Shape-variable mold

Abstract

The invention provides a shape-variable mold, and relates to the technical field of molds. The shape-variable mold comprises a bottom plate and a plurality of sealing rods, and the side walls of the sealing rods abut against one another; one end of any sealing rod is provided with a telescopic rod for driving the sealing rod to move, and the other end of any sealing rod is a free end; and the telescopic rods are arranged on the bottom plate. According to the mold, a plurality of molds can be assembled together, and the free ends of the sealing rods of the two moulds abut against each other; and According to the size data of a model, the lengths of the telescopic rods are adjusted, the shortened lengths of the different telescopic rods are different, and then the outward moving distances of the sealing rods are different, so that a pouring cavity with the same size as the model is formed among the plurality of sealing rods, and raw materials can be poured into the pouring cavity, after the raw materials are solidified, the model with a fixed shape is formed, and therefore, the requirements of personalized production can be met, the pouring time is short, the speed is high, and the material utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a shape-variable mould. Background technique [0002] Additive manufacturing technology in the traditional sense is also commonly known as 3D printing, which can be summarized as "layered molding additive manufacturing technology". The core idea of ​​additive manufacturing can be summed up in one word, called Additive, which we can call discrete stacking. That is to discretize the three-dimensional model in the computer, and then manufacture the discretized parts (called sub-components) one by one, and the sub-components are accumulated to become the final component entity. Additive manufacturing technology in the traditional sense (referred to as additive manufacturing in a narrow sense) is simply: according to the three-dimensional design model of the workpiece formed on the computer, slice it layer by layer to obtain the two-dimensional profile information of the cross-section...

AI Technical Summary

Problems solved by technology

[0003] The main problem and disadvantage of the existing additive manufacturing technology is that it adopts the method of "model slicing and layer-by-layer accumulation", so the model printing time is long and the printing speed is slow, which cannot meet the needs of large-scale personalized production

Requires support structure, low material utilization rate, limited material selection range, and most technologies cannot print metal materials
