Mechanism used for separating product from fixed mould and capable of limiting slide block by adopting perpendicular locking surface for fixed mould and deep rib

Abstract

The invention discloses a mechanism used for separating a product from a fixed mould and capable of limiting a slide block by adopting a perpendicular locking surface for the fixed mould and a deep rib. The mechanism comprises a mould cavity (1), an inclined guide post (3) arranged on the fixed mould (2) and the slide block (4) which is arranged on a movable mould in a sliding mode, wherein one end, close to the mould cavity (1), of the slide block (4) is a side wall, which corresponds to the mould cavity (1), of the deep rib, and is positioned above a position, which corresponds to the mouldcavity (1), of a product edge; height of one end, close to the mould cavity (1), of the slide block (4) is a value obtained by subtracting 1.0-3.5mm from height of the deep rib; a stroke limiting mechanism is arranged between the slide block (4) and the movable mould; an inclined hole (5) which is in sliding fit to the inclined guide post (3) is formed in the slide block (4); the inclined hole (5)is greater than the outer diameter of the inclined guide post (3); one end, away from the mould cavity (1), of the slide block is equipped with an inclined surface (6); and a pressing surface (7) which presses the slide block (4) when the pressing surface is matched with the inclined surface (6) for closing the mould is arranged on the fixed mould (2). Compared with the prior art, the mechanism has characteristics of being simple in structure, convenient to maintain and repair, and capable of increasing the product yield.

Description

technical field [0001] The invention relates to a demoulding mechanism of a mould, in particular to a product fixed mold deep rib slider facing directly to lock and release the fixed mold mechanism. Background technique [0002] When the deep ribs of the product (generally, the height of the ribs is more than 1cm higher than the surface) is located on the fixed mold, the product tends to stay on the fixed mold when the mold is opened. The mold is disengaged, but in the actual production process, due to the influence of mold temperature and precision, it is often not easy for the spring block to disengage the product from the fixed mold in time, resulting in damage to the product or the final product falling off. Under the action of the spring, it is easy to leave traces on the product, the yield rate is relatively low, and the structure of the spring block is relatively complicated, which is not conducive to subsequent maintenance and maintenance.
