Opening and closing device for radial extrusion die

Abstract

The invention relates to an opening and closing device for a radial extrusion die. The extrusion die comprises a fixed die sheet and a movable die sheet matched with the fixed die plate, and a protruding plate for connection is arranged at the joint between the fixed die sheet and the movable die sheet; a plurality of connecting plates arranged in the longitudinal direction are fixedly connected to the side surface of the fixed die sheet and are located on the same longitudinal straight line, and one side of each connecting plate is clamped on the side, located on the fixed die sheet, of the protruding plate; a connecting rod is arranged for penetrating through the connecting plates and can rotate relative to the connecting plates; the connecting rod is fixedly provided with a plurality of rotating plates moving along with the connecting rod, and the rotating plates can move to be clamped on the side, located on the movable die sheet, of the protruding plate. According to the device, by arranging the protruding plate, the connecting plates, the connecting rod and the rotating plates, the die can be fast and conveniently closed and opened, the structure is simple, and use is convenient and reliable.

Description

technical field [0001] The invention relates to a radial extrusion mold opening and closing device, which belongs to the technical field of concrete and reinforced concrete pipe production equipment. Background technique [0002] The existing concrete pipe molds of radial extrusion molding process all use manpower to open and close the molds. Due to the high height of the extrusion molds, in order to lock the doors reliably, generally multiple door locks are set in the longitudinal direction of the extrusion molds. During manual operation, it is necessary to lock the door locks one by one, the work intensity is very high, and some auxiliary equipment is needed to lock those door locks at higher positions, so the efficiency is also very low; at the same time, it is necessary to open the door locks Corresponding operations must be carried out at the same time, so in the actual use process, this manual method is very inconvenient and needs to be improved urgently.

Problems solved by technology

[0002] The existing radial extrusion molding process concrete pipe molds all use manpower to open and close the mold. Since the extrusion mold is high in height, in order to lock the door reliably, generally a plurality of door locks are set in the longitudinal direction of the extrusion mold, so the During manual operation, it is necessary to lock the door locks one by one, the work intensity is very high, and it is necessary to use some auxiliary equipment to lock those door locks at a higher position, so the efficiency is also very low; at the same time, it is necessary to open the door lock Corresponding operations must also be carried out, so in the actual use process, this manual method is very inconvenient and needs to be improved urgently.
