The motor is then controlled by the software control algorithm. A resolver is mainly composed of a resolver stator and a resolver rotor. The resolver stator consists of a stator core, a stator winding that generates signals and an excitation winding.

[0003] Patent No. CN201910805530.6 proposes an integrated molding process for rotary transformers and its injection mold. By integrally injection molding the stator frame assembly, housing, inserts, mounting holes, and connectors, the number of assembly parts and steps can be reduced, the accumulation of installation dimensional tolerances can be reduced, and the product accuracy can be improved. At the same time, the overall strength of the rotary transformer is improved, and the accuracy and stability of the rotary transformer are improved simultaneously. However, this patent cannot be adjusted according to the thickness of a single iron core. Different iron cores require different molds.

[0016] To better achieve the objectives of this invention, the present invention also provides a method for using a rotary stator mold and forming equipment compatible with cores of different thicknesses, comprising the following steps:

[0017] Step 1: The drive motor of the mold adjustment device rotates, which drives the worm gear to rotate. The worm gear rotates, which drives the worm wheel to rotate. The worm wheel rotates, which drives the threaded slider to rotate. The threaded slider rotates, which drives the threaded rod to move up and down. The threaded rod moves up and down, which drives the sliding outer mold to move up and down to adapt to iron cores of different thicknesses.

[0018] Step 2: Start the cylinder. The cylinder output end moves upward, causing the mold support frame to move upward. The mold support frame moves upward, causing the upper mold to move upward. The mold support frame moves upward, causing the right end of the lever to move upward. The left end of the lever moves downward, causing the rotating cylinder to move downward. The rotating cylinder moves downward, causing the rotating cylinder to rotate 60 degrees. The rotating cylinder rotates 60 degrees, causing the hexagonal rotating frame to rotate 60 degrees. The hexagonal rotating frame rotates 60 degrees, causing the extension bracket to rotate 60 degrees. The electromagnet that attracts the iron core rotates to the top of the sliding outer mold. At this time, the button switch touches the first lever, causing the electromagnet to turn off, and the iron core falls onto the sliding outer mold.

[0019] Step 3: The cylinder output end moves down, causing the mold support frame to move down. The mold support frame moves down, causing the upper mold to move down. Molding is injected through the injection port inside the upper mold. The mold support frame moves down, causing the right end of the lever to move down. The left end of the lever moves up, causing the rotating cylinder to move up. The rotating cylinder moves up, causing the rotating cylinder to rotate 60 degrees. The rotating cylinder rotates 60 degrees, causing the hexagonal rotating frame to rotate 60 degrees. The hexagonal rotating frame rotates 60 degrees, causing the extension bracket to rotate 60 degrees. The electromagnet rotates to the top of the sliding outer mold side.

[0020] Step 4: The cylinder output end moves upward. At this time, the extension bracket with cooling fan moves to the upper side of the sliding outer mold. Press and hold the switch to contact the first lever to turn on the cooling fan and quickly cool and solidify the injection-molded product.

[0021] Step 5: The cylinder output end moves down, the upper mold moves down to perform secondary shaping of the cooled product, the chain lifting machine starts and stops at regular intervals to transport the iron core to the top of the fixed tube, at this time one of the extension brackets with electromagnet moves to the top of the fixed tube, the button switch touches the second lever, causing the closed electromagnet to open and attract the iron core on the fixed tube.

[0022] Step Six: The cylinder output end moves upward, the upper mold moves upward, and at this time, the other extension bracket with electromagnet moves to the upper side of the sliding outer mold. The button switch touches the first lever to open the electromagnet, and the electromagnet attracts the injection-molded product.

[0023] Step 7: The cylinder output end moves down, the electromagnet adsorbing the product moves to the position of the stop bar, the cylinder output end moves up, the upper mold moves up, the electromagnet adsorbing the iron core moves to the upper side of the sliding outer mold, at this time the button switch touches the first lever to turn off the electromagnet, the iron core falls into the sliding outer mold, the electromagnet adsorbing the product passes through the stop bar, the stop bar stops the product and falls into the conveyor belt.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This invention utilizes a drive motor to rotate a worm gear, which in turn rotates a worm wheel, which in turn rotates a threaded slider. This allows the sliding outer mold to be finely adjusted up and down to accommodate iron cores of different thicknesses. The sliding outer mold moves a side extension rod, which, in conjunction with a scale bar, allows observation of the adjustment range, facilitating control over the height changes of the sliding outer mold. An upward movement of the cylinder moves the mold support frame upward, which in turn moves the upper mold upward. This upward movement of the mold support frame moves the right end of the lever upward, while the left end of the lever moves downward, causing the rotating cylinder to move downward. This downward movement of the rotating cylinder causes the rotating cylinder to rotate 60 degrees. Thus, each movement of the cylinder output end causes the hexagonal rotating frame to rotate 60 degrees, and each up-and-down movement of the cylinder output end causes the hexagonal rotating frame to rotate 120 degrees. Simultaneous mechanical loading and unloading allows for secondary cooling and shaping of the injection-molded product, shortening the time required. The intermittent lifting of the chain lifting mechanism in the material lifting device allows for intermittent feeding of the iron core onto the fixed tube, improving production efficiency.

6. A method of using the molding equipment as described in claim 5, characterized in that, Includes the following steps: Step 1: The drive motor of the mold adjustment device rotates, which drives the worm gear to rotate. The worm gear rotates, which drives the worm wheel to rotate. The worm wheel rotates, which drives the threaded slider to rotate. The threaded slider rotates, which drives the threaded rod to move up and down. The threaded rod moves up and down, which drives the sliding outer mold to move up and down to adapt to iron cores of different thicknesses. Step 2: Start the cylinder. The cylinder output end moves upward, causing the mold support frame to move upward. The mold support frame moves upward, causing the upper mold to move upward. The mold support frame moves upward, causing the right end of the lever to move upward. The left end of the lever moves downward, causing the rotating cylinder to move downward. The rotating cylinder moves downward, causing the rotating cylinder to rotate 60 degrees. The rotating cylinder rotates 60 degrees, causing the hexagonal rotating frame to rotate 60 degrees. The hexagonal rotating frame rotates 60 degrees, causing the extension bracket to rotate 60 degrees. The electromagnet that attracts the iron core rotates to the top of the sliding outer mold. At this time, the button switch touches the first lever, causing the electromagnet to turn off, and the iron core falls onto the sliding outer mold. Step 3: The cylinder output end moves down, causing the mold support frame to move down. The mold support frame moves down, causing the upper mold to move down. Molding is injected through the injection port inside the upper mold. The mold support frame moves down, causing the right end of the lever to move down. The left end of the lever moves up, causing the rotating cylinder to move up. The rotating cylinder moves up, causing the rotating cylinder to rotate 60 degrees. The rotating cylinder rotates 60 degrees, causing the hexagonal rotating frame to rotate 60 degrees. The hexagonal rotating frame rotates 60 degrees, causing the extension bracket to rotate 60 degrees. The electromagnet rotates to the top of the sliding outer mold side. Step 4: The cylinder output end moves upward. At this time, the extension bracket with cooling fan moves to the upper side of the sliding outer mold. Press and hold the switch to contact the first lever to turn on the cooling fan and quickly cool and solidify the injection-molded product. Step 5: The cylinder output end moves down, the upper mold moves down to perform secondary shaping of the cooled product, the chain lifting machine starts and stops at regular intervals to transport the iron core to the top of the fixed tube, at this time one of the extension brackets with electromagnet moves to the top of the fixed tube, the button switch touches the second lever, causing the closed electromagnet to open and attract the iron core on the fixed tube. Step Six: The cylinder output end moves upward, the upper mold moves upward, and at this time, the other extension bracket with electromagnet moves to the upper side of the sliding outer mold. The button switch touches the first lever to open the electromagnet, and the electromagnet attracts the injection-molded product. Step 7: The cylinder output end moves down, the electromagnet adsorbing the product moves to the position of the stop bar, the cylinder output end moves up, the upper mold moves up, the electromagnet adsorbing the iron core moves to the upper side of the sliding outer mold, at this time the button switch touches the first lever to turn off the electromagnet, the iron core falls into the sliding outer mold, the electromagnet adsorbing the product passes through the stop bar, the stop bar stops the product and falls into the conveyor belt.
