Description

Technical Field

[0001] This invention relates to the field of casting technology, specifically to a casting equipment for aluminum alloy water-cooled motor housings. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and the mold making is simple, it is suitable for single-piece production, batch production, and mass production of castings. For a long time, it has been a basic process in casting production.

[0003] For sand casting, a significant issue is the large amount of dust generated during the molding and cleaning stages.

[0004] Relevant data shows that dust is generated in various processes during casting, including sand grinding, molding, pouring molten iron, deburring, and other steps. In the process of casting without melting, approximately 50 kg of dust is generated for every ton of workpieces cast. Among these, the sand molding process, which requires a large amount of casting sand, generates a significant amount of dust. Although exhaust fans are installed in the production workshop, dust is scattered throughout the workshop, and the exhaust fans can only effectively remove dust near the fan, not the dust closer to the ground.

[0005] If this dust is allowed to drift freely in the production workshop, on the one hand, it will lead to a dirty and messy environment in the workshop. This is because most foundry workshops are relatively enclosed, and when a large amount of dust accumulates, it will affect the machinery and equipment in the entire production workshop. On the other hand, a large amount of dust will not only directly invade people's lungs, but also cause a large amount of skin tissue to stick together, threatening human health.

[0006] In order to effectively remove these dust particles, an aluminum alloy water-cooled motor housing casting equipment is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide an aluminum alloy water-cooled motor housing casting equipment. By using a dust removal device, when the isolation cover is placed on the workbench, the dust removal device is activated and removes a large amount of sand and dust generated during the molding and cleaning stages of the casting process, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A casting equipment for aluminum alloy water-cooled motor housings, comprising:

[0010] Base, columns, and worktable;

[0011] A column is fixedly installed on the base, and a workbench is fixedly installed on the side of the column, with the workbench located in the middle of the column.

[0012] Also includes:

[0013] A dust removal device is installed on the column. When the dust removal device is placed on the workbench, it is activated and removes a large amount of sand and dust generated during the molding and cleaning stages of the casting process.

[0014] The top of the isolation cover is equipped with a vacuum pipe, which is connected to an air pump. The vacuum pipe is used to remove dust, and the isolation cover has a through hole for connecting to the vacuum pipe.

[0015] It is worth noting that without a dust removal device, even if the isolation cover isolates the workbench from the outside world, the large amount of dust generated during the molding and cleaning stages cannot be removed and will remain inside the isolation cover. This not only affects the workers' vision, but also leads to operational errors and injuries during hammering or compaction because they cannot see what is inside the isolation cover. Furthermore, because a large amount of dust cannot be removed, the dust remaining inside the isolation cover will disperse throughout the production workshop after the isolation cover is opened, which will eventually harm the workers' respiratory system. Therefore, installing a dust removal device can effectively remove the large amount of dust generated during the molding and cleaning stages. By using a vacuum pipe to remove the dust from inside the isolation cover, visibility inside the isolation cover can be improved, and the harm of dust emissions to human health and the environment can be reduced.

[0016] It is worth noting that, in order to prevent the dust removal device from sucking away most of the air inside the isolation hood during the absorption process, thus reducing the airflow inside the hood and consequently reducing the mobility of the dust so that it cannot be quickly removed by the dust removal device, two air inlets are fixedly installed on the side of the isolation hood. The air inlets are equipped with air inlet covers, and the air inlets have guide plates that act as guides. In order to prevent dust from drifting out along the air inlets, the air inlets of the guide plates are installed facing the top of the isolation hood. This can effectively prevent the dust from falling out, and also allow the air inside the isolation hood to carry the dust from bottom to top to the dust suction pipe, thereby improving the working efficiency of the dust removal device.

[0017] Preferably, the conveying device includes a sand storage box fixedly installed at the top of a column. The sand storage box has two cavities of different sizes, which are sloping grooves. The bottom of the sloping grooves in the sand storage box has a feed inlet. A sand box gate is installed at the top of each of the two feed inlets. A discharge channel is opened inside the column. One end of the discharge channel is fixedly installed on the feed inlet. The discharge channel is fixedly installed inside the column. The other end of the discharge channel is connected to the discharge outlet. A sand pipe is installed at the other end of the discharge outlet. A sand nozzle is fixedly installed at the end of the sand pipe away from the discharge outlet. A gate switch is fixedly installed on the sand nozzle. A through hole is opened at the top of the isolation cover for the sand pipe to extend into the isolation cover.

[0018] It is worth noting that, in order to ensure that the large amount of dust generated during the molding and cleaning stages can be removed, this invention concentrates the processes of pouring casting sand and sprinkling sand on the parting surface within an isolation hood. When the isolation hood is placed on the workbench, the dust removal device is activated, and the gate inside the sand storage box is energized. When casting sand is needed, the conveying device is used to transport the molding sand or talc powder from the sand storage box into the isolation hood. The principle is as follows: the operator presses the gate switch on the sand nozzle, and the sand box gate at the bottom of the funnel in the inner cavity of the sand storage box where the casting sand is stored... The door opens, and casting sand falls down the feed channel. When it falls into the sand box, it raises a lot of dust. At this time, the dust suction pipe connected to the air pump absorbs and removes the dust from the isolation hood. In addition, the talcum powder needed on the parting surface can be opened by the worker pressing the gate switch on another sand nozzle. The talcum powder in the inner cavity of the storage talcum powder falls into the palm of the worker's hand. The worker then sprinkles the talcum powder onto the parting surface. Dust will inevitably be generated during the powder sprinkling process. Similarly, the dust removal device in the isolation hood will remove this dust.

[0019] The sand box gate consists of a motor and a sand box gate. The motor is connected to the sand box gate through a lead screw. When the motor rotates, it drives the lead screw to rotate synchronously. The lead screw, along with the lead screw nut and the gate plate, reciprocates in the horizontal direction to open or close the gate.

[0020] It is worth noting that the casting sand and talc powder in the two inclined cavities of the sand storage box are transported to the isolation cover by a conveying device.

[0021] It is worth noting that the gate switch on the sand nozzle is connected to the sand tank gate inside the sand storage tank via an electric wire. The electric wire is wound around the sand pipe and extends to the sand storage tank gate. Pressing the gate switch opens the sand tank gate. In addition, the diameter of the through holes on the top of the isolation cover for connecting the sand pipe and the dust suction pipe is slightly smaller than the diameter of these three pipes, which can play a certain role in fixing them. Furthermore, brushes are installed at the through holes to prevent dust from escaping.

[0022] Preferably, the support device includes lifting lugs fixedly installed on the top of the isolation cover, and each of the two lifting lugs is equipped with a lifting rod, one end of which is fixedly installed on the top of the column.

[0023] It's worth noting that to prevent the isolation cover from being damaged by impact when it quickly falls onto the workbench, a lifting lug is fixedly installed on the top of the isolation cover. The lug is connected to the lifting rod via a hinge, and the lifting rod is a movable adjustable support rod that provides cushioning protection. After work is completed, the worker only needs to apply a slight upward force to lift the isolation cover. In addition, when the worker applies a downward force to the isolation cover, the movable adjustable support rod will act as a buffer when the isolation cover is about to touch the workbench, slowing down the descent of the isolation cover and allowing it to gently approach the workbench. Without the cushioning protection of the movable adjustable support rod and the sponge, if the worker makes large movements during operation to increase production efficiency, the isolation cover may inevitably be slammed onto the workbench, causing impact damage and deformation.

[0024] It is worth adding that the vacuum pipe and sand pipe inside the isolation cover are both corrugated pipes, and the foldable corrugated sheets along the folding and stretching direction can play a role in fixing the position and buffering. They can play a role in fixing the position after the isolation cover is opened and raised, and a role in buffering the process of the isolation cover being closed.

[0025] Preferably, the operating device includes operating windows fixedly installed on both sides of the observation window at an angle below. An elastic membrane is fixedly installed on the inner wall of the operating window. A hand guard is installed around the elastic membrane in an annular shape. A hand guard cylinder is installed inside the isolation cover with the hand guard.

[0026] It's worth noting that if only the hand guards are installed, a large amount of dust generated during the shaping and cleaning stages, even when workers don't put their hands inside the isolation enclosure through the operating window, will still drift out through it. Therefore, hand sleeves made of rubber are installed on the hand guards. When workers pull their hands out, the hand sleeves close due to the lack of external support and hang vertically, preventing dust from drifting out. In addition, brushes are installed on the hand guards to prevent dust from drifting out of the isolation enclosure. The brushes also have small balls at the top to prevent workers from being pricked by the sharp tips when they pull their hands out of the isolation enclosure.

[0027] Preferably, the collection device includes a groove formed on the workbench surface, a movable baffle is installed on the groove of the workbench surface, the movable baffle is installed on the workbench surface via a pivot, and a limit block and a lifting groove are fixedly installed on the side of the workbench near the movable baffle, and a collection frame is installed under the movable baffle.

[0028] It is worth noting that without a collection device, when workers scrape and mold the sand box, casting sand will fall onto the workbench. Because some of the sand particles used in the casting process are too large to be sucked up by the dust collection device, if the isolation cover is opened and a brush is used to clean it after work, a large amount of dust will be raised, which will harm people and the environment. At this time, workers can remove the tools on the center of the workbench, leaving the fallen casting sand. Then, workers can put their hands into the lifting groove to lift the two ends of the two movable baffles. The two movable baffles rotate around the pivot on the workbench, and the casting sand on the two movable baffles slides into the collection box. The small amount of dust raised during this process will also be removed by the dust removal device.

[0029] It is worth adding that when the movable baffle is lowered without using the collection device, the bottom of the baffle is supported by a pivot and a limit block to ensure that it is flush with the workbench surface and will not collapse.

[0030] Preferably, the starting device includes a housing fixedly installed on the outer wall of the isolation enclosure, and a push-button switch is fixedly installed at the bottom of the housing.

[0031] It is worth noting that, in order to avoid adding unnecessary work steps and reducing work efficiency, the equipment's starting device is fixedly installed on the outer shell of the isolation cover. When the isolation cover is on the workbench, the switch of the starting device is pressed, and the entire equipment is powered on and started; when the isolation cover is lifted, the switch is no longer pressed, and the entire equipment is powered off and stops working. This not only reduces the number of steps for workers to start the equipment, but also improves the workers' work efficiency.

[0032] Preferably, the protective device includes a spring with one end fixedly mounted inside the bottom of the housing, and the other end of the spring fixedly mounted on the bottom of the switch.

[0033] It is worth noting that without protective devices, if workers quickly lift or close the isolation cover to improve work efficiency, the excessive movement may cause the switch installed outside the isolation cover to be damaged by impact. Therefore, a spring is installed at the bottom of the switch. When the impact force is too great, and the pressure on the spring exceeds the support force that the spring can provide, the switch will retract into the housing, and the housing will withstand the remaining impact. After the impact force dissipates, the switch is pushed out by the spring and pressed onto the workbench to start the equipment. This can effectively prevent the switch from being damaged by a strong impact.

[0034] It is worth adding that an isolation material, which is a sponge, is fixedly installed on the bottom of the isolation cover. The sponge material can play a certain role in cushioning and protecting the isolation cover when it is closed, preventing dust and sand from falling out from the bottom of the isolation cover. It can also prevent the metal isolation cover from directly hitting the workpiece or the human body due to operational errors, thus preventing damage to the workpiece or the human body.

[0035] It is worth adding that the inner wall of the isolation cover is roughly funnel-shaped, similar to the large flat nozzle of a vacuum cleaner, which has a good effect on guiding dust. Due to the structure of the inner wall, during the suction process, the dust can be collected along the funnel-shaped inner wall to the vicinity of the suction pipe, which is conducive to the removal of dust.

[0036] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] 1. Dust removal device: When the isolation cover is placed on the workbench, the switch on the isolation cover is squeezed to start the device. At this time, the vacuum cleaner connected to the end of the suction pipe at the top of the isolation cover starts to work, and a large amount of dust generated by the workers working inside the isolation cover will be absorbed and removed.

[0038] 2. The sand pouring and powder spreading stages are concentrated inside the isolation hood. The casting sand and talc powder used in the sand pouring and powder spreading stages are stored in the sand storage box. The sand storage box is placed on top of the column. The bottom of the sand storage box is funnel-shaped. The bottom of the funnel is connected to one end of the discharge port through the discharge channel. The other end of the discharge port is connected to the sand pipe. The end of the sand pipe away from the discharge port is connected to the sand nozzle. When needed, simply press the gate switch on the sand nozzle to let the talc powder or casting sand fall from the sand nozzle for use. When it falls into the isolation hood, dust will inevitably be raised. At this time, the dust will be removed by the dust removal device inside the isolation hood.

[0039] 3. The starting device is a switch fixedly installed at the bottom of the back of the isolation cover. The equipment can only be powered on when the isolation cover is on the workbench. When the isolation cover is lifted off the workbench, the equipment is powered off and stops working. This self-starting switch not only reduces the work steps of production personnel and improves work efficiency, but also quickly disconnects the power supply to the equipment in case of an accident. A protective device is installed on the starting device. By setting a spring, when the starting device is accidentally hit onto the workbench, the spring acts as a buffer to protect the switch from damage. Attached Figure Description

Detailed Implementation

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0052] Example 1:

[0053] refer to Figures 1 to 10 This illustrates a first specific embodiment of the present invention.

[0054] The specific workflow is as follows:

[0055] As a preparation before installation, several points need to be explained in advance. First, the switch 901 used in the starting device is a push-button switch. Its working principle is that a continuous pressure needs to be applied to the switch 901 to power on all electrical appliances on the device. When the continuous pressure is removed, the device is powered off. Second, the brush on the hand ring 3022 is equipped with a small ball to prevent the worker's hand from being pricked by the tip of the brush when passing through the hand ring 3022.

[0056] Before operation: This invention needs to be installed. First, the base 1 is fixedly installed on the ground, and the column 2 is fixedly installed on the base 1. The column 2 is L-shaped, and a sand storage box 201 is fixedly installed on the top of the column 2. A workbench 4 is fixedly installed at a suitable height on the front of the column 2. This height is at waist height for the operator to operate. The two overhanging corners of the workbench 4 are supported by table legs, which are welded to the base 1 and the two overhanging corners of the workbench 4. The two separate sand boxes inside the sand storage box 201 are funnel-shaped, and the bottom of the funnel is fed by a feeding mechanism. A discharge port 202 is fixedly connected to one end of a discharge channel 203. A discharge port 204 is installed at the other end of the discharge channel 203. A sand pipe 7 is fixedly installed on the discharge port 204. The sand pipe 7 connects to the inside of the isolation cover 3, and a through hole is provided at the top of the isolation cover 3 for the sand pipe 7 to extend into. A sand nozzle 701 is fixedly installed at one end of the sand pipe 7 inside the isolation cover 3. A gate switch 702 is installed on the sand nozzle 701. A dust suction pipe 6 is fixedly installed on the top of the isolation cover 3, and a through hole is provided at the top of the isolation cover 3 for the dust suction pipe 6 to connect to the inside of the isolation cover 3. A lifting lug 3 is located at the bottom of the isolation cover 3. 03 is connected to the top of the column 2 via a hanging rod 8, and the isolation cover 3 is suspended on the workbench 4. An observation window 301, made of transparent glass, is fixedly installed on the front of the isolation cover 3. The operation window 302 is connected to the hand guard 3022 via an elastic membrane 3021, allowing the hand guard 3022 to move freely without damaging the elastic membrane 3021. A hand guard cylinder 3023 is fixedly installed on one side of the hand guard 3022 inside the isolation cover 3, and a brush is fixedly installed on the inner ring of the hand guard 3022, with a small ball mounted on the top of the brush. The workbench 4 is fixedly installed below... There is a collection box 5. Finally, air inlet covers 10 are fixedly installed on both sides of the isolation cover 3. A guide plate 1001 is installed inside the air inlet cover 10. The starting device is fixedly installed on the bottom back of the isolation cover 3, and a sponge is installed around the bottom edge of the isolation cover 3. The housing 902 of the starting device is fixedly installed on the isolation cover 3, and the bottom of the housing 902 is installed parallel to the bottom of the isolation cover 3. One end of the spring 903 is fixedly installed inside the bottom of the housing 902, and the other end of the spring 903 is installed at the bottom of the switch 901, and the switch 901 extends into the housing 902.

[0057] During operation, based on the above scheme, the general workflow of the equipment is as follows: the operator prepares the mixed casting sand and pours it into the sand storage box 201. The tools to be used are placed on the workbench 4, and then the isolation cover 3 is placed on the workbench 4. At the same time, the switch 901 installed on the outer wall of the isolation cover 3 comes into contact with the workbench 4 and is squeezed by the workbench 4. The switch 901 is turned on, and the dust removal device starts to work. The operator puts his hands into the isolation cover 3 through the operation window 302 to carry out the casting work. The operator can observe the casting operation through the observation window 301. During this process, the dust removal device continues to operate and absorbs and removes the dust generated by the casting operation inside the isolation cover 3. In order to prevent the isolation cover 3 from not fitting the workbench 4 properly, a ring of sponge is fixedly installed on the bottom wall of the isolation cover 3.

[0058] More specifically, the worker places the sand box, model, and necessary tools into the working area of ​​workbench 4. Then, the worker pulls down the isolation cover 3 to cover the workbench 4, and the collection frame 5 is installed at the bottom of workbench 4. When the isolation cover 3 is on the workbench 4, the equipment is powered on and the dust removal device is activated. When the worker needs casting sand, they can press the gate switch 702 on the sand nozzle 701. The gate switch 702 extends through an electric wire wound around the sand pipe 7 to the sand box gate 2 inside the sand storage box 201. 05. The bottom of the funnel storing casting sand in the sand storage box 201 is opened by the gate switch 702, and the casting sand falls down along the sand pipe 7. Similarly, when the staff needs to use talcum powder, they can press the gate switch 702 on another sand nozzle 701, and the talcum powder stored in the sand storage box 201 will fall into the staff's hands along the discharge channel 203 and the sand pipe 7. During this process, a lot of dust will inevitably be generated. At this time, the dust removal device that is always working will remove the dust floating in the isolation cover 3.

[0059] After work: The staff lifts and opens the isolation cover 3, carefully moves the sand box that has been molded away from the workbench 4, and then puts the isolation cover 3 back on the workbench 4. The dust removal device is restarted. The staff shakes the casting sand remaining on the wall of the sand pipe 7 onto the workbench 4 by hand. Then, they use brushes and other cleaning tools to sweep the dust on the workbench 4 and collect it on the movable baffle 401. The staff flips the movable baffle 401 and pours the dust on the movable baffle 401 into the collection box 5. At this time, a large amount of scattered dust will still be removed by the dust removal device.

[0060] Example 2:

[0061] The difference from Example 1 is:

[0062] When the switch 901 on the starting device is selected as a self-locking switch, although the self-locking switch will add an extra step of opening the switch 901, it can save the electricity cost of the dust removal device when the isolation cover 3 is needed and the dust removal device is not needed in certain situations.

[0063] It is worth noting that when using a self-locking switch as a starting device, production personnel need to manually open switch 901. At this time, switch 901 can be installed on the front or side of the isolation cover 3, which can prevent the isolation cover 3 from hitting the workbench 4 and causing impact damage to switch 901. Therefore, there is no need to install a protective device, thereby reducing manufacturing costs.

[0064] The above two embodiments are merely illustrative examples among the many embodiments of the present invention. Various variations can be made without departing from the principles of the present invention. Embodiments created by those skilled in the art through modifications to the present invention without creative effort are also within the scope of protection of the present invention.
