Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeve processing, in particular to a motor shaft sleeve vulcanization mould which is easy to demould. Background Art

[0002] The shaft sleeve of the motor shaft also plays a sealing role. It is mostly made by injection molding, and multiple pieces are molded at the same time. For this reason, a pouring channel is arranged on the lower mold, and the sleeve is molded by injection molding from the upper mold pouring port into the pouring channel. However, the edge of the sleeve after molding is adhered to the pouring channel. The traditional method is to remove the upper mold, take out the sleeve and the pouring channel as a whole, and then cut the sleeve off by cutting. Obviously, this method has many processes and low work efficiency, which correspondingly increases the product production cost. Utility Model Content

After forming, the external air pump inputs air pressure to the inner cavity of the annular connecting ring through the connecting pipe. Then, the internal air pressure of the annular connecting ring increases, and the expansion supports the sleeve. At this time, the reset spring is stretched, and then the upper die seat rises. At this time, the forming pressure head rises, driving the sleeve to rise from the forming groove to complete demoulding. After rising, the connecting pipe extracts the gas in the annular connecting ring, and then the reset spring contracts to pull the annular connecting ring to reset, losing the tension on the inside of the sleeve. Then the sleeve falls to complete demoulding, and the material can be discharged quickly. The shape of the annular connecting ring can be maintained in a normal state through the setting of the pull rod and the reset spring, and it can be reused for a long time.

[0005] As a further solution of the utility model: the connection between the return spring and the inner wall of the annular connecting ring is circumferentially arranged on the periphery of the connection point between the pull rod and the annular connecting ring. Through the setting of the pull rod, the shape of the annular connecting ring can be kept without significant changes, forming effective support.

[0006] As a further solution of the utility model: the inner cavity of the lower die seat is provided with a movable groove connected to the molding groove, and the inner cavity of the movable groove is slidably connected with a baffle plate driven by a cylinder. When in use, after the sleeve is demolded and falls off the molding pressure head, the baffle plate is driven by the cylinder to move from the movable groove to above the molding groove, thereby blocking the molding groove and preventing the fallen sleeve from re-entering the molding groove.

[0007] As a further solution of the utility model: the side of the lower die seat is fixedly connected with a blowing hopper connected to the air source. Through the setting of the blowing hopper, the sleeve falling on the upper part of the lower die seat is blown to one side of the lower die seat by the airflow of the blowing hopper for centralized collection, so that the material can be discharged quickly.

[0008] As a further solution of the utility model: a plurality of pull rods are provided and are evenly distributed on the surface of the support rod, and the plurality of pull rods are connected to the annular connecting ring, which can ensure the overall stability of the annular connecting ring.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The utility model inputs air pressure into the inner cavity of the annular connecting ring through the connecting pipe, the air pressure inside the annular connecting ring increases, expands to support the shaft sleeve, drives the shaft sleeve to rise from the molding groove, and completes demoulding. After rising, the connecting pipe extracts the gas in the annular connecting ring, the annular connecting ring is reset, and the tension force on the inside of the shaft sleeve is lost. Then the shaft sleeve falls to complete demoulding, and the material can be discharged quickly. The shape of the annular connecting ring in a normal state can be maintained by setting the pull rod and the reset spring, and it can be reused for a long time.

[0011] 2.
