Description

Technical Field

[0001] This utility model relates to the field of connector processing technology, specifically to a thermoforming device for precision connector plastic parts. Background Technology

[0002] The most common thermoforming equipment is the hot press. The hot press uses high temperature and pressure to heat and shape materials. It is often used to manufacture plastic products, rubber products, wood products, etc. It consists of a heating system, a pressure system and a control system. The working principle of the hot press is that the material heated on the heating plate softens or melts at a certain temperature, and then pressure is applied to press it into the required shape. When using plastic materials for connectors, thermoforming equipment can also be used for processing.

[0003] However, existing thermoforming equipment has certain shortcomings in use. The lack of proper internal protection due to the use of an insulated heating furnace body means that the internal heating equipment may be damaged under the downward pressure of the hydraulic press, thus affecting the thermoforming effect.

[0004] To solve the above problems, a thermoforming device disclosed in the prior art (Chinese patent application number CN202311151467.1, publication date 2024-05-24) can be referred to. This thermoforming device is characterized by a fixed connection between the top of a moving block and the bottom of a slider. When the heating plate is pressed down, the slider causes the moving block to move. The bottom rotating block of the moving block moves to the left, thereby causing the movable rod to move to the right along the mounting frame. The movable rod drives the lifting assembly to rotate, thereby lifting the device so that the top of the device contacts the bottom of the heating plate. This avoids excessive downward pressure that could cause the heating plate to be over-pressed and damaged, thus providing a protective support function.

[0005] Although the above-mentioned device can support and protect the heating plate, after the plastic is molded and cooled, demolding is required. The above-mentioned device only relies on cooling to achieve automatic demolding. Although it can demold, the efficiency is relatively low. The molded part may need to be removed manually, which may cause damage to the molded part.

[0006] Therefore, we proposed a thermoforming device for precision connector plastic parts, which can effectively solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 The present invention provides the following technical solution:

[0031] Example 1: For easier thermoforming processing, please refer to the attached document. Figure 1 -Appendix Figure 3The system includes a start / stop component 2 installed on one side of the fixed frame 1, an operating frame 3 fixed at the right end of the fixed frame 1, and a heating component 10 installed on the left side inside the fixed frame 1. It also includes a molding mechanism for processing heated plastic installed inside the operating frame 3. The molding component is slidably positioned at the upper end of the support member 9, and the support member 9 is slidably positioned at the top of the fixed frame 1. The output end of the heating component 10 acts on one end of the heating tube 12, and the heating tube 12 is fixed to the top inner side of the heat insulation frame 11. The heat insulation frame 11 has a groove inside to facilitate the sliding of the support member 9. A demolding mechanism is provided inside the right side of the fixed frame 1, and the ejector rod 18 included in the demolding mechanism is located below the support member 9. The molding mechanism includes a hydraulic drive component 4 installed at the top center of the operating frame 3. The output end of the hydraulic drive component 4 is fixed to the top of the moving block 5. The front and rear outer sides of the moving block 5 are slidably set inside the guide groove 6. The guide groove 6 is opened on the inner side of the operating frame 3. A mold body 7 for easy molding is fixed at the bottom of the moving block 5. A cooling component 8 is fixed at the top of the operating frame 3. The output end of the cooling component 8 acts on the outside of the mold body 7 to achieve the cooling effect. The mold body 7 is evenly spaced around the bottom of the moving blocks 5, and the moving blocks 5 form a sliding structure through the output end of the hydraulic drive component 4. For processing, a robotic arm places the plastic on top of the support component 9. Then, by rotating the rotating block 92, the rotating block 92 drives the bidirectional threaded rod 93 to rotate, causing the outer side of the bidirectional threaded rod 93 to move the threaded limiting plate 94. This allows the two sets of limiting plates 94 to move relative to each other, enabling the limiting plates 94 to position the plastic. Subsequently, by pushing the support component 9, it slides inside the heat insulation frame 11, allowing one end of the support component 9 to be conveyed to the heat insulation frame 11. 1. Then, the heating component 10 is started by controlling the start-stop component 2, so that the output end of the heating component 10 heats the heating tube 12, thereby heating the plastic inside the support 9. When the temperature reaches a suitable level, the support 9 can be slid back to the lower position of the operating frame 3. Then, the start-stop component 2 drives the hydraulic drive component 4 to work, so that the output end of the hydraulic drive component 4 can drive the moving block 5 to slide inside the guide groove 6, so that the mold body 7 fixed at the bottom of the moving block 5 is squeezed into the plastic, thereby molding the plastic. Then, the cooling component 8 is started to cool the inside of the mold body 7, which facilitates the molding process.

[0032] Example 2: To address the issue that current thermoforming machines require demolding after plastic molding and cooling, and the aforementioned device relies solely on cooling for automatic demolding, while this is efficient, it may require manual removal of the molded part, potentially causing damage. Please refer to the attached document. Figure 4 -Appendix Figure 6The support component 9 includes a movable plate 91. A rotating block 92 is rotatably mounted on one side of the movable plate 91. A bidirectional threaded rod 93 is fixed to the side of the rotating block 92. The end of the bidirectional threaded rod 93 is rotatably mounted inside the movable plate 91, and the outer side of the bidirectional threaded rod 93 is threadedly connected to the end of a limiting plate 94. The two sets of limiting plates 94 are arranged in opposite directions, and the limiting plates 94 are made of high-temperature resistant material. The inner side of the limiting plates 94 is attached to the outer side of the plastic. The demolding mechanism includes a swing rod 13 rotatably mounted on the outside of the fixed frame 1. The bottom of the swing rod 13 is rotatably mounted at the end of a rotating rod 14. A fixed rod 15 is fixed in the middle of the rotating rod 14. The top of the fixed rod 15 is rotatably mounted at the bottom of a connecting rod 16. The top of the connecting rod 16 is rotatably connected to the bottom of a connecting plate 17. The outer side of the connecting plate 17 is slidably mounted inside the fixed frame 1. The bottom of the push rod 18 corresponds to the bottom of the movable plate 91, and the push rod 18 forms a sliding structure with the interior of the fixed frame 1 through the connecting plate 17.

[0033] By continuously rotating the swing rod 13 back and forth, the bottom position of the swing rod 13 can drive the rotating rod 14 to rotate, and the fixed rod 15 rotating on the outside of the rotating rod 14 can rotate, which can drive the connecting rod 16 to rotate. This allows the connecting rod 16 to drive the connecting plate 17 to move, so that the ejector rod 18 can move back and forth inside the fixed frame 1. The top of the ejector rod 18 strikes the bottom of the support 9, causing the molded part to vibrate inside the mold body 7, thereby facilitating demolding.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
