Description

Technical Field

[0001] This utility model relates to the field of iron mold sand coating technology, specifically a molding machine for manufacturing sand molds. Background Technology

[0002] A molding machine is a device used to manufacture sand molds. When in use, a sand box is placed on the mold plate, and then molding sand is filled into the sand box. Then, the pressure plate on the molding machine is used to compact the molding sand inside the sand box so that the molding sand can be cast into the shape of the mold product. In order to keep the molding sand inside the sand box in a compacted state, an excess of molding sand is usually added to the sand box to make the pressure plate fully compact the molding sand. The excess molding sand will fall from the sides of the sand box during the compaction operation. At present, most molding machines lack a structure to collect excess molding sand. The molding sand that falls below the molding machine is inconvenient to collect, and the spilled molding sand cannot be recycled in time. Utility Model Content

[0003] The purpose of this invention is to provide a molding machine for manufacturing sand molds, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A molding machine for manufacturing sand molds includes: a base plate, a body fixed to the top of the base plate, and a pressure plate rotatably connected to the top of the body; Two support parts are arranged below the pressure plate. Each support part includes a carrier plate, and a clamp is rotatably connected to one side of the carrier plate. A mold plate is clamped and installed between two clamps, and a sand box is positioned on the top of the mold plate; Both support mechanisms are fixedly connected to the base plate, and the support mechanisms can adjust the position and height of the carrier plate; Two collection mechanisms are respectively fitted at both ends of the sand box to collect molding sand spilled from the periphery of the sand box. The collection mechanism includes a tray that is close to the sand box. An auger is rotatably connected inside the tray. A discharge pipe is fixedly connected to one end of the tray, and a motor that can drive the auger to rotate is fixed to the other end of the tray.

[0005] Furthermore, the top of the machine body is rotatably connected to a machine head seat, and the bottom of the machine head seat is fixed with a connecting column that is fixedly connected to the pressure plate.

[0006] Furthermore, the support mechanism includes an I-beam fixedly connected to the base plate, and a hydraulic cylinder capable of driving the carrier plate to move is fixed in the middle of the I-beam.

[0007] Furthermore, the inner bottom surface of the tray is inclined, and an arc-shaped cavity for accommodating the auger is opened at the bottom end of the inclined surface. A support rod that is fixedly connected to the base plate is fixed at the bottom of the tray.

[0008] Furthermore, a curved pipe is fixed to the outside of the support rod, and a hopper is fixed to the top of the curved pipe.

[0009] Furthermore, a panel is fixed to one side of the carrier plate, and the clamp includes an L-shaped plate rotatably connected to the panel, with a clamping plate detachably fixed to the top of the L-shaped plate.

[0010] Furthermore, both ends of the mold plate are fixed with connecting ears, which are clamped and fixed between the L-shaped plate and the clamping plate, and a motor capable of driving the L-shaped plate to rotate is fixed on the top of the carrier plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By attaching a tray to each end of the sand box, the two trays enclose the sand box. When excess molding sand falls from the open sand box, it can fall into the tray. Turning on the vibration motor on the tray causes the tray to vibrate. The vibration helps the molding sand inside the tray slide down the inclined surface of its bottom to the auger position. The motor drives the auger to rotate, which can directionally transport the collected excess molding sand out along the discharge pipe. This achieves convenient collection of excess molding sand for subsequent casting and, to a certain extent, prevents excess molding sand from being spilled on the ground.

[0012] 2. By fixing a vibration motor on the outside of the tray, the vibration motor causes the tray to vibrate, which facilitates the concentrated movement of the molding sand collected inside the tray towards the auger position. The vibration of the tray and the sand box also helps the pressure plate to compact the molding sand inside the sand box. At the same time, the two trays surrounding the sand box can further position and fix the sand box in the compaction position. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1, please refer to Figure 1 - Figure 4 In this embodiment of the present invention, a molding machine for manufacturing sand molds includes a base plate 100, a body 110 fixed to the top of the base plate 100, a pressure plate 111 rotatably connected to the top of the body 110, two support parts 200 arranged below the pressure plate 111, each support part 200 including a carrier plate 210, a clamp 220 rotatably connected to one side of the carrier plate 210, a mold plate 300 clamped and fixed between the two clamps 220, a sand box 310 detachably positioned and installed on the top of the mold plate 300, and the top surface of the base plate 100... Two support mechanisms 400 are fixedly connected. The support mechanism 400 is used to support the carrier plate 210. Both ends of the sand box 310 are equipped with collection mechanisms 500. The collection mechanism 500 can collect the molding sand spilled from the side of the sand box 310. The collection mechanism 500 includes a tray 510 that is close to the sand box 310. An auger 520 is rotatably connected inside the tray 510. One end of the tray 510 is connected to a discharge pipe 530 and the other end of the tray 510 is fixed with a motor 540 that can drive the auger 520 to rotate.

[0017] Specifically, by installing two trays 510 around the periphery of the traditional sand box 310, the trays 510 can collect excess molding sand falling from the opening of the sand box 310, thereby effectively preventing excess molding sand from falling onto the ground and polluting the casting environment. At the same time, the molding sand inside the trays 510 can slide to the position of the auger 520. The rotating auger 520 can directionally transport the molding sand out for recycling and reuse, keeping the casting environment clean and tidy while improving the utilization rate of molding sand.

[0018] like Figure 1 and Figure 2 As shown, in this embodiment, the top of the machine body 110 is rotatably connected to the machine head base 112, and the bottom of the machine head base 112 is fixed with a connecting column 1121. The connecting column 1121 is fixedly connected with the pressure plate 111. The machine head base 112 is fixed with a reduction motor that can drive the machine head base 112 to rotate with the pressure plate 111. When it is necessary to compact the molding sand in the sand box 310, the reduction motor drives the machine head base 112 to rotate, so that the pressure plate 111 moves to the top of the sand box 310 to compact the molding sand.

[0019] like Figure 4 As shown, in this embodiment, the support mechanism 400 includes a C-shaped beam 410 fixedly connected to the base plate 100. A hydraulic cylinder 420 is fixed in the middle of the C-shaped beam 410. The output end of the hydraulic cylinder 420 is fixed to the bottom surface of the carrier plate 210. Both ends of the C-shaped beam 410 are slidably connected to a positioning shaft 430. A carrier plate 210 is fixed at the top of the positioning shaft 430.

[0020] In this embodiment, the output end of the hydraulic cylinder 420 extends to move the carrier plate 210 upward. The two carrier plates 210 move upward together with the mold plate 300 and the sand box 310 through the clamp 220, so that the opening of the sand box 310 can be pressed into contact with the bottom surface of the pressure plate 111, thereby compacting the molding sand inside the sand box 310.

[0021] like Figure 2 and Figure 3 As shown, in this embodiment, the inner bottom surface of the tray 510 is a slope, and an arc-shaped cavity for accommodating the auger 520 is opened at the bottom end of the slope. A vibration motor 511 is fixed on the outside of the tray 510, and a shaft is fixed in the middle of the auger 520. One end of the shaft is rotatably inserted into the tray 510 and fixed to the output end of the motor 540. The other end of the shaft passes through the discharge pipe 530. A connecting rod 550 fixed to the tray 510 is provided above the discharge pipe 530. A connecting block 551 rotatably connected to the shaft is fixed at the bottom end of the connecting rod 550.

[0022] In this embodiment, when the pressure plate 111 compacts the open molding sand of the sand box 310, the excess molding sand will fall from the open of the sand box 310 into the tray 510. The vibration motor 511 vibrates the tray 510, causing the molding sand inside the tray 510 to slide down the inclined surface to the position of the auger 520. The rotation of the motor 540 and the auger 520 can directionally convey the molding sand to the discharge pipe 530.

[0023] like Figure 1 and Figure 3As shown, in this embodiment, a support rod 560 fixedly connected to the base plate 100 is fixed at the bottom of the tray 510, so that the tray 510 can be fixed around the sand box 310. A bent pipe 600 is fixed on the outside of the support rod 560, and a hopper 610 is fixedly connected to the top of the bent pipe 600. The hopper 610 facilitates the molding sand in the discharge pipe 530 to fall into the bent pipe 600. A container can be placed below the bent pipe 600 to facilitate the holding of molding sand.

[0024] In this embodiment, when it is necessary to remove the molded sand box 310 and molding sand, the pressure plate 111 is rotated away from the sand box 310, and the sand box 310 and molding sand can be lifted out by using an external hoisting tool connected to the hook on the sand box 310. Specifically, the product model 320 on the mold plate 300 inside the sand box 310, the hook (not shown in the figure), and the hoisting and removal of the sand box 310 are all existing technologies, and the specific details are not described in detail.

[0025] like Figure 4 As shown, in this embodiment, a panel 211 is fixed on one side of the carrier plate 210, and the clamp 220 includes an L-shaped plate 221 rotatably connected to the panel 211. A pressure plate 111 is detachably and slidably connected to the top of the L-shaped plate 221. Connecting ears are fixed at both ends of the mold plate 300. The connecting ears are clamped and fixed between the L-shaped plate 221 and the pressure plate 111. A motor 230 capable of driving the L-shaped plate 221 to rotate is fixed on the top of the carrier plate 210.

[0026] In this embodiment, when installing the mold plate 300, the connecting ears at both ends of the mold plate 300 are placed between the clamping plate 222 and the L-shaped plate 221. Then, the clamping plate 222 is fixed to the L-shaped plate 221 with bolts, so that the clamping plate 222 clamps and fixes the connecting ears on the fixture 220, thereby using the fixture 220 to clamp and fix the mold plate 300. After the sand box 310 is taken out, the motor 230 drives the fixture 220 to rotate 180 degrees, so that the mold plate 300 can present the other half of the product model 320 at the bottom. Then, the sand box 310 is again fitted onto the other half of the model on the mold plate 300 for secondary casting of molding sand. The above content is the existing technology of the molding machine, and the specific working principle will not be described in detail.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
