One-box multi-cast plate and casting method

Abstract

The invention discloses a one-box multi-cast plate and a casting method, belongs to the technical field of casting molds and casting methods, and is used for a one-box multi-cast process. According to the technical scheme, the one-box multi-cast plate comprises an upper template and a lower template, wherein a plurality of upper part models and an upper pouring opening model are processed on the upper template; a plurality of lower part models and a lower pouring opening model are processed on the lower template; the upper part models and the lower part models are matched with each other; the upper pouring opening model and the lower pouring opening model are matched with each other; and sand box positioning devices are respectively arranged on two sides of the upper template and the lower template. The casting method comprises the steps of: preparing the designed templates for shaping; after shaping is finished, correcting a cavity; smearing fireproof materials in the cavity; and pouring. The process is simple; the shaping efficiency is greatly improved, and the utilization rate of casting sand is greatly improved; a standard sand box is beneficial to automatic casting; due to the high-precision templates, the blank precision of a casting is improved; and the one-box multi-cast plate can meet various requirements of castings with different shapes.

Description

technical field [0001] The invention relates to a casting pattern plate for black metal resin sand sand casting and a casting method using the pattern plate, belonging to the technical field of casting models and casting methods. Background technique [0002] The foundry field is an important link in the machinery manufacturing industry, which directly determines the quality of the product blank and the economy of machining, which is directly related to the cost and efficiency of the production product. The rapid development of the casting field has made the production of complex and thin-walled workpieces easy. With the development of enterprises and the increase of market demand, manual production methods alone are not enough to meet market demand. Therefore, automated production is the development of enterprises. Inevitable direction. [0003] For the existing casting technology, the casting of small-sized parts is mainly carried out by the method of one piece and one bo...

Problems solved by technology

Part models and gating system models have no fixed positions in the sand box, and their positions in the sand box are determined by the operator, resulting in the casting blank and casting yield are not fixed

Moreover, in the existing casting technology, it is a trend to increase the filling capacity of the casting by reducing the gating system, but it also causes some other problems: First, because the gating system is small, the size of the sand box used is also small. When the demand is large, the number of repeated moldings and the number of small sand boxes are large, which not only reduces the efficiency of the molding stage, but also makes it difficult to place the sand boxes in the foundry workshop and make boxes in the subsequent order; secondly, there are many sand box specifications, not only Reduce the utilization rate of the sand box and reduce the utilization rate of the molding sand

[0004] In order to overcome the disadvantage of one box with one piece, the existing casting technology also adopts the method of one box with multiple castings, but at present, in the process of implementing the molding process of one box with multiple castings, the layout of the part model and the gating system model needs to be manually operated, resulting in The gating system of the same part is not uniform, and the casting effect of the parts is different, which also leads to different sizes of casting sand boxes, which set obstacles for the automation development of casting
