Problems solved by technology

[0002] At present, the lower sand box on the molding machine on the market does not use a vibrator, and it is common that the molding sand cannot fill the cavity well, resulting in the sand mold being easily loosened during the transportation process, and the sand mold and the sand box are separated during the mold removal process of the upper and lower boxes. Difficult to mold, easy to shape and stick to the box

Embodiment Construction

[0014] The following further description with reference to the drawings does not limit the scope of the present invention.

[0015] See Figure 1 to Figure 3 As shown, the present invention includes a lower flask, a mounting beam 1 and a shell 5. The mounting beam 1 is fixed on the lower flask, the shell and the mounting beam 1 are fastened together by bolts, and the shell 5 is provided with a cavity, a vibrating ring 6 is installed in the cavity, a cover plate 7 is provided on the housing 5, and a muffler 3 and a pneumatic assembly 4 are provided at the lower part of the housing 5. The pneumatic assembly 4 is in closed communication with the cavity. see figure 1 , Two pneumatic micro vibrators 2 are installed on the lower sand box, and the installation method is diagonal installation, so that the force on the lower sand box can be equalized, and there is no dead corner of vibration. see figure 2 with image 3 A sealing ring is arranged between the housing 5 and the cover plat...

Abstract

The invention relates to a pneumatic vibrator structure. The pneumatic vibrator structure comprises a lower sand box, an installation beam and a shell body. The installation beam is fixed to the lower sand box. The shell body and the installation beam are fastened together through a bolt. A cavity is formed in the shell body. A vibrating ring is installed in the cavity. A cover plate is arranged on the shell body. A silencer and a pneumatic assembly are arranged on the lower portion of the shell body. According to the pneumatic vibrator structure, sand mold compacting can be facilitated through vibration so that a uniform and compact sand mold can be produced.

Description

Technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a pneumatic vibrator structure. Background technique [0002] At present, the lower sand box on the molding machine on the market does not use a vibrator, and it is common that the molding sand cannot fill the cavity well, resulting in the sand mold being easily loosened in the transportation project, and the sand mold and the sand box are separated during the mold release Difficult to mold, easy to mold sticking phenomenon. In order to solve the above problems, it is necessary to design a miniature vibrator to improve product quality. Summary of the invention [0003] The present invention overcomes the shortcomings of the prior art and proposes a pneumatic vibrator structure, which can promote the molding sand to better flow into the grooves and cavities of the upper and lower sand molds, and through vibration, can help tighten Solid sand mold to produce a uniform ...
