[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1 to 7 As shown, the silicone rubber production molding device 100 of this utility model includes an operating table 1, a molding box 2, a feeding component 3 for feeding silicone rubber raw materials into the molding box 2, a driving component 4 for driving the feeding component 3 to move closer to and away from the molding box 2, a pressing component 5 for pressing the material towards the molding box 2 and forming it, and a discharging component 6.

[0028] The molding box 2, feeding component 3, driving component 4, pressing component 5, and discharging component 6 are all mounted on the operating table 1, which is equipped with a controller 12. The operating table 1 is supported by support legs 11 to position the discharging component 6 at the bottom of the operating table 1.

[0029] In this embodiment, the molding box 2 is cubic in shape and has a material receiving groove 21. In other embodiments, the molding box 2 may also be of other shapes, such as cylindrical, as long as the pressing component 5 can press the material normally.

[0030] In this embodiment, there are two of each of the driving component 4 and the feeding component 3, which are respectively arranged on both sides of the molding box 2. This allows the silicone rubber raw material in the molding box 2 to be distributed more evenly by feeding from both sides.

[0031] The driving component 4 includes a first mounting bracket 41, a first push rod 42 disposed on the first mounting bracket 41, a first connecting rod 43 connected to the first push rod 42, and a sliding guide rail 44.

[0032] The first mounting bracket 41 is fixed on the operating table 1, and the first push rod 42 is used to push the first connecting rod 43 to move. In this embodiment, the first connecting rod 43 is used to move closer to or further away from the molding box 2.

[0033] The feeding component 3 includes a sliding inclined trough 31, a feeding slider 32 connected to the sliding inclined trough 31, a measuring cylinder 33 disposed above the sliding inclined trough 31, a support rod 34 connecting the feeding slider 32 and the sliding inclined trough 31, a fixed frame 35 connecting the measuring cylinder 33 and the sliding inclined trough 31, and sliding wheels 36 disposed on both sides of the sliding guide rail 44.

[0034] The feeding slider 32 is disposed within the sliding guide rail 44, and the first connecting rod 43 is connected to the feeding slider 32. The feeding slider 32 is movable within the sliding guide rail 44, thereby controlling it to move closer to or further away from the molding box 2 as needed.

[0035] The sliding inclined material groove 31 is inclined, with the lower end close to the molding box 2. After the silicone rubber raw material falls into the sliding inclined material groove 31, it slides down under the action of gravity and falls into the material receiving groove 21 of the molding box 2.

[0036] The sliding wheel 36 is connected to the feeding slider 32 to improve the stability of the movement of the feeding slider 32. In this embodiment, each feeding slider 32 is provided with four sliding wheels 36, which are respectively arranged on both sides of the feeding slider 32.

[0037] The support rod 34 lifts the sliding inclined trough 31. In this embodiment, each sliding inclined trough 31 is provided with two support rods 34, and the two support rods 34 are at different heights so that the sliding inclined trough 31 is inclined.

[0038] The fixed frame 35 is located at the higher end of the sliding inclined trough 31.

[0039] The bottom of the measuring cylinder 33 is provided with a discharge pipe 331 and an electric valve 332. The measuring cylinder 33 is provided with a position scale 333 for detecting the volume of silicone rubber raw material. In this embodiment, the measuring cylinder 33 is used to receive silicone rubber raw material and discharge it through the discharge pipe 331. The position scale 333 detects the volume of silicone rubber raw material in the measuring cylinder 33, and the electric valve 332 controls the discharge amount.

[0040] In this embodiment, the driving component 4 is connected to the sliding inclined material groove 31 to drive the sliding inclined material groove 31 to move closer to or away from the molding box 2. Furthermore, the driving component 4 drives the sliding inclined material groove 31 to move by driving the feeding slider 32 to move.

[0041] The molding chamber 2 is equipped with a distance sensor 23 for detecting the distance between the feeding slider 32 and the molding chamber 2. Material is fed when the sliding inclined groove 31 is close to the molding chamber 2, and molding is performed when it is far away from the molding chamber 2.

[0042] The pressing component 5 includes a second mounting bracket 51, a hydraulic cylinder 52 mounted on the second mounting bracket 51, a molding press 53 driven by the hydraulic cylinder 52 to move vertically, and a second connecting rod 54 connecting the hydraulic cylinder 52 and the molding press 53. The molding press 53 is equipped with a heating module 55. The molding press 53 is used to perform molding treatment on silicone rubber raw materials, and the heating module 55 can heat the silicone rubber raw materials to improve the molding effect.

[0043] The ejector component 6 includes a third mounting bracket 61 disposed at the bottom of the operating table 1, a second push rod 62 disposed on the third mounting bracket 61, a third connecting rod 63 connecting the second push rod 62, and a top plate 64 disposed at the top of the third connecting rod 63. Both the operating table 1 and the molding box 2 are provided with clearance holes 22 for the third connecting rod 63 and the top plate 64 to pass through. The third connecting rod 63 and the top plate 64 are used to protrude into the molding box 2. In this embodiment, the top plate 64 is used to eject the molded silicone rubber.

[0044] The controller 12 is equipped with a start button, a molding button and a buzzer. The controller 12 is electrically connected to the feeding component 3, the driving component 4 and the pressing component 5.

[0045] The working principle of this utility model is as follows: the distance sensor 23 is provided with a first threshold and a second threshold, and the value of the first threshold is smaller than the value of the second threshold.

[0046] The position scale 333 is set with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0047] Silicone rubber raw material is poured into the measuring cylinder 33. The position scale 333 measures the volume of the silicone rubber raw material, thereby controlling the amount of silicone rubber raw material used. When the volume of the silicone rubber raw material reaches the first threshold preset by the position scale 333, the buzzer sounds, and the pouring of silicone rubber raw material stops. Then, the start button is pressed, which controls the first push rod 42 to move the first connecting rod 43, thereby moving the feeding component 3 towards the molding box 2. The sliding wheel 36 maintains the stability of the sliding inclined material groove 31 during the sliding process. When the distance between the feeding slider 32 and the distance sensor 23 reaches the first threshold preset by the distance sensor 23, the first push rod 42 stops working, and at the same time, the electric valve 332 opens the discharge pipe 331 of the measuring cylinder 33. The silicone rubber raw material falls through the discharge pipe 331 of the measuring cylinder 33 onto the sliding inclined material groove 31, and then slides into the molding box 2 through the sliding inclined material groove 31, thus completing the automatic feeding operation.

[0048] When the volume of the silicone rubber raw material is lower than the second threshold preset by the position scale 333, the electric valve 332 is controlled to close the channel of the discharge pipe 331 of the measuring cylinder 33. At the same time, the first push rod 42 is controlled to drive the first connecting rod 43 and the feeding component 3 to move away from the molding box 2. When the distance between the sliding inclined groove 31 and the distance sensor 23 reaches the second threshold preset by the distance sensor 23, the first push rod 42 is controlled to stop working.

[0049] Pressing the molding button controls the hydraulic cylinder 52 to lower the second connecting rod 54 and the molding press 53. The molding press 53 performs molding work on the silicone rubber material in the molding box 2. During the molding process, the heating module 55 heats the silicone rubber material to improve the molding efficiency. After the silicone rubber molding is completed, the hydraulic cylinder 52 drives the second connecting rod 54 and the molding press 53 to rise to the reset position.

[0050] After the silicone rubber cools, the second push rod 62 drives the third connecting rod 63 and the top plate 64 to rise, so that the top plate 64 gradually pushes the silicone rubber out of the molding box 2, thereby removing the silicone rubber. Then the silicone rubber is moved away, and then the second push rod 62 drives the third connecting rod 63 and the top plate 64 to descend to the reset position.

[0051] The molding device 100 for silicone rubber production of this utility model achieves precise control of the amount of silicone rubber raw material used during processing by setting a position scale 333. In conjunction with the electric valve 332, it can automatically feed the silicone rubber raw material, reducing processing steps and improving production efficiency.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
