[0002] In the eyes of industry professionals, plastic and plastic are the same thing. With the rapid development of the plastics industry and the continuous improvement of plastic performance, plastic parts have been used more widely. Plastic parts are replacing traditional metal parts in different fields. A well-designed plastic part can often replace multiple traditional metal parts, thereby simplifying product structure and saving manufacturing costs.

[0003] Chinese utility model CN213227489U describes a molding device for producing plastic bottles, which includes a template disassembly structure. The principle is to pull the handle to disengage the mounting block from the mounting hole, thereby releasing the fixation of the support column and allowing the mold to be disassembled.

[0004] However, the existing device requires pulling the handle in two directions while simultaneously pulling the support column out of the placement slot, which requires multiple workers to complete and is a waste of manpower. Therefore, a molding device with easier disassembly was designed to address the above-mentioned problems. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The current technology works by pulling a handle to detach the mounting block from the mounting hole, thus releasing the support column and allowing the mold to be removed. However, existing devices require pulling the handle in two directions while simultaneously pulling the support column out of the placement slot, requiring multiple workers to operate, which is a waste of manpower.

[0028] like Figure 1-4As shown, this utility model embodiment provides a thermoforming device for plastic bottle production. The thermoforming device includes: a workbench 11 with a telescopic fan 12 mounted on its top; an electric push rod 13 mounted on the workbench 11; a heating mold 14 mounted at one end of the electric push rod 13; and a connecting assembly 2 at the connection between the electric push rod 13 and the heating mold 14. The connecting assembly 2 includes: a mounting block 21 mounted on one side of the heating mold 14; a positioning hole 22 formed on the top of the mounting block 21; and a rectangular shell. 23, located at one end of the electric push rod 13; upright plate 24, with its bottom end inserted into the interior of the rectangular shell 23; top plate 25, located at the top of the upright plate 24; insertion rod 26, located at the bottom of the top plate 25, with the bottom end of the insertion rod 26 penetrating through the outer wall of the rectangular shell 23 and inserted into the interior of the positioning hole 22; connecting rod 27, rotatably located on both sides of the bottom end of the upright plate 24; push rod 28, with one end inserted into the interior of the rectangular shell 23 and rotatably connected to the other end of the connecting rod 27; spring 29, with both ends connected to the push rod 28.

[0029] Specifically, this device requires the use of a conveying device, which is not shown in the attached drawings. The conveying device transports the plastic bottle to the center of the heating mold 14, where the heating mold 14 closes and heats the plastic bottle to soften it. Finally, a telescopic blower 12 connects its bottom outlet to the plastic bottle and introduces air into it. At this point, the outer wall of the plastic bottle adheres to the inner wall of the heating mold 14, thus blowing the round plastic bottle into a uniform size. The telescopic blower 12 consists of a blower and a telescopic air outlet for connecting with the plastic bottle. The heating mold 14 contains heating wires, and the temperature inside the heating mold 14 can be adjusted by controlling the resistance.

[0030] When the heating mold 14 needs to be disassembled, the push rod 28 can be pressed with the index finger and thumb and inserted into the rectangular shell 23. As the push rod 28 is inserted, it will drive the connecting rod 27 to rotate, and at the same time compress the spring 29. While the connecting rod 27 is rotating, it can push the upright plate 24 out of the rectangular shell 23, and at the same time push the top plate 25 to move upward, causing the insertion rod 26 to disengage from the positioning hole 22, thus releasing the restriction on the mounting block 21. At this time, the mounting block 21 can be separated from the rectangular shell 23 to complete the disassembly of the heating mold 14. After cleaning the plastic residue on the inside of the heating mold 14, press the push rod 28 in the above manner, and then insert the mounting block 21 into the rectangular shell 23. Then release the push rod 28, and the spring 29 will rebound and push the push rod 28 away, and drive the upright plate 24 to insert into the rectangular shell 23, causing the top plate 25 to move downward, so that the insertion rod 26 is inserted into the positioning hole 22 on the mounting block 21, thus completing the installation of the heating mold 14.

[0031] Furthermore, the inner wall of the rectangular shell 23 is fitted to the outer wall of the mounting block 21.

[0032] The design that fits snugly during use can better limit the shaking of the mounting block 21 after installation, thus making the installation more stable.

[0033] Furthermore, the connecting component 2 also includes a cone 261 disposed at the bottom end of the insertion rod 26.

[0034] The pointed design at the bottom of the cone 261 makes it easier to insert the rod 26 into the positioning hole 22 during use.

[0035] Furthermore, the connecting component 2 also includes a push plate 281, which is disposed at one end of the push rod 28.

[0036] The design of the push plate 281 increases the area of ​​one end of the push rod 28, making it more comfortable to press the push rod 28.

[0037] Furthermore, the connecting component 2 also includes a protrusion 282, which is disposed on one side of the push plate 281.

[0038] The design of the raised strip 282 during use increases friction when the finger comes into contact with the push plate 281.

[0039] Furthermore, the mounting block 21 is provided with a spring-loaded assembly 3, which includes: a groove 31, which is formed at one end of the mounting block 21; a second spring 32, which is disposed inside the groove 31; and a rod 33, one end of which is inserted into the groove 31 and connected to the second spring 32.

[0040] When in use, after the mounting block 21 is released from its fixation, the spring 2 32 rebounds and pushes the rod 33 out of the groove 31, causing the mounting block 21 to detach from the rectangular shell 23, thus improving the ease of disassembly.

[0041] Furthermore, the rebound assembly 3 also includes a rubber pad 34 disposed at one end of the rod 33.

[0042] When in use, the rubber pad 34 is designed to cushion the impact when one end of the rod 33 collides with the inner wall of the rectangular shell 23.

[0043] Furthermore, the rebound assembly 3 also includes: a crossbar 35, disposed inside the rod body 33, with one end passing through the inner wall of the rod body 33, passing through the second spring 32, and connecting to the inner wall of the groove 31; and a baffle 36, disposed at one end of the crossbar 35.

[0044] When in use, the crossbar 35 can limit the bending of the spring 32 when it is compressed, and the baffle 36 can prevent one end of the crossbar 35 from separating from the inside of the rod 33.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
