Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold for mass production of stator winding end plates. Background Technology

[0002] Stator winding end plates are typically manufactured using injection molding. In existing technologies, the mold core is usually designed with only one cavity, meaning each injection molding cycle produces only one winding end plate. This reduces production efficiency, hinders mass production, and the ejector pins apply significant force during ejection before the product has fully cooled, potentially damaging or deforming the contact surface and reducing the product yield. Therefore, this paper proposes a mold for mass production of stator winding end plates. Summary of the Invention

[0003] The purpose of this invention is to provide a mass production mold for stator winding end plates in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stator winding end plate mass production mold, comprising a mold frame, an upper mold core installed within the mold frame, a lower mold core adapted to the upper mold core, and an ejection mechanism movably mounted on the mold frame; characterized in that the upper mold core and the lower mold core are provided with a plurality of winding end plate mold cavities for realizing the mass production of stator winding end plates; the lower mold core is also equipped with a pneumatic ejection mechanism to eject the product using an auxiliary ejection mechanism; the pneumatic ejection mechanism includes an ejection rod movably mounted on the lower mold core, an elastic element installed between the ejection rod and the lower mold core, and an air inlet channel for conveying gas to drive the ejection rod.

[0005] Preferably, the lower mold core is provided with a guide groove for guiding the ejector rod and a limiting groove that communicates with the guide groove and the air inlet channel and limits the elastic element.

[0006] Preferably, the limiting groove is provided with a limiting step to limit the ejector rod; the ejector rod is provided with a limiting boss.

[0007] Preferably, the diameter of the limiting boss is smaller than the inner diameter of the limiting groove; the limiting boss is also provided with a through groove to facilitate the passage of gas.

[0008] Preferably, the mold frame includes an upper mold frame for mounting the upper mold core, a lower mold frame for mounting the lower mold core and the ejection mechanism, and mold feet mounted on the lower mold frame.

[0009] Preferably, the ejection mechanism includes a plurality of guide pillars mounted on the lower mold frame, a guide sleeve mounted on the guide pillars, an ejector plate and a base plate mounted on the guide sleeve, and a plurality of ejector pins mounted on the ejector plate.

[0010] The beneficial effects of this utility model are: by providing several winding end plate cavities on the upper and lower mold cores, multiple winding end plate products can be obtained simultaneously in one production run of the upper and lower mold cores, thereby realizing the mass production of winding end plates and improving production efficiency. By using a pneumatic ejection mechanism to first eject the product pneumatically while using gas to remove some of the product's heat, the product can be cooled down faster. Then, the ejection mechanism is used to completely eject the product, preventing the ejection force from directly damaging or deforming the product, thereby improving the product's pass rate.

[0016] The following description, in conjunction with the accompanying drawings, further illustrates a mass production mold for stator winding end plates according to this utility model.

[0017] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0018] See appendix Figure 1-4As shown, this embodiment of a stator winding end plate mass production mold includes a mold frame 1, an upper mold core 2 installed inside the mold frame 1, a lower mold core 3 adapted to the upper mold core 2, and an ejection mechanism 4 movably installed on the mold frame 1. Its characteristic is that the upper mold core 2 and the lower mold core 3 are provided with a plurality of winding end plate cavities 5 for realizing the mass production of stator winding end plates. The lower mold core 3 is also equipped with a pneumatic ejection mechanism 6 that assists the ejection mechanism 4 in ejecting the products. The pneumatic ejection mechanism 6 includes an ejection rod 601 movably installed on the lower mold core 3, an elastic element 602 installed between the ejection rod 601 and the lower mold core 3, and an air inlet channel 603 for conveying gas to push the ejection rod 601 to move. By providing a plurality of winding end plate cavities 5 on the upper mold core 2 and the lower mold core 3, multiple winding end plate products can be obtained simultaneously in one production run, thereby realizing the mass production of winding end plates and improving production efficiency. By using the pneumatic ejection mechanism 6 to first pneumatically eject the product while using gas to remove some of the product's heat, the product's cooling speed is accelerated. Then, the ejection mechanism 4 is used to completely eject the product, preventing damage or deformation to the product during the ejection process, thereby improving the product's qualification rate.

[0019] See appendix Figure 2 As shown, the lower mold core 3 is provided with a guide groove 604 for guiding the ejector rod 601, and a limiting groove 605 communicating with the guide groove 604 and the air inlet channel 603 and limiting the elastic element 602; the limiting groove 605 is provided with a limiting step 606 for limiting the ejector rod 601; the ejector rod 601 is provided with a limiting boss 607; the diameter of the limiting boss 607 is smaller than the inner diameter of the limiting groove 605; the limiting boss 607 is also provided with a through groove 608 to facilitate the passage of gas; one end of the limiting groove 605 is plugged. The gas enters the air inlet channel 603 and then enters the limiting groove 605, pushing the ejector rod 601 to move. The ejector rod 601 moves along the guide groove 604, compressing the elastic element 602. The ejector rod 601 ejects the product outward. At the same time, the compressed gas passes through the through groove 608 on the limiting boss 607 and the guide groove 604 and blows towards the product, thereby carrying away some of the heat from the product and the lower mold core 3, accelerating the cooling speed of the product, and reducing the ejection force of the ejector mechanism 6 on the product, preventing damage or deformation to the product.

[0020] See appendix Figure 1As shown, the mold frame 1 includes an upper mold frame 101 for mounting the upper mold core 2, a lower mold frame 102 for mounting the lower mold core 3 and the ejection mechanism 4, and mold feet 103 mounted on the lower mold frame 102; the ejection mechanism 4 includes a plurality of guide posts 401 mounted on the lower mold frame 102, guide sleeves 402 mounted on the guide posts 401, ejector plates 403 and base plates 404 mounted on the guide sleeves 402, and a plurality of ejector pins 405 mounted on the ejector pins 405.

[0021] In this invention, the injection molding machine delivers molten plastic through the nozzle 7 to the runner of the upper mold, and then flows through the runner to the mold cavities 5 of each winding end plate for molding. After the molten plastic is molded into a product, the injection molding machine drives the mold to open, separating the upper mold core 2 and the lower mold core 3. Then, the air pump delivers gas to the air inlet channel 603. The gas entering the air inlet channel 603 enters the limiting groove 605 and squeezes the ejector rod 601, pushing the ejector rod 601 outward along the guide groove 604 to compress the elastic element 602. 01 The product is ejected outward from the runner, and at the same time, the gas moves outward along the guide groove 604 and blows towards the runner, so that the gas can carry away some of the heat of the lower mold core 3 and the product, and accelerate the cooling speed. Then the injection molding machine drives the ejection mechanism 4 to move forward and uses the ejector pin 405 to eject the product outward, so that the product is completely separated from the winding end plate mold cavity 5. Then the injection molding machine drives the ejection mechanism 4 to reset, and at the same time the air pump stops delivering gas. The elastic element 602, due to the lack of gas pressure, uses its own elasticity to drive the ejector rod 601 to reset, and the subsequent injection continues.

[0022] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
