Problems solved by technology

However, in this method, because the steel nails face upwards and the salt core holes face downwards and are blind holes, when the salt core is fixed, the two holes need to be interspersed with the steel nails within a limited field of view, so the main disadvantage of this solution is the installation and fixing process Inconvenient and low efficiency, so that the high temperature salt core is exposed to the air for too long, it is easy to absorb water vapor in the air, and it is easy to produce casting defects such as pores during the casting process, which affects the casting quality

Abstract

The invention discloses a method and device for fixing a salt core for piston casting. The method comprises the following steps: positioning a connecting nail which comprises a tip and a self-tapping thread at the top end in a positioning hole of a casting mold, and sleeving the connecting nail with a supporting rod, wherein the connecting nail can be rotated in the positioning hole; placing the sale core at the top end of the supporting rod and positioning the salt core; and rotating the connecting nail to screw the tip of the connecting nail into the salt core. According to the above arrangement scheme, the method provided by the invention can avoid the adverse impact of fixing of the salt core on the structure of a casting part based on the fact that the salt core can be quickly and conveniently mounted on the mold.

Description

technical field [0001] The invention relates to the technical field of casting, and more specifically, relates to a fixing method and a fixing device for a piston casting salt core. Background technique [0002] The inner cooling oil channel of the piston is generally formed by using high temperature resistant industrial salt as the mold core during the casting process. Because the salt core is difficult to fix in the mold, the salt core is often impacted by the molten metal and buoyancy during the casting process. Floating occurs due to the effect, so that the position of the produced oil passage cannot meet the design requirements. [0003] In the prior art, in order to ensure that the salt core can be reliably fixed in the mold, it is usually achieved in the following two ways: [0004] For the first one, please refer to figure 1 , Both the salt core 1 and the support rod 2 are provided with through holes, and the steel nail 3 passes through the through holes on the sal...
