[0044] like Fig.16 As shown, the feeding assembly includes a servo motor 501 and a screw rod 502. The screw rod 502 is rotatably connected to the discharge barrel 104. The servo motor 501 is installed on the rear side of the discharge barrel 104 by bolts. The output shaft of the servo motor 501 passes through the discharge barrel 104 and is connected to the screw rod 502. The servo motor 501 is electrically connected to the controller 102.

[0045] like Figure 6-Figure 8 and Figure 10-11As shown, the centering component includes a centering block 302, a return spring 303, a connecting block 304 and a reference block 305. The centering block 302 is slidably connected to the upper side of the pushing frame 301, and the return spring 303 is connected between the centering block 302 and the pushing frame 301. The connecting blocks 304 are connected to the positions aligned with the injection cavity on the rear side wall of the mold 108, and the reference blocks 305 are symmetrically integrally formed on the upper sides of the connecting blocks 304. The centering block 302 can move downward to contact the two reference blocks 305 on the same side, thereby correcting the position of the mold 108 in the center.

[0046] When performing injection molding of the ceramic core, the mixed raw materials are added into the material barrel 103, and the raw materials will fall downward into the discharge barrel 104, and then contact the screw rod 502. The staff installs the mold 108 on the movable frame 201, and then operates the controller 102 to start the electric slide rail 105a. The electric slide rail 105a will drive the sliding frame 105b and the connecting head 105c to move downward, and then pull the injection head 107 and the telescopic tube 106 to move downward. The telescopic tube 106 will extend, and the sliding frame 105b will move downward to drive the push frame 301 and the center block 302 to move downward. The center block 302 will contact the two reference blocks 305 on the same side, move downward along the reference block 305, and then correct the position of the reference block 305, such as the mold 108 position. If the position is not accurate enough, the centering block 302 will move the two reference blocks 305 to correct the position of the mold 108 and the moving frame 201, so that the injection cavity on the mold 108 is aligned with the injection head 107. The downward movement of the pushing frame 301 also drives the pushing block 203 to move downward. When the pushing block 203 contacts the inclined rod 202, it will be blocked by the inclined rod 202, so that the pushing block 203 and the blocking bar 205 rotate upward, and the torsion spring 1 204 is deformed, and the pushing block 203 can continue to move downward and pass over the inclined rod 202. When the pushing block 203 is not blocked, it will reverse and reset under the reset action of the torsion spring 1 204, and the injection head 107 will move downward to engage with the injection cavity, and the mold 108 will resist the injection head 107. The connecting head 105c continues to move downward, which will compress the compression spring 109. , the connector 105c will no longer block the discharge port 1010 on the injection head 107, the controller 102 is operated to start the servo motor 501, the output shaft of the servo motor 501 rotates to drive the screw rod 502 to rotate, the screw rod 502 pushes the raw material, so that the raw material is extruded from the injection head 107 into the injection cavity through the telescopic tube 106, after the raw material is loaded, the servo motor 501 is paused to stop the screw rod 502 from conveying the raw material, the electric slide rail 105a is operated to drive the sliding frame 105b and the connector 105c to move upward, the connector 105c drives the injection head 107 and the telescopic tube 106 to move upward, the compression spring 109 rebounds and resets, the connector 105c will rebound to block the discharge port 1010, so that the raw material no longer flows out, on the sliding frame 105b When the push block 203 moves upward, it will also drive the pushing frame 301, the centering block 302, the pushing block 203 and the blocking bar 205 to move upward. The pushing block 203 moves upward and is blocked by the inclined rod 202. Under the action of the blocking bar 205, the pushing block 203 will not be pushed by the inclined rod 202 to rotate downward. The pushing block 203 continues to move upward and will push the inclined rod 202 to move to the right, thereby driving the moving frame 201 and the mold 108 to move to the right. If the centering block 302 moves upward and collides with the reference block 305, the return spring 303 will play a buffering role, so that the centering block 302 moves backward and passes over the reference block 305. After the pushing block 203 moves upward and passes over the inclined rod 202, the inclined rod 202 stops moving. Under the action of the inclined rod 202, the moving frame 201 moves to the right with the mold 108.The next injection cavity will be aligned with the injection head 107. After the electric slide rail 105a drives the sliding frame 105b to move up and reset, it will automatically pause, so that the mold 108 can be automatically pushed. There is no need to manually adjust the position of the mold 108, and the injection work can be carried out uninterruptedly. Repeat the above operation to continue to load the remaining injection cavities on the mold 108. Finally, when all the injection cavities on the mold 108 are loaded, the mold 108 is removed from the mobile frame 201, and a new mold 108 is replaced on the mobile frame 201, and the mobile frame 201 is pushed to the left to reset to the initial position.

[0047] Embodiment 2: Based on embodiment 1, Figure 15-16 As shown, the injection feeder also includes a driving motor 401, a transmission assembly 402, a stirring frame 403 and a scraper rod 404. The transmission assembly 402 is installed on the top of the barrel 103. The transmission assembly 402 is a prior art and transmits power through a conveyor belt. The driving motor 401 is installed on the top of the transmission assembly 402 by bolts. The driving motor 401 is electrically connected to the controller 102. The driving motor 401 is connected to the rotating shaft on the transmission assembly 402. The barrel 103 is rotatably connected with a stirring frame 403 for stirring raw materials. The upper end of the stirring frame 403 is connected to another rotating shaft on the transmission assembly 402. A plurality of scraper rods 404 are welded to the outer side of the stirring frame 403 at intervals along the circumferential direction, and the scraper rods 404 are close to the inner wall of the barrel 103.

[0048] After the raw materials are added into the barrel 103, during the injection molding process of the ceramic core, the controller 102 can be operated to start the drive motor 401. The rotation of the output shaft of the drive motor 401 will drive the stirring frame 403 and the scraper rod 404 to rotate. The raw materials are mixed by the stirring frame 403 to improve the uniformity of the raw materials, and the scraper rod 404 can scrape off the raw materials stuck to the inner wall of the barrel 103 to ensure that the raw materials can be evenly delivered into the discharge barrel 104. After finishing the work, the drive motor 401 can be turned off.

[0049] like Figure 1 and Figure 17-Figure 20As shown, the injection feeding machine also includes a support plate 601, a tension spring 602, a spur gear 603, a ratchet gear 604, a lever 605, a rack 606, a torsion spring 607 and an electric push rod 608. The front side of the base frame 1 is slidably connected to the support plate 601, two tension springs 602 are connected between the left end of the mold 108 and the base frame 1, and a plurality of ratchet gears 604 are evenly spaced and rotatably connected to the top of the support plate 601. The tops of the ratchet gears 604 are all connected to the spur gears 603 by bolts. The support plate 601 The top position located in front of the ratchet gear 604 is rotatably connected with a lever 605, and the lever 605 is snap-fitted with the ratchet gear 604 on the same side. A torsion spring 607 is connected between the lever 605 and the support plate 601. A rack 606 is welded on the front side of the movable frame 201, and the rack 606 is meshed with the spur gear 603. A plurality of electric push rods 608 are evenly installed on the bottom of the base frame 1 through bolts. The telescopic rods of the electric push rods 608 are all connected to the support plate 601, and the electric push rods 608 are electrically connected to the controller 102.

[0050] When the inclined rod 202 drives the movable frame 201 and the mold 108 to move to the right side for injection molding of the ceramic core, the rack 606 will move along, the movable frame 201 moves to the right side, the tension spring 602 will be stretched, the rack 606 moves to the right side, which will drive the spur gear 603 to rotate counterclockwise, and then drive the ratchet gear 604 to rotate, the lever 605 will be pushed outward by the ratchet gear 604, the torsion spring 607 will be deformed, and the ratchet gear 604 will rotate counterclockwise to pass the lever 605. If the movable frame 201 is unstable and moves backward, the lever 605 will jam the ratchet gear 604, so that the ratchet gear 604 cannot rotate clockwise, so that the movable frame 201 is fixed and cannot move backward to the left, ensuring that the movable frame 201 position accuracy. When the injection molding cavities on the mold 108 are all loaded with materials, the controller 102 can be operated to start the electric push rod 608. The extension of the telescopic rod of the electric push rod 608 will drive the support plate 601 to move forward, and then drive the spur gear 603, the ratchet gear 604, and the lever 605 to move forward, so that the spur gear 603 and the rack 606 are disengaged. The movable frame 201 will move to the left and reset under the reset action of the tension spring 602, and move the mold 108 and the inclined rod 202 to the left, so as to realize the automatic reset of the movable frame 201. After resetting, the telescopic rod of the electric push rod 608 is controlled to shorten and reset, and the spur gear 603, the ratchet gear 604, and the lever 605 are driven to move backward and reset.

[0051] like Figure 1 and Figure 21-22 As shown, the injection feeder also includes a fixing seat 701 and a cleaning block 702. The top of the base frame 1 located on the right side of the support seat 101 is connected to the fixing seat 701 by bolts, and the cleaning block 702 is connected to the front side of the fixing seat 701. A waste slot 703 is opened in the cleaning block 702.

[0052] When the mold 108 moves to the right, it will contact the bottom surface of the cleaning block 702. The cleaning block 702 will scrape the waste remaining at the upper end of the injection cavity into the waste groove 703 to avoid affecting the connection between the injection head 107 and the injection cavity. The waste in the waste groove 703 can be cleaned later.
