Description

[Technical field]

[0001] The invention relates to the technical field of mold mechanisms, in particular to a molding machine structure for three-color products. [Background technology]

[0002] IMR (In-Moudg Decoration by Roller) is a technology that prints decorative and functional patterns on foil using a high-precision printer. The foil is then fed into a special molding mold for precise positioning using a high-precision foil feeding device. The pattern on the foil is then transferred to the surface of the plastic product through the high temperature and high pressure of the injected plastic raw material.

[0003] A three-color injection molding machine usually has an injection molding machine and three injection pipes. After the mold is closed, the raw materials can be injected into the same mold one by one or at the same time. Figure 1 The three-color product shown in the figure requires three consecutive injections of raw materials when it is molded using a traditional three-color injection molding machine, which makes the molding cycle of the product longer. In addition, the three-color injection molding machine has certain limitations on the patterns that can be molded for three-color products, and the cost of molding products using a three-color machine is higher.

[0004] In view of this, it is necessary to provide a three-color product molding machine structure to solve the above problems. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is that a three-color product is molded by a traditional three-color injection molding machine, but when the product is molded by the traditional three-color injection molding machine, three consecutive injection molding of raw materials must be completed, which makes the molding cycle of the product longer, and the pattern molded by the three-color injection molding machine for the three-color product has certain limitations, and the cost of using the three-color machine to mold the product is high. Therefore, the present invention provides a molding machine structure for a three-color product to solve the above problems.

[0006] The solution of the present invention to solve the technical problem is: a three-color product forming machine structure, comprising:

[0007] A one-shot mold, wherein the one-shot mold is provided with a one-shot female mold and a one-shot male mold, wherein the one-shot female mold and the one-shot male mold are combined to form a one-shot product, and a film pressing frame is provided on one side of the female mold core of the one-shot female mold to form the product, wherein the film pressing frame is used to press the foil on the foil film so that the foil is tightly attached to the mold cavity of the female mold core;

[0008] IMR equipment, the IMR equipment includes a foil film and a foil feeding device, the foil film is arranged in the middle of the mother mold and the film pressing frame, the foil film is provided with a pattern foil printed by a printer, the foil feeding device feeds the pattern foil onto the foil film in the first shot mold for precise positioning, and then presses it into the mold cavity of the mother mold through the film pressing frame, and finally transfers the pattern foil on the foil film to the surface of the first shot product formed simultaneously with it through the high temperature and high pressure of the injected plastic raw material;

[0009] The two-shot mold is provided with a two-shot female mold and a two-shot male mold. After the three-color product is simultaneously molded into a one-shot product and a pattern foil in the one-shot mold, the two-shot female mold and the two-shot male mold are combined to form a two-shot product.

[0010] Preferably, the film pressing frame is made of S136 or 8407 steel.

[0011] Preferably, the printing machine used for printing the pattern foil is a high-precision printing machine, and the foil feeding device is a high-precision foil feeding device.

[0012] The beneficial effect of the present invention is that, by installing the IMR device on the one-shot mother mold side of the two-color molding machine, the pattern foil is sent to the foil film by the foil feeding device for positioning, and then pressed into the mold cavity of the mother mold core under the action of the film pressing frame, which can realize the production process of molding three-color products on the two-color machine. Compared with the three-color injection molding machine, this structure only needs to perform two moldings when molding the product, which can shorten the molding cycle of the product, and can meet the printing of complex patterns, and the equipment investment is low, saving production costs.
