Description

[0002] The relay is an electrical control device, which is a kind of electrical appliance that makes the controlled quantity change by a predetermined step in the electrical output circuit when the input quantity (excitation quantity) changes to a specified requirement, and the armature magnetic sheet is an indispensable part of the relay.

[0003] In the production process of the armature magnetic sheet, the magnetic powder and the resin powder are mixed and granulated, and then the granulated particles are injected into the injection molding machine for heating and melting, so as to have good fluidity. In this state, the granulated particles are injected into the metal mold with an oriented magnetic field in a molten state, and then the required complex-shaped armature magnetic sheet is formed after cooling, and then the mold is removed to complete the production.

[0045] In the embodiment, with reference to Figure 3 The side wall of the mounting plate 220 is provided with a receiving groove 220c matched with the demolding plate 220b, which is used for conveniently receiving the demolding plate 220b during injection to avoid the influence of the demolding plate 220b on the shape of the product formed in the mold cavity 230a during injection.

[0046] In the embodiment, with reference to Figure 3 The inner wall of the bottom plate 210 is provided with a lead screw 210a with opposite threads at two ends and a sliding rod 210b located at the two sides of the lead screw 210a, and the two mold bases 230 are respectively sleeved at the two ends of the lead screw 210a and the sliding rod 210b, so that the two mold bases 230 are away from or close to each other along the lead screw 210a and the sliding rod 210b under the limiting action of the sliding rod 210b when the lead screw 210a rotates.

[0047] In the embodiment, with reference to Figures 1-2One of the side walls of the mold base 230 is provided with a sawtooth plate 230b for driving the gear plate 430d-42 to rotate when the mold is opened or closed.

[0048] With reference to Figures 1-3 The toxic gas removal mechanism 300 is used to remove the harmful gas generated in the injection box 100 when the mechanism works. The toxic gas removal mechanism 300 includes a combustion box 310 which is in communication with the injection box 100 and burns and decomposes the internal toxic gas when the mechanism works, so that the harmful gas is decomposed at high temperature by combustion.

[0049] In this embodiment, with reference to Figures 1-3 The toxic gas removal mechanism 300 further includes a first gas guide pipe 320 having one end connected to the side wall of the combustion box 310 and the other end connected to the injection box 100, and the side wall of the first gas guide pipe 320 is provided with a solenoid valve, and an external connecting pipe 330 located at the bottom of the combustion box 310 and in communication with the outside.

The external connecting pipe 330 is used to communicate with the external air, and when the external connecting pipe 330 is opened, the oxygen in the external air enters the combustion box 310, so that the igniter in the combustion box 310 ignites and burns in cooperation with the oxygen. The solenoid valve is used to close the first gas guide pipe 320 when the combustion box 310 is burning, so as to avoid the expansion of air generated by burning entering the injection box 100 through the first gas guide pipe 320.

[0050] With reference to Figures 1-6 The driving mechanism 400 is installed on one side of the injection box 100, and the driving mechanism 400 drives the two mold bases 230 to close or open when the mechanism works, so as to complete the injection.

When the combustion chamber 310 is burning, the air expanded after combustion enters the air inlet pipe 440a-1 and the second air guide pipe 440a through the guide pipe, the gas in the second air guide pipe 440a enters the inner connecting pipe 440b through the air inlet 440b-1, then the side wall of the outer telescopic pipe 440c is extruded, at this time the outer telescopic moves outward along the inner connecting pipe 440b to push the demolding plate 220b to move and demold, at this time the spring 440b-2 is stretched, after the combustion chamber 310 stops burning, no gas enters the inner connecting pipe 440b, the outer telescopic pipe 440c shrinks under the resetting action of the spring 440b-2, thereby driving the demolding plate 220b to restore to the original state, the end of the inner connecting pipe 440b close to the demolding plate 220b is of an open structure for facilitating the gas in the inner connecting pipe 440b to enter the outer telescopic pipe 440c to extrude the side wall of the outer telescopic pipe 440c, the side wall of the end of the outer telescopic pipe 440c away from the demolding plate 220b is provided with a gas vent hole 440c-1, reference Figures 4-5 for pushing the demolding plate 220b out after the outer telescopic pipe 440c, at this time the gas vent hole 440c-1 is separated from the outer side wall of the inner connecting pipe 440b, thereby the internal gas is discharged, avoiding the gas remaining in the inner wall of the outer telescopic pipe 440c and the inner connecting pipe 440b, causing the air pressure in the inner wall of the inner connecting pipe 440b to always remain large, thereby the outer telescopic pipe 440c cannot automatically shrink after demolding, the demolding plate 220b cannot automatically restore to the original state, thereby the next injection molding production work cannot be continuously carried out;

[0058] The one end of the air inlet pipe 440a-1 far from the second air guide pipe 440a is connected with the top of the combustion box 310 through a pipe, so that the expanded gas generated when the combustion box 310 is combusting enters into the air inlet pipe 440a-1 through the pipe, and then enters into the second air guide pipe 440a;

[0059] In the embodiment, the inner wall of the mounting plate 220 is provided with an air outlet opening to the outside, so as to discharge the gas discharged through the air vent 440c-1 from the inside of the mounting plate 220.

[0060] In the embodiment, the specific use process is as follows: referring to Figure 4 , the magnetic powder and the original pigment particles are added into the injection molding box 100 through the feeding port, and then are heated and melted to be injected into the mold cavity 230a. The harmful gas generated in the injection molding box 100 at high temperature expands and enters into the combustion box 310. When the molded product in the mold cavity 230a is cooled, referring to Figure 5 , the driving mechanism 400 drives the two mold seats 230 to perform mold splitting. When the two mold seats 230 perform mold splitting, the combustion box 310 is driven to perform combustion, so as to decompose the harmful gas. When the combustion box 310 is combusting, the stripper plate 220b is automatically moved to push out the product molded on the mold core 220a, so as to complete stripping. After stripping, the driving mechanism 400 drives the two mold seats 230 to perform mold closing. When the two mold seats 230 perform mold closing, the combustion box 310 is driven to stop combustion, so as to avoid waste of fuel. After the combustion box 310 stops combustion, the stripper plate 220b automatically restores to the original state, so as to facilitate the next injection molding and stripping, and thus the external driving force is not needed for stripping, so that the energy-saving and emission-reducing effect is achieved.

[0061] Although the present application has been described with reference to the embodiments above, various improvements can be made thereto and equivalent replacements can be made to the components thereof without departing from the scope of the present application. In particular, as long as there is no structural conflict, each feature in the embodiments disclosed in the present application can be combined with each other in any manner, and the combinations are not exhaustively described in the present specification only for the purpose of omitting the length and saving the resources. Therefore, the present application is not limited to the specific embodiments disclosed herein, but includes all the technical solutions falling within the scope of the claims.
