Embodiment Construction

[0025] Figure 1 to Figure 4 One embodiment of the tankless molding device of the present invention is described. This boxless molding device generally includes a main body unit 1 positioned on a mechanical frame 20 of the device, and a double-sided template 11 ( figure 2 ) into and out of the transmission device 2 ( image 3 ), and a mold ejection device 3 for ejecting the final upper and lower molds molded in the main body unit 1 from the upper and lower flasks 12 and 13. Both sides of the double-sided template 11 are provided with patterns.

[0026] 1. The main unit of the molding device

[0027] On the styling device of the present invention, its main unit 1 will be described first. optimally, as figure 2 As shown, the main body unit 1 includes an upper sand box (a first sand box) 12 and a lower sand box (a second sand box) 13, the double-sided template 11 can be clamped therebetween, one can be inserted into the upper sand box and An upper extruding member 14 oppo...

Abstract

The disclosed molding machine defines upper and lower mold cavities while cope and drag flasks 12,13, having a match plate 11 sandwiched therebetween, are rotated from their horizontal positions to their vertical positions. An upper squeeze member 14 is insertable into the cope flask 12 with its pressure-applying plane being opposed to the upper face of the match plate 11. The pressure-applying plane defines an upper mold cavity together with the upper face of the match plate 11 and the cope flask 12. A pivoting frame 23 supports the cope and drag flasks 12,13, having a match plate 11 sandwiched therebetween, and the upper squeeze member 14, such that they rotate in unison between a horizontal position, in which the pressure-applying plane of the upper squeeze member 14 is oriented vertically downward to a vertical position in which the pressure-applying plane is oriented horizontally. A fixed, vertical, filling frame abuts the drag flask 13 when the cope and drag flasks 12,13, having the match plate 11 sandwiched therebetween, are in the vertical position. A lower squeeze member 16 has a pressure-applying plane that is oriented horizontally, and is insertable into the filling frame and the abutted drag flask 13. The pressure-applying plane of the lower squeeze member 16 defines a lower mold cavity together with the lower face of the match plate 11, the drag flask 13, and the filling frame 15.

Description

technical field [0001] The invention relates to a molding device, in particular to a device for simultaneously molding upper and lower boxless molds. Background technique [0002] In the tankless molding method, an attempt was made to improve work efficiency by employing a well-known tankless molding device. For example, earlier Japanese Patent Publication No. 04-66245 proposes to combine a well-known tankless molding device with a pattern changing device. The pattern is changed mechanically and automatically, rather than manually, by replacing a used pattern template used to form the mold in the molding device with a new pattern template. [0003] However, the tankless molding devices of the above publications are well known and have also been used in conventional tankless molding methods in which the changing of pattern templates is manual. Therefore, this disclosure is consistent with the traditional boxless molding method of manually changing pattern templates in the p...
