Abstract

The utility model discloses a film suction mechanism which is characterized by comprising a plurality of air exhaust holes arranged in a female die plate, wherein one end of each air exhaust hole extends from the inside of the female die plate to be connected with an outside air exhaust device; the other end of the air exhaust hole abuts on the top surface of a female die insert in the female die plate and is communicated with an air exhaust groove arranged on the top surface of the female die insert; the top surface and the bottom surface of the female die insert are respectively provided with a circle of air exhaust groove along the circumference of the female die insert; and the air exhaust grooves on the top surface and the bottom surface are communicated with each other through a plurality of through holes. According to the film suction mechanism disclosed by the utility model, continuous air suction can be performed on the cavity in the female die insert through the air exhaust holes and the air exhaust grooves in the injection molding process, so that a negative-pressure environment can be formed in the cavity, and a film in the cavity is always kept adsorbed to be in a level state, thereby keeping patterns on the film unchanged and improving the film lamination effect.

Description

Film adsorption mechanism

Technical field

The utility model relates to a kind of film adsorption mechanism, belongs to technical field of mold.

Background technology

At present, the shell of many notebooks is all with decorative pattern, is with dapple notebook computer shell for this, when adopting mold injection molding, need to arrange one and be with dapple film in die, and then injection moulding, the decorative pattern on the film is on the notebook computer shell with regard to the product that is transferred to injection mo(u)lding like this.Yet because film is thinner, yielding or displacement is smooth if film can not keep in injection moulding process, can make the decorative pattern distortion that is transferred on the notebook computer shell, affects the press mold effect.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of film adsorption mechanism, in injection moulding process, makes film remain smooth, thereby makes decorative pattern on the film shape that remains unchanged, and improves the press mold effect.

For solving the problems of the technologies described above, the utility model provides a kind of film adsorption mechanism, it is characterized in that, comprise a plurality of aspirating holes that are arranged in the caster, aspirating hole one end extends to the air extractor of outside in the caster and is connected, the aspirating hole other end arrives at the end face of the mother module core in the caster, with the groove perforation of bleeding set on the mother module core end face; The one circle groove of bleeding is being set around the mother module core respectively on the end face of mother module core, the bottom surface, and end face is connected by a plurality of through holes with the groove of bleeding on the bottom surface.

The groove of bleeding on the bottom surface of described mother module core is pressed close to mutually with the film in the die cavity.

Mother module core and the male die core of described die cavity after by matched moulds forms.

When described air extractor was bled, described film was adsorbed on the bottom surface that is affixed on described mother module core.

The beneficial effect that the utility model reaches:

Film adsorption mechanism of the present utility model in injection moulding process, is constantly bled to the die cavity in the die by aspirating hole and the groove of bleeding, make the environment that forms negative pressure in the die cavity, make the film in the die cavity remain the formation state that is adsorbed, thereby make decorative pattern on the film shape that remains unchanged, improve the press mold effect.

Description of drawings

Fig. 1 is film adsorption mechanism schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.

As shown in Figure 1, film adsorption mechanism of the present utility model comprises a plurality of aspirating holes 2 that are arranged in the caster 1, aspirating hole 2 one ends 21 extend to the air extractor of outside in the caster 1 and are connected, aspirating hole 2 other ends 22 arrive at the end face 31 of the mother module core 3 in the caster 1, with groove 41 perforations of bleeding set on the mother module core end face 31.The one

circle groove

41,42 of bleeding is being set around the mother module core respectively on the end face 31 of mother module core, the bottom surface 32, and end face 31 is connected by a plurality of through holes 5 with the groove 41 of bleeding, 42 on the bottom surface 32.The groove 42 of bleeding on the bottom surface 32 of mother module core is pressed close to mutually with the film 7 in the die cavity 6.Like this, when air extractor is bled, the groove 42 of bleeding of the groove 41 of bleeding by aspirating hole 2, mother module core end face 31, through hole 5, mother module core bottom surface 32 is extracted out the gases in the die cavity 6, make die cavity 6 interior formation negative pressure, make the film 7 that arranges in the die cavity be adsorbed to the closing-type inner cavity surface above, can keep smooth indeformable.

Die cavity 6 is mother module core 3 and the cavity that is arranged at a relative closure of the male die core 9 matched moulds formation in the male model plate 8.

The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
