The further technical scheme is as follows:

the upper connecting part and the lower connecting part are connected in a matched manner through connecting bolts.

And a limiting part is arranged on the outer surface of the die after die assembly, and is used for limiting the connecting bolt.

The limiting part is of an annular structure, and the distance between the outer side of the annular structure and the outer wall of the die body is smaller than the length of the connecting bolt.

The upper connecting parts are symmetrically arranged on two sides of the upper die body, and the lower connecting parts are symmetrically arranged on two sides of the lower die body.

The upper connecting part and the lower connecting part are of block structures, and bolt holes are formed in the block structures.

The beneficial effects of the utility model are as follows:

the upper and lower connecting parts are respectively arranged on the upper die body and the lower die body and are integrally arranged with the die body, and the die can be directly locked by utilizing the cooperation of the upper and lower connecting parts, so that the operation is convenient, and the quick disassembly and replacement of the die are realized.

According to the utility model, no additional independent connecting block and locking piece are required to be arranged, so that the damage and loss of the connecting block are avoided. Meanwhile, the use of the connecting blocks is canceled, and the management cost of workshops is saved.

The limiting part is arranged on the die body, so that the bolts can be prevented from falling off after unscrewing, the bolts are prevented from being separated from the connecting part, and the die is conveniently and directly locked again by using the original connecting bolts.

Additional features and advantages of the utility model will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.

Detailed Description

The following describes specific embodiments of the present utility model with reference to the drawings.

Referring to fig. 1, 2 and 3, the mold integrated locking structure of the present embodiment includes an upper mold body 1 and a lower mold body 2, an upper connecting portion 11 is provided in the upper mold body 1, a lower connecting portion 21 is provided in the lower mold body 2, the lower connecting portion 21 is used for being connected with the upper connecting portion 11 in a matching manner, and locking or releasing the upper mold body 1 and the lower mold body 2, wherein an outer surface of the upper connecting portion 11 or the lower connecting portion 21 is flush with an outer surface of a mold after mold closing.

The mould integral type locking structure of this embodiment, upper and lower connecting portion set up respectively at last mould body 1 and lower mould body 2, with mould body integral type setting, then utilize upper and lower connecting portion locking to be connected, need not extra connecting block and retaining member, not fragile and lose.

In the above embodiment, the upper connection portion 11 and the lower connection portion 21 are cooperatively connected by the connection bolt 3.

Preferably, the upper connecting portion 11 and the lower connecting portion 21 are each of a block structure, and bolt holes 111 are formed in the block structure. The outer surface of the lower connecting part 21 is flush with the outer surface of the lower die body 2, the upper connecting part 11 is positioned in the upper die body 1, when the upper die body 1 and the lower die body 2 are assembled, the upper connecting part 11 is positioned on the inner side of the lower connecting part 21 and parallel to the lower connecting part, and the positions of the bolt holes 111 on the upper connecting part and the lower connecting part correspond to each other.

When the upper and lower dies are required to be locked, the bolt holes 11 on the upper and lower connecting portions 11 and 21 are aligned, and the upper and lower dies are locked by tightening the connecting bolts 3.
