Molding machine device capable of avoiding infirm casting caused by gaps among gravels

Abstract

The invention relates to the technical field of precoated sand molding, and discloses a molding machine device capable of avoiding infirm casting caused by gaps among gravels. The molding machine device comprises a shell, wherein a movable plate I is movably connected to the bottom in the shell, and a drive shaft is movably connected to the interior of the left side of the movable plate I; and a first wedge-shaped block is fixedly connected to the right side of the drive shaft, and a first vertical rod is movably connected to the interior of the first wedge-shaped block. According to the molding machine device capable of avoiding infirm casting caused by gaps among gravels disclosed by the invention, a drive motor on the left side of the drive shaft is started, and a secondary shaking table drives a mold cylinder to shake at the moment, so that the effect of preventing the casting quality from being influenced by more gaps among the gravels in the casting process is achieved. When a crank is rotated, a slide block moves forwards and backwards on the outer wall of a threaded rod at the moment, so that the angle of the cam is changed, the shaking frequency of the mold cylinder is further changed, and the effect of changing the shaking frequency according to different types of gravels is achieved.

Description

technical field [0001] The invention relates to the technical field of coated sand molding, in particular to a molding machine device that prevents unreliable casting caused by gaps between sand and stones. Background technique [0002] Coated sand is a kind of molding sand or core sand whose surface is covered with a layer of solid resin film before molding. When molding coated sand, it is necessary to use a molding machine. The main function of the molding machine is: filling sand, loosening The molding sand is filled into the sand box; the sand is compacted, and the loose sand in the sand box is compacted by different methods such as vibration, compaction, shock pressure, and injection pressure, so that the molding sand has the necessary strength in the process of handling and casting. . [0003] However, the sand filling ability of the existing molding machine is insufficient, and it is impossible to compact the sand and gravel particularly firmly, so that there are gap...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a molding machine device that avoids the gaps between the sand and stones resulting in unreliable casting, and has the advantage of preventing more gaps between the sand and stones from affecting the quality of the casting during the casting process. Solved, but the sand filling ability of the existing molding machine is insufficient, and it is impossible to compact the sand and gravel particularly firmly, so that there are gaps between the sand and gravel. During the casting process, more gaps will make the casting unreliable , which is not conducive to the problem of later handling and removal
