Improved impact head for shock absorber of aluminum die casting spraying machine

Abstract

An improved impact head for a shock absorber of an aluminum die casting spraying machine comprises a bracket mounting base of the aluminum die casting spraying machine, wherein the bracket mounting base is connected with a spraying case base and a spraying machine assembly; the spraying machine assembly is connected with a spraying pipe and a power bracket; the power bracket is driven by an air cylinder and is connected with one end of a long lateral arm and one end of a short lateral arm; the other ends of the long lateral arm and the short lateral arm are connected onto the spraying case base through rotating shafts; the shock absorber is mounted below the spraying case base and comprises a machine body bracket and a shock absorber main body mounted on the machine body bracket; a bufferrod is arranged in the shock absorber main body; the head of the buffer rod is connected with an impact cap; and a spring is mounted between the impact cap and the shock absorber main body. The improved impact head is characterized in that bearings are mounted on the long lateral arm and the short lateral arm and are contacted with an upper plane of the impact cap.

Description

technical field [0001] The invention relates to an improved bumper for a shock absorber of an aluminum die-casting mold sprayer, and belongs to the field of metal casting. Background technique [0002] Aluminum die-casting is one of the commonly used processing methods for aluminum products. Whenever die-casting is processed, it is first necessary to spray a release agent on the surface of the mold cavity in the state of mold opening to ensure good release of the product after die-casting. Existing spray release agents include artificial spraying and spraying machine spraying. Artificial spraying has the disadvantages of troublesome operation, spraying liquid in the form of raindrops, large waste of raw materials, and unevenness; The pipeline of compressed air and release agent passes through the single-chip computer PC automatic control system, and the water and air are atomized by pressure, and then the die-casting release agent is sucked in, and the pressure-atomized wate...

Problems solved by technology

The meeting head of prior art is the cam that is made one with short left and right arms, as image 3 As shown, when working, one end of the short left and right arms 8 is driven by the cylinder to run along with the power bracket and moves in an arc around the rotating shaft 4 installed on the base 1 of the die-casting sprayer box. The force is very large under the push of the cylinder. The cam 82 not only has a large impact, but also impacts the impact cap 75 on the buffer rod of the shock absorber 7 in an arc shape. Fast wear and tear, and the buffer rod 73 is bent and broken, and the service life of the entire shock absorber is short, which not only increases maintenance costs, but also affects work efficiency during shutdown maintenance
