Description

Technical Field

[0001] The invention relates to the technical field of molding sand casting, in particular to a casting device for preventing sand casting and steel parts from sticking. Background Art

[0002] As a widely used metal casting process, sand casting has an industrial background that is closely related to the pursuit of manufacturing efficiency and low cost, meeting the needs of complex casting manufacturing, and adapting to the needs of sustainable development and environmental protection. Sand casting can quickly produce large quantities of metal castings, and is suitable for various types of metals and casting sizes at a relatively low cost. Sand casting is based on specific theoretical knowledge and technical principles. By pouring molten metal into the sand mold, the sand mold is used to maintain the shape of the model, and the casting is formed after the metal cools and solidifies. In this process, the sand casting device, as a key equipment, plays a vital role in the quality and production efficiency of the casting. With the continuous advancement of technology and the continuous development of the market, the sand casting casting device will continue to develop in the direction of intelligence, efficiency, and environmental protection, and make greater contributions to the transformation and upgrading and sustainable development of the foundry industry.

[0003] For example, a Chinese patent (publication number: CN117340207A) discloses a casting device, including a holding member, a tundish and a cooling roller. The holding member includes a receiving chamber and a control member, the control member is connected to the side wall of the receiving chamber, and is used to control the outflow speed of the alloy solution in the receiving chamber. The tundish is located on one side of the holding member.

[0004] On the other side, the cooling roller is located on the side of the tundish away from the containing part, and is used to cool the alloy solution. The alloy solution in the containing part flows through the tundish to the surface of the cooling roller. A measuring piece is provided on one side of the tundish to measure the weight of the tundish. The control piece is electrically connected to the measuring piece, and the outflow speed of the alloy solution is controlled according to the measurement result of the measuring piece. The casting device of the invention can accurately measure the weight of the tundish through the measuring piece, and the control piece controls the speed at which the alloy solution flows out of the containing cavity according to the measurement result of the measuring piece, so that the weight of the tundish remains stable, and the amount of alloy solution retained in the tundish can be kept stable, which is beneficial to improving the thickness uniformity of the alloy sheet after cooling.

[0039] In this embodiment, by cooperating with two impact mechanisms 2 and two stirring mechanisms 4, the falling speed of the molding sand can be accelerated, and the molding sand adhering to the surface of the workpiece can be caused to fall off. Under the joint action of the primary crushing mechanism 7, the secondary crushing mechanism 9 and the air intake mechanism 8, the molding sand can be quickly processed, which is convenient for the reuse of the molding sand.

[0040] Please refer again Figure 1 and Figures 7 to 8In order to realize the rapid recovery of molding sand, the primary crushing mechanism 7 in this embodiment includes a vibration seat 701 movably connected to the left side wall of the box body 1. The left and right side walls of the box body 1 are respectively provided with a clamping hole and a moving hole. The vibration seat 701 extends to the outside of the clamping hole. Limiting blocks are fixed on the upper and lower sides of the vibration seat 701. Four limiting bars are fixed on the inner side of the clamping hole. The four limiting bars are adapted to the two limiting blocks. Through the cooperation between the limiting bars and the limiting blocks, the vibration amplitude of the primary crushing mechanism 7 can be effectively avoided from being too large, thereby protecting the primary crushing mechanism 7. The bottom wall of the inner cavity of the vibration seat 701 is fixed with a vibration motor 702. The output shaft of the vibration motor 702 is fixed with an eccentric wheel. The eccentric wheel can generate great inertia when rotating, further ensuring the smooth vibration of the primary crushing mechanism 7. The right side wall of the vibration seat 701 is hinged with a sieve plate 703, and the sieve plate 703 is concave. The sieve plate 703 is set to be concave to ensure that the molding sand in the sieve plate 703 will not fly out during the vibration process, thereby improving the recovery effect of the molding sand.

A sealing cover 706 is fixed on the right side of the box body 1 and is adapted to the moving hole. The sealing cover 706 can prevent the molding sand from flying out and facilitate the removal of the workpiece.

[0041] In addition, the air intake mechanism 8 includes an outer shell 801 fixed to the left side wall of the box body 1, and the left side wall of the outer shell 801 is provided with multiple ventilation holes.

The active rod 902 is rotatably connected to the front side wall of the inner cavity of the box body 1 through a bearing. The front side wall of the inner cavity of the box body 1 is rotatably connected to a driven rod 903 through a bearing. The driven rod 903 penetrates to the outside of the rear side wall of the box body 1 and is rotatably connected to the rear side wall of the box body 1 through a bearing. The provision of the bearing can ensure the smooth rotation of the active rod 902 and the driven rod 903, and at the same time limit their positions, further promoting the smooth operation of the device. During operation, a driving gear 904 and a driven gear 905 are fixed to the outer surfaces of the active rod 902 and the driven rod 903 and are located at the rear side of the box body 1, respectively. The driving gear 904 is meshed with the driven gear 905. Through the mutual meshing of the driving gear 904 and the driven gear 905, it can be ensured that the driven rod 903 and the active rod 902 rotate in opposite directions, further prompting the two squeezing rollers 906 to run in opposite directions, ensuring the smooth crushing of the molding sand. Squeezing rollers 906 are fixed to the outer surfaces of the active rod 902 and the driven rod 903 and are located in the inner cavity of the box body 1.

[0043] In this embodiment, the continuous vibration of the primary crushing mechanism 7 can ensure that the workpiece dropped from the screen plate 703 is constantly vibrated, and the molding sand on its surface is further completely separated from the workpiece, thereby achieving the effect of preventing sand casting and cast steel parts from sticking. The combined action of the air intake mechanism 8 and the secondary crushing mechanism 9 can improve the recovery quality and efficiency of the molding sand.

[0044] It can be understood that, through the cooperation among the impact mechanism 2, the stirring mechanism 4 and the primary crushing mechanism 7, it is possible to ensure that the molding sand is smoothly separated from the surface of the workpiece. Through the cooperation among the air intake mechanism 8 and the secondary crushing mechanism 9, the recovery efficiency of the molding sand can be improved. The device can effectively prevent the molding sand from sticking to the surface of the workpiece, and at the same time facilitate the reuse of the molding sand, thereby improving the manufacturing efficiency of the workpiece.

[0045] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0046] The working principle of the above embodiment is:

[0047] (1) Place the sandbox on the stabilizing block 5 and pour the alloy solution into the casting hole. After the alloy solution cools down, start the two driving motors 202. The driving motors 202 drive the small gear 203 to rotate, further causing the sliding block 204 to slide. Since the trapezoidal block on the clamping block 2063 and the abutting block on the striking block 2051 abut against each other, the striking block 2051 remains stationary at this time. As the sliding block 204 continues to move, the block also continues to move, thereby compressing the compression spring 2054. When the block moves a certain distance, the block is The block will lift up the clamping block 2063. At this time, under the action of the compression spring 2054, the striking block 2051 will be ejected and hit the sand box. Under the repeated impact, the molding sand on the surface of the workpiece continues to fall off. At the same time, by controlling the stepping motor 401, the rotating gear 403 is driven to rotate, and the moving plate 404 is further driven to move. At the same time, the electric push rod is cooperated to adjust the height and horizontal position of the rotating device 406, and the micro motor 4063 is started to cause the drill bit 4065 to rotate, further accelerating the shedding of the molding sand in the sand box.

[0048] (2) When the molding sand in the sandbox falls off to a certain extent, the workpiece will also fall onto the sieve plate 703 together with the molding sand in the sandbox. Under the continuous vibration of the vibration motor 702, the molding sand adhering to the surface of the workpiece will be completely fallen off. At the same time, through the friction between the workpiece and the molding sand, the large pieces of molding sand can be turned into small pieces and fall to the bottom through the sieve plate 703. At this time, the control electric cylinder 705 can be moved to tilt the sieve plate 703, and the sealing cover 706 can be opened to remove the workpiece. If the workpiece is large, it can also be taken out from the top of the box body 1.

[0049] (3) The molding sand crushed by the primary crushing mechanism 7 will pass through the air intake mechanism 8. At this time, the fan 802 continuously draws external air into the box body 1 and sprays it out from the air outlet nozzle 803. The blown wind will drive other air in the box body 1 to move downward, further accelerating the falling of the small pieces of molding sand. At the same time, the power of the servo motor 901 passes through the driving gear 904 and the driven gear 905, further prompting the two squeezing rollers 906 to run synchronously, thereby squeezing and crushing the molding sand blocks, further forming fine sand and flowing out through the discharge rod. The device can effectively prevent the molding sand from sticking to the workpiece, and at the same time can process the molding sand, which is convenient for the reuse of the molding sand and can further improve the manufacturing efficiency of the workpiece.
