Description

Technical Field

[0001] This utility model relates to the field of die casting technology for hydraulic presses, and in particular to a die casting extrusion and trimming device for hydraulic presses. Background Technology

[0002] Die casting is a type of pressure-cast part. It involves using a pressure casting machine equipped with a casting mold. Molten copper, zinc, aluminum, or alloys are poured into the machine's feed inlet, and the casting process produces copper, zinc, aluminum, or alloy parts of the shape and size specified by the mold. Because die casting materials are non-ferrous metals with high fluidity and plasticity, various burrs and flashes appear during the die casting process, requiring removal. Therefore, a hydraulic press-type die casting extrusion and trimming device is needed.

[0003] When using a hydraulic press die casting extrusion trimming device, the existing cutting structure can generally only cut at one angle, making it difficult to trim multi-angle burrs on the same device. Furthermore, when the cutting structure cuts burrs, random cutting can easily damage the die casting. Utility Model Content

[0004] The purpose of this utility model is to provide a die-casting extrusion and trimming device for hydraulic presses, which enables the device to trim edges at different angles by means of the first and second push balls swinging the base and the upper structure, so that the die-casting body will not be damaged by trimming.

[0005] To achieve the above objectives, a die-casting extrusion and trimming device for a hydraulic press is provided, comprising a base, a swing ball fixedly connected to the lower end of the base, a first pushing ball and a second pushing ball correspondingly arranged on both sides of the swing ball, a first electric push rod fixedly connected to the lower end of the first and second pushing balls, a fixed seat fixedly connected to the lower end of the first electric push rod, a support frame fixedly connected to the upper end of the base, a movable seat correspondingly arranged on one side of the support frame, an extension plate slidably connected to the inner side of the movable seat, a motor arranged on one side of the extension plate, two third electric push rods symmetrically fixedly connected to the other side of the extension plate, the third electric push rods fixedly connected to the inner wall of the movable seat, a cutting blade arranged on one side of the motor, a bearing arranged on one side of the cutting blade, and a protrusion fixedly connected to one side of the bearing.
