Sand mold compacting device for V-process casting

Abstract

The invention discloses a sand mold compacting device for V-process casting and aims to provide a sand mold compacting device with more stable lifting capacity and better sand mold compacting effect for the V-process casting. The sand mold compacting device for the V-process casting is characterized by comprising positioning pins, a compacting table board, a compacting base, air springs, guide rods, a hydraulic cylinder, a support bracket, lateral vibration motors and vertical vibration motors, wherein four corners of the bottom of the compacting table board are connected onto the compacting base through the air springs respectively; the bottom of the compacting base is connected onto the support bracket through the guide rods and the hydraulic cylinder; the lower ends of the guide rods are connected to guide pipes of the support bracket in a sleeving manner respectively and extend out of the bottom ends of the guide pipes; the upper end of a barrel of the hydraulic cylinder is fixedly connected to the center of the support bracket; the lateral vibration motors are fixedly connected to the sides of the compacting table board; the vertical vibration motors are fixedly connected to the bottom ends of the guide rods respectively.

Description

technical field [0001] The invention relates to a V-method casting device, in particular to a sand mold vibrating device in the V-method casting. Background technique [0002] V method casting, also known as vacuum sealing molding, is named after the prefix "V" of the English word Vacuum (vacuum). The biggest advantage it differs from traditional sand casting is that it does not use adhesives. V-method casting uses plastic film to seal the sand box, and the air in the mold is drawn out by a vacuum pumping system. There is a pressure difference between the inside and outside of the mold, making the dry sand dense and forming The required mold cavity is solidified by setting the core, closing the box, pouring and evacuating the casting, and the negative pressure is released, and the molding sand is then collapsed to obtain the casting. [0003] Dry sand molding without any binder is used in V-method casting, but dry sand has no adhesive force, so to achieve high enough mold s...

Problems solved by technology

However, only relying on the air spring structure on the traditional vibrating table, due to the stretching elasticity, it is difficult to ensure the height of the vibrating table and the stability of the raised table, resulting in the lack of sealing between the sand box and the sanding device, and the sanding effect is not good. ideal
