Tiebar Nuts and Gears for Injection Molding Machine Or Die Casting Machine

Tiebar Nuts And Gears for injection molding machine or die casting machine

 

Nuts and gears adjustable Tie Bars of an injection molding machine or die casting machine during operation, includes a threaded sleeve securing one end of each of the threadless tie bars to a backing plate with an adjustable nut positioned between the backing plate and threaded sleeve for adjusting the machine lockup tension on the Tie Bar.

 

The adjustable nut associated with each of the four tie bars has gear teeth and can be adjusted by means of disengagable idler gears commonly engaging a centrally located bull gear for selectively adjusting one or more of the tie bars.

 

In one embodiment of the invention, strain gauges are placed on the threaded sleeves for detecting the lockup force applied to the tie bars through the sleeves and an electrical control circuit is employed for automatically controlling the tie bar adjustment mechanism to maintain tie bar tension within prescribed limits during production operation of the injection molding machine or die casting machine.

 

We select material (such as 45#, 40Cr, 42CrMo and others) based on customer requirements and provide blacking, chrome plating, salt bath nitriding, gas nitriding and other heat treatment processes.
