Technical Field
The utility model relates to a molding machine field, concretely relates to a hydraulic assembly for molding machine.
Background
When the molding machine for casting the soil-stained sand is used, firstly, air pressure is utilized to blow the molding sand into a sand box provided with a mold, then, the molding sand is extruded and molded by utilizing the force of hydraulic pressure, air pressure or a motor and the like, then, the mold is taken out, then, the sand mold bodies taken out of the mold are combined together to form a complete molding sand body, and then, the molding sand body is moved to a casting platform or a position for casting.
When the existing molding machine is used for manufacturing a sand mold, the upper sand box and the lower sand box are required to be moved to the designated positions to be aligned with a sand shooting opening, then sand shooting operation is carried out, and after sand shooting, the lower pressure plate is driven to move to compact sand grains. Because the upper pressing plate and the lower pressing plate do not apply pressure simultaneously for extrusion, a mould in the sand mould is easy to deform under pressure, and the manufactured sand mould is easy to damage due to uneven upper and lower pressure. Meanwhile, the existing molding machine is generally driven by a plurality of air cylinders or oil cylinders. However, the cost of using multiple cylinders or cylinders is greatly increased, and the failure rate is also increased. A plurality of cylinders are difficult to guarantee that the upper pressing plate and the lower pressing plate are synchronously and accurately extruded.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention is directed to a hydraulic assembly for a molding machine, which has a simple structure and can perform a synchronous high-precision extrusion operation.
In order to realize the technical purpose, the utility model discloses a scheme is: a hydraulic assembly for a molding machine comprises a rack, a motor, a pump body, an oil storage tank and a cooling module, wherein the oil storage tank is arranged at the lower part of the rack and is communicated with the pump body through a pipeline;
and a cooling module is also arranged on one side of the rack.
Preferably, the pump body is also communicated to a lifting oil cylinder for lifting and lowering the drag flask through the switching module.
Preferably, a temperature sensor is further provided in the oil storage tank.
Preferably, the upper pressing plate and the lower pressing plate are further provided with pressure sensors, and the pressure sensors, the motor and the cooling module are further electrically connected with the control module respectively.
The beneficial effects of the utility model are that through the hydraulic component of the application, the upper press plate and the lower press plate of the molding machine can be conveniently pressed up and down simultaneously, the molding machine can be synchronously extruded and mutually advanced and retreated, high-precision sand molds are manufactured, and the sand molds can not be extruded and damaged due to unidirectional stress when in use; the die mechanism is simple in structure, accurate in control and high in efficiency, and effectively solves the problems that a single die in an old mechanism is extruded downwards and upwards to damage the structure of the die mechanism, the structure is complex, the failure rate is high and the like.
Drawings
FIG. 1 is a schematic diagram of a hydraulic assembly for a molding machine according to the present invention;
fig. 2 is a schematic view of a partial structure of the present invention used in a molding machine.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, a specific embodiment of the present invention is a hydraulic assembly for a molding machine, including a frame 1, a motor 2, a pump body 3, an oil storage tank 4, and a cooling module 5, wherein the oil storage tank 4 is disposed at a lower portion of the frame 1, the oil storage tank 4 is communicated with the pump body 3 through a pipeline, the motor 2 is in driving connection with the pump body 3, the other end of the pump body 3 is respectively communicated with an upper oil cylinder 7 and a lower oil cylinder 8 through a switching module 6, the upper oil cylinder 7 is used for a lower pressing plate 9 of the molding machine to move downward for performing a compacting operation, and the lower oil cylinder 8 is used for an upper pressing plate 10 of the molding machine to move upward for performing a compacting operation;
and a cooling module 5 is also arranged on one side of the frame 1. During the use, through the control of switching module, can realize the synchronous linkage of top board and holding down plate, the extrusion preparation molding sand simultaneously.
For better control of the molding machine, the pump body 3 is also connected via an adapter module to a lift cylinder 11 for the drag flask lifting movement. After the lower sand box is controlled to ascend and descend to a specified position through the lifting oil cylinder, stopping, and then controlling the upper pressing plate and the lower pressing plate to synchronously extrude to compact the sand mold.
For better protection of the hydraulic components, a temperature sensor is also arranged in the oil storage tank 4. If the temperature is too high, the flow speed of the condensate in the cooling module can be increased, and the cooling is accelerated.
For the pressure in the accurate control extrusion process, still be provided with pressure sensor on upper pressure plate 9 and the lower pressure plate 10, pressure sensor, motor and cooling module 5 still are connected with control module electricity respectively. The pressure sensor can accurately know the pressure change condition of the upper pressure plate and the lower pressure plate in the extrusion forming process. Meanwhile, the control module can be used for stopping when the pressure change exceeds a threshold value, so that the card machine fault caused by the low parallelism of the pressing plate in the use process can be effectively reduced.
