Hot core box automatic mold splitting device

Abstract

The invention relates to an automatic mold splitting device for hot-core boxes. A first lifting execution component arranged on a fixed base is connected with a first guide-rail cross beam, a first upper connecting component connected to the first guide-rail cross beam is slidably connected with a first lower connecting component, two positioning plates are arranged on the first guide-rail cross beam and can be transversely adjusted; a second lifting execution component arranged on a baseplate of a movable seat is connected with a second guide-rail cross beam, a second upper connecting component connected to the second guide-rail cross beam is slidably connected with a second lower connecting component, two movable positioning plates are arranged on the second guide-rail cross beam and can be transversely adjusted, a horizontal sliding retracted execution component arranged on a supporting seat is connected with a pushing top plate, the pushing top plate is connected with the movable seat through a connecting rod, and a limited connecting rod is arranged in a limiting groove of the pushing top plate and connected with the second guide-rail cross beam. The automatic mold splitting device for hot-core boxes disclosed by the invention is reasonable in structure, and can carry out fast separation and installation on movable and stationary dies of core boxes, and ensure that an internal structure of a core box is not collided; the automatic mold splitting device for hot-core boxes is convenient to operate and high in universality, and can improve the efficiency of maintenance.

Description

technical field [0001] The invention relates to an automatic mold splitting device for a hot core box, which belongs to the technical field of foundry core making. Background technique [0002] The hot core box core making technology is to inject the sand material mixed with foundry sand, thermosetting resin and catalyst into the core box with a heating device, so that the sand material close to the surface of the core box is heated, so that the binder is ready in a short time. It can be polycondensed and hardened to form a core, which has the advantages of shortening the production cycle and is especially suitable for the rapid production of medium and small sand cores with high dimensional accuracy. [0003] The moving mold and the fixed mold of the core box are made of metal materials. Due to the heavy weight, when cleaning and maintaining the inner cavity, one is to separate the moving mold and the fixed mold of the core box directly in the core shooter. , Carry out cle...

Problems solved by technology

[0003] The moving mold and the fixed mold of the core box are made of metal materials. Due to the heavy weight, when cleaning and maintaining the inner cavity, one is to separate the moving mold and the fixed mold of the core box directly in the core shooter. , cleaning and maintenance work on the core shooter, which will seriously affect the production efficiency of the core shooter

The other way is to separate the movable mold and fixed mold of the core box after the core shooter, and hoist the separated movable mold and fixed mold to the line by driving, and clean the inner cavity of the movable mold and the fixed mold. For maintenance and repair work, after the work is completed, it will be hoisted to the core shooter for mold clamping by driving. This method will also occupy the core shooter and affect its production efficiency. Hoisting increases the auxiliary time of hoisting, and the inner cavity will be bumped during the hoisting process, which may damage the inner cavity structure of the core box

At present, most of the hot core boxes are hoisted to the offline for maintenance and maintenance. Although this method does not affect the production efficiency of the core shooter, it is necessary to turn the core box 90° first, and then hoist the starting mold with the crane again. Not only does it require two operators to separate the movable mold and the fixed mold of the core box, but also it is easy to cause bumps in the inner cavity during the turning and lifting process, which will affect the inner shape of the core box and the positioning device. It will cause damage, and at the same time, it is not convenient to check the inner cavity of the core box and change the internal structure of the core box. It takes a lot of manpower and material resources to disassemble and assemble the core box offline, resulting in low maintenance efficiency of the core box
