AI Technical Summary

Technical Problem

Traditional rectifier bridge mold frames are integrated structures, resulting in high maintenance costs. Once the mold cavity or inserts are worn, the entire structure needs to be replaced, which is inefficient, time-consuming, and labor-intensive, and requires multiple people to work together.

Method used

A detachable mold frame consisting of a lower mold frame and an upper mold frame was designed. By setting up structures such as docking grooves, telescopic rods, rollers, snap-fit ​​blocks, limit rods and pins, the mold frame can be easily disassembled and installed, reducing the reliance on tools and manpower.

Benefits of technology

It improves the efficiency and convenience of mold frame disassembly, reduces maintenance costs, and minimizes downtime and manpower requirements.

Abstract

This utility model relates to the field of rectifier bridge technology, and more particularly to a detachable mold frame for a rectifier bridge. The technical solution includes: a lower mold frame and an upper mold frame. Multiple mating slots are provided on the front side of both the lower and upper mold frames. Each mating slot has a telescopic rod on its left and right inner walls. A spring is fitted around the outer ring of each telescopic rod. Rollers are provided at the ends of two telescopic rods that are close to each other. A common locking block engages between the two rollers. A U-shaped sheath is provided on the rear side of the locking block. Two movable slots are provided on the right side of the lower mold frame, and a receiving slot is provided on the left side of each movable slot. This utility model facilitates the removal of the U-shaped sheath from the lower or upper mold frame by setting the mating slots to the locking block, without the need for tools or excessive manpower, thus providing convenience. The setting of a limiting rod to the pin facilitates the disassembly and installation of the lower and upper mold frames without the need for tools, further improving convenience.
