Glass steel forming hydraulic machine single-side tearing micro die sinking device

Abstract

The invention discloses a glass steel forming hydraulic machine single-side tearing micro die sinking device, and relates to the technical field of hydraulic machines. 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 are included, and a die sinking mechanism is fixedly connectedto the top of the base. The die sinking mechanism comprises a fixing plate and a top plate. The bottom of the fixing plate is fixedly connected with the top of the base. The top of the fixing plate isfixedly connected with a lower die. The bottom of the top plate is fixedly connected with an upper die. By means of the glass steel forming hydraulic machine single-side tearing micro die sinking device, when glass steel needs to be subjected to die sinking during curing forming, the single side of the upper die can be subjected to micro die sinking through jacking of a first hydraulic cylinder,a crack is formed in the upper die through tearing during jacking, outside air enters the die, then, a second hydraulic cylinder is used for controlling the upper die for upward die sinking, the upward jacking pressure of the second hydraulic cylinder is reduced, and rapid die sinking is achieved.

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.
