Embodiment Construction
[0020] see figure 2 As shown, in this embodiment, the forced demoulding mechanism of the female mold of the present invention is applied in a mold. The demoulding mechanism includes:
[0021] A guide block 400, one end of which is fixed in the female template 200 and the female mold core 210 of the mold, and the guide block 400 is provided with an inclined T-shaped bump;
[0022] The master mold insert 500 is set in the master mold core 201 and is provided with a first elastic element 501 between the master mold core 201. When the mold is closed, the first elastic element 501 is in a compressed state. In this embodiment The first elastic element 501 is a spring, and the mother mold insert 500 is provided with an inclined T-shaped groove 502, and the inclined T-shaped groove 502 is matched with the above-mentioned inclined T-shaped bump, and the above-mentioned T-shaped bump Set in the T-shaped slot 502 so that the female mold insert 500 slides obliquely along the guide bloc...

The invention relates to a forced demolding mechanism for a female die, which is applied to a die. The die comprises a female die plate, a male die plate, a female die core and a male die core. The forced demolding mechanism for the female die comprises a guide block, a female die insert, a baffle block and a forced demoulding insert, wherein one end of the guide block is fixed in the female die plate and the male die core of the die; the female die insert is arranged in the female die core, an elastic element is arranged between the female die insert and the female die core, and the female die insert obliquely slides along the guide block when the die is opened; one end of the baffle block is arranged in the female die insert, the other end of the baffle block extends out of the female die insert, and a travel space is formed between the baffle block and the female die insert; and the forced demoulding insert is arranged in the female die core, an elastic element is arranged between the female die core and the forced demoulding insert, and the forced demoulding insert is connected to the female die insert and a product barb. The forced demoulding mechanism for the female die is simple in structure, can realize forced demoulding with fewer parts just by once opening, and reduces the die cost.
Description
【Technical field】 [0001] The invention relates to a mold mechanism, in particular to a forced demoulding mechanism for a mother mold. 【Background technique】 [0002] When producing plastic products, when there is a mechanism that requires forced demoulding on the outer edge of the product, such as figure 1 As shown in the product 100, the barb 110 on the outer edge needs to be demoulded. The traditional mold needs to be produced with a two-plate and half-mould structure. higher cost. [0003] In view of this, it is necessary to provide a new type of forced demoulding mechanism for the master mold. The forced demoulding mechanism for the master mold has a simple structure, only needs to open the mold once, and can realize forced demoulding with fewer parts. 【Content of invention】 [0004] Therefore, the object of the present invention is to provide a forced demoulding mechanism for a master mold, which has a simple structure, only needs to open the mold once, and can real...
