Sand mould composite molding equipment

Abstract

The invention provides sand mould composite molding equipment which comprises a planar motion system, an exhausting dust collection system, a motion control system and the like, and is characterized by further comprising a molding sand feeding system, a resin injection system, a cutting system, a multifunctional platform system and the like. When a casting mold is thick, heavy and large in size and suitable for cutting molding, a multi-shaft planar motion system is adopted to drive the cutting system to complete the cutting molding of the casting mold; when the casting mold is provided with a complicated internal cavity structure and suitable for dispersed / accumulated molding, the multi-shaft planar motion system is adopted to drive the resin injection system to perform dispersed / accumulated molding on the casting mold under the assistance of the multifunctional platform system and the molding sand feeding system; the sand mould composite molding with the bottom to be cut and the top to be accumulated can also be performed. With adoption of the sand mould composite molding equipment, the cutting molding, the dispersed / accumulated molding and the sand mould composite molding of a large or medium casting mold with any shape can be realized, so that the equipment investment is greatly reduced; in addition, a proper molding manner can be selected, the manufacturing speed and quality of the casting mold can be improved, and the sand mould composite molding equipment has the value of popularization and application.

Description

technical field [0001] The present invention relates to the field of casting technology, more specifically, to a rapid manufacturing equipment for casting moulds. Background technique [0002] In order to improve the quality of single-piece and small-batch molds, reduce production costs, and reduce production cycles, the casting mold manufacturing technology based on the principle of discrete accumulation forming and direct numerical control cutting forming has emerged as the times require. The two technologies provide a convenient way for the trial production of new products, but both technologies have their own advantages and disadvantages. Discrete accumulation forming can be formed in any shape, but it is time-consuming to lay materials layer by layer, especially when thick and heavy molds are involved. Its disadvantages are long processing time and poor forming quality; casting mold CNC cutting forming has the advantages of fast and high-precision forming, but the casti...

Problems solved by technology

[0003] The current rapid prototyping manufacturing equipment is based on a certain forming principle, but due to the advantages and disadvantages of various forming principles, in the face of complex and changeable casting molds, different forming principles are often required to complete the manufacturing, and even more This process involves multiple pieces of equipment, which requires the manufacturer to invest a lot of money. At present, all equipment only provides one forming method, and the processing method is greatly restricted.
