[0028] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0029] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.

[0030] Combination Figure 1-Figure 6 As shown, a silicone molding mold in this embodiment includes a base 100 with an installation cavity 280, a mold is placed on the upper end surface of the base 100, and the mold includes a lower mold 510 and an upper mold 500 that cooperate with each other. U-shaped limit plates 110 are relatively provided on the upper end surface of the base 100, and the limit plates 110 are close to each other for clamping and fixing the mold. A driving component for driving the limit plates 110 to move closer to or away from each other is provided in the installation cavity 280, and a locking component 130 for locking the driving component is provided on one side wall of the base 100.

[0031] In actual use of this embodiment, the upper mold 500 is overlapped on the lower mold 510, and the lower mold 510 is placed on the base 100. Through the setting of the driving component, the driving component can drive the limiting plates 110 to approach each other to clamp and fix the mold, so as to achieve the fixed installation of the mold on the base 100; wherein, the limiting plates 110 are U-shaped, so that when the two limiting plates 110 approach each other, they can cover and limit the four sides of the mold, so as to achieve the fixation of the mold on the base 100;

[0032] The upper mold 500 can better fit the lower mold 510 due to its own weight. The upper side of the lower mold 510 is provided with an injection cavity 600 for holding molten silicone. The center of the lower end surface of the upper mold 500 is provided with a mold core 610 for shaping the silicone in the injection cavity 600. The upper end surface of the upper mold 500 is provided with an injection port 520 for injecting silicone into the mold. The upper end surface of the upper mold 500 is also provided with a vent hole 530 for ventilation. The base 100 is provided with a support frame 140. The support frame 140 is provided with a hopper 150 at a position above the injection port 520. The hopper 150 is used to store and transport molten silicone.

[0033] In actual use, the molten silica gel in the hopper 150 can enter the injection cavity 600 through the injection port 520 by setting the injection port 520 and the vent hole 530, and the pressure is released by the vent hole 530, so that the molten silica gel can enter the injection cavity 600 through the injection port 520; the mold core 610 is set to shape the molten silica gel in the injection cavity 600, wait for the molten silica gel in the injection cavity 600 to cool and solidify, and use the driving component to move the relative limit plates 110 away from each other, release the fixation of the mold, and remove the upper mold 500 from the lower mold 510, so as to obtain a molded silica gel part;

[0034] Among them, by moving the limiting plates 110 away from each other, the mold is released from the fixation, and then the mold can be removed from the base 100, which is convenient for disassembly and assembly of the mold on the base 100, making the disassembly and assembly process of the mold on the base 100 relatively simple, thereby facilitating the cleaning and replacement of the mold; it should be pointed out that the width of the replaced mold is adapted to the inner length of the limiting plates 110, that is, the limiting plates 110 are close to each other to fix the replaced mold;

[0035] Among them, through the setting of the locking component 130, when the driving component drives the limit plate 110 to approach each other to clamp the mold, the locking component 130 can lock the driving component, thereby preventing the driving component from malfunctioning, causing the limit plate 110 to release the fixation of the mold, thereby affecting the molding operation of the mold.

[0036] Combination Figure 2-Figure 4 As shown, in this embodiment, a sliding groove 120 connecting to the installation cavity 280 is provided on the upper end surface of the base 100 along its length direction; the driving component includes a rotating rod 200 rotatably arranged in the installation cavity 280, the rotating rod 200 is arranged along the length direction of the installation cavity 280, and a movable plate 230 is relatively provided on the rotating rod 200, and the movable plate 230 passes through the sliding groove 120 and is connected to the corresponding limit plate 110, and the rotating rod 200 is threaded through the movable plate 230, and the rotation of the rotating rod 200 is used to realize the limit plates 110 approaching or moving away from each other.

[0037] In actual use of this embodiment, both ends of the rotating rod 200 are rotatably installed in the installation cavity 280 through the bearing seat 250 to achieve the rotatable installation of the rotating rod 200;

[0038] In actual use, the rotating rod 200 is provided with symmetrical and opposite threads, and at the same time, the sliding groove 120 can limit the movable plate 230, so that the rotating rod 200 can rotate to drive the two movable plates 230 to move closer to or away from each other on the rotating rod 200;

[0039] When the rotating rod 200 rotates, the moving plate 230 drives the limiting plates 110 to move closer to each other, so as to achieve clamping and fixing of the mold. When the rotating rod 200 rotates in the opposite direction, the moving plate 230 drives the limiting plates 110 to move away from each other, so as to achieve releasing and fixing of the mold.

[0040] Among them, by setting the sliding groove 120, the moving plate 230 can slide along the side wall of the sliding groove 120, and then the moving plate 230 can drive the limiting plate 110 to slide along the side wall of the sliding groove 120, so that the sliding groove 120 can limit the moving plate 230, so that the rotation rod 200 drives the limiting plate 110 to move more smoothly;

[0041] In actual use, a sliding block 220 is provided on the lower side of the moving plate 230, a long strip block 210 is provided on the bottom wall of the installation cavity 280 along its length direction, and a limiting groove 260 is provided on the upper end surface of the long strip block 210 along the moving direction of the moving plate 230, and the sliding block 220 extends into the limiting groove 260 and is slidably arranged;

[0042] In actual use, the long strip block 210 is connected to the lower side wall of the installation cavity 280 by welding. The welding connection increases the connection strength between the long strip block 210 and the bottom wall of the installation cavity 280, so that the sliding block 220 can slide better in the limiting groove 260. The limiting groove 260 can further limit the sliding block 220, so that the moving plate 230 can move more smoothly on the rotating rod 200.

[0043] Combination Figure 2-Figure 4As shown, in this embodiment, one end of the rotating rod 200 is arranged outside the base 100, and the locking assembly 130 includes a frosted ring 240, which is sleeved on the protruding end of the rotating rod 200, and a protrusion 300 is provided on the inner side wall of the frosted ring 240. A sliding groove 400 for the protrusion 300 to slide into is provided along the axial direction of the protruding end of the rotating rod 200, and a spring 270 is provided at the other end of the frosted ring 240. The spring 270 is sleeved on the protruding end of the rotating rod 200, and a gasket 410 is fixedly provided at the protruding end of the rotating rod 200. The spring 270 is used to push the frosted ring 240 to abut against the side wall of the base 100.

[0044] In actual use of this embodiment, a rubber pad is provided on one side of the frosted ring 240 facing the side wall of the base 100. The rubber pad is provided so that when the frosted ring 240 abuts against the side wall of the base 100 under the action of the spring 270, the rubber pad can fit against the side wall of the base 100, thereby increasing the friction between the side wall of the base 100 and the frosted ring 240, so that the frosted ring 240 is not easy to rotate when abutting against the side wall of the base 100. Even if the rotating rod 200 is not easy to rotate, the malfunction of the driving assembly caused by the malfunction of the rotating rod 200 is preferably avoided.

[0045] In actual use, the protrusion 300 is extended into the slide groove 400 and slidably arranged, so that the frosted ring 240 can slide on the rotating rod 200. At the same time, the frosted ring 240 can axially rotate on the rotating rod 200, so that the rotation of the frosted ring 240 drives the protrusion 300 to rotate axially, so that the protrusion 300 can abut against the side wall of the slide groove 400 and drive the rotating rod 200 to rotate;

[0046] The spring 270 and the gasket 410 are arranged so that the gasket 410 is fixedly mounted on the protruding end of the rotating rod 200, one end of the spring 270 abuts against the gasket 410, and the other end abuts against a side wall of the frosted ring 240, so that the spring 270 can push the frosted ring 240 to abut against the side wall of the base 100, thereby limiting the rotating rod 200. At the same time, the frosted ring 240 is separated from the side wall of the base 100, so that the rotation of the frosted ring 240 can drive the rotating rod 200 to rotate;

[0047] In this embodiment, a connecting rod 310 is provided on one side surface of the frosted ring 240 along its circumference. The connecting rod 310 is fixedly installed outside the spring 270. A fixing plate 320 is provided between one ends of the connecting rod 310. A handle 330 is provided on one side of the fixing plate 320. The handle 330 is convenient for the operator to pull or rotate the frosted ring 240. By pulling or rotating the frosted ring 240, the rotation or locking of the rotating rod 200 is achieved, making the operation simple and convenient.

[0048] Working principle: when it is necessary to use the molding mold to make silicone parts, the upper mold 500 is overlapped on the lower mold 510, and the locking assembly 130 cancels the lock on the rotating rod 200 by pulling the handle 330, and the rotating rod 200 is driven to rotate by turning the handle 330, driving the limit plates 110 to approach each other to clamp and fix the mold, and the handle 330 is released. The frosted ring 240 abuts against the side wall of the base 100 to lock the rotating rod 200, and the molten silicone in the hopper 150 is injected into the injection cavity 600 through the injection port 520. After waiting for cooling to form a silicone part, the locking assembly 130 cancels the lock on the rotating rod 200 by pulling the handle 330, and the rotating rod 200 is driven to rotate by turning the handle 330, thereby canceling the fixation of the mold, and the upper mold 500 is removed to obtain the molded silicone part. At the same time, the lower mold 510 can be removed to clean it for the next use.

[0049] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
