Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a 3D printed turnover box. Background Technology

[0002] A 3D printing sand handling box is an auxiliary tool used in the field of sand mold 3D printing, mainly for holding and transferring sand. In the sand mold 3D printing process, the sand handling box is a key auxiliary device to ensure production continuity. Its core function is to achieve standardized storage, efficient transfer and recycling of molding sand, which directly affects the stability and economy of the entire printing process. like Figure 1 As shown, there are still some problems in the practical application of current sand-pumping turnover boxes, which restrict production efficiency.

[0003] Firstly, the sand extraction efficiency is low. It takes about 4 hours to extract all the sand from a turnover box filled with molding sand. This time-consuming process can easily cause production disruptions and waiting, thus extending the overall production cycle. Secondly, pipe blockages occur frequently during sand pumping. Due to factors such as changes in humidity and uneven particle distribution during transportation, sand particles often accumulate and clog the pipes. This not only requires shutdown for cleaning but may also damage critical components such as the pump body due to sudden pressure increases, increasing equipment maintenance costs. Furthermore, the cost of manual monitoring is too high. Currently, the sand pumping process requires dedicated personnel to monitor the entire process. On the one hand, they need to monitor the sand pumping progress in real time to prevent the equipment from running idle after the molding sand has been extracted, thus avoiding energy waste and mechanical wear, and preventing excessively long pumping times. On the other hand, they need to be ready to deal with emergencies such as pipeline blockages. This method results in a waste of manpower and increases production costs. Utility Model Content

[0004] This invention provides a 3D printed turnover box to solve the technical problems in the prior art.

[0005] To solve the above problems, the 3D printed turnover box provided by this utility model adopts the following technical solution: a sand box, which is used to store sand; Also includes: Two-sided turnover boxes are set on the left and right sides of the sand box, and the turnover boxes are used to receive sand from the sand box; The bottom plate of the sand box is slidably assembled inside the sand box, and the bottom plate of the sand box can slide in the vertical direction inside the sand box. A lifting structure is provided below the sand box to drive the bottom plate to rise, so that the lifting structure drives the bottom plate to rise and quickly discharge the sand in the sand box into the turnover boxes on the left and right sides.

[0006] As a further improvement, the turnover box includes a box body and a protective step plate set on the top of the box body. The protective step plate is used to prevent people from falling. The protective step plate is evenly distributed with several through holes to ensure that sand enters the turnover box smoothly. The bottom of the box body is provided with a sand extraction port.

[0007] As a further improvement, the box is provided with an inclined surface for collecting sand, so that the sand is collected at the bottom of the box by gravity, so that the sand can be extracted.

[0008] As a further improvement, a vibration motor is fixedly installed on the side of the box to ensure that the sand falls smoothly.

[0009] As a further improvement, an air hole is provided on the sand extraction pipe between the sand extraction port and the external sand suction pump.

[0010] As a further improvement, a support frame for supporting the box is provided below the box.

[0011] As a further improvement, the bottom of the support frame is provided with leveling bolts for adjusting the height of the box.

[0012] As a further improvement, the lifting structure is a scissor-type lifting structure.

[0013] As a further improvement, the top of the sand box is equipped with baffles on both the front and rear sides. The two baffles block the sand in the front and rear directions, allowing the sand to flow into the turnover boxes on the left and right sides.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. The turnover boxes of the present invention are set on the left and right sides of the machine tool sand box. When in use, the bottom of the sand box is first lifted so that the sand flows into the turnover boxes on both sides. During this process, the sand suction pump can be started at the same time to extract the sand in the turnover boxes.

[0015] Using this method, the time to empty the sand box can be shortened to about 1 hour. After the sand box is emptied, preparations can be made for the next printing job, avoiding production interruptions caused by cleaning the turnover box separately, ensuring the continuity of production, and improving the operating efficiency of the equipment and the throughput of production.

[0016] During the printing process, fragmented time can be used to clean sand from the turnover box, optimizing the production process and making the entire production process more compact and efficient.

[0017] 2. The structure of this utility model is relatively simple, the manufacturing cost is relatively low, and the modification process requires no additional costs.

[0018] 3. This utility model opens air holes in the sand extraction pipe and small holes in easily blocked locations (such as bends in the pipe), so that the accumulated sand particles are loosened by the impact of airflow, reducing the possibility of blockage.

[0019] 4. After the improvement, the sand box of this utility model can be emptied in a faster time and there is basically no blockage. Therefore, there is no need to set up a separate person to guard it, which reduces labor costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] In existing technologies, sand extraction containers still have some problems in practical applications. First, the sand extraction efficiency is low; it takes about 4 hours to completely extract all the sand from a container filled with molding sand. This time-consuming process can easily cause production disruptions and waiting, extending the overall production cycle. Second, pipe blockages occur frequently during the sand extraction process. Due to factors such as humidity changes and uneven particle distribution during transportation, sand particles often accumulate and clog the pipes. This not only requires machine shutdown for cleaning but may also damage critical components such as the pump body due to sudden pressure increases, increasing equipment maintenance costs. Furthermore, the cost of manual monitoring is too high. Currently, a dedicated person needs to monitor the entire sand extraction process. On the one hand, they need to monitor the sand extraction progress in real time to prevent the equipment from running idle after the molding sand is extracted, avoiding energy waste and mechanical wear, and on the other hand, they need to be ready to deal with emergencies such as pipe blockages. This method results in wasted manpower and increased production costs.

[0024] To address the aforementioned issues, this invention incorporates two turnover boxes positioned on either side of the support rail. When cleaning sand from the machine tool's sandbox, the bottom of each turnover box can be lifted to divert the sand into the two larger boxes. Subsequently, the sand in the turnover boxes can be cleaned during spare moments, ensuring continuous production and improving equipment operating efficiency and throughput.

[0025] The vibratory motor prevents the sand pump from running dry, and the air vents in the sand pumping pipe prevent blockages and reduce equipment malfunctions. Since the sand box is emptied quickly and blockages are rare, no additional personnel are needed for monitoring, reducing labor costs.

[0026] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0027] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0028] Embodiment 1 of the 3D printed turnover box provided by this utility model: like Figure 2 and Figure 3 As shown, the 3D printed turnover box includes a sand box 2 for storing sand and two turnover boxes 1 respectively set on the left and right sides of the sand box 2. The turnover box 1 is used to receive sand from the sand box 2. The bottom plate of the sand box 2 is slidably fitted inside the sand box 2, and the bottom plate of the sand box 2 can slide vertically inside the sand box 2. A lifting structure (not shown in the figure) is provided below the sand box 2 to drive the bottom plate to rise, so that the lifting structure drives the bottom plate to rise and quickly discharge the sand in the sand box 2 into the turnover boxes 1 on the left and right sides. In this embodiment, the lifting structure is a scissor lifting structure.

[0029] The turnover box 1 includes a box body 102 and a protective step 101 disposed on the top of the box body 102. The box body 102 has an inclined surface for collecting sand, so that the sand is collected at the bottom of the box body 102 by gravity, so that the sand can be extracted. In this embodiment, the structure of the box body 102 is similar to a triangle. The protective step 101 is used to prevent people from falling. The protective step 101 has several through holes evenly distributed to ensure that the sand enters the turnover box 1 smoothly. The bottom of the box body 102 is provided with a sand extraction port 105.

[0030] A vibration motor 103 is fixedly installed on the side of the box 102 to prevent the sand from becoming dense and to ensure that the sand falls smoothly.

[0031] A support frame 104 is provided below the box body 102 to support the box body 102. The bottom of the support frame 104 is provided with leveling bolts for adjusting the height of the box body 102. The leveling bolts are mainly used to keep the turnover box 1 level. In addition, they can also adjust the height of the turnover box 1 as appropriate.

[0032] The sand box 2 has baffles 201 on both the front and back sides of the top. The two baffles 201 block the sand in the front and back direction, so that the sand flows into the turnover boxes 1 on the left and right sides.

[0033] In this embodiment, an air hole is provided on the sand extraction pipe between the sand extraction port 105 and the external sand suction pump. The air hole is located at a location prone to clogging (such as a bend in the pipe) to loosen the accumulated sand particles under the impact of the airflow and reduce the possibility of clogging. It should be noted that the air hole should not be too large to avoid affecting the extraction of sand.

[0034] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention.
