Abstract

The utility model discloses an efficient sand core head positioning tool which comprises an upper casting mold and a lower casting mold, sand cores are arranged in cavities of the upper casting mold and the lower casting mold, core heads are arranged on the two sides of each sand core, positioning pins are inserted into the core heads in a penetrating mode, and positioning holes are formed in the positions, corresponding to the core heads, of the upper casting mold and the lower casting mold. A plurality of groups of positioning holes are formed in the base, round grooves are formed in the sides, away from each other, of each group of positioning holes, round blocks are arranged in the round grooves, pressing blocks are arranged on the corresponding sides of the round blocks, studs are arranged on the inner walls of the sides, away from each other, of the round grooves, and threaded sleeves fixedly connected with the round blocks are arranged on the outer portions of the studs in a sleeving mode through threaded structures. The efficient positioning tool for the core head of the sand core can play an auxiliary reinforcing role on the core head, the accuracy and firmness of the sand core during positioning are improved, and the reliability is higher.
