Description

Technical Field

[0001] This utility model relates to the field of lifting mechanisms, and in particular to a lifting mechanism for an automotive sealing strip corner mold. Background Technology

[0002] The corner mold for automotive sealing strips is a key mold used in the production of automotive sealing strips, especially at the corners of the sealing strips. The design and manufacturing quality of this mold directly affect the sealing performance, appearance quality, and production efficiency of the sealing strips.

[0003] Due to the shape of automotive sealing strips, the manufacturing process of automotive sealing strip molds requires not only the cooperation of upper and lower molds, but also the setting of a corner mold core on the lower mold. After the upper and lower molds are separated, the corner mold core moves upward relative to the lower mold, allowing the sealing strip to be removed from the outside of the corner mold core.

[0004] When the corner mold core moves up and down, it is usually driven by a cylinder. This requires a drive cylinder to be installed at the bottom of the lower mold of the sealing strip. This will cause a protruding part to form at the bottom of the sealing strip mold, which will affect the installation and use of the sealing strip mold and thus have certain defects. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting mechanism for automotive sealing strip corner molds to solve the problems mentioned in the background art.

[0030] 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.

[0031] This utility model provides, for example Figure 1-5 The illustrated automotive sealing strip corner mold lifting mechanism includes a mounting plate 1, a lower mold 2 fixedly mounted on the top of the mounting plate 1, and a corner mold core 3 provided on the top of the lower mold 2. Figure 1 As shown, when the lower mold 2, corner mold core 3, and upper mold are used together, the corner sealing strip of an automobile can be injection molded. The corner sealing strip is wrapped around both sides of the corner mold core 3. This is existing technology and will not be described in detail here. A lifting assembly is provided between the mounting plate 1 and the lower mold 2. The lifting assembly is used to drive the corner mold core 3 to move up and down. The lifting assembly includes a drive column 41 and a drive component 43. The top of the drive column 41 is fixedly connected to the corner mold core 3. The drive component 43 is used to drive the drive column 41 to move up and down. When the drive component 43 pushes the corner mold core 3 to move up through the drive column 41, the sealing strip on the outside of the corner mold core 3 can be directly removed. After the drive column 41 drives the corner mold core 3 to descend and reset, the bottom of the drive column 41 is higher than the bottom of the mounting plate 1, so that the bottom of the mounting plate 1 will not form a protruding part, which facilitates the installation and use of the mounting plate 1 and the lower mold 2.

[0032] In particular, the drive assembly 43 includes a drive cylinder 431 and a drive plate 432. The drive cylinder 431 is disposed on one side of the mounting plate 1, and the drive plate 432 is horizontally slidably disposed between the mounting plate 1 and the lower mold 2. The two drive plates 432 slide horizontally between the mounting plate 1 and the lower mold 2 without causing a protrusion at the bottom or side of the mounting plate 1 and the lower mold 2, thereby avoiding increasing the external volume between the mounting plate 1 and the lower mold 2. The sliding of the drive plate 432 is used to drive the drive column 41 to move up and down. The drive assembly 43 also includes a fixing frame 437 and a fixing member 438. The drive cylinder 431 is mounted on the fixing frame 437, and the output end of the drive cylinder 431 is connected to the fixing member 438. The side of the fixing member 438 is connected to the drive plate 432, so that the drive cylinder 431 can drive the two drive plates 432 to slide between the mounting plate 1 and the lower mold 2 through the fixing member 438.

[0033] In particular, the drive assembly 43 also includes a guide shaft 433, a thickened portion 434, and a guide hole 435. The middle part of the outer wall of the guide shaft 433 is fixedly connected to the drive column 41. The thickened portion 434 is disposed at the bottom of the drive plate 432. The guide hole 435 is opened on one side of the drive plate 432. The end of the outer wall of the guide shaft 433 is slidably sleeved with the guide hole 435. Figure 5 As shown, the guide hole 435 on the drive plate 432 has an inclined portion and two horizontal portions. When the drive plate 432 slides relative to the mounting plate 1 and the lower mold 2, the guide shaft 433 slides in the inclined portion of the guide hole 435. The guide shaft 433 can drive the drive column 41 to slide up and down. When the guide shaft 433 is located at the horizontal end in the guide hole 435, the drive column 41 drives the corner mold core 3 to be at the top and bottom.

[0034] Furthermore, the top of the mounting plate 1 is symmetrically provided with connecting holes 436, and the thickened part 434 is slidably sleeved inside the connecting hole 436. The sliding of the thickened part 434 in the connecting hole 436 can improve the stability of the drive plate 432 sliding between the mounting plate 1 and the lower mold 2. The bottom of the lower mold 2 is provided with a connecting groove, and the outer wall of the drive plate 432 is slidably sleeved with the inner cavity of the connecting groove. The bottom of the lower mold 2 and the top of the mounting plate 1 are both provided with mounting holes 42, and the outer wall of the drive column 41 is slidably sleeved with the inner cavity of the mounting hole 42. The inner cavity of the mounting hole 42 is interconnected with the inner cavity of the connecting groove and the inner cavity of the connecting hole 436. The slidable sleeve of the drive column 41 with the mounting hole 42 can ensure the stability of the drive column 41 driving the corner mold core 3 to move up and down.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
