Description

Technical Field

[0001] The utility model relates to the technical field of mold top plate components, in particular to a top plate sliding structure and a top plate component. Background Art

[0002] Existing top plate sliding structure such as Figure 1 As shown, a mounting hole group is provided on the top plate 1, and sliding grooves 12' extending along the Y-axis direction are respectively provided on both sides of the mounting hole group on the top plate 1, and the left and right sides of the sliding groove 12' are respectively connected with a first sliding bar 21' and a second sliding bar 22' for sliding along the Y-axis direction, and a mounting recess 4' adapted to the T-shaped pressure bar 3' is formed between the first sliding bar 21' and the second sliding bar 22', and the T-shaped pressure bar 3' is installed in the mounting recess 4' and fixedly connected to the top plate 1', and the T-shaped pressure bar 3' limits the first sliding bar 21' and the second sliding bar 22' in the sliding groove 12' in the X-axis direction and the Z-axis direction.

[0003] The above top plate sliding structure has the following disadvantages:

[0004] 1. The installation and connection of the T-shaped pressure strip 3' is only positioned by the movable first sliding bar 21' and the second sliding bar 22', which may easily cause a certain offset of the T-shaped pressure strip 3' relative to the Y-axis direction during the installation and connection.

[0005] 2. Since the T-shaped pressure strip 3' needs to position the first sliding bar 21' and the second sliding bar 22' in many aspects, after long-term use, the connection between the T-shaped pressure strip 3' and the top plate 1' is prone to loosening, and the loosened T-shaped pressure strip 3' will also produce a certain offset relative to the Y-axis direction.

[0006] 3. The material of the T-shaped pressure strip 3' is copper. After the top plate sliding structure has been used for a period of time, the sliding contact surfaces between the T-shaped pressure strip 3' and the first sliding strip 21' and the second sliding strip 22' will be worn to a certain extent.

[0007] The T-shaped pressure strip 3' after deviation, looseness and wear cannot limit the first sliding bar 21' and the second sliding bar 22' well, especially in the X-axis direction. Once the limiting effect in the X-axis direction fails, the first sliding bar 21' and the second sliding bar 22' will slide along the Y-axis direction and produce a certain deviation, so that the mold cannot move completely along the mold opening and closing direction, thereby affecting the mold opening and closing process, and further affecting the quality of the preform product, and also accelerating the wear of the first sliding bar 21' and the second sliding bar 22', affecting their service life.
