An intelligent casting platform for impeller casting

Abstract

The present invention belongs to the technical field of impeller casting, and specifically relates to an intelligent casting platform for impeller casting, which includes a base plate, a lower mold, an upper mold, a middle mold, a lower stripper plate and a split mold sleeve. In the process of driving the casting product to be demolded from the middle mold by moving the lower stripper plate upward, the sliding frame at the top of the split mold sleeve and the fixed block at the bottom fix the middle mold and the lower mold together, so that the casting product can be easily separated from the middle mold, thereby realizing the demolding of the casting product from the middle mold. As the lower stripper plate moves upward, the fixed block is separated from the contact with the bottom of the lower mold, so that the lower mold is separated from the middle mold. Since the top block in the middle of the split mold sleeve abuts against the lower concave platform, as the lower stripper plate continues to move upward, the synchronous block drives the side plate to move upward synchronously, and through the contact between the top block and the lower concave platform, the lower stripper plate moves upward to drive the split mold sleeve and the middle mold to move upward, so that the middle mold is separated from the lower mold. At this time, the upper mold, the middle mold and the lower mold are separated to different heights, thereby facilitating the demolding of the casting product and the cleaning of the mold.

Description

Technical Field

[0001] The invention belongs to the technical field of impeller casting, and in particular relates to an intelligent casting platform for impeller casting. Background Art

[0002] The impeller of a submersible pump is a special water pump impeller, which is usually designed with a mixed flow structure to adapt to the characteristics of liquid flow in oil wells. The intelligent casting platform for impellers is a system that integrates advanced manufacturing technologies to improve the efficiency and quality of the casting process.

[0003] In the prior art, the impeller casting requires the use of an upper mold, a middle mold and a lower mold, and a cavity area, i.e., a casting cavity, is formed between the three to form the outline of the impeller. A pouring port is provided on the top surface of the upper mold, extending from the top of the upper mold to the upper end of the casting cavity. During the installation process of the mold, the lower mold is used as the base mold, the middle mold is directly connected to the lower mold, and finally the upper mold and the lower mold are molded together. Since the middle mold is directly installed on the lower mold, the middle mold and the casting block are not easy to separate during the mold opening process, and the shape and structure of the casting block are often destroyed. There are corresponding treatment schemes in the prior art, such as the Chinese patent with publication number: CN208528027U, which mainly fixes and welds the middle mold and the lower mold, and separates the casting from the second demolding rod by installing a second demolding rod on the top of the middle mold. The above scheme has the following problems: Since the middle mold and the lower mold are fixedly welded, the casting cavities of the middle mold and the lower mold cannot be cleaned after each demolding, which affects the quality of the casting.

[0008] A retractable fixed block is installed at the bottom of the side plate, the fixed block abuts against the bottom of the lower mold, and a synchronous block is installed at the bottom of the lower stripper plate. When the synchronous block contacts the side plate, the fixed block contracts, and the fixed block is separated from the contact with the bottom of the lower mold.

[0009] As a further optimization or improvement of this solution, a slide groove is provided at the bottom of the side panel, and the fixed block is slidably installed in the slide groove. A plug is installed at one end of the fixed block close to the lower stripping plate, and the fixed block is connected to the inner wall of the slide groove through a spring. A slot is provided at the bottom of the lower stripping plate, and the plug is inserted into the slot.

The lower stripping plate and the upper stripping plate are respectively installed with rack plates in opposite directions, and the lower stripping plate and the upper stripping plate are meshed with the gear through the rack plates.

[0012] As a further optimization or improvement of the present solution, the upper stripping plate is in an inverted L-shape, and the top end of the upper stripping plate is in pressing contact with the stripping module.

[0013] As a further optimization or improvement of this solution, the stripping module is connected to the bottom of the upper mold through spring 2, and the bottom of the stripping module is flush with the bottom of the upper mold.

[0016] Beneficial effects of the present invention:

[0017] (1) In the process of demolding the casting from the middle mold by moving the lower demolding plate upward, the sliding frame at the top of the mold splitting sleeve and the fixed block at the bottom fix the middle mold and the lower mold together, so that the casting can be easily separated from the middle mold, thereby realizing demolding of the casting from the middle mold.

[0018] As the lower stripper plate moves upward, the spring rebounds and drives the plug to be inserted into the slot. At this time, the fixed block disengages from the bottom of the lower die, separating the lower die from the middle die. Since the top block in the middle of the splitter sleeve abuts against the lower concave platform, as the lower stripper plate continues to move upward, the synchronous block drives the side plates to move upward synchronously. Through the contact between the top block and the lower concave platform, the lower stripper plate moves upward, driving the splitter sleeve and the middle die to move upward, separating the middle die from the lower die. At this time, the upper die, middle die and lower die are separated to different heights, thereby facilitating the demoulding of the casting and cleaning of the mold.

[0019] (2) The lower stripper plate and the upper stripper plate of the present invention are connected by gears. When the lower stripper plate moves upward, the rack plate on the lower stripper plate drives the gear to rotate, and the rotation of the gear can drive the upper stripper plate to move downward. When the lower stripper plate drives the upper mold to move upward, the casting is separated from the middle mold. The lower stripper plate moves upward and drives the upper stripper plate downward at the same time, so that the top of the upper stripper plate presses the stripper module. When the pressure block groove presses the stripper module, the stripper module moves downward, so that the casting is separated from the upper mold, thereby realizing automatic demolding of the casting. The present invention drives the lower stripper plate to move upward to realize step-by-step demolding of the casting from the middle mold and the upper mold, thereby improving the demolding efficiency of the equipment and the yield rate of the casting.

[0034] See also Figure 1-Figure 11 , an intelligent casting platform for impeller casting, comprising a base plate 1, a lower die 2, an upper die 3 and a middle die 4, the lower die 2 is mounted on the base plate 1, the middle die 4 is mounted in the lower die 2, the upper die 3 cooperates with the lower die 2 in opening and closing, a demoulding assembly 5 is mounted on the middle die 4, a pouring port 31 is provided at the top of the upper die 3, the pouring port 31 is connected to the casting cavity 8, a cylinder 6 is mounted on the base plate 1, and an output end of the cylinder 6 is connected to a lower demoulding plate 51;

[0035] The middle mold 4 includes an edge platform 41, an upper concave platform 42 and a lower concave platform 43. The edge platform 41 is installed on the circumference of the middle mold 4. The upper and lower ends of the edge platform 41 are respectively provided with an upper concave platform 42 and a lower concave platform 43. The middle mold 4 is provided with a lower plate groove 44. The lower plate groove 44 vertically penetrates the middle mold 4 and the lower mold 2, and the lower plate groove 44 is respectively connected with the upper concave platform 42 and the lower concave platform 43. The lower plate groove 44 is provided with mold sleeve grooves 441 on both sides.

[0036] The demoulding assembly 5 comprises a lower demoulding plate 51 and a mold splitting sleeve 54. The mold splitting sleeve 54 is composed of a sliding frame 541 and a side plate 542. The side plate 542 is slidably matched with the mold sleeve groove 441, and the side plate 542 abuts against the upper concave platform 42. The lower demoulding plate 51 is inserted into the sliding frame 541 and slidably matched with the lower plate groove 44. A top block 547 is installed on the side plate 542, and the top block 547 abuts against the lower concave platform 43.

[0037] A retractable fixed block 543 is installed at the bottom of the side plate 542, and the fixed block 543 abuts against the bottom of the lower mold 2. A synchronization block 512 is installed at the bottom of the lower stripping plate 51. When the synchronization block 512 contacts the side plate 542, the fixed block 543 contracts, and at this time the fixed block 543 is out of contact with the bottom of the lower mold 2.

[0038] Specifically, a slide groove 546 is provided at the bottom of the side plate 542, and the fixed block 543 is slidably installed in the slide groove 546. A plug 545 is installed at one end of the fixed block 543 close to the lower stripping plate 51. The fixed block 543 is connected to the inner wall of the slide groove 546 through a spring 544. A slot 511 is provided at the bottom of the lower stripping plate 51, and the plug 545 is inserted into the slot 511. A synchronization block 512 is installed at the bottom of the lower stripping plate 51, and the synchronization block 512 abuts against the side plate 542.

[0039] It should be noted that, in the initial state, the plug 545 abuts against the side wall of the lower stripper plate 51, and the spring 1 544 is in a stretched state. At this time, one end of the fixed block 543 is ejected out of the slide groove 546, and the ejected slide groove 546 abuts against the bottom of the lower mold 2. The edge platform 41, the upper concave platform 42 and the lower concave platform 43 on the middle mold 4 are located outside the casting cavity 8, and the casting liquid will be formed in the casting cavity 8.

[0040] It should be noted that see Figure 6-Figure 9 , the lower stripper plate 51 is inserted into the parting sleeve 54 through the sliding frame 541, and the lower stripper plate 51 and the parting sleeve 54 slide together. In the mold closing state, the top sliding frame 541 of the parting sleeve 54 abuts against the upper concave platform 42, the top block 547 in the middle of the parting sleeve 54 abuts against the lower concave platform 43, and the fixing block 543 at the bottom of the parting sleeve 54 abuts against the bottom of the lower mold 2. The parting sleeve 54 fixes the middle mold 4 and the lower mold 2 together as a whole; when opening the mold, start the cylinder 6 to drive the lower stripper plate 51 to move upward. During the upward movement of the lower stripper plate 51, the top of the lower stripper plate 51 pushes the upper mold 3 to move upward, so that the casting is separated from the middle mold 4. Since the parting sleeve 54 fixes the middle mold 4 on the lower mold 2, the casting can be easily separated from the middle mold 4. See Fig.11 As the lower stripper plate 51 moves upward, the spring 544 rebounds and drives the plug 545 to be inserted into the slot 511. At this time, the fixed block 543 is out of contact with the bottom of the lower mold 2. At this time, the lower mold 2 is separated from the middle mold 4. As the lower stripper plate 51 continues to move upward, the synchronization block 512 drives the side plate 542 to move upward synchronously, and contacts the lower concave platform 43 through the top block 547. The lower stripper plate 51 moves upward and drives the parting sleeve 54 and the middle mold 4 to move upward, so that the middle mold 4 is separated from the lower mold 2. At this time, the upper mold 3, the middle mold 4 and the lower mold 2 are separated and located at different heights, thereby facilitating the demoulding of the casting and cleaning of the mold.

[0041] See also Figure 4-Figure 6The upper mold 3 has a pressing block groove 32 at the bottom, and the edge platform 41 has an upper plate groove 45, which vertically passes through the middle mold 4 and the lower mold 2, and is connected to the pressing block groove 32, and a retractable stripping module 33 is installed in the pressing block groove 32;

[0042] An upper stripper plate 52 is slidably installed in the upper plate groove 45 , and a gear 53 is rotatably installed in the lower die 2 . Rack plates 55 with opposite directions are respectively installed on the lower stripper plate 51 and the upper stripper plate 52 , and the lower stripper plate 51 and the upper stripper plate 52 are meshed with the gear 53 through the rack plates 55 .

[0043] Specifically, the upper stripper plate 52 is in an inverted L-shape, and the top end of the upper stripper plate 52 is in press contact with the stripper module 33 .

[0044] It should be noted that the lower stripper plate 51 and the upper stripper plate 52 are connected by a gear 53. When the lower stripper plate 51 moves upward, the rack plate 55 on the lower stripper plate 51 drives the gear 53 to rotate, and the rotation of the gear 53 can drive the upper stripper plate 52 to move downward. When the lower stripper plate 51 drives the upper mold 3 to move upward, the casting is separated from the middle mold 4. When the lower stripper plate 51 moves upward, it drives the upper stripper plate 52 to move downward, so that one end of the upper stripper plate 52 passes through the block groove 32 to press the stripper module 33. When the block groove 32 presses the stripper module 33, the stripper module 33 moves downward, so that the casting is separated from the upper mold 3, and the casting is automatically demolded.

[0045] See also Figure 4-Figure 5 The stripping module 33 is connected to the bottom of the upper mold 3 through a spring 2 34 , and the bottom of the stripping module 33 is flush with the bottom of the upper mold 3 .

[0046] It should be noted that when the stripping module 33 is in action, the casting liquid is prevented from entering the briquetting groove 32 to ensure the demoulding efficiency of the upper stripping plate 52. The bottom of the stripping module 33 is flush with the bottom of the upper mold 3 to avoid major defects in the appearance of the casting due to the stripping module 33. After the casting liquid enters the casting cavity 8, a high temperature and high pressure environment is formed inside the casting cavity 8. At this time, the stripping module 33 will be pressed upward by the internal high pressure, so that a bulge is formed in the area near the stripping module 33 on the final molded casting. There is no need to worry about the bulge on the casting. The bulge will be polished off during the subsequent lathe polishing, and it will not affect the final output of the casting.

[0047] See also Figure 2 The demoulding components 5 are symmetrically arranged in multiple groups, and the output end of the cylinder 6 is connected to the lower demoulding plate 51 through a connecting rod 7. It should be noted that the cylinder 6 is connected to an automatic controller, and the lifting height of the cylinder 6 is controlled by the control panel of the automatic controller to realize the automatic lifting and lowering of the cylinder 6. The control principle and control method of the cylinder 6 belong to the existing technology in the field of intelligent casting, and this scheme will not be repeated.

[0048] Specifically, an upper mold plate is installed on the outer side of the upper mold 3, and a lower mold plate is installed on the outer side of the lower mold 2. It should be noted that when the upper mold 3 and the lower mold 2 are actually installed, an upper mold plate and a lower mold plate will be installed on the outer sides of the upper mold 3 and the lower mold 2 respectively.

[0049] The implementation principle of the present invention is:

[0050] In the mold closing state, the top sliding frame 541 of the mold splitting sleeve 54 abuts against the upper concave platform 42, the top block 547 in the middle of the mold splitting sleeve 54 abuts against the lower concave platform 43, and the fixed block 543 at the bottom of the mold splitting sleeve 54 abuts against the bottom of the lower mold 2. The mold splitting sleeve 54 as a whole fixes the middle mold 4 and the lower mold 2 together.

[0051] When the mold is opened, the cylinder 6 drives the lower stripper plate 51 to move upward. During the upward movement of the lower stripper plate 51, the top of the lower stripper plate 51 pushes the upper mold 3 to move upward, so that the casting is separated from the middle mold 4. As the lower stripper plate 51 moves upward, the rack plate 55 on the lower stripper plate 51 drives the gear 53 to rotate. The rotation of the gear 53 can drive the upper stripper plate 52 to move downward, so that the top of the upper stripper plate 52 presses the stripper module 33. When the pressure block groove 32 presses the stripper module 33, the stripper module 33 moves downward, so that the casting is separated from the upper mold 3, thereby realizing automatic demoulding of the casting.

[0052] As the lower stripper plate 51 moves upward, spring 1 544 rebounds and drives the plug 545 to be inserted into the slot 511. At this time, the fixed block 543 disengages from the bottom contact with the lower mold 2. At this time, the lower mold 2 is separated from the middle mold 4. As the lower stripper plate 51 continues to move upward, the synchronization block 512 drives the side plate 542 to move upward synchronously, and contacts the lower concave platform 43 through the top block 547. The lower stripper plate 51 moves upward, drives the parting sleeve 54 and the middle mold 4 to move upward, so that the middle mold 4 is separated from the lower mold 2. At this time, the upper mold 3, the middle mold 4 and the lower mold 2 are separated and located at different heights, thereby facilitating the demolding of the casting and cleaning of the mold.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
