[0011] The method for using the fire pump casting mold includes the following steps: S1. With the start-up of the device, the transmission motor rotates counterclockwise, the motor main shaft drives the power block to rotate, the power rod pulls the connection block to rotate on the connection plate through the spring telescopic rod on the outer wall, and at the same time, the connection plate is pushed to slide on the vertical rod, and the vertical rod slides on the guide column through the moving block. At this time, the movable frame is driven to move toward the bottom mold through the connecting plate. Since the movable frame is sleeved on the top mold, the top mold moves forward with the movable frame. At this time, the top mold is placed on the top of the bottom mold. Due to the inner groove setting on the bottom mold, the bottom end of the top mold is inserted into the inner groove to connect the top mold and the bottom mold; S2. Immediately thereafter, the movable frame continues to move downward, the bottom end of the movable frame pushes the pressing block, the pressing block presses down to squeeze the plug sleeve, the plug sleeve squeezes the tilting rod to slide to the left, at this time, the hinged rods at the front and rear ends of the tilting rod will move synchronously to pull and push the left and right plates to drive the bottom plate to slide to the left, because the bottom plate and the top plate are connected by a hinged tilting plate, the bottom plate moves to the left, and the tilting plate is tilted to the right. Since the tilting plate is slidably connected to the bottom wall of the top plate, the tilting plate moves downward, driving several spring rods to be retracted into the bottom mold, and the mold is completed at this time, and the staff can pour through the feed port for casting; S3. After the casting is completed, the movable frame is controlled to rise again. The movable frame continues to rise. The movable frame releases the extrusion state before the pressing block. At this time, when the pressing block moves downward, the inner column will rise, and the strong springs on the pressing block and the inner column are in a compressed state. When the pressing block is no longer affected by external force, the strong spring resets, the bottom plate resets, and the top plate is pushed continuously by the inclined plate to remove the mold; S4. Then, as the movable frame continues to rise, due to the unevenness of the deep groove and the matching setting of the friction block, the movable frame can drive the top mold to continue to rise until it contacts the top wall of the auxiliary frame. At this time, the friction block on the movable frame cannot continue to drive the top mold to rise. The friction block slides in the deep groove through the setting of the spring. At this time, due to the independent rise of the movable frame, the movable frame pulls the outer tooth plate upward through the connecting plate on one side. Since the outer tooth plate and the inner tooth plate are meshed with the same transmission gear, the upper surface of the outer tooth plate The lifting can push the inner tooth plate to slide downward through the transmission gear. At this time, the inner tooth plate pushes down the sliding seat. Since the sliding seat is provided with a V-shaped groove and a W-shaped groove, when the sliding seat moves downward, the limit rod in the sliding seat contacts the top of the V-shaped groove, and the limit rod is squeezed to deflect to the left. The limit rod slides from the V-shaped groove into the W-shaped groove. At this time, the sliding seat moves downward, and the sliding seat pushes the connecting seat to rotate toward the bottom mold through the arc rod. Since the top mold and the bottom mold are in separate rotation at this time, the clamping head can clamp the object in the bottom mold. S5. Finally, after completing the material clamping, control the transmission motor to rotate in the opposite direction, and the connecting plate can drive the movable frame to move to the right. At this time, the top mold and the object move toward the right side of the auxiliary frame until the movable frame completes the movement of the inverted L-shaped trajectory. At this time, the object contacts the bottom wall of the cleaning tank on the auxiliary frame, and the top mold is also buckled on the object. At the same time, the movable frame moves down, the outer tooth plate is squeezed down, and the inner tooth plate is reset. At this time, the sliding seat is reset by the spring, and the convex point on the limit rod is stuck in the inside of the W-shaped groove. At the same time, the bottom end of the extrusion plate on the limit rod will contact the limit block. Since the bottom end of the extrusion plate is provided with an inclined surface, the extrusion plate is pressed to move to the left, and the extrusion plate pushes the inner plate. The inner plate and the convex point are retracted toward the inside of the limit rod together. At this time, the sliding seat loses the restriction of the convex point, and the sliding seat is reset by the spring. The sliding seat drives the clamping head to reset and releases the object. Then the transmission motor is controlled to rotate counterclockwise again to perform the casting process reciprocatingly.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, through the arrangement of the outer tooth plate, the inner tooth plate and the clamping head, when the upper and lower molds are opened, the clamping head can be triggered to clamp the surface of the finished object, so that the finished object is fixedly clamped until the object is placed outside the bottom mold, making it convenient for the staff to pick up the object.

[0013] In the present invention, by setting the V-shaped groove and the W-shaped groove, the position of the sliding seat can be locked when the clamping head changes, which is convenient for continuous clamping of objects and quick release of the clamping of objects, and is convenient for use by staff.

[0014] In the present invention, by providing the ejector and the guide column, the movable frame can follow an N-shaped structure route, making it convenient to take objects, and when the movable frame drives the upper and lower molds to separate, the objects can be ejected quickly.

When the pressure block 587 moves downward, the inner column 582 rises, and the strong springs on the pressure block 587 and the inner column 582 are in a compressed state, so that when the pressure block 587 is no longer affected by external force, the strong spring resets, the bottom plate 55 resets, and the top plate 52 is continuously pushed upward by the inclined plate 54 to perform demolding.

[0025] In this embodiment, Figures 1 to 5 As shown, the method for using the fire pump casting mold includes the following steps: S1. With the start-up of the device, the transmission motor rotates counterclockwise, and the motor main shaft drives the power block 421 to rotate. The power rod pulls the connecting block 419 through the spring telescopic rod 420 on the outer wall to rotate on the connecting plate 44, and at the same time, the connecting plate 44 is pushed to slide on the vertical rod 417, and the vertical rod 417 slides on the guide column 415 through the moving block 416. At this time, the movable frame 41 is driven to move toward the bottom mold 2 through the connecting plate 44. Since the movable frame 41 is sleeved on the top mold 3, the top mold 3 moves forward with the movable frame 41. At this time, the top mold 3 is placed on the top of the bottom mold 2. Due to the inner groove setting on the bottom mold 2, the bottom end of the top mold 3 is inserted into the inner groove to connect the top mold 3 and the bottom mold 2; S2. Following the continuous downward movement of the movable frame 41, the bottom end of the movable frame 41 pushes the pressing block 587, and the pressing block 587 presses down and squeezes the plug sleeve 584, and the plug sleeve 584 squeezes the tilting rod 583 to slide to the left. At this time, the hinged rods 586 at the front and rear ends of the tilting rod 583 will move synchronously to pull and push the left plate 56 and the right plate 57 to drive the bottom plate 55 to slide to the left. Since the bottom plate 55 and the top plate 52 are connected by the hinged tilting plate 54, the bottom plate 55 moves to the left, and the tilting plate 54 is tilted to the right. Since the tilting plate 54 is slidably connected to the bottom wall of the top plate 52, the tilting plate 54 moves downward, driving a number of spring rods 53 to be retracted into the bottom mold 2. At this time, the mold is completed, and the staff can pour through the feed port for casting; S3, after the casting is completed, the movable frame 41 is controlled to rise again, and the movable frame 41 continues to rise. The movable frame 41 is released from the extrusion state before the pressing block 587. At this time, when the pressing block 587 moves downward, the inner column 582 will rise, and the strong springs on the pressing block 587 and the inner column 582 are in a compressed state, so that when the pressing block 587 is no longer affected by external force, the strong spring is reset, the bottom plate 55 is reset, and the top plate 52 is continuously pushed upward by the inclined plate 54 to remove the mold; S4. Then, with the continuous rise of the movable frame 41, due to the unevenness of the deep groove and the matching setting of the friction block, the movable frame 41 can drive the top mold 3 to continue to rise until it contacts the top wall of the auxiliary frame 1. At this time, the friction block on the movable frame 41 cannot continue to drive the top mold 3 to rise. The friction block slides in the deep groove through the setting of the spring. At this time, due to the independent rise of the movable frame 41, the movable frame 41 pulls the outer tooth plate 45 upward through the connecting plate 44 on one side. Since the same transmission gear 47 is engaged between the outer tooth plate 45 and the inner tooth plate 48, the rise of the outer tooth plate 45 can push the inner tooth plate through the transmission gear 47. 48 slides downward, at this time the inner tooth plate 48 pushes down the sliding seat 49, since the sliding seat 49 is provided with a V-shaped groove 411 and a W-shaped groove 412, when the sliding seat 49 moves downward, the limiting rod 410 in the sliding seat 49 contacts with the top end of the V-shaped groove 411, squeezing the limiting rod 410 to deflect to the left, and the limiting rod 410 slides from the V-shaped groove 411 into the W-shaped groove 412, at this time the sliding seat 49 moves downward, and the sliding seat 49 pushes the connecting seat 4143 to rotate toward the bottom mold 2 through the arc rod 4142, and since the top mold 3 and the bottom mold 2 are in a separated rotation at this time, the clamping head 414 can clamp the object in the bottom mold 2; S5. Finally, after the material is clamped, the transmission motor is controlled to rotate in the opposite direction, and the connecting plate 44 can drive the movable frame 41 to move to the right. At this time, the top mold 3 and the object move to the right side of the auxiliary frame 1 until the movable frame 41 completes the movement of the inverted L-shaped trajectory. At this time, the object contacts the bottom wall of the cleaning tank on the auxiliary frame 1, and the top mold 3 is also buckled on the object. At the same time, the movable frame 41 moves down, squeezing the outer tooth plate 45 to move down, and the inner tooth plate 48 is reset. At this time, the sliding seat 49 is reset by the spring, and the convex point on the limit rod 410 is stuck in the inner wall of the W-shaped groove 412. At the same time, the bottom end of the extrusion plate 423 on the limit rod 410 will contact the limit block 424. Since the bottom end of the extrusion plate 423 is provided with an inclined surface, the extrusion plate 423 is pressed to move to the left, and the extrusion plate 423 pushes the inner plate 422. The inner plate 422 and the protrusion are retracted into the inside of the limit rod 410. At this time, the sliding seat 49 loses the restriction of the protrusion, and the sliding seat 49 is reset by the spring. The sliding seat 49 drives the clamping head 414 to reset and release the object. Then the transmission motor is controlled to rotate counterclockwise again, and the casting process is repeated.

8. A method for using a fire pump casting mold, using the fire pump casting mold as claimed in any one of claims 1 to 7, characterized in that: The steps include: S1. With the start-up of the device, the transmission motor rotates counterclockwise, the motor main shaft drives the power block (421) to rotate, the power rod pulls the connecting block (419) to rotate on the connecting plate (44) through the spring telescopic rod (420) on the outer wall, and at the same time, the connecting plate (44) is moved to slide on the vertical rod (417), and the vertical rod (417) slides on the guide column (415) through the moving block (416). At this time, the movable frame (41) is driven to move toward the bottom mold (2) through the connecting plate (44). Since the movable frame (41) is sleeved on the top mold (3), the top mold (3) moves forward with the movable frame (41). At this time, the top mold (3) is placed on the top of the bottom mold (2). Due to the inner groove setting on the bottom mold (2), the bottom end of the top mold (3) is inserted into the inner groove to connect the top mold (3) and the bottom mold (2); S2, immediately after the movable frame (41) continues to move downward, the bottom end of the movable frame (41) pushes the pressing block (587), the pressing block (587) presses down the plug sleeve (584), the plug sleeve (584) squeezes the tilting rod (583) to slide to the left, at this time, the hinged rods (586) at the front and rear ends of the tilting rod (583) will move synchronously to pull and push the left plate (56) and the right plate (57) to drive the bottom plate (55) to slide to the left, because the bottom plate (55) and the top plate (52) are connected by the hinged tilting plate (54), the bottom plate (55) moves to the left, and the tilting plate (54) is tilted to the right. Since the tilting plate (54) is slidably connected to the bottom wall of the top plate (52), the tilting plate (54) moves downward, driving a plurality of spring rods (53) to be received in the bottom mold (2), and the mold is completed at this time, and the staff can pour through the feed port to perform casting; S3, after the casting is completed, the movable frame (41) is controlled to rise again, and the movable frame (41) continues to rise. The movable frame (41) is released from the extrusion state before the pressing block (587). At this time, when the pressing block (587) moves downward, the inner column (582) will rise, and the strong springs on the pressing block (587) and the inner column (582) are in a compressed state, so that when the pressing block (587) is no longer affected by external force, the strong spring is reset, the bottom plate (55) is reset, and the top plate (52) is continuously pushed upward by the inclined plate (54) to perform demoulding; S4. Then, as the movable frame (41) continues to rise, due to the unevenness of the deep groove and the matching arrangement of the friction block, the movable frame (41) can drive the top mold (3) to continue to rise until it contacts the top wall of the auxiliary frame (1). At this time, the friction block on the movable frame (41) cannot continue to drive the top mold (3) to rise. The friction block slides in the deep groove through the arrangement of the spring. At this time, due to the independent rise of the movable frame (41), the movable frame (41) pulls the outer tooth plate (45) upward through the connecting plate (44) on one side. Since the outer tooth plate (45) and the inner tooth plate (48) are meshed with the same transmission gear (47), the rise of the outer tooth plate (45) can push the inner tooth plate (48) to slide downward through the transmission gear (47). At this time, the inner tooth plate (48) pushes the sliding seat (49) downward. Since the sliding seat (49) is provided with a V-shaped groove (411) and a W-shaped groove (412), when the sliding seat (49) moves downward, the limiting rod (410) in the sliding seat (49) contacts the top of the V-shaped groove (411), squeezing the limiting rod (410) to deflect to the left, and the limiting rod (410) slides from the V-shaped groove (411) into the W-shaped groove (412). At this time, the sliding seat (49) moves downward, and the sliding seat (49) pushes the connecting seat (4143) to rotate toward the bottom mold (2) through the arc rod (4142). Since the top mold (3) and the bottom mold (2) are in a separated rotation at this time, the clamping head (414) can clamp the object in the bottom mold (2); S5. Finally, after the material is clamped, the transmission motor is controlled to rotate in the opposite direction, and the connecting plate (44) can drive the movable frame (41) to move to the right. At this time, the top mold (3) and the object move toward the right side of the auxiliary frame (1) until the movable frame (41) completes the movement of the inverted L-shaped trajectory. At this time, the object contacts the bottom wall of the cleaning tank on the auxiliary frame (1), and the top mold (3) is also buckled on the object. At the same time, the movable frame (41) moves downward, pressing the outer tooth plate (45) to move downward, and the inner tooth plate (48) is reset. At this time, the sliding seat (49) is reset by the spring, and the convex point on the limit rod (410) is stuck in the inner part of the W-shaped groove (412). At the same time, the bottom end of the extrusion plate (423) on the limit rod (410) contacts the limit block (424). Since the bottom end of the extrusion plate (423) is provided with an inclined surface, the extrusion plate (423) is pressed to move to the left, and the extrusion plate (423) pushes the inner plate (422). The inner plate (422) and the protrusion are retracted into the inside of the limit rod (410). At this time, the sliding seat (49) loses the restriction of the protrusion, and the sliding seat (49) is reset by the spring. The sliding seat (49) drives the clamping head (414) to reset and release the object. Then, the transmission motor is controlled to rotate counterclockwise again, and the casting process is repeated.
