[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0025] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0026] This utility model provides a support mold for cutting plastic cup lids, such as... Figs. 1 to 3 As shown, it includes a support plate 1, the surface of which is provided with a protrusion 11 for supporting a plastic cup lid, the outer wall of the protrusion 11 is provided with a groove 12 corresponding to the cutting blade, the surface of the support plate 1 is provided with a conductive coating 13, the conductive coating 13 corresponds to the plastic to be cut, and the conductive coating 13 is electrically connected to an electrostatic generator (not shown in the figure) so that the conductive coating 13 generates electrostatic adsorption to attract the plastic to be cut.

[0027] In this embodiment, the support plate 1 serves as the base of the mold and is used to support various forces during the cutting process; the protrusion 11 is used to precisely support the plastic cup lid and ensure the stability of the cup lid's position during cutting; the cutting groove 12 corresponds to the cutting blade and ensures that the cutting blade can accurately cut into the plastic cup lid to complete the cutting action; the electrostatic generator is electrically connected to the conductive coating 13 to generate an electrostatic field, causing the conductive coating 13 to generate electrostatic adsorption force. The conductive coating 13 has good conductivity and electrostatic adsorption capacity, which can effectively adsorb the plastic cup lid and prevent it from moving.

[0028] By adopting the above technical solutions, the stability and precision of the plastic to be cut during the cutting process can be effectively improved, displacement during cutting can be avoided, and the quality of the finished product can be guaranteed.

[0029] It should be noted that the electrostatic generator is existing technology, and those skilled in the art should be clear about its structure, principle and usage, etc., which will not be described in detail here.

[0030] In this embodiment, the blade groove 12 is configured as a ring structure, and a wiping sponge 121 is disposed inside the blade groove 12, corresponding to the cutting blade. The blade groove 12 is used to accommodate the ring-shaped cutting blade to ensure the completion of the cutting action. When the cutting blade descends to cut the plastic, it enters the blade groove 12, and the wiping sponge 121 can effectively remove plastic fragments or debris remaining on the cutting blade, preventing these residues from affecting the subsequent cutting effect.

[0031] In the embodiment, the two groups of the erasing sponges 121 are fixed to the inner wall and the outer wall of the knife groove 12 respectively, so that the cutting knife is clamped between the two groups of the erasing sponges 121, the cleaning effect is better, and the cutting quality and precision are improved.

[0032] In other embodiments, the erasing sponges 121 can be made of high-density sponge, rubber or other materials with good cleaning effect and wear resistance.

[0033] In the embodiment, the support plate 2 is further included, the bearing plate 1 is detachably connected with the support plate 2, and the support plate 2 is slidably installed on the rack 3.

It should be noted that the mold is slidably installed on the rack 3, and the structure, principle and use method thereof are clear to those skilled in the art, and will not be described in detail here.

[0034] In the embodiment, the support plate 2 supports the bearing plate 1 and the entire cutting process, and the bearing plate 1 is detachably connected with the support plate 2, so that the bearing plate 1 can be conveniently replaced and repaired without disassembling the entire mold.

[0035] In the embodiment, the magnetic attraction structure 4 is further included, the magnetic attraction structure 4 includes the first magnet 41 and the second magnet 42 which are magnetically attracted to each other, the first magnet 41 is located on the support plate 2, and the second magnet 42 is located on the side end face of the bearing plate 1 facing the support plate 2. When the bearing plate 1 needs to be installed on the support plate 2, the bearing plate 1 is only needed to be close to the support plate 2, so that the first magnet 41 and the second magnet 42 are in contact with each other. Due to the magnetic attraction between the first magnet 41 and the second magnet 42, they will be quickly adsorbed together, so as to firmly fix the bearing plate 1 on the support plate 2. This magnetic attraction connection method is quick and convenient, and does not need to use additional fasteners or tools.

[0036] In other embodiments, the first magnet 41 can be set as an electromagnet, and the second magnet 42 can be set as a permanent magnet or an electromagnet. The first magnet 41 generates a magnetic field to attract the second magnet 42 by electrification. Through the electrification magnetic attraction, the bearing plate 1 can be quickly fixed on the support plate 2, and can also be quickly released.

[0037] In the embodiment, the limit groove 14 is arranged on the side end face of the bearing plate 1 facing the support plate 2, the second magnet 42 is located in the limit groove 14, and the first magnet 41 is detachably embedded with the limit groove 14, so that the firm connection between the bearing plate 1 and the support plate 2 can be further ensured, thereby improving the overall structural stability of the mold.
