Description

Technical Field

[0001] The utility model relates to the field of molds, and in particular to a molding mold for a water softener shell. Background Art

[0002] The mold is a tool used to make molded products. Different shapes of molds are used to make products of different shapes, such as Figure 1-2 The water softener shell shown in the figure has a shell size (length × width × height): 512mm × 390mm × 614mm, and the overall size is large. A vertical through cavity is opened on the front of the water softener shell, and two mounting holes are opened on the outer front of the water softener near the upper edge. Due to the large overall size of the water softener, high-pressure glue injection into the cavity is used to improve the molding efficiency. The high-pressure glue injection process will cause the molding rod originally placed in the cavity for forming the mounting hole to be pushed out of the cavity, resulting in the inability to form the mounting hole of the water softener.
