Description

Technical Field

[0001] This utility model relates to the field of sand box cleaning technology, specifically a sand box for easy cleaning used in casting. Background Technology

[0002] A sand box is a frame used to hold and fix molding sand in the casting process. It is one of the core tools of sand casting. Its core function is to provide a cavity for the casting to be formed. Currently, casting generally involves coating a paraffin model with a similar size and shape to the casting with refractory coating and drying it. Then, it is buried in dry quartz sand and vibrated to shape it. Under negative pressure, the liquid metal is poured in, causing the model to vaporize and occupy its position. After solidification and cooling, the casting is formed. After the sand pouring step, the sand box used for casting needs to be cleaned of the residual sand inside.

[0003] A search revealed a Chinese patent for a sand box that is easy to clean for casting, publication number CN212350304U. The sand box includes a box body, a support mechanism at the bottom of the box body, a bottom heat dissipation mechanism at the bottom of the box body, a side heat dissipation mechanism on the side of the box body, and a water inlet mechanism at the top of the box body.

[0004] The aforementioned sand box has a drain outlet on the top cover of the water inlet mechanism, which facilitates the discharge of sand from the sand box when pouring sand for casting. Water inlet pipes are fixedly connected to both ends of the top cover, allowing clean water from the outside to enter the sand box for casting. Spray nozzles fixedly connected to the bottom of the water inlet pipes facilitate the spraying of water to flush the sand in the sand box, making it easy to clean the sand in the dead corners of the sand box and prevent sand residue from affecting the quality of the sand box in the next use. However, its structure is relatively simple, and it only uses water flow for rinsing. When it encounters highly viscous resin sand, if the nozzle is not aimed at the area being rinsed, the resin sand is easy to remain in the sand box, resulting in poor cleaning effect. In addition, it only uses a single nozzle to spray water for rinsing, and it takes a long time to completely flush down the sand remaining on the inner wall of the sand box, resulting in low cleaning efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a sand box for casting that is easy to clean, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A sand box for easy cleaning in casting includes a sand box body, a number of lifting hooks are hinged to the upper part of the outer ring of the sand box body, a heat dissipation cavity is provided inside the sand box body, and side heat dissipation pipes adapted to the heat dissipation cavity are provided through both sides of the sand box body. Vibration motors are installed on the lower part of both sides of the sand box body by means of mounting screws and anti-loosening nuts. The top of the sand box body is provided with a feed inlet at the center. Several valve pipes are provided on both sides of the top of the feed inlet. The end of the valve pipe that extends into the sand box body is provided with an anti-clogging nozzle. The valve pipes on the same side are grouped together. The top of each group of valve pipes is connected to a cleaning water pipe. The end of the cleaning water pipe away from the valve pipe is connected to a connecting pipe.

[0007] Preferably, a number of dust blowing pipes are provided at the top of the sand box body near both sides, and the end of the dust blowing pipe that extends into the sand box body is provided with an anti-clogging net, and the position of the dust blowing pipe is adapted to the inner wall of the sand box body.

[0008] Preferably, a buffer spring is fixedly installed at the bottom corner of the sand box body, and an anti-slip seat is connected to the bottom of the buffer spring, and an anti-slip rubber pad is attached to the bottom of the anti-slip seat.

[0009] Preferably, the bottom end of the sand box body, near the corner and below each buffer spring, is detachably mounted with a support block via connecting bolts.

[0010] Preferably, when the threads of the connecting bolts are screwed to their limit, the bottom ends of the plurality of support blocks are on the same horizontal plane, and the bottom surface of the support blocks is provided with anti-slip texture.

[0011] Preferably, the vibration motor is detachably connected to the sand box body via mounting bolts and anti-loosening nuts, and a lifting ring is provided in the center of the side of the vibration motor away from the sand box body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a vibrating motor, valve pipe, cleaning water pipe, and sand box body working together. When the sand box body is filled with resin sand, the vibrating motor can be activated. The continuous vibration generated by the vibrating motor, combined with water flow rinsing, can dislodge residual sand from the sand box body, making it easier to clean the highly adhesive resin sand and improving the cleaning effect.

[0013] By setting up buffer springs, anti-slip seats, and support blocks in conjunction with a vibration motor, the elastic support of the buffer springs and anti-slip seats can buffer the impact load on the supporting ground, reducing the probability of damage. Furthermore, by connecting the dust blowing pipe to an external high-pressure air pipe, gas can be sprayed onto the side wall of the sand box body, further improving the cleaning effect of residual casting sand inside the sand box body and increasing cleaning efficiency.

[0016] 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. Example

[0017] Combination Figures 1-3 A sand box for easy cleaning in casting includes a sand box body 1. Several lifting hooks 2 are hinged to the upper part of the outer ring of the sand box body 1. A heat dissipation cavity is provided inside the sand box body 1. Side heat dissipation pipes 3 that are adapted to match the heat dissipation cavity are provided through both sides of the sand box body 1. Vibration motors 5 are installed on the lower part of both sides of the sand box body 1 by means of mounting screws and anti-loosening nuts.

[0018] See Figure 2 and Figure 3 Furthermore, a feed inlet 4 is provided at the center of the top of the sand box body 1. Several valve pipes 8 are provided on both sides of the top of the feed inlet 4. One end of the valve pipe 8 that extends into the sand box body 1 is provided with an anti-clogging nozzle 9. The valve pipes 8 on the same side are grouped together. The top of each group of valve pipes 8 is connected to a cleaning water pipe 7. The end of the cleaning water pipe 7 away from the valve pipe 8 is connected to a connecting pipe 10. The vibration motor 5 is detachably connected to the sand box body 1 by mounting bolts and anti-loosening nuts. A lifting ring is provided at the center of the side of the vibration motor 5 away from the sand box body 1.

[0019] Specifically, the side heat dissipation pipe 3 is set to improve the heat dissipation effect of the sand box body 1. When it is necessary to clean the sand in the sand box body 1, the sand box body 1 can be rotated according to the existing technology so that most of the sand can be poured out from the feed port 4. When pouring out the sand, the connecting pipe 10 can be connected to the water supply pipe of the external water pump as needed, and the valve pipe 8 can be opened as needed. At this time, the cleaning water can be delivered to the anti-clogging nozzle 9 through the transmission of the cleaning water pipe 7 and the connecting pipe 10 to spray out, so as to rinse the inside of the sand box body 1. The rinsing method can improve the cleaning effect and reduce the probability of sand residue. When the sand inside the sand box body 1 is resin sand or other highly viscous sand, the vibration motor 5 can be started in advance before the rinsing. The vibration motor 5 can continuously generate vibration to shake off the residual sand in the sand box body 1. During subsequent rinsing, it can prevent most of the highly viscous sand such as resin sand from sticking to the side wall of the sand box body 1, so as to improve the cleaning effect. Example

[0020] See Figure 3 Furthermore, based on Embodiment 1, several dust-blowing pipes 6 are provided at the top and sides of the sand box body 1. One end of the dust-blowing pipe 6 extending into the sand box body 1 is provided with an anti-clogging mesh, and the position of the dust-blowing pipe 6 is adapted to match the inner wall of the sand box body 1. Buffer spring components 11 are fixedly installed at the bottom corner of the sand box body 1. The bottom end of the buffer spring component 11 is connected to an anti-slip seat 12, and the bottom end of the anti-slip seat 12 is attached with an anti-slip rubber pad. Support blocks 13 are detachably installed at the bottom corner of the sand box body 1 and below each buffer spring component 11 via connecting bolts 14. When the threads of the connecting bolts 14 are tightened to the limit, the bottom ends of several support blocks 13 are on the same horizontal plane, and the bottom surface of the support blocks 13 is provided with anti-slip texture.

[0021] Specifically, during or after cleaning, the dust blowing pipe 6 can be connected to an external high-pressure air pipe as needed. Subsequently, the high-pressure airflow can be delivered to the dust blowing pipe 6 by opening the air valve. Since the dust blowing pipe 6 is attached to the side wall of the sand box body 1, the residual sand adhering to the side wall of the sand box body 1 can be blown off by the airflow to eliminate cleaning dead corners. When the vibration motor 5 is started, the connecting bolt 14 can be unscrewed as needed. Then the support block 13 can be removed from under the anti-slip seat 12. At this time, the elasticity of the buffer spring 11 can be released. When the sand box body 1 is placed horizontally, it can play an elastic support role to reduce the impact force of the vibration motor 5 during vibration, thereby reducing the impact load on the supported ground and reducing the probability of damage to the ground or support platform.

[0022] In actual operation, the side heat dissipation pipe 3 is set to improve the heat dissipation effect of the sand box body 1. When it is necessary to clean the sand in the sand box body 1, the sand box body 1 can be rotated according to the existing technology so that most of the sand can be poured out from the feed port 4. When pouring out the sand, the connecting pipe 10 can be connected to the water supply pipe of the external water pump as needed, and the valve pipe 8 can be opened as needed. At this time, the cleaning water can be delivered to the anti-clogging nozzle 9 through the transmission of the cleaning water pipe 7 and the connecting pipe 10 to spray out, so as to rinse the inside of the sand box body 1. The rinsing method can improve the cleaning effect and reduce the probability of sand residue. When the sand inside the sand box body 1 is highly viscous sand such as resin sand, the vibration motor 5 can be started in advance before the rinsing. The vibration motor 5 can continuously generate vibration to shake off the residual sand inside the sand box body 1. During subsequent rinsing, it can prevent most of the highly viscous sand such as resin sand from sticking to the side wall of the sand box body 1, so as to improve the cleaning effect. During or after cleaning, the dust blowing pipe 6 can be connected to an external high-pressure air pipe as needed. Subsequently, the high-pressure airflow can be delivered to the dust blowing pipe 6 by opening the air valve. Since the dust blowing pipe 6 is attached to the side wall of the sand box body 1, the residual sand adhering to the side wall of the sand box body 1 can be blown off by the airflow to eliminate cleaning dead corners. When the vibratory motor 5 is started, the connecting bolt 14 can be unscrewed as needed. Then the support block 13 can be removed from under the anti-slip seat 12. At this time, the elasticity of the buffer spring 11 can be released. When the sand box body 1 is placed horizontally, the anti-slip seat 12 and the buffer spring 11 contact the support platform, which can play an elastic support role to reduce the impact force when the vibratory motor 5 vibrates, thereby reducing the impact load on the supported ground and reducing the probability of damage to the ground or support platform. Furthermore, the display and control components and modules used in the aforementioned vibration motor 5 and external water pump are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
