Description

Technical Field

[0001] This utility model relates to the field of automotive lighting manufacturing technology, specifically to a tooling fixture that facilitates the removal of the guide sleeve from the front. Background Technology

[0002] Mold cooling water channels and mold guide sleeves are indispensable components in existing injection molds. Currently, in order to improve mold production efficiency, more accurately control temperature, and optimize the molding of injection molded products, the water channels inside the mold are arranged very densely, many of which pass through the inside of the guide sleeves. For on-site operators, blocking water during the process requires removing the guide sleeves. So how to remove the guide sleeves in the most time-saving and labor-saving way is a headache for on-site personnel. Summary of the Invention

[0003] In order to solve the technical problem that the guide sleeve is not easy to remove from the mold without disassembling the mold in the prior art, this application proposes a tooling device that facilitates the removal of the guide sleeve from the front, thus solving the above-mentioned technical problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides a tooling fixture for easy frontal removal of a guide sleeve, comprising: a rod body, which is vertically inserted into one end of the guide sleeve and exits through the other end of the guide sleeve; the force-bearing end of the rod body not inserted into the guide sleeve forms a circumferentially expanding hanging platform; the adjusting end of the rod body penetrating the guide sleeve is connected to a horizontally configured connecting sleeve; a force-bearing bolt, which is fitted at both ends of the connecting sleeve to adjust the maximum diameter of the adjusting end of the rod body; after the connecting sleeve exits the guide sleeve, the force-bearing bolt is adjusted so that the maximum diameter of the adjusting end is greater than the inner diameter of the guide sleeve so that the rod body acts on the guide sleeve; and a gripping slide sleeve, which is slidably disposed on the rod body; when removing the guide sleeve, the gripping slide sleeve frequently impacts the hanging platform upwards to dislodge the guide sleeve.

[0006] Furthermore, the rod is configured as a split type, with the two segments of the rod being detachably connected at the middle section of the rod.

[0007] Furthermore, the two separate sections of the rod are connected together by screws.

[0008] Furthermore, a horizontally arranged threaded channel is formed inside the connecting sleeve, and the two ends of the threaded channel are screwed with the force-bearing bolts. During the removal of the guide sleeve, the nut of the force-bearing bolt abuts against the wall thickness at the end of the guide sleeve.

[0009] Furthermore, the outer wall surface of the grip sleeve is provided with a pattern that facilitates gripping.

[0010] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0011] This utility model discloses a tooling device for removing the guide sleeve from the front. First, the force-bearing bolt is rotated clockwise to screw it into the connecting sleeve. The maximum diameter of the adjusting end of the rod is smaller than the inner diameter of the guide sleeve. The adjusting end of the rod is inserted into the guide sleeve and passes through the other end of the guide sleeve. Then, the force-bearing bolt is rotated counterclockwise to make the maximum diameter of the adjusting end of the rod larger than the inner diameter of the guide sleeve. When the rod is lifted vertically upward again, the force-bearing bolt will abut against the wall thickness at the end of the guide sleeve. The force of lifting the rod vertically upward will act on the guide sleeve. Then, the sliding sleeve is repeatedly pulled upward by holding the sliding sleeve. By repeatedly hitting the hanging platform of the rod with the sliding sleeve, the guide sleeve is pulled out from the mold frame. Thus, the guide sleeve is removed from the mold from the front without demolding, which facilitates on-site operation, reduces processing costs, and reduces the overall demolding time.

[0018] 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. 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.

[0019] The guide sleeve is stuck in the mold. In the existing technology, the mold needs to be removed first (the mold is very heavy and requires mechanical tools such as cranes to lift it). Then, a push rod is used to enter the mold frame through the hole at the bottom of the mold frame and push the guide sleeve from bottom to top to remove the guide sleeve. The whole process is time-consuming and laborious.

[0020] like Figure 1-5 As shown, the tooling for easy frontal removal of the guide sleeve of this utility model includes a rod 1, a load-bearing bolt 2, and a gripping sleeve 3. The rod 1 is vertically inserted into one end of the guide sleeve 4 and exits through the other end of the guide sleeve 4. The load-bearing end of the rod 1 that is not inserted into the guide sleeve 4 forms a circumferentially expanding hanging platform 11. The adjusting end of the rod 1 that passes through the guide sleeve 4 is connected to a horizontally arranged connecting sleeve 12. The load-bearing bolt 2 is assembled at both ends of the connecting sleeve 12 to adjust the maximum diameter of the adjusting end of the rod 1. After the connecting sleeve 12 exits the guide sleeve 4, the load-bearing bolt 2 is adjusted so that the maximum diameter of the adjusting end is greater than the inner diameter of the guide sleeve 4 so that the rod 1 acts on the guide sleeve 4. The gripping sleeve 3 is slidably arranged on the rod 1. When removing the guide sleeve 4, the gripping sleeve 3 frequently strikes the hanging platform 11 upwards to make the guide sleeve 4 disengage from the mold 5.

[0021] In a preferred embodiment of this invention, the rod 1 is configured as a split type, with the two sections of the rod 1 being detachably connected at the middle section. This allows for the adaptation to different specifications of guide sleeves 4 by replacing different sections of the rod 1 with mounting brackets 11.

[0022] Furthermore, the two sections of the rod 1 are connected together by screwing. Specifically, a threaded hole can be provided on one section of the rod 1, and a threaded part that mates with the threaded hole can be provided on the other section.

[0023] In a preferred embodiment of this utility model, a horizontally arranged threaded channel is formed inside the connecting sleeve 12, and the two ends of the threaded channel are screwed with force-bearing bolts 2. During the process of removing the guide sleeve 4, the nuts of the force-bearing bolts 2 abut against the wall thickness at the end of the guide sleeve 4.

[0024] In a preferred embodiment of this utility model, the outer wall surface of the gripping slide 3 is provided with a pattern that facilitates gripping.

[0025] 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.
