Description
Technical Field

Background
With the development of society, machine manufacturers gradually replace manual trends with automation, and more automatic equipment is applied to numerous processing workshops. Automatic molding machines are also one of them and are favored by a wide range of foundry enterprises.
The casting or the mould is obtained by filling and compacting, wherein the filling, filling quantity, compacting and compacting quantity are important indexes related to whether the mould can meet the requirements, the filling is defined, a closed space is formed between a template, a sand box and a pressing plate by the relative movement of the pressing plate and the sand box, and the process of shooting sand into the space by a sand shooting cylinder is called filling. The filling amount is defined as the vertical distance between the upper and lower pressing plates and the upper and lower surfaces of the template when the equipment is in a filling state. Compaction is defined as the process of pressing loose sand in a sandbox by moving a pressing plate through an oil cylinder, so that the density of the sand blank in the sandbox is improved. The compaction amount is defined as the amount by which the platen is moved from the filled state to the compacted state and the height direction is changed.
However, the principle of the common molding machine is as shown in fig. 2, for products with large height-diameter ratio or products with large step difference, the molding density of the area A is greatly different from that of the molding density of the area B in fig. 2, for example, the height of a certain product is 150MM, the height of filled sand is 300MM, the compaction is 50MM,
a region compression ratio δ1==/>The A region density is improved>
B region compression ratio δ2==/>B region Density is increased->。
The friction between the mould wall and sand is considered to enable the density improvement of the lower part of the B area to be smaller, so that products with large height-diameter ratio cannot be molded in an automatic molding mode, or the density difference of sand blanks after molding is too large, so that the casting precision is uncontrollable, and products with large height-diameter ratio or large step difference cannot be finished in an automatic molding machine.
