Description

Technical Field

[0001] The utility model relates to the field of mold processing, and specifically relates to a device for controlling the uniform injection of rubber molds. Background Technique

[0002] During the injection process, rubber materials are usually injected into the mold in a liquid or semi-liquid form. The design and manufacture of the mold are very crucial. It needs to be precisely processed according to the shape and size of the required product to ensure that the rubber material can evenly fill the mold cavity during the injection process, so as to produce various rubber products, such as rubber seals, rubber pipes, rubber tires, etc., and form qualified products after curing.

[0003] Currently, during the injection process, usually, operators directly pour the raw materials into the inside of the processing mold. At this time, if the injection speed is uneven, it will cause the rubber to be unevenly distributed in the mold, thereby affecting the quality and performance of the product, and further causing problems such as bubbles, lack of glue, and deformation in the product. In addition, uneven feeding will cause inconsistent mold filling times, thus affecting production efficiency; therefore, a device for controlling the uniform injection of rubber molds is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the existing technology and avoid the problem of reduced quality of subsequent products caused by uneven injection, the utility model proposes a device for controlling the uniform injection of rubber molds.

The rotating rod drives the connecting ring and the stirring rod to rotate. At this time, the stirring rod stirs the passing materials, making the materials more uniform, while the convex block ensures that the support device does not separate from the support sleeve.

[0009] Preferably, the collection assembly includes two communicating pipes fixedly installed on the left and right sides of the top of the cylinder body. The top of the communicating pipe is fixedly installed with a telescopic rod. A plug rod is inserted into the telescopic rod. The top of the telescopic rod is fixedly connected to a hollow plate.

[0025] Referring to Figure 2 - Figure 3The stirring assembly 3 includes a support rod 31 that is clamped in the cylinder 1. The end of the support rod 31 that is away from the inner wall of the cylinder 1 is fixedly connected to a support sleeve 32. The support sleeve 32 is rotatably connected to a rotating rod 33. The surface of the top of the rotating rod 33 is fixedly connected to a spiral blade 34. The top of the rotating rod 33 extends to the inside of the injection barrel 2. The spiral blade 34 is located in the inside of the injection barrel 2. When the material is injected into the inside of the injection barrel 2, the raw material will pass through the spiral blade 34 and then push the rotating rod 33 to rotate. The surface of the rotating rod 33 is located on the upper and lower sides of the support sleeve 32 and is rotatably connected to a connecting ring 35. The surface of the connecting ring 35 is fixedly connected to a stirring rod 36. The end of the connecting ring 35 close to the support sleeve 32 is fixedly connected to The support device 37 and the support sleeve 32 are fixedly connected with protrusions 38 on the upper and lower sides, and the stirring rod 36 extends obliquely away from the connecting ring 35 to the center away from the support sleeve 32. The support device 37 is composed of a vertical rod and a connecting plate. The connecting plate is fixedly connected to the end face of the connecting ring 35, and the connecting plate is fixedly connected to the end of the vertical rod away from the connecting ring 35. The upper and lower sides of the support sleeve 32 are provided with sliding grooves that are adapted to be slidably connected with the connecting plate. The protrusions 38 and the cross plates are adapted to contact, and the rotating rod 33 will drive the connecting ring 35 and the stirring rod 36 to rotate. At this time, the stirring rod 36 stirs the passing material to make the material more uniform, and the protrusions 38 ensure that the support device 37 will not separate from the support sleeve 32.

[0026] Reference Figure 4 - Figure 5 The collecting assembly 4 includes two connecting tubes 41 fixedly mounted on the left and right sides of the top of the cylinder 1, a telescopic rod 42 is fixedly mounted on the top of the connecting tube 41, a plug rod 43 is inserted on the surface of the telescopic rod 42, a hollow plate 44 is fixedly connected to the top of the telescopic rod 42, a winding rope 45 is wound around the inside of the hollow plate 44, a screw 46 is threadedly connected to the surface of the hollow plate 44, a collecting bag 47 is sleeved on the surface of the top of the connecting tube 41, the connecting tube 41 is connected to the inside of the cylinder 1, the winding rope 45 and the collecting bag 47 are in matching contact, the winding rope 45 can close the bottom of the collecting bag 47, a groove matching the collecting bag 47 is provided on the surface of the connecting tube 41, the screw 46 extends to the inside of the hollow plate 44, the winding rope 45 is wound around the surface of the screw 46, the screw 46 can be rotated to tighten the winding rope 45, and the winding rope 45 closes the bottom of the collecting bag 47.

[0027] Working principle: After the operator injects the raw materials into the interior of the injection barrel 2, the raw materials pass through the spiral blade 34 inside the injection barrel 2 and move downward. Therefore, the spiral blade 34 is pushed by the raw materials to drive the rotating rod 33 to rotate inside the support sleeve 32. At the same time, the rotating rod 33 will drive the connecting ring 35 to rotate accordingly. The connecting ring 35 will drive the stirring rod 36 to rotate inside the cylinder body 1. At this time, the stirring rod 36 stirs the raw materials that have moved into the interior of the cylinder body 1. Therefore, the stirring rod 36 stirs the raw materials inside the cylinder body 1, making the raw materials evenly distributed. During the rotation of the connecting ring 35, the support device 37 fixedly connected to the connecting ring 35 always slides inside the support sleeve 32, so that the connecting ring 35 always rotates stably;

[0028] Before processing the rubber raw materials, the operator sleeved the collection bag 47 on the surface of the connecting pipe 41, and then rotated the screw rod 46 to wind the winding rope 45. At this time, the winding rope 45 was tightened to tightly sleeve the collection bag 47 on the surface of the connecting pipe 41. Then, during the process of processing the rubber raw materials, dust and hydrogen sulfide waste gas will be generated. At this time, the waste gas will move upward and enter the interior of the collection bag 47 through the connecting pipe 41. When the injection processing is completed, the operator stretches the telescopic rod 42 and drives the hollow plate 44 to move upward. At this time, the winding rope 45 inside the hollow plate 44 will drive the collection bag 47 to move upward. When the winding rope 45 disengages from the connecting pipe 41, at this time, the operator can rotate the screw rod 46 and continue to wind the winding rope 45. Therefore, the winding rope 45 will tighten the collection bag 47. At this time, the bottom of the collection bag 47 disengages from the connecting pipe 41 and is sealed. Then, the operator can remove the collection bag 47 and process the waste gas inside.
