[0033] Figure 2 This is a disassembly diagram of a side core-pulling injection mold;

[0034] Figure 3 It is a cross-sectional view of a side core-pulling injection mold;

[0035] Figure 4 for Figure 3 Enlarged view of part A in the middle;

[0036] like Figure 1-4 As shown, a side core-pulling injection mold disclosed in the present invention may include: a mold mechanism, a core-pulling mechanism, a fixing mechanism and other components;

[0037] like Figure 1-4 As shown, the mold mechanism includes a left mold 1, a right mold 25, a column groove 23, and a limiting column 24;

[0038] The right mold 25 is arranged on one side of the left mold 1 and has the same structure as the left mold 1. The four column grooves 23 are rectangularly opened on the side of the left mold 1. The four limiting columns 24 are respectively arranged in the four column grooves 23 and the ends are fixedly connected to the right mold 25.

[0039] Insert the four limiting columns 24 of the right mold 25 into the corresponding column grooves 23 of the left mold 1 so that the left mold 1 and the right mold 25 form a complete mold, so that the mold can be used for injection molding;

[0040] like Figure 1-4 As shown, it includes an electric push rod 2, a mounting plate 3, a mold core 4, a fixing ring 5, a round rod 6, a mounting ring 7, a sealing gasket 8, a first spring 9, and a limit plate 10;

[0041] The electric push rod 2 is installed on the side of the left mold 1, the mounting plate 3 is installed on the end of the electric push rod 2, the mold core 4 is installed on the side of the mounting plate 3 and extends into the left mold 1, the fixing ring 5 is installed on the side of the mold core 4 located outside the left mold 1, the surface of the fixing ring 5 is provided with two sliding holes, the two round rods 6 are respectively slidably arranged in the two sliding holes, the mounting ring 7 is installed on the ends of the two round rods 6, the sealing gasket 8 is installed on the side of the mounting ring 7, each of the first springs 9 is respectively sleeved on the surface of the corresponding round rod 6, and each of the limit plates 10 is installed at the other end of the corresponding round rod 6;

[0042] When inserting the core, the electric push rod 2 shortens and drives the core 4 to be inserted into the combined mold through the mounting plate 3. When the sealing gasket 8 contacts the left mold 1, the sealing gasket 8 and the mounting ring 7 stop moving due to the limit of the left mold 1, and the core 4 that continues to move will compress the first spring 9 through the fixing ring 5. The rebound force of the compressed first spring 9 acts on the sealing gasket 8 to squeeze the sealing gasket 8. The sealing gasket 8 can be used to seal the gap between the core 4 and the left mold 1 and the right mold 25 to prevent liquid from flowing out during the injection molding process. When pulling the core, the electric push rod 2 extends to drive the core 4 to be pulled out of the mold, and at the same time, the first spring 9 extends to drive the sealing gasket 8 to restore its position;

[0043] Figure 5 A cross-sectional view of the fixing mechanism of a side core-pulling injection mold

[0044] like Figure 1-2 and Figure 5 As shown, the fixing mechanism includes a fixing seat 11, a card slot 12, a cavity 13, a limit block 14, a second spring 15, a plug-in 16, a strip groove 17, a shift block 18, a side plate 19, a card member 20, and a slot 21;

[0045] The two fixing seats 11 are respectively mounted on the upper and lower surfaces of the left mold 1, each group of two card slots 12 are respectively opened on the sides of the two fixing seats 11, each cavity 13 is opened inside the corresponding fixing seat 11 and is on one side of the card slot 12, each limiting block 14 is arranged inside the corresponding cavity 13, each second spring 15 is arranged in the corresponding cavity 13 and is on one side of the limiting block 14, each plug-in 16 is installed at the center of the other side of the corresponding limiting block 14 and extends into the corresponding card slot 12, each strip groove 17 is opened on the upper surface of the corresponding fixing seat 11 and communicates with the corresponding cavity 13, each shift block 18 is installed on the surface of the corresponding limiting block 14 and extends to the outside of the fixing seat 11 through the strip groove 17, the two side plates 19 are installed on the upper and lower surfaces of the two right molds 25 and are on one side of the two fixing seats 11, each card 20 is respectively arranged in the corresponding card slot 12 and the side is fixedly connected to the side plate 19, and each slot 21 is opened on the side of the corresponding card 20;

[0046] When assembling the molds, simultaneously move the upper and lower groups of shift blocks 18 so that the two shift blocks 18 of each group are close to each other. Each moving shift block 18 drives the limit block 14 to move, and while compressing the second spring 15, it also drives the plug-in 16 to move out of the card slot 12 and into the cavity 13. Then, the four clips 20 of the right mold 25 are inserted into the corresponding four card slots 12 to combine the right mold 25 with the left mold 1 until the slot 21 of each clip 20 is aligned with the plug-in 16. Then, release the four shift blocks 18 to allow each second spring 15 to rebound and drive the limit block 14 to restore its position, thereby driving the plug-in 16 to be inserted into the aligned slot 21, thereby combining the right mold 25 with the left mold 1. When disassembling the left mold 1 and the right mold 25, it is only necessary to move each group of chain shift blocks 18 to make them close to each other. Through the above operation, each plug-in 16 is moved out of the slot 21, and the fixation of the clip 20 can be released. Then, the right mold 25 and the left mold 1 can be disassembled.
