The middle of the main body is hollowed out, a rib 603 is arranged on the upper end face of the main body, and a through hole 602 communicating with the inside of the cylinder 601 is opened on the inner side face of the cylinder.

[0035] Reference Figure 2-4 , Figure 7As shown, the utility model discloses a new type of side slider forming mold, including a panel 10, an upper movable mold 20, a lower fixed mold 30, an ejector plate 40 and a bottom plate 50 from top to bottom, an upper mold core 21 is embedded at the bottom of the upper movable mold 20, and a plurality of inclined guide pillars are arranged around the upper mold core 21 of the upper movable mold 20, two lower mold cores 31 are arranged on the lower fixed mold, side forming blocks 314 are arranged on both sides of the lower mold core 31 along the length direction of the lower fixed mold, and a side slider 315 is arranged at one end of the lower fixed mold along the length direction of the lower mold core 31. Specifically, the inclined guide pillars include first inclined guide pillars 212 along both sides of the upper mold core 21 and a plurality of inclined guide pillars 214 along the lower mold core 31. The second inclined guide column 213 at both ends of the upper mold core 21, the first inclined guide column 212 can slide through the side molding block 314, and the second inclined guide column 213 can slide through the side slider 315. When the mold is closed, the first inclined guide column 212 drives the molding blocks 314 on both sides to approach the lower mold core 31, and the second inclined guide column 213 drives the side slider 315 to approach the lower mold core 31. The molding blocks 314 on both sides, the lower mold core 31 and the upper mold core 21 are used to form the main body of the shell 60 and the side cylinder 601, and the sliders 315 on both sides are used to form the through hole 602 on the inner side of the shell 60 that is connected to the inside of the cylinder 601.

[0036] Reference Figure 3-6 As shown, the side slider 315 includes an upper molding block 3153, a connecting rod 3152 and a side guide block 3151. The upper molding block 3153 and the side guide block 3151 are respectively arranged at both ends of the connecting rod 3152 and in opposite directions. The first core 311 and the second core 313 are arranged on the lower mold core 31. The first core 311 has an L-shaped guide hole 3111. The connecting rod 3152 can be slidably placed in the vertical part of the guide hole 3111. The side guide block 3151 can be slidably placed in the horizontal part of the guide hole 3111 and extend out of the lower mold core 31. The inclined guide column can slide through the side guide block 3151. The upper molding block 3153 can slide out of the guide hole 3111 and abut against the side of the second core 313. Specifically, the first core 311 is hollowed out inside, and the upper end of the first core 311 includes a detachable cover plate 312, which facilitates the installation of the side guide block 3151. During mold closing and injection molding, the second inclined guide column 213 pushes the side guide block 3151 to push the connecting rod 3152 in the guide hole 3111 toward one side of the second core 313, and pushes the upper molding block 3153 to contact the side of the second core 313, which is used to mold the through hole 602 inside the shell 60 that connects to the cylinder 601. Furthermore, the cover plate 312 is further provided with three molding grooves 3122, which are used to mold the ribs 603 on the upper end surface of the shell 60. When the mold is opened, the first inclined guide column 212 drives the two side forming blocks 314 to leave the lower mold core 31, and at the same time the second inclined guide column 213 drives the side guide block 3151 of the side slider 315 to leave the first core 311, and the side guide block 3151 drives the upper forming block 3153 to leave the side of the second core 313 through the connecting rod 3152.

[0037] Reference Figure 3-6 As shown, the upper mold core 21 is provided with a wedge block 211, the cover plate 312 is provided with a square hole 3121, and the corresponding upper molding block 3153 is provided with a notch near the connecting rod 3152. When the mold is closed, the upper mold core 21 and the lower mold core 31 are closed, and the wedge block 211 can be inserted into the notch from the square hole 3121 of the cover plate 312, ensuring that the upper molding block 3153 can completely contact the side of the second core 313, avoiding the formation of burrs on the inner side of the through hole 602.

[0038] Reference Figure 3-6 As shown, a pre-tightening mechanism is arranged on the side of the lower fixed mold 30, and the pre-tightening mechanism includes a bracket, on which a pre-tightening spring 301 and a push rod 302 are installed, and the pre-tightening spring 301 pushes the push rod 302 to support the side slider 315. Specifically, during mold closing and injection molding, the pre-tightening spring 301 pushes the upper molding block 3153 of the side slider 315 to contact the second core 313, further playing an auxiliary role in pushing the side slider 315 to slide into place.

[0039] Reference Figure 3-6 As shown, a plurality of ejector pins 402 and ejector rods 401 are provided on the ejector plate 40. The ejector pin 402 can slide through the first core 311, and the ejector rod 401 can slide through the second core 313. Specifically, when the mold is opened, the ejector plate 40 pushes the ejector pin 402 upward to push the main body on the first core 311 out, and the ejector rod 401 pushes the cylinder 601 on the second core 313 out.
