Abstract

The utility model provides a novel IML (In Mold Labeling) product film-forming mold, belonging to the field of mold. The novel IML product film-forming mold comprises an upper mold with a punch, a lower mold with a depression, locating pins fixed on four corners of the lower mold, a pressure plate sheathed at the bottom end of the punch, and an elastic part for connecting the pressure plate and the upper mold, wherein locating pin holes are formed in the pressure plate, corresponding to the positions of the locating pins, the wall of the depression extends upwards to form bosses, and grooves are formed at the periphery of the pressure plate correspondingly. The novel IML product film-forming mold solves the problems that the stretching height is low and the sheet is easy to crinkle, the pressure plate is sheathed at the periphery of the punch and the groove and boss structure is arranged on the pressure plate and the lower mold, so that the compaction degree is increased, sheet crinkling problem is avoided and the stretching height is improved; AB adhesive is coated at the bottom of the depression, therefore, the flatness of the formed sheet is improved, the impression operation is reduced and the buffer action is achieved.

Description

A kind of novel I ML product film mould

Technical field

The utility model relates to a kind of mould, is specifically related to a kind of novel I ML product film mould.

Background technology

At present, the mould using in hot press forming technology generally comprises upper die and lower die and pilot pin, in use, first the sheet material having processed is fixed in the depression of counterdie by pilot pin, then heating, again upper and lower mould is merged and draws desired shape, finally take out the sheet material of forming.Because in matched moulds process, sheet material is just positioned by four pilot pins, and pulling force is uneven, and product stretches highly generally in 6.5mm left and right, and easily wrinkling in the position, four angles of sheet material.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel I ML product film mould, and it can avoid sheet material corrugation in hot-forming process, and can increase the stretching height of product.

For addressing the above problem, the technical scheme that the utility model adopts is as follows:

A novel I ML product film mould, be provided with drift patrix, be provided with the counterdie of depression and be fixed on the pilot pin on four angles of counterdie, it is also included in the pressing plate and the elastomeric element that pressing plate is connected with patrix of drift bottom socket; Position corresponding to pilot pin in described pressing plate is provided with location pin hole; The wall of depression extends upward formation boss, and the surrounding correspondence of pressing plate is provided with groove.

Preferably, elastomeric element has 4, is separately positioned on four angles of pressing plate.

Preferably, elastomeric element is spring.

Preferably, in depression bottom, be equipped with AB glue.

Compared to existing technology, the beneficial effects of the utility model are:

A kind of novel I ML product film mould that the utility model provides, it,, by connecing pressing plate and the groove arranging and boss structure in patrix drift outer race on pressing plate and counterdie, has increased compaction degree, has improved the height that stretches, and can prevent sheet material corrugation; By increasing AB glue in depression bottom, improve the flatness after sheet forming, reduce impression.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of a kind of novel I ML product film mould of the present utility model after die sinking;

Fig. 2 is the schematic diagram after the mould matched moulds of Fig. 1;

Wherein: 1, patrix; 11, drift; 2, spring; 3, pressing plate; 31, groove; 32, location pin hole; 4, sheet material; 5, pilot pin; 6, counterdie; 61, depression; 62, boss; 7, AB glue.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of novel I ML product film mould, comprise: be provided with drift 11 patrix 1, be provided with the counterdie 6 of depression 61 and be fixed on the pilot pin 5 on 6 four angles of counterdie, it also comprises the pressing plate 3 and the elastomeric element 2 that pressing plate 3 is connected with patrix 1 of drift 11 bottoms sockets; Position corresponding to pilot pin 5 in pressing plate 3 is provided with location pin hole 32; The wall of depression 61 extends upward and forms boss 62, and the surrounding correspondence of pressing plate 3 is provided with groove 31.IML is decoration technique inside mold.

As a kind of preferred embodiment, elastomeric element 2 is provided with 4, and is separately positioned on 4 angles of pressing plate 3.In the present embodiment, elastomeric element 2 is springs.

When sheet material 4 is placed on depression 61, with 5 pairs of sheet materials 4 of pilot pin, position, after matched moulds, the active force that elastomeric element 2 gives also can increase compaction degree; The design of the boss 62 on pressing plate 3 upper grooves 31 and counterdie 6 also can increase the compaction degree of mould to sheet material 4, and, it can also guarantee that sheet material 4 is stressed evenly, tensile force is not exclusively concentrated in pilot pin 5, thereby avoid four angles of sheet material 4 wrinkling, and can highly be increased to 10mm left and right so that sheet material 4 stretches.

In depression 61 bottoms, be equipped with AB glue 7, after matched moulds, sheet material 4 and AB glue 7 Elastic Contact, the flatness after sheet material 4 moulding is better, and can reduce impression; In addition, if product surface has projection or recessed pattern, there is recessed or protruding modelling on the surface of corresponding AB glue 7, makes mould can be applied to polytype production, makes its range of application wider.

Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
