Description

Technical Field

[0001] This utility model relates to the field of silicone pad hot pressing production technology, specifically to an environmentally friendly automatic production equipment for insulating silicone pads. Background Technology

[0002] Silicone pads are a type of silicone product with high market demand. They have certain tensile strength, flexibility, excellent insulation, pressure resistance, high temperature resistance, low temperature resistance, chemical stability, environmental friendliness, safety, and no odor. They are a highly active green product. When manufacturing silicone pads, the fabric with a silicone layer is placed in a mold and then hot-pressed using a hot press. Different mold specifications are used depending on the shape and size of the hot-pressed product.

[0003] As shown in the reference case "A Hot Press Device for Silicone Pad Production" (Announcement No. CN222290809U), the operator installs the mold body on the workbench surface using a convenient disassembly and assembly mechanism, places the silicone pad into the mold body, and then starts the hydraulic rod and hot press, causing the hot press to descend and hot press the silicone pad inside the mold body. After hot pressing, the silicone pad inside the mold body is cooled by a cooling mechanism, and finally the mold body is pushed out by a pushing mechanism. The convenient disassembly and assembly mechanism allows for quick disassembly and assembly of the mold body, resulting in high replacement efficiency and strong practicality.

[0004] However, during the actual hot pressing process, the silicone material becomes more fluid when heated, and often sticks or hangs on the inner wall of the mold cavity due to pressure distribution or residue issues. Especially during the mold demolding process, thin layers of residue are easily left on the corners or recessed areas of the mold cavity, which not only affects the surface cleanliness of the mold for repeated use, but may also affect the edge quality and dimensional consistency of the next batch of molded products.

[0005] Based on this, this utility model designs an environmentally friendly automatic production equipment for insulating silicone pads to solve the above problems. Utility Model Content

[0015] Furthermore, a spring is fitted on the outer side of the movable rod, and the two ends of the spring are fixedly connected to the fixed frame and the guide plate, respectively.

[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. The demolding component is set at the bottom of the processing base. After the silicone pad is hot-pressed and formed, it can be quickly ejected, reducing the adhesion to the mold groove. At the same time, the demolding component can scrape and clean the inner wall of the mold groove during the ejection process, effectively removing residual silicone and impurities. After the ejection and cleaning are completed, the reset component can realize the automatic reset of the structure, ensuring the stability and continuity of the demolding component in the cycle operation.

[0017] 2. With the cooperation of the guide plate, the movable rod can slide stably up and down inside the conveying trough.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0028] In some embodiments, please refer to the accompanying drawings. Figures 1-5 An environmentally friendly automated production line for insulating silicone pads, comprising, for example: Figure 1 As shown, the environmentally friendly automatic production equipment for insulating silicone pads in this embodiment includes a base 100 and a hot press table 200. The hot press table 200 is fixedly installed on the top of the base 100, and a hot press machine 210 is fixedly installed on the top of the hot press table 200. A production demolding mechanism 300 is used for rapid demolding of the silicone pad after hot pressing. The production demolding mechanism 300 is disposed on the top of the hot press table 200. The production demolding mechanism 300 includes a processing seat 310 disposed on the top of the hot press table 200. A demolding component 320 for rapid demolding is disposed at the bottom of the processing seat 310. A reset component 330 is disposed inside the demolding component 320.

[0029] In a preferred embodiment of this utility model, the demolding component 320 is located at the bottom of the processing base 310. It can assist in ejecting the silicone pad after the silicone pad is hot-pressed, reducing the adhesion between the silicone pad and the mold groove, effectively avoiding problems such as product edge pulling and deformation caused by adhesion, and significantly improving demolding efficiency and yield. While completing the ejection action, the demolding component 320 can also use its surface structure to simultaneously scrape the inner wall of the mold groove, cleaning up residual silicone, edge material or attached impurities, avoiding the problem of dirt accumulation in the multi-round molding process, and improving the cleanliness of the mold cavity. The reset component 330 inside the demolding component 320 can accurately reset the demolding component 320 after the demolding and cleaning actions are completed, ensuring that the structure can maintain the initial state in subsequent cycles and has good automatic cycle operation characteristics.

[0030] It should be noted that the hot press 210 includes a heating plate fixedly installed on the top of the hot press table 200, a temperature control component, a hydraulic drive device, and a press head structure for controlling the up and down movement.

[0031] The heating plate can provide a stable and adjustable heating temperature to the silicone layer inside the mold, ensuring that the silicone pad is cured and molded under the set pressure and temperature.

[0032] The hydraulic drive unit is responsible for driving the press head to reciprocate up and down, so as to apply uniform pressure to the silicone layer;

[0033] The demolding component 320 and the reset component 330 are both located inside the processing seat 310 at the top of the hot press table 200, and their movement paths are limited by the stage space after the mold forming is completed. They do not conflict with the pressure head stroke of the hot press machine 210, nor do they interfere with the heating and pressurizing operations during the hot pressing process.

[0034] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the demolding assembly 320 includes a support base 322 fixedly installed between the processing base 310 and the hot press table 200. The top of the processing base 310 is provided with a processing groove 321. The processing base 310 and the support base 322 are provided with a connecting conveying groove 323. One side of the conveying groove 323 is connected to the processing groove 321. A moving plate 326 is slidably installed inside the processing groove 321. A high-pressure pump 324 is fixedly installed on one side of the support base 322. The output end of the high-pressure pump 324 is connected to the conveying groove 323.

[0035] In a preferred embodiment of this utility model, the processing groove 321 is used for hot pressing of the silicone pad. The high-pressure pump 324 injects compressed gas or liquid medium into the conveying groove 323, thereby pushing the moving plate 326 located inside the processing groove 321 to move vertically, so as to uniformly lift the bottom of the silicone pad and assist it to demold from the mold cavity. The demolding action is initiated immediately after the hot pressing is completed to avoid the silicone pad from sticking and deforming due to insufficient cooling, thereby improving demolding efficiency and product integrity.

[0036] A scraper ring 328 is fixedly installed on the outer side of the movable plate 326, and the top edge of the inner ring of the scraper ring 328 is set as a bevel.

[0037] As a preferred embodiment of this utility model, the scraper ring 328 can move synchronously upwards while closely adhering to the inner wall of the processing groove 321 during the lifting process of the moving plate 326. The inclined structure can form a scraping angle of gradual contact during the contact process, effectively scraping away the residual silicone impurities adhering to the inner wall of the processing groove 321.

[0038] The bottom of the movable plate 326 is provided with multiple guide grooves 329. The adjacent sides of the multiple guide grooves 329 are connected to the conveying groove 323, and the opposite sides of the multiple guide grooves 329 are located on the inner ring side of the scraper ring 328.

[0039] In a preferred embodiment of this utility model, multiple guide grooves 329 ensure that the gas supplied by the high-pressure pump 324 in the conveying groove 323 is accurately guided along the guide grooves 329 to the inner area of ​​the scraper ring 328 after demolding. During the demolding process, the scraper ring 328 scrapes off the adhering impurities on the inner wall of the processing groove 321 into its inner concave ring. The guide grooves 329 guide the gas to form a directional airflow, which cleans the impurities in this area by air blowing, effectively preventing impurity residue or accumulation.

[0040] Multiple sealing blocks 3210 are fixedly installed on the inner bottom wall of the processing groove 321. The multiple sealing blocks 3210 are all located on one side of multiple guide grooves 329, and one side of each of the multiple sealing blocks 3210 extends into the interior of the corresponding guide groove 329.

[0041] In a preferred embodiment of this utility model, when the moving plate 326 is in the initial downward state, it effectively seals the guide groove 329 to prevent gas leakage or accidental blowing during the non-cleaning stage, thus ensuring the stability of the hot pressing processing environment. When the moving plate 326 moves upward during the demolding action, the multiple guide grooves 329 disengage from the sealing block 3210, and the guide grooves 329 can then connect with the conveying groove 323 to form a smooth airflow channel, thereby enabling timely removal of impurities from the inside of the scraper ring 328.

[0042] A baffle plate 327 is fixedly installed on the top of the movable plate 326, and the baffle plate 327 is slidably connected to the inner wall of the guide groove 329.

[0043] As a preferred embodiment of this utility model, the shielding plate 327 can shield the moving plate 326 and the scraper ring 328, effectively isolating the high temperature or residual silicone material inside the processing groove 321 from contaminating the moving structure during hot pressing or demolding cleaning, and preventing impurities from adhering to the guide groove 329 or the scraper ring 328, affecting its sliding accuracy and cleaning effect.

[0044] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the reset assembly 330 includes a fixed frame 331 fixedly installed inside the conveying trough 323. A movable rod 325 is slidably installed on the surface of the fixed frame 331. The top end of the movable rod 325 is fixedly connected to the bottom of the movable plate 326. A guide plate 332 is fixedly installed at the bottom end of the movable rod 325. The guide plate 332 is slidably connected to the inner wall of the conveying trough 323.

[0045] In a preferred embodiment of this utility model, the movable rod 325 can slide stably up and down inside the conveying groove 323 with the cooperation of the guide plate 332. When the high-pressure pump 324 stops supplying air, the movable rod 325 can drive the moving plate 326 to automatically move down and reset under its own weight, ensuring that the moving plate 326 can return to the initial position in a timely and accurate manner after each demolding and cleaning.

[0046] A spring 333 is sleeved on the outside of the movable rod 325, and the two ends of the spring 333 are fixedly connected to the fixed frame 331 and the guide plate 332 respectively.

[0047] In a preferred embodiment of this utility model, the spring 333 is in a compressed state during the demolding process. After the high-pressure pump 324 stops supplying air or releases pressure, it can quickly release elastic potential energy, drive the guide plate 332 to move downward, and then push the movable rod 325 and its connected movable plate 326 back to the initial position to complete the reset action.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
