Problems solved by technology

[0002] When injection molding products need to stick to the mother mold, the mold ejection of the mold opening mechanism in the prior art uses an oil cylinder. When the male and female molds are opened, the oil cylinder is ejected to ensure that the product sticks to the mother mold. The mixer or the ejector cylinder is externally connected to the oil circuit neutron machine, otherwise it is difficult to ensure that the male and female molds are opened synchronously when the oil cylinder is ejected, and sometimes it is difficult to ensure synchronous mold opening, and the mold opening mechanism of the prior art uses hardened materials. The cost of the mechanism is relatively high. This structure requires that the ejector plate of the mold can only be returned by a spring. For large molds or molds with a large ejection stroke, this mechanism will be limited

Abstract

The invention belongs to the technical field of an injection mould produced by an automobile component, and provides a synchronous mold-opening mechanism. The synchronous mold-opening mechanism comprises a master mold, a male mold, mold feet, an ejector plate member and a lower fixed plate, the male mold and the master mold have a hook member, an upper end of the hook member is fixed at the mastermold, the hook member integrally passes through the master mold and is connected with the ejector plate member in a cooperation mode, and a mechanical-type synchronous mold-opening apparatus used fordriving synchronous mold-opening of the master mold and the ejector plate member is arranged at a cooperation position of the hook member and the ejector plate member. The synchronous mold-opening mechanism can realizes synchronous mold-opening of the master mold and the ejector plate member through a driving lever and a sliding block, by employing a mechanical type, the whole mold-opening mechanism has the advantages that the structure is simple, the synchronism is good, the integral manufacture cost is low, and the injection moulding quality of the final product can be guaranteed.
