[0027] In addition, by controlling the heat-conducting fluids in the fixed mold heat-conducting runner and the moving mold heat-conducting runner at different temperatures respectively, not only can the fixed mold core and the moving mold core be controlled at different temperatures to improve the molding efficiency of the product, but also the temperature of the water temperature control machine is higher, which can reduce the insert line, ejector pin line and lifter line on the surface of the product after molding.

[0028] In addition, the fixed mold heat-conducting runner and the moving mold heat-conducting runner in this embodiment not only have a reasonable layout, but also can effectively increase the mold temperature, improve the fluidity during the plastic molding process, and reduce the insert line, ejector pin line and lifter line generated on the product surface.

At the same time, the thimble lines will also only appear on the side surfaces of the side ribs 12 away from the top plate 11, and no insert lines or thimble lines will appear on the bottom side of the transparent top plate, thereby avoiding seeing the insert lines and thimble lines formed on the bottom side from the top side of the top plate, and effectively improving the aesthetics, surface finish of the transparent product and the quality of the plastic product.

[0041] As Figures 2-3As shown, the moving mold unit includes a moving mold base plate 22 and a mold leg 23 disposed above the moving mold base plate 22.

Corresponding to the four moving mold inserts 4, the fixed mold core 31 is respectively provided with forming grooves. The four forming grooves respectively form upper cavities 311 with the corresponding moving mold inserts 4. The upper cavities 311 communicate with the lower cavities 212 of the corresponding moving mold inserts 4 to form a cavity for molding the switch rocker plate 1. Of course, the injection mold can also be provided with only one or two or more moving mold inserts 4.

[0043] Furthermore, as Figure 5 shown, the moving mold insert 4 is provided with an insert boss 41 protruding towards the forming groove wall. The forming bottom surface 403 is provided on the insert boss 41. The ejector pin hole on the forming bottom surface 403 passes through the insert boss 41.

Specifically, the forming top surface 401 is rectangular. Four forming side surfaces 402 are provided around the forming top surface 401. The four forming side surfaces 402 are respectively connected to the four side edges of the forming top surface 401.

[0045] As Figures 3-5 shown, the movable mold assembly is provided with a lower thimble plate 51 connected to the thimble seat of the thimble 52. The lower thimble plate 51 is used to drive the thimble 52 to move during mold opening, so that the thimble 52 pushes the product away from the lower cavity 212. The thimble 52 is provided with a thimble seat and a thimble head arranged on the thimble seat. The thimble head is used to pass through the thimble hole. The thimble hole and the forming bottom surface 403 form the side of the lower cavity 212 away from the upper cavity 311. The cross-section of the thimble head is rectangular, and the width of the thimble head is less than or equal to the distance between the forming side surface 402 and the forming groove wall, so that the two thimble lines along the thickness direction of the side rib 12 can respectively coincide with the two side edges of the side rib 12, making the thimble lines more difficult to observe. Of course, the width of the thimble head can also be less than the distance between the forming side surface 402 and the forming groove wall, so that the thimble lines are located near the side edges of the side rib 12, or the thimble lines can be easily observed from the top side.

[0046] As Figure 1 shown, the side of the lower cavity 212 away from the upper cavity 311 is provided with a lower sub-groove 404 for forming the submarine gate 18. The lower sub-groove 404 is communicated with the upper cavity 311. The lower sub-groove 404 is used to connect the submarine gate 61, which can not only realize submarine gating, but also avoid manual shearing, thereby reducing the labor cost.

[0047] Specifically, the movable mold core 21 and the fixed mold core 31 are respectively provided with opposite glue inlet grooves 60 Figures 7-8, the glue inlet grooves 60 of the moving mold core 21 and the fixed mold core 31 are used to form a submarine runner in combination.

The submarine runner includes two U-shaped submarine branches 62 oppositely arranged on both sides of the main runner 90, and a submarine main channel 63 respectively communicating between the two submarine branches 62 and the main runner 90. The openings of the two submarine branches 62 are oppositely arranged. The two submarine branches 62 are respectively arranged between two cavities. The ends of the two submarine branches 62 far from the submarine main channel 63 are respectively communicated with the submarine gate 61. When injecting glue, it first passes through the main runner 90 and is divided into two submarine channels, then divided into the two ends of the two submarine branches 62, and finally enters the cavity through the submarine gate 61. Preferably, the cross-sectional size of the connection position between the submarine gate 61 and the undercut groove 404 is 0.8mm×1.9mm, and the angle of the submarine gate 61 is 40 degrees. Of course, the cross-sectional size and angle of the submarine gate 61 can also be adjusted according to the use environment, which all belong to the protection scope of the present invention.

By arranging the lifter 72 outside the moving mold insert 4, it is not necessary to arrange the lifter 72 inside the moving mold insert 4, and no insert line will be generated on the inner surface of the ejector plate 11, improving the aesthetic appearance of the product.

[0049] As Figure 2 , 4As shown in FIG. -5, the moving die insert 4 is provided with a core-pulling device on the side opposite to the lifter 72. The core-pulling device and the lifter 72 respectively form through holes 17 on two baffles 16. The core-pulling device includes a slider 81 and a guide rod 83 for driving the slider 81 to move. The guide rod 83 is connected to the fixed template 33. When the mold is opened, the fixed template 33 drives the slider 81 away from the cavity through the guide rod 83. A first slider insert 84 is provided on the slider 81, and a second slider insert 85 is provided in the first slider insert 84. The first slider insert 84 is provided with a core-pulling surface 86 opposite to the molding side surface 402. A slider groove 87 is provided in the middle of the core-pulling surface 86.
