Embodiment Construction

[0037] Hereinafter, the casting molding machine of this embodiment is demonstrated based on drawing. figure 1 It is a longitudinal sectional view showing the state (initial position) before the start of the casting molding machine 100 according to the embodiment. figure 2 It is a longitudinal sectional view of the casting molding machine 100 showing a state in which a molding space is formed. The mold molding machine 100 is a molding machine for molding a mold using a loaded mold box and a template.

[0038] Such as figure 1 , figure 2 As shown, the casting molding machine 100 includes, for example, a base frame 1 . A fixed stopper 2 is fixed to the base frame 1 . On the left and right sides of the molding base 3 formed by the base frame 1 and the fixed stopper 2 (refer to figure 1 ), upwards are provided with sand boxes to set cylinders 4,4. One of cylinder 4,4 is set in sand box (in figure 1The center part of the model changing device 5 is supported so as to be ...

Abstract

A mold molding machine, which uses a molded box and a template to mold a mold, which includes: a storage box, which has a lower opening that can be connected to the upper opening of the mold box; a pressure head mechanism, which can Relative to the pressing plate that enters and exits in the storage box, and multiple presser feet that pass through the pressing plate and can be raised and lowered relative to the pressing plate; the sand filling hopper has the ability to fill the molding space formed by the molding box, storage box, pressure head mechanism and template At least one sand filling port for molding sand; and a sand filling nozzle, which is arranged on the side of the storage box and can communicate the sand filling port with the molding space.

Description

technical field [0001] The disclosure relates to a mold molding machine, a sand filling compression unit, and a mold molding method for molding a mold by extruding sand filled in a mold box. Background technique [0002] Conventionally, there is known a mold molding machine that fills a molding box with molding sand by air inflation and squeezes the filled molding sand to mold a mold (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2002-1491 [0004] However, in the device of Patent Document 1, the sand filling nozzle is formed on the platen (cover member) (refer to Patent Document 1 Figure 5 ). Therefore, there is a problem that the arrangement of the presser foot on the presser plate is limited. When the arrangement of the presser foot on the presser plate is limited, there is a concern that the effect of the presser foot cannot be sufficiently exhibited depending on the shape of the template. In this technical field,...
