A micro-opening device for unilateral tearing of a glass fiber reinforced plastic forming hydraulic press

Abstract

The invention discloses a micro-opening device for unilateral tearing of a glass fiber reinforced plastic forming hydraulic press, which comprises a bottom plate, a base fixedly connected to one side of the top of the bottom plate, and a control box fixedly connected to the other side of the top of the bottom plate. The top of the base is fixedly connected to an opening Mold mechanism; the mold opening mechanism includes a fixed plate and a top plate, and the bottom of the fixed plate is fixedly connected with the top of the base, the top of the fixed plate is fixedly connected with a lower mold, and the bottom of the top plate is fixedly connected with an upper mold. The present invention relates to the field of hydraulic machinery technology . The unilateral tearing and micro-opening device of the FRP forming hydraulic press can realize that when the FRP needs to be mold-opened during solidification and molding, the first hydraulic cylinder can be used to slightly open the unilateral side of the upper mold, so that the upper mold can be opened on the top. When lifting, a crack is torn open to allow outside air to enter the mold, and then the upper mold is controlled by the second hydraulic cylinder to open upward, reducing the pressure of the second hydraulic cylinder to lift upward and open the mold quickly.

Description

technical field [0001] The invention relates to the technical field of hydraulic machinery, in particular to a micro-opening device for unilateral tearing of a glass fiber reinforced plastic forming hydraulic press. Background technique [0002] FRP is also called GFRP, that is, fiber reinforced plastics, which generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as reinforced plastics, called glass fiber reinforced plastics, Or called FRP, which is different from tempered glass. Because of the different types of resin used, there are polyester FRP, epoxy FRP, and phenolic FRP. It is light and hard, non-conductive, stable in performance, high in mechanical strength, and recyclable. Less, corrosion-resistant, can replace steel to manufacture machine parts and automobile, ship shells, etc. [0003] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pasca...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a single-side tearing micro-opening device for a glass fiber reinforced plastic forming hydraulic press, which solves the problem that the temperature rise, resin flow and exhaust process of the glass fiber reinforced plastic product cause the inside of the mold to be damaged. It is in a vacuum state, and it is difficult to open the mold, which causes a lot of pressure on the hydraulic mechanism and easily causes damage to the hydraulic mechanism and the mold.
