[0027] Refer to the drawings Figure 1 , Figure 2 and Figure 3When the mold is used, the outer side wall of the guide rod 3 and the inner mounting sliding sleeve of the top mold 4 are prone to wear after long-term use due to the frequent and repeated sliding of the top mold 4 along the guide rod 3, thereby causing the butt joint of the bottom mold plate 2 and the top mold 4 to deviate. Therefore, a plurality of installation grooves 502 are provided at equal intervals on the outer side of the guide rod 3, and an oil absorption sponge sleeve 504 with oil absorption characteristics is sleeved at the installation grooves 502. After the lubricant is injected into the guide rod 3, the oil absorption sponge sleeve 504 gradually absorbs the lubricant through the oil absorption sponge 505. When the top mold 4 slides up and down along the guide rod 3, the inner sliding sleeve of the top mold 4 gradually comes into contact with the plurality of oil absorption sponge sleeves 504 and is contaminated with a certain amount of lubricant, thereby lubricating the inner sliding sleeve of the top mold 4 and the guide rod 3.

[0028] The bottom mold plate 2 is fixedly connected with a buffer structure 6 at both ends, and the buffer structure 6 includes a top frame 601, an inclined guide frame 602, a top block 603, a buffer pad 604, a sliding rod 605, a buffer spring 606, a guide frame 607, and a guide groove 608. The top frame 601 is fixedly connected to the two sides of the top mold 4. The two sides of the bottom mold plate 2 are fixedly connected with the inclined guide frame 602. The inclined guide frame 602 is slidably connected with the top block 603 inside. The top end of the top block 603 is fixedly connected with the buffer pad 604.

The upper positioning block 701 and the lower positioning block 703 are in the same vertical plane.

[0031] Referring to the drawings Figure 1 , Figure 4and Figure 6 In order to ensure the accuracy of the butt joint of the bottom mold plate 2 and the top mold 4 and avoid deviation of the butt joint of the bottom mold plate 2 and the top mold 4, the ball 702 is installed on the inside of both sides of the bottom mold plate 2, and the lower positioning block 703 is installed on the inside of both sides of the top mold 4. When the bottom mold plate 2 and the top mold 4 are accurately closed, the upper positioning block 701 is stably inserted into the inside of the lower positioning block 703. When there is a certain deviation, the upper positioning block 701 cannot be stably inserted into the inside of the lower positioning block 703, and then the operator maintains it. In order to avoid the wear of the butt joint of the upper positioning block 701 and the lower positioning block 703, the ball 702 is rolled in the inside of both ends of the bottom of the upper positioning block 701, so as to reduce the wear of the upper positioning block 701 and the lower positioning block 703.
