Description

Technical Field

[0001] The utility model belongs to the technical field of molding machines, and particularly relates to a structure of a molding machine for casting. Background Technique

[0002] A molding machine is used to compact the jolted sand mold again, and a sand mold with upper and lower compaction can be obtained. The working table drops and collides with the floating shock iron to slightly shock and compact the molding sand, and then compacts it. Its main functions are: filling sand, filling loose molding sand into the sand box; compacting the molding sand, making the loose molding sand in the sand box compact through different methods such as jolting, compressing, jolt-compressing, and shooting-compressing, so that the sand mold has the necessary strength during transportation and pouring, and then using different mechanisms to take out the pattern from the compacted sand mold.

[0003] The existing structure of the molding machine consists of a sand pressing mechanism, a casting mechanism, and a ejector rod mechanism. The sand core in the sand box is compacted through the sand pressing mechanism to achieve shaping. However, there are the following defects: (1) During the use of the existing structure of the molding machine, its ejector rod needs to be adjusted according to the actual position of the sand box to ensure the best ejection and demolding effect. However, in actual adjustment, the existing ejector rod is installed at its bottom with bolt fasteners and locked on the rectangular slider. When adjusting, first loosen the bolt fasteners, then slide and adjust the position, and then lock the bolt fasteners again. During the adjustment and locking process, the position of the ejector rod is prone to move, resulting in the problem of reduced accuracy of the adjusted position of the ejector rod. For this reason, we propose a structure of a molding machine for casting. Summary of the Utility Model
