When the guide sleeve 4 slides downward, it simultaneously drives the push rod 7 to move downward through the opening inside the support plate 9, and when the push rod 7 moves downward, it drives the teeth 8 to rotate the gear 10, until the upper mold 5 and the lower mold 2 are molded together, and then the limit mechanism on the back side of the support plate 9 is used to lock the gear 10. The position after rotation is locked to limit the push rod 7, thereby realizing the function of limiting the upper mold 5 and the lower mold 2 when the mold is closed, preventing the upper mold 5 and the lower mold 2 from easily being offset in relative position and unable to align correctly due to other factors such as mechanical vibration when the mold is closed, which is beneficial to ensuring the quality of the product after molding. A vertical shaft 11 is provided on the inner side of the push rod 7 through a recess, and a fixed sleeve 12 is welded and fixed on the inner wall of the inner side of the opening of the support plate 9, and the sliding sleeve is arranged on the outside of the vertical shaft 11. The fixed sleeve 12 is located on one side of the inner end of the support plate 9. When the push rod 7 of this structure is pushed downward, it will drive the vertical shaft 11 to slide along the inside of the fixed sleeve 12 to improve the stability when pushing up and down. A rotating shaft 14 is provided at the center of the gear 10, and the rotating shaft 14 passes through the support plate 9 through a bearing.

[0019] Working principle: When using the polymer material push rod anti-misalignment device, first start the cylinder on the top mold frame 6. When the cylinder on the top mold frame 6 is driven, it will push the upper mold 5 downward. During the downward advancement of the upper mold 5, the guide sleeve 4 will be driven to slide along the outside of the guide column 3. When the guide sleeve 4 slides downward, it will simultaneously drive the push rod 7 to vertically pass through the opening inside the support plate 9. At this time, the push rod 7 will drive the vertical shaft 11 to slide along the inside of the fixed sleeve 12, and the push rod 7 will also drive the teeth 8 to produce linkage with the gear 10. After the linkage, the gear 10 will rotate with the cooperation of the rotating shaft 14, so that the upper mold 5 can be stably pushed downward and the push rod 7 and the gear 10 ... The lower mold 2 is closed until the bottom end of the push rod 7 extends into the interior of the connecting seat 13, and then the pin fixing piece is inserted into the through holes on the connecting seat 13 and the bottom end of the push rod 7 to limit and fix the push rod 7. At the same time, the stud 92 is rotated. When the stud 92 rotates inside the solid block 91, it will push the push block 93 to move horizontally until the push block 93 drives the inner wall of the locking block 94 to be embedded in the locking mouth of the outer wall of the outer end of the rotating shaft 14.
