Description

Technical Field

[0001] The utility model relates to the field of iron core manufacturing moulds, in particular to an iron core self-adhesive mould structure. Background Art

[0002] The iron core refers to the part of the motor that is used to form the magnetic circuit, usually made of silicon steel sheets. It is an important component of the motor, used to conduct and concentrate the magnetic field, thereby realizing the conversion between electrical energy and mechanical energy. Usually, the iron core is composed of stacked multiple thin silicon steel sheets. This is because silicon steel sheets have low hysteresis and low remanence characteristics, which can effectively reduce the energy loss of the iron core. At the same time, silicon steel sheets also have high resistance, which can reduce eddy current losses.

[0003] The existing iron core mold is very time-consuming for the iron core processing process, and the production efficiency cannot be improved. The positioning accuracy of the iron core during the bonding process cannot be guaranteed, so the quality of the iron core manufactured in this way is not high. Summary of the invention

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a core self-adhesive mold structure, which includes:

[0006] The upper die mechanism 1 includes a limit assembly 11 for inserting the core material and a cushion sleeve 12 movably sleeved on the limit assembly 11; the cushion sleeve 12 is used to shape and withdraw the core material on the corresponding auxiliary material withdrawal equipment after the core material is processed, so as to ensure that the processed product is consistent with the precision in the mold processing after withdrawal and is not damaged by withdrawal;

[0007] The lower mold mechanism 2 includes a guide mold sleeve 21 and a positioning mold sleeve 22 adapted to the limiting assembly 11, and the positioning mold plays the role of pressure bearing and fixed limiting; the guide mold sleeve 21 is connected to the positioning mold sleeve 22, and the guide mold sleeve 21 is located above the positioning mold sleeve 22.

[0008] Furthermore, the limiting assembly 11 includes an inner mold core rod 111 located on the center line of the upper mold mechanism 1 and an insert 112 surrounding the inner mold core rod 111 .

[0009] Furthermore, the upper mold mechanism 1 further comprises an inner mold fixing sleeve 13 and a pressure cover 14 . The limiting assembly 11 is inserted into the inner mold fixing sleeve 13 and the limiting assembly 11 is fixed by the pressure cover 14 .

[0010] Furthermore, the upper mold mechanism 1 also includes an auxiliary plug-in board 15 for driving the cushion sleeve 12 to move along the limiting assembly 11. It is used to assist in material stripping to facilitate efficient material stripping of the corresponding inner mold insert 112 and the processed product;

[0011] Furthermore, the positioning mold sleeve 22 includes a positioning cushion sleeve 221 and a lower positioning cushion sleeve 222 sleeved on the periphery of the positioning cushion sleeve 221 . The positioning cushion sleeve 221 is provided with a limiting groove 2211 matched with the insert 112 and a limiting hole 2212 matched with the inner mold core rod 111 .

[0016] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: the core material is sleeved on the limiting component to ensure the flatness and verticality of the core material for the first time; the limiting component and the positioning sleeve are plugged together to ensure the flatness and verticality of the core material for the second time. The double restriction prevents the core material from being deformed during the pressing and bonding process, thereby ensuring the positioning accuracy.

[0017] This structure integrates the processes of gluing, aligning, fixing, and externally heating the semi-finished core materials into an integrated production operation according to product requirements; the staff only needs to load and unload the materials, which reduces labor costs to a certain extent, thereby saving production time and improving product quality.

DETAILED DESCRIPTION

[0022] See also Figure 1-2 As shown, the technical solution adopted in this specific embodiment is: an iron core self-adhesive mold structure, which includes: an upper mold mechanism 1 and a lower mold mechanism 2 that are closely matched;

[0023] The specific upper mold mechanism 1 includes a limit assembly 11, a cushion sleeve 12, an inner mold fixing sleeve 13, a pressure cover 14, and an auxiliary plug-in board 15 for driving the cushion sleeve 12 to move along the limit assembly 11. The limit assembly 11 is plugged into the inner mold fixing sleeve and fixed by the pressure cover 14. More specifically, the limit assembly 11 includes an inner mold core rod 111 embedded in the center line of the inner mold fixing sleeve and coated with a wear-resistant coating on the upper surface, and an insert 112 embedded in the inner mold fixing sleeve and surrounding the inner mold core rod 111. In this embodiment, the auxiliary plug-in board 15 is U-shaped, and a strip groove 131 for inserting the auxiliary plug-in board 15 is provided on the outer wall of the inner mold fixing sleeve 13, and the strip groove 131 is connected to the cushion sleeve 12.

[0024] The specific lower die mechanism 2 includes a lower die guide die sleeve 23, a guide die sleeve 21 and a positioning die sleeve 22 which are connected in sequence. More specifically, the positioning die sleeve 22 includes a positioning cushion sleeve 221 and a lower positioning cushion sleeve 222 sleeved on the periphery of the positioning cushion sleeve 221. The positioning cushion sleeve 221 is provided with a limiting groove 2211 adapted to the insert 112 and a limiting hole 2212 adapted to the inner die core rod 111. In this embodiment, the guide die sleeve 21 is provided with a through hole 211 adapted to the specifications of the core material and the surface of the guide die sleeve 21 is provided with a wear-resistant coating.

[0025] The working principle of the utility model is as follows: In the first step, the core material is passed through the inner mold core rod 111 and the insert 112 and placed on the upper end of the cushion sleeve 12. After the core material is installed, the upper mold mechanism 1 and the lower mold mechanism 2 are close to each other.

[0026] In the second step, after the core material is installed, the upper mold mechanism 1 and the lower mold mechanism 2 are driven by an external driving device (not shown in the figure) to approach each other, and the limiting assembly 11 passes through the lower mold guide sleeve 23 and the guide sleeve 21 until the insert 112 and the inner mold core rod 111 are respectively inserted into the limiting groove 2211 and the limiting hole 2212 on the positioning sleeve 221, and then stop approaching.

[0027] In the third step, the lower positioning sleeve 222 is heated by an external heating device (not shown in the figure) so that the adhesive on both sides of the core material can meet the bonding requirements. At the same time, the external driving device (not shown in the figure) drives the upper mold mechanism 1 and the lower mold mechanism 2 closer together again until the core material abuts against the end face of the positioning sleeve 221 and applies a certain downward pressure to the core material.

[0028] Step 4: After the bonding is completed, the external driving device stops pressurizing and returns to its original position, so that the upper mold mechanism 1 and the lower mold mechanism 2 are separated. Since the bonded iron core material is still sleeved on the limit assembly 11, the auxiliary plug-in board 15 is inserted into the strip groove 131 under the drive of the external device (not shown in the figure), and then the cushion sleeve 12 is driven to move along the length direction of the limit assembly 11, so that the bonded iron core material is effectively and finely taken out to prevent deformation during the removal. After the material is taken out, the auxiliary plug-in board 15 and the cushion sleeve 12 are reset, and the one-cycle process of the device is completed.

[0029] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
