After the position is reached, the injection molding machine will start to inject glue for production; after the mold injection is completed, the mold is opened, and the panel is pulled open to drive the runner and the glue inlet to separate from the front mold core 1; the mold is continued to be opened to separate the AB plate, and at the same time, the inclined guide column 2 drives the No. 1 slider 4 and the No. 2 slider 5 and the slider ejector pin 3 to move outward to separate from the buckle position; the ejector rod Push the ejector plate 11 to drive the dome pin 7 to eject the product from the rear mold core 6. The dome pin 7 penetrates the positioning block 18 and pushes the slider pin 3 up and out of the diving port from the top; take out the side glue inlet of the product; manually cut off the side glue inlet; by making a slider in the left and right directions of the rear mold, the fine water inlet is turned from the middle of the slider into the water to inject glue (with a spring pin to cooperate with the demolding), first ensure that the mold strength is guaranteed, the processing volume is simplified, the injection molding production is smooth and the cost is saved, and the mold processing cycle is controlled within the specified time.

[0025] See also Figure 1 As shown, a top cover 8 is fixedly connected to the top of the front mold core 1 , and a glue injection port communicating with the molding cavity 13 is installed on the top of the top cover 8 .

[0026] It should be noted that the glue injection port of the utility model is a place for injecting plastic material. The glue injection port is communicated with the molding cavity 13, so that the glue injection port is connected with the molding cavity, so that the plastic material can flow into the molding cavity to form the final product shape.

[0027] See also Figure 3 ,4 As shown, the four bottom corners of the front mold core 1 are fixedly connected with guide pillars 14 , and the four top corners of the rear mold core 6 are provided with positioning holes 15 corresponding to the guide pillars 14 .

[0028] It should be noted that the guide pins and positioning holes of the utility model can ensure that the mold is correctly aligned when closed, so that the various components of the mold can be accurately positioned, thereby ensuring the accuracy and consistency of the molded parts; the fixed connection of the guide pins and the opening of the positioning holes can enhance the stability of the mold, reduce vibration and deformation under high pressure, thereby extending the service life of the mold.

[0029] See also Figure 2 , 4 As shown in FIGS. 5 and 6 , the tops of the No. 1 slider 4 and the No. 2 slider 5 are both provided with inclined holes for use with the inclined guide pillars 2 .

[0030] It should be noted that the inclined guide pin of the utility model can transmit motion by cooperating with the inclined hole on the top of the slider, thereby driving the slider to make linear motion in the mold. The relative motion of the first slider 4 and the second slider 5 can be realized to realize the opening and closing of the mold, thereby ensuring the accuracy and stability of the mold during operation.

[0031] See also Figure 4 As shown, the bottom of the No. 1 slider 4 and the No. 2 slider 5 are embedded with a positioning block 18, the positioning block 18 is provided with a through hole corresponding to the position of the slider ejector pin 3, the slider ejector pin 3 has a T-shaped structure, and the outer side of the slider ejector pin 3 is provided with a No. 2 return spring 17.

[0032] It should be noted that the slider ejector 3 of the utility model is an inverted T-shaped structure. The slider ejector 3 slides inside the No. 1 slider 4 and the No. 2 slider 5. A No. 2 return spring 17 is sleeved on the outside. Under the action of the elastic force and the bottom area being larger than the upper area, the slider ejector 3 is downwardly fitted with the positioning block 18. A through hole is provided in the middle of the positioning block 18. When the No. 1 slider 4 and the No. 2 slider 5 move to the demolding position, the through hole corresponds to the ejector plate 11. The ejector plate 11 penetrates the positioning block 18 to lift the slider ejector 3, thereby realizing ejection from the diving port 19.

[0033] See also Figure 1 , 2 As shown, the bottom of the rear mold core 6 is fixedly connected to a base 9, the middle of the base 9 is fixedly connected to a fixed column 12, the outer side of the fixed column 12 is slidably connected to a top plate 11, a No. 1 return spring 10 is provided on the top of the top plate 11, and a dome needle 7 is fixedly connected to the top of the top plate 11, which extends into the mold core 6 and passes through the top of the rear mold core 6.

[0034] It should be noted that, in the utility model, after the No. 1 slider 4 is separated from the No. 2 slider 5, the push rod pushes the top plate 11 to move upward, and the top plate 11 drives the dome needle 7 to move upward, so that the dome needle 7 penetrates the rear mold core 6 to lift the workpiece upward. When the external force applied to the top plate 11 is withdrawn, under the action of the No. 1 reset spring 10, the top plate 11 drives the dome needle 7 to reset.
