Description

Technical Field

[0001] This invention relates to the field of casting demolding technology, specifically to a high-efficiency demolding mold based on a negative pressure adsorption type agricultural vehicle connecting bracket casting. Background Technology

[0002] In the production of agricultural vehicles, the connecting bracket is a key component, typically used to support and connect the vehicle frame to other mechanical parts. To ensure the accuracy and strength of the connecting bracket, it is usually manufactured using a casting process. However, the demolding process of the connecting bracket has always been a critical issue in production. The quality of demolding directly affects subsequent processing techniques and product quality; therefore, efficient and precise demolding technology is key to improving casting efficiency and quality.

[0003] Existing methods for demolding connecting brackets mostly rely on traditional manual or semi-automatic methods. Specifically, existing technologies have the following significant drawbacks:

[0004] Most existing demolding equipment is either manually operated or semi-automated, requiring manual intervention during the demolding process. This wastes human resources and is prone to human error. Especially for complex-shaped connecting bracket components, manual demolding is inefficient and cannot guarantee demolding accuracy.

[0005] The connecting bracket has a complex shape during the casting process, and it often sticks to the mold. Traditional demolding methods cannot guarantee that the connecting bracket can be removed firmly and accurately, which may lead to deformation or damage during the removal process, affecting the accuracy of subsequent processing.

[0006] Because existing demolding methods rely on manual operation, workers are prone to fatigue during long-term, high-frequency operations, which can even lead to demolding accidents, increasing safety hazards and production risks.

[0007] Manual demolding is slow and cannot be mass-produced, resulting in stagnant production efficiency. As production scales up, traditional demolding methods become increasingly inefficient, severely impacting production cycles and overall capacity.

[0008] The above solutions present the following problems: Existing insulation devices may experience uneven heat distribution during the heating process of the insulation tank, failing to achieve uniform heating and insulation. This results in high energy consumption, increasing production costs over extended periods. Furthermore, they cannot achieve differentiated insulation and storage of various liquid raw materials, affecting the quality and stability of microbial agents.

[0009] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a high-efficiency demolding mold based on the casting of a negative pressure adsorption agricultural vehicle connecting bracket. Summary of the Invention

[0010] The purpose of this invention is to provide a high-efficiency demolding mold based on negative pressure adsorption agricultural vehicle connecting bracket casting, so as to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution:

[0012] A high-efficiency demolding mold technology based on negative pressure adsorption agricultural vehicle connecting bracket casting includes a base, on which a casting mold base is fixed, and a casting mold is assembled. A finished product box is provided next to the base. A frame is provided above the base, and a transverse frame is assembled on the frame. The transverse frame is equipped with a transverse motor, a transverse traveling gear, a transverse rack, a transverse slide, a transverse fixed guide rail, a transverse frame buffer, and a transverse frame anti-collision block. A lifting frame is assembled on the transverse frame, and the lifting frame includes a lifting motor, a lifting gear, a lifting motion rack, a lifting motion guide rail, and a lifting fixed slide. A demolding frame is fixed at the bottom of the lifting frame, and the demolding frame is equipped with a servo motor, a connecting rod plate, a traction rod, a clamping seat, a workpiece clamping block, an auxiliary pushing and clamping cylinder, a clamping seat guide rail, and a clamping seat slide. A suction cup frame is fixed at the bottom of the demolding frame, and several vacuum suction cups are assembled on the suction cup frame.

[0014] As a preferred technical solution, the lifting motion rack and lifting motion guide rail are vertically fixed on the lifting frame, the lifting motor is bolted to the transverse frame, and the output end is connected to the lifting gear key. The lifting gear meshes with the lifting motion rack to drive the lifting motion rack to move up and down. The lifting fixed slide is slidably engaged with the lifting motion guide rail, and the lifting frame slides up and down along the lifting fixed slide via the lifting motion guide rail.

[0015] As a preferred technical solution, the servo motor is bolted to the top center of the demolding frame, and its output end is fixed to the connecting rod plate. The connecting rod plate is hinged to the traction rod via a pin. The end of the traction rod away from the connecting rod plate is hinged to the clamping seat.

The clamping seat guide rail is horizontally fixed to the bottom of the demolding frame. The auxiliary push-clamping cylinder is bolted to the clamping seat, and its output end is welded to the workpiece clamping block.

[0016] As a preferred technical solution, the suction cup frame is a rectangular frame structure, which is fixed to the bottom of the clamping seat with bolts. Vacuum suction cups are evenly distributed on the bottom surface of the suction cup frame and are arranged to fit the contour of the workpiece. One end of the suction cup air pipe is threaded and sealed to the vacuum suction cup, and the other end is connected to the outlet of the vacuum pump unit through a flange after the flow converges. The vacuum pump unit is bolted to the top of the demolding frame.

[0017] As a preferred technical solution, the casting mold base is a metal welded bracket, which is fully welded to the base. The casting mold is positioned with the casting mold base by positioning pins and fixed with bolts that can be detached. The finished product box is an open metal box, which is fixed to the side of the base near the casting mold base by bracket bolts, corresponding to the transverse movement path of the transverse frame.

[0018] As a preferred technical solution, the workpiece clamping block is an arc-shaped metal block adapted to the shape of the agricultural vehicle connecting bracket, with an anti-slip and wear-resistant rubber pad bonded to the inner side. Several workpiece clamping blocks are symmetrically distributed on the clamping seat, without interfering with the distribution area of ​​the vacuum suction cup, forming an enclosed clamping structure.

[0020] Compared with existing technologies, the beneficial effects of this invention are as follows: Addressing the technical problems of low efficiency and large errors in manual and semi-automatic operations during the casting and demolding of traditional agricultural vehicle connecting brackets, including workpiece deformation and damage due to mold sticking, affecting processing accuracy, significant safety hazards during manual operation, and limitations in mass production and capacity, this invention achieves fully automated demolding through a composite structure of negative pressure adsorption and mechanical clamping, along with an automated transmission design. The entire process of demolding is integrated, with lateral movement, lifting, clamping, adsorption, demolding, and unloading all linked together without manual intervention, thus improving demolding efficiency and completely solving the problems of cumbersome and error-prone manual operations.

[0021] The entire process is automated, eliminating the need for operators to have close contact with high-temperature molds and workpieces, thus completely eliminating the risk of demolding accidents, significantly reducing production safety hazards, and improving the safety of production operations.

To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present invention by illustrating examples of the invention.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this invention provides a high-efficiency demolding mold technology solution for casting agricultural vehicle connecting brackets based on negative pressure adsorption: It includes a base 1, a casting mold base 11 fixed on the base 1, a casting mold 12 assembled on the casting mold base 11, and a finished product box 13 located beside the base 1; a frame 2 is located above the base 1, and a transverse frame 3 is assembled on the frame 2; the transverse frame 3 is equipped with a transverse motor 31, a transverse traveling gear 32, a transverse rack 33, a transverse slide 34, a transverse fixed guide rail 35, a transverse frame buffer 36, and a transverse frame anti-collision block 37; the transverse frame 3 is equipped with... The lifting frame 4 includes a lifting motor 41, a lifting gear 42, a lifting motion rack 43, a lifting motion guide rail 44, and a lifting fixed slide 45. A demolding frame 5 is fixed at the bottom of the lifting frame 4. The demolding frame 5 is equipped with a servo motor 51, a connecting rod disc 52, a traction rod 53, a clamping seat 54, a workpiece clamping block 55, an auxiliary pushing and clamping cylinder 56, a clamping seat guide rail 57, and a clamping seat slide 58. A suction cup frame 61 is fixed at the bottom of the demolding frame 5. Several vacuum suction cups 63 are mounted on the suction cup frame 61. The vacuum suction cups 63 are connected to the vacuum pump group 6 through suction cup air pipes 62.

[0032] The casting mold base 11 is fixedly connected to the base 1, and the casting mold 12 is assembled on the casting mold base 11; the transverse frame 3 is assembled on the frame 2; the lifting frame 4 is assembled on the transverse frame 3; the demolding frame 5 is fixed to the bottom of the lifting frame 4; the suction cup frame 61 is fixed to the bottom of the demolding frame 5; and the vacuum suction cup 63 is connected to the vacuum pump group 6 through the suction cup air pipe 62.

[0033] This structural design enables the entire demolding mold to perform multiple actions such as lateral movement, lifting, clamping, and adsorption, providing a foundation for efficient demolding. Through the coordinated work of various components, accurate demolding operations can be performed on the agricultural vehicle connecting bracket.

[0034] The transverse rack 33 is fixed parallel to the transverse fixed guide rail 35 on the top of the frame 2. The transverse motor 31 is bolted to the transverse slide 34 and its output end is keyed to the transverse traveling gear 32. The transverse traveling gear 32 meshes with the transverse rack 33. The transverse slide 34 is slidably engaged with the transverse fixed guide rail 35. The transverse frame buffer 36 and the transverse frame anti-collision block 37 are bolted to both ends of the frame 2 and are adapted to the ends of the transverse frame 3.

[0035] The transverse rack 33 and the transverse fixed guide rail 35 are fixed parallel to each other on the top of the frame 2; the transverse motor 31 is fixed to the transverse slide 34 by bolts, and its output end is connected to the transverse traveling gear 32 by a key. The transverse traveling gear 32 meshes with the transverse rack 33; the transverse slide 34 and the transverse fixed guide rail 35 are in sliding engagement; the transverse frame buffer 36 and the transverse frame anti-collision block 37 are fixed to both ends of the frame 2 by bolts.

[0036] When the transverse motor 31 starts, the transverse traveling gear 32 meshes with the transverse rack 33, driving the transverse slide 34 to slide on the transverse fixed guide rail 35, thereby realizing the transverse movement of the transverse frame 3. The transverse frame buffer 36 and the transverse frame anti-collision block 37 can prevent the transverse frame 3 from colliding with the end of the frame 2 during the transverse movement, thus playing a protective role.

[0037] The lifting motion rack 43 and the lifting motion guide rail 44 are vertically fixed on the lifting frame 4. The lifting motor 41 is bolted to the transverse frame 3, and its output end is keyed to the lifting gear 42. The lifting gear 42 meshes with the lifting motion rack 43, driving the lifting motion rack 43 to move up and down. The lifting fixed slide 45 is slidably engaged with the lifting motion guide rail 44, and the lifting frame 4 slides up and down along the lifting fixed slide 45 via the lifting motion guide rail 44.

[0038] The lifting motion rack 43 and the lifting motion guide rail 44 are vertically fixed on the lifting frame 4; the lifting motor 41 is fixed on the transverse frame 3 by bolts, and its output end is connected to the lifting gear 42 by a key, and the lifting gear 42 meshes with the lifting motion rack 43; the lifting fixed slide 45 is in sliding cooperation with the lifting motion guide rail 44.

[0039] When the lifting motor 41 is started, the lifting gear 42 meshes with the lifting rack 43, driving the lifting rack 43 to move up and down. This causes the lifting frame 4 to slide up and down along the lifting fixed slide block 45 via the lifting guide rail 44, thus realizing the lifting action of the demolding frame 5, which facilitates the demolding operation of the workpiece in the casting mold 12.

[0040] Servo motor 51 is bolted to the top center of demolding frame 5, and its output end is fixed to connecting rod plate 52. Connecting rod plate 52 is hinged to traction rod 53 through pin. The end of traction rod 53 away from connecting rod plate 52 is hinged to clamping seat 54. Clamping seat 54 is bolted to clamping seat slide 58. Clamping seat slide 58 is slidably engaged with clamping seat guide rail 57. Clamping seat guide rail 57 is horizontally fixed to the bottom of demolding frame 5. Auxiliary push clamping cylinder 56 is bolted to clamping seat 54, and its output end is welded to workpiece clamping block 55.

[0041] The servo motor 51 is fixed to the top center of the demolding frame 5 by bolts, and its output end is fixed to the connecting rod plate 52; the connecting rod plate 52 is hinged to the traction rod 53 by a pin; the other end of the traction rod 53 is hinged to the clamping seat 54; the clamping seat 54 is fixed to the clamping seat slide 58 by bolts, and the clamping seat slide 58 slides with the clamping seat guide rail 57; the auxiliary push-clamping cylinder 56 is fixed to the clamping seat 54 by bolts, and its output end is welded to the workpiece clamping block 55.

[0042] When the servo motor 51 starts, it drives the connecting rod disc 52 to rotate, which in turn drives the clamping seat 54 to slide on the clamping seat guide rail 57 via the traction rod 53, thereby enabling the workpiece clamping block 55 to open and close. The auxiliary push-clamping cylinder 56 can further push the workpiece clamping block 55 to enhance the clamping force and ensure a firm grip on the agricultural vehicle connecting bracket, facilitating subsequent demolding operations.

[0043] The suction cup frame 61 is a rectangular frame structure, which is fixed to the bottom of the clamp 54 with bolts. The vacuum suction cups 63 are evenly distributed on the bottom surface of the suction cup frame 61 and are arranged to fit the contour of the workpiece. One end of the suction cup air pipe 62 is threaded and sealed to the vacuum suction cup 63, and the other end is connected to the outlet of the vacuum pump group 6 through a flange after the flow is combined. The vacuum pump group 6 is bolted to the top of the demolding frame 5.

[0045] When the vacuum pump unit 6 is started, the vacuum suction cup 63 is generated by the suction cup air pipe 62, thereby adsorbing the agricultural vehicle connecting bracket. With the clamping of the workpiece clamping block 55, the workpiece is firmly fixed, making it easy to remove the workpiece from the casting mold 12.

[0046] The casting mold base 11 is a metal welded bracket, which is fully welded to the base 1. The casting mold 12 is positioned with the casting mold base 11 by positioning pins and is fixed by bolts that can be detached. The finished product box 13 is an open metal box, which is fixed to the side of the base 1 near the casting mold base 11 by bracket bolts, corresponding to the transverse movement path of the transverse frame 3.

[0047] The casting mold base 11 is fixed to the base 1 by full welding; the casting mold 12 is positioned to the casting mold base 11 by positioning pins and is detachably fixed by bolts; the finished product box 13 is fixed to the side of the base 1 near the casting mold base 11 by bracket bolts and corresponds to the transverse movement path of the transverse frame 3.

[0048] The full welding fixation between the casting mold base 11 and the base 1 ensures the stability of the structure; the detachable fixation of the casting mold 12 facilitates the replacement of molds of different specifications to adapt to different agricultural vehicle connecting brackets. The position setting of the finished product box 13 allows the transverse frame 3 to accurately place the demolded workpiece into the finished product box 13 during the transverse movement process, realizing automatic unloading.

[0049] The workpiece clamping block 55 is an arc-shaped metal block adapted to the shape of the agricultural vehicle connecting bracket. The inner side is bonded with an anti-slip and wear-resistant rubber pad. Several workpiece clamping blocks 55 are symmetrically distributed on the clamping base 54, without interfering with the distribution area of ​​the vacuum suction cup 63, forming an enclosed clamping structure.

It is symmetrically distributed on the clamping seat 54 and does not interfere with the distribution area of ​​the vacuum suction cup 63, forming an enclosed clamping structure.

[0051] The curved design of the connecting bracket, adapted to the shape of agricultural vehicles, allows for a better fit to the workpiece. The anti-slip and wear-resistant rubber pad on the inner side increases friction, preventing the workpiece from sliding or being damaged during clamping. The enclosed clamping structure can firmly clamp the workpiece from multiple directions, and combined with the adsorption effect of the vacuum suction cup 63, it improves the stability and reliability of demolding.

[0052] The transverse motor 31, lifting motor 41, servo motor 51, auxiliary push-clamp cylinder 56, and vacuum pump group 6 are all electrically connected to an external PLC controller through shielded wires to realize automated linkage control of transverse movement, lifting, clamping, adsorption, demolding, and unloading.
