DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , 2 As shown in , 3, 4, 5, 6, 7, and 8, the utility model provides a technical solution: a mold structure of an intelligent sensing headset, comprising: a front mold core 1 with an inclined guide column 2 fixedly connected to the bottom; a rear mold core 7 is placed at the bottom of the front mold core 1, and a plurality of sliding inserts 4 and a plurality of inclined tops 5 are slidably inserted in the middle of the rear mold core 7, and the sliding inserts 4 and the inclined tops 5 are alternately arranged and combined on the outer side into an arc structure No. 1, which is used to hold the inner ring of the workpiece in place and to vent, and a No. 3 slider 3 and a No. 2 slider 6 are respectively slidably connected on both sides of the rear mold core 7; a No. 1 slider 9 is slidably placed at the end of the rear mold core 7, and the No. 3 slider 3, the No. 2 slider 6 and the inner side of the No. 1 slider 9 form a No. 2 arc structure, and a glue injection cavity is formed between the No. 1 arc structure and the No. 2 arc structure.

[0026] It should be noted that before the mold of the utility model is closed, the dome pin 8 is first reset to the bottom, the inclined ejector 5 is returned to its original position, and then the movable insert 4 is placed in the corresponding position of the rear mold, and then the AB plates are closed, and the No. 3 slider 3, the No. 2 slider 6 and the No. 1 slider 9 are reset synchronously. After reaching the position, the injection molding machine injects glue again, and the molten glue enters the No. 1 arc structure and the No. 2 arc structure through the injection port to form a glue injection cavity; after the mold is injected and cooled, the mold is opened. The first step is to pull the AB plates apart to open the front and rear molds, so that the front mold core 1 is separated from the rear mold core 7, and at the same time, the inclined guide column 2 drives the No. 3 slider 3, the No. 2 slider 6 and the No. 1 slider 9 to move outward and disengage from the buckle position; the second step is to push the lift rod to lift the mold. The lowering plate 14 drives the dome pin 8 to move upward, and the dome pin 8 lifts the movable insert 4 to eject the product from the rear mold core 7; the third step: take out the product and the movable insert; the fourth step: manually remove the movable insert 4 according to the demoulding direction; the fifth step: manually cut off the side glue inlet; by simplifying the deep bone structure of the mold circle buckle position, reducing unnecessary complex parts, and ensuring that the basic structure and function of the mold are not affected, the deep bone structure of the mold circle buckle position is simplified as much as possible, and an inclined top is designed on the inner side of the mold to cooperate with the movable insert. Through the staggered arrangement, the production efficiency and processing accuracy of the mold can be improved without affecting the product structure and appearance, while saving materials and costs.

[0027] See also Figure 2As shown, a top cover 11 is fixedly connected to the top of the front mold core 1, positioning holes are opened at the four corners of the bottom of the front mold core 1, and positioning columns 15 used in conjunction with the positioning holes are fixedly connected to the corresponding four corners above the rear mold core 7.

[0028] It should be noted that the cooperation of the positioning holes and the positioning columns of the utility model can realize the precise positioning of the front mold core 1 and the rear mold core 7, ensuring the correct alignment of the various components when the mold is closed, thereby ensuring the accuracy and consistency of the molded parts; the front and rear mold core components of the mold can be quickly and accurately disassembled and installed, thereby improving production efficiency.

[0029] See also Figure 4 , 5 As shown in FIGS. 6 and 7 , the inclined guide column 2 is located at positions corresponding to the third slider 3 , the second slider 6 and the first slider 9 , and the tops of the third slider 3 , the second slider 6 and the first slider 9 are all provided with inclined holes that cooperate with the inclined guide column 2 .

[0030] It should be noted that, the utility model slider No. 3 3, slider No. 2 6 and slider No. 1 9 are used for removing the appearance buckle and venting, and the inclined guide column 2 can be used as a guide element for slider No. 3 3, slider No. 2 6 and slider No. 1 9, so that the slider can move along an oblique path during the movement, and the inclined hole on the top of the slider provides a space for cooperating with the oblique guide column 2 to ensure that the slider can cooperate well with the oblique guide column 2 during the movement to achieve accurate position control.

[0031] See also Figure 2 , 4 As shown in Figures 5, 6 and 7, a positioning hole 10 is provided in the middle of the rear mold core 7, and rectangular blocks matching the positioning hole 10 are provided at the bottom of the sliding insert 4 and the inclined top 5, and a dome needle 8 is slidably connected to the middle of the rear mold core 7 and at the position corresponding to the positioning hole 10.

[0032] It should be noted that the positioning hole 10 and the rectangular block of the utility model can ensure the accurate alignment between the rear mold core 7, the sliding insert 4 and the inclined top 5. The inclined top cooperates with the movable insert to form an arc structure by staggered arrangement, thereby forming a full circle of buckle deep bone structure, thereby ensuring the position relationship and stability of each component of the mold during operation. The dome pin 8 is slidably connected to the position of the sliding insert 4 corresponding to the middle part of the rear mold core 7, and the movable insert 4 is lifted up by the dome pin 8 to eject the product from the rear mold 7.

[0033] See also Figure 1 , 2 As shown, the bottom of the rear mold core 7 is fixedly connected to a base 12, the middle of the base 12 is slidably connected to a lifting plate 14, the top of the lifting plate 14 is provided with a return spring 13, and the top of the lifting plate 14 is fixedly connected to the dome needle 8.

[0034] It should be noted that the base 12 of the utility model serves as the bottom connecting component of the rear mold core 7. It ensures the stability of the bottom of the mold through a fixed connection, so that the mold can maintain a stable structure during operation. The lifting plate 14 slides with the base 12, and the lifting plate 14 is pushed upward by the ejector rod. The lifting plate 14 drives the dome needle 8 to move upward, and the dome needle 8 drives the sliding insert 4 to move upward, thereby ejecting the product. When no external force is applied to the lifting plate 14, the lifting plate 14 is reset under the action of the reset spring 13, thereby driving the dome needle 8 to reset through the lifting plate 14.
