Double-station automatic molding machine

Abstract

The invention provides a double-station automatic molding machine, and belongs to the technical field of machines. The problems that an existing molding machine is unstable in working and not high inautomation degree are solved. The double-station automatic molding machine comprises a base, and the base is provided with a transversely-arranged fixing frame and a molding box pushing device longitudinally penetrating through the fixing frame; the two transverse ends of the fixing frame are both provided with mold pushing devices; the base is further provided with sand mold pushing devices; a sand hopper with a switch structure is arranged on the upper portion of a molding box; the fixing frame is fixedly connected with a supporting frame, the supporting frame is provided with a lifting mechanism driving the sand holler to do reciprocating displacement in the vertical direction, and after the lifting mechanism drives the sand hopper to descend, an outlet on the lower portion of the sandhopper stretches into an inlet of the molding box; and after the lifting mechanism drives the sand hopper to move upwards, the outlet on the lower portion of the sand hopper is separated from the inlet of the molding box. The double-station automatic molding machine further comprises two rows of sand mold traction devices which are located on the transverse extension cord of the sand mold pushingdevices correspondingly and used for conveying sand molds. The double-station automatic molding machine has the advantages of being high in automation degree and good in working stability.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a molding machine, in particular to a double-station automatic molding machine. Background technique [0002] The molding machine is a casting equipment used to make sand molds. Its main functions are: filling sand, filling loose sand molds into the sand box; The loose sand mold is compacted, so that the sand mold has the necessary strength during the process of handling and pouring; the mold is lifted, and the pattern is taken out of the compact sand mold by using different mechanisms. Sand mold manufacturing is the central link of the molding machine. In the past, manual mold loading and mold changing are used, but now automatic molding machines are used to save time and effort. [0003] For example, the applicant, as the inventor, designed a double-station horizontal automatic molding machine and applied for a patent [application number: 201810997307.1; application publication...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned double-station horizontal automatic molding machine doubles the efficiency of the standard molding machine through the double-station setting, but the position of the sand storage box is fixed, which makes debugging troublesome, and the bottom of the sand storage box is slightly far away from the molding box, resulting in sand It cannot completely enter the molding box, and the short distance will cause interference so that the molding box cannot be displaced. It is necessary to ensure that there is an appropriate distance from the bottom of the sand storage box to the top of the molding box. During use, it is affected by vibration, temperature, etc., which will cause the distance to change. Unable to complete the ideal sand shooting and core setting work, the work stability is not high, the service life is short, and it does not have the function of sand mold transportation, and the degree of automation is not high
