Pin-type mold base
The pin-type mold base connects the upper and lower mold bases through guide blocks and pins. Combined with the mold positioning groove and bolts to fix and clamp the mold, it solves the problems of unstable mold base fixation and poor adaptability, and realizes high-precision drill rod upsetting and low-cost processing.

Abstract
This utility model relates to the field of mold technology and discloses a pin-type mold base, including an upper mold base, a lower mold base, and a guide block. Both sides of the upper and lower mold bases have mounting slots extending along their length. At the ends of the lower and upper mold bases that are far apart from each other, mold base fixing slots are formed on both sides, communicating with the corresponding mounting slots. At the ends of the lower and upper mold bases that are close to each other, semi-circular slots are formed. Multiple mold positioning slots are formed within these semi-circular slots along their length. At the ends of the lower and upper mold bases that are close to each other and located on both sides of the semi-circular slots, multiple guide slots are formed. The guide block is fixed in the guide slot of the lower mold base by a fixing member, with its upper end inserted into the guide slot of the upper mold base. This utility model, by setting guide blocks and pin fixing, achieves a stable connection between the lower and upper mold bases, improves the overall structural stability of the mold base, and ensures accuracy during the drill rod upsetting process.
