Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold for an anti-deformation SUV car roof. Background Technology

[0002] As the core tool for manufacturing car roofs, the precision of the car roof mold is crucial to ensuring that the geometry, dimensional accuracy, and surface quality of the roof meet design specifications. Through precise mold design, the roof can be precisely connected with other parts of the vehicle body, thereby improving the overall appearance quality and airtightness of the vehicle. In addition, the application of molds significantly improves production efficiency, enables the large-scale production of car roofs, and effectively reduces manufacturing costs.

[0003] A Chinese patent document CN202122792279.X discloses a stamping die for an automobile roof, comprising an upper die base and a lower die base. A lower die is fixed to the upper surface of the lower die base, and a roof cutter is fixed to the center of the lower surface of the upper die base. The upper die is connected to the upper die base via a sliding rod, one end of which is fixed to the upper die base, and the other end has a limiting block that slides up and down within a limiting cavity inside the upper die. The upper die has a cutting through hole for the roof cutter to pass through, and the lower die also has a clearance groove to avoid the roof cutter. The upper and lower dies together form a mold cavity. Switching mechanisms are provided on both sides of the lower surface of the upper die base. Each switching mechanism includes a rotary motor located inside the upper die base and a switching block fixedly connected to the rotary motor. The upper surface of the switching block abuts against the upper die base. Switching slots are provided on both sides of the upper die corresponding to the positions of the switching blocks for insertion into the switching blocks. This automobile roof stamping die allows for a clear view of the current sunroof / sunroof switching state, avoiding the possibility of misoperation.

[0004] However, the above-mentioned patent has certain defects in use. Since the outer periphery of the pressure ring is equipped with a guide cylinder and a guide rod for positioning, the external nature of the guide cylinder makes it easy for the upper and lower molds to deviate when subjected to high-intensity working loads, thereby reducing the accuracy of the mold and negatively affecting the molding quality of the top cover.

[0005] To address these issues, a deformation-resistant SUV roof mold is proposed. Utility Model Content

[0006] In order to overcome the problem that the upper and lower molds in the prior art are prone to deformation under high-intensity working conditions, this utility model provides a deformation-resistant SUV car roof mold.

[0007] This utility model is achieved using the following technical solution:

[0008] Deformation-resistant SUV roof mold, including

[0009] The upper mold and the lower mold are provided with positioning holes around the upper surface of the lower mold. A positioning post is fixedly connected in the positioning hole. Multiple return springs are provided around the positioning post in the positioning hole. The other end of the multiple return springs is connected to a buffer plate.

[0010] The upper mold is provided with a movable sleeve that matches and is installed around the positioning post. The bottom of the movable sleeve is provided with a buffer block, and the movable sleeve is movably connected to the periphery of the positioning post. The upper mold is set above the lower mold through the cooperation of the movable sleeve and the positioning post.

[0011] The upper mold has an embossed pattern at the bottom center, and the lower mold has a corresponding placement area at the top center.

[0012] As a preferred embodiment of this utility model, an operating area is provided on one side of the lower mold, and a cavity is provided inside the lower mold near the operating area. A boring hole is provided at the top of the cavity through the placement area, and a limiting groove is provided on the side of the cavity near the operating area through the operating area.

[0013] As a preferred embodiment of this utility model, a movable rod is provided in the cavity, and rod sleeves are movably connected to both ends of the movable rod. The rod sleeves are disposed on the side wall of the cavity. A rocker arm is provided on the peripheral wall of the movable rod. An operating rod is provided at one end of the rocker arm. The operating rod is located in a limiting groove. A rocker head is provided at the end of the rocker arm away from the operating rod.

[0014] As a preferred embodiment of this utility model, a protective pad is provided at the bottom of the cavity, and the protective pad is located at the bottom of the upturned end.

[0015] As a preferred embodiment of this utility model, an upper connection is fixedly provided on the top of the upper mold.

[0016] As a preferred embodiment of this utility model, a limit stake is provided at the top of the positioning column.

[0017] As a preferred embodiment of this utility model, the boring hole is located on one side of the ground in the placement area, and the size of the limiting groove is matched with the upturned head.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. By setting positioning pins in the positioning holes at the four corners of the upper surface of the lower mold, and providing movable sleeves around the upper mold, the movable sleeves are movably connected to the periphery of the positioning pins, which effectively prevents mold displacement and mold deformation during high-intensity work.

[0020] 2. A limiting post is set at the top of the limiting post to limit the range of motion of the movable sleeve. Multiple return springs are installed in the positioning hole, and the other end of the springs is connected to a buffer plate. A buffer block is installed at the bottom of the movable sleeve. When the upper mold moves horizontally downward and approaches the lower mold, the movable sleeve moves downward accordingly. When the embossing is fully engaged with the placement area, the return spring bears the compressive force, which plays a buffering role between the upper mold and the lower mold to prevent direct impact.

[0021] 3. A movable rod is provided inside the cavity, with the rod sleeve connected to the two side walls of the cavity. A rocker arm is also provided on the movable rod. The operating rod is located in the limiting groove, and the rocker arm is precisely matched with the limiting groove. After the workpiece is placed in the placement area, there may be a situation where fine adjustment and demolding are inconvenient. By controlling the rocker arm with the operating rod, the rocker arm can be precisely pressed against the workpiece. The workpiece will be slightly lifted under the action of the rocker arm, making it easier to remove the demolding. Attached Figure Description

[0045] Specifically, the boring hole 51 is located on one side of the ground in the placement area 5, and the size of the boring hole 51 matches the size of the upturned head 65.

[0046] In this embodiment, the boring hole 51 is located on one side of the bottom surface of the placement area 5. The size of the boring hole 51 matches the shape of the upturned head 65 to ensure that the upturned head 65 moves smoothly within the boring hole 51.

[0047] The principle of this utility model is as follows: the workpiece is placed in the placement area 5, and the upper connection 3 controls the upper mold 1 to descend. When the upper mold 1 descends, the movable sleeve 11 moves down to the positioning hole 21 under the guidance of the positioning pin 22. When the embossing 4 is fully engaged with the placement area 5, the buffer block 12 contacts the buffer plate 23, and the return spring 24 is compressed, protecting the buffering effect between the upper mold 1 and the lower mold 2 and avoiding direct collision between the upper mold 1 and the lower mold 2. After the workpiece is cast, the upper mold 1 rises. When it is necessary to remove the workpiece, the rocker arm 63 is controlled by the operating rod 64, so that the rocker head 65 accurately holds the workpiece. The workpiece will be slightly lifted under the action of the rocker head 65, making it easy to remove the mold.
