Description

Technical Field

[0001] The invention relates to the technical field of casing casting equipment, in particular to a combined pump casing casting mould and a use method thereof. Background Art

[0002] Cast iron has good corrosion resistance and is widely used in pump body casings. It is also manufactured by casting during production, which can relatively reduce the production cost. The casting method of the automobile engine water pump casing realizes the rapid and accurate casting of the automobile engine water pump casing through the steps of making a casting mold, combining sand cores and closing the mold, flipping pouring, cooling and molding, sand dropping and product testing, etc., which solves the problems of complex casting process of the automobile engine water pump casing and poor inner cavity molding effect of the automobile engine water pump casing in the prior art.

[0003] Among them, after the casing is cast, it is limited to be in a three-dimensional state, and the outer wall of the casing has a large contact area with the mold, which causes the casing to be subjected to a large demolding force when the equipment is demolded. If conventional push rod demolding is used, the casing will be slightly deformed by the thrust during the demolding process. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a combined pump body casing casting mold, comprising a base, a telescopic rod is fixedly connected to the top of the base, a mounting plate is fixedly connected to one end of the telescopic rod away from the base, and a top mold is fixedly connected to the bottom of the mounting plate;

[0005] The pneumatic mechanism includes a pneumatic box fixedly connected to the top of the base, a one-way air inlet valve is connected through the side wall of the pneumatic box, a fixing plate is fixedly connected to the inner wall of the pneumatic box, and an electric telescopic rod is fixedly connected to the top of the fixing plate;

[0006] The discharging mechanism includes a piston mold fixedly connected to one end of the electric telescopic rod away from the fixed plate, six horn grooves are opened at the bottom of the piston mold, and exhaust grooves are opened at the inner walls of the six horn grooves. A fixed plate 1 is fixedly connected to the inner wall of the exhaust groove, and a piston block 1 is slidably connected to the inner wall of the fixed plate 1. An L-shaped rod is fixedly connected to the bottom of the fixed plate 1, and a spring rod is slidably connected to the inner wall of the L-shaped rod. A fixed plate 2 is fixedly connected to the inner wall of the exhaust groove, and a sliding frame is fixedly connected to the bottom of the fixed plate 2. A cross blocking plate is slidably connected to the inner wall of the fixed plate 2, and a pulling rod is fixedly connected to the bottom of the cross blocking plate. The bottom of the sliding frame is fixedly connected with a hydraulic telescopic rod 1, the bottom of the sliding frame is fixedly connected with a hydraulic cylinder, the inner wall of the hydraulic cylinder is slidably connected with a piston block 2, the bottom of the piston block 2 is fixedly connected with a fixed rod, the inner wall of the horn groove is slidably connected with a blocking component, and the bottom of the piston mold is fixedly connected with an exhaust component. In order to solve the problem of casing deformation during demoulding of the push rod, a pneumatic mechanism and a discharging mechanism are arranged inside the equipment. Before use, the base and the mounting plate are installed inside the die pressing device, and then the power of the electric telescopic rod is turned on, forcing the electric telescopic rod to drive the piston mold to reach the highest point along the inner wall of the air pressure box, presenting as shown in the figure. Figure 1 The state shown, then the die pressing device forces the top mold to contact the piston mold, and starts the casting process. After the equipment completes casting and cools, the electric telescopic rod generates a contraction force, forcing the piston mold to slide downward along the inner wall of the air pressure box. In this process, a closed space is formed between the piston mold and the inside of the air pressure box, and as the piston mold moves downward, the air in the closed space will form high-pressure gas, and the high-pressure gas will force the piston block 1 to move upward, so that a gap is formed between the piston block 1 and the fixed plate 1, so that the air in the closed space enters the exhaust groove through the above gap, and when the piston block 1 moves upward, the piston block 1 drives the piston block 2 to move upward along the inner wall of the hydraulic cylinder through the fixed rod, so that the solution inside the hydraulic cylinder enters the inside of the hydraulic telescopic rod 1, so that the hydraulic telescopic rod 1 extends outward, and the hydraulic telescopic rod 1 drives the cross blocking plate to slide downward along the inner wall of the fixed plate 2 through the pulling frame, presenting as shown in the figure. Figure 6 The state allows the high-pressure gas inside the exhaust groove to be ejected outward through the gap between the cross blocking plate and the second fixed plate. At this time, the high-pressure gas acts on the bottom of the shell, forcing the shell to rise with an upward thrust, completing the demoulding process. The high-pressure gas replaces the gas demoulding, effectively reducing the thrust received by the shell during demoulding.

[0007] Preferably, the blocking assembly includes four inclined grooves opened on the inner wall of the horn groove, and the inner walls of the four inclined grooves are slidably connected with baffles. The outer wall of the piston mold is slidably connected to the inner wall of the air pressure box. As the high-pressure gas enters the gap between the shell and the top of the piston mold, as the shell and the piston mold are gradually separated, the contact area between the high-pressure gas and the shell will continue to expand. As the contact area expands, the area where the shell is subjected to force also continues to expand. The increase in the force area will effectively avoid deformation of the shell caused by a small force area of ​​the shell.

[0008] Preferably, the exhaust assembly includes six circular rings fixedly connected to the bottom of the piston mold, the inner walls of the six circular rings are fixedly connected to through-hole brackets, the inner walls of the through-hole brackets are slidably connected to a gear rod 1, and the above-mentioned gas demolding process is utilized, and a blocking assembly is provided inside the equipment, after one of the exhaust grooves sprays the high-pressure gas outward, due to the large area of ​​the casing, it will be difficult for the high-pressure gas to completely separate the top of the piston mold from the outer wall of the casing, and it is easy for part of the high-pressure gas to be discharged outward through the gap between the top of the piston mold and the casing. To address the above problem, before the high-pressure gas enters the exhaust groove, it needs to pass through the gap between the baffle and the horn groove. At this time, when the equipment is running, the baffle will present two states: one, the high-pressure gas is not discharged outward through the gap between the top of the piston mold and the casing. At this time, the flow rate of the gas between the baffle and the horn groove is slow, and the high-pressure gas can directly pass through the gap between the baffle and the horn groove.

[0009] Preferably, the exhaust component also includes a gear rod 2 slidably connected to the inner wall of the through-hole bracket, a gear is rotatably connected to the inner wall of the through-hole bracket, and a spring 1 is fixedly connected to the top of the through-hole bracket. When the high-pressure gas is discharged outward through the gap between the top of the piston mold and the casing, the high-pressure gas will quickly pass through the gap between the horn groove and the baffle, and the baffle will be subjected to an upward thrust, forcing the baffle to slide upward along the inner wall of the inclined groove, forcing the baffle to completely block the horn groove. Through the application of the above-mentioned components, it is possible to avoid a single cross blocking plate causing the high-pressure gas at the bottom of the air pressure box to release pressure after completing the gas discharge, thereby affecting the remaining discharge effects.

[0010] Preferably, one end of the spring 1 far fixed rod is fixedly connected to the bottom of the baffle, and the top of the gear rod 1 is fixedly connected to the bottom of the baffle. By utilizing the characteristics of the above-mentioned baffle blocking the horn groove, an exhaust assembly is arranged inside the equipment. When the baffle moves upward, the baffle drives the gear rod 1 to move upward synchronously. At this time, the gear rod 1 forces the gear to rotate, and the rotation of the gear will force the gear rod 2 to slide downward along the inner wall of the through-hole bracket to form a waiting state. After the multiple baffles block the gear rod 1, the electric telescopic rod will drive the piston mold to continue to move downward along the inner wall of the air pressure box. At this time, the piston mold is The baffle is blocked, and when the piston mold moves downward, the gas inside the air pressure box will be compressed, so that the gas inside the air pressure box is converted into high-pressure gas. In the process of the piston mold moving downward, the bottom of the gear rod 2 will contact the top of the fixed plate, and the upward gear rod 2 will force the baffle to move away from the inner wall of the horn groove, so that the baffle no longer blocks the horn groove, and the high-pressure gas will be discharged outward through multiple cross blocking plates again, and act on the outer wall of the shell to avoid the outer wall of the shell from being stuck to the top of the piston mold. Through the application of the above components, the jamming phenomenon of the shell can be effectively reduced.

[0011] Preferably, the outer wall of the gear is meshed and connected with the outer wall of gear rod 1, and the outer wall of the gear is meshed and connected with the outer wall of gear rod 2. After the equipment completes discharging, the electric telescopic rod will generate an extension force to force the piston mold to slide upward along the inner wall of the air pressure box. During this process, piston block 1 will block the inner wall of fixed plate 1. At this time, the piston mold will form a closed plate. As the electric telescopic rod drives the piston mold to move upward, the air pressure box will draw external air into the air pressure box through the one-way air inlet valve to replenish the gas inside the air pressure box. During the process of exhausting air with the one-way air inlet valve, the spring rod will force piston block 1 to move downward, and piston block 1 will force piston block 2 to reset along the inner wall of the hydraulic cylinder. When the hydraulic telescopic rod 1 contracts, the cross blocking plate will move upward, so that the top of the cross blocking plate is parallel to the top of fixed plate 2. Through the application of the above-mentioned components, while ensuring that the various components of the equipment are reset, conditions are provided for subsequent casting, thereby improving the processing efficiency of the equipment.

[0012] Preferably, one end of the hydraulic telescopic rod away from the sliding frame is fixedly connected to the top of the pulling frame, the side wall of the hydraulic cylinder is through-connected to the side wall of the hydraulic telescopic rod, and one end of the fixed rod away from the piston block is fixedly connected to the top of the piston block.

[0013] A method for using a combined pump body casing casting mold includes the following steps:

[0014] S1: Install equipment;

[0015] S2: Turn on the power;

[0016] S3: Start demoulding.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention aims to solve the problem of casing deformation during demolding of the push rod. A pneumatic mechanism and a discharging mechanism are arranged inside the device. Before use, the base and the mounting plate are installed inside the die pressing device. Then, the power of the electric telescopic rod is turned on, forcing the electric telescopic rod to drive the piston mold along the inner wall of the pneumatic box to reach the highest point, showing the following Figure 1 The state shown, then the die pressing device forces the top mold to contact the piston mold, and starts the casting process. After the equipment completes casting and cools, the electric telescopic rod generates a contraction force, forcing the piston mold to slide downward along the inner wall of the air pressure box. In this process, a closed space is formed between the piston mold and the inside of the air pressure box, and as the piston mold moves downward, the air in the closed space will form high-pressure gas, and the high-pressure gas will force the piston block 1 to move upward, so that a gap is formed between the piston block 1 and the fixed plate 1, so that the air in the closed space enters the exhaust groove through the above gap, and when the piston block 1 moves upward, the piston block 1 drives the piston block 2 to move upward along the inner wall of the hydraulic cylinder through the fixed rod, so that the solution inside the hydraulic cylinder enters the inside of the hydraulic telescopic rod 1, so that the hydraulic telescopic rod 1 extends outward, and the hydraulic telescopic rod 1 drives the cross blocking plate to slide downward along the inner wall of the fixed plate 2 through the pulling frame, presenting as shown in the figure. Figure 6 state, so that the high-pressure gas inside the exhaust groove can be ejected outward through the gap between the cross blocking plate and the second fixed plate. At this time, the high-pressure gas acts on the bottom of the shell, forcing the shell to rise with an upward thrust, completing the demoulding process. The high-pressure gas is used instead of the gas demoulding to effectively reduce the thrust received by the shell during demoulding. In addition, as the high-pressure gas enters the gap between the shell and the top of the piston mold, as the shell and the piston mold are gradually separated, the contact area between the high-pressure gas and the shell will continue to expand. As the contact area expands, the area of ​​the shell subjected to force also continues to expand. The increase in the force area will effectively avoid the deformation of the shell caused by the small force area of ​​the shell.

[0019] (2) The present invention utilizes the above-mentioned gas demoulding process and is provided with a plugging component inside the device. After one of the exhaust grooves ejects the high-pressure gas outward, due to the large area of ​​the casing, it will be difficult for the high-pressure gas to completely separate the top of the piston mold from the outer wall of the casing, and it is easy for part of the high-pressure gas to be discharged outward through the gap between the top of the piston mold and the casing. To address the above problem, before the high-pressure gas enters the exhaust groove, it needs to pass through the gap between the baffle plate and the horn groove. At this time, when the device is running, the baffle plate will present two states: one, the high-pressure gas does not pass through the gap between the top of the piston mold and the casing. The high-pressure gas is discharged outward through the gap between the top of the piston mold and the casing, at this time, the high-pressure gas will quickly pass through the gap between the horn groove and the baffle, and at this time the baffle will be subjected to an upward thrust, forcing the baffle to slide upward along the inner wall of the inclined groove, forcing the baffle to completely block the horn groove. Through the application of the above components, it is avoided that a single cross blocking plate will cause the high-pressure gas at the bottom of the air pressure box to release pressure after completing the gas discharge, thereby affecting the remaining discharge effects.

[0020] (3) The present invention utilizes the characteristic of the baffle plate blocking the horn groove, and an exhaust component is arranged inside the equipment. When the baffle plate moves upward, the baffle plate drives the gear rod 1 to move upward synchronously. At this time, the gear rod 1 forces the gear to rotate, and the rotation of the gear will force the gear rod 2 to slide downward along the inner wall of the through-hole bracket to form a waiting state. After the multiple baffle plates block the gear rod 1, the electric telescopic rod will drive the piston mold to continue to move downward along the inner wall of the air pressure box. At this time, the piston mold is blocked by the baffle plate. When the piston mold moves downward, the gas inside the air pressure box will be compressed to convert the gas inside the air pressure box into high-pressure gas. In the process of the piston mold moving downward, the bottom of the gear rod 2 will contact the top of the fixed plate. The upward gear rod 2 will force the baffle plate to move away from the inner wall of the horn groove, so that the baffle plate no longer blocks the horn groove, and the high-pressure gas will be discharged outward again through the multiple cross blocking plates and act on the outer wall of the shell to avoid the outer wall of the shell outer wall and the top of the piston mold still being in a sticky state. Through the application of the above-mentioned components, the jamming phenomenon of the shell can be effectively reduced.

[0021] (4) After the equipment of the present invention completes material discharge, the electric telescopic rod will generate an extension force, forcing the piston mold to slide upward along the inner wall of the air pressure box. During this process, the piston block 1 will block the inner wall of the fixed plate 1. At this time, the piston mold will form a closed plate. As the electric telescopic rod drives the piston mold to move upward, the air pressure box will absorb external air into the air pressure box through the one-way air inlet valve to replenish the gas inside the air pressure box. During the process of the one-way air inlet valve evacuating air, the spring rod will force the piston block 1 to move downward, and the piston block 1 will force the piston block 2 to reset along the inner wall of the hydraulic cylinder. When the hydraulic telescopic rod 1 contracts, the cross blocking plate will move upward, so that the top of the cross blocking plate is parallel to the top of the fixed plate 2. Through the application of the above components, while ensuring that the various components of the equipment are reset, conditions are provided for subsequent casting, thereby improving the processing efficiency of the equipment.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figure 1 - Figure 6 The present invention is a combined pump casing casting mold, comprising a base 1, a telescopic rod 11 is fixedly connected to the top of the base 1, a mounting plate 12 is fixedly connected to one end of the telescopic rod 11 away from the base 1, and a top mold 13 is fixedly connected to the bottom of the mounting plate 12;

[0037] The pneumatic mechanism 2 includes a pneumatic box 21 fixedly connected to the top of the base 1, a one-way air inlet valve 22 is connected through the side wall of the pneumatic box 21, a fixing plate 23 is fixedly connected to the inner wall of the pneumatic box 21, and an electric telescopic rod 24 is fixedly connected to the top of the fixing plate 23;

[0038] The discharging mechanism 3 includes a piston mold 31 fixedly connected to the end of the electric telescopic rod 24 away from the fixed plate 23, six horn grooves 32 are provided at the bottom of the piston mold 31, and exhaust grooves 33 are provided at the inner walls of the six horn grooves 32. A fixed plate 1 34 is fixedly connected to the inner wall of the exhaust groove 33, and a piston block 1 35 is slidably connected to the inner wall of the fixed plate 1 34. An L-shaped rod 36 is fixedly connected to the bottom of the fixed plate 1 34, and a spring rod 37 is slidably connected to the inner wall of the L-shaped rod 36. A fixed plate 2 38 is fixedly connected to the inner wall of the exhaust groove 33, and a sliding frame 39 is fixedly connected to the bottom of the fixed plate 2 38. A cross blocking plate 310 is slidably connected to the inner wall of the fixed plate 2 38, and the bottom of the cross blocking plate 310 is fixedly connected to Pulling frame 311, the bottom of the sliding frame 39 is fixedly connected with a hydraulic telescopic rod 1 312, the bottom of the sliding frame 39 is fixedly connected with a hydraulic cylinder 313, the inner wall of the hydraulic cylinder 313 is slidably connected with a piston block 2 314, the bottom of the piston block 214 is fixedly connected with a fixed rod 315, the inner wall of the horn groove 32 is slidably connected with a blocking component 4, and the bottom of the piston mold 31 is fixedly connected with an exhaust component 5. In order to solve the problem of casing deformation during push rod demoulding, a pneumatic mechanism 2 and a discharging mechanism 3 are arranged inside the equipment. Before use, the base 1 and the mounting plate 12 are installed inside the die pressing device, and then the power of the electric telescopic rod 24 is turned on, forcing the electric telescopic rod 24 to drive the piston mold 31 to reach the highest point along the inner wall of the pneumatic box 21, presenting as shown Figure 1 In the state shown, the die pressing device then forces the top mold 13 to contact the piston mold 31 and starts the casting process. After the equipment completes the casting and cools down, the electric telescopic rod 24 generates a contraction force, forcing the piston mold 31 to slide downward along the inner wall of the air pressure box 21. During this process, the piston mold 31 and the inside of the air pressure box 21 form a closed space, and as the piston mold 31 moves downward, the air in the closed space will form high-pressure gas, and the high-pressure gas will force the piston block 35 to move upward, causing the piston block 35 to slide downward. A gap is formed between the piston block 1 35 and the fixed plate 1 34, so that the air in the enclosed space enters the exhaust groove 33 through the above gap. When the piston block 1 35 moves upward, the piston block 1 35 drives the piston block 2 314 to move upward along the inner wall of the hydraulic cylinder 313 through the fixed rod 315, so that the solution in the hydraulic cylinder 313 enters the hydraulic telescopic rod 1 312, so that the hydraulic telescopic rod 1 312 extends outward, and the hydraulic telescopic rod 1 312 drives the cross blocking plate 310 to slide downward along the inner wall of the fixed plate 2 38 through the pulling frame 311, presenting a Figure 6 The state allows the high-pressure gas inside the exhaust groove 33 to be ejected outward through the gap between the cross blocking plate 310 and the fixing plate 38. At this time, the high-pressure gas acts on the bottom of the shell, forcing the shell to rise with an upward thrust, completing the demoulding process. The high-pressure gas replaces the gas demoulding, which effectively reduces the thrust received by the shell during demoulding.

[0039] For example 2, please refer to Figure 7 - Fig.10 The present invention is a combined pump body casing casting mold. On the basis of the first embodiment, the blocking component 4 includes four inclined grooves 41 opened on the inner wall of the trumpet groove 32, and the inner wall of the four inclined grooves 41 is slidably connected with a baffle 42. The outer wall of the piston mold 31 is slidably connected to the inner wall of the air pressure box 21. When the high-pressure gas enters the gap between the shell and the top of the piston mold 31, as the shell and the piston mold 31 are gradually separated, the contact area between the high-pressure gas and the shell will continue to expand. At the same time, the area of ​​the shell subjected to force is also continuously expanded. The increase in the force area will effectively avoid the deformation of the shell caused by the small force area of ​​the shell.

[0040] The exhaust component 5 includes six circular rings 51 fixedly connected to the bottom of the piston mold 31, and the inner walls of the six circular rings 51 are fixedly connected to the through-hole brackets 52, and the inner walls of the through-hole brackets 52 are slidably connected to the gear rods 53. Utilizing the above-mentioned gas demoulding process, a blocking component 4 is arranged inside the equipment. After one of the exhaust grooves 33 ejects the high-pressure gas outward, due to the large area of ​​the casing, it will be difficult for the high-pressure gas to completely separate the top of the piston mold 31 from the outer wall of the casing, and it is easy for part of the high-pressure gas to be discharged outward through the gap between the top of the piston mold 31 and the casing. In view of the above problem, before the high-pressure gas enters the exhaust groove 33, it needs to pass through the gap between the baffle 42 and the horn groove 32. At this time, when the equipment is running, the baffle 42 will present two states. First, the high-pressure gas is not discharged outward through the gap between the top of the piston mold 31 and the casing. At this time, the flow rate of the gas between the baffle 42 and the horn groove 32 is slow, and the high-pressure gas can directly pass through the gap between the baffle 42 and the horn groove 32.

[0041] The exhaust component 5 also includes a gear rod 54 slidably connected to the inner wall of the through-hole bracket 52, a gear 55 is rotatably connected to the inner wall of the through-hole bracket 52, and a spring 56 is fixedly connected to the top of the through-hole bracket 52. When the high-pressure gas is discharged outward through the gap between the top of the piston mold 31 and the casing, the high-pressure gas will quickly pass through the gap between the horn groove 32 and the baffle 42, and the baffle 42 will be subjected to an upward thrust, forcing the baffle 42 to slide upward along the inner wall of the inclined groove 41, forcing the baffle 42 to completely block the horn groove 32. Through the application of the above-mentioned components, it is avoided that a single cross blocking plate 310 will cause the high-pressure gas at the bottom of the air pressure box 21 to release pressure after completing the gas discharge, thereby affecting the remaining discharge effects.

[0042] One end of the far fixed rod 315 of the spring 1 56 is fixedly connected to the bottom of the baffle 42, and the top of the gear rod 1 53 is fixedly connected to the bottom of the baffle 42. By utilizing the characteristic that the baffle 42 blocks the horn groove 32, an exhaust assembly 5 is arranged inside the equipment. When the baffle 42 moves upward, the baffle 42 drives the gear rod 1 53 to move upward synchronously. At this time, the gear rod 1 53 forces the gear 55 to rotate, and the rotation of the gear 55 will force the gear rod 2 54 to slide downward along the inner wall of the through-hole bracket 52 to form a waiting state. After the multiple baffles 42 block the gear rod 1 53, the electric telescopic rod 24 will drive the piston mold 31 to continue to move downward along the inner wall of the air pressure box 21. At this time, the piston The mold 31 is blocked by the baffle 42. When the piston mold 31 moves downward, the gas inside the air pressure box 21 will be compressed, so that the gas inside the air pressure box 21 is converted into high-pressure gas. In the process of the piston mold 31 moving downward, the bottom of the gear rod 2 54 will contact the top of the fixed plate 23. The upward gear rod 2 54 will force the baffle 42 to move away from the inner wall of the horn groove 32, so that the baffle 42 no longer blocks the horn groove 32, and the high-pressure gas will be discharged outward again through multiple cross blocking plates 310 and act on the outer wall of the shell to avoid the outer wall of the shell and the top of the piston mold 31 Still in adhesion, through the application of the above-mentioned components, the jamming phenomenon of the shell can be effectively reduced.

[0043] The outer wall of the gear 55 is meshed with the outer wall of the gear rod 1 53, and the outer wall of the gear 55 is meshed with the outer wall of the gear rod 2 54. After the equipment completes the discharge, the electric telescopic rod 24 will generate an extension force to force the piston mold 31 to slide upward along the inner wall of the air pressure box 21. During this process, the piston block 1 35 will block the inner wall of the fixed plate 1 34. At this time, the piston mold 31 will form a closed plate. As the electric telescopic rod 24 drives the piston mold 31 to move upward, the air pressure box 21 will absorb external air into the air pressure box 21 through the one-way air inlet valve 22. Inside, the gas inside the air pressure box 21 is replenished, and during the process of exhausting air from the one-way air inlet valve 22, the spring rod 37 will force the piston block 1 35 to move downward, and the piston block 1 35 will force the piston block 2 314 to reset along the inner wall of the hydraulic cylinder 313. While the hydraulic telescopic rod 1 312 contracts, the cross blocking plate 310 will move upward, so that the top of the cross blocking plate 310 is parallel to the top of the fixed plate 2 38. Through the application of the above-mentioned components, while ensuring that the various components of the equipment are reset, conditions are provided for subsequent casting, thereby improving the processing efficiency of the equipment.

[0044] One end of the hydraulic telescopic rod 312 away from the sliding frame 39 is fixedly connected to the top of the pulling frame 311, the side wall of the hydraulic cylinder 313 is through-connected to the side wall of the hydraulic telescopic rod 312, and one end of the fixed rod 315 away from the piston block 2 314 is fixedly connected to the top of the piston block 1 35.

[0045] The method for using the combined pump body casing casting mold includes the following steps:

[0046] S1: Install equipment;

[0047] S2: Turn on the power;

[0048] S3: Start demoulding.

[0049] A specific application of this embodiment is: before use, the base 1 and the mounting plate 12 are installed inside the die pressing device, and then the power of the electric telescopic rod 24 is turned on, forcing the electric telescopic rod 24 to drive the piston mold 31 along the inner wall of the air pressure box 21 to reach the highest point, presenting as shown Figure 1 In the state shown, the die pressing device then forces the top mold 13 to contact the piston mold 31 and starts the casting process. After the equipment completes the casting and cools down, the electric telescopic rod 24 generates a contraction force, forcing the piston mold 31 to slide downward along the inner wall of the air pressure box 21. During this process, the piston mold 31 and the inside of the air pressure box 21 form a closed space, and as the piston mold 31 moves downward, the air in the closed space will form high-pressure gas, and the high-pressure gas will force the piston block 35 to move upward, causing the piston block 35 to slide downward. A gap is formed between the piston block 1 35 and the fixed plate 1 34, so that the air in the enclosed space enters the exhaust groove 33 through the above gap. When the piston block 1 35 moves upward, the piston block 1 35 drives the piston block 2 314 to move upward along the inner wall of the hydraulic cylinder 313 through the fixed rod 315, so that the solution in the hydraulic cylinder 313 enters the hydraulic telescopic rod 1 312, so that the hydraulic telescopic rod 1 312 extends outward, and the hydraulic telescopic rod 1 312 drives the cross blocking plate 310 to slide downward along the inner wall of the fixed plate 2 38 through the pulling frame 311, presenting a Figure 6 state, so that the high-pressure gas inside the exhaust groove 33 can be ejected outward through the gap between the cross blocking plate 310 and the fixed plate 38. At this time, the high-pressure gas acts on the bottom of the shell, forcing the shell to rise with an upward thrust, completing the demoulding process. The high-pressure gas is used instead of the gas demoulding, which effectively reduces the thrust received by the shell during demoulding. In addition, as the high-pressure gas enters the gap between the shell and the top of the piston mold 31, as the shell and the piston mold 31 are gradually separated, the contact area between the high-pressure gas and the shell will continue to expand. As the contact area expands, the area where the shell is subjected to force also continues to expand. The increase in the force area will effectively avoid deformation of the shell due to the small force area of ​​the shell.

[0050] By utilizing the above-mentioned gas demoulding process, a blocking component 4 is provided inside the equipment. After one of the exhaust grooves 33 ejects the high-pressure gas outward, due to the large area of ​​the casing, it will be difficult for the high-pressure gas to completely separate the top of the piston mold 31 from the outer wall of the casing, and it is easy for part of the high-pressure gas to be discharged outward through the gap between the top of the piston mold 31 and the casing. In view of the above problem, before the high-pressure gas enters the exhaust groove 33, it needs to pass through the gap between the baffle plate 42 and the horn groove 32. At this time, when the equipment is running, the baffle plate 42 will present two states: one, the high-pressure gas is not discharged outward through the gap between the top of the piston mold 31 and the casing. At this time, the baffle plate 42 The flow rate of the gas between the plate 42 and the horn groove 32 is slow, and the high-pressure gas can directly pass through the gap between the baffle 42 and the horn groove 32; secondly, when the high-pressure gas is discharged outward through the gap between the top of the piston mold 31 and the casing, the high-pressure gas will quickly pass through the gap between the horn groove 32 and the baffle 42, and at this time the baffle 42 will be subjected to an upward thrust, forcing the baffle 42 to slide upward along the inner wall of the inclined groove 41, forcing the baffle 42 to completely block the horn groove 32. Through the application of the above-mentioned components, it is avoided that a single cross blocking plate 310 will cause the high-pressure gas at the bottom of the air pressure box 21 to release pressure after completing the gas discharge, thereby affecting the remaining discharge effects.

[0051] Taking advantage of the feature of the baffle 42 blocking the horn slot 32, an exhaust assembly 5 is provided inside the device. When the baffle 42 moves upward, the baffle 42 drives the gear rod 1 53 to move upward synchronously. At this time, the gear rod 1 53 forces the gear 55 to rotate, and the rotation of the gear 55 forces the gear rod 2 54 to slide downward along the inner wall of the through-hole bracket 52 to form a waiting state. After the multiple baffles 42 block the gear rod 1 53, the electric telescopic rod 24 drives the piston mold 31 to continue to move downward along the inner wall of the air pressure box 21. At this time, the piston mold 31 is blocked by the baffle 42. When the piston mold 31 moves downward, The gas inside the air pressure box 21 is compressed to convert the gas inside the air pressure box 21 into high-pressure gas, and in the process of the piston mold 31 moving downward, the bottom of the gear rod 2 54 will contact the top of the fixed plate 23, and the upward gear rod 2 54 will force the baffle 42 to move away from the inner wall of the horn groove 32, so that the baffle 42 no longer blocks the horn groove 32, and the high-pressure gas will be discharged outward again through multiple cross blocking plates 310 and act on the outer wall of the shell to avoid the outer wall of the shell and the top of the piston mold 31 still being stuck. Through the application of the above-mentioned components, the jamming phenomenon of the shell can be effectively reduced.

[0052] After the equipment completes discharging, the electric telescopic rod 24 will generate an extension force, forcing the piston mold 31 to slide upward along the inner wall of the air pressure box 21. During this process, the piston block 35 will block the inner wall of the fixed plate 34. At this time, the piston mold 31 will form a closed plate. As the electric telescopic rod 24 drives the piston mold 31 to move upward, the air pressure box 21 will absorb external air into the air pressure box 21 through the one-way air inlet valve 22 to replenish the gas inside the air pressure box 21. During the process of the one-way air inlet valve 22 exhausting air, the spring rod 37 will force the piston block 35 to move downward, and the piston block 35 will force the piston block 2 314 to reset along the inner wall of the hydraulic cylinder 313. While the hydraulic telescopic rod 1 312 contracts, the cross blocking plate 310 will move upward, so that the top of the cross blocking plate 310 is parallel to the top of the fixed plate 2 38. Through the application of the above-mentioned components, while ensuring that the various components of the equipment are reset, conditions are provided for subsequent casting, thereby improving the processing efficiency of the equipment.
