Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a demoulding device for rubber processing. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer. Rubber is divided into natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from plants such as rubber trees and rubber grass. After the rubber is formed in the mold, a demolding device is needed to demold the rubber in the lower mold of the mold.

[0003] Announcement No.: CN210999639U includes two support plates, the tops of the two support plates are fixedly connected with U-shaped frames, and the demoulding machine of the rubber processing equipment has a better demoulding effect by arranging an electric telescopic rod and a mounting plate, etc., and the electric telescopic rod is used to drive the suction cup to move, so that the rubber in the mold can be sucked up. The demoulding agent is arranged inside the storage box, so that the rubber in the mold can be taken out. The second groove and the connecting column are arranged, so that the demoulding machine of the rubber processing equipment has a better shock-absorbing effect when moving, and the spring is arranged to make the demoulding machine of the rubber processing equipment have a better shock-absorbing effect.

[0004] The applicant found that there are some shortcomings in use: the rubber molding mold usually includes an upper mold and a lower mold. After molding, the upper mold rises a certain distance to form a certain gap with the lower mold, and the rubber is located in the lower mold. For some small rubber products such as rubber discs, the mold itself is small, and the distance between the upper and lower molds after separation is also small. However, due to the overall thickness of the patent, it may not be possible to enter the gap between the upper and lower molds, making it inconvenient to demold smaller molds.

[0005] Therefore, the utility model designs a demoulding device for rubber processing to solve the problems existing in the prior art. Utility Model Content

[0006] The utility model aims to provide a demoulding device for rubber processing to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a demolding device for rubber processing, comprising: a base, a demolding mechanism is provided above the base, a unloading mechanism is provided on the demolding mechanism for facilitating the unloading of the demolding mechanism, an entry and exit mechanism is provided on the top of the base for driving the demolding mechanism to move, universal wheels are provided at the four corners of the bottom of the base, and a handrail is installed on one side of the top of the base.

[0008] Preferably, the demoulding mechanism includes an electric cylinder, the output end of the electric cylinder is connected to a connecting block, the connecting block is provided with an air pipe, the bottom of the air pipe is connected to a hollow disk, the bottom of the hollow disk is provided with a plurality of suction nozzles, and one end of the electric cylinder is equipped with a high-pressure air pump connected to the air pipe, the thickness of the air pipe and the hollow disk is narrow, which is convenient for demoulding smaller molds.

[0009] Preferably, the unloading mechanism includes a groove, which is opened at one end of the connecting block. A rotating shaft rotatably mounted with the connecting block is provided in the groove. A connecting disk is installed in the middle of the outer side of the rotating shaft. One side of the connecting disk is connected to the air pipe. The rotating shaft rotates 90 degrees, so that the air pipe drives the hollow disk to rotate 90 degrees, so that the demolded rubber is rotated away from the top of the base, and then the high-pressure air pump is turned off, the rubber can fall automatically, and a collection box can be placed directly below the hollow disk.

[0010] Preferably, the entry and exit mechanism includes a bottom groove, which is opened on a side of the top of the base away from the armrest, and a screw rod rotatably mounted with the base is provided in the bottom groove, and a screw block is slidably mounted on the outer wall of the screw rod through a thread, and the screw block is slidably connected to the bottom groove, and the top of the screw block is connected to the bottom of the electric cylinder. The screw rod rotates forward and backward, so that the screw block can move left and right in the bottom groove, thereby conveniently driving the hollow disk in and out of the gap between the upper and lower molds.

[0011] Preferably, rollers are provided at the four corners of the bottom of the wire block, and the rollers are rollingly connected to the base. The movement of the wire block drives the rollers to roll on the base, which can reduce the friction between the wire block and the base.

[0012] Preferably, a battery box is provided on the top of the base on one side of the armrest, and a PLC controller is provided on the top of the battery box. Batteries are conveniently placed in the battery box to power electrical components, and the PLC controller is convenient for staff to control.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a demoulding mechanism and an in-and-out mechanism, and the electric cylinder drives the connection block to rise and fall to adjust the height of the hollow disk. After the hollow disk is parallel to the gap between the upper and lower molds, the screw rod rotates to drive the wire block to move, so that the hollow disk can enter the gap. Then the electric cylinder descends, so that the suction nozzle at the bottom of the hollow disk contacts the rubber in the lower mold. The high-pressure air pump is started to generate negative pressure to absorb the rubber. Then the screw rod is reversed to make it descend and leave between the upper and lower molds to complete demoulding. Since the overall thickness of the hollow disk and the air pipe is relatively narrow, it is convenient to demould in a smaller mold, thereby improving practicality.

[0015] 2. The utility model sets a material discharge mechanism. After the rubber leaves the mold, the rotating shaft rotates 90 degrees, so that the air pipe drives the hollow disk to rotate 90 degrees, so that the rubber leaves the top of the base, and then the electric cylinder descends to drive the rubber to the lowest point. When the high-pressure air pump is turned off, the rubber can fall automatically. A collection box can be placed just below the hollow disk to collect the rubber, which is convenient for the discharge of the rubber after demolding. BRIEF DESCRIPTION OF THE DRAWINGS
