Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-5As shown, this utility model provides a guide post for molds, mainly used for guiding the combination of the moving mold and the fixed mold. Through the optimization of the internal structure, the effect of rapid assembly is achieved. Its structure mainly includes a guide rod 1, a steel ball roller sleeve 2, a guide sleeve 3 and a return spring 4. When assembled with the mold, the guide rod 1 is assembled with the fixed mold 11, while the guide sleeve 3 is assembled with the moving mold 8.

[0022] During connection, the ball bearing sleeve 2 is movably fitted onto one end of the guide rod 1. The other end of the guide rod 1 has an outwardly protruding support portion 5. The return spring 4 is supported between the support portion 5 and the ball bearing sleeve 2. The guide sleeve 3 is movably fitted onto the outside of the ball bearing sleeve 2. When the guide rod 1 moves within the guide sleeve 3, the friction after contact is reduced by the action of the ball bearing sleeve 2. Multiple movable steel balls 6 are installed inside the ball bearing sleeve 2. The two ends of the steel balls 6 protrude and contact the guide rod 1 and the guide sleeve 3 respectively. The steel balls 6 allow the guide rod 1 to move smoothly within the guide sleeve 3, and finally, the return spring 4 returns it to its original position by its own elasticity.

[0023] To further secure the position of the return spring, the return spring 4 is assembled by sleeve-fitting it onto the outside of the guide rod 1. A limiting groove 12 for mounting the return spring 4 is provided at the end of the support 5 near the return spring 4 to prevent the return spring 4 from slipping off the support 5 and affecting the reset effect. When the guide rod 1 moves within the guide sleeve 3, a pressure cap 13 is installed at the top of the guide rod 1 to prevent the guide sleeve 3 from detaching. The end of the pressure cap 13 away from the guide sleeve 3 protrudes outwards, effectively blocking the guide sleeve 3.

[0024] During assembly, the guide sleeve 3 needs to be assembled with the moving mold 8. To facilitate assembly, an outwardly extending patch 7 is provided at one end of the guide sleeve 3. The patch 7 is used to adhere to the top of the moving mold 8 and has a mounting hole 9 for locking with the moving mold 8. The guide sleeve 3 is directly attached to the top of the moving mold 8 via the patch 7, and then locked by inserting screws or other accessories into the mounting hole 9, which is convenient. In addition, to enhance the fixation of the patch 7, a raised protrusion 14 is provided on the side of the patch 7 that contacts the moving mold 8. The protrusion 14 has a ring-shaped structure and is coaxially arranged with the guide rod 1. Correspondingly, the moving mold 8 is equipped with a first slot 15 that matches the protrusion 14. During assembly, the protrusion 14 on the patch 7 can be locked into the first slot 15 to reinforce the assembly and prevent movement.

[0025] The guide rod 1 needs to be assembled with the fixed mold 11. A connecting rod 10 protruding along the central axis is provided at one end of the guide rod 1 near the support part 5. The connecting rod 10 is used to insert into the fixed mold 11 to fix the guide rod 1. Specifically, a second slot 16 is provided on the fixed mold 11 to install both the guide rod 1 and the support part 5. At the same time, a third slot 17 is opened in the middle of the second slot 16. When the guide rod 1 and the support part 5 are engaged in the second slot 16, the connecting rod 10 is simultaneously screwed into the third slot 17 to lock and prevent it from falling off. At this time, the connecting rod 10 can be a screw structure.

[0026] Compared with traditional technologies, the mold guide pillar provided by this technical solution can be quickly and conveniently assembled with the mold. The guide sleeve 3 can be quickly locked after being attached to the top of the mold by the patch 8. After the guide rod 1 is inserted into the mold, it can be quickly locked by rotating and screwing in the connecting rod 10 at the bottom. The overall assembly is convenient, easy to disassemble and maintain, and the assembled guide pillar has high stability and is not easy to fall off.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
