Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, specifically a horizontal gravity casting machine that can reduce the space occupied at the bottom. Background Technology

[0002] A casting machine is a piece of equipment used in industrial production, primarily for injecting molten metal, plastic, or other liquid substances into a mold to form the desired parts or products. Depending on the application and materials, casting machines can be categorized into various types, commonly including metal casting machines, plastic injection molding machines, and rubber injection machines. However, existing casting machines still have certain shortcomings in their use, such as…

[0003] Existing casting machines mainly use vertically mounted hydraulic cylinders to push the material formed in the mold out, which occupies a large amount of bottom space. In order to reduce the height of the mold, it is necessary to dig a foundation to bury part of the casting machine's base underground. In addition, the casting machine generates some fumes during the casting process, which is harmful to the physical and mental health of the workers. Most existing casting machines do not have a fume purification structure. Utility Model Content

The first top plate is slidably connected inside the limiting seat, and the top of the first top plate abuts against the second top plate. The second top plate slides through the inner wall of the base and is bolted to the bottom of the lower template.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This horizontal gravity casting machine, which reduces the space occupied at the bottom, pushes the first top plate to slide by activating the top core cylinder. The first top plate then pushes the second top plate and the lower template upward for demolding. By installing all the cylinders horizontally, the casting machine reduces the space occupied at the bottom. By activating the exhaust fan, the fumes generated during casting are drawn into a sealed box. Solid particles are removed by the water and filter screen inside the sealed box, and the remaining impurities are absorbed by the activated carbon plate before being discharged from the exhaust fan. This process purifies the fumes. The specific details are as follows:

[0016] 1. By activating the mold opening and closing cylinder, the core pulling template is pulled out from the mold, and the core is pulled from both sides. Then, the top core cylinder is activated to push the lower template upward to demold. All cylinders are installed horizontally to prevent the machine from having too little space at the bottom and needing to dig a foundation, thereby reducing the space occupied at the bottom of the casting machine.

[0017] 2. By starting the cylinder, the funnel is placed above the mold, the molten material is poured in, and then the exhaust fan is started to draw the flue gas generated during casting into the annular shell and send it into the sealed box. The solid particles are filtered out by the filter screen, the moisture is removed by the absorbent cotton, and the remaining impurities are absorbed by the activated carbon plate before being discharged. In this way, the casting machine purifies the flue gas. Attached Figure Description

[0026] In practice, the opening and closing mold cylinder 507 is activated to pull the side moving template 508 to slide along the slide bar 506, and the core pulling template 509 is pulled out from the mold 3 to perform core pulling on both sides. Then, the top core cylinder 502 is activated to push the first top plate 503 to slide. The first top plate 503 pushes the second top plate 504 and the lower template 4 to move upward to demold. All the cylinders are installed horizontally to reduce the space occupied at the bottom and prevent the need to dig a foundation due to the small space at the bottom of the machine.

[0027] See Figures 1-3It is known that the pushing mechanism 6 includes: a vertical plate 601, a support plate 602, a U-shaped plate 603, a cylinder 604, and a funnel 605. The vertical plate 601 is bolted to one side of the bed 1 and the base 2. The upper surface of the vertical plate 601 abuts against the support plate 602.

[0028] In practice, the cylinder 604 is activated to push the pallet 602 to move, which in turn causes the U-shaped plate 603 to slide within the vertical plate 601, placing the funnel 605 above the mold 3 to guide the flowing material and prevent it from splashing.

[0029] See Figures 1-5 It is known that the purification mechanism 7 includes: annular shell 701, riser 702, sealed box 703, exhaust fan 704, filter screen 705, drive motor 706, brush plate 707, absorbent cotton 708, and activated carbon plate 709. The upper surface and bottom of the support plate 602 are bolted to the annular shell 701. The two sets of annular shells 701 are connected by a pipe, and one side of the annular shell 701 is connected to the riser 702 by a pipe. One side of the riser 702 is connected to the sealed box 703. The upper part of the inner wall of the sealed box 703 is connected to the exhaust fan 704 by a pipe. The riser 702, sealed box 703, and exhaust fan 704 are all connected to the upper surface of the support plate 602. A filter screen 705 is slidably connected to the inner wall of the sealed box 703 via a support plate. A drive motor 706 is connected to the inner wall of the sealed box 703 above the filter screen 705 via a waterproof shell.

An activated carbon plate 709 is slidably connected to the inner wall of the sealed box 703 above the water-absorbing cotton 708 via a U-shaped piece.

[0030] In practice, the exhaust fan 704 is started to draw the flue gas generated during casting into the annular shell 701, which then enters the sealed box 703 through the riser 702. The solid particles are absorbed by the moisture in the sealed box 703, and then the solid particles are filtered out again by the filter screen 705. The moisture is then removed by the absorbent cotton 708, and the remaining impurities are absorbed by the activated carbon plate 709 before being discharged from the exhaust fan 704, thus purifying the flue gas of the casting machine.

[0031] In summary: When using this horizontal gravity casting machine that reduces bottom space occupation, firstly, the mold opening and closing cylinder 507 is activated to insert the core-pulling template 509 into the mold 3. Then, the top core cylinder 502 is activated to move the lower template 4 to the bottom. Water is added into the riser 702 and enters the sealed box 703. The molten metal raw material is poured into the funnel 605 and flows into the mold 3 to cool and solidify. During the pouring process, the generated fumes are drawn into the sealed box 703, filtered by water absorption and filter screen 705 to remove larger particles from the fumes. Then, the water absorbs moisture through absorbent cotton 708, and the activated carbon plate 709 absorbs the smoke. The remaining impurities in the air are discharged from the exhaust fan 704. The drive motor 706 is started periodically to drive the brush plate 707 to rotate and brush off the impurities attached to the filter screen 705. After the material in the mold 3 is formed, the cylinder 604 is started to move the annular shell 701 and the funnel 605 away from the top of the mold 3. Then the mold opening and closing cylinder 507 is started to pull the core pulling template 509 out of the mold 3. Then the top core cylinder 502 is started to push the lower template 4 upward and push the formed material out of the mold 3 a distance away. It is then clamped out by a clamp.
