[0002] The motor housing end cover is an external component that is installed on the end cover of the motor to provide an additional protective layer, preventing external factors such as dust, moisture, and oil from damaging the inside of the motor, while also enhancing the appearance of the motor. Because the shape of the motor housing end cover sleeve is quite complex, in order to ensure its dimensional accuracy, the motor housing end cover sleeve is currently mostly produced by die casting molds. However, in traditional die-casting technology, after the mold is opened, part of the motor housing end cover jacket will stick to the inside of the cavity. Moreover, due to the lack of effective demolding measures, it is very easy for the demolding of the motor housing end cover jacket to take a long time, which affects the production efficiency of the motor housing end cover jacket.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please see Figure 1-4 A die-casting mold for an end cover of a motor housing, comprising: The lower mold body 1 has a lower cavity 2 at its top and a fixed mold insert A3 integrally formed in the middle of the lower cavity 2. Pushing components 4 are assembled at all four ends of the lower mold body 1. The upper mold body 5 has an upper cavity 6 at its bottom end. A fixed mold insert B7 is integrally formed in the middle of the upper cavity 6. A forming block 8 is provided at each of the four ends of the upper cavity 6. The forming block 8 is used to cooperate with the fixed mold insert A3, the push component 4 and the fixed mold insert B7 to form a complete motor housing end cover outer cavity. More specifically, the fixed mold insert A3 is made of powder metallurgy and die-cast aluminum. Through the material characteristics of the fixed mold insert A3, it can be adapted to the processing of complex shapes of the fixed mold insert A3, and can reduce material waste and improve material utilization. More specifically, the fixed mold insert B7 is provided with a PVD coating. PVD coating is a technology that deposits material onto the surface of a workpiece through physical methods under vacuum conditions. PVD coatings typically have very high hardness, far exceeding that of many common metal materials. Due to its high hardness, the PVD coating can significantly improve the wear resistance of the workpiece and extend the service life of the fixed mold insert B7. Please refer to Figure 2 In this embodiment, a vacuum interface 14 is provided on one side of the bottom end of the upper mold body 5, and the end of the vacuum interface 14 near the upper cavity 6 is connected to the upper cavity 6. More specifically, by setting up the vacuum interface 14, after the upper mold body 5 and the lower mold body 1 are closed, the external vacuum equipment is connected to the vacuum interface 14, so that the air in the lower cavity 2 and the upper cavity 6 can be extracted, thereby controlling the vacuum level in the cavity. Please refer to Figure 2 In this embodiment, the four corners of the bottom of the upper mold body 5 are fixedly connected with insert rods 15, and the four corners of the top of the lower mold body 1 are provided with insertion holes 16, and the insert rods 15 are also inserted into the inside of the insertion holes 16. More specifically, by setting the insert rod 15 and the insertion hole 16, when the upper mold body 5 approaches the lower mold body 1, the insert rod 15 will be inserted into the insertion hole 16, so that the sliding of the insert rod 15 inside the insertion hole 16 will guide the mold closing position of the upper mold body 5 and prevent uncontrollable movement when the upper mold body 5 closes. Please refer to Figure 4 In this embodiment, a molding groove is provided at one end of the molding block 8 near the fixed mold insert B7, which is adapted to the edge contour of the outer sleeve of the motor housing end cover. When multiple molding blocks 8 are assembled together, a complete outer contour of the outer sleeve of the motor housing end cover is formed. In this embodiment, a gate is provided at the top of the upper mold body 5; Example 2: Please see Figure 2-4 This embodiment provides a technical solution based on embodiment one: the push component 4 includes: Support 9 is fixedly connected to the outside of the lower mold body 1. A cylinder 10 is fixedly connected to the end of support 9 away from the lower mold body 1. An assembly rod 11 is fixedly connected to the output end of cylinder 10. Assembly block 12 is slidably connected inside the lower cavity 2, and the end of assembly rod 11 away from cylinder 10 is also snapped to the corresponding assembly block 12. The top of assembly block 12 is fixedly connected to guide block 13, and four molding blocks 8 are snapped to one side of the four guide blocks 13 respectively. Please refer to Figure 3 In this embodiment, linear guide rails 17 are fixedly connected to all four ends of the lower cavity 2, and linear grooves are opened at the bottom ends of the four assembly blocks 12. The assembly blocks 12 are also slidably connected to the corresponding linear guide rails 17 through the linear grooves. More specifically, the linear guide 17 can effectively guide the displacement of the assembly block 12, preventing uncontrollable movement of the assembly block 12 and greatly ensuring the stability of the application of the assembly block 12. Please refer to Figure 3 In this embodiment, two limiting strips 18 are fixedly connected to each of the four ends of the lower cavity 2, and the two limiting strips 18 are located on both sides of the assembly block 12 respectively. More specifically, by setting the limit bar 18, the assembly block 12 can be limited, thereby guiding the displacement of the assembly block 12; Please refer to Figure 3 In this embodiment, an assembly groove is provided at one end of the assembly block 12 near the assembly rod 11. The assembly groove is T-shaped, and the assembly rod 11 is snapped into the inside of the assembly groove. More specifically, by setting the assembly slot, the assembly block 12 can have space to install the assembly rod 11. At the same time, in order to prevent the assembly rod 11 from detaching from the assembly block 12, a baffle is fixedly connected to the end of the assembly rod 11 away from the cylinder 10, and the diameter of the baffle is larger than the diameter of the assembly rod 11. Please refer to Figure 4 In this embodiment, a reference groove 19 is provided at one end of the molding block 8 near the guide block 13, and a stop protrusion is provided at one end of the guide block 13 near the reference groove 19, and the stop protrusion is also fixedly connected to the inside of the reference groove 19. More specifically, through the structural cooperation of the stop protrusion and the reference groove 19, before the molding block 8 and the guide block 13 are assembled, the stop protrusion is first moved into the reference groove 19. When the molding block 8 and the guide block 13 are in contact, the molding block 8 can be assembled in the designated position under the restriction of the stop protrusion, avoiding repeated adjustments.

[0017] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0018] During operation, the upper mold body 5 is first closed with the lower cavity 2 under the limiting position of the insertion rod 15 and the insertion hole 16. Then, the cylinder 10 is activated, and the assembly block 12 is adjusted under the guidance of the linear guide rail 17 with the help of the assembly rod 11. This causes multiple forming blocks 8 to move closer to each other until they are assembled, so that a complete motor housing end cover outer sleeve cavity is formed between the fixed mold insert A3, the fixed mold insert B7 and the forming blocks 8. Then, molten metal is injected into the cavity. After the molten metal cools down, the upper mold body 5 is removed from the lower mold body 1, and the cylinder 10 is activated to move the forming blocks 8 away from each other, thereby realizing the demolding of the motor housing end cover outer sleeve, which is more convenient for personnel to handle.
