Description

Technical Field

[0001] The utility model relates to the technical field of demoulding structures, in particular to a demoulding structure for an injection mould for rubber product forming. Background Technique

[0002] In the prior art, the patent with the publication number of CN220923202U discloses a demoulding structure for an injection mould for rubber product forming. Technical problem: The flash generated during the injection moulding process of rubber products will generate a shearing force between the rubber finished product and the top mould, which is likely to cause the edge of the rubber finished product to crack. Technical solution: A demoulding structure for an injection mould for rubber product forming, including a mould assembly, a transmission assembly, a sliding assembly, a cutting assembly, a pressing assembly, and a purging assembly. The utility model, through the slidable cutting assembly arranged on the mould assembly, in cooperation with the original top-pushing demoulding mechanism of the mould, can cut off the flash at the end edge of the rubber finished product before demoulding, avoiding the shearing force between the flash adhered to the mould and the finished product during the top-pushing process, resulting in the cracking of the edge of the rubber finished product, and ensuring the qualified rate of the rubber finished product. The purging assembly arranged on the cutting assembly can cool and blow and purge the flash while cutting it.

[0003] During the actual use process of the above-mentioned equipment, although the cutting assembly and the purging assembly can be used to trim the edge of the mould, and then the top-end assembly is used to push the rubber product out of the mould, after the rubber product is pushed out of the mould, it still requires the staff to manually take out the rubber product for storage. Moreover, the rubber product will remain at a certain temperature during the injection moulding process, which may cause the situation that the staff is scalded by the rubber product.

[0004] Therefore, a demoulding structure for an injection mould for rubber product forming is proposed. Content of the Utility Model

An installation plate 32 is rotatably installed on the two limiting rods 31. A limiting groove 314 is formed on the installation plate 32. The two limiting rods 31 are both rotatably installed in the limiting groove 314. A connecting plate 33 is slidably installed on the installation plate 32. An electric telescopic rod 34 is installed on the connecting plate 33. An air extraction pump 35 is installed on the electric telescopic rod 34. A connecting box 36 is installed on the air extraction pump 35. An air extraction hood 37 is installed on the connecting box 36. The air extraction hood 37 is in contact with the rubber product body 2. Two fixing plates 38 are installed on the installation plate 32. A threaded rod 39 is rotatably installed on the two fixing plates 38. A threaded sleeve 310 is threadedly installed on the threaded rod 39. A cross-shaped slider 312 is installed on the threaded sleeve 310. The cross-shaped slider 312 is installed on the connecting plate 33. A cross-shaped sliding groove 313 is formed on the installation plate 32. The cross-shaped slider 312 is slidably installed on the inner wall of the cross-shaped sliding groove 313. One end of the threaded rod 39 is provided with a first motor 311, and the first motor 311 is installed on the installation plate 32. After the air extraction hood 37 rotates to the upper part of the rubber product body 2, the first motor 311 is used to drive the threaded rod 39 to rotate. The threaded rod 39 drives the threaded sleeve 310 to move. The threaded sleeve 310 drives the electric telescopic rod 34 to move. The electric telescopic rod 34 drives the air extraction hood 37 to move to directly above the rubber product body 2. Then, the electric telescopic rod 34 is used to drive the air extraction pump 35 to move downward. The air extraction pump 35 drives the air extraction hood 37 to contact the rubber product body 2. At this time, the switch on the air extraction pump 35 is turned on. The space where the air extraction hood 37 contacts the rubber product body 2 is pumped into a vacuum state by the air extraction pump 35, so that the air extraction hood 37 and the rubber product body 2 can be closely attached together. Then, the electric telescopic rod 34 is retracted upward, and the electric telescopic rod 34 is used to take out the rubber product body 2 from the mould in the mould assembly 1.

[0024] Embodiment 2: On the basis of Embodiment 1, in order to facilitate moving the taken-out material to the unloading area for unloading, a rotating mechanism is arranged on the support plate 3, which specifically includes a second motor 4. The second motor 4 is installed on the support plate 3, a driving shaft 41 is installed on the second motor 4, the top end of the driving shaft 41 is installed on the mounting plate 32, a retaining plate 42 is installed on the support plate 3, a retaining hole 43 is formed on the retaining plate 42, the driving shaft 41 is rotatably installed in the retaining hole 43.

The driving shaft 41 drives the mounting plate 32 on the limiting rod 31 to rotate, and the mounting plate 32 drives the air extraction hood 37 to rotate, so that the air extraction hood 37 can be conveniently moved to the position above the rubber product body 2 to prepare for taking out the rubber product body 2. After the rubber product body 2 is taken out, the second motor 4 is used to drive the driving shaft 41 to rotate in the reverse direction, so that the rubber product body 2 on the air extraction hood 37 can be conveniently moved to the unloading area for unloading. At the same time, by setting the retaining hole 43 with an angle of 270° on the retaining plate 42, the air extraction hood 37 can be conveniently and accurately moved to the material taking position and the unloading position. The other features are the same as those in Embodiment 1.

[0025] The working principle is as follows: After the rubber product body 2 on the mold assembly 1 is trimmed at the edge of the mold by using the cutting and purging assembly, the switch on the second motor 4 is activated. The second motor 4 drives the drive shaft 41 to rotate in the retaining hole 43 on the retaining plate 42. The drive shaft 41 drives the mounting plate 32 on the limiting rod 31 to rotate, and the mounting plate 32 drives the air extraction hood 37 to rotate. Then, the switch on the first motor 311 is activated. The first motor 311 drives the threaded rod 39 to rotate, and the threaded rod 39 drives the threaded sleeve 310 to move. The threaded sleeve 310 drives the cross-shaped slider 312 to move, the cross-shaped slider 312 drives the connecting plate 33 to move, the connecting plate 33 drives the electric telescopic rod 34 to move, the electric telescopic rod 34 drives the air extraction pump 35 to move, and the air extraction pump 35 drives the air extraction hood 37 on the connecting box 36 to move to directly above the rubber product body 2. Then, the switch on the electric telescopic rod 34 is activated. The electric telescopic rod 34 drives the air extraction pump 35 to move downward. The air extraction pump 35 drives the air extraction hood 37 on the connecting box 36 to contact the rubber product body 2. At this time, the switch on the air extraction pump 35 is turned on. The air extraction pump 35 evacuates the space in contact with the rubber product body 2 by the air extraction hood 37 into a vacuum state, so that the air extraction hood 37 and the rubber product body 2 can be closely attached together. Then, the electric telescopic rod 34 is retracted upward. The electric telescopic rod 34 is used to take out the rubber product body 2 from the mold on the mold assembly 1. Then, the first motor 311 is used to drive the threaded rod 39 to rotate in the reverse direction. The threaded rod 39 drives the rubber product body 2 on the air extraction hood 37 to move to the right. At the same time, the second motor 4 is used to drive the drive shaft 41 to rotate in the reverse direction. Thus, the rubber product body 2 on the air extraction hood 37 can be conveniently moved to the unloading area for unloading. At the same time, by providing the retaining hole 43 of 270 on the retaining plate 42, the air extraction hood 37 can be conveniently and accurately moved to the material taking position and the unloading position.
