Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1 to 3, an embodiment of the present utility model: the extrusion molding equipment comprises a base 1 and an upper seat 2, wherein a groove 11 is formed in the base 1, a die seat 3 is arranged in the groove 11, a buffer mechanism 8 is arranged between the die seat 3 and the groove 11, the buffer mechanism 8 comprises a connecting block and a spring, a die plate 4 is arranged in the die seat 3, a molding groove 41 is formed in the die plate 4, 4 guide posts 5 are arranged between the base 1 and the upper seat 2, a hydraulic cylinder 10 is arranged above the upper seat 2, 2 telescopic machines 6 are arranged below the upper seat 2, the hydraulic cylinder 10 is connected with the telescopic machines 6, the telescopic machines 6 are controlled to stretch through the hydraulic cylinder 10, and an extrusion plate 7 is connected below the telescopic machines 6.

The working principle of the utility model is as follows: after the hydraulic cylinder 10 is electrified to work, the telescopic machine 6 stretches out to push the extrusion plate 7 to move downwards, after the extrusion plate 7 contacts a workpiece, the die plate 4 and the die seat 3 for installing the workpiece are pushed to move downwards, and the buffer device absorbs the pressure brought by the extrusion plate 7, so that the workpiece is not deformed severely in the downward movement process of the die seat 3, the generation of splashing scraps is prevented, after the downward movement stroke is finished, the workpiece deforms in the groove 11 of the base 1, and an operator is not injured even if the splashing scraps are generated.

Further explained, as shown in fig. 1 and 2, the guide post 5 passes through the pressing plate 7, and the pressing plate 7 is slidably connected with the guide post 5. Through sliding connection, the guide post 5 is convenient for the removal of stripper plate 7 during operation between stripper plate 7, leads the motion track of stripper plate 7 simultaneously, guarantees to keep parallelism with between the mould seat 3, guarantees the quality of processing work piece.

As shown in fig. 2, the height of the die holder 3 is smaller than the depth of the groove 11, and the upper surface of the die holder 3 is flush with the upper surface of the base 1. This results in a cavity between the mould base 3 and the recess 11, ensuring that the mould base 3 has a sufficient stroke during operation, while providing sufficient working space for the cushioning mechanism 8.

As shown in fig. 2, the buffer mechanism 8 is installed in an installation hole 111 formed at the bottom of the groove 11, and the upper end of the buffer mechanism 8 is connected to the bottom of the mold base 3.
