Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a universal tire mold for reinforcing ribs. Background Technology

[0002] In the production of small-batch modified parts in industries such as automobiles, the processing of reinforcing ribs often faces a contradiction between "low development costs" and "high-quality requirements." Currently, small-batch reinforcing rib production relies heavily on manual modification, lacking both dedicated mass production tooling and standardized forming structures. Lack of precise positioning structure: During manual operation, there are no matching positioning components, and the placement of the plates lacks a unified benchmark, which leads to easy deviation of the reinforcing rib shape and poor consistency; Unstable forming structure: Manual hammering requires heating the sheet metal first, which not only weakens the strength of the parts, but also makes it impossible to guarantee the dimensional accuracy of the reinforcing ribs, and the appearance is prone to unevenness; The aforementioned problems make it difficult for manually modified reinforcing ribs to meet the quality requirements of mass-produced parts, and the production efficiency is low, making it impossible to adapt to the reinforcing rib modification needs of multiple vehicle models and multiple parts. Utility Model Content

[0003] The purpose of this invention is to provide a universal mold for reinforcing ribs to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a universal mold for reinforcing ribs, comprising a lower mold unit and an upper mold unit. The lower mold unit includes an integrally formed lower mold base and a positioning block. The positioning block has a triangular cross-section. The upper mold unit includes an upper mold base. The bottom of the upper mold base has a positioning groove adapted to the positioning block. The top of the positioning block has a forming groove. A forming block adapted to the forming groove is fixedly connected to the inner wall of the positioning groove. The processing plate is placed between the positioning block and the upper mold base. The processing plate is positioned using the positioning groove. At this time, the upper mold base is pushed by an external hydraulic device, causing the forming block to compress the processing plate and deform it into the forming groove, thereby forming a raised reinforcing rib on the outside of the plate.

[0005] Preferably, the positioning block has an R-angle segment at the top corner, and the inner wall of the positioning groove is adapted to the R-angle segment.

[0006] Preferably, a contact element is installed on the top of the upper mold unit, and external hydraulic equipment applies pressure to the upper mold unit through the contact element.

[0007] Preferably, the contact element includes an integrally formed top plate and a side plate, which are respectively attached to the top and outer side of the upper mold base.

[0008] Preferably, a worktable is fixedly installed at the bottom of the lower mold unit.

[0009] The technical effects and advantages of this utility model are as follows: By matching the positioning block of the lower mold unit with the positioning groove of the upper mold unit, the processed sheet material can be quickly positioned, avoiding the reference deviation of manual operation and ensuring the uniformity of the shape of the reinforcing ribs in different batches. The forming groove and the forming block are precisely matched, and the sheet material can be directly deformed in the groove under hydraulic drive without heating processing, effectively avoiding the weakening of the part strength. At the same time, the R-corner section at the top of the positioning block matches the inner wall of the positioning groove, which can prevent the edge of the sheet material from cracking during extrusion and improve the appearance quality of the reinforcing ribs.

[0012] 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.

[0013] This utility model provides, for example Figures 1-4 The universal mold for reinforcing ribs shown includes a lower mold unit 1 and an upper mold unit 2. The lower mold unit 1 includes an integrally formed lower mold base 11 and a positioning block 12. The positioning block 12 has a triangular cross-section. The upper mold unit 2 includes an upper mold base 21. The bottom of the upper mold base 21 has a positioning groove 22 that matches the positioning block 12. The top of the positioning block 12 has a forming groove 13. A forming block 23 that matches the forming groove 13 is fixedly connected to the inner wall of the positioning groove 22. The processing plate is placed between the positioning block 12 and the upper mold base 21. The processing plate is positioned by the positioning groove 22. At this time, the upper mold base 21 is pushed by an external hydraulic device, so that the forming block 23 squeezes the processing plate into the forming groove 13 and deforms it, thereby forming a raised reinforcing rib on the outside of the plate.

[0014] Furthermore, an R-angle segment 14 is provided at the top corner of the positioning block 12, and the inner wall of the positioning groove 22 is adapted to the R-angle segment 14.

[0015] By adapting the positioning block 12 of the lower mold unit 1 to the positioning groove 22 of the upper mold unit 2, the processed sheet material can be quickly positioned, avoiding the reference deviation of manual operation and ensuring the uniformity of the shape of the reinforcing ribs in different batches. The forming groove 13 and the forming block 23 are precisely matched, and the sheet material can be directly deformed in the groove under hydraulic drive without heating processing, effectively avoiding the weakening of the part strength. At the same time, the R-corner section 14 at the top of the positioning block 12 is adapted to the inner wall of the positioning groove 22, which can prevent the edge of the sheet material from cracking during extrusion and improve the appearance quality of the reinforcing ribs.

[0016] Furthermore, a contact element 3 is installed on the top of the upper mold unit 2, and external hydraulic equipment applies pressure to the upper mold unit 2 through the contact element 3.

[0017] Furthermore, the contact element 3 includes an integrally formed top plate 31 and side plate 32, which are respectively attached to the top and outer side of the upper mold base 21.

[0018] The top plate 31 of the contact element 3 is attached to the top of the upper mold base 21 and the side plate 32 is attached to the outside of the upper mold base 21. This can evenly transmit the pressure of the external hydraulic equipment to the upper mold unit 2, avoid the molding error caused by the offset of the upper mold base 21, and further ensure the dimensional accuracy of the reinforcing rib. Furthermore, a worktable 4 is fixedly installed at the bottom of the lower mold unit 1.

[0019] First, fix the lower mold unit 1 on the workbench 4 to ensure the stability of the lower mold. Then, install the contact piece 3 on the top of the upper mold unit 2 so that the top plate 31 of the contact piece 3 is completely attached to the top of the upper mold base 21 and the side plate 32 is attached to the outside of the upper mold base 21 to complete the overall assembly of the mold. The sheet material to be processed is placed stably between the positioning block 12 of the lower mold unit 1 and the upper mold unit 2, ensuring that the sheet material covers the forming groove 13 area on the top of the positioning block 12, in preparation for subsequent forming. The upper mold unit 2 is driven to move slowly downward, so that the positioning groove 22 at the bottom of the upper mold base 21 is aligned with and fitted with the positioning block 12. Through the fit between the two, the precise positioning of the processed plate is achieved, and the positional deviation is eliminated. Start the external hydraulic equipment so that its output end contacts the top plate 31 of the contact member 3. Apply uniform downward pressure to the upper mold unit 2 through the contact member 3. The upper mold unit 2 continues to move downward, and the forming block 23 on the inner wall of the upper mold base 21 gradually squeezes the plate, forcing the plate to deform into the forming groove 13 of the positioning block 12 until the forming block 23 is embedded in the forming groove 13, and a raised reinforcing rib is formed on the outer side of the plate. The hydraulic equipment stops applying pressure and retracts upward, causing the upper mold unit 2 to reset; after the upper mold base 21 is completely removed from the plate, the processed plate with reinforcing ribs is taken out, completing a single molding operation, and can proceed to the next batch of processing.

[0020] 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.
