Description

Technical Field

[0001] This utility model relates to the technical field of molds, and in particular to a motor housing mold. Background Technology

[0002] Currently, in the field of motor manufacturing, traditional motor housing molds typically employ an integral core structure. This method offers certain cost advantages and high production efficiency when dealing with a single model and large-scale production. However, when it is necessary to produce motor housings with different control box structures (such as...), ... Figure 1 As shown in the diagram, a problem arises. Because the integral core is an indivisible unit, adapting it to the new control box structure requires redesigning and remanufacturing the entire mold. This not only consumes a significant amount of manpower, resources, and time, but also makes the integral core mold extremely inconvenient to maintain. Once a part of the core is damaged or worn, it often requires disassembling the entire mold and replacing the entire core, further increasing downtime and maintenance costs. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art by providing a motor housing mold, which solves the problems of high cost and inconvenient maintenance caused by the inability of the integral core to adapt to different control box structures.

[0004] The technical solution of this utility model includes a core, a cavity, a fixed module, a moving module, and a side core-pulling mechanism. The cavity includes at least two separate cavity bodies, which are separated by a separation surface. The cavity bodies are assembled to form the outer circumferential shape of the entire housing, and one of the cavity bodies forms the shape of a control box. The cavity is hollow, and the core is located in the hollow position of the cavity. The side core-pulling mechanism is connected and cooperates with the corresponding cavity body to pull each cavity body outward during mold opening.

[0005] By adopting the above technical solution, and setting the cavity as at least two separate cavities, when it is necessary to produce motor housings with different control box structures, only the cavity corresponding to the shape of the control box needs to be replaced or adjusted. There is no need to redesign and manufacture the entire mold, which greatly reduces costs and shortens the product update cycle. At the same time, the side core-pulling mechanism facilitates the pulling of each cavity outward during mold opening, making the mold opening and closing operation smoother and more efficient, improving production efficiency. Moreover, during maintenance, if a problem occurs in a part of the cavity, the individual cavity can be repaired or replaced specifically, reducing downtime and maintenance costs.

[0006] In one possible design, the cavity has four separation surfaces, which are formed by right-angle positioning surfaces and oblique guide surfaces connected end to end. The right-angle positioning surfaces are composed of two mutually perpendicular planes in the mold opening direction. The oblique guide surfaces are set along the mold opening direction and inclined to the right-angle positioning surfaces. The oblique guide surfaces on both sides of the cavity have an outwardly expanding flared shape.

[0007] With the above design, the right-angle positioning surface ensures accurate positioning of the cavity during mold closing, guaranteeing the molding accuracy of the housing; the inclined guide surface is set at an angle along the mold opening direction and has an outwardly expanding flared shape. On the one hand, it facilitates the smooth outward sliding of the cavity during mold opening, avoiding jamming. On the other hand, it can play a certain guiding and error correction role during mold closing. Even if the cavity deviates slightly from its initial position during mold closing, it can gradually return to its original position under the action of the inclined guide surface, further improving the mold closing accuracy and ensuring product quality.

[0008] In one possible design, the overall outer periphery of the cavity is conical, and a central conical hole is provided in the thickness direction of the fixed module. The outer periphery of the cavity slides and adapts to the central conical hole.

[0009] With the above design, the cavity can slide stably along the central cone hole during the mold opening and closing process. This not only plays a guiding role, making the movement trajectory of the cavity more accurate, but also enhances the stability of the cavity in the closed state, reduces cavity offset caused by material pressure and other factors, ensures the molding quality of the motor housing, and facilitates the assembly and disassembly of the mold.

[0010] In one possible design, the side core-pulling mechanism has the same number as the cavity. Each side core-pulling mechanism includes an inclined guide post and an inclined slider. The inclined guide post is obliquely inserted into the inclined slider, which is slidably mounted on the moving module. The inclined slider is also fixedly connected to the corresponding cavity.

[0011] With the above design, the cooperation between the inclined guide post and the inclined slider can transform the linear motion of the moving module during mold opening into the lateral sliding motion of the cavity driven by the inclined slider. The structure is simple and compact, and the transmission is efficient and reliable. It ensures that the cavity can be pulled out in a timely and accurate manner, achieving smooth demolding. This improves the automation level of the mold, reduces the difficulty of operation for workers, and thus improves production efficiency. Attached Figure Description

[0020] like Figures 1-7 The illustrated motor housing mold comprises a core 1, a cavity 2, a fixed module 3, a moving module 4, and a side core-pulling mechanism 5. The cavity 2 consists of at least two separate cavity bodies 21, separated by a separating surface 6. These cavities 21 can be assembled to form the outer circumferential shape of the entire motor housing 7. One cavity body 21 is specifically designed for forming the shape of a control box 71. This cavity body 21 can be replaced according to the desired shape of the control box 71, thus meeting the differentiated requirements of different motor housings 7 for the control box 71. The cavity 2 has a hollow structure, with the core 1 located precisely in the hollow portion of the cavity 2. Together, they complete the initial shaping of the motor housing 7's outline. The side core-pulling mechanism 5 connects and cooperates with the corresponding cavity body 21 to pull each cavity body 21 outwards during mold opening. When the mold is opened, the side core-pulling mechanism 5 begins to function. The side core-pulling mechanism 5 is tightly connected and cooperates with the corresponding cavity 21. Through mechanical linkage, it can pull each cavity 21 outward along a predetermined direction at the moment of mold opening, ensuring smooth mold opening. The entire process is smooth and efficient. When different shapes of control boxes 71 need to be molded, only one of the cavities 21 used for molding the control box 71 needs to be replaced. Specifically, the cavity 21 to be replaced for molding the control box 71 can be slowly removed from the mold body along the predetermined separation surface 6 path.

[0021] The number of cavities 21 is determined to be four circumferentially distributed. The separation surface 6 is formed by the right-angle positioning surface 61 and the oblique guide surface 62 connected end to end. The right-angle positioning surface 61 is composed of two mutually perpendicular planes in the mold opening direction. During the mold closing stage, these two planes can accurately restrict the position of the cavity 21 from two dimensions by virtue of their perpendicularity, ensuring that the cavity 21 fits tightly when the mold is closed, thus improving the molding accuracy of the motor housing 7. The oblique guide surface 62 is set along the mold opening direction and is inclined to the right-angle positioning surface 61. The oblique guide surfaces 62 on both sides of the cavity 21 present an outwardly expanding flared shape. During the mold opening process, the flared, angled guide surface 62 provides a smooth path for the cavity 21 to slide outward, effectively avoiding jamming caused by friction, structural interference, and other factors, ensuring smooth mold opening. During mold closing, even if the cavity 21 deviates slightly from its initial position due to previous movement or assembly, the angled guide surface 62 can use its tilting characteristics to gradually guide the cavity 21 back to the correct mold closing position, improving mold closing accuracy and ensuring product quality.

[0022] Considering the stability and guiding accuracy during mold opening and closing, the overall outer periphery of cavity 2 is designed as a conical shape. Correspondingly, a central conical hole 31 is opened in the thickness direction of the fixed module 3. The dimensions of the two are precisely matched, allowing the outer periphery of cavity 2 to slide and adapt tightly to the central conical hole 31. In actual mold opening and closing operations, cavity 2 slides stably along the central conical hole 31. The central conical hole 31 controls the movement trajectory of cavity 2, ensuring that every movement during the mold opening and closing process is precisely determined. At the same time, this tight sliding adaptation structure greatly enhances the risk of cavity 2 displacement caused by uneven material pressure, impact force, and other factors in the mold-closed state, ensuring that motor housing 7 maintains high precision throughout the molding process.

[0023] The number of side core-pulling mechanisms 5 is the same as the number of cavities 21, corresponding one-to-one. Each side core-pulling mechanism 5 includes an inclined guide post 51 and an inclined slider 52. The inclined guide post 51 is inserted into the inclined slider 52 at a specific inclined angle. The inclined slider 52 is slidably mounted on the moving module 4, and the inclined slider 52 and the corresponding cavity 21 are fixedly connected by bolts. When the mold is opened, the moving module 4 moves in the predetermined mold opening linear direction. With the help of the inclined cooperation between the inclined guide post 51 and the inclined slider 52, the linear motion of the moving module 4 is converted into the lateral sliding motion of the cavity 21 driven by the inclined slider 52. The entire transmission process is simple, clear, compact and reasonable, ensuring the high efficiency and reliability of power transmission, so that the cavity 21 can be pulled out in time and accurately at the first moment of mold opening, realizing the smooth demolding of the motor housing 7.
