Description

Technical Field

[0001] The utility model relates to the field of annular iron core manufacturing molds, in particular to a mold used for iron core production. Background Art

[0002] Motor generally refers to an electric motor, which is a device that converts electrical energy into mechanical energy. A motor ring core refers to a motor core structure that consists of a series of round or oval iron sheets that are threaded onto the motor shaft and used as the core of the rotor.

[0003] During the manufacturing of the motor annular core in the prior art, workers are required to perform multiple manufacturing operations. Manual manufacturing not only easily leads to low manufacturing quality of the annular core, but also increases the workload of workers. In addition, during the related operations of gluing, overlapping, and guiding and fixing, manual manufacturing easily causes certain errors between individuals, which in turn affects the related operations of overlapping, guiding and fixing the cores, making its subsequent processing and use more inconvenient. Summary of the invention

[0004] The purpose of the utility model is to provide a mold for core production in view of the shortcomings and defects in the prior art. The structure enables the semi-finished motor product annular core material to be glued, overlapped, guided and fixed, and formed through external heating as an integrated production operation as required, which not only reduces labor costs to a certain extent, saves production time and improves product quality, but also improves and effectively guarantees product production quality and efficiency.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mold for iron core production, which includes an upper mold core rod 1, a positioning mold sleeve 4, and a lower mold cushion sleeve 5. One end of the upper mold core rod 1 is sleeved in the inner cavity of the lower mold cushion sleeve 5, and an annular iron core 2 is provided between the upper mold core rod 1 and the lower mold cushion sleeve 5. The annular iron core 2 and the lower mold cushion sleeve 5 are both arranged in the inner cavity of the positioning mold sleeve 4.

[0006] Furthermore, one end surface of the annular core 2 abuts against one end surface of the lower die cushion sleeve 5 .

[0007] Furthermore, the surface of the upper mold core rod 1 is provided with a wear-resistant coating.

[0008] Furthermore, an upper positioning cushion sleeve 3 is provided on one side of the positioning mold sleeve 4 , and a lower positioning cushion sleeve 6 is provided on the other side of the positioning mold sleeve 4 .

[0009] Furthermore, a tungsten steel insert is embedded inside the positioning mold sleeve 4.

[0010] After adopting the above technical scheme, the beneficial effect of the utility model is: this structure can make the semi-finished motor product annular core material can be glued and overlapped, guided and fixed, and formed through external heating and other processes as an integrated production operation as required, which can not only reduce labor costs to a certain extent, save production time and improve product quality, but also improve and effectively ensure product production quality and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0016] Explanation of the accompanying drawings: upper die core rod 1, annular iron core 2, upper positioning sleeve 3, positioning die sleeve 4, lower die sleeve 5, lower positioning sleeve 6. DETAILED DESCRIPTION Example

[0017] See also Figure 1-Figure 4 As shown, the technical solution adopted in this specific embodiment is: it includes an upper mold core rod 1, a positioning mold sleeve 4, and a lower mold cushion sleeve 5, one end of the upper mold core rod 1 is sleeved in the inner cavity of the lower mold cushion sleeve 5, and an annular iron core 2 is provided between the upper mold core rod 1 and the lower mold cushion sleeve 5, and the annular iron core 2 and the lower mold cushion sleeve 5 are both arranged in the inner cavity of the positioning mold sleeve 4.

[0018] More specifically, one end face of the annular core 2 abuts against one end face of the lower die cushion 5. The lower die cushion 5 can bear pressure, fix and limit the end face of the annular core 2.

[0019] More specifically, the surface of the upper mold core rod 1 is provided with a wear-resistant coating. By spraying or plating a layer of coating on the surface of the upper mold core rod 1, it can meet specific production requirements with product size and mold during long-term operation, such as high surface hardness, wear resistance, easy demoulding products, etc.

[0020] More specifically, an upper positioning sleeve 3 is provided on one side of the positioning mold sleeve 4, and a lower positioning sleeve 6 is provided on the other side of the positioning mold sleeve 4. The upper positioning sleeve 3 can guide the product and can also be fixed and limited with the positioning mold sleeve 4 and the lower positioning sleeve 6, and the lower positioning sleeve 6 also has the function of fixing and limiting the lower mold.

[0021] More specifically, the interior of the positioning die sleeve 4 is inlaid with tungsten steel inserts. By inlaying the interior of the positioning die sleeve 4 with tungsten steel inserts, the positioning die sleeve 4 has the characteristics of wear resistance, high hardness, fine surface finish, and stable dimensions of hot-processed products, ensuring that the positioning die sleeve 4 has better effects and service life in fixing and guiding the product shape. Example

[0022] The difference between this embodiment and the first embodiment is that the surface of the positioning mold sleeve 4 is provided with a wear-resistant coating. The wear-resistant coating can replace the alloy material of the tungsten steel embedded inside it, which has lower cost and can also meet the characteristics of high surface hardness, wear resistance, stable product size and easy demoulding.

[0023] The working principle of the utility model is as follows: firstly, a plurality of annular iron cores 2 are overlapped and guided by the upper positioning cushion sleeve 3 to be placed in the corresponding discharge position of the inner cavity of the positioning mold sleeve 4; then, the special adhesive applied on both sides of the annular iron core 2 is heated to the predetermined requirements at the mold positioning mold sleeve 4 by the corresponding auxiliary function; at the same time, the upper mold core rod 1 is pressed down by the special equipment to press the single-piece annular iron core 2 in the positioning mold sleeve 4 and between the lower mold cushion sleeve 5 according to the product requirements, and the inner hole and the shape of the product are fixed and corrected to meet the predetermined bonding and overlapping requirements. After the predetermined requirements are met, the corresponding pressing equipment returns to its original position. At the same time, the upper mold core rod 1 returns to its original position. After being pressed, the product is also ejected by the equipment ejection mechanism and then smoothly ejected by the lower mold sleeve 5 to the predetermined position to take out the annular iron core 2 that has been glued and folded. In order to prevent the product from being deformed when it is returned and taken out, the lower mold sleeve 5 can be installed in the lower positioning sleeve 6 mold, thereby returning to the initial process of the initial single-piece annular iron core 2 placement position cycle. Among them, the positioning mold sleeve 4 can not only be embedded with tungsten steel inserts inside, but also can be specially coated on the surface to meet specific production requirements. It only needs to meet the characteristics of high surface hardness, wear resistance, stable product size and easy demolding.

[0024] 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.
