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...

Embodiment Construction

[0014] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0015] Such as figure 1 As shown, the sand mold vibration device in the V method casting in the V method casting of the present invention includes a positioning pin 5, a vibration table 1, a vibration base 2, an air spring 4, a guide rod 7, a hydraulic cylinder 9, and a support frame 6. Lateral vibration motor 3 and up and down vibration motor 8.

[0016] The positioning pins are arranged on the upper surface of the vibrating table. The positioning pin is used to fix the sand box or the pumping chamber of the sand box, and is positioned by cooperating with the positioning pin sleeve at the bottom of the sand box or the bottom of the pumping chamber of the sand box, thereby fixing the sand box or the pumping chamber of the sand box.

[0017] The bottom four corners of the vibrating table are respectively connected to the vibrating base through air spri...
