[0002] The pump housing of a high-pressure pump is often produced through a casting mold, and generally, the sand casting method is used for gravity casting. The molten metal relies on its own gravity and flows from the ladle through the gating system into the mold cavity. This natural gravity-driven method enables the molten metal to flow smoothly and slowly in the cavity, which helps to reduce defects such as turbulence and gas entrapment generated during the filling process of the molten metal.

[0003] When the existing high-pressure pump alloy pump housing is subjected to gravity casting using the sand casting method, it often encounters difficulties in demolding, resulting in the scattering of molding sand, and the efficiency of re-modeling and closing the sand box after demolding is relatively low, affecting the casting efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) Combining the adjusting cylinder facilitates the precise mold closing of the upper sand box and the lower sand box.

[0016] (2) By providing a mating rod at the end of the third connecting plate and controlling the swing frame to rotate by combining the swing motor, the lifting plate is driven to lift. When the lifting plate rises, the card slot and the mating rod cooperate with each other, thereby forming a limiting effect on the third connecting plate, and further ensuring the overall stability of the first connecting plate, the second connecting plate, the third connecting plate, and the installed box body.

[0017] (3) Through the cooperation and locking of the second connecting disk and the mating head with the first connecting disk and the mating hole on the second L-shaped frame, when the flipping demolding mechanism flips, the rotating frame will be driven to rotate synchronously, and the axis of rotation of the rotating frame coincides with the axis of the output shaft of the flipping motor. After the sand box is flipped 90 degrees, control the movement of the first L-shaped frame by combining the adjusting cylinder to separate the upper sand box and the lower sand box, realize the separation of the box body, and then complete the subsequent demolding and mold sand collection operations.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0032] As Figure 1 、 Figure 3 shown, a casting system for a high-pressure pump alloy pump housing includes a base 1 and a mounting plate 10. A lifting drive mechanism 3 is provided at the edge of the base 1. A sand box positioning assembly 2 is provided between the base 1 and the lifting drive mechanism 3. A lower swing positioning assembly 5 is provided at one end of the mounting plate 10 close to the lifting drive mechanism 3, and an edge connection mechanism 6 is provided at the other end of the mounting plate 10. The sand box positioning assembly 2 includes a first connecting plate 20, a second connecting plate 22, and a third connecting plate 23. The two ends of the second connecting plate 22 are respectively rotatably installed between the first connecting plate 20 and the third connecting plate 23. A clamping plate 240 and a fixing plate 250 are respectively installed on the second connecting plate 22. An adjustment groove 220 is provided on the second connecting plate 22. The clamping plate 240 is slidably installed in the adjustment groove 220. An L-shaped frame 24 is connected to the clamping plate 240, and an L-shaped frame 25 is connected to the fixing plate 250. A box body 200 is placed between the L-shaped frame 24 and the L-shaped frame 25. An adjustment cylinder 26 is provided between the fixing plate 250 and the clamping plate 240. A turning demolding mechanism 4 is provided between the first connecting plate 20, the second connecting plate 22, and the third connecting plate 23.

[0033] Specifically, when the first connecting plate 20, the second connecting plate 22, and the third connecting plate 23 are in a vertical state, the space between the first L-shaped frame 24 and the second L-shaped frame 25 is used to place the box body 200. The upper sand box and the lower sand box are respectively slidably clamped on the first L-shaped frame 24 and the second L-shaped frame 25. Combining with the adjusting cylinder 26 facilitates controlling the accurate mold closing of the upper sand box and the lower sand box. Casting the box body 200 in a vertical state, after completion of casting and cooling, the first connecting plate 20, the second connecting plate 22, and the third connecting plate 23 are adjusted to a horizontal state by the lifting driving mechanism 3, and the end of the third connecting plate 23 is connected by the edge connecting mechanism 6. Finally, the second connecting plate 22 and the sand box positioning assembly 2 on the second connecting plate 22 are controlled by the flipping and demolding mechanism 4 to flip by ninety degrees, thereby driving the box body 200 to flip to the upper side of the receiving plate 11. Combining with the edge connecting mechanism 6 and the adjusting cylinder 26, the separation between the first L-shaped frame 24 and the second L-shaped frame 25 is controlled, thereby completing the separation of the box body 200 and realizing the rapid demolding operation.

[0034] Further, as Figure 4 shown, the flipping and demolding mechanism 4 includes a flipping motor 40 arranged in the first connecting plate 20. The output shaft of the flipping motor 40 is connected to the second connecting plate 22. Locking flanges 42 are symmetrically arranged on both sides of the second connecting plate 22. Locking cylinders two 41 are symmetrically arranged on both sides of the first connecting plate 20. The locking cylinders two 41 pass through the locking flanges 42 and are inserted between the first connecting plate 20 and the third connecting plate 23.

[0035] Specifically, before flipping the second connecting plate 22, first control the separation of the locking cylinders two 41 from the third connecting plate 23 and the locking flanges 42 on the side of the second connecting plate 22. Then, combine with the flipping motor 40 to drive the second connecting plate 22 to flip by ninety degrees, driving the box body 200 to flip to the upper side of the receiving plate 11, facilitating the subsequent receiving of the product and the collection of the molding sand during demolding.

[0036] Further, as Figure 4 、 Figure 5 shown, the flipping and demolding mechanism 4 further includes a side plate one 43 arranged at the edge of the first L-shaped frame 24 and a side plate two 44 arranged at the edge of the second L-shaped frame 25. Plugging columns 45 are evenly installed on the side plate one 43 and the side plate two 44. Support springs 46 are sleeved on the plugging columns 45. The plugging columns 45 on the side plate one 43 are inserted between the side plate one 43 and the first L-shaped frame 24. The plugging columns 45 on the side plate two 44 are inserted between the side plate two 44 and the second L-shaped frame 25.

[0037] Specifically, by setting the side plate one 43 and the side plate two 44, the flipped upper sand box and the lower sand box are respectively lifted, ensuring the stability of the box body 200 and the internal castings during the flipping process.

[0038] Further, as Figure 5, Figure 6 As shown, a mating flange 47 is provided at the end of the plug post 45, a receiving plate 11 is provided at the edge of the mounting plate 10, and a sliding groove 12 is provided at a position corresponding to the mating flange 47 on the receiving plate 11.

[0039] Specifically, by providing the mating flange 47 and the sliding groove 12, while forming a reliable support for the box body 200, the resistance received by the end of the plug post 45 during demolding is reduced, and smooth demolding is achieved.

[0040] Furthermore, as Figure 2 shown, the lifting drive mechanism 3 includes a vertical frame 30 provided at the edge of the base 1, a rack 32 is provided on the vertical frame 30, clamping sliding grooves 31 are provided on both sides of the rack 32, a clamping frame 33 is slidably installed between the clamping sliding grooves 31, a mating gear 340 is rotatably installed in the clamping frame 33, the mating gear 340 meshes with the rack 32, the mating gear 340 is connected to a drive motor 34, a linkage plate 35 is provided on the clamping frame 33, a suspension plate 36 is provided on the linkage plate 35, and the end of the suspension plate 36 is rotatably installed with the end of the first connecting plate 20.

[0041] Specifically, the drive motor 34 drives the mating gear 340 to mesh with the rack 32, thereby driving the clamping frame 33 to move up and down along the clamping sliding groove 31, and further driving the linkage plate 35 and the suspension plate 36 to lift and lower, so as to control the attitude adjustment of the sand box positioning assembly 2.

[0042] Furthermore, as Figure 6 , Figure 7 shown, the lower swing positioning assembly 5 includes a guide rail 50 provided on the mounting plate 10, a support wheel 58 is rotatably installed on the third connecting plate 23, the support wheel 58 is cooperatively installed with the guide rail 50, a mating rod 57 is provided at the end of the third connecting plate 23, side frames 51 are provided on both sides of the guide rail 50, a lifting plate 52 is slidably lifted and installed on the edge of the side frame 51, a clamping groove 53 is provided on the lifting plate 52, when the clamping groove 53 cooperates with the mating rod 57, the third connecting plate 23 is in a vertical state, a rotating flange 54 is provided on the side of the lifting plate 52, a swing motor 56 is provided at the end of the guide rail 50, the swing motor 56 is connected to a swing frame 55, and the swing frame 55 is slidably installed with the rotating flange 54.

[0043] Specifically, when the box body 200 is in Figure 3When in the state, the end of the third connecting plate 23 is suspended. To ensure the stability of the sand box positioning assembly 2 during subsequent casting, a mating rod 57 is arranged at the end of the third connecting plate 23. By combining with the swing motor 56 to control the rotation of the swing frame 55, the lifting plate 52 is driven to lift. When the lifting plate 52 rises, the card slot 53 and the mating rod 57 cooperate with each other, thereby forming a limiting effect on the third connecting plate 23, and further ensuring the overall stability of the first connecting plate 20, the second connecting plate 22, the third connecting plate 23 and the installed box body 200.

[0044] Further, as Figure 4 , Figure 8 shown, the edge connection mechanism 6 includes a support plate 60 arranged at the edge of the mounting plate 10. A locking cylinder three 62 is arranged on the support plate 60. A positioning plate 230 is arranged on the third connecting plate 23. A positioning hole 231 is arranged on the positioning plate 230. The locking cylinder three 62 and the positioning hole 231 cooperate with each other. A rotating frame 63 is rotatably installed in the support plate 60. A telescopic motor 64 is arranged on the rotating frame 63. A connecting disk two 65 is arranged at the end of the telescopic motor 64. A mating head 66 is arranged on the connecting disk two 65. A connecting disk one 251 is arranged on the second L-shaped frame 25. A mating hole 252 is arranged at the position corresponding to the mating head 66 on the connecting disk one 251.

A tension spring is arranged between the support slider 68 and the arc-shaped groove 67. The support slider 68 is in contact installation with the edge of the rotating frame 63.

[0045] Specifically, the third connecting plate 23 is installed between the guide rail 50 through the support wheel 58. When the sand box positioning assembly 2 is adjusted to the horizontal state, the third connecting plate 23 is first locked through the positioning plate 230, the positioning hole 231 and the locking cylinder three 62, thereby locking the state of the third connecting plate 23, which is convenient for the subsequent turning and demoulding mechanism 4 to drive the box body 200 to turn. Through the cooperation and locking of the connecting disk two 65 and the mating head 66 with the connecting disk one 251 and the mating hole 252 on the second L-shaped frame 25, when the turning and demoulding mechanism 4 turns, it will drive the rotating frame 63 to rotate synchronously, wherein the rotation axis of the rotating frame 63 coincides with the axis of the output shaft of the turning motor 40. After the sand box is turned by ninety degrees, the first L-shaped frame 24 is controlled to move by combining with the adjusting cylinder 26, so as to separate the upper sand box and the lower sand box, realize the separation of the box body 200, and further complete the subsequent demoulding and moulding sand collection operations.

[0046] Further, as Figure 2 , Figure 4 , Figure 8As shown, a positioning probe 201 is provided on the first connecting plate 20, a positioning receiver 61 is provided on the support plate 60 at a height corresponding to that of the positioning probe 201, a locking cylinder 37 is provided at the end of the linkage plate 35, and a locking hole 21 is provided on the first connecting plate 20 at a position corresponding to the locking cylinder 37.

[0047] Specifically, the setting of the positioning probe 201 and the positioning receiver 61 facilitates controlling the sand box positioning assembly 2 to be in a horizontal state. At the same time, the setting of the locking cylinder 37 and the locking hole 21 facilitates locking the horizontal state, ensuring the overall stability of the sand box positioning assembly 2 during the subsequent movement of the flipping and demolding mechanism 4.

[0048] A casting process of a high-pressure pump alloy pump shell casting system as described above includes the following steps: S1. Adjust the first connecting plate 20, the second connecting plate 22, and the third connecting plate 23 to a vertical state through the lifting drive mechanism 3, and position and lock the mating rod 57 at the end of the third connecting plate 23 through the lower swing positioning assembly 5; S2. Place the box body 200 on the upper side of the second L-shaped frame 25, and control the first L-shaped frame 24 to press on the upper side of the box body 200 by combining the adjusting cylinder 26, and start casting the box body 200; S3. After pouring is completed and cooling is done, release the locking of the end of the third connecting plate 23 by the lower swing positioning assembly 5, control the first connecting plate 20, the second connecting plate 22, and the third connecting plate 23 to adjust to a horizontal state along the guide rail 50 through the lifting drive mechanism 3, and connect the ends of the third connecting plate 23 and the second L-shaped frame 25 through the edge connecting mechanism 6; S4. Control the first L-shaped frame 24 and the second L-shaped frame 25 to flip through the flipping and demolding mechanism 4, and then drive the second L-shaped frame 25 to separate from the first L-shaped frame 24 by combining the telescopic motor 64 with synchronous flipping to complete demolding.

[0049] The working principle of the embodiment of the present invention is: As Figure 1 - Figure 9 shown, first drive the sand box positioning assembly 2 to a vertical state through the lifting drive mechanism 3, and lock the end of the third connecting plate 23 by combining the lower swing positioning assembly 5 to ensure the overall stability of the sand box positioning assembly 2 and ensure the safety and reliability of the subsequent casting process. Install the fabricated box body 200 on the first L-shaped frame 24 and the second L-shaped frame 25 respectively, control the upper sand box and the lower sand box to be accurately docked through the adjusting cylinder 26, and then perform the casting operation on the box body 200. After pouring is completed and fully cooled, release the locking of the third connecting plate 23 by the lower swing positioning assembly 5, control the sand box positioning assembly 2 to adjust to a horizontal state through the lifting drive mechanism 3, connect the third connecting plate 23 and the second L-shaped frame 25 through the edge connecting mechanism 6. At this time, control the box body 200 to flip by 90 degrees through the flipping and demolding mechanism 4, transfer the box body 200 to the upper side of the receiving plate 11, and control the upper sand box and the lower sand box to separate by using the adjusting cylinder 26 to achieve mold splitting and subsequent demolding treatment.
