Description

Technical Field

[0001] This application relates to the field of rapid sand casting technology, and more specifically, to a rapid sand casting device for 3D printing of castings. Background Technology

[0002] 3D printing sand mold rapid casting equipment is a type of equipment that uses adhesive materials to bond sand and gravel to create molds. During the sand and gravel mold making process, the 3D printer lays sand and gravel layer by layer inside the box, which is one of the components of the 3D printing sand mold rapid casting equipment, until the sand and gravel form the required mold. Then the box is transported out to peel off the mold.

[0003] In some existing 3D printing sand mold rapid casting equipment, after the mold is made inside the box, the box is slid out of the equipment by sliding it out via a slide rail. After the box is moved out via the slide rail, the staff often need to move the box to the required position to separate the mold. However, since the box is quite heavy after the mold is made, it often requires multiple people to move the box, which is quite inconvenient.

[0004] To address the aforementioned issues, this application provides a rapid sand casting equipment for 3D printing of castings. Utility Model Content

[0023] Example:

[0024] This application discloses a rapid sand casting equipment for 3D printing of castings. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3The system includes a fixed housing 1, with four hydraulic push rods at its bottom for support. A printer body 2 is installed inside the fixed housing 1; the printer body 2 can be a conventional 3D printer, which will not be detailed here. Two translational sliding grooves 3 are provided on the inner wall of the bottom of the fixed housing 1. A printing box 4 is movably installed inside the fixed housing 1, containing hydraulic push rods and a printing plate. The printing plate is mounted on the top of the hydraulic push rods, facilitating the gradual downward movement of the printing plate during printing. A protrusion 7 is fixedly installed on the front face of the printing box 4, with through holes at both ends of the protrusion 7, and insert rods 8 are movably installed within these through holes. Two support components 10 are installed on the front and rear side walls of the printing box 4 to support its translational sliding. Two anti-tipping components 11 are installed at the bottom of the printing box 4 to prevent it from tipping over during movement. The support component 10 includes a fixing block 12, which is fixedly installed on the printing box 4. A lifting rod 13 is movably installed on the fixing block 12. A caster wheel 14 is connected to the bottom of the lifting rod 13, and a connecting plate 15 is connected to the top of the lifting rod 13. Two L-shaped mounting plates 16 are rotatably installed on the fixing block 12, and each L-shaped mounting plate 16 is equipped with a locking screw 17. During the process of pulling the printing box 4 out of the fixing box 1, the lifting rod 13 can be controlled to move downward until the connecting plate 15 is in contact with the top of the fixing block 12. The L-shaped mounting plate 16 can be controlled to rotate above the connecting plate 15, and the locking screw 17 can be controlled to pass through the L-shaped mounting plate 16 and connect to the connecting plate 15 to fix the position of the lifting rod 13.

[0025] Please see Figure 4The anti-tilt assembly 11 includes a fixed frame 18, which is fixedly installed at the bottom of the printing box 4. The width of the fixed frame 18 is the same as the width of the translation slide 3. A groove is provided at the bottom of the fixed frame 18, and a rotating shaft 19 is rotatably installed in the groove. A rotating plate 20 is fixedly connected to the outer wall of the rotating shaft 19, and a second universal wheel 21 is installed on the rotating plate 20. A limit plate 22 is also fixedly installed on the fixed frame 18. Two lifting slides 23 are provided on the side wall of the fixed frame 18 away from the limit plate 22. A lifting block 24 is slidably installed in each lifting slide 23. A threaded through hole is provided at the bottom of the lifting slide 23, and a screw is provided in the threaded through hole. The lifting block 24 is... The bottom end is provided with a threaded hole that matches the diameter of the screw. A limit block 26 is fixedly connected between the two lifting blocks 24. The top of the lifting block 24 is connected to the inner wall of the lifting slide 23 by a connecting spring 25. During the process of pulling the printing box 4 out of the fixed box 1 by rotating the rotating shaft 19, the rotating shaft 19 can be controlled to rotate, so that the rotating plate 20 rotates and the second universal wheel 21 is in contact with the ground. At this time, the connecting spring 25 pushes the lifting block 24 and the limit block 26 to move downward until the lifting block 24 is in contact with the inner wall of the bottom end of the lifting slide 23. The screw extends into the lifting slide 23 and connects to the lifting block 24, so that the limit block 26 and the limit plate 22 cooperate to limit the rotating plate 20.

[0026] Please see Figure 1 The top of the connecting plate 15 is provided with two threaded grooves, and the diameter of the threaded grooves is the same as the diameter of the locking screw 17, so as to facilitate the connection of the locking screw 17 to the connecting plate 15.

[0027] Please see Figure 1 The inner wall of the fixed box 1 is provided with a hidden slide groove, and a fixed rod 5 is fixedly installed in the hidden slide groove. A sliding baffle 6 is movably fitted on the outer wall of the fixed rod 5, and the sliding baffle 6 is movably fitted to the rear back side wall of the printing box 4. A positioning block 9 is also fixedly installed on the outer wall of the fixed rod 5, and the positioning block 9 is located in front of the sliding baffle 6. During the process of placing the printing box 4 into the fixed box 1, the printing box 4 pushes the sliding baffle 6 to move. When the sliding baffle 6 stops moving, it indicates that the printing box 4 has been installed in place. Then, the insertion rod 8 passes through the protrusion 7 and connects to the positioning block 9.

[0028] Please see Figure 1 The top of the positioning block 9 is provided with an insertion groove, and the diameter of the insertion groove is the same as the diameter of the insertion rod 8, which makes it easy to connect the positioning block 9 and the insertion rod 8 together.

[0029] The implementation principle of this embodiment is as follows: By controlling the two hydraulic push rods near the front end of the fixed box 1 to slowly retract, the insertion rod 8 moves upward and disengages from the connection with the positioning block 9, causing the printing box 4 to slowly slide out of the fixed box 1. During the sliding process, the universal wheel 14 near the front end of the printing box 4 first contacts the ground. The rotation of the rotating shaft 19 causes the rotating plate 20 to rotate, bringing the second universal wheel 21 into contact with the ground. At this time, the connecting spring 25 pushes the lifting block 24 and the limit block 26 downward until the lifting block 24 contacts the ground. The lowering groove 23 is inserted into the inner wall of the lowering groove 23 by a screw and connected to the lifting block 24. The limiting block 26 and the limiting plate 22 cooperate to clamp and fix the rotating plate 20. During the process of pulling the printing box 4 out of the fixed box 1, the hydraulic push rod slowly extends upward to reset and moves the four lifting rods 13 on the printing box 4 downward step by step so that the connecting plate 15 and the L-shaped mounting plate 16 are connected by the locking screw 17, so that the four universal wheels 14 contact the ground, and the printing box 4 is pulled out of the fixed box 1 smoothly and transferred.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
