Brick press die sleeve

Abstract

The invention provides a brick press die sleeve which is reasonable in structure and low in machining difficulty. The brick press die sleeve is composed of two end die sleeve bodies (1), a middle die sleeve body (2) and six sets of fastening bolts and nuts (6) and is characterized in that the middle die sleeve body (2) is clamped between the two end die sleeve bodies (1), and the middle die sleeve body (2) and the two end die sleeve bodies (1) are fastened into a whole through the six sets of fastening bolts and nuts (6); fabrication holes (3) are formed in the four square corners of a die sleeve central cavity (4), and the brick press die sleeve is provided with six through holes (5); and counter bores (11) are formed in the two end faces of each through hole (5). The brick press die sleeve has the advantages that the machining difficulty is low, the service life is long, and meanwhile according to the abrasion conditions of the three die sleeve bodies, one of the three die sleeve bodies can be replaced at any time, so that all production cost of an industrial chain is greatly reduced, and more economy benefits can be saved for social creation.

Description

technical field [0001] The invention relates to a mold, in particular to a mold cover for a brick press in the refractory material industry. Background technique [0002] At present, the mold sets used by the brick press have serious structural defects. The main accident phenomenon is as follows: cracks at the opposite corners of the mold sets, and the service life of a set of mold sets is extremely short. Some even installed a few bricks. The die sets are cracked. [0003] Dimensions of mold cover are: 1 meter in length, 0.6 meters in width, and 0.3 meters in height. The cost of a set is at least 70,000 yuan, and it has a serious impact on production. Improving the service life of mold sets and improving the quality of mold sets are the most urgent tasks for refractory enterprises. However, various enterprises have no obvious effect on the improvement of the mold sleeve, the service life of the mold sleeve is still very short, and the phenomenon of diagonal cracking has ...

AI Technical Summary

Problems solved by technology

[0004] The main reasons for the cracking of the mold sleeve are: 1. The outer dimension of the mold sleeve is too large, and the blank itself has defects such as casting sand holes and pores before processing (the minimum size of the blank is 350mm in thickness, 1050mm in length, and 650mm in width); 2. The size of the mold sleeve is large, and it is difficult to heat treatment after processing. The main performance is that the heat treatment is uneven, or it is far from meeting the technical requirements, resulting in stress concentration, which makes the mold sleeve easy to crack.
