Horizontal parting snap flask molding machine being labor-saving in die picking and placing and easy in casting

Abstract

The invention provides a horizontal parting snap flask molding machine being labor-saving in die picking and placing and easy in casting, which is good in reliability and can produce sand moulds in high efficiency. The molding machine comprises an engine base, wherein a lower supporting plate is connected with a lower lifting drive device; a lower sand mould bottom plate is connected with an intermediate lifting drive device on the lower supporting plate; a lower sand mould frame is arranged on the lower supporting plate through a lower elastic element; an upper supporting plate is connected with an upper lifting drive device; an upper sand mould frame is arranged on the upper supporting plate in an up-down lifting manner; an upper elastic body is arranged between the upper sand mould frame and the upper supporting plate; two outlets of a sand blasting hose are communicated with the upper sand mould frame and the lower sand mould frame; a die splitting plate is arranged between the upper sand mould frame and the lower sand mould frame; a runner die core passes through the upper sand mould bottom plate; a conical die passing through the runner die core is formed in the lower surface of the upper sand mould bottom plate; a pore is formed in each supporting plate; the periphery of the die splitting plate is supported on the upper surface of each supporting plate around the pores; the supporting plates are connected with left and right movable drive devices.

Description

technical field [0001] The technology relates to a molding machine for sand molds for casting, specifically, a horizontal split type out-of-box molding machine. Background technique [0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. However, the sand molds used in casting are generally made by hand, which is labor-intensive and low in production efficiency. Contents of the invention [0003] The purpose of this technology is to provide a horizontal parting and out-of-box molding machine with good reliability, which can produce sand molds with high efficiency, labor-saving pick-a...
