Description

Technical Field

[0001] This utility model relates to the field of die casting machine technology, and more specifically, to a direct injection mold for side injection and a die casting machine mold frame. Background Technology

[0002] Currently, die-casting machine mold frames on the market generally include a fixed plate, a tail plate, a movable plate, guide pillars, a mold opening and closing drive device, and a die-casting mold. The fixed mold of the die-casting mold can be mounted on the fixed plate, and the movable mold can be mounted on the tail plate. The mold opening and closing drive device can drive the movable plate to move closer to or away from the fixed plate, thereby enabling the fixed mold and movable mold of the die-casting mold to open and close. However, the feed inlet of existing die-casting molds is located on the end face of the fixed mold (i.e., the fixed mold base plate). The material needs to flow through the fixed mold base plate, fixed template, and fixed mold blank into the mold cavity formed between the fixed mold blank and the movable mold blank. This type of mold using end feeding has the following problems: the volume of sprue (i.e., scrap) is relatively large, which will cause material waste, increase production costs, and also greatly prolong the cooling time, reducing die-casting efficiency. Utility Model Content
