The motor is mainly composed of stator poles, rotor, brushes and housing. The front end cover of the motor is part of the housing. The front end cover of the motor is generally produced using a casting mold for the front end cover of the motor.

[0003] When using traditional casting molds, they can only be used to stamp and shape parts. After stamping and shaping, the parts will stick to the mold and cannot be removed, which not only affects the production efficiency of the company, but also workers may be injured due to improper operation or improper use of tools when demolding parts, such as pinching, scratching or impacting the hands. These injuries will not only affect the health and work efficiency of workers. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example: Refer to Figures 1 to 5 A casting mold for a front end cover of a motor comprises a base 1, and mounting holes 2 are provided at the four corners of the base 1. A bottom plate 3 is fixedly installed on the top of the base 1, and a stamping limit mechanism is arranged on the top of the bottom plate 3. A lower mold 4 is installed on the top of the bottom plate 3, and an upper mold 14 is arranged directly above the lower mold 4. The upper mold 14 is transmission-connected with the stamping limit mechanism, and a pressure ring 16 is fixedly connected to the bottom of the upper mold 14. A die groove 5 is provided on the top of the lower mold 4, and the pressure ring 16 is located directly above the die groove 5 and is adapted to the die groove 5, so that the material is conveniently stamped and plasticized by the stamping limit mechanism. A placement cavity 17 is provided inside the lower mold 4, and a demoulding mechanism is arranged on the top of the placement cavity 17; the upper mold 14 is driven by the stamping limit mechanism to stamp and shape the material on the lower mold 4, and then the front end shell formed in the die groove 5 is demoulded by the demoulding mechanism.

[0024] body, reference Figures 3 to 5 The demoulding mechanism includes a connecting plate 8, which is slidably installed inside the placement cavity 17. Two lower pressure columns 7 are fixedly connected to the top of the connecting plate 8. The two lower pressure columns 7 are arranged opposite to each other. The top of the lower pressure column 7 movably passes through the top of the lower mold 4. A plurality of ejector columns 6 are fixedly installed inside the connecting plate 8. The plurality of ejector columns 6 are all located inside the die groove 5. The tops of the plurality of ejector columns 6 movably pass through the top of the lower mold 4. A reset mechanism is provided at the bottom of the connecting plate 8, which drives the upper mold 14 to be pressed down through the stamping limit mechanism. The upper mold 14 first presses down the lower pressure column 7, and drives the connecting plate 8 to move downward, which has a certain force on the reset mechanism. When the material is stamped plastic, the reaction force of the reset mechanism drives the ejector column 6 and the lower pressure column 7 to move upward, and the ejector column 6 ejects the plasticized front end cover from the die groove 5 for demoulding.

[0025] Further, refer to Figure 4 and 5 The reset mechanism includes a plurality of limit columns 9, which are slidably connected to the connecting plate 8, and the bottom of the limit column 9 is fixedly connected to the inner wall of the lower mold 4. The outer wall of the limit column 9 is sleeved with a spring 10, and the bottom end of the spring 10 is fixedly connected to the inner wall of the lower mold 4. The top of the spring 10 is fixedly connected to the bottom of the connecting plate 8, driving the connecting plate 8 to move up and down on the limit column 9, which exerts a certain force on the spring 10, causing the spring 10 to deform and drive the top column 6 to move downward. Then, when the pressure ring 16 stamps the material into the die groove 5 for plasticity, the stamping limit mechanism moves upward, and the reaction force of the spring 10 causes the connecting plate 8 to reset.

[0026] Further, refer to Figure 1 and Figure 2 The stamping limiting mechanism includes a plurality of fixed columns 13, and the plurality of fixed columns 13 are respectively installed at the four corners of the bottom plate 3. A top plate 11 is fixedly installed on the top of the plurality of fixed columns 13, and a lower pressing plate 12 is arranged at the bottom of the top plate 11. The lower pressing plate 12 is slidably connected with the plurality of fixed columns 13, and the bottom of the lower pressing plate 12 is fixedly connected with the top of the upper mold 14. An electric push rod 15 is fixedly installed on the top of the top plate 11, and the output end of the electric push rod 15 passes through the top of the top plate 11 and is fixedly connected with the top of the lower pressing plate 12. Under the action of the electric push rod 15, the lower pressing plate 12 is driven to move downward, and at the same time, the fixed columns 13 are limited, which can ensure that the lower pressing plate 12 moves vertically downward, and ensures that the front end cover of the motor is stamped plastically under the cooperation of the pressure ring 16 and the die groove 5.

[0027] The working principle of the utility model is as follows:

[0028] The device is installed at a suitable position through the mounting hole 2 and the base 1, and the material to be stamped is placed above the die groove 5. Then, the electric push rod 15 is used to drive the lower pressure plate 12 to move downward, and then the upper mold 14 is driven downward, and the material is stamped plastically by the cooperation of the pressure ring 16 and the die groove 5. During the stamping process, the upper mold 14 first contacts the lower pressure column 7, and presses the lower pressure column 7 downward, which drives the connecting plate 8 to move downward. The connecting plate 8 has a certain downward pressure on the spring 10, which drives the ejector column 6 to move downward. When the stamping plasticity is completed, under the reaction force of the spring 10, the connecting plate 8 is driven to reset, and the lower pressure column 7 and the ejector column 6 are also driven to reset at the same time. Multiple ejector columns 6 push out the front end cover inside the die groove 5, which is convenient for demolding the front end cover.
