Description

Technical Field

[0001] The present application relates to the field of mold processing, and in particular to a hot forming mold with a reference platform. Background Art

[0002] The tight mold development cycle has led to a shorter mold debugging cycle and tight production tasks. When debugging the mold to produce products that meet the requirements in the early stage, it is necessary to change the molding block profile many times. Relatively complex molds require repeated modification of the profile to debug and produce products with qualified appearance and size. After the mold is mass-produced, the molding block will be severely worn after reaching a certain lifespan. The molding block needs to be processed to ensure the stability of product size and appearance. During the early debugging process and the later mold mass production, the molding blocks will be reused. When processing the molding blocks, generally multiple molding blocks are assembled together to ensure the accuracy of the profile. Sometimes, in order to shorten the processing time, a single molding block will be directly used after being processed in place.

[0003] In the related technology, such as Figure 1 As shown, the mold includes a molding block, a positioning pin, a side stopper and a product. The side stopper and the positioning pin are used to position the blank so that the blank can be accurately put into the mold surface position. The upper and lower molds of the mold are pressed down by a press machine to produce qualified products.

[0004] During the debugging process of the mold, it is often not very smooth to debug the product with the appearance and size that meet the requirements. We will solve the problems that arise during the debugging process in a targeted manner. For example, when the product size is out of tolerance and unstable, the mold surface will be optimized according to the actual product size, and the mold block surface will be reprocessed. At the same time, for those molds after mass production, when the mold block reaches a certain life, the surface of the mold block will be severely worn, and the mold block surface needs to be re-carved to ensure the stability of the produced product.

[0005] There are currently two processing methods for processing forming blocks: ① single-piece processing; ② assembly processing of multiple forming blocks. The disadvantages of the current processing methods are:

[0006] 1. When the forming block needs to have its surface engraved, the latest surface data can only be obtained through methods such as blue light scanning, increasing costs. 2. When the forming block wears out and a new one is made, in order to ensure the surface of the newly made forming block, the old forming block needs to be removed to obtain the surface data and then process the new forming block. When production tasks are tight, it affects production efficiency. 3. When directly making according to 3D data, the surfaces of the old and new forming blocks may be different, resulting in the newly made forming block being unusable. 4. It is impossible to quickly confirm whether the physical object and the 3D data surface are consistent. 5. During the production process, due to improper operation, the forming block may be damaged, causing the forming block to crack and leak water and become unusable, and a new forming block needs to be re-invested. When the surface data of the forming block is used incorrectly, the newly made forming block cannot be used. 6. When the forming block needs to be re-invested at the place of origin of the mold shipment, if the mold is pulled back for overall surface processing, it will lead to an increase in mold transportation costs and processing costs, and also affect production efficiency. 7. When the mold is assembled and processed, the forming block first needs rough machining, and then multiple forming blocks are assembled together for overall processing. It requires a long cycle and a large gantry machining center, with slow time and high costs. Utility Model Content

[0023] Optionally, the boss is arranged close to the edge of the forming block.

[0024] By adopting the above technical solution, the convenience of measuring the height of the reference platform is further improved.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. During the process of mold opening and closing, the height of the reference platform will not be affected.

[0036] The following will Figures 1-4 further describe the present application in detail with reference to the attached

[0037] Embodiment 1

[0038] The embodiment of the present application provides a thermoforming mold with a reference platform, and its structure is as Figure 1 shown, including a mold 1 formed by assembling a plurality of forming blocks 11. Optionally, the forming blocks 11 can be steel blocks. A reference platform 2 is provided on the parting surface 12 of each forming block 11, and the height of the reference platform 2 is inconsistent with the height of the parting surface 12. This design enables the mold 1 not to wear the height of the reference platform 2 during the mold opening and closing process. By determining the height of the reference platform 2 and comparing the height of the reference platform 2 with the 3D data of the mold 1, the accuracy of the 3D data can be quickly and effectively judged. Therefore, when processing a new forming block 11, there is no need to remove the old forming block 11 for blue light scanning to make data comparison, and the new forming block 11 can be re-invested without affecting production, saving time, labor and economic costs.

[0039] Referring to Figure 1 and Figure 2, specifically, at least one groove 3 is provided on the parting surface 12, and the bottom surface of the groove 3 forms a reference platform 2. The design of the groove 3 facilitates processing and can provide good stability and practicability in actual applications. Optionally, the groove 3 can be processed during the finish machining of the mold 1 surface.

[0040] To further enhance the stability and machinability of the reference platform 2, the groove 3 penetrates the edge of the forming block 11. This not only makes the groove 3 easier to process but also facilitates the measurement of the height of the reference platform 2, further improving the data comparison efficiency. Optionally, tools such as vernier calipers can be used to quickly measure the height of the reference platform 2 without removing the forming block 11.

[0041] In the preferred embodiment, the cross-section of the groove 3 is designed as a U shape. This U-shaped groove 3 has a simple structure, is convenient for processing, and can provide a stable reference platform 2.

[0042] Refer to Figure 2 , in one embodiment, the groove 3 is provided between adjacent forming blocks 11, and the grooves 3 between the two forming blocks 11 can be combined to form a U-shaped groove 3. On the one hand, this can simplify the processing steps, and on the other hand, it can provide a clear positioning reference between adjacent forming blocks 11, which helps to ensure the accurate alignment during the assembly of the mold 1. In other embodiments, the cross-section of the groove 3 can also be designed as a circle or other shapes.

[0043] Refer to Figure 1 and Figure 3 , in another embodiment, a guide pin positioning hole 4 is also provided on the forming block 11, and the guide pin positioning hole 4 is communicated with the groove 3. This design can reduce the impact on the structural strength of the mold 1 and ensure the effective setting of the reference platform 2.

[0044] The implementation principle of Embodiment 1 of this application is as follows: During the debugging process of the forming block 11, when engraving needs to be reduced, the height of the reference platform 2 needs to be reduced simultaneously to ensure that the reference platform 2 is consistent with the surface. Later, during the process of checking data, by comparing the 3D data with the height of the reference platform 2 of the physical forming block 11, the accuracy of the surface data can be quickly and effectively confirmed. At the same time, in the new forming block 11 of this application solution, through data confirmation, the effect of assembly processing can be achieved by single-piece processing in place, which not only shortens the processing cycle but also saves labor and economic costs.

[0045] Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 lies in the formation method of the reference platform 2. Refer to Figure 3, specifically, at least one boss 5 is provided on each forming block 11, and the tabletop of the boss 5 forms a reference platform 2. Among them, the boss 5 can be a cylindrical boss or a conical boss, etc.

[0047] At the same time, a receiving groove (not shown in the figure) for the boss 5 to pass through is formed on another forming block 11 relative to the boss 5. This cooperative design of the boss 5 and the receiving groove prevents the boss 5 from being worn during the mold opening and closing process of the mold 1, ensuring the accuracy of the reference platform 2.

[0048] For the convenience of observation and measurement, the boss 5 is arranged at a position close to the edge of the forming block 11. At the same time, the surface of the reference platform 2 is finely processed to ensure that its flatness and perpendicularity meet the accuracy requirements.

[0049] In summary, the present application provides an effective solution for the mold 1 to confirm the surface data during the repair process by setting the reference platform 2 on the parting surface 12 of each forming block 11.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
