Problems solved by technology

[0005] This known way of facilitating the rotation of the wobble plate is quite complex, as it involves the cooperation of two lever arms (rod and cam) with joints, which are connected to each other and to the wobble Boards and Racks
This known type of rotary mechanism, which comprises a number of movable parts and joints, requires constant maintenance and periodic repairs of said elements, which can lead to production stops, therefore in addition to the disadvantages already mentioned In addition, it also resulted in a huge loss of production

Abstract

The invention pertains to a vertical sand moulding machine 2, comprising a moulding chamber 4 formed by a bottom wall 6 and an upper wall 8 provided with one or more sand filling openings 10, communicating with a sand feed system 12. The moulding chamber 4 is also delimited by two side walls, a pressure plate 14 provided with a pressure pattern 16 and connected to a movement mechanism 18, and a swingable plate 20 provided with a swing pattern 22 and mounted for translational and swivelling movement in order to open and close the moulding chamber 4, allowing the pressure plate 14 to expel the produced moulds. The sand moulding machine 2 further comprises a first device 26, which is fixed to the swingable plate 20 and is adapted to cooperate with a second device 28, which is connected to another part of the sand moulding machine 2, for swivelling the swingable plate 20.

Description

technical field [0001] The invention relates to a sand molding machine, especially a vertical sand molding machine provided with a rotating mechanism. Background technique [0002] Sand molding machines of the above type have been known in the art for many years. Examples of known vertical sand molding machines are described in US 3,008,199 and US 4,442,882. These sand molding machines comprise a mold cavity formed by a bottom wall, an upper wall provided with one or more sand filling ports communicating with a sand supply system, and two side walls. The mold cavity is also delimited by a press plate and a swing plate, the press plate is provided with the die and is connected to the kinematic mechanism. The oscillating plate is provided with oscillating dies and is mounted for translational and rotational movement in order to open and close the mold cavity, thereby allowing the press plate to eject the finished moldings. [0003] The general operating principle of this ty...
