Problems solved by technology

The process of IMD pressing molding process is mold loading, heating, molding, pressure holding, inserting U-shaped inserts, mold opening, and taking parts; the produced sheet is vertical to the direction of mold release, and there is no movement in the transverse direction mechanism, so it is impossible to make a second bend; it cannot meet the requirements of anti-hemming

Embodiment Construction

[0024] The present invention is described by taking an anti-hemming mold assembly as an embodiment.

[0025] Such as image 3 and Figure 4 As shown, an anti-hemming mold assembly includes a panel 1, an upper solid plate 2 is suspended and installed under the panel by a first spring 61, a row position 18 is installed on the upper solid male plate, and a shovel 19 is arranged on the panel 10;

[0026] The punch base 20 is fixedly installed on the upper solid public plate 2, the second punch 32 and the first punch 31 are fixed on the punch base 20, and the movement of the shovel drives the movement of the rows to match the second punch ;

[0027] The bottom of the first punch 31 and the second punch 32 are matched with the inner holder 10, and the first punch 31 and the second punch 32 are matched with the inner holder 10 to form the PET film 10; Punch 31, second punch 32 and guide post 5 of punch base 20, guide sleeve 7, pin 21 and screw 22;

[0028] The bottom of the inner...

Abstract

The invention discloses a mold assembly for reverse edge covering. The mold assembly comprises a face plate. An upper fixed male plate is mounted below the face plate through first springs in a hung manner, and provided with a slide, and a wedge is arranged on the face plate. A male mold base is fixedly mounted on the upper fixed male plate and fixedly provided with a second male mold and a first male mold, and the slide is matched with the second male mold. The lower portion of the first male mold and the lower portion of the second male mold are matched with an inner support, and a PET thin film is formed by means of matching of the first male mold, the second male mold and the inner support. The bottom of the inner support is assembled in a female mold. The top ends of second springs are fixed to the bottom of the inner support, and the bottom ends of the second springs are limited and fixed to a first bottom plate. The female mold is fixed to the first bottom plate, an inner hole male mold is further fixedly mounted on the first bottom plate, and the bottom face of the inner hole male mold is fixed through a second bottom plate. A through hole is formed in the first bottom plate, the inner hole male mold is assembled in the through hole, and the bottom of the through hole is sealed by the second bottom plate.

Description

technical field [0001] The invention relates to a molding die, in particular to an anti-hemming die assembly. Background technique [0002] The products manufactured by IMD process in the existing market are all made by one-shot molding technology. Its specific process: blanking mold→forming mold→injection molding; that is: when the sheet is printed, use the blanking mold to blank, and take the blanked sheet to the ordinary forming mold for molding (one-time bending) , to form the desired radian, and then put the formed sheet into the cavity of the injection mold for injection molding. This kind of product made by one-time bending will have a white phenomenon, and there is a small section on the side of the product that cannot be attached to the film, which will affect the appearance of the product; [0003] The structure of the traditional general molding die assembly is as follows figure 1 and figure 2 As shown, it includes panel 1, upper solid plate 2, punch 3, punch...
