Optimized hydraulic system

1. The optimized hydraulic system can realize the function of double-sided compaction, which improves the disadvantage of uneven hardness on both sides of sand mold caused by single-sided compaction, and improves the product quality and qualification rate. 2. The optimized hydraulic system can realize the function of drawing the mold outside the cavity, which avoids the formation of vacuum damage to the sand mold when the reverse pressure plate is opened, which is conducive to the demoulding of the product. The optimized hydraulic system makes the closing more gentle, and only needs to input the mold parameters correctly to ensure that the closing will not have the phenomenon of collision and slit. 3. The optimized hydraulic system makes the power of the whole machine light rain 60KW, which is nearly 20KW less than that of the same industry products, reducing the user's equipment use cost and system design.

Definition and construction of steel wire rope

The steel wire rope is a flexible rope twisted by multiple or multiple strands of thin steel wire. The steel wire rope is twisted by multiple layers of steel wire into strands, and then twisted by a certain number of strands into a spiral rope with the core as the center. In material handling machinery, for lifting, pulling, tensioning, and carrying purposes. The wire rope has high strength, light weight, stable work, not easy to break the whole wire suddenly, and reliable work. The steel wire rope plays the role of bearing load, and its performance is mainly determined by the steel wire. Steel wire is a round (or special-shaped) wire made of carbon steel or alloy steel by cold drawing or cold rolling. It has high strength and toughness, and is used according to different environmental conditions.

Overview of elevator guide rails

The elevator guide rail is the safety rail for the elevator to travel up and down the hoistway. The guide rail is installed on the hoistway wall and is fixedly connected to the hoistway wall by the guide rail frame and the guide rail bracket. Elevator commonly used guide rail is "T" type guide rail. Strong rigidity, high reliability, safe and cheap. The guide rail plane shall be smooth without obvious uneven surface. Since the guide rail is the shuttle rail of the guide shoe and safety gear on the elevator car, the clearance must be ensured during installation. At the same time, the guide rail has to bear the responsibility of stopping the elevator when the elevator overspeed accident occurs, so its rigidity cannot be ignored. Elevator guide rail is installed in the elevator shaft or between the floor of two or more vertical or inclined rigid track, to ensure that the car and the counterweight along its up and down movement, to ensure that the escalator and automatic sidewalk steps along its tilt or horizontal movement, for the elevator car, counterweight device or ladder to provide guidance. From the definition of guide rail, guide rail is an important reference component of vertical elevator, automatic elevator and automatic sidewalk step. It controls the elevator car, escalator and automatic sidewalk step track, ensures the transmission of operation signal, and it is also an important part related to elevator safety and operation quality.
