[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a ring-shaped cutting edge design to remove the sprue, replacing the traditional sawing method. The cutting die is designed with ring-shaped distributed blades, and an inner circular insert is added to the upper die to support the product and prevent deformation when the blades cut the sprue, thus achieving the desired sprue removal effect. This significantly improves production efficiency, eliminates safety hazards, and overcomes the problems of existing methods for removing ring-shaped sprues from motor housings, which use a sawing machine, resulting in very slow efficiency, high cost, and safety risks.

[0016] By placing the motor housing that needs to have its sprue trimmed on top of the inner circular insert, the weight of the motor housing is detected by a pressure sensor. When the weight exceeds the specified weight of the motor housing, it indicates that there is excess sprue. At the same time, an alarm sounds, reminding the staff that the motor housing needs to have its sprue trimmed, thus achieving the purpose of intelligent detection of motor housing.

[0017] The suction plate is raised and lowered by a telescopic hydraulic cylinder, which is then attached to the upper part of the motor housing to position the motor housing. This improves the stability of the motor housing during the process of removing the sprue edge. The debris generated during the sprue edge removal falls into the sprue edge frame for collection. The debris can be melted and reused as raw material in the later stage, thus saving raw materials in the production of motor housing. Attached Figure Description

[0031] Working principle: The motor housing requiring sprue trimming is placed on the upper end of the inner circle insert 11. The weight of the motor housing is detected by the pressure sensor 24. When the weight exceeds the specified weight, it indicates the presence of excess sprue. Simultaneously, the alarm 3 sounds, reminding the operator that the motor housing needs sprue trimming. The inner circle insert 11 is used to fix the inner circle of the product and prevent deformation of the trimmed edges. Then, the telescopic hydraulic cylinder 8 drives the suction plate 9 to move up and down, causing the suction plate 9 to adhere to the upper position of the motor housing. The motor housing is positioned, and then the drive motor 6 is turned on. The drive motor 6 rotates and drives the transmission shaft 21 to rotate through the coupling 20. At the same time, the transmission shaft 21 rotates and drives the transmission gear 23 to rotate. The rotation of the transmission gear 23 drives the sleeve ring 17 that meshes with it to rotate, so that the six knife edge plates 15 and the inclined pressure plate 16 rotate. The knife edge plates 15 are used to cut the edges and remove the gate. The debris generated by cutting the edges falls into the cutting frame 2 for collection. Later, the debris can be melted and reused as raw material, thus completing the use of the motor housing gate cutting edge removal system.
