Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, in particular to a mold with an inclined ejector rod slide seat structure. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by injection moulding, blow moulding, extrusion, die casting or forging, smelting, stamping and other methods. They are tools used to make moulded objects, among which the demolding device is an important part of the mould.

[0003] Existing molds are composed of various parts, and different molds are composed of different parts. When using the mold to make a model, after the mold is closed and cooled, demolding is required, and usually a ejector plate is used for demolding.

At the same time, high temperature is generated during injection molding, and the thermal expansion and contraction of the ejector pin will cause the demolding device to be locked and unable to demold. Therefore, a mold with an inclined ejector pin slide structure is proposed to solve the above problems. Utility Model Content

By setting a cooling pipe for the inclined ejector pin, the water pump circulates the cooling water in the cooling pipe, which effectively prevents the inclined ejector pin from being locked due to thermal expansion and contraction and affects the processing progress.

During operation, in order to prevent high temperature of injection molding, This causes the inclined ejector rod 5 to expand and lock in the ejector rod sliding hole 4, resulting in the problem of being unable to be demolded. When the injection molding work starts, the water pump 21 is started, and the cooling water in the cooling water tank 22 is pumped into the drain pipe 24 through the suction pipe 23, and then enters the cooling pipe 20 in the inclined ejector rod 5 to cool the inclined ejector rod 5. The cooling water passes through the cooling pipe 20 and enters the outlet pipe 25 to reach the cooling water tank 22, so that the cooling water circulates and cools the inclined ejector rod 5. By setting the cooling pipe 20 for the inclined ejector rod 5, the water pump 21 circulates the cooling water in the cooling pipe 20, which effectively prevents the inclined ejector rod 5 from being locked due to thermal expansion and contraction and affects the processing progress.

[0031] Working principle: After mold closing, injection molding is required. The injection molding material is added into the injection molding tank 26 through the feed hopper 28, the heating ring 29 is started to melt the injection molding material, and then the cylinder 30 is started. The insert rod 31 pushes the extrusion disk 32 to squeeze the melted injection molding material into the mold cavity 7 through the injection molding tube 27 for injection molding; in order to improve the demolding efficiency of the mold, after the injection molding work is completed and the model is cooled, the demolding operation needs to be performed. The servo motor 14 is started, and the screw 13 rotates to make the moving block 10 drive the mold seat 2 to move horizontally. When the top plate 9 contacts the roller 17 on the V-shaped fixed block 16, the top plate 9 slides on the roller 17, and the mold seat 2 continues to move so that the inclined ejector 5 drives the mold 6 to leave the mold groove 3 and expand outward, so that the mold cavity 7 is opened, and the internal molding model falls off to complete the demolding operation.

The cooling water enters the outlet pipe 25 after passing through the cooling pipe 20 and reaches the cooling water tank 22, so that the cooling water circulates and cools the inclined ejector rod 5. By setting the cooling pipe 20 for the inclined ejector rod 5, the water pump 21 circulates the cooling water in the cooling pipe 20, effectively preventing the inclined ejector rod 5 from being locked due to thermal expansion and contraction and affecting the processing progress.
