Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure forming, in particular to a high-pressure forming mold for automobile exterior decoration. Background Art

[0002] Automotive exterior high-pressure molding molds are specialized tools used to produce automotive interior and exterior trim. These molds are capable of molding plastic or other composite materials under high pressure. This technology is particularly popular in the automotive industry because it can produce parts that are both beautiful and functional, such as windows, lampshades, and decorative strips.

[0003] After investigation, a Chinese patent discloses a secondary injection molding mold for automotive accessories (publication number: CN215750464U), including an upper pressing plate and a fixing hole. The surface of the upper pressing plate is provided with a fixing hole. Before injection molding, the injection hole at the top of the upper pressing plate is connected to the injection molding equipment, so that the fixing hole on the surface of the upper pressing plate is aligned with the guide column provided on the surface of the base, and then the upper pressing plate is pressed down to the top of the bottom mold, and then the number block on the surface of the marking module is fixed to the inside of the fixing groove at the front end of the marking module, and then the fixing bolt is inserted into the limiting hole at the top of the surface, and the number block at the front end of the marking module is fixed with the corresponding digital number, and the marking module is inserted into the inside of the marking groove, and then the injection molding material is passed through the injection hole. The internal mold prints the product number on the automobile mold through the marking module on the side of the bottom mold, reducing the tediousness and processing cost of secondary processing. Compared with the traditional injection molding mold, the workpiece is numbered during use, which improves product production efficiency and reduces production costs.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a high pressure forming mold for automobile exterior decoration, such as Figure 1 、 Figure 2 and Figure 4 As shown, the mold includes a base plate 1 , a lower template 4 arranged on the base plate 1 , and a fixing mechanism fixedly installed on the base plate 1 for fixing the lower template 4 .

[0027] The fixing mechanism includes a first clamping block 2 fixedly mounted on the top of the base plate 1, a second clamping block 3 slidably mounted on the top of the base plate 1 and in contact with the first clamping block 2, a fixing block 9 fixedly mounted on one side of the first clamping block 2, a connecting column 11 fixedly mounted on the fixing block 9, a second spring 10 sleeved on the connecting column 11, a slider 14 fixedly mounted on the second clamping block 3, and a connecting plate 12 fixedly mounted on the end of the connecting column 11 away from the fixing block 9.

[0028] The top of the first clamping block 2 is fixedly connected to the limiting column 7, the top of the second clamping block 3 is fixedly connected to the limiting column 7 which is the same as the top of the first clamping block 2, the side surface of the limiting column 7 is sleeved with a first spring 8, the limiting block 6 is slidably connected to the limiting column 7, one side of the limiting block 6 is fixedly connected to the upper template 5, the limiting block 6 is arranged on the top of the first spring 8, one end of one first spring 8 is fixedly connected to the top of the first clamping block 2, and one end of the other first spring 8 is fixedly connected to the top of the second clamping block 3.

[0029] The lower template 4 and the upper template 5 of the mold can be replaced as a set. In order to ensure stability during the die-casting process, the lower template 4 is clamped and fixed by the first clamping block 2 and the second clamping block 3 on the base plate 1. The first clamping block 2 is fixed on the base plate 1. Therefore, when fixing or replacing the lower template 4, it is achieved by the movement of the second clamping block 3. The upper template 5 is connected to the limit column 7 on the top of the first clamping block 2 and the second clamping block 3 by the limit block 6. Therefore, when installing the lower template 4 and the upper template 5, it is necessary to install the lower template 4 first, and then install the upper template 5. When disassembling and replacing, the opposite operation is performed. The die-casting material is placed between the lower template 4 and the upper template 5, and then pressure is applied to the upper template 5 through the die-casting machine until the lower template 4 and the upper template 5 fit together.

[0030] The arrangement of the first spring 8 can automatically bounce up the upper mold plate 5 after the die-casting machine is removed from the upper mold plate 5, thereby simplifying the manual demoulding operation.

[0031] Furthermore, in order to enable the second clamping block 3 to clamp and fix the lower template 4, as shown in FIG. Figure 1 、 Figure 2 and Figure 4 As shown, the top of the base plate 1 is fixedly connected to a rotating shaft 18 , the rotating handle 15 is rotatably connected to the rotating shaft 18 , the special-shaped block 17 is rotatably connected to the rotating shaft 18 , and the bottom of the special-shaped block 17 is fixedly connected to the top of the rotating handle 15 .

[0032] By rotating the handle 15, the handle 15 drives the special-shaped block 17 to rotate. When the special-shaped block 17 rotates, its surface will squeeze the second clamping block 3 and the connecting plate 12, forcing the second clamping block 3 to move and then fix the lower template 4. When the lower template 4 needs to be replaced, it is only necessary to rotate the handle 15 in the opposite direction to release the lower template 4 fixed by the second clamping block 3.

[0033] In order to enable the second clamping block 3 to move automatically, Figure 1 、 Figure 2 and Figure 3 As shown, the connecting column 11 passes through the slider 14 , one end of the second spring 10 is fixedly connected to one side of the fixed block 9 , and the other end of the second spring 10 is fixedly connected to one side of the slider 14 .

[0034] After the handle 15 is rotated in the opposite direction, the second clamping block 3 can be automatically separated from the first clamping block 2 by the force of the second spring 10, thereby releasing the clamped lower template 4, reducing the process of manual intervention.

[0035] It should be noted that, in order to improve the stability of the second clamping block 3 during movement, Figure 1 、 Figure 3 and Figure 5 As shown, a slide bar 13 is fixedly connected to the bottom of the second clamping block 3 , and the slide bar 13 is inserted into the interior of the bottom plate 1 . A slide groove is provided inside the bottom plate 1 for the slide bar 13 to slide.

[0036] The slide bar 13 fixed at the bottom of the second clamping block 3 can slide inside the bottom plate 1 and provide a limiting function for the second clamping block 3, thereby improving the stability of the second clamping block 3 when moving.

[0037] Furthermore, in order to improve the stability of the handle 15 during operation, Figure 2 、 Figure 4 and Figure 5 As shown, a plug-in rod 16 is movably connected to the handle 15, and a fixing groove for the plug-in rod 16 to be plugged in is provided on the bottom plate 1.

[0038] The turning handle 15 is provided to drive the special-shaped block 17 to adjust the second clamping block 3 so that it can clamp and fix the lower template 4. In order to prevent the turning handle 15 from moving after rotation, a connecting rod 16 is used to pass through the turning handle 15 and be connected to the base plate 1 to achieve the stability of the turning handle 15.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
