Hydraulic pusher system is mainly used for foundry mold handling. This system is operated with hydraulic PLC control, actuators & sensors.in this, process timing is set to push pallet cars by using sensors to check the time to push the mold of the molding machine.
Mould handling is an important factor for determining the productivity of foundry where sequence of operations carried out in a quick session of time. Therefore, effective handling of mould is highly essential to balance the operation requirements in a short span of time. The present invention is about implementing the effective material handling in foundry operations through powerised pusher trolley with inbuilt hydraulic power pack. the proposed trolley could move along transfer tracks through mechanical power acquired from an electric motor The heavily made wheel blocks mounted on the corners of the trolley increases the durability of the trolley The inbuilt hydraulic power unit transfers the mould box from transfer track to working tracks as per the sequence of operation. This invention eliminates the use of individual hydraulic cylinders for each working track.
Powerised transfer trolley system is an important part in mold handling.it is used to carry the molded mold or knockout mold box from one track to another. Heavy fabrication structure, heavy wheels, plumber block bearing, shaft & gearbox break motor are used in this trolley. The trolley is started & stopped at accurate position with the help of VFD control, sensors & break motor.
Punch out machine is an important component of auto mold handling. This machine is hydromechanics and plc operated. they takes the knockout from the pouring mold track lines and puts the mold sand in the mold box along with the casting punch and puts the knockout on top and keeps the mold box on the return position.
The moulding box play a vital role in the foundry industry, a molding box divided into two halves (known as casting flask, the top and bottom halves of which are known respectively as the cope and drag) is prepared to receive the pattern. Which itself is divided along this parting line. Molding boxes are made in segments that may be latched to each other and to end closures. Ribs are provided on molding box. These ribs are specially provided for larger boxes for avoiding the mould breaking by sand load. Both the Top and the Bottom of the mould boxes are machined completely to get the parallel by this positive closing can be achieved.
We are involved in manufacturing & supplying industrial foundry pallet cars. These pallet cars are widely used for foundry ARPA & high pressure lines. mould cars are used for mold handling in foundries. Because of continuous working of pallet cars in mold handling system, we make it high rigidity, for that we use supported ribs. Special U shape rollers we manufacture in heavy duty alloy steel are used for self guiding. We design a special grove on top side of the pallet car to escape gases from the pouring mould. We design thickness & size of the pallet according to the weight & size of the mould box. Since we machined this pallet car on totally VMC machines, its paralleled and total pallet cars distance was maintained with a difference of about +/-0.2mm so it helps to operate the puller pusher system assembly smoothly.
We make the cast iron mould Weights & aluminum mold jacket for High-pressure moulding line.
