The ejector rod and the ejector pin plate are connected together. When the ejector plate is pulled out, the ejector plate is pulled back and the connecting rod and the ejector plate are connected Do all injection molding machines have this function?
In general case, the ejector and ejector plate of the injection molding machine are not connected together, and if they are connected together, the disassembly and assembly of the die will be very difficult. In fact, most die is reset by spring resetting mechanism. After the ejector plate is pushed out by the push rod, the push rod retracts and the spring rebound makes the thimble plate reset. The spring is installed on the guide post of the ejector plate. In a few cases, unable to install the spring to die, to connect the pusher and ejector plate, by putting back the thimble plate reset, then need a push rod extension rod (threaded at both ends, one end is rotation, reverse rotation, end) in the mold fixed before, first installed the long rod, the the push rod and the ejector plate are connected into a whole by the thread, the structure installed more trouble, so in most cases are the spring return. Some are not installed at the end of the reset mechanism, directly push out, by the closing of the die on the thimble plate reset, of course, this need to adjust the die pressure, otherwise, the mold will crash
This is called the thimble forced reset. The simplest is a good left hook, the top rod return distance, die a little trouble. On some machines, there is a hole in the top of the roof, with a wholeThread screws can be fixed on both sides. Toshiba injection machine is best installed. Some machines do not work, only with a retractor.
A kind of electric hydraulic machine is such, some do not push plate, but the structure principle and function setting and the push plate is the same, are used to set the nut fixed on the push rod and the push rod synchronous operation, the push plate device and iron pin for touch or induction top back two stroke switch jacking, some sensor switch, as long as the interest in this line, we should see more thought, more questions, more practice, don't be afraid of being talked about
Under normal circumstances, the injection molding machine push rod and ejector plate is not linked together, if linked together, disassembly and assembly mold will be very difficult.In fact, most die is reset by spring resetting mechanism. After the ejector plate is pushed out by the push rod, the push rod retracts and the spring rebound makes the thimble plate reset. The spring is installed on the guide post of the ejector plate.In a few cases, unable to install the spring to die, to connect the pusher and ejector plate, by putting back the thimble plate reset, then need a push rod extension rod (threaded at both ends, one end is rotation, reverse rotation, end) in the mold fixed before, first installed the long rod, the the push rod and the ejector plate are connected into a whole by the thread, the structure installed more trouble, so in most cases are the spring return.Some are not installed at the end of the reset mechanism, the direct push out, close to the die when the reset plate on the reset plate, of course, this need to adjust the mold pressure, carefully to the mold to crash Oh ~!
