Abstract

A demoulding structure comprises a female mould centre plate, an elastic block, a female mould centre, a limiting piece, a mechanical on-off device, and a resin on-off device. A first activity strokeis arranged between the female mould centre plate and a female mould plate; the elastic block is arranged in a female mould core and arranged on the inner side of a product; one end of the female mould centre is fixed into the female mould centre plate, and the other end of the female mould centre abuts against the inner side of the product; one end of the limiting piece is fixed into the elasticblock, and a second activity stroke is arranged between the other end of the limiting piece and the female mould core; the mechanical on-off device is provided with a locking sleeve and a locking seat, the locking sleeve is fixed into a male mould core, one end of the locking seat is fixed into the elastic block, and the other end of the locking seat is locked in the locking sleeve; and the resinon-off device is provided with a nylon sleeve and a conical screw, the nylon sleeve is fixed into a male mould plate, and the conical screw is fixed to the female mould plate through a pulling rod. According to the demoulding structure, by arranging the structures such as the female mould centre plate, the female mould centre and the elastic block, staged jacking is conducted after a mould is opened, the problem that the product adheres to the female mould is solved, and the product appearance surface can be made into a high mirror surface.

Description

【Technical Field】 [0001] The invention relates to a mold structure, in particular to a demolding structure. 【Background technique】 [0002] In the production of plastic products, if the products are all molded on the side of the master mold, the product will stick to the master mold when the mold is opened. [0003] See figure 1 As shown, it shows a schematic diagram of a product. The product has a relatively high 10-circle circle, all molded on the side of the master mold, and the appearance surface 11 is a high mirror surface. Therefore, the product 10 will stick to the master mold when the mold is opened after molding, and the appearance surface 11 is not allowed to run off the slider during injection molding, and the high mirror surface cannot be polished. The product 10 cannot be injection molded. [0004] In view of this, it is really necessary to develop a demolding structure to solve the problem that the above-mentioned product 10 is molded on the master mold side and the ...
