Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present utility model;
Fig. 2 is the A-A direction cross-sectional schematic in Fig. 1 of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further explained:
Specific embodiment
As shown in Figure 1, the utility model provides a kind of wear-resisting injection plunger of lowering the temperature, this injection plunger comprises injection plunger body 1 and is located at the injection plunger push rod connector 2 of injection plunger body 1 one end, one end of injection plunger push rod connector 2 connects injection plunger body 1, the other end connects injection plunger push rod, injection plunger body 1 comprises housing 10 and is arranged on the inner bag 11 of housing 10 inside, the thickness of housing 10 is 8-10mm, the thickness of the present embodiment middle shell is 8mm again, so that enclosure interior has enough large space, inner bag 11 can be assembled in housing, the circulating water of die casting machine self-cooling system is used to reach the effect of cooling.
