Description
Technical Field
[0001] This invention relates to the field of motor housing casting technology, specifically to a motor housing casting apparatus and casting method. Background Technology
[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes an energized coil (i.e., the stator winding) to generate a rotating magnetic field, which acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric torque. To enclose the rotor and stator components, a corresponding outer shell is needed. Existing shells are manufactured using a casting process, which requires casting equipment. However, existing casting equipment requires manual pouring of molten metal into a mold. After pouring, the product must be manually removed from the mold after cooling. During this process, workers are prone to burns due to the high temperature during pouring.

[0013] A casting method for an electric motor housing casting device, comprising the following steps: Step 1: Control the rotation motor to run through the controller. When the drive end of the rotation motor rotates, it drives the drive rod to rotate. The drive rod drives the drive gear to rotate. When the drive gear rotates, it drives the moving frame to move through the connecting rack. When the moving frame moves, it drives the lifting rod on the connecting slide rod to move downward through the connecting slide groove on the connecting top plate. This drives the moving mold core to move downward, so that the product is demolded from the moving mold core. When the moving frame moves, it drives the connecting plate and the limiting connecting seat to rotate around the center through the connecting connecting seat. This causes the two sets of moving outer molds to move in opposite directions on the connecting slide rail, so that the moving outer molds are separated. Step 2: Control the drive motor to run via the controller. When the drive motor rotates, it drives the drive rod to rotate, which in turn drives the drive helical gear to rotate. The drive helical gear drives the driven helical gear to rotate, which in turn drives the rotating rod to rotate. The rotating rod drives the rotating plate to rotate. When the rotating plate rotates, it drives the moving top plate and the moving slider to move on the moving slide rail via the rotating pull plate and the fixed connecting seat. When the moving top plate moves, it drives the moving top rod and the moving rack to move upward via the connecting slide rod under the action of the connecting slide groove. When the moving rack moves downward, it drives the rotating rod and the connecting plate to rotate via the rotating gear. When the connecting plate rotates, it drives the connecting shaft to move in the guide slide groove. When the connecting shaft moves in the guide slide groove, it drives the picking claw on the connecting slide to move to the right side. Under the action of the telescopic spring, when the connecting slide drives the picking claw to move downward, the product is clamped by the picking claw. Step 3: After the drive motor rotates continuously, it drives the drive rod to rotate, and the product is clamped off from the moving mold core. At this time, the controller controls the rotation motor to run. When the drive end of the rotation motor rotates, it drives the drive rod to rotate. The drive rod drives the drive gear to rotate. When the drive gear rotates, it drives the moving frame to move through the connecting rack. When the moving frame moves, it drives the lifting rod on the connecting slide rod to move upward through the connecting slide groove on the connecting top plate, thereby driving the moving mold core to move upward. When the moving frame moves, it drives the connecting plate and the limiting connecting seat to rotate around the center through the connecting connecting seat, so that the two sets of moving outer molds move in opposite directions on the connecting slide rail, so that the two sets of moving outer molds and the moving mold core are closed. Step 4: When the drive motor continues to rotate, it drives the drive rod to rotate. The drive rod drives the drive helical gear to rotate, which in turn drives the driven helical gear to rotate. The driven helical gear drives the rotating rod to rotate, which in turn drives the rotating plate to rotate. As the rotating plate rotates, it drives the moving top plate and the moving slider to move on the moving slide rail via the rotating pull plate and the fixed connecting seat. As the moving top plate moves, it drives the moving top rod and the moving rack to move upward via the connecting slide rod under the action of the connecting slide groove. As the moving rack moves downward, it drives the rotating rod and the connecting plate to rotate via the rotating gear. As the connecting plate rotates, it drives the connecting shaft to move in the guide slide groove. As the connecting shaft moves in the guide slide groove, it drives the connecting rotating shaft and the pouring ladle on the connecting slide to move above the mold pouring gate. As the connecting slide drives the connecting rotating shaft and the pouring ladle to move downward, under the action of the rotating plate and the guide inclined block, it drives the pouring ladle to rotate around the connecting rotating shaft as the axis, allowing the molten metal in the pouring ladle to be poured into the mold. Step 5: At this point, the product-holding gripper is moved to the left. Under the action of the conical top plate, as the connecting slide moves the product downward, the two sets of connecting slide plates are pushed open by the conical top plate, and the product falls off the gripper.
[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, by setting an automatic material handling structure in the motor housing casting device, the drive motor in the automatic material handling structure can automatically perform the product pouring and material handling work through the transmission structure, making the work easier for workers and reducing the probability of burns during work.
[0015] In this invention, by setting an automatic mold closing structure in the motor housing casting device, the rotating motor in the automatic mold closing structure can automatically perform mold closing and product demolding through the transmission structure, making the mold more synchronized during mold closing, thereby reducing the failure rate of the mold during mold closing. When demolding the product, the product can be quickly removed from the mold, improving the efficiency of product demolding.
[0016] In this invention, by setting an automatic material handling structure and an automatic mold closing structure in the motor housing casting device, the drive motor and rotation motor in the automatic material handling structure and the automatic mold closing structure can automatically carry out the entire process from product pouring, product molding and product unloading through the transmission structure, thereby improving the automation level of product manufacturing, greatly reducing labor costs, and also reducing the probability of worker injury during work.

[0021] The workflow of this invention is as follows: When using the motor housing casting device, the device is first connected to the power supply to put it into operation. The controller 4 controls the operation of the rotating motor 310. When the drive end of the rotating motor 310 rotates, it drives the drive rod 311 to rotate. The drive rod 311 drives the drive gear 312 to rotate. When the drive gear 312 rotates, it drives the moving frame 315 to move through the connecting rack 313. When the moving frame 315 moves, it drives the lifting rod 319 on the connecting slide rod 318 to move downward through the connecting slide groove 317 on the connecting top plate 316. This drives the moving mold core 307 to move downward, so that the product is demolded from the moving mold core 307. When the moving frame 315 moves, it drives the connecting plate 322 and the limiting connecting seat 323 to rotate around the center through the connecting connecting seat 321. This causes the two sets of moving outer molds 306 to move in opposite directions on the connecting slide rail 304, so that the moving outer molds 306 are separated. The controller 4 controls the operation of the drive motor 204. When the drive end of the drive motor 204 rotates, it drives the drive rod 205 to rotate. The drive rod 205 drives the drive helical gear 206 to rotate. The drive helical gear 206 drives the driven helical gear 207 to rotate. The driven helical gear 207 drives the rotating rod 208 to rotate. The rotating rod 208 drives the rotating plate 209 to rotate. When the rotating plate 209 rotates, it drives the moving top plate 212 and the moving slider 213 to move on the moving slide rail 214 through the rotating pull plate 210 and the fixed connecting seat 211. When the moving top plate 212 moves, it drives the moving top rod 217 and the moving rack 219 to move upward through the connecting slide rod 216 under the action of the connecting slide groove 215. When the moving rack 219 moves downward, it drives the rotating rod 222 and the connecting plate 223 to rotate via the rotating gear 221. When the connecting plate 223 rotates, it drives the connecting shaft 224 to move in the guide groove 225. When the connecting shaft 224 moves in the guide groove 225, it drives the picking claw 237 on the connecting slide 226 to move to the right side. Under the action of the telescopic spring 236, when the connecting slide 226 drives the picking claw 237 to move downward, the product is clamped by the picking claw 237. When the drive motor 204 rotates continuously, it drives the drive rod 205 to rotate, and the product is then clamped off from the moving mold core 307. At this time, the controller 4 controls the rotation motor 310 to run. When the drive end of the rotation motor 310 rotates, it drives the drive rod 311 to rotate. The drive rod 311 drives the drive gear 312 to rotate. When the drive gear 312 rotates, it drives the moving frame 315 to move through the connecting rack 313. When the moving frame 315 moves, it drives the lifting rod 319 on the connecting slide rod 318 to move upward through the connecting slide groove 317 on the connecting top plate 316, thereby driving the moving mold core 307 to move upward. When the movable frame 315 moves, the connecting plate 322 and the limiting connecting plate 323 rotate around the center through the connecting connecting seat 321, so that the two sets of movable outer molds 306 move in opposite directions on the connecting slide rail 304, so that the two sets of movable outer molds 306 and the movable mold core 307 are closed. When the drive motor 204 rotates continuously, it drives the drive rod 205 to rotate. The drive rod 205 drives the drive helical gear 206 to rotate. The drive helical gear 206 drives the driven helical gear 207 to rotate. The driven helical gear 207 drives the rotating rod 208 to rotate. The rotating rod 208 drives the rotating plate 209 to rotate. When the rotating plate 209 rotates, it drives the moving top plate 212 and the moving slider 213 to move on the moving slide rail 214 through the rotating pull plate 210 and the fixed connecting seat 211. When the moving top plate 212 moves, the moving top rod 217 and the moving rack 219 move upward through the connecting slide rod 216 under the action of the connecting slide groove 215. When the moving rack 219 moves downward, the rotating rod 222 and the connecting plate 223 rotate through the rotating gear 221. When the connecting plate 223 rotates, the connecting shaft 224 moves in the guide slide groove 225. When the connecting shaft 224 moves in the guide slide groove 225, it moves the connecting shaft 230 and the pouring ladle 231 on the connecting slide 226 to above the mold pouring gate. During the process of the connecting slide 226 moving the connecting shaft 230 and the pouring ladle 231 downward, the pouring ladle 231 rotates around the connecting shaft 230 as the axis under the action of the rotating plate 232 and the guide inclined block 233, so that the molten metal in the pouring ladle 231 is poured into the mold. At this time, the product-holding gripper 237 is moved to the left side. Under the action of the conical top plate 238, when the connecting slide bar 226 moves the product downward, the two sets of connecting slide plates 235 are pushed open by the conical top plate 238, and the product falls off the gripper 237.
