Abstract
A low pressure injection mold includes a failsafe pressure mechanism that prevents the low pressure injection mold from being subjected to excessive injection pressures or excessive clamping tonnage that could damage the low pressure injection mold.
Claims7
An injection molding apparatus comprising:
- a melt holder for pressurizing a molten material prior to injection;
- an injection system for injecting the molten material from the melt holder into a mold;
- a sensor for sensing a melt pressure of the molten material within the apparatus;
- a controller that is:
- communicatively connected to the sensor, to receive a pressure signal from the sensor, and
- communicatively connected with the injection system;
- and
- means for preventing installation of a mold into the injection molding apparatus when the injection molding apparatus is capable of injecting molten material at pressures in excess of a maximum design pressure for the mold.
