The top seat then moves the upper mold closer to the lower mold, causing them to fit together and allowing the rubber material to solidify between them. By controlling the reverse rotation of the motor, the threaded rod rotates in the opposite direction, moving the top seat and upper mold upwards. Simultaneously, the threaded rod drives a reciprocating screw, which, via a lifting plate, causes a lifting block to reciprocate between limit bars.

This ensures that the cooling airflow evenly covers the surface of the lower mold, resulting in uniform cooling of the rubber plug product inside and improving the cooling effect.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example: Please refer to Figures 1-4 This utility model provides a technical solution: a medical rubber stopper production mold with rapid cooling, including a base 1, a top seat 11 arranged directly above the base 1, a lower mold 2 fixedly connected to the top of the base 1, an upper mold 21 fixedly connected to the bottom of the top seat 11, a pair of fixing rods 22 fixedly connected to both sides of the base 1, a triangular plate 23 fixedly connected to the top of each pair of fixing rods 22, a threaded rod 24 rotatably connected to the bottom of each triangular plate 23, the top seat 11 threadedly sleeved on the outer side wall of the two threaded rods 24, the top seat 11 slidably sleeved on the outer side wall of the two pairs of fixing rods 22, two pairs of fixing blocks 25 fixedly connected to the top of the base 1, a blower 26 rotatably connected between each pair of fixing blocks 25, a blower 27 opened on the side of the blower 26 near the lower mold 2, a rotating shaft 28 rotatably connected to the outer side of each pair of fixing blocks 25, one end of the rotating shaft 28 penetrating through the side wall of the fixing block 25 and fixedly connected to the blower 26.

[0021] Connecting rods 3 are fixedly connected to the outer walls of both pairs of rotating shafts 28. Pull rods 31 are rotatably connected to the side of each pair of connecting rods 3 that is close to each other. By setting pull rods 31, during the up-and-down swinging process of pull rods 31, the two pairs of pull rods 31 drive the two pairs of rotating shafts 28 to rotate in the forward and reverse directions through the two pairs of connecting rods 3. The two pairs of rotating shafts 28 drive the two blowers 26 to rotate in the forward and reverse directions on both sides of the lower mold 2, thereby changing the blowing angle of the blower 27 to the lower mold 2.

[0022] The bottom end of each threaded rod 24 is fixedly connected to a reciprocating screw 4, and the bottom end of each reciprocating screw 4 is rotatably connected to the base 1. Each reciprocating screw 4 has a lifting plate 41 threadedly sleeved on its outer side wall. Both ends of the lifting plate 41 are fixedly connected to lifting blocks 42. Each lifting block 42 has a curved groove 43 on its outer side wall. By setting the reciprocating screw 4, during the rotation of the reciprocating screw 4, the two reciprocating screws 4 drive the two pairs of lifting blocks 42 to move up and down through the lifting plates 41 on their outer sides. The two pairs of lifting blocks 42 drive the curved grooves 43 on their outer sides to move up and down. Under the limiting action of the curved grooves 43, the two pairs of lifting blocks 42 drive the two pairs of pull rods 31 to swing up and down through the curved grooves 43.

[0023] Both the threaded rod 24 and the reciprocating screw 4 are fixedly connected to a retaining ring 5 at their closest ends. By setting the retaining ring 5, the lifting plate 41 and the top seat 11 are limited, preventing the lifting plate 41 from separating from the reciprocating screw 4 and the top seat 11 from the threaded rod 24, thereby improving the overall stability of the equipment.

[0024] Four sets of limiting strips 6 are fixedly connected to the top of the base 1. The lifting blocks 42 are all slidably connected between the same set of limiting strips 6. By setting the limiting strips 6, the lifting blocks 42 are limited, so that the lifting blocks 42 move in the vertical direction, thereby improving the driving effect of the reciprocating screw 4 on the lifting plate 41 and the lifting blocks 42.

[0025] Motors 7 are fixedly connected to the top of each triangle plate 23. The output ends of motors 7 pass through the side wall of triangle plate 23 and are fixedly connected to threaded rods 24. By controlling the forward and reverse rotation of motors 7, motors 7 drive threaded rods 24 to rotate forward and reverse at the bottom of triangle plate 23 through their output ends, thereby causing threaded rods 24 to drive the top seat 11 on its outer side to move downward and upward along fixed rods 22.

[0026] The bottom of the base 1 is fixedly connected with four support legs 8. By setting the support legs 8, the support legs 8 can provide stable support for the lower mold 2 and the upper mold 21, reduce the shaking and deformation of the rubber stopper product during processing, and thus improve the processing accuracy and product quality of the rubber stopper.

[0027] Working principle: By activating the motor 7 at the top of the triangular plate 23, both motors 7 rotate in the forward direction. The output of the two motors 7 drives the two threaded rods 24 to rotate below the triangular plate 23. The two threaded rods 24 drive the top seat 11 to slide downwards along the side walls of the two pairs of fixed rods 22. The top seat 11 drives the upper mold 21 at its bottom to move closer to the lower mold 2, causing the upper mold 21 and lower mold 2 to fit together, thus allowing the rubber material to solidify between the upper mold 21 and lower mold 2. By controlling the two motors 7 to rotate in the reverse direction, the two motors 7 drive the two threaded rods 24 to rotate in the reverse direction. The two threaded rods 24 drive the top seat 11 and the upper mold 21 to move upwards along the two pairs of fixed rods 22. Simultaneously, the two threaded rods 24 drive the reciprocating screw 4 at its bottom to rotate, within the four sets of limiting strips 6. Under the limiting action, the two reciprocating screws 4 drive the two pairs of lifting blocks 42 to move up and down between the same set of limiting bars 6 through the lifting plate 41 on their outer side. The two pairs of lifting blocks 42 drive the curved groove 43 on their outer side to move up and down. Under the limiting action of the curved groove 43, the two pairs of lifting blocks 42 drive the two pairs of pull rods 31 to swing up and down through the curved groove 43. The two pairs of pull rods 31 drive the two pairs of rotating shafts 28 to rotate in the forward and reverse directions through the two pairs of connecting rods 3. The two pairs of rotating shafts 28 drive the two blowers 26 to rotate in the forward and reverse directions on both sides of the lower mold 2, thereby changing the blowing angle of the blower 27 on the lower mold 2, so that the cooling airflow evenly covers the surface of the lower mold 2, thereby making the rubber plug product in the lower mold 2 cool evenly and improving the cooling effect on the rubber plug product.
