Description

Composite material forming die capable of exhausting air under negative pressure

Technical Field

The utility model relates to a forming die especially is a can exhaust combined material forming die of negative pressure.

Background

The composite material products generally belong to thin-wall parts, and for a compression molding process, the parting of the products is well studied, and if the parting is not proper, the product is difficult to demould, and even the material cannot be compacted to cause defects and scrap.

In certain products, no or only very small corner rounding is allowed for the edge of the product, so that the female die of the die is usually required to be processed by electric spark, and the female die is difficult to polish, thereby increasing the processing difficulty and the processing cost.

In the forming process of the composite material product, defects exist in the product due to unsmooth exhaust, and the product quality is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a be used for solving among the prior art to the slim product drawing of patterns be difficult, produce easily and report the waste product, when having little fillet or no fillet requirement to the product edge, require higher to the bed die, increase the processing degree of difficulty and the processing cost the problem can the carminative combined material forming die of negative pressure.

In order to solve the technical problem, the utility model provides a can carminative combined material forming die of negative pressure, include the upper punch, down the terrace die and enclose the frame, enclose the frame and set up between upper punch and lower terrace die, the upper punch, down the terrace die and enclose and constitute into the die cavity between the frame, at least one side that encloses the frame sets up the extraction opening, and the extraction opening intercommunication become the die cavity.

Preferably, the upper side and the lower side of the enclosure frame are both provided with positioning bulges, and the inner side of the upper male die and the inner side of the lower male die are both provided with positioning grooves which are opposite to the positioning bulges.

Preferably, a sealing strip is arranged between the upper male die and the enclosure frame.

Preferably, a sealing strip is arranged between the lower convex die and the surrounding frame.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the utility model forms a molding cavity of a thin product by enclosing the upper male die, the lower male die and the enclosing frame, so that the demolding is easier and the rejection rate is reduced;

2. the circumferential surface of the product is formed by the enclosing frame, the turning structure of the enclosing frame can be adjusted according to the requirement that the edge of the product has a small round angle or does not have the small round angle, and the turning angle is processed, so that the die opening is easier, and the die opening processing difficulty and the processing cost are reduced;

3. the air faucet is arranged at the air exhaust port of the surrounding frame and communicated with the vacuumizing device, so that the cavity can be assisted to exhaust, the smoothness of a pouring process is ensured, the internal defect rate of a product is reduced, and the product quality is improved.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive effort.

FIG. 1 is one of the exploded views of the present embodiment;

FIG. 2 is a second exploded view of the present embodiment;

FIG. 3 is a sectional view of the present embodiment;

the device comprises an upper male die, a lower male die, a surrounding frame, a forming die cavity, an air exhaust opening, a positioning protrusion and a positioning groove, wherein the upper male die is 1, the lower male die is 2, the surrounding frame is 3, the forming die cavity is 4, the air exhaust opening is 5, the positioning protrusion is 6, and the positioning groove is 7.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, 2 and 3, the utility model provides a can carminative combined material forming die of negative pressure, include terrace die 1, lower punch 2 and enclose frame 3, enclose frame 3 and set up between terrace die 1 and lower punch 2, and terrace die 1, lower punch 2 and enclose to constitute into die cavity 4 between the frame 3, and a side that encloses frame 3 sets up extraction opening 5, and extraction opening 5 communicates into die cavity 4. The embodiment has the advantages of simple structure and convenient processing, and is particularly suitable for molding test pieces and products with higher requirements.

In other embodiments, the upper side and the lower side of the surrounding frame 3 are provided with positioning protrusions 6, and the inner side of the upper punch 1 and the inner side of the lower punch 2 are provided with positioning grooves 7 corresponding to the positioning protrusions 6.

Through inserting positioning protrusion 6 into positioning groove 7, accurate location guarantees the compound die convenience and the product precision of mould.

In other embodiments, a sealing strip is arranged between the upper male die 1 and the surrounding frame 3, a sealing strip is arranged between the lower male die 2 and the surrounding frame 3, so that pouring liquid is prevented from overflowing, the product precision is improved, and the molding cavity 4 is set to be sealed except for the extraction opening 5.
