Embodiment Construction

[0012] The specific implementation of the present invention will be described in detail below in conjunction with the drawings and preferred embodiments. Such as figure 1 As shown, a large-scale valve sleeve mold unloading device includes a frame 1, a first hydraulic cylinder 2, a second hydraulic cylinder 3, and a mold support seat 4. The first hydraulic cylinder and the second hydraulic cylinder are respectively fixed on the On the upper part of the frame, the piston rods of the first hydraulic cylinder and the second hydraulic cylinder are connected to the connecting plate 5, and the lower part of the connecting plate is connected with a pressure plate 6; the mold support seat is arranged below the pressure plate, so The lower part of the mold support seat is provided with a roller 7, and the upper part of the mold support seat is provided with a mold support block 8. Compared with the prior art, this device uses two hydraulic cylinders to drive the pressure plate to move, ...

Abstract

The invention relates to the technical field of valve manufacturing, in particular to a demolding device for a large-scale valve bush. The demolding device for the large-scale valve bush comprises a machine frame, a first hydraulic oil cylinder, a second hydraulic oil cylinder and a mold supporting seat. The first hydraulic oil cylinder and the second hydraulic oil cylinder are fixed to the upper portion of the machine frame. A piston rod of the first hydraulic oil cylinder and a piston rod of the second hydraulic oil cylinder are connected with a connecting plate. A pressing plate is connected to the lower portion of the connecting plate. The mold supporting seat is arranged below the pressing plate. Rolling wheels are arranged on the lower portion of the mold supporting seat. Mold supporting blocks are arranged on the upper portion of the mold supporting seat. Compared with the prior art, the demolding device for the large-scale valve bush lifts a mold on the mold supporting seat in the manner that the two hydraulic oil cylinders drive the pressing plate to move and moves the mold to the position below the hydraulic oil cylinders through the rolling wheels, the hydraulic oil cylinders drive the pressing plate to move downwards to press the edge of the mold after the hydraulic oil cylinders are started, the mold can be separated from a rubber bush when the pressing plate continues to press the mold downwards, the situation that workers hit the mold to achieve demolding is avoided, and therefore the demolding device for the large-scale valve bush improves work efficiency.

Description

Technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a large valve sleeve mold unloading device. Background technique [0002] As we all know, in the field of valve seat manufacturing, one of the rubber molding methods is injection vulcanization molding. In this molding method, the refined rubber material needs to be cut into long strips in advance, and then the long rubber material is injected into the molding die by heating and extrusion to implement vulcanization molding. This injection-type vulcanization molding method can reduce defects and bubbles on rubber products and improve the yield rate. [0003] It is very difficult to separate the vulcanized mold from the internal rubber, especially the large valve seat, which is difficult to separate from the mold after vulcanization. Workers often need to hold a hammer to tap slowly to separate the valve seat from the mold. The work efficiency is low and the labor intensity i...
