[0033] Please refer to Figures 1 to 4 This invention discloses a molding process for a motor end cover. The motor end cover 90 includes a base plate 91, a support base 92, a reinforcing base 93, a boss 94, a support platform 95, and a side plate 96. One end of the support base 92 protrudes from the base plate 91. The reinforcing base 93 protrudes from one side of the support base 92. The boss 94 protrudes from the end of the support base 92 away from the base plate 91. One end of the support platform 95 is connected to the boss 94, and the other end extends towards the base plate 91. One end of the side plate 96 is connected to the base plate 91, and the side plate 96 is arranged along the periphery of the base plate 91. Optionally, the base plate 91 has a through hole 911 and a strip hole 912; the support platform 95 has a through hole 951 in the middle. The molding process for the motor end cover includes the following steps: preliminary molding, boss 94 molding, reinforcing base 93 molding, and base plate 91 and side plate 96 molding. The end cover molding process of this motor first forms the support base 92 and the bearing platform 95 through preliminary molding, and then forms the boss 94, the reinforcing base 93, the base plate 91 and the side plate 96 in sequence to improve the processing accuracy; at the same time, each station processes synchronously to improve processing efficiency and reduce costs.

[0034] like Figures 2 to 4 As shown, in this embodiment, the motor end cover molding process includes the following steps:

[0035] Preliminary molding: A molding machine 100 is provided, including a base plate 10, a lower mold 20, a top plate 30, and an upper mold 40. There are multiple lower molds 20 and upper molds 40, and they correspond one-to-one. Each lower mold 20 and its corresponding upper mold 40 corresponds to a station. Each lower mold 20 is installed on the base plate 10, and each upper mold 40 is installed on the top plate 30. The flat metal part is placed in the molding station and molded into a support base 92 and a bearing platform 95 by the upper mold 40 and the lower mold 20.

[0036] Optionally, such as Figure 4 As shown, the preliminary forming step includes a support base 92 forming station and a support platform 95 forming station. When forming the support base 92, the upper mold 40 and the lower mold 20 cooperate to mold the flat metal part into a flat plate and a support base 92 protruding from the flat plate. When forming the support platform 95, the upper mold 40 and the lower mold 20 cooperate to recess the middle part of the support base 92 to form the support platform 95.

[0037] Furthermore, the forming station of the support platform 95 includes a preliminary forming station and a re-forming station. In the preliminary forming station, the upper mold 40 and the lower mold 20 work together to form the initial shape of the support base 92 and the support platform 95. In the re-forming station, the upper mold 40 and the lower mold 20 work together to form the precise shape of the support base 92 and the support platform 95. Through step-by-step multi-stage molding, the forming accuracy and quality are improved, and excessive deformation of the hardware parts caused by one-time molding is avoided, which could lead to the hardware parts bursting.

[0038] In one embodiment, the molding equipment 100 further includes a conveying assembly 50, which includes a first support plate 51, a first clamping block 52, a second support plate 53, and a second clamping block 54. The first support plate 51 and the second support plate 53 are respectively disposed on both sides of the substrate 10, and the first support plate 51 and the second support plate 53 can move synchronously along the extension direction of the substrate 10. There are multiple first clamping blocks 52 and second clamping blocks 54, and they correspond one-to-one. Each first clamping block 52 is installed on the first support plate 51, and each second clamping block 54 is installed on the second support plate 53. Each first clamping block 52 and the corresponding second clamping block 54 corresponds to a workstation, and the first clamping block 52 and the corresponding second clamping block 54 cooperate to clamp the hardware. With each synchronous movement of the first support plate 51 and the second support plate 53, the first clamping block 52 and the second clamping block 54 cooperate to convey the hardware to the next workstation, thereby realizing multi-station synchronous processing and improving production efficiency.

[0039] Boss 94 forming: The pre-formed hardware part is transferred to the forming station, where the boss 94 is formed by the upper mold 40 and the lower mold 20.

[0040] Reinforcing seat 93 forming: The hardware part with the already formed boss 94 is transferred to the forming station, and the reinforcing seat 93 is formed by molding with the upper mold 40 and the lower mold 20;

[0041] Forming of base plate 91 and side plate 96: The formed hardware is transferred to the forming station, where the base plate 91 and side plate 96 are formed by molding with upper mold 40 and lower mold 20. Optionally, before the forming step of base plate 91 and side plate 96, a trimming step is also included. The hardware with formed reinforcing seat 93 is transferred to the forming station, where the excess edge material on the flat plate is trimmed by molding with upper mold 40 and lower mold 20; then the trimmed hardware is transferred to the forming station, where the base plate 91 and side plate 96 are formed by molding with upper mold 40 and lower mold 20.

[0042] Furthermore, after the base plate 91 and side plate 96 are formed, the process also includes the step of stamping through holes 951 and through holes 911. The hardware of the formed base plate 91 and side plate 96 is transferred to the forming station and molded through holes by the upper mold 40 and the lower mold 20, so that the through hole 951 is formed in the middle of the support platform 95 and the through hole 911 is formed in the base plate 91.

[0043] After the step of stamping through holes 951 and through holes 911, the step of stamping strip holes 912 is also included. The hardware parts with stamped through holes 951 and through holes 911 are transferred to the forming station and molded through holes by the upper die 40 and the lower die 20, so that the base plate 91 forms strip holes 912.

[0044] After the stamping of the strip hole 912, there is also a deburring step, in which the metal part with the stamped strip hole 912 is transferred to the forming station and the burrs of the through hole 911 are removed by the upper die 40 and the lower die 20.

[0045] After the deburring step, a shaping step is also included, in which the deburred hardware parts are transferred to the forming station and molded by the upper mold 40 and the lower mold 20 to ensure dimensional accuracy.

[0046] The end cover molding process of this motor improves processing accuracy and quality through step-by-step processing. Moreover, through the synchronous movement of the first support plate 51 and the second support plate 53, the first clamping block 52 and the second clamping block 54 cooperate to transfer the hardware to the next station, realizing synchronous processing at each station and improving processing efficiency.

[0047] The motor end cover molding process of the present invention forms a support base 92 and a bearing platform 95 through preliminary molding, and then forms a boss 94, a reinforcing base 93, a bottom plate 91 and a side plate 96 in sequence, thereby improving the processing accuracy; at the same time, each station processes synchronously, thereby improving processing efficiency and reducing costs.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
