[0030] The present invention has the following beneficial effects:

[0031] 1. For the casting demoulding device for agricultural machinery equipment, after the casting is cooled, the electric slider moves above the water tank. At this time, the first vertical rod is directly below the second through hole. The second air cylinder controls the punch to separate it from the die cavity. Then, the third air cylinder is used to move the first vertical rod upward. The first vertical rod slides through the second through hole, and the top of the first vertical rod abuts against the inclined surface of the slider. The slider drives the abutting rod to eject the casting, and then the casting directly falls into the water tank. This process does not require manual participation, effectively reducing the labor cost.

[0032] 2. For the casting demoulding device for agricultural machinery equipment, before demoulding, the punch moves to one side under the drive of the second air cylinder. At this time, the dial plate abuts against the first cross plate, and the moving plate moves away from the falling point of the casting. The first compression spring compresses and stores energy. After demoulding, the electric slider moves, and the dial plate moves away from the first cross plate. The moving plate moves towards the casting under the action of the first compression spring. At the same time, the first brush heads contact the upper surface of the casting, and the first brush heads automatically clean the casting, increasing the practicability of the device;

[0033] Moreover, the first brush plate is set as an L-shaped plate, and the second positioning rod slidably penetrates through the first brush plate. A fourth compression spring is sleeved on the second positioning rod. One end of the fourth compression spring abuts against the fixed plate, and the other end of the fourth compression spring abuts against the first brush plate. A plurality of first convex blocks are equidistantly installed at the top end of the clamping plate, and a second convex block is installed at one end of the first brush plate. The second convex block is in sliding contact with the first convex block. When the first brush plate moves, under the combined action of the first convex block and the fourth compression spring, the first brush plate performs a reciprocating motion, increasing the cleaning effect on the casting and further increasing the practicability of the device.

[0034] 3. For the casting demoulding device for the agricultural machinery equipment, a blanking port is opened at the bottom of the water tank, and a baffle is hinged at the bottom of the mounting seat. Under normal conditions, the baffle closes the blanking port under the action of the second torsion spring. After the casting is cleaned, the moving plate pushes the casting to the blanking port through the second cross plate. The casting abuts against the baffle, and the baffle opens. The second cross plate pushes the casting out of the water tank, thus realizing the automatic blanking function of the casting, eliminating the need for manual fishing of the casting from the water tank and further reducing the labor cost.

[0035] In addition, after the casting is blanked, the first vertical rod moves downward, driving the second vertical rod to move downward. The limiting block abuts against the baffle, causing the baffle to rotate and close the blanking port. Then the baffle abuts against one end of the second cross plate, driving the moving plate to reset. The device waits for the next casting for automatic cleaning and automatic blanking, ensuring the repeatability of the working cycle of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0049] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that when demolding a casting for an existing agricultural machinery equipment, the operator uses a clip to remove the casting from the mold and then transfers the casting to clean water. This process requires manual participation, thus increasing the labor cost of casting. Please refer to Figures 1 to 11, A demoulding device for casting parts of agricultural machinery equipment, including a gantry bracket 101. An electric slider 102 is installed on the gantry bracket 101. A first cylinder 103 is installed at the bottom end of the electric slider 102. An installation bracket 104 is installed on the piston rod of the first cylinder 103. A punch 106 is installed on the installation bracket 104. A die 107 is also installed on the installation bracket 104. A second cylinder 105 is installed at one end of the installation bracket 104. The piston rod of the second cylinder 105 is fixedly connected to the punch 106.

[0050] Among them, a hollow cavity 109 is arranged inside the die 107. A slider 108 is slidably installed in the hollow cavity 109. A contact rod 115 is installed at one end of the slider 108. A first through hole 113 is opened on the die 107. The contact rod 115 is slidably installed in the first through hole 113. A second compression spring 110 is installed on the slider 108. One end of the second compression spring 110 abuts against the die 107. A water tank bracket 401 is arranged below the gantry bracket 101. A water tank 201 is installed on the water tank bracket 401. During demoulding, the punch 106 and the die 107 are located directly above the water tank 201. The slider 108 drives the contact rod 115 to eject the casting part, and the casting part falls into the water tank 201.

[0051] Specifically, a second through hole 116 is also opened at the bottom end of the die 107. The second through hole 116 communicates with the hollow cavity 109. The cross-section of the slider 108 is trapezoidal. An installation seat 114 is arranged inside the water tank 201. A third cylinder 112 is installed on the installation seat 114. The top end of the piston rod of the third cylinder 112 is installed with a first vertical rod 111. During demoulding, the top end of the first vertical rod 111 is located directly below the second through hole 116. The first vertical rod 111 moves upward. The first vertical rod 111 slidably penetrates through the second through hole 116. The top end of the first vertical rod 111 abuts against the inclined surface of the slider 108. The slider 108 drives the contact rod 115 to eject the casting part.

[0052] In this embodiment: After the casting part is cooled, the electric slider 102 moves above the water tank 201. At this time, the first vertical rod 111 is located directly below the second through hole 116. The second cylinder 105 controls the punch 106 to separate it from the die 107. Then, the third cylinder 112 is used to make the first vertical rod 111 move upward. The first vertical rod 111 slidably penetrates through the second through hole 116. The top end of the first vertical rod 111 abuts against the inclined surface of the slider 108. The slider 108 drives the contact rod 115 to eject the casting part. Then the casting part directly falls into the water tank 201. When discharging, the workpiece directly falls into the water. On the one hand, the water can buffer the workpiece during the falling process. On the other hand, after the discharging is completed, the workpiece can be directly cleaned, saving the transportation process and the process. This process does not require manual participation and effectively reduces the labor cost.

[0053] Example 2. This example aims to facilitate the solution of the problem of automatically cleaning castings. This example is an improvement based on Example 1. Specifically, please refer to Figures 1 to 11 , a cleaning mechanism 200 is provided in the water tank 201. The cleaning mechanism 200 includes a moving plate 206.

The dial plate 202 intermittently abuts against the first cross plate 203. When the moving plate 206 reaches the maximum displacement, the dial plate 202 rotates against the elastic force of the first torsion spring 209. After the dial plate 202 is separated from the first cross plate 203, the dial plate 202 resets under the action of the first torsion spring 209.

[0054] Before demoulding, the ejector die 106 moves to one side driven by the second cylinder 105. The dial plate 202 abuts against the first cross plate 203. The moving plate 206 moves in the direction away from the landing point of the casting. The first compression spring 205 compresses and stores energy. After demoulding, the moving plate 206 moves towards the casting under the action of the first compression spring 205.

The second convex block 308 is in sliding contact with the first convex block 307.

[0058] In this embodiment: Before demoulding, the punch 106 moves to one side driven by the second cylinder 105. At this time, the dial plate 202 abuts against the first cross plate 203, and the moving plate 206 moves in the direction away from the falling point of the casting.

The moving plate 206 moves towards the casting under the action of the first compression spring 205. At the same time, the first brush head 208 contacts the upper surface of the casting, and the first brush head 208 automatically cleans the casting, increasing the practicability of the device;

[0059] Moreover, the first brush plate 207 is arranged as an L-shaped plate, and the second positioning rod 311 slidably penetrates through the first brush plate 207.
