This invention relates to flaskless molding equipment for molding a mold that provides support for quickly restoring the stopped equipment to a normal operation. The control circuit (sequencer 200) monitors the movements of the movable members (lower squeezing board 4, lower filling frame 6, upper flask 10, master plate 22, and pusing plate 32), the cylinders (cylinder for squeezing a set of flasks 2, cylinder for a lower filling frame 5, cylinder for upper flask 9, pattern-shuttle cylinder 21, and cylinder for pushing molds 31), and the mechanisms for driving a cylinder (mechanism driving a cylinder for squeezing a set of flasks 400, etc.), and if the period of the operation of each step of the flaskless molding equipment for molding a mold from the start of the operation to the point where the operation of the flaskless molding equipment for molding a mold reaches the predetermined position exceeds the predetermined period that is set to be abnormal, then the control circuit provides support for restoring the stopped equipment to a normal operation, following the instructions displayed on the screen and following the operator's input by means of an input switch.

A method of operation for an apparatus for making an upper and a lower mold and the apparatus therefore that can prevent a mold from having a-wrap or a match plate from being damaged.

The apparatus for making an upper and a lower mold of the present invention controls the forward movement of an upper and a lower squeeze member such that when they each move forward to the match plate by means of the squeeze means of the upper and lower molds the difference in the squeeze forces imparted by the upper squeeze means to the upper squeeze member, and the squeeze force imparted by the lower squeeze means to the lower squeeze member, is kept within the predetermined tolerance.

Core making apparatus having a frame (12) and capable of producing cores at a moulding position within the frame (12) can be configured to include one or more horizontal core box handling components (62,64) and/or one or more vertical core box handling components (174,176). The machine may be adapted to many different foundry needs.

The invention provides a forming machine without pattern casting, comprising: a multi-axis motion system which at least comprises an X-axis motion system, a Y-axis motion system and a Z-axis motion system, and a workbench which is below the multi-axis motion system; and further comprises: a moving platform system below the workbench, comprising a moving bracket which can reciprocate along the direction parallel to the X axis, a lifting device provided on the moving bracket, which is used for lifting and supporting the workbench to enable the linkage between the workbench and the moving bracket. The forming machine without pattern casting of the invention can move the workbench without a lifting tool, and machine a casting mold with a large size and a complex cavity, and causes little pollution to the environment.

A hydraulic power unit 15 of a match-plate molding machine comprises a hydraulic pump 20 for supplying oil, a piping system 21, 25, and 26 that fluidly communicates with first and second hydraulic cylinder systems 7 and 10 for supplying the oil from the hydraulic pump 20 to them to perform a squeeze step, an accumulator 22 that is provided within the piping system, first and second electromagnetic directional control valves 23 and 24 for controlling the flow of the oil from the hydraulic pump 20 to the first and second hydraulic cylinder systems 7 and 10, first and second pressure sensors 27 and 28 for measuring pressures of the oil of the first and second hydraulic cylinder systems 7 and 10, and for generating output signals that correspond to the measured value, and a controller 29 for receiving the output signals from the first and second pressure sensors 23 and 24, and for controlling the turns of the first and second electromagnetic directional control valves 23 and 24 based on the output signals and the predetermined value within a range below the pressure holding the accumulator 22 against the oil.
