MOLD ASSEMBLY

摘要

This disclosure relates to a molding machine for molding hollow articles, such as bottles, which are provided with an opening therein. The molds of the machine are modified so that each has incorporated therein a cutter which is operable after a member has been blown therein to cut off the parison material at one end and to form the desired opening in the member. The cutter is automatically actuated by means of a cam as the mold passes a predetermined position in its path of travel. Further, the cam is resiliently mounted so as to absorb shock and to prevent jamming of the mold structure in the event of blockage of the actuation of the cutter. The resiliently mounted cam has associated therewith switch means for shutting down the machine upon predetermined excessive movement of the cam.
