Auxiliary core-adhesive apparatus of combined mud core

Abstract

The invention provides an auxiliary core-adhesive apparatus of a combined mud core. The combined mud core includes a large mud core and a small mud core. The auxiliary core-adhesive apparatus includes a pedestal on which a supporting column is arranged. A top plate is disposed on an upper end of the supporting column. An internally-concaved position-limiting groove is disposed on a front end of the top plate. A left-right-direction rotating shaft is arranged on the top plate. A position-limiting frame, which can turn around the rotating shaft, is arranged on the rotating shaft. The small mud core is tightly clamped between the position-limiting frame and the position-limiting groove which are matched with each other. A plurality of connecting members are arranged on the pedestal and are matched with and connected to the large mud core. The auxiliary core-adhesive apparatus is applied in a combining and bonding process between the large mud core and the small mud core in the combined mud core. By means of cooperation between the position-limiting frame and the position-limiting groove, the small mud core is firmly pressed inside the position-limiting groove by means of gravity of the position-limiting frame itself so that a position and size requirement of the small mud core can be accurately ensured. By means of the auxiliary core-adhesive apparatus for carrying out an auxiliary core-adhesive operation, not only is working time of operators fully utilized but also work efficiency can be greatly increased.

Description

technical field [0001] The invention relates to the field of casting molds, in particular to an auxiliary core sticking device for a combined core. Background technique [0002] With the rapid development of China's industry, the structure of various products is becoming more and more complex. In the field of casting, due to the increase in the complexity of product structure, casting molds have changed from a single core to a combined core that requires several cores to be combined; at the same time, due to the needs of production and life, people's requirements for products It is also becoming more and more stringent, which is mainly reflected in the improvement of the internal quality requirements of the product and the improvement of the dimensional accuracy requirements of the product. The composite core in the casting mold includes a large core and a plurality of small cores. The small cores are glued to the large cores by glue, and the glue generally takes about 30 s...

AI Technical Summary

Problems solved by technology

The combined core in the casting mold includes a large core and a plurality of small cores, the small cores are glued to the large cores by glue, and the glue generally takes about 30 seconds to solidify. Hold the small core and keep the small core in place until the glue solidifies. The small core adheres to the large core, and then the staff releases the small core to do other work. The dimensional accuracy between Ni core and Da Ni core, this process can no longer meet the current production requirements; therefore, how to adjust the stick core process to improve product quality is an urgent problem to be solved
