The motor housing is obtained by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping, etc.
[0003] However, in the existing motor molding molds, most of the material liquid is directly added into the casting cavity through the feed port during the casting molding. When the material liquid enters the casting cavity, it collides with the four walls of the casting cavity, causing the material liquid to be entrained with air, which in turn leads to bubbles after the product is processed, affecting the product quality.

[0029] like Figures 1 to 3 As shown, a guide rod 9 is fixedly connected between the base 1 and the top plate 2, and the lifting assembly 4 also includes a cylinder 43 fixedly arranged on the base 1, a connecting pipe 44 fixedly arranged on the injection port 42, and a fixed pipe 45 fixedly arranged on the connecting pipe 44. The lifting plate 41 is slidably arranged on the guide rod 9, and the output shaft of the cylinder 43 is fixedly connected to the lifting plate 41. A through groove 51 is opened on the upper mold 5 and the through groove 51 is connected to the injection port 42. When in use, the cylinder 43 drives the lifting plate 41 and the upper mold 5 to descend and fit with the lower mold 3 to prepare for injection molding. When the product is formed, the cylinder 43 drives the lifting plate 41 and the upper mold 5 to rise and separate from the lower mold 3 to facilitate the removal of the product.
[0030] like Figure 3 and Figure 4As shown, the injection assembly 6 includes a nut 61 rotatably set on the top plate 2, a first injection tube 62 slidably set on the top plate 2, and a second injection tube 63 fixedly connected to the first injection tube 62. The first injection tube 62 is threadedly connected to the nut 61, and the second injection tube 63 is set to a telescopic structure. The outer wall of the second injection tube 63 fits with the inner wall of the fixed tube 45, wherein the initial position of the end of the first injection tube 62 is located in the connecting tube 44, and the nut 61 drives it to rotate in the square through the driving device. The second injection tube 63 is connected to the injection box, and the raw material is injected into the upper mold 5 and the lower mold 3 through the first injection tube 62 and the second injection tube 63. When in use, when the upper mold 3 descends and fits with the lower mold 5, the first injection tube 62 is stretched, so that the first injection tube 63 follows the upper mold 3 to rise and fall.

When the surrounding raw materials are filled, the raw materials flow to the middle to ensure uniform filling, and the conical structure has a guiding effect, which can reduce the probability of contact between the raw materials and the four walls and reduce the generation of bubbles. When the raw material starts to be injected, the driving device drives the nut 61 to rotate in the opposite direction, and the first injection pipe 62 and the second injection pipe 63 gradually rise to ensure that the raw material is fully filled from bottom to top. When the injection is completed and the raw material no longer flows in, the ball 85 is reset under the action of the spring 84 and pushed into the discharge port 81 to prevent the raw material from dripping.

The opening and closing plate 71 is always in an open state under the action of the telescopic rod 86, so that the opening and closing plate 71 is in an open state during the process of the splash cover 82 returning to the connecting tube 44. When the splash cover 82 returns to the connecting tube 44, the opening and closing plate 71 is reset and closed under the action of the torsion spring to prevent the raw material in the splash cover 82 from dripping and affecting the product quality.

[0037] Working process
[0038] The cylinder 43 drives the lifting plate 41 and the upper mold 5 to descend and fit with the lower mold 3, and at the same time drives the first injection tube 62 to stretch, so that the splash shield 82 descends synchronously. Subsequently, the driving device drives the nut 61 to rotate, and drives the second injection tube 63, the first injection tube 62, and the splash shield 82 to move. When the splash shield 82 descends, the opening and closing plate 71 is pushed open by the push rod 72, and the telescopic rod 86 is stretched at the same time. The opening and closing plate 71 is always in an open state under the action of the telescopic rod 86 until the splash shield 82 reaches the bottom position of the lower mold 3. Subsequently, the raw material flows into the second injection tube 63 and the first injection tube 62. Under the action of pressure, the raw material pushes open the ball 85, and the ball 85 is separated from the discharge port 81 under the action of the spring 84. The raw material flows out through the discharge port 81. Under the action of the conical structure of the splash shield 82, the raw material It preferentially flows to the surroundings and corners of the lower mold 3. When the surroundings are filled with raw materials, the raw materials flow to the middle, so that the raw materials are evenly filled, and the probability of the raw materials contacting the four walls can be reduced, and the generation of bubbles can be reduced. When the raw materials begin to flow in, the driving device drives the nut 61 to rotate in the opposite direction, so that the first injection pipe 62 and the second injection pipe 63 gradually rise, so that the raw materials are fully filled from bottom to top; when the injection molding is completed and the raw materials no longer flow in, the ball 85 is reset and pushed into the feed port 81 under the action of the spring 84 to prevent the raw materials from dripping. At the same time, after the splash guard 82 is retracted into the connecting pipe 44, the opening and closing plate 71 is reset and closed under the action of the torsion spring to prevent the splash guard 82 and the raw materials in the second injection pipe 63 from dripping and affecting the product quality. When the product is formed, the cylinder 43 drives the lifting plate 41 and the upper mold 5 to rise and separate from the lower mold 3 to facilitate the removal of the product.
