Description

Technical Field

[0001] This utility model belongs to the field of magnetic ring mold technology, specifically relating to a pneumatic demolding bracket for processing magnetic ring components. Background Technology

[0002] Existing magnetic ring demolding methods are generally manual, which can easily damage the magnetic ring. Among them, the "Automatic Demolding Magnetic Ring Pressing Mold" disclosed in application number "CN202121126091.5" is an increasingly mature technology. The operation of the drive mechanism drives the ejector mechanism to move up and down. When the ejector mechanism moves upward, it pushes the pressed magnetic ring upward, so that the magnetic ring is separated from the mold body and completes the automatic demolding. It will not cause uneven force on the magnetic ring and damage to the magnetic ring. However, this device still has the following defects: In actual use, the above device can only lift the magnetic ring, and the injection molded part will stick to the inner wall of the upper mold and the lower mold, and cannot effectively separate the injection molded part from the upper mold and the lower mold. Utility Model Content

[0003] The purpose of this utility model is to provide a pneumatic demolding bracket for processing magnetic ring components, which aims to solve the problem in the prior art that injection molded parts will stick to the inner walls of the upper and lower molds and cannot be effectively separated from the upper and lower molds.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a support base, a placement cavity in the center of the support base, a lower mold on the top of the inner wall of the placement cavity, guide rods on both sides of the top of the support base, a top plate on the top of the guide rods, hydraulic lifting rods fixedly installed on both sides of the bottom of the top plate, an upper mold at the bottom of the hydraulic lifting rods, an injection pipe connected to the top of the upper mold, a synchronous pneumatic rod at the bottom of the inner wall of the placement cavity, a support frame fixedly connected to the top of the synchronous pneumatic rod, a support rod on the top of the support frame, movable holes at the four corners of the bottom of the inner wall of the lower mold, the support rod movably connected to the movable holes, and a tray on the top of the support rod.

[0005] In an embodiment of the pneumatic demolding bracket for processing magnetic ring components according to this utility model, guide grooves are provided on both sides of the upper mold, and the guide rod is slidably connected in the guide groove.

[0006] In this solution, when the hydraulic lifting rod moves the upper mold, it moves along the outer wall of the guide rod through the guide groove to guide the movement direction of the upper mold and improve the stability of the upper mold movement.

[0007] In an embodiment of the pneumatic demolding bracket for processing magnetic ring components according to this utility model, a heat-insulating sealing gasket is provided at the bottom of the inner wall of the movable hole.

[0008] In this design, when the support rod moves within the movable hole, leakage of the injection molding material is prevented by a heat-insulating sealing gasket.

[0009] In an embodiment of the pneumatic demolding bracket for processing magnetic ring components according to this utility model, positioning posts are provided at the four corners of the bottom of the upper mold, and positioning holes are provided at the four corners of the top of the lower mold. The positioning posts and positioning holes are interlocked.

[0010] In this design, after the upper and lower molds are connected, the positioning pins are inserted into the positioning holes to improve the tightness of the connection between the upper and lower molds.

[0011] In an embodiment of the pneumatic demolding bracket for processing magnetic ring components according to this utility model, a receiving cavity is provided at the top of the inner wall of the upper mold, and an elastic heat-resistant airbag is provided in the receiving cavity. A micro vacuum pump is provided on one side of the upper mold, and the pumping end of the micro vacuum pump passes through one side of the support base and is sealed and connected to the elastic heat-resistant airbag.

[0012] In this solution, before the upper mold closes for injection molding, a miniature vacuum pump evacuates the air from the elastic heat-resistant airbag. The elastic heat-resistant airbag adheres to the inner wall of the cavity. After the upper and lower molds are combined for injection molding, the elastic heat-resistant airbag is inflated to lift the magnetic ring injection molded part in the upper mold for demolding, thus avoiding adhesion.

[0013] In an embodiment of the pneumatic demolding bracket for processing magnetic ring components according to this utility model, an air inlet pipe is provided on the other side of the upper mold. One end of the air inlet pipe is sealed and connected to one side of the elastic heat-resistant airbag, and the other end of the air inlet pipe is connected to an electromagnetic vent valve.

[0014] In this design, after injection molding is completed, the electromagnetic vent valve opens, causing the negative pressure elastic heat-resistant airbag to inflate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The air in the elastic heat-resistant airbag is evacuated by a miniature vacuum pump. The airbag fits against the inner wall of the cavity. After the upper and lower molds are aligned, the positioning pin is inserted into the positioning hole to improve the tightness of the connection between the upper and lower molds. At this time, the injection tube performs injection molding. After injection molding is completed, the upper mold is raised. At this time, the electromagnetic vent valve is opened, which inflates the negative pressure elastic heat-resistant airbag and lifts the magnetic ring injection part in the upper mold for demolding, preventing it from sticking to the inner wall of the upper mold. At the same time, the pneumatic rod lifts the support frame, and the support rod in the movable hole lifts the tray, lifting the magnetic ring and demolding the magnetic ring in the lower mold.
