Optical frame PU foaming mould

Abstract

The invention provides an optical frame PU foaming mould, and relates to the field of moulds. The optical frame PU foaming mould comprises a base, a mould platform and an upper cover shell, the mouldplatform is fixedly connected to the top of the base, the upper cover shell is clamped to the top of the base, and a fixed block is fixedly connected to the top of the base and also fixed to the sidewall of the mould platform; an optical frame groove is formed in the upper surface of the mould platform, a pressing plate is arranged in the upper cover shell, and an abutting device is arranged at the top of the pressing plate; a clamping groove is formed in the inner wall of the upper cover shell, a first slide groove is formed in the side wall of the base, a second slide groove is formed in the side wall of the fixed block, and clamping assemblies are arranged in the first slide groove and the second slide groove. By means of the optical frame PU foaming mould, the mould can be quickly sealed or detached, the pressing plate can stably abut against the upper surface of the mould platform, and the situation that gaps exist between the pressing plate and the mould platform after the mouldis used for a long term is avoided.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a PU foaming mold for mirror frames. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] In the prior art, the installation or disassembly of the mold during use is generally fixed by bolts, which is very inconvenient, wastes the time of the staff, and reduces work efficiency. Moreover, the mold will not match after a long time or multiple uses. The two molds cannot be closely fitted, and there may be a problem of ...

Problems solved by technology

[0003] In the prior art, the installation or disassembly of the mold during use is generally fixed by bolts, which is very inconvenient, wastes the time of the staff, and reduces work efficiency. Moreover, the mold will not match after a long time or multiple uses. The two molds cannot be closely fitted, and there may be a problem of gaps between the molds, which may cause unqualified products. Aiming at the deficiencies in the prior art, the present invention provides a PU foam mold for mirror frames to solve the problem of above question
