Description

Technical Field

[0001] The utility model relates to the technical field of pressing moulds, in particular to a pressing mould for moisture-proof and heat-insulating materials. Background Art

[0002] The pressing mold is a device used to press and form the blank during the manufacturing process of moisture-proof and thermal insulation materials. However, the existing pressing mold still has shortcomings. Specifically, when the existing pressing mold presses the blank, the air inside the pressing mold after closing is squeezed out by the blank, resulting in a large pressure difference between the inside and outside of the mold, making it difficult to open the pressing mold.

[0003] Therefore, a pressing mold for moisture-proof and heat-insulating materials is needed to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a pressing die for moisture-proof and heat-insulating materials to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A pressing mold for moisture-proof and heat-insulating materials, comprising an upper mold, an outer wall of the upper mold being provided with an opening and closing mechanism, and a lower mold being provided at the bottom of the upper mold;

[0007] The cam is fixedly connected to the outer wall of the upper mold and is fixedly connected to the fixed plate below the push plate. The opening and closing plate is slidably connected inside the fixed plate. The outer wall of the fixed plate is fixedly connected to a liquid reservoir below the opening and closing plate. A guide tube is fixedly connected above the center of the inner wall of the liquid reservoir and near the fixed plate. A return tube is fixedly connected below the center of the inner wall of the liquid reservoir and near the fixed plate. An adjusting shaft is rotatably connected inside the return tube. The outer wall of the adjusting shaft is fixedly connected to a gate plate inside the return tube. A volute spring is fixedly connected to the outer wall of the adjusting shaft and below the gate plate. A piston plate is slidably connected inside the liquid reservoir and at a position away from the fixed plate. A drive shaft is rotatably connected inside the liquid reservoir and near the piston plate. The outer wall of the drive shaft is fixedly connected to a push cam inside the liquid reservoir. The outer wall of the piston plate is fixedly connected to a return spring near the drive shaft. A one-way valve is fixedly connected inside the guide tube.

[0008] As a preferred solution of the present invention, the opening and closing mechanisms are provided in two groups, and the two groups of opening and closing mechanisms are symmetrically arranged on both sides of the upper mold.

[0009] As a preferred solution of the present invention, the push plate, fixed plate, liquid storage cylinder and push cam are all made of stainless steel, the opening and closing plate is an I-shaped structure design, and the connection method of the spiral spring, return spring and liquid storage cylinder is a fixed connection.

[0010] As a preferred solution of the present invention, the gate plate and the piston plate are both made of silicone, the adjusting shaft passes through the reflux pipe and extends outside the liquid storage cylinder, and the connection between the gate plate and the reflux pipe and the pushing cam and the piston plate are all sliding connections.

[0011] As a preferred solution of the present invention, the opening and closing plate passes through and extends outside the fixed plate, hydraulic oil is stored in both the liquid storage cylinder and the fixed plate, and the drive shaft passes through and extends outside the liquid storage cylinder.

[0012] As a preferred solution of the present invention, the one-way valve only allows the fluid to flow out of the guide tube, and the guide tube and the return tube both pass through the liquid storage cylinder and extend into the fixed plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the utility model, a pressing mold for moisture-proof and thermal insulation materials is designed, and the opening and closing mechanism in the device is used to open the upper and lower molds, and the raw materials are placed in the lower mold. Then, the upper mold is covered on the lower mold, and pressure is applied to the top of the upper mold. The upper and lower molds press the raw materials under the action of external pressure. After the pressing is completed, the pressure applied to the top of the upper mold is removed, and the driving shaft is rotated. The driving shaft drives the push cam to rotate, and the rotating push cam drives the piston plate to move. The moving piston plate pushes the hydraulic oil in the liquid storage cylinder into the fixed plate. The driving shaft drives the push cam to continue to rotate, and the continuously rotating push cam will disengage the piston. The return spring will pull the piston plate to move in the opposite direction, and the piston plate that moves in the opposite direction returns to its original position. The piston plate moves back and forth in the horizontal direction under the push of the rotating push cam and the return spring, thereby continuously injecting the hydraulic oil in the liquid reservoir into the fixed plate. The hydraulic oil entering the fixed plate will push the opening and closing plate to move upward, and the upward-moving opening and closing plate will drive the upper mold to move upward through the push plate, so that the upper mold is separated from the lower mold, and it is more convenient to separate the upper mold and the lower mold, which solves the problem that when the existing pressing mold is pressed together, the air inside the pressing mold after closing is squeezed out by the blank, resulting in a large pressure difference between the inside and outside of the mold, making it difficult to open the pressing mold.
