[0027] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the drawings of the specification.

[0028] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments. The present utility model provides the following embodiments.

[0030] Such as Figures 1 to 8 , a silicone production and shaping mold includes: a movable mold 1, a fixed mold 2, a movable block 3, and a scraping mechanism 4. The lower surface of the movable mold 1 is attached to the fixed mold 2. The inner part of the movable mold 1 and the surface protrusions of the fixed mold 2 form a mold cavity. The inner part of the movable mold 1 is symmetrically and slidably connected with the movable block 3. An injection pipe is installed at the top of the movable block 3. A scraping mechanism 4 is installed inside the movable block 3 for cutting off the silicone injection liquid. The scraping mechanism 4 includes a movable scraper 41, a first lead screw 42, and a rotating disk 43. The movable scraper 41 is slidably installed at the bottom of the movable block 3 and passes through the inside of the movable block 3. The first lead screw 42 is rotatably connected to one side of the movable block 3 away from the injection pipe and passes through the inside of the movable block 3. The first lead screw 42 is threadedly connected to the movable scraper 41. The side of the first lead screw 42 away from the movable block 3 is fixedly connected to the rotating disk 43.

[0031] Furthermore, the scraping mechanism 4 further includes a limit block 44. The limit block 44 is fixedly connected to the inside of the movable block 3 and slidably penetrates through the movable scraper 41.

[0032] Furthermore, the scraping mechanism 4 further includes a circular through-hole 45. The surface of the movable scraper 41 is provided with the circular through-hole 45, and the diameter of the circular through-hole 45 is the same as that of the injection pipe of the movable block 3.

[0033] In this embodiment, the rotating turntable 43 is rotated to control the rotation of the first lead screw 42 inside the movable block 3. The first lead screw 42 controls the movable scraping plate 41 to move leftward along the bottom of the movable block 3, and the limiting block 44 guides and limits the movement. When the turntable 43 is rotated in the reverse direction, the first lead screw 42 controls the movable scraping plate 41 to move rightward along the bottom of the movable block 3, adjusting the position of the circular through hole 45. The injection molding liquid is poured into the injection molding pipe on the surface of the movable block 3 and enters the chambers inside the movable mold 1 and the fixed mold 2 through the injection molding holes and the circular through hole 45 of the movable block 3. The movable scraping plate 41 cuts off the injection molding liquid. When the injection molding liquid inside the cavities of the movable mold 1 and the fixed mold 2 cools down, no cylindrical silicone blocks will remain on the surface of the silicone product.

[0034] As shown in the Figure 4 and Figure 6 accompanying drawings, a moving mechanism 5 is fixedly installed on the upper surface of the movable block 3 to facilitate the treatment of excess silicone injection molding liquid. The moving mechanism 5 includes a protective shell 51, a linkage plate 52, a second lead screw 53, and a driving block 54. Protective shells 51 are symmetrically and fixedly connected to the upper surface of the movable mold 1. A linkage plate 52 is fixedly connected to the upper surface of the movable block 3, and the linkage plate 52 slides inside the protective shell 51. A second lead screw 53 is rotatably connected to the side of the protective shell 51 away from the movable block 3, and the second lead screw 53 is threadedly connected to the linkage plate 52. A driving block 54 is fixedly connected to the side of the second lead screw 53 away from the protective shell 51.

[0035] Furthermore, the moving mechanism 5 further includes sliders 55. Sliders 55 are fixedly connected to both sides of the linkage plate 52, and the sliders 55 slide inside the protective shell 51.

[0036] In this embodiment, the driving block 54 is rotated to drive the second lead screw 53 to rotate inside the protective shell 51. The second lead screw 53 controls the left - right movement of the linkage plate 52. The linkage plate 52 drives the movable block 3 to adjust its position. The sliders 55 ensure the horizontal movement of the linkage plate 52. After the scraping mechanism 4 cuts off the injection molding liquid, the excess injection molding liquid remains inside the injection molding holes of the movable block 3. After the injection molding liquid inside the cavities of the movable mold 1 and the fixed mold 2 cools down, the moving mechanism 5 adjusts the position of the movable block 3 to facilitate the treatment and recovery of the excess injection molding liquid inside the injection molding holes of the movable block 3.

[0037] As shown in the Figure 2 accompanying drawings, four positioning columns 6 are symmetrically and fixedly connected to the upper surface of the fixed mold 2, and the positioning columns 6 are slidably inserted through the movable mold 1.

[0038] In this embodiment, when the movable mold 1 is moved closer, the positioning columns 6 enter the inside of the movable mold 1, providing rectangular guidance for the mold - closing of the movable mold 1 and the fixed mold 2, and improving the mold - closing speed of the movable mold 1 and the fixed mold 2.

[0039] As shown in the Figure 3 and Figure 8As shown, on the side of the moving die 1 away from the movable block 3, blanking ports 7 are symmetrically arranged.

[0040] In this embodiment, when the movable block 3 moves above the blanking port 7, the excess injection liquid enters the interior of the blanking port 7, facilitating the recovery of the excess injection liquid.

[0041] The above content is a further detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
