[0004] In the above-mentioned patent disclosure, the hot cutting mechanism mainly drives the hot cutting knife toward the plastic part on the operating table through a hydraulic rod, and performs hot cutting operation on the plastic part to achieve cutting of the plastic part. However, in the actual hot cutting process of the plastic part, since the plastic parts have different shapes to meet the needs of use in different scenarios, the surface slopes of different plastic parts are not the same. When hot cutting different plastic parts, the plastic parts may deviate and slide during the breaking process due to the slope of the plastic parts, causing the cutting position of the plastic parts to deviate, resulting in a rough cut surface of the plastic part. Therefore, it is necessary to provide a plastic part hot cutting machine to solve the above problem.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] like Figure 1 As shown, the present application provides a plastic parts hot cutting machine, comprising a chassis 1, and a cutting table 11 arranged on the chassis 1, a mold table 12 is mounted on the cutting table 11, and the mold table 12 is used to place plastic parts;

[0022] A hot cutting mechanism 2 is provided on the chassis 1. The hot cutting mechanism 2 includes a cylinder 21 mounted on the top of the chassis 1 and a hanging plate 22 mounted on the output end of the cylinder 21. Guide posts 221 that pass through the chassis 1 are installed on both sides of the hanging plate 22. The guide posts 221 are suitable for sliding up and down in the chassis 1. The hanging plate 22 is driven up and down by the action of the cylinder 21, and the moving direction of the hanging plate 22 is limited by the cooperation of the guide posts 221.

[0023] At the same time, a hot cutter 23 is mounted on the hanging plate 22, wherein the hot cutter 23 is provided with a heating unit, which includes heating plates (not shown in the figure) mounted on both sides of the blade wall of the hot cutter 23. The heating plates are used to quickly heat the hot cutter 23, and the heating plates are located above the blade of the hot cutter 23. A temperature control device connected to the heating plates is mounted on the hanging plate 22. The heating unit is prior art. For details, please refer to Patent Publication No. CN208375791U, and no further details are given here.

[0024] like Figure 1-Figure 2As shown, a limiting mechanism 3 is provided at the bottom of the hanging plate 22, and the limiting mechanism 3 is used to press and position the plastic part. The limiting mechanism 3 includes a main plate 31 provided directly below the hanging plate 22, and a through slot 311 for the cutter 23 to pass through is provided on the main plate 31, so that the cutter 23 is suitable for passing through the through slot 311 to perform a hot cutting operation on the plastic part on the mold table 12, and a pressure plate 32 for pressing the plastic part is provided at the bottom of the main plate 31. The pressure plate 32 and the main plate 31 are an integrated structure, and a rubber sheet 321 for contacting the plastic part is installed at the bottom of the pressure plate 32 to prevent the pressure plate 32 from damaging the surface of the plastic part.

[0025] At the same time, four groups of evenly arranged elastic bodies 33 are provided between the hanging plate 22 and the main plate 31. The elastic bodies 33 are suitable for telescopic movement. The elastic bodies 33 include an elastic shaft 331 connected to the hanging plate 22 and a cylinder 332 provided outside the elastic shaft 331. The elastic shaft 331 is inserted into the cylinder 332 and is suitable for telescopic movement on the cylinder 332. A spring (not shown in the figure) connected to the bottom end of the elastic shaft 331 is installed in the cylinder 332. When the elastic shaft 331 is subjected to an external force, the elastic shaft 331 contracts toward the cylinder 332 and squeezes the spring. After the external force on the elastic shaft 331 disappears, the elastic shaft 331 is ejected toward the outside of the cylinder 332 and resets due to the action of the spring.

[0026] A joint 34 is provided between the bottom end of the cylinder 332 and the main plate 31. The joint 34 is used to connect the cylinder 332 to the main plate 31. The joint 34 consists of a bearing sleeve and a shaft head (not shown in the figure). The bearing sleeve is fixedly mounted on the main plate 31, and the shaft head is hinged in the bearing sleeve. The shaft head is adapted to deflect in different directions within the bearing sleeve, thereby making the shaft head suitable for universal adjustment. The joint 34 is a universal floating joint known in the prior art. For its specific structure, please refer to the prior art.

[0027] The bottom end of the cylinder 332 is connected to the shaft head of the joint 34. When the bottom of the pressure plate 32 receives a local external force, the joint 34 acts to cause part of the elastic body 33 to contract, thereby achieving the purpose of adaptive angle adjustment of the pressure plate 32.

[0028] When hot cutting of a plastic part is required, the plastic part is first mounted on the die table 12, and then the cylinder 21 drives the hanging plate 22 to approach the die table 12, and indirectly drives the limiting mechanism 3 to approach the plastic part. During the pressing process of the pressure plate 32 on the plastic part, the pressure plate 32 is locally subjected to a reaction force due to the influence of the inclined surface of the plastic part. At this time, under the action of the shaft head on the joint 34 and through the cooperation of the elastic body 33, the pressure plate 32 is tilted, and the pressure plate 32 is fitted to the surface of the plastic part. At the same time, under the elastic force of the elastic body 33, the pressure plate 32 presses the plastic part, and achieves the purpose of adaptively pressing and limiting different plastic parts.

[0029] Finally, the heating plate on the cutter 23 heats it, and the rear cylinder 21 drives the cutter 23 on the hanging plate 22 to pass through the through slot 311 to perform thermal cutting on the plastic part;

[0030] In summary, the pressure plate 32 is adapted to be adaptively tilted under the action of the shaft head on the joint 34, and with the cooperation of the elastic body 33, the pressure plate 32 applies pressure to the plastic part, thereby achieving the purpose of adaptively pressing and limiting different plastic parts, and solving the problem that the plastic part may be offset due to the influence of the inclined surface during the hot cutting process.

[0031] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any improvements and modifications that fall within the spirit and principles of the present application and do not depart from the principles of the present application shall be deemed to be within the scope of protection of the present application.
