Embodiment 1
[0041] Such as Figure 1 to Figure 7 As shown, this embodiment discloses a reinforcement method for 3D printing sand cores. The disclosed reinforcement method includes:
[0042] S1. For 3D printing sand cores with special structures, due to the special local structure, in order to prevent deformation, cracking and breaking during the process of operation, flow coating, assembly and pouring, this part of the sand core needs to be reinforced. In the design of the 3D printing sand core, the embedding hole that needs to place the core bone is reserved. The embedding hole is opened from the surface end of the 3D printing sand core that needs to strengthen the structure, passes through the main part of the 3D printing sand core and extends to the weak structural part. The position of the opening of the embedded hole should be avoided as far as possible from the surface of the sand core forming the casting, so as not to affect the surface quality of the casting. Since the core bone ...
Embodiment 2
[0063] This embodiment discloses a strengthening method for 3D printing sand cores, the disclosed strengthening method includes:
[0064] Steps S1 and S2 are the same as those in Example 1.
[0065] S3. Insert the core bone. The core bone is hollow tubular and made of metal material. There are a number of rubber-patting holes dislocated along the periphery of the core bone. Setting the rubber-patching holes in the misplaced position can meet the glue removal requirements and ensure the strength of the core bone.
[0066] S4. Glue injection, use the injection device to inject the casting binder into the core bone, use the extrusion device matched with the core bone to pass the adhesive in the core bone through the glue hole agent to the place between the embedding hole and the core bone Clearance. Of course, the injection device and the extrusion device can be one device, as long as both injection and extrusion can be realized.
[0067] Steps S5-S7 are the same as those in Ex...
