Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1-4 As shown, this utility model provides a sliding block balancing guide device for injection molds, configured between the mold frame body 1 and the sliding block body 2. The sliding block body 2 slides on the mold frame body 1 and then aligns and assembles with the mold frame body 1. The balancing guide device includes multiple sets of mutually cooperating guide posts 11 and guide sleeves 21, mutually cooperating positioning grooves 12 and positioning protrusions 22, a return spring 13, a limiting block 14, and a pressure strip 15. The guide posts 11 are configured on the receiving surface of the mold frame body 1 for receiving and assembling the sliding block body 2, the guide sleeves 21 are configured on the sliding block body 2, and the positioning grooves 12 are open. A positioning protrusion 22 is disposed on the receiving surface of the mold frame body 1 and on the slider body 2. A return spring 13 is disposed on the receiving surface of the mold frame body 1 and protrudes from the receiving surface of the mold frame body 1 to apply elastic force to the assembled slider body 2. A limiting block 14 is disposed on the support surface of the mold frame body 1 for supporting and allowing the slider body to slide. After the limiting block 14 extends out of the support surface of the mold frame body 1, it blocks the slider body 2 in the direction away from the receiving surface of the mold frame body 1. A pressure strip 15 is detachably assembled on the mold frame body 1 and pressed against the top of the slider body 2.

[0024] In one specific embodiment of this utility model, the guide post 11 protrudes from the receiving surface of the mold frame body 1, and a bolt 111 is provided on the protruding end of the guide post 11. The guide post 11 is fixed to the mold frame body 1 by the bolt 111.

[0025] In one specific embodiment of this utility model, the guide sleeve 21 is assembled on the slider body 2 through the mounting hole on the slider body 2. A mounting groove is formed in the mounting hole, and a retaining spring 211 is disposed in the mounting groove. The retaining spring 211 fixes the guide sleeve 21 in the mounting hole.

[0026] Furthermore, the guide sleeve 21 is a copper guide sleeve 21 equipped with graphite, which does not require lubrication and will slide more and more smoothly during the sliding process, avoiding jamming of the slider body 2 during the production process, ensuring production continuity, and thus improving the efficiency of trial molding / injection molding production.

[0027] In one specific embodiment of this utility model, there are two pressure strips 15, which are screwed onto the mold frame body 1 and pressed onto the top of both ends of the slider body 2 respectively.

[0028] In one specific embodiment of this utility model, the end plates at both ends of the slider body 2 are wear-resistant plates 23 with oil grooves.

[0029] In one specific embodiment of this utility model, the slider body 2 is provided with a tube groove 24 at the point where the reset spring 13 acts.

[0030] In one specific embodiment of this utility model, multiple sets of guide pillars 11 and guide sleeves 21 are evenly arranged at the joint of the mold frame body 1 and the slider body 2.

[0031] Furthermore, four sets of guide pillars 11 and guide sleeves 21 are configured and evenly distributed on both sides of the mold frame body 1. This ensures that the slider body 2 is subjected to uniform force during the sliding process of the mold slider, avoiding distortion and jamming, thereby preventing the slider body 2 from getting stuck during the production process and playing a role in stabilizing and balancing the guide.

[0032] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
