一、前言1.适应中小型铸造车间生产的需要,作为系列产品之一:我国中小型铸造车间机械化造型,主要使用的是震击式和震压式造型机,如 Z145A 震压式造型机已在国内广泛使用。由于震击与震压式造型机噪音大,生产率低等问题,近几年来国内正逐步使用气动微震压实造型机。气动微震压实造型机的主要特点是压实的同时进行震击,因此可得到紧实度分布良好的砂型。另外气动微震压实造型机生产率高,振动较小,对基础要求低,噪音小等特点。从目前来看,国内外已用气动微震压实造型机逐步代替震击式和震压式造型机。
I. Introduction 1. To meet the needs of small and medium-sized foundry production, as one of a series of products: China’s small and medium-sized foundry mechanized shape, the main use of shock and shock compression molding machines, such as Z145A shock compression molding machine has Widely used in the country. Due to the shock and shock pressure molding machine noise, low productivity and other issues in recent years, China is gradually using pneumatic microseismic compaction molding machine. Pneumatic microseismic compacting molding machine is characterized by the compaction of the shock at the same time, so you can get a good distribution of sand compactness. In addition the pneumatic microseismic compacting machine high productivity, less vibration, low on the basis of the request, the noise is small and so on. From the current point of view, domestic and foreign pneumatic microseismic compacting machine has gradually replaced the shock and shock compression molding machine.
