Abstract
A method for suspending a chilling block on the resin sand molding cavity wall comprises the following steps that a, the chilling block is fixed to the inner wall of a resin molding cavity core mold or the outer wall of a resin female mold core mold, and gaps are reserved between the chilling block and the upper inner surface of a sand box and between the chilling block and the lower inner surface of the sand box; and b, the resin sand box is filled with resin sand, the resin sand is moved out of the resin molding cavity core mold or the resin female mold core mold after being cured, and the chilling block is fixed to the side wall of the resin molding cavity core mold or the side wall of the resin female mold core mold. The method has the technological effects that the chilling block is suspended inside the wall of a casting cavity, the problem that shrinkage holes are likely to be formed in the side face of a casting during mechanical production is solved, the number of hollows is decreased, forming of fixing screw holes in the portion is not affected, and the qualified rate of castings is increased.
Description
Technical field
The invention belongs to metal casting industry, be specifically related to a kind of foundry goods base substrate chill being suspended in method on resin sand die cavity wall and manufacture thereof.
Background technology
The method of present machinery casting housing is: according to casting design resin type core mold and resin female mold, produces resin core and resin former thus, and resin core and resin former form foundry goods casting cavity.But the shell arm difference in thickness of some housing is comparatively large, and the speed that foundry goods cools in cooling procedure is inconsistent, and loose and contracting hole appear in the position causing arm thick, cause foundry goods defective.Just need in resin mold, establish chill to accelerate the thick position cooling of arm, to solve the casting defect that cooling velocity difference causes.But the mode of existing placement chill is and is arranged on the upper and lower inner surface of resin sand box, then potting resin sand.This situation chill can only be the chill that inner surface upper and lower with resin sand box contacts, if in the method that resin madial wall suspension (suspending: have gap with the upper and lower inner surface of resin sand box) chill does not solve at present, such as N350 reducer shell, need to arrange fixing threaded hole in the side of this housing, the wall thickness at the position of fixing threaded hole is set, easily cause contracting hole, the method also do not solved at present.
Summary of the invention
The object of this invention is to provide a kind of foundry goods base substrate chill being suspended in method on resin sand die cavity wall and manufacture thereof.
Technical scheme of the present invention is specially:
Chill is suspended in the method on resin sand die cavity wall, comprises the following steps:
Step a, fixes chill at resin die cavity core mold inwall or resin former core outer wall, and the upper and lower inner surface of this chill distance sandbox keeps gap;
Step b, potting resin sand in resin sand box, after resin sand solidification, shift out resin die cavity core or resin female mold, chill is fixed on the sidewall of resin die cavity core or resin female mold.
Described resin type core mold inwall is provided with high temperature magnet at the position of fixing chill, by the magnetic force of high temperature magnet, chill is fixed; Or,
Described resin former core outer wall is provided with mounting projection at the position of fixing chill, and chill is provided with the locking site coordinated with this locking site.
The resin sand foundry goods base substrate manufactured by said method, is included in the foundry goods cavity of resin core and the formation of resin former, this foundry goods cavity wall inner suspension chill.
Technique effect of the present invention: at foundry goods cavity wall inner suspension chill, solve the problem easily occurring contracting hole in machinery production medium casting side, hollow out is reduced, do not affect and fixing threaded hole is set at this position, improve the qualification rate of foundry goods.

Detailed description of the invention
Embodiment 1: as shown in Figure 1, N350 reducer shell 1 is provided with side 2, and side 2 needs to arrange fixing threaded hole.Side 2 place needs to add chill, cannot add chill because position is special with conventional methods machinery.So add mounting chill 4.
As shown in Figure 2, mount chill 4 and be provided with locking site 5.
As shown in Figure 3, N350 resin former core 8 is provided with mounting projection 9.
When processing N350 resin former, the locking site 5 of mounting chill 4 is articulated on the mounting projection 9 of N350 resin former core 8, chill 4 is suspended in the sandbox of N350 resin former core 8, and the upper and lower inner surface of sandbox there is gap, does not contact.
Then potting resin sand in sandbox, shifts out N350 resin former core 8 after resin sand solidification, is also fixed in the inwall of resin former because the bonding force of resin sand and mounting chill 4 mounts chill 4 compared with ambassador.
Rely on prior art, then with fixing the resin former mechanization production line balance N350 reducer shell of mounting chill 4.Mounting chill 4 can be accelerated to cool side 2, to solve the problem of the casting defect that cooling velocity difference causes.
Embodiment 2:
As shown in Figure 4, a kind of ZN reducer shell 11 is provided with side 12, and side 12 needs to arrange fixing threaded hole.Side 2 place needs to add chill, cannot add chill because position is special with conventional methods machinery.So add built-in chill 14.
As shown in Figure 5, built-in chill 14 is adsorbed on magnet 15.
When processing ZN reducer shell core, be fixed on by magnet 15 on the inwall correspondence position of core sandbox, built-in chill 14 is adsorbed on magnet 15, makes built-in chill 14 be suspended in the sandbox of ZN reducer shell core, the inner surface upper and lower with sandbox has gap, does not contact.
Then potting resin sand in sandbox, shifts out ZN reducer shell core, because the bonding force of resin sand and built-in chill 14 is greater than the magnetic force of magnet 15 to built-in chill 14, built-in chill 14 is also fixed in the inwall of resin former after resin sand solidification.
Rely on prior art, then with fixing the resin core mechanization production line balance N350 reducer shell of built-in chill 14.Built-in chill 14 can be accelerated to cool side 12, to solve the problem of the casting defect that cooling velocity difference causes.
Present invention process is simple, is applicable to mechanization production.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under general idea prerequisite of the present invention; some changes and improvements can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
