injection molding by using the above molding method.

Description

【Technical field】 [0001] The invention relates to a plastic product and its molding method, in particular to a metal effect plastic product and its molding method. 【Background technique】 [0002] Under the background of people's increasing pursuit of high-quality life, people's pursuit of products is also paying more and more attention to its shape and appearance decoration effect. For example, the appearance of 4C products (computers, communication products, consumer products and automobiles) is developing more and more More and more colorful, and people pay more attention to the application of environmental protection process and various fashionable personalized products. [0003] Frame decorations (such as decorative strips) used in automobiles and other products usually use post-surface treatment processes such as electroplating or painting after plastic molding to achieve a metallic effect. However, the electroplating or painting process has the following defects: 1. T...
