Mold opening and closing mechanism

Abstract

The invention discloses a mold opening and closing mechanism. The mold opening and closing mechanism mainly comprises a combined mold and a driving mechanism. When a rotary driving mode is adopted, a motor drives a lead screw to rotate through a reversing apparatus and a transmission shaft, partition plates connected to the lead screw move forwards or backwards along with rotation of the lead screw, and due to the fact that the two partition plates of the same set of combined mold are connected to right-hand threads and left-hand threads respectively, when the lead screw rotates, the two partition plates move face to face or back to back at the same time, and mold closing or mold opening of the mold is achieved; when a direct driving mode is adopted, driving cylinders are arranged at the two sides respectively, the driving cylinder at one side is fixedly connected to the partition plate at one side of the combined mold through a driving frame and a driving rod, and the driving cylinder at the other side is fixedly connected to the partition plate at the other side of the combined mold; and when the driving cylinders at the two sides push towards middle or pull towards two sides at the same time, the partition plates at the two sides of the combined mold move face to face or back to back at the same time, and mold closing or mold opening of the mold is achieved. The mold opening and closing mechanism has the advantages of being simple in structure, convenient to operate and easy to implement.

Description

technical field [0001] The invention relates to the technical field of kiln structure, in particular to a mold opening and closing mechanism for a kiln for producing composite lightweight wall panels. Background technique [0002] When the existing kiln for producing composite lightweight wall boards is closing the mold, it is necessary to push the first partition on one side to the last partition on the other side layer by layer (the partition cannot be fixed). When opening the mold, the first partition on one side needs to be pulled back to its original position layer by layer (mold opening). This method of opening and closing the mold has the following disadvantages: [0003] 1. In the process of mold opening and closing, the stroke of the first partition is the longest. With the increase of partitions (the body of the mold car is lengthened), the stroke required for mold opening and closing will be longer, which is not conducive to saving mold opening and closing time. ...

Problems solved by technology

[0004] 2. Before closing the mold, it is necessary to load the composite ceramic plate, so during the long-stroke mold opening and closing process, the ceramic plate will be displaced, offset, and the displacement at both ends is not synchronized;

[0005] 3. When the position of the ceramic plate deviates, it needs to be corrected in time, otherwise there will be poor sealing and grout leakage during grouting, but in this mode of opening and closing the mold, it is necessary to reopen the partition that has been closed before After the correction is completed, the mold will be closed again. Therefore, the production efficiency is low and the time cost is heavy.
