Multi-combined-station automatic core making center

Abstract

The invention discloses a multi-combined-station automatic core making center. The automatic core making center comprises a sand jetting rotary working device and a core model rotary working device, wherein the sand jetting rotary working device comprises a sand jetting rotary seat; a plurality of sand jetting worktables are arranged on the peripheral side above the sand jetting rotary seat; a sand jetting mechanism is arranged on each sand jetting worktable; a sand storage mechanism is supported on the top of the sand jetting supporting seat; the core model rotary working device comprises a core model rotary seat; a plurality of core model worktables with the amount which corresponds to the amount of the sand jetting worktables are arranged on the peripheral side of the core model rotary seat; a core jetting mold matched with the sand jetting mechanism is arranged on each core model worktable; and a sand blowing mechanism is supported on the upper side of the core model supporting seat. By utilizing the automatic core making center, the production of sand cores of a plurality of models can be performed at the same time, the sand receiving, sand jetting, fixing and core pulling processes can be performed at the same time, and meanwhile, the sand cores are effectively prevented from falling during the sand pulling process.

Description

technical field [0001] The invention relates to a casting machine, in particular to a core shooting machine. Background technique [0002] The core shooting machine used in the foundry industry now generally uses a single station for mold molding operations, which is carried out by one or two operators, and a series of processes such as sand shooting, shaping, and core pulling are completed at this station. The equipment leads to low production efficiency, high labor intensity and high equipment cost. In addition, most of the existing core shooting machines adopt the form of split-type mold opening, that is, two core-shooting half-opening molds are used to slide relatively. The outer sides of the two core-shooting half-opening molds are respectively connected with horizontal clamping cylinders. The horizontal clamping cylinder acts to control the closing of the two core-shooting half-open molds to carry out the sand-shooting process, and controls the separation of the two c...

AI Technical Summary

Problems solved by technology

However, during the core-pulling process, since the two core-shooting half-open molds slide outward respectively, the horizontal position of the shaped sand core cannot be fixed, and the randomness is very large, and it may be separated from the two core-shooting half-open molds. Open free fall, also possible with one of the two core-shooting half-open dies still connected

This kind of position cannot be fixed, which brings great difficulties to the core pulling work, and it is easy to cause the well-shaped sand core to fall, and the staff cannot catch it in time, resulting in damage to the sand core, which seriously affects the quality of the finished product

In addition, the existing core shooter can only produce sand cores of one model, and the amount of sand injected into the model at one time is limited. If another model of sand core is produced, it is necessary to replace the parts of the machine, such as the core shooter The box and the corresponding sand shooting mechanism, the replacement of parts brings inconvenience to the production and is easy to damage the parts
