Description

Technical Field

[0001] The utility model relates to the field of mold production and manufacturing, in particular to an auxiliary tool for drilling inclined holes in a mold. Background Art

[0002] The mold consists of a mold base and a mold core. The mold core is the core of the mold and its overall volume is much smaller than that of the mold base, generally only about one-eighth of the overall volume of the mold base. The mold core is the core component that comes into contact with the die-cast product and is generally processed using a machining center due to its high processing precision. Due to its large size, the mold base is generally processed using conventional drilling machines and other equipment. However, when it is necessary to drill an inclined hole in the mold core accommodating groove (for the mold core to be drawn out, etc.), conventional drilling machines and other processing equipment cannot drill the hole and can only be drilled manually. Although the precision requirements for this inclined hole are not high, the puncher needs to maintain a certain tilt angle at all times. At the same time, due to the high hardness of the mold steel, the drilling time is long and the drilling equipment needs to be pressed hard, so the labor intensity is very high. This can easily lead to a decrease in control force after the worker becomes tired, resulting in large hole errors in the drilling, which is very troublesome to repair. Utility Model Content

[0095] By rotating the gear 52, the depth slider 51 is driven to move along the embedded slot 511 and engage with the gear 52. After each rotation to a certain angle, the depth wrench 53 can be removed, and then the depth handle is reset and connected to the rotating gear 52, the action is similar to using an open-end wrench to tighten a nut.
