Deep-cavity mold with convenient demolding function

Abstract

The invention discloses a deep-cavity mold with a convenient demolding function. The deep-cavity mold with the convenient demolding function comprises a front mold cover plate supported through a moldbracket, wherein a mounting through hole is formed in the front mold cover plate; an exhaust cylinder, a mounting shaft, a connecting block and a linear driving device which are connected in sequenceare arranged at the lower end of the front mold cover plate; the driving device is fixed on the mold bracket; the bottom of the connecting block is connected with the driving end of the driving device; a mounting hole is formed in the top of the connecting block; the axis of the mounting hole is parallel to the driving direction of the driving device; a magnet is arranged at the hole bottom of the mounting hole; the bottom of the exhaust cylinder is connected with one end of the mounting shaft; the other end of the mounting shaft is inserted into the mounting hole and in contact with the magnet; the mounting shaft is adsorbed by the magnet; and after the driving device is started, the exhaust cylinder can be inserted into the mounting through hole, as well as the top of the exhaust cylinder and the glue sealing surface of the front mold cover plate can be coplanar. When the deep-cavity mold with the convenient demolding function is adopted for the injection molding of a product, no burrs are formed on the surface of the product and the surface quality of the product is improved.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a deep cavity mould, which is convenient for demolding. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is achieved through injection molding machines and molds. [0003] In the packaging of some liquor and other bottles, in order to improve the shockproof coefficient and the exquisiteness of the packaging, plastic boxes are often selected as their packaging boxes. In the production of plastic boxes, a b...

Problems solved by technology

[0004] The purpose of the present invention is to provide a deep cavity mold that is easy to demould, and solve the problem that in the existing deep cavity injection molding method, since there is no support surface near the bottom grinding gap on the product, and the gas fluidity is large, it is easy to There are burrs on the product, which makes the injection molded product fluffy
