Description

Technical Field

[0001] The present invention relates to the technical field of silicone pad processing devices, and more specifically, to a silicone pad processing device. Background Art

[0002] As an environmentally friendly raw material, silicone is loved by the majority of people for its various superior properties. Among them, silicone pads are generally manufactured using solid-state hot pressing technology. During the processing, the temperature and pressure of the hydraulic press are generally used to vulcanize the product with the help of the mold. Silicone pads are widely used in electronics, industry, and home due to their excellent properties. Existing silicone pad processing devices such as CN219838125U pull-out silicone processing mold, which includes making silicone products through a pull-out mold, usually fixing the mold inside an injection molding machine, and then filling the silicone stock liquid into the mold cavity through the injection molding machine, and opening the mold after the silicone stock liquid is cooled and formed, and then taking out the silicone product. However, after the inventors have made efforts, they found that the existing pull-out silicone processing mold needs to quickly cool the silicone stock liquid inside the mold cavity after injection molding, but the current pull-out silicone processing mold usually adopts natural ventilation cooling, resulting in a relatively slow cooling speed of the mold, thereby affecting the production efficiency of silicone products; However, the existing silicone pads need to be manually arranged and placed into different cavities of the mold after the silicone pads are cut into sheets. When the silicone pad products are taken out of the mold, the silicone will stick to the mold cavity, and the silicone pads that have been vulcanized and hot-pressed into a specific shape need to be manually taken out, so that personnel need to be exposed under the press for a long time. The efficiency of silicone pad removal is low and the risk of personnel operation is relatively high. Summary of the invention

[0005] Furthermore, the lower end of the push rod is arranged to be arc-shaped and convex, and the edge extends outward, and return springs are arranged on both sides of the outside of the push rod.

[0006] Furthermore, the inclined block is arranged in a trapezoidal shape with inclined sides, and the inclined surface at the upper end of the inclined block is close to the bottom of the top rod.

[0007] Furthermore, support plates are provided on the front and rear sides of the top of the inclined block, the support plates correspond to the hinged connection pieces, and the shaft body inside the hinged connection piece extends outwards and penetrates into the support plates.

[0009] Furthermore, the limiting slide groove is arranged to extend transversely, and the outer end of the limiting slide rod enters the limiting slide groove and fits with the inner wall of the limiting slide groove when it is outward. Beneficial Effects

[0010] A silicone pad processing device has the following beneficial effects: 1. An upper mold is connected after the lower end of the first telescopic rod passes through the interior of the support frame, and positioning rods are arranged at the four corners of the upper end of the upper mold. The upper ends of the positioning rods penetrate into the interior of the support frame, and a first lower mold and a second lower mold are installed inside the device base corresponding to the lower end of the upper mold. The lower ends of the first lower mold and the second lower mold are rotatably connected through a hinged connector, and mold grooves are arranged at the upper ends of the first lower mold and the second lower mold. The mold grooves are evenly arranged at equal distances on the first lower mold and the second lower mold. After the semi-finished silicone pad is placed in the lower mold, the upper mold is driven downward by the first telescopic rod to complete the vulcanization and hot pressing processing of the silicone pad, and the first lower mold and the second lower mold are connected by a hinged connector. Therefore, after the processing of the silicone pad is completed, the two lower molds can be rotated to both sides to form an inclined shape, so that the silicone pad at the upper end falls out and then slides downward into the receiving groove, thereby completing the automatic discharge of the silicone pad.

[0011] 2. A top plate is installed at the bottom of the inner side of the mold groove, and a top rod is connected to the lower end of the top plate. The lower end of the top rod extends downward and passes through the inside of the mold groove. The lower end of the top rod is an arc-shaped convex setting, and the edge extends outward. Reset springs are arranged on both sides of the outside of the top rod. A second telescopic rod is installed at the lower end of the inner part of the device base. The second telescopic rod is arranged between the first lower mold and the second lower mold. An inclined block is connected to the upper end of the second telescopic rod. The inclined block is a trapezoidal setting with inclined sides. The inclined surface of the upper end of the inclined block is close to the bottom of the top rod. Support plates are arranged on the front and back sides of the top of the inclined block. The support plate corresponds to the hinged connector. The shaft body inside the hinged connector extends outward and penetrates into the inside of the support plate. When the second telescopic rod drives the inclined block to move upward, the support plate can drive the hinged connector to move upward. After the first lower mold and the second lower mold form an inclined state, the bottom of the top rod can contact the upper end of the inclined block, so that the top rod can squeeze the reset spring to drive the top plate to move upward in the mold groove, and the silicone pad inside it moves upward and leaves the inside of the mold groove, thereby completing the effect of automatic discharge.

[0012] 3. A pulling rod is installed at the interval between the first lower mold and the upper mold groove of the second lower mold, and a slide groove for the pulling rod to move is arranged at the upper ends of the first lower mold and the second lower mold. One end of the pulling rod extends outward and bends downward, and the two sides of the downward bent end of the pulling rod are connected with limiting slide bars, and the outer end of the limiting slide bar contacts the inner wall of the accommodating groove, and the inner wall of the accommodating groove is provided with a limiting slide groove with the same height as the limiting slide bar. The limiting slide groove is extended horizontally, and the outer end of the limiting slide bar enters the interior of the limiting slide groove and fits with the inner wall of the limiting slide groove when it goes out. Then, when the first lower mold and the second lower mold are in an inclined state, the limiting slide bar can be moved in the limiting slide groove, and the upper side of the end of the pulling rod away from the limiting slide bar is connected A scraper is connected, and the bottom of the scraper is close to the upper end surfaces of the first lower mold and the second lower mold. The scraper is arranged in a long triangular shape, and the inclined side of the scraper faces the mold groove. A groove matching the shape of the scraper is arranged at the bottom of the upper mold. The pulling rod is located on both sides of the first lower mold and the second lower mold, and limiting protrusions are arranged. The first lower mold and the second lower mold are provided with sliding grooves matching the limiting protrusions. As the rising height of the inclined block increases, the inclination of the first lower mold and the second lower mold increases, the pulling rod can be pulled outward, which actually drives the scraper to move at the upper end of the first lower mold and the second lower mold, and scrapes off the silicone pad ejected by the top plate, thereby preventing the silicone pad from sticking to the top plate.

Positioning rods 4 are provided at the four corners of the upper end of the upper mold 5. The upper ends of the positioning rods 4 penetrate into the interior of the support frame 2. A first lower mold 6 and a second lower mold 7 are installed inside the device base 1 corresponding to the lower end of the upper mold 5. The lower ends of the first lower mold 6 and the second lower mold 7 are rotatably connected through a hinged connector 16. A mold groove 8 is provided at the upper ends of the first lower mold 6 and the second lower mold 7. The mold grooves 8 are evenly arranged on the first lower mold 6 and the second lower mold 7 at equidistant intervals. After the semi-finished silicone pad is placed in the lower mold, the upper mold 5 is driven downward by the first telescopic rod 3 to complete the vulcanization and hot pressing processing of the silicone pad, and the first lower mold 6 and the second lower mold 7 are connected through the hinged connector 16. The two lower molds are connected, so that when the processing of the silicone pad is completed, the two lower molds can be rotated to both sides to form an inclined shape, so that the silicone pad at the upper end falls out and then slides down into the receiving groove 101, completing the automatic discharge of the silicone pad, and then a top plate 13 is installed through the bottom of the inner side of the mold groove 8, and the lower end of the top plate 13 is connected to a push rod 1301, and the lower end of the push rod 1301 extends downward to pass through the inside of the mold groove 8.
