A centrifugal casting pipe mold end cover bracket

Abstract

The invention discloses a centrifugal cast pipe mold end cover bracket. The end cover bracket comprises a bracket body, and one end surface of the bracket body is provided with two installation grooves and two kidney-shaped holes; each installation groove comprises a main groove, a first side groove and a second side groove, the main groove is located between the first side groove and the second side groove, the first side groove and the second side groove are symmetrical, a first installation hole is formed between the main groove and the first side groove, and a second installation hole is formed between the main groove and the second side groove; the kidney-shaped holes are located between the two installation grooves and provided with kidney-shaped plates; the other end surface of thebracket body is internally provided with an installation step, the bottom end of the installation step is provided with a clamping groove, third screw holes are uniformly formed in the top end of theinstallation step, the installation step is closely matched with a cast pipe mold, and the end cover bracket is fixed to the cast pipe mold by the third screw holes through bolts. The end cover bracket can be repeatedly utilized and convenient to disassemble and can automatically lock the end cover when the mold stops and achieve automatic clamping.

Description

technical field [0001] The invention belongs to the field of component manufacturing, and in particular relates to a centrifugal casting pipe mold end cover bracket. Background technique [0002] During the production of centrifugal cast pipe, end caps need to be installed at both ends of the mold to seal the molten iron so that the molten iron solidifies in the mold to form a cast pipe. [0003] Generally, pins are used to manually lock the end cap or fly hammer to automatically lock the end cap, and the end cap bracket and the end face of the mold cooperate to block the molten iron. Generally, a groove is directly processed on the end surface of the mold to fix the end cover. When the end surface runs out of iron, the mating surface is often burned, and the mold repair is very troublesome. Even the mold is directly scrapped, resulting in unnecessary waste. [0004] When installing the end cover of the pin type, you need to use a hammer to knock three pins into the oblique...

AI Technical Summary

Problems solved by technology

After spraying, once the mold stops rotating, the flyweight will lose centrifugal force and cannot press the end cap, causing the end cap to loosen, and the paint at the joint between the end face of the end cap and the end face of the mold will collapse and fall off, and the falling paint will fall into the end when the mold rotates again. The sealing between the cover and the mold fails, and the molten iron splashes along the gap to the outer circumference during casting, causing running iron, which affects product quality and poses a safety hazard (high temperature molten iron is easy to burn the operator)
