[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] Reference Figure 1-3The utility model provides an embodiment: a vertical molding line insulator accessory mold, including a frame 2, two mounting rails 1 are arranged at the middle end of the inner wall of the frame 2, a plurality of front molds 5 are slidably connected to the inner wall of the front mounting rail 1, and a plurality of rear molds 6 are slidably connected to the inner wall of the rear mounting rail 1, and a cavity is opened on the adjacent side of the front mold 5 and the rear mold 6, and the bottom ends of the left and right sides of the frame 2 are connected to the two mounting rails 1 through screws 3, and the top ends of the left and right sides of the frame 2 are connected to the two mounting rails 1 through slide bars 4, and the right side of the mounting rail 1 is connected to a limiting member 8 by bolts, and the limiting member 8 is used to block the opening on the right side of the mounting rail 1 for installing the mold, and the front mold 5 and the rear mold 6 are limited and fixed, so as to prevent the front mold 5 and the rear mold 6 from detaching from the mounting rail 1; an injection hole 7 is opened on the top side of the rear mold 6, and the injection hole 7 is connected to the cavity; the bottom side of the frame 2 is fixedly connected with a discharge port 16;

[0026] Specifically, the mold cavity is in the shape of a vertical insulator accessory, and the raw material is injected through the injection hole 7 for injection molding, thereby producing a vertical insulator accessory. By disassembling and assembling a plurality of rear molds 6 and front molds 5 on the mounting rail 1 in a sliding manner, molds of different specifications can be easily replaced to carry out production work of different specifications, thereby improving the flexibility of production. At the same time, the parallel tracks on the mounting rail 1 can be used to realize the positioning of the front mold 5 and the rear mold 6, thereby improving the precision of injection molding in the mold.

[0027] Reference Figure 4 and Figure 5 , a slide groove is arranged inside the middle end of the rear side of the rear mold 6, a pushing block 13 is arranged inside the middle end of the slide groove, and a slider 14 is fixedly connected to the left and right sides of the pushing block 13, and a spring piece 15 is arranged on the front side of the slider 14, one end of the spring piece 15 is connected to the front side of the slider 14, and the other end of the spring piece 15 is connected to the slide groove, and the position of the slide groove where the spring piece 15 and the slider 14 slide is relatively short, which is used to limit the pushing block 13 connected to the slider 14 to prevent the pushing block 13 from being displaced excessively and detaching from the rear mold 6. An abutment 12 is arranged on the rear side of the pushing block 13, and the rear side of the abutment 12 is fixedly connected to the driving end of the electric push rod 11;

[0028] Specifically, if it adheres to the rear mold 6, by starting the electric push rod 11, the electric push rod 11 pushes the abutment 12 to move forward, so that the front end of the abutment 12 abuts against the rear side of the pushing block 13, and pushes the pushing block 13, so that the pushing block 13 pushes the finished product in the cavity to make it detach from the cavity, and drives the slider 14 connected to it to slide in the slide groove, and compresses the spring sheet 15. When the push on the pushing block 13 is released, the reset spring sheet 15 will drive the slider 14 connected to the pushing block 13 to reset.

[0029] Reference Figure 2 and Figure 3, the top end of the rear-end mounting rail 1 is fixedly connected to the slide bar 4, the bottom end of the rear-end mounting rail 1 is sleeved on the outer wall of the screw 3, the top end of the front-end mounting rail 1 is slidably connected to the outer wall of the slide bar 4, and the bottom end of the front-end mounting rail 1 is threadedly connected to the outer wall of the screw 3; the two pulleys 10 fixedly connected to the rear ends of the two screws 3 are connected by a belt, the non-driving end of the motor 9 located at the rear side of one of the pulleys 10 is fixedly connected to the rear side of the frame 2 through a fixing frame, and the driving end of the motor 9 is fixedly connected to the rear side of one of the pulleys 10;

[0030] Specifically, the slide bar 4 is used to stabilize the displacement of the front mounting rail 1, so that when the front mounting rail 1 is displaced by the bottom drive, the top end slides on the slide bar 4 to maintain a stable displacement, avoid scratching the finished product during demoulding, and thus ensure the quality of the finished insulator. The motor 9 drives one of the pulleys 10 connected thereto, and then drives the other pulley 10 to rotate through the belt drive, and the two pulleys 10 drive the screw 3 connected thereto to rotate, and the rotating screw 3 drives the front mounting rail 1 installed with the front mold 5 to displace, so that the front mold 5 is separated from the rear mold 6, so that the finished product inside is exposed, and falls on the discharge port 16, and rolls down along the slope of the discharge port 16.

[0031] Working principle: when the injection molding of the mold is completed, the motor 9 is started, and the motor 9 drives one of the pulleys 10 connected thereto, thereby causing the other pulley 10 to rotate through the belt transmission, and the two pulleys 10 drive the screw 3 connected thereto to rotate, and the rotating screw 3 drives the front end mounting rail 1 installed with the front mold 5 to move, thereby causing the front mold 5 to separate from the rear mold 6, exposing the finished product inside, and falling on the discharge port 16, and rolling down along the slope of the discharge port 16. If it adheres to the rear mold 6, by starting the electric push rod 11, the electric push rod 11 pushes the abutment 12 to move forward, so that the front end of the abutment 12 abuts against the rear side of the push block 13, and pushes the push block 13, so that the push block 13 pushes the finished product in the cavity, causing it to separate from the cavity, and drives the slider 14 connected thereto to slide in the slide groove, and compresses the spring 15. When the push on the push block 13 is released, the reset 15 spring will drive the slider 14 connected to the push block 13 to reset.
