PURPOSE: To easily judge the finish of purging for oneself by a structure wherein a resin receiving device, which receives resin purgings under the condition that the injection part of an injection molding equipment is arranged below a die plate and then slid horizontally so as to abut the injection part against the resin receiving device, is provided on the frontal operating side of the injection molding equipment.

CONSTITUTION: In order to purge resin, an actuator 70 is put into actuation so as to lower a rocking stand 90 until the stand 90 abuts against a block 72. Then, a stand 60 is slided horizontally so as to move by the predetermined amount in order to reach the position of a resin receiving device 100 of resin purgings. By feeding pressure oil to the actuator 70, the rocking stant 90 is raised so as to abut the tip of an extension 34 against the resin receiving device 100 of resin purgings. By feeding pressure oil to an injection driving device 36, an injection part is put into actuation so as to carry out purging. Purged resin flows down from the resin receiving device 100 of purgings or gathers them in a resin reservoir. By seeing the flown or gathered resin from the frontal operating side of the injection molder, the finish of purging of resin can be judged, resulting in allowing to easily carry out purging for oneself.
