Description

Technical Field

[0001] This utility model belongs to the field of water pump body casting technology, specifically relating to a water pump body casting mold with built-in guide ribs. Background Technology

[0002] Existing water pumps, characterized by high pressure, large flow rate, compact structure, low noise, long service life, fast response, and strong impact resistance, have only recently been domestically produced and are widely used in industries such as shipbuilding, steel, machine tools, mining, and tin-magnesium products. Casting molds are used to obtain the structural shape of a part by first creating the part's shape from other easily formable materials, then placing the mold in a sand mold. This creates a cavity in the sand mold with the same dimensions as the part's structure. A fluid liquid is then poured into this cavity, and after cooling and solidifying, a part with the exact same shape and structure as the mold is formed. Water pump bodies are produced using casting molds.

[0003] In the existing water pump body casting mold, the casting liquid needs to cool and solidify before it can be completed. However, the existing mold does not have a demolding structure, which causes the water pump body to easily stick to the upper mold during demolding. This can lead to the water pump body falling off and being damaged, thus affecting the casting efficiency of the water pump body. Utility Model Content

[0004] The purpose of this utility model is to provide a water pump body casting mold with built-in guide ribs, so as to solve the problem mentioned in the background art that in the casting process of existing water pump body casting molds, the casting liquid needs to wait for cooling and solidification before completion, but the existing molds do not have a demolding structure, which causes the water pump body to easily stick to the upper mold during demolding, resulting in the water pump body falling off and being damaged, thus affecting the casting efficiency of the water pump body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base and an L-shaped bracket mounted on the upper surface of the base. A casting mold cylinder is rotatably mounted on the upper surface of the base via a support assembly. Two fixed plates are mounted on the left side of the upper surface of the base, and a reciprocating screw is rotatably mounted between the two fixed plates. A motor is mounted on the front fixed plate. The front end of the reciprocating screw extends through the fixed plate and is fixedly connected to the output shaft of the motor. A slide is threaded onto the reciprocating screw, and a toothed plate is mounted on the right side of the slide. An external toothed ring that meshes with the toothed plate is mounted on the outer surface of the casting mold cylinder. An electric push rod is mounted on the lower surface of the transverse portion of the bracket. A support plate is mounted on the rear end of the output shaft of the electric push rod. An upper mold column is mounted on the lower surface of the support plate. Two elastic injection pipes are connected and mounted on the bracket and the support plate. An injection hole is opened on the lower surface of the upper mold column, and the injection pipes are connected to the injection hole. The top ends of the two injection pipes are connected and mounted with the same external connecting pipe.

[0006] By adopting the above scheme, a motor, a toothed plate, an external toothed ring, and an electric push rod are set up. The fixed plate supports the rotation of the reciprocating screw. Combined with the motor driving the reciprocating screw to rotate, the slide drives the toothed plate to move. With the toothed plate meshing with the gear, the casting mold cylinder rotates repeatedly clockwise and counterclockwise under the drive of the external toothed ring. This loosens and separates the casting mold cylinder from the upper mold column, preventing the water pump body inside the casting mold cylinder from sticking to the upper mold column, thus protecting the water pump body and improving the casting efficiency of the water pump body.

[0007] In the above scheme, it should be noted that the electric push rod one and electric push rod two are all electrically connected to an external power source.

[0008] In a preferred embodiment, two limiting rods are slidably installed through the horizontal portion of the bracket. The two limiting rods are located on the front and rear sides of the electric push rod, respectively. The bottom end of the limiting rod is fixedly connected to the support plate, and the top end of the limiting rod is equipped with a top plate.

[0009] By adopting the above scheme, by setting a limiting rod and a top plate, the limiting rod is slidably installed on the bracket to strengthen the support plate, thereby improving the stability and firmness of the support plate. This allows the support plate to stably support the upper mold column, and the top plate, in conjunction with the top plate, seals the top of the limiting rod.

[0010] In a preferred embodiment, the support assembly includes an annular support ring mounted on the upper surface of the base, and an annular groove is formed on the lower surface of the casting mold cylinder, with the top end of the support ring rotatably mounted within the annular groove.

[0011] By adopting the above scheme, a support ring is set up, and the top of the support ring rotates in the annular groove to provide rotational support for the casting mold cylinder, thereby enabling the casting mold cylinder to rotate stably and improving the stability of the casting mold cylinder.

[0012] In a preferred embodiment, the inner bottom surface of the casting mold cylinder is provided with an ejector hole, the upper surface of the base is provided with a through hole corresponding to the ejector hole, the lower surface of the base is equipped with an electric push rod II, an ejector plate is provided in the ejector hole, and the output shaft of the electric push rod II passes through the through hole and extends into the ejector hole to be fixedly connected to the ejector plate.

[0013] By adopting the above scheme, by setting up an electric push rod two and an ejector plate, the output shaft of the electric push rod two is accommodated by the ejector hole and the through hole. Combined with the action of the output shaft of the electric push rod two driving the ejector plate to move, the cast water pump body can be easily moved out of the casting mold, thereby facilitating the quick removal of the cast water pump body.

[0014] In a preferred embodiment, a retaining ring is installed inside the ejector hole, the output shaft of the second electric push rod extends through the retaining ring, and two positioning rods are installed on the lower surface of the ejector plate, with the bottom end of the positioning rods abutting against the retaining ring.

[0015] By adopting the above scheme, by setting a fixing ring and a positioning rod, the fixed ring is located in the ejection hole to limit and support the output shaft of the electric push rod two, so that the output shaft of the electric push rod two can stably drive the ejection plate to move. Combined with the action of the positioning rod and the fixing ring, the downward movement distance of the ejection plate is controlled, so that the upper surface of the ejection plate is on the same horizontal plane as the inner bottom surface of the casting mold cylinder.

[0016] In a preferred embodiment, a connecting plate is installed on the lower surface of the slide block, and a telescopic rod is installed on one of the opposite sides of the two fixed plates. The telescopic shafts of the two telescopic rods are fixedly connected to the connecting plate.

[0017] By adopting the above solution, a connecting plate and a telescopic rod are set up. The connecting plate connects and fixes the telescopic shafts of the telescopic rods on both sides. Combined with the extension of the telescopic rod, the slide is limited and supported, so that the slide can move back and forth stably and avoid the slide from rotating.

[0018] In a preferred embodiment, four insert rods are rotatably mounted on the lower surface of the support plate via a rotating assembly, and four slots are provided on the upper surface of the casting mold cylinder to cooperate with the insert rods.

[0019] By adopting the above scheme, by setting up the insert rod, the upper mold column and the casting mold cylinder can be stably engaged by the cooperation of the insert rod and the slot, thereby improving the sealing between the upper mold column and the casting mold cylinder, and thus enabling stable casting operations.

[0020] In a preferred embodiment, the rotating assembly includes a wedge-shaped rotating ring, and the lower surface of the support plate is provided with a wedge-shaped annular groove. The rotating ring is rotatably installed in the annular groove, and the four insert rods are all installed on the lower surface of the rotating ring.

[0021] By adopting the above scheme, by setting a rotating ring, the top of the rotating ring rotates within the annular groove, so that when the casting mold cylinder rotates with the rotation of the outer toothed ring, the insert rod can rotate with the rotating ring, thereby preventing the insert rod from obstructing the rotation of the casting mold cylinder.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This water pump body casting mold with built-in guide ribs is equipped with a motor, toothed plate, external toothed ring, and electric push rod. The fixed plate supports the reciprocating screw rotation, and the motor drives the reciprocating screw rotation, which causes the slide to drive the toothed plate to move. With the toothed plate meshing with the gear, the casting mold cylinder rotates repeatedly clockwise and counterclockwise under the drive of the external toothed ring. This loosens and separates the casting mold cylinder from the upper mold column, preventing the water pump body inside the casting mold cylinder from sticking to the upper mold column, thus protecting the water pump body and improving the casting efficiency of the water pump body.

[0024] The water pump body casting mold with built-in guide ribs uses a fixed ring and a positioning rod. The fixed ring, located inside the ejector hole, provides limiting support for the output shaft of the electric push rod, allowing the output shaft of the electric push rod to stably drive the ejector plate to move. Combined with the action of the positioning rod against the fixed ring, the downward movement distance of the ejector plate is controlled, so that the upper surface of the ejector plate is on the same horizontal plane as the inner bottom surface of the casting mold cylinder.

[0029] Please see Figure 1-3 This utility model provides a water pump body casting mold with built-in guide ribs, including a base 1 and an L-shaped bracket 2 mounted on the upper surface of the base 1. The bracket 2 is used to fix and support an electric push rod 10. A casting mold cylinder 3 is rotatably mounted on the upper surface of the base 1 through a support assembly. Two fixing plates 4 are mounted on the left side of the upper surface of the base 1, and the fixing plates 4 are used to rotatably support a reciprocating screw 5. The reciprocating screw 5 is rotatably mounted between the two fixing plates 4, and the reciprocating screw 5 drives the slide 7 to move. The fixed plate 7 is located on the front side. A motor 6 is mounted on the fixed plate 4, which drives the reciprocating screw 5 to rotate. The front end of the reciprocating screw 5 extends through the fixed plate 4 and is fixedly connected to the output shaft of the motor 6. A slide 7 is threaded onto the reciprocating screw 5, which provides fixed support for the gear plate 8. The gear plate 8 is mounted on the right side of the slide 7 and meshes with an external gear. An external gear ring 9 that meshes with the gear plate 8 is mounted on the outer surface of the casting mold cylinder 3. An electric push rod 10 is mounted on the lower surface of the transverse part of the bracket 2. The drive support plate 11 moves, and the support plate 11 is installed at the rear end of the output shaft of the electric push rod 10. The support plate 11 is used to fix and support the upper mold column 17. The upper mold column 17 is installed on the lower surface of the support plate 11. Two elastic injection pipes 13 are connected and installed on the bracket 2 and the support plate 11. The lower surface of the upper mold column 17 has an injection hole, and the injection pipes 13 are connected to the injection hole. The top ends of the two injection pipes 13 are connected and installed with the same outer pipe 14. By setting the motor 6, the toothed plate 8, the outer toothed ring 9 and the electric... The push rod 10, using the fixed plate 4 to support the reciprocating screw 5, combined with the motor 6 driving the reciprocating screw 5 to rotate, causes the slide 7 to drive the gear plate 8 to move. With the gear plate 8 meshing with the gear, the casting mold cylinder 3 rotates repeatedly clockwise and counterclockwise under the drive of the outer gear ring 9, thereby loosening and separating the casting mold cylinder 3 from the upper mold column 17, preventing the water pump body inside the casting mold cylinder 3 from sticking to the upper mold column 17, thus protecting the water pump body and improving the casting efficiency of the water pump body.

[0030] Two limiting rods 18 are slidably installed through the horizontal part of the bracket 2. The limiting rods 18 are used to strengthen the support plate 11. The two limiting rods 18 are located on the front and rear sides of the electric push rod 10, respectively. The bottom end of the limiting rod 18 is fixedly connected to the support plate 11, and the top plate 19 is installed on the top of the limiting rod 18. By setting the limiting rod 18 and the top plate 19, the supporting plate 11 is strengthened by the sliding installation of the limiting rod 18 on the bracket 2, thereby improving the stability and firmness of the supporting plate 11. The supporting plate 11 stably supports the upper mold column 17, and the top plate 19 seals the top of the limiting rod 18.

[0031] The support assembly includes an annular support ring 22, which provides rotational support for the casting mold cylinder 3. The support ring 22 is installed on the upper surface of the base 1, and an annular groove is formed on the lower surface of the casting mold cylinder 3. The top end of the support ring 22 is rotatably installed in the annular groove. By setting the support ring 22, the top end of the support ring 22 rotates within the annular groove to provide rotational support for the casting mold cylinder 3, thereby enabling the casting mold cylinder 3 to rotate stably and improving the stability of the casting mold cylinder 3.

[0032] The inner bottom surface of the casting mold cylinder 3 is provided with an ejector hole, which is used to accommodate the ejector plate 25. The upper surface of the base 1 is provided with a through hole corresponding to the ejector hole. An electric push rod 23 is installed on the lower surface of the base 1. The electric push rod 23 drives the ejector plate 25 to move. The ejector plate 25 is set in the ejector hole. The output shaft of the electric push rod 23 extends through the through hole into the ejector hole and is fixedly connected to the ejector plate 25. By setting the electric push rod 23 and the ejector plate 25, the output shaft of the electric push rod 23 is accommodated by the ejector hole and the through hole. Combined with the function of the output shaft of the electric push rod 23 driving the ejector plate 25 to move, it is convenient to remove the cast water pump body from the casting mold cylinder 3, and thus conveniently and quickly remove the cast water pump body.

[0033] A retaining ring 24 is installed inside the ejector hole. The output shaft of the electric push rod 23 extends through the retaining ring 24. Two positioning rods 12 are installed on the lower surface of the ejector plate 25. The bottom end of the positioning rod 12 abuts against the retaining ring 24. By setting the retaining ring 24 and the positioning rods 12, the output shaft of the electric push rod 23 is limited and supported by the retaining ring 24 located inside the ejector hole. This allows the output shaft of the electric push rod 23 to stably drive the ejector plate 25 to move. Combined with the abutting action of the positioning rod 12 against the retaining ring 24, the downward movement distance of the ejector plate 25 is controlled, so that the upper surface of the ejector plate 25 is on the same horizontal plane as the inner bottom surface of the casting mold cylinder 3.

[0034] A connecting plate 20 is installed on the lower surface of the slide 7. Telescopic rods 21 are installed on the opposite sides of the two fixed plates 4. The telescopic shafts of the two telescopic rods 21 are fixedly connected to the connecting plate 20. By setting the connecting plate 20 and the telescopic rods 21, the telescopic shafts of the telescopic rods 21 on both sides are connected and fixed by the connecting plate 20. Combined with the extension of the telescopic rods 21, the slide 7 is limited and supported, so that the slide 7 can move back and forth stably and avoid the phenomenon of rotation of the slide 7.

[0035] Four insert rods 15 are rotatably mounted on the lower surface of the support plate 11 via a rotating assembly. Four slots are provided on the upper surface of the casting mold cylinder 3 to cooperate with the insert rods 15. By setting the insert rods 15, the upper mold column 17 and the casting mold cylinder 3 can be stably engaged by the cooperation of the insert rods 15 and the slots, thereby improving the sealing between the upper mold column and the casting mold cylinder 3, and thus enabling stable casting operations.

[0036] The rotating assembly includes a wedge-shaped rotating ring 16. A wedge-shaped annular groove 2 is provided on the lower surface of the support plate 11. The rotating ring 16 is rotatably installed in the annular groove 2. Four insert rods 15 are all installed on the lower surface of the rotating ring 16. By setting the rotating ring 16, the top of the rotating ring 16 rotates in the annular groove 2, so that when the casting mold cylinder 3 rotates with the rotation of the outer toothed ring 9, the insert rods 15 can rotate with the rotating ring 16, thereby avoiding the insert rods 15 from obstructing the rotation of the casting mold cylinder 3.

[0037] In use, connect the external pipe 14 to the external casting liquid pipe, then start the electric push rod 10. The electric push rod 10 drives the support plate 11 to move downward. The support plate 11 drives the limit rod 18 and the upper mold column 17 to move. The limit rod 18 slides on the bracket 2, and the upper mold column 17 gradually moves downward. At this time, the upper mold column 17 enters the casting mold cylinder 3. The support plate 11 drives the bottom end of the insertion rod 15 into the slot. Then, turn off the electric push rod 10, start the external casting liquid switch, and let the casting liquid enter the injection pipe 13 through the external pipe 14. Then, inject the casting liquid into the casting mold cylinder 3. After the casting liquid is injected, turn off the external casting liquid switch. After the water pump body in the casting mold cylinder 3 is cast, start the motor 6. The motor 6 drives the reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 drives the slide 7 to move. The movement of the slide 7 drives the toothed plate 8 to move, and the toothed plate 8 engages with the... The external gear ring 9 meshes with the casting mold cylinder 3, driving it to rotate. This causes the casting mold cylinder 3 to rotate intermittently clockwise and counterclockwise, accelerating the demolding of the pump body. The rotation of the casting mold cylinder 3 drives the insertion rod 15 to rotate, and the top of the insertion rod 15 drives the rotating ring 16 to rotate. The support ring 22 provides rotational support for the casting mold cylinder 3. After demolding is complete, the motor 6 is turned off, and the electric push rod 10 is reset. At this time, the upper mold column 17 moves out of the casting mold cylinder 3. Then, the electric push rod 23 is activated, driving the ejector plate 25 to move. The ejector plate 25 pushes the pump body upwards, gradually moving the pump body out of the casting mold cylinder 3. The operation is convenient. The connecting plate 20 connects and fixes the telescopic shafts of the telescopic rods 21 on both sides. Combined with the extension of the telescopic rods 21, the slide block 7 is limited and supported, allowing the slide block 7 to move stably back and forth, preventing rotation.
