Tray for 3D printing sand core and method for transferring 3D printing sand core

Abstract

The invention provides a supporting disc for 3D printing sand cores. The supporting disc is a steel part and is provided with a groove structure formed by a panel, a first side part and a second side part, wherein the first side part and the second side part are oppositely arranged at the same side of the panel; one side of the panel opposite to the first side part and the second side part is a flat surface; a plurality of through holes penetrating through the panel are formed on the panel; and along the direction from the first side part to the second side part, a penetrating port penetrating through the first side part and the second side part is formed. The supporting disc provided by the invention has the advantages that the whole process of taking the cores, transferring, preheating and drying the surfaces, removing sand, flow-coating, drying, assembling the cores, transferring core bags and filling modelings of the 3D printing sand cores with floor sand can be considered. The invention also provides a method for transferring the 3D printing sand cores. The method comprises the following steps of: in the whole procedures of taking the cores, transferring, preheating and drying the surfaces, removing sand, flow coating, drying, assembling the cores, transferring core bags and filling modelings of the 3D printing sand cores with floor sand, transferring the 3D printing sand cores, wherein the supporting disc is adopted without replacement all the time in the whole procedure.

Description

technical field [0001] The invention relates to a pallet for 3D printing sand cores and a method for transferring 3D printing sand cores. Background technique [0002] Flat tray is a kind of tooling commonly used in foundry workshops, and is often used to place, hold, transfer sand cores or other items. It is usually made of wood, plastic, and carbon steel. 3D printing technology is applied in the field of casting. Due to its characteristics of moldless casting, it is usually selected for the production of multi-variety and small-batch products. In addition, because the sand core coreless iron printed by a 3D printer based on 3DP technology , No core nose, and it needs to be dried with hot air before sand cleaning and after flow coating, so 3D printing sand cores can only be transported on pallets. For 3D printing, the entire casting process mainly includes: 3D printing, coring, transfer, pre-surface drying, sand cleaning, flow coating, drying, core assembly, core package ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the technical process of transferring 3D printing sand cores on ordinary pallets in the prior art to realize pre-surface drying, water-based paint flow coating drying, core assembly, core package transfer and other processes, it is necessary to continuously change pallets of different types (materials) or other tooling, The problem of low efficiency, the purpose of the present invention is to provide a tray for 3D printing sand cores, which can take into account the core taking, transfer, pre-surface drying, sand cleaning, flow coating, drying, and core assembly of 3D printing sand cores. , the whole process of core package transfer, molding back sand filling; also provide a method of transfer 3D printing sand core, in order to eliminate the defect that the prior art method of transferring 3D printing sand core needs to replace the pallet in the above whole process
