[0015] The beneficial effects of the present invention are:

[0016] By setting a control device, when feeding, the rubber material in the barrel comes out from the discharge pipe, falls into the feed funnel, and then enters the empty slot. At this time, the electric telescopic rod is started first to drive the sliding plate to move and insert between the empty slots, and then the motor is started to let the shaft drive the threaded rod to rotate, so that the installation barrel moves, and the piston and the arc plate move at the same time. The piston pushes the rubber material, and is restricted by the sliding plate. The rubber material will not flow back to the upper part of the empty slot. After being pushed, the rubber material enters the installation tube from the through slot, and then falls into the mold slot, completing the glue feeding, thereby achieving the effect of preventing the rubber material from flowing back during glue feeding.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A glue feeding device for a plastic product mold includes a base 1. In order to facilitate the pushing of the glue, a control device is arranged inside the base 1. The control device includes a motor 2, a threaded rod 3, a mounting cylinder 4 and a piston 5. When the motor 2 is started, the rotating shaft drives the threaded rod 3 to rotate inside the mounting cylinder 4. The rotation of the threaded rod 3 causes the mounting cylinder 4 to move horizontally along the surface of the threaded rod 3, and the mounting cylinder 4 drives the piston 5 to move horizontally.

[0023] In order to ensure that the rubber material does not pass through between the piston 5 and the empty groove 11, the motor 2 is fixedly installed inside the base 1, the threaded rod 3 is fixedly connected to the rotating shaft of the motor 2, and the base 1 is provided with an empty groove 11. The piston 5 is slidably inserted in the empty groove 11, and the mounting tube 4 is fixedly installed on the outer surface of the piston 5. When the motor 2 is started, the rotating shaft drives the threaded rod 3 to rotate, and the piston 5 is stuck in the empty groove 11 to push the rubber material. The piston 5 slides tightly in the empty groove 11 to prevent the rubber material from passing between the piston 5 and the empty groove 11.

[0024] In order to ensure that the mounting tube 4 maintains a stable state for horizontal movement, the interior of the mounting tube 4 is threadedly connected to the outer surface of the threaded rod 3, a limiting rod 41 is fixedly installed on the lower surface of the mounting tube 4, a limiting groove 12 is provided inside the base 1, and the outer surface of the limiting rod 41 is slidably connected to the inside of the limiting groove 12. When the threaded rod 3 rotates, the mounting tube 4 will be controlled to move horizontally, and the limiting rod 41 will be stuck in the limiting groove 12 and move, ensuring that the mounting tube 4 will not rotate and maintain a stable state for horizontal movement.

[0025] In order to ensure that the rubber material does not flow back to the upper part of the empty groove 11 when being pushed, an arc plate 51 is fixedly installed on the outer surface of the piston 5, and the outer surface of the arc plate 51 is slidably connected to the inside of the empty groove 11. The arc plate 51 is located above the mounting tube 4, and an electric telescopic rod 13 is fixedly installed inside the base 1. A sliding plate 14 is fixedly installed at the front end of the electric telescopic rod 13. The arc plate 51 moves with the piston 5 and moves along the empty groove 11 to prevent the rubber material from falling to the periphery of the mounting tube 4. When the electric telescopic rod 13 is started, it drives the sliding plate 14 to move horizontally and is inserted between the empty grooves 11 to prevent the rubber material from flowing back to the upper part of the empty groove 11 when being pushed.

[0026] In order to facilitate the addition of the rubber into the mold groove 17, a through groove 15 is opened inside the base 1 at the leftmost end of the empty groove 11, and a mounting tube 16 is fixedly installed on the outer surface of the base 1 at the front end of the through groove 15. A mold groove 17 is opened inside the base 1 below the mounting tube 16. After the rubber is pushed, it enters the mounting tube 16 from the through groove 15 and then falls into the mold groove 17.

[0027] In order to facilitate the rubber material to enter the empty slot 11 from the barrel 110, a feed funnel 18 is fixedly installed on the upper surface of the base 1 at the uppermost end of the empty slot 11, a mounting plate 19 is fixedly installed on the upper surface of the base 1, and a barrel 110 is fixedly installed on the upper surface of the mounting plate 19. A discharge pipe 111 is fixedly connected to the side of the barrel 110. The rubber material in the barrel 110 comes out of the discharge pipe 111, falls into the feed funnel 18, and then enters the empty slot 11.

[0028] By setting a control device, when feeding, the rubber in the barrel 110 comes out from the discharge pipe 111, falls into the feeding funnel 18, and then enters the empty slot 11. At this time, the electric telescopic rod 13 is started first to drive the sliding plate 14 to move and insert between the empty slots 11, and then the motor 2 is started to let the rotating shaft drive the threaded rod 3 to rotate, so that the mounting barrel 4 moves, and drives the piston 5 and the arc plate 51 to move at the same time. The piston 5 pushes the rubber, and is restricted by the sliding plate 14. The rubber will not flow back to the upper part of the empty slot 11. After being pushed, the rubber enters the mounting tube 16 from the through groove 15, and then falls into the mold groove 17, completing the glue feeding, thereby achieving the effect of preventing the rubber from flowing back during glue feeding.

[0029] Working principle: When feeding, the rubber in the barrel 110 comes out from the discharge pipe 111, falls into the feeding funnel 18, and then enters the empty slot 11. At this time, the electric telescopic rod 13 is started first to drive the sliding plate 14 to move and insert between the empty slots 11, and then the motor 2 is started to let the shaft drive the threaded rod 3 to rotate, so that the mounting barrel 4 moves, and drives the piston 5 and the arc plate 51 to move at the same time. The piston 5 pushes the rubber, and is restricted by the sliding plate 14. The rubber will not flow back to the upper part of the empty slot 11. After being pushed, the rubber enters the mounting tube 16 from the through slot 15, and then falls into the mold slot 17 to complete the glue feeding.
