SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an utilize from tearing open limit and seal mould structure of glue is provided, its product that can avoid machine-shaping runs the overlap to make the product qualification rate higher.

In order to solve the technical problem, the utility model provides an utilize mould structure from tearing open limit and sealing glue, include:

the heating plate is provided with a plurality of flow channels;

a mould benevolence board, mould benevolence board have and be used for the first surface that folds each other with the hot plate, be provided with a plurality of shaping chamber in the mould benevolence inboard, every shaping chamber all has first open end on the first surface of mould benevolence board, shaping chamber and runner one-to-one set up, the first open end in every shaping chamber all is linked together with corresponding runner, be provided with a plurality of annular groove on the first surface of mould benevolence board, annular groove and shaping chamber one-to-one set up, every annular groove all centers on the first open end in corresponding shaping chamber.

Preferably, the inner edges of the annular grooves are close to the first opening ends of the corresponding forming cavities.

Preferably, the groove bottom of the annular groove is in a shape of a concave arc in the width direction of the annular groove, and the width of the groove opening part of the annular groove is larger than that of the groove bottom.

Preferably, the heating plate is provided with a plurality of positioning lugs, the mold core plate is provided with a plurality of positioning grooves, the positioning lugs and the positioning grooves are arranged in a one-to-one correspondence manner, and each positioning lug is used for being clamped into the corresponding positioning groove.

After the structure more than adopting, compared with the prior art, the utility model, have following advantage:

the utility model discloses a mould structure, in the injection moulding stage, the runner that liquid material passes through on the hot plate enters into the one-tenth die cavity of mould benevolence inboard, after liquid material is full of the one-tenth die cavity, owing to be provided with the annular groove on the first surface of mould benevolence board, make before the pressurize stage, the liquid material in the annular groove solidifies in advance, thereby sealed the liquid material that continues the infiltration, played sealed effect, make the product can not run the overlap, after the processing is accomplished, as long as remove annular groove fashioned waste material can, like this, the utility model discloses a mould structure can avoid machine-shaping's product to run the overlap, so that the product qualification rate is higher.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, the mold structure using the self-edge-removing sealant of the present invention includes a heating plate 10 and a mold core plate 20.

The heating plate 10 is provided with a plurality of runners 11.

The mold core plate 20 has a first surface for folding with the heating plate 10, and when the mold core plate 20 and the heating plate 10 are locked and fastened, the first surface of the mold core plate 20 is pressed against the heating plate 10.

A plurality of molding cavities 21 are arranged in the mold core plate 20, each molding cavity 21 has a first open end on the first surface of the mold core plate 20, the molding cavities 21 are arranged in one-to-one correspondence with the runners 11, the first open end of each molding cavity 21 is communicated with the corresponding runner 11, and in the injection molding stage, liquid materials flow into the corresponding molding cavity 21 through the runners 11.

The first surface of the mold core plate 20 is provided with a plurality of annular grooves 22, the annular grooves 22 are arranged in one-to-one correspondence with the molding cavities 21, and each annular groove 22 surrounds the first opening end of the corresponding molding cavity 21.

The inner edges of the annular grooves 22 are close to the first open ends of the corresponding molding cavities 21.

The groove bottom 221 of the annular groove 22 is in a concave arc shape in the width direction of the annular groove 22, and the width of the notch 222 of the annular groove 22 is larger than that of the groove bottom 221, so that the cross section of the annular groove 22 is in an open shape, and the molding waste in the annular groove 22 can be easily taken out.

Heating plate 10 on be provided with a plurality of locating convex blocks 12, be provided with a plurality of positioning groove on the mould benevolence board 20, locating convex block 12 sets up with the positioning groove one-to-one, every locating convex block 12 all is used for going into corresponding positioning groove in the card, when heating plate 10 and mould benevolence board 20 locking fit, every locating convex block 12 all goes into corresponding positioning groove in the card for the location is firm between heating plate 10 and the mould benevolence board 20.

The utility model discloses a mould structure, in the injection moulding stage, the liquid material enters into the one-tenth die cavity 21 in the mould benevolence board 20 through runner 11 on the hot plate 10, is full of into die cavity 21 at the liquid material after, owing to be provided with annular groove 22 on the first surface of mould benevolence board 20, the liquid material can infiltrate in the annular groove 22, before the pressure-holding stage, the liquid material in the annular groove 22 solidifies in advance to the liquid material who continues the infiltration has been sealed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention, but should not be construed as limiting the claims, and the present invention is not limited to the above-described embodiments, but may be modified in various ways. In conclusion, all the variations that can be made within the scope of the independent claims of the present invention are within the scope of the present invention.
