Problems solved by technology

[0005] The purpose of the present invention is to provide a method and device for green mold sand casting of automobile hydraulic cylinders, aiming to solve the problem that the green sand molds of automobile hydraulic cylinders in the prior art cannot be lifted during the production and casting process. , so that there is no good pre-tightening force between the upper and lower molds of the hydraulic cylinder, resulting in the casting of the hydraulic cylinder that does not meet the standards, which in turn leads to technical problems with a low product qualification rate

Abstract

The invention relates to the technical field of hydraulic cylinder green sand casting, in particular to an automobile hydraulic cylinder green sand casting method and device. Green sand needing to be cast is poured into an upper mold, when the green sand needs to be cast, an operator holds a handle to rotate, then a rotating rod is driven to rotate, a gear is driven to rotate in a support, a lead screw on the side edge is driven to move up and down, and a supporting plate is driven to move up and down; when the lead screw drives the supporting plate to move upwards, the upper mold is driven to move towards a pressing assembly; and an air cylinder is started to drive an extension rod to move a moving plate, so that a lower mold is driven to press the upper mold on the supporting plate, the pre-tightening force of an upper mold plate and a lower mold plate can be enhanced, and the product percent of pass is increased.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinder castings, in particular to a green mold sand casting method and device for an automobile hydraulic cylinder. Background technique [0002] Green mold sand, also known as green mold sand, refers to the sand mixed with bentonite as a binder in foundry production, then mixed with water and other additives, which can be used for molding and core making. The sand mold (core) does not need to be dried and can be poured directly. . [0003] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. [0004] During the production and ca...
