Embodiment Construction

[0031] The solution of the present invention will be described below in conjunction with the accompanying drawings.

[0032] refer to Figure 1 to Figure 6 , shows a sand core assembly jig for boxless molding according to the present invention, which includes at least two sets of jig subassemblies. The fixture subassembly includes an assembly base plate 1 and an assembly cover plate 2, each of which includes a pair of square steel pipes arranged in parallel, and the pair of square steel pipes are spaced apart by a first distance and at the ends The upper and lower sides of the place are welded together by connecting steel plates, thereby defining a first gap between the pair of square steel pipes. The clip subassembly also includes four spacers 4 formed by welding a clip nut 5 at the center of a circular steel plate with a hole, the diameter of which is equal to or greater than that of the clip. The diameter of the threaded hole of clamping nut 5, so as not to interfere with...

Abstract

The invention provides a sand core assembling clamp for removable-flask molding. The sand core assembling clamp comprises at least two clamp subassemblies. Each clamp subassembly comprises an assembly bottom plate and an assembly cover plate, wherein the assembly bottom plate and the assembly cover plate each comprise a pair of square steel pipes arranged in parallel, the pair of square steel pipes are arranged at the interval of the first distance and welded together at the upper face and the lower face of the end through a connection steel plate, and therefore a first gap is defined between the pair of square steel pipes. Each clamp subassembly further comprises four gaskets and two clamping screw rods matched with clamping nuts and provided with threads, wherein the two clamping screw rods are extended on the two sides of a sand core to penetrate through the first gap between the assembly bottom plate and the assembly cover plate and are in tightened fit with the gaskets below the assembly bottom plate and the gaskets above the assembly cover plate, and therefore the sand core is clamped between the assembly bottom plate and the assembly cover plate. The invention further provides a using method of the sand core assembling clamp for removable-flask molding. The sand core assembling clamp can be reused and is high in utilization rate, and the production cost is reduced.

Description

technical field [0001] The invention relates to a sand core assembly jig for boxless molding and a method for using the same. Background technique [0002] Boxless molding is the preferred process for multi-variety, small-batch and complex casting production units to improve the grade of casting products. It can obtain high-grade castings without increasing tooling or even reducing tooling investment. But the current mature boxless shape has certain limitations: [0003] First of all, the model must be equipped with a mold plate and a sand frame. Generally, the model should be fixed on the mold plate. The pouring system and riser system are made according to the process requirements. The mold plate is used as a positioning pin, and the sand frame can be made into a fixed bucket according to the mold box. Shaped or flexible rectangular; [0004] Secondly, when molding the outer model box, place steel bars in the molding sand as the frame of the box, and the box that needs t...
