Description

Technical Field

[0001] This application relates to the field of cutting thermoformed products, and in particular to a lower mold and a cutting mold for processing thermoformed products. Background Technology

[0002] Currently, for some blister products (such as plastic packaging boxes), they need to be formed by blister molding and then cut by die cutting.

[0003] In related technologies, such as Figure 1 The cutting mold shown includes an upper mold 1 and a lower mold 2. The thermoformed product is placed in the lower mold 2. The upper mold 1 is close to the lower mold 2 to cut off the edge waste of the thermoformed product. Then the upper mold 1 moves away from the lower mold 2 to take away the cut waste to ensure the continuity of subsequent cutting work.

[0004] However, in practical applications, as the upper mold moves away from the lower mold, it sometimes carries away the cut blister product, causing the blister product to shift or even be damaged, resulting in poor processing quality. Therefore, improvements are needed. Utility Model Content

[0005] In order to improve the processing effect of thermoformed products, firstly, this application provides a lower mold.

[0006] This application provides a lower mold with the following technical solution: A lower mold includes a lower mold base, a suction cup, and a vacuuming component. The upper side of the lower mold base has a placement groove, and the bottom wall of the lower mold base located in the placement groove has an installation groove. The lower mold base has a venting groove, and the venting groove is connected to the installation groove. The suction cup is disposed in the installation groove. The vacuuming component is connected to the venting groove.

[0007] By adopting the above technical solution, in practical applications, the thermoformed product is placed in the placement groove, and at the same time, the vacuum component works to evacuate the ventilation groove so that the suction cup installed in the installation groove can adsorb the thermoformed product after cutting, effectively reducing the thermoformed product from being carried away, minimizing the displacement or damage of the thermoformed product, thereby improving the processing effect of the thermoformed product.

[0008] Preferably, there are multiple placement slots, ventilation slots, and suction cups. The multiple placement slots are evenly spaced along the length and width directions of the lower mold base. Each ventilation slot and each suction cup is matched with each placement slot, and the multiple ventilation slots are connected to each other.

[0009] By adopting the above technical solution and setting multiple placement slots, ventilation slots and suction cups, multiple blister products can be cut simultaneously, thereby improving cutting efficiency.

[0010] Preferably, the lower mold base is provided with a plurality of overlapping blocks on the bottom wall of the placement groove, and the plurality of overlapping blocks are arranged at intervals along the circumference of the placement groove.

[0011] By adopting the above technical solution and setting multiple overlapping blocks, the blister product overlaps with multiple overlapping blocks when placed in the placement slot, so that there is a gap between the suction cup and the blister product, so as to facilitate the subsequent detachment of the blister product.

[0012] Preferably, the lower mold further includes a mounting base and a spring. The mounting base is disposed in the mounting groove, and the suction cup is detachably connected to the mounting base. The mounting base has a sliding groove and a limiting groove on its periphery. The sliding groove is disposed along the length direction of the mounting base and extends to the lower end of the mounting base. The limiting groove is disposed at the upper end of the sliding groove and is disposed along the periphery of the mounting base. The lower mold base is located in the mounting groove and is provided with a limiting post. The limiting post is limited to the sliding groove or the limiting groove. The spring is disposed between the mounting base and the mounting groove to drive the mounting base to extend out of the mounting groove.

[0013] By adopting the above technical solution, and by setting a mounting base and a spring, the suction cup is installed on the mounting base, which is then inserted into the mounting groove. This causes the limiting post to be confined within the sliding groove. Pressing the mounting base downwards and rotating it further confins the limiting post within the limiting groove, thus enabling the suction cup to be installed. Simultaneously, by rotating the mounting base, the limiting post slides to the upper end of the sliding groove. Driven by the spring, the mounting base pops out of the mounting groove, facilitating its removal and thus enabling the suction cup to be installed and removed.

[0014] Preferably, the mounting base has an embedded groove at the end of the limiting groove away from the sliding groove.

[0015] By adopting the above technical solution, and by setting a groove, the limiting post is limited in the groove to restrict the rotation of the mounting base, thereby improving the stability of the mounting base installation.

[0016] Preferably, the lower end of the mounting base has an annular groove, and the upper end of the spring is disposed in the annular groove.

[0017] By adopting the above technical solution, and by setting an annular groove, the upper end of the spring is located in the annular groove, so as to realize the synchronous installation of the mounting base and the spring, and to limit the deformation of the spring, thereby improving the service life of the spring.

[0018] Preferably, the lower mold further includes a retaining ring, which is engaged with the lower end of the suction cup and abuts against the lower end of the mounting base.

[0019] By adopting the above technical solution, and by setting a retaining ring, which is engaged with the lower end of the suction cup and abuts against the lower end of the mounting base, a detachable connection between the suction cup and the mounting base can be achieved.

[0020] Secondly, this application provides a die for processing thermoformed products.

[0021] The technical solution for die-cutting in the processing of thermoformed products provided in this application is as follows: A die for processing thermoformed products includes the lower die described above.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In practical applications, the thermoformed product is placed in the placement groove, and at the same time the vacuum component works to evacuate the ventilation groove so that the suction cup installed in the installation groove can adsorb the thermoformed product after it has been cut. This effectively reduces the thermoformed product from being carried away and minimizes the displacement or damage of the thermoformed product, thereby improving the processing effect of the thermoformed product. 2. By setting a mounting base and a spring, the suction cup is installed on the mounting base, which is then inserted into the mounting groove, so that the limiting post is limited to the sliding groove. Pressing the mounting base down and rotating it further limits the limiting post to the limiting groove, thus realizing the installation of the suction cup. At the same time, by rotating the mounting base, the limiting post slides to the upper end of the sliding groove. Driven by the spring, the mounting base pops out of the mounting groove, making it easy to remove the mounting base, thereby facilitating the installation and removal of the suction cup. 3. By setting an annular groove, the upper end of the spring is located in the annular groove, which facilitates the synchronous installation of the mounting base and the spring, and can limit the deformation of the spring, thereby improving the service life of the spring.

[0025] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0026] This application discloses a lower mold.

[0027] Example 1: Reference Figure 2 and Figure 3 The lower mold 2 includes a lower mold base 21, a suction cup 22, and a vacuum pump (not shown in the figure). The lower mold base 21 is rectangular in shape, and a rectangular placement groove 211 is formed at the upper end of the lower mold base 21 for placing the thermoformed product. A mounting groove 212 is formed on the bottom wall of the lower mold base 21 located in the placement groove 211. The lower mold base 21 also has a venting groove 213, which is located directly below and connected to the mounting groove 212. The suction cup 22 is installed in the mounting groove 212. The vacuum pump is a vacuum pump connected to the venting groove 213 via a connecting pipe.

[0028] In practical applications, the thermoformed product is placed in the placement groove 211, with its edge overlapping the upper side of the upper mold 1. The upper mold 1 is close to the lower mold 2 to cut the edge of the thermoformed product. Simultaneously, the vacuum unit operates to create a vacuum in the ventilation groove 213, allowing the suction cup 22 installed in the mounting groove 212 to adsorb the cut thermoformed product. This effectively reduces the likelihood of the thermoformed product being carried away by the upper mold 1, minimizing displacement or damage, and thus improving the processing effect of the thermoformed product.

[0029] In some embodiments, there are multiple placement slots 211, which are evenly spaced along the length and width directions of the lower mold base 21. Correspondingly, the number of ventilation slots 213 and suction cups 22 is the same as the number of placement slots 211, and each ventilation slot 213 matches each suction cup 22 and each placement slot 211. The multiple ventilation slots 213 are interconnected, and the vacuuming component only needs to communicate with one of the ventilation slots 213. In this way, multiple thermoformed products can be cut simultaneously, improving cutting efficiency and thus increasing the processing efficiency of thermoformed products.

[0030] In some embodiments, the lower mold base 21 has a plurality of overlapping blocks 214 protruding from the bottom wall of the placement groove 211. The number of overlapping blocks 214 is four, and the four overlapping blocks 214 are evenly spaced along the circumference of the placement groove 211. When the blister product is placed in the placement groove 211, the blister product overlaps with the four overlapping blocks 214, creating a gap between the suction cup 22 and the blister product, facilitating subsequent detachment of the blister product. Furthermore, since the edge of the blister product overlaps with the upper side of the lower mold base 21 and the bottom of the blister product overlaps with the four overlapping blocks 214, the stability of the blister product placement is improved, thereby enhancing the cutting effect of the blister product.

[0031] The implementation principle of this embodiment is as follows: In practical applications, the thermoformed product is placed in the placement groove 211, with the edge of the thermoformed product overlapping the upper side of the upper mold 1. The upper mold 1 is close to the lower mold 2 to cut the edge of the thermoformed product. At the same time, the vacuum component operates to evacuate the ventilation groove 213, so that the suction cup 22 installed in the mounting groove 212 can adsorb the cut thermoformed product, effectively reducing the thermoformed product being carried away by the upper mold 1, minimizing the displacement or damage of the thermoformed product, thereby improving the processing effect of the thermoformed product.

[0032] Example 2: Reference Figure 4 , Figure 5 and Figure 6 This embodiment is identical to Embodiment 1 in all other structural aspects, except that the lower mold 2 further includes a mounting base 23 and a spring 24. The mounting base 23 is installed in the mounting groove 212, and the suction cup 22 is detachably connected to the mounting base 23. Specifically, the mounting base 23 has a sliding groove 231 and a limiting groove 232 on its circumference. The sliding groove 231 is arranged along the length of the mounting base 23 and extends to the lower end of the mounting base 23. The limiting groove 232 is located at the upper end of the sliding groove 231 and is arranged along the circumference of the mounting base 23.

[0033] Meanwhile, the lower mold base 21 protrudes from the mounting groove 212 to form a limiting post 215, which slides and is limited in the sliding groove 231 or the limiting groove 232. The upper end of the spring 24 elastically abuts against the mounting base 23, and the lower end elastically abuts against the bottom wall of the mounting groove 212, so as to drive the mounting base 23 to move upward, so that the mounting base 23 extends out of the mounting groove 212. Among them, the mounting base 23 partially protrudes out of the mounting groove 212.

[0034] In practical applications, after the suction cup 22 is installed on the mounting base 23, the mounting base 23 is inserted into the mounting groove 212, so that the limiting post 215 is limited to the sliding groove 231. Then, the mounting base 23 is pressed down, and the limiting post 215 slides to the upper end of the sliding groove 231. After that, the mounting base 23 is rotated, so that the limiting post 215 is limited to the limiting groove 232, thereby restricting the spring 24 from driving the mounting base 23 to move. This achieves the installation of the suction cup 22. At the same time, by rotating the mounting base 23, the limiting post 215 slides to the upper end of the sliding groove 231. Under the drive of the spring 24, the sliding post slides in the sliding groove 231, so that the mounting base 23 pops out of the mounting groove 212, thereby achieving the disassembly of the mounting base 23. The suction cup 22 is detachably connected to the mounting base 23, thus facilitating the installation and disassembly of the suction cup 22.

[0035] Reference Figure 6 In some embodiments, the mounting base 23 has a groove 233 facing downward at the end of the limiting groove 232 away from the sliding groove 231. By rotating the mounting base 23, the limiting post 215 slides to the end of the limiting groove 232 away from the sliding groove 231. Under the action of the spring 24, the limiting post 215 is embedded in the groove 233 to limit the rotation of the mounting base 23 and improve the stability of the mounting base 23.

[0036] In some embodiments, the lower end of the mounting base 23 is provided with an annular groove 234, and the upper end of the spring 24 is sleeved in the annular groove 234, so as to realize the synchronous installation of the mounting base 23 and the spring 24, and to limit the deformation of the spring 24, thereby improving the service life of the spring 24.

[0037] In some embodiments, the lower mold 2 further includes a retaining ring 25, the upper end of the suction cup 22 abuts against the upper end of the mounting base 23, and the retaining ring 25 is engaged with the lower end of the suction cup 22 and abuts against the lower end of the mounting base 23, so as to realize a detachable connection between the suction cup 22 and the mounting base 23, which is simple in structure and easy to operate.

[0038] This application also discloses a die-cutting method for processing thermoformed products.

[0039] The die-cutting process for thermoforming products includes the lower die described in the above embodiments.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
