Description

Technical Field

[0001] This utility model relates to the field of automotive interior mold technology, specifically to an automotive interior mold insert gap adjustment device. Background Technology

[0002] An automotive interior mold insert gap adjustment device is a device used to adjust the gap between inserts in an automotive interior mold. It aims to improve the cutting effect of the mold, utilize space and improve production quality, while facilitating the long-term use and maintenance of the mold. This device is commonly used in the injection molding and compression molding processes of automotive interior parts to ensure the dimensional accuracy and appearance quality of the interior parts.

[0003] An existing automotive interior trim mold insert gap adjustment structure, such as Chinese patent application number 202222311185.0, includes an upper mold and a lower mold. An insert is mounted on the upper surface of the lower mold. The insert is divided into an inner cutting edge and an outer cutting edge. The top of the inner and outer cutting edges are respectively provided with an inner cutting edge and an outer cutting edge. The outer cutting edge is bolted to the upper surface of the inner cutting edge. Shims are provided at the gaps between the lower surface of the inner cutting edge and the upper surface of the lower mold, and between the lower surface of the outer cutting edge and the upper surface of the inner cutting edge. If the inner and outer cutting edges cannot achieve the expected cutting effect or cannot switch automotive interior trim, the height of the inner and outer cutting edges can be adjusted by adding or removing shims on the underside of the inner or outer cutting edge to meet the cutting effect of the upper and lower molds on the automotive interior trim. This improves the utilization of mold space, facilitates the control of mold product production quality, and helps with the long-term use and maintenance of the mold. However, this device still has some shortcomings.

[0004] When adjusting the gap between automotive interior trim inserts, the device still uses manual placement of shims for gap adjustment, followed by bolt locking. However, the shims are prone to shifting during placement, requiring manual adjustment, which is cumbersome and inconvenient.

[0005] Therefore, we propose an automotive interior trim insert gap adjustment device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a gap adjustment device for automotive interior molding inserts, so as to solve the problem that the existing devices mentioned in the background art still use manual placement of shims to adjust the gap of automotive interior molding inserts, and then lock them with bolts. However, when placing the shims, the position of the shims is easy to shift, requiring manual adjustment, which is cumbersome and inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gap adjustment device for automotive interior mold inserts, comprising a lower mold and an upper mold, wherein the upper mold is located above the lower mold and both sides of the upper mold are provided with embedding grooves, the outer surface of the embedding groove is provided with an insert body, and the insert body includes an inner cutting block and an outer cutting block, wherein the outer cutting block is located on the outer surface of the inner cutting block, the bottom of both sides of the upper mold is provided with sliding grooves, and a sliding rod is fixedly connected inside the sliding grooves, and a pushing block is slidably connected to the outer surface of the sliding rod, wherein one side of the pushing block is connected to a threaded rod.

[0008] The upper mold has positioning grooves on both sides of its bottom, and a positioning rod is slidably connected inside the positioning groove, with the positioning rod passing through the interior of the inner and outer cutting blocks.

[0009] Preferably, cavities are provided inside both sides of the upper mold, and a locking rod is slidably connected inside the cavity. A tension spring is connected between the locking rod and the cavity, and a locking groove is provided on one side of the positioning rod, and the locking rod is slidably connected to the locking groove.

[0010] By using the above technical solution, pulling the locking rod separates it from the slot at the positioning rod, and the locking rod and positioning rod separate from the upper mold, thus facilitating the replacement or maintenance of the insert body.

[0011] Preferably, one end of the inner blade block is provided with an inclined surface, and the end of the pushing block that is close to the inner blade block is provided with the same inclined surface.

[0012] The above technical solution uses inclined surfaces at the ends of both the inner blade block and the pushing block. This design allows the pushing block to smoothly push the inner blade block and adjust its position or state when it moves.

[0013] Preferably, a limiting groove is formed on one side of the embedding groove, and a limiting block is slidably connected inside the limiting groove, and the limiting block is fixedly connected to the inner blade block.

[0014] By adopting the above technical solution, the inner cutting block can drive the limiting block to move along the limiting groove when the inner cutting block moves, thereby preventing the inner cutting block from deviating and providing a certain degree of auxiliary support.

[0015] Preferably, the top of the lower mold is slidably connected to a top plate, and the interior of the lower mold has a placement cavity. A fixing rod is fixedly connected inside the placement cavity, and a sliding sleeve is slidably connected to the outer surface of the fixing rod.

[0016] Preferably, the sliding sleeves are symmetrically arranged about the central axis of the fixed rod, and a support spring is fixedly connected between the two sliding sleeves, and a connecting rod is hinged between the sliding sleeves and the top plate.

[0017] Using the above technical solution, the sliding sleeve is slidably connected to the fixed rod, and the support spring is sleeved on the outer surface of the fixed rod. The support spring can drive the sliding sleeve to return to its original position.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the gap adjustment device for automotive interior molding blocks;

[0019] 1. By setting up the insert body, slide groove, slide rod, push block, threaded rod, positioning groove, positioning rod, cavity, locking rod and tension spring, the locking rod is pulled outward to separate the locking rod from the locking groove at the positioning rod. Then the threaded rod is rotated to drive the push block to move horizontally. When the inclined surface at the push block is in contact with the inclined surface at the inner cutting block, the inner cutting block and the outer cutting block can be pushed to move vertically. This makes it easier to adjust the gap of the insert body, enhances the flexibility and adaptability of the mold body, and improves the utilization rate and production efficiency of the mold body.

[0020] 2. Through the set top plate, placement cavity, fixed rod, sliding sleeve, support spring and connecting rod, when the upper mold descends, the material contacts the upper mold and descends with the top plate, so that the material is stamped. When the top plate descends, it can push the connecting rod to descend and push the sliding sleeve to slide on the outer surface of the fixed rod. When the sliding sleeve moves, it can stretch the support spring. When the upper mold rises, the support spring drives the sliding sleeve to reset and pushes the top plate to rise, so that the top plate can push the material out and prevent the material from sticking to the lower mold.
