DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0024] The outer side of the connecting rod 4 is fixedly connected with a fixing mechanism, the fixing mechanism includes a clamping plate 1001, and a clamping sleeve 1002 is embedded in the upper mold 2, and the clamping sleeve 1002 is clearance-matched with the clamping groove.

[0025] The upper mold 2 is provided with four opening grooves 1003 inside. The four opening grooves 1003 are arranged opposite to the mold frame 3 , and the opening grooves 1003 and the mold frame 3 are clearance-matched.

[0026] The working principle of this embodiment is as follows: when the upper mold 2 is moved close to the lower mold 1, the upper mold 2 is sleeved on the mold frame 3 of the lower mold 1 through the internal opening groove 1003. As the upper mold 2 moves downward, the positioning plate 8 will be pushed toward the side close to the sliding plate 6 along the slope of the positioning plate 8, so that the positioning plate 8 leaves the opening groove 1003. Then, when the upper mold 2 contacts the lower mold 1, the positioning plate 8 enters the positioning groove 9 on the outer side of the mold frame 3 under the elastic force of the spring 7. At this time, the upper mold 2 can be positioned by the cooperation of the positioning plate 8 and the positioning groove 9 to prevent the upper mold 2 and the lower mold 1 from shaking and shifting after they are closed. By setting the positioning plate 8 and the positioning groove 9, the upper mold 2 and the lower mold 1 can be automatically fixed after they are closed, thereby improving the convenience of using the mold.

[0027] After the injection molding is completed, when the upper mold 2 needs to be removed, the user can move the handle 5 to the side away from the upper mold 2, and the handle 5 drives the connecting rod 4 to move to the side away from the upper mold 2. When the connecting rod 4 drives the sliding plate 6 to contact the inner wall of the upper mold 2, the positioning plate 8 completely leaves the opening groove 1003. At this time, the connecting rod 4 is rotated to make the clamping plate 1001 on the outside of the connecting rod 4 enter the clamping sleeve 1002, so as to fix the position of the connecting rod 4. Then the upper mold 2 can be moved upward to separate the upper mold 2 and the lower mold 1.
