In addition, after the existing molding device pours the liquid silicone into the mold, it is necessary to wait for the high-temperature silicone to cool naturally. The cooling time is long, and the molding time of the silicone buttons will be long, which affects the work efficiency. Therefore, we have made improvements on this and proposed a molding device for the production of silicone buttons." However, when the molding device in the above application is in use, the staff needs to manually demold the finished silicone buttons after die-casting. The finished silicone buttons are easily damaged during the manual demolding process, which is inconvenient for the staff to use. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The utility model provides a technical solution:

[0026] Embodiment 1

[0027] Combination Figures 1 to 4 A mold device for forming a silicone button includes a base 3, a die-casting mold 4 is fixedly connected to the top of the base 3, a die-casting mechanism 1 is arranged on the top of the die-casting mold 4, and a discharge mechanism 2 is arranged in the die-casting mold 4.

[0028] The die-casting mechanism 1 includes a support component 11 , a die-casting component 12 and a limit component 13 . The support component 11 is arranged on the top of the die-casting mold 4 , the die-casting component 12 is arranged inside the top of the support component 11 , and the limit component 13 is arranged outside the die-casting component 12 .

[0029] The support assembly 11 includes a support rod 1101, which is fixedly connected to the four corners of the top of the die-casting mold 4, and a frame plate 1102 is fixedly connected to the top of the support rod 1101. The die-casting assembly 12 includes an electric cylinder 1201, which is fixedly connected to the top of the frame plate 1102, and an electric telescopic rod 1202 is fixedly connected to the bottom of the electric cylinder 1201. A pressure plate 1203 is fixedly connected to the bottom of the electric telescopic rod 1202, and a protrusion 1204 is fixedly connected to the bottom of the pressure plate 1203. The limiting assembly 13 includes a fixed arm 1301, which is fixedly connected to the four inner corners of the top of the pressure plate 1203, and a ring 1302 is fixedly connected to the outside of the fixed arm 1301, and the outer ring of the ring 1302 is slidably connected to the outer ring of the support rod 1101.

[0030] Furthermore: the staff only needs to start the electric cylinder 1201 to drive the pressure plate 1203 and the protrusion 1204 downward through the electric telescopic rod 1202 to cooperate with the die-casting mold 4 to squeeze the raw materials into the material receiving groove 2101 and the button molding groove 2102 to complete the molding of the silicone button. The operation is simple and convenient for the staff to use. The design of the protrusion 1204 allows a cavity to be formed inside the silicone button after the button is molded, which increases the button rebound while reducing the raw material consumption of the finished product and reducing the cost of the finished product.

[0031] Embodiment 2

[0032] See also Figure 1, Figure 4 and Figure 5 On the basis of the first embodiment, it is further obtained that the discharging mechanism 2 includes a receiving component 21 and a discharging component 22, the receiving component 21 is arranged in the top of the die-casting mold 4, and the discharging component 22 is arranged in the die-casting mold 4.

[0033] The material receiving component 21 includes a material receiving groove 2101, which is opened in the top of the die-casting mold 4 at a position corresponding to the pressure plate 1203, and a button forming hollow groove 2102 is opened at the bottom of the material receiving groove 2101 corresponding to the position of the protrusion 1204. The material discharging component 22 includes a material ejecting barrel 2201, which is slidably connected to the die-casting mold 4, and the top of the material ejecting barrel 2201 and the bottom of the material receiving groove 2101 are at the same horizontal height. The bottom of the outer ring of the material ejecting barrel 2201 is fixedly connected to a limiting convex edge 2202, and the limiting convex edge 2202 is slidably connected to the die-casting mold 4. A movable slide groove 2203 is opened in the die-casting mold 4 corresponding to the position of the limiting convex edge 2202, and a compression spring 2204 is fixedly connected to the top of the material ejecting barrel 2201, and the compression spring 2204 is fixedly connected to the bottom of the movable slide groove 2203.

[0034] Furthermore: when the raw material is subjected to the downward pressure of the pressure plate 1203 and the protrusion 1204, the raw material will be squeezed downward in the material receiving groove 2101 into the button forming groove 2102, and the ejector barrel 2201 will be squeezed downward to the bottom simultaneously, so that the top of the ejector barrel 2201 and the bottom of the button forming groove 2102 are kept at the same horizontal plane. After the silicone button is die-cast, the pressure of the pressure plate 1203 and the protrusion 1204 is lost. At this time, the ejector barrel 2201 can move upward under the action of the compression spring 2204 to drive the silicone button finished product to demold upward by itself, without the need for manual demolding, thus avoiding possible damage during manual demolding and reducing the workload of the staff.

[0035] During the actual operation, when the device is used, the staff first places the raw material in the material receiving groove 2101, and then the staff starts the electric cylinder 1201. The electric cylinder 1201 starts to drive the pressing plate 1203 and the protrusion 1204 to move downward through the electric telescopic rod 1202. The pressing plate 1203 and the protrusion 1204 move downward to squeeze the raw material in the material receiving groove 2101 and completely penetrate into the key forming slot 2102. The raw material is squeezed into the key forming slot 2102 and pushes the ejector barrel 2201. Go down to the bottom, and then the raw material is completely flattened to complete the die-casting of the silicone button. Then start the electric cylinder 1201 to drive the pressure plate 1203 and the bump 1204 upward to break away from the contact with the raw material. At this time, the ejector barrel 2201 moves upward by itself under the action of the compression spring 2204. The upward movement of the ejector barrel 2201 drives the die-cast silicone button product to break away from the receiving groove 2101 and the button forming slot 2102 to complete demolding. After that, the staff can directly take the silicone button product for subsequent processing.
