Abstract

The invention relates to an IMR (in-mold molding) mold structure which comprises a female mold core, a film pressing frame is fixed on one side of the female mold core, a through hole is formed in the film pressing frame, a layer of film is arranged between the film pressing frame and the female mold core during IMR molding of a product, and the end, needing IMR molding, of the product can penetrate through the through hole to be in contact with the film and then is pressed in a groove of the female mold core. The thin film is attached to the end, needing IMR forming, of the product; the mold has the beneficial effects that by designing the structure of the film pressing frame on the side of the female mold core, when the depth of the product subjected to IMR forming is larger than 2 mm, the end, needing IMR forming, of the product can penetrate through the through hole of the film pressing frame, and then a film is formed at the end of the product; therefore, the IMR forming process of the product with the depth of more than 2mm can be realized.

Description

[Technical field]

[0001] The invention relates to the technical field of mold mechanisms, in particular to an IMR molding mold structure. [Background technology]

[0002] like Figure 1 The product shown in the figure is produced using the traditional IMR molding process, that is, IMR molding is performed directly at the male and female mold joining lines in the mold. However, the depth of this product is greater than 2 mm, and when the film in IMR molding is stretched to this depth, the film will break, so this product cannot be IMR molded.

[0003] In view of this, it is necessary to provide an IMR molding mold structure to solve the above problems. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is that a product is produced by using a traditional IMR molding process, but the depth of the product is greater than 2 mm, and when the film in the IMR molding is stretched to this depth, the film will break, so that the product cannot be IMR molded. Therefore, the present invention provides an IMR molding mold structure to solve the above problem.

[0005] The solution of the present invention to solve the technical problem is: an IMR molding mold structure, comprising:

[0006] A mother mold core, wherein a film pressing frame is fixed on one side of the molded product, and the film pressing frame is provided with a through hole. When the product is IMR molded, a film is provided between the film pressing frame and the mother mold core. The product can pass the end that needs IMR molding through the through hole and contact the film, and then press it into the groove of the mother mold core, so that the film is attached to the end of the product that needs IMR molding;

[0007] A male mold core is used to cooperate with the female mold core to form a product.

[0008] Preferably, the film pressing frame is provided with four through holes, which are respectively used for IMR molding of four products.

[0009] Preferably, the film pressing frame is made of S136 or 8407 steel.

[0010] The beneficial effect of the present invention is that, by designing the structure of the film pressing frame on the side of the mother mold core, the present invention enables the end of the product that needs IMR molding to pass through the through hole of the film pressing frame when the depth of the IMR molded product is greater than 2 mm, and then the film is molded on one end of the product, that is, the IMR molding process of products with a depth of more than 2 mm can be realized.

[0015] To further illustrate the technical means and effects adopted by the present invention, the following is a detailed description in conjunction with the embodiments of the present invention and the accompanying drawings.

[0016] The present invention provides a mold structure for IMR molding, comprising:

[0017] A mother mold core 20, wherein a film pressing frame 101 is fixed on one side of the molded product of the mother mold core 20, and the film pressing frame 101 is provided with a through hole 102. When the product is IMR molded, a film 103 is provided between the film pressing frame 101 and the mother mold core 20. The end of the product that needs IMR molding can pass through the through hole 102 and contact the film 103, and then be pressed into the groove 104 of the mother mold core 20, so that the film 103 is attached to the end of the product that needs IMR molding;

[0018] The male mold core 30 is used to cooperate with the female mold core 20 to form a product.

[0019] The film pressing frame 101 is provided with four through holes 102, which are respectively used for IMR molding of four products.

[0020] The film pressing frame 101 is made of S136 or 8407 steel.

[0021] The beneficial effect of the present invention is that, by designing the structure of the film pressing frame 101 on the side of the mother mold core 20, when the depth of the IMR molded product is greater than 2 mm, the end of the product that needs to be IMR molded can be passed through the through hole 102 of the film pressing frame 101, and the film 103 can be molded on one end of the product, that is, the IMR molding process of products with a depth of more than 2 mm can be realized.

[0022] It should be pointed out that the present invention is not limited to the above-mentioned implementation modes, and any simple modifications, equivalent changes and modifications made to the above-mentioned embodiments by any technician familiar with the profession based on the technical solution of the present invention fall within the protection scope of the present invention.
