Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, and in particular to a hydraulic casting machine. Background Art

[0002] A hydraulic press is a machine that uses the hydrostatic pressure of a liquid as the working medium and is made according to Pascal's principle to transfer energy for processing products such as metals, plastics, rubbers, woods, powders, etc. A hydraulic press generally consists of three parts: the machine itself, the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

[0003] In the prior art, for example, a hydraulic press with the publication number CN206579185U restricts the movement of the limit rod by setting a guide rail on the machine body. Since the limit rod is fixedly connected to the pressure plate, it can guide the pressure plate and improve the anti-eccentric load performance of the pressure plate. This solution changes the complex cooperation between four guide columns and oil copper sleeves into the cooperation between a single straight guide rail and the limit rod. While achieving the guiding effect, it reduces the assembly difficulty and makes it easy to adjust the matching precision between the sliding component and the straight guide rail. However, in this solution, after the hydraulic press performs hydraulic shaping on mechanical parts, when adjusting the placement angle of the mechanical parts, it is usually manually operated by the staff. At this time, the surface of the unshaped mechanical parts may be irregular and relatively sharp, which is likely to cause scratches to the staff. Summary of the Utility Model

By setting a limiting arm, the limiting and clamping of the parts are realized, avoiding the situation of the parts shifting or even falling off during the extrusion process, which is beneficial to ensuring the stability of the parts during processing and improving the processing efficiency.
