Abstract

The present invention relates to casting technology field, specially a kind of manufacturing method of the profile-followed chill of type chamber makes wooden skeleton for producing the profile-followed chill for casting the thick big position atrium structure of G. Iron Castings；On standard workpiece identical with positional structure to be cast, inscription rubbing apotype is carried out to wooden skeleton with putty, obtains the inscription rubbing model being bonded completely with position to be cast；Inscription rubbing model is put into sandbox, sand washing, mould turnover takes out inscription rubbing model, obtains profile-followed chill type chamber；It is poured, obtains profile-followed chill.Easy to make, accurate size of the invention, can be bonded completely.

Description

The manufacturing method of the profile-followed chill of type chamber

Technical field

The present invention relates to casting technology field, specially a kind of manufacturing method of the profile-followed chill of type chamber, for producing use In the profile-followed chill of the thick big position atrium structure of casting G. Iron Castings.

Background technique

It is frequently encountered in casting field to avoid shrinkage porosite from needing the case where being laid with chill, general simple structure, is carried out When chill is laid with, conventional structure chill can basic fit type chamber moulding, but encounter the mutually more complex G. Iron Castings thickness of structure Big position atrium structure, such as when the casting of elevator machine cylinder inner face, atrium has the curve slope of six reinforcing ribs, such Situation is laid with that chill difficulty is larger, and a kind of technique can be avoided being not easy to be laid with place, carries out the laying of chill, this side in its vicinity Formula chill avoids the ineffective of shrinkage porosite；Another way is first to carve die model, then make profile-followed chill with die model, is made so not Only making chill shape that is inconvenient and producing, there are errors, are often not placed into.

Summary of the invention

In view of the defect of the prior art, the present invention provides a kind of manufacturing method of profile-followed chill of type chamber, is used to produce For casting the profile-followed chill of the thick big position atrium structure of G. Iron Castings, production method is simple and practical, obtained profile-followed chill ruler It is very little accurate.

In order to achieve the above objectives, the present invention proposes a kind of manufacturing method of profile-followed chill of type chamber, and specific step is as follows：

Step 1：Make wooden skeleton；

Step 2：On standard workpiece identical with positional structure to be cast, inscription rubbing apotype is carried out to wooden skeleton with putty, is obtained To the inscription rubbing model being bonded completely with position to be cast；

Step 3：Inscription rubbing model is put into sandbox, sand washing, mould turnover takes out inscription rubbing model, obtains profile-followed chill type chamber；

Step 4：It is poured, obtains profile-followed chill.

Further, the wooden skeleton in the step 1 is divided into several pieces of wooden skeleton components, several pieces of wooden skeleton groups Part is spliced into a wooden skeleton.

Further, the step 2 is to be smeared on wooden skeleton component with putty, is placed on later and position to be cast Inscription rubbing on the identical workpiece of structure is set, so that putty is bonded completely in position to be cast, completes the apotype to wooden skeleton component.

Further, the standard workpiece identical with positional structure to be cast is elevator machine cylinder；The position to be cast It is set to elevator machine cylinder inner face.

It is put using profile-followed chill obtained above, prepares moulding, in the thick big position of finally casting casting G. Iron Castings Cavity configuration.

Beneficial effects of the present invention：Easy to make, accurate size can be bonded completely.

Specific embodiment

With reference to the accompanying drawing, invention is further explained.

Embodiment 1

Elevator machine cylinder inner face, the i.e. curve slope of six reinforcing ribs are cast using profile-followed chill comprising the muscle of outermost Plate cambered surface, intermediate smoothly cambered surface 8 and the excessively cambered surface 9 of periphery between the two, periphery excessively cambered surface are handed over for concave surface 10 and convex surface 11 For the cambered surface of round and smooth transformation transition, a kind of manufacturing method of profile-followed chill of type chamber is proposed, it is characterised in that：Specific step is as follows：

Step 1：Make wooden skeleton 1；Wooden skeleton 1 divides for the excessively wooden skeleton 1.1 in four pieces of peripheries and a center cambered surface wood Matter skeleton 1.2, the excessively wooden skeleton 1.1 in four pieces of peripheries and the wooden skeleton 1.2 of a center cambered surface are spliced into a wooden skeleton 1。

Step 2：On standard workpiece 2 identical with positional structure to be cast, inscription rubbing is carried out to wooden skeleton 1 with putty 3 Apotype obtains the inscription rubbing model 4 being bonded completely with position to be cast；Specifically with putty 3 in each wooden skeleton group Part（The excessively wooden skeleton 1.1 in four pieces of peripheries and the wooden skeleton 1.2 of a center cambered surface）On smeared, be placed on later with wait cast Inscription rubbing on the identical standard workpiece 2 of positional structure is made, so that putty 3 is bonded completely in position to be cast, is completed to wooden skeleton Component（The excessively wooden skeleton 1.1 in four pieces of peripheries and the wooden skeleton 1.2 of a center cambered surface）Apotype.

Step 3：Inscription rubbing model is put into sandbox 5, sand washing, mould turnover, mould assembling takes out inscription rubbing model 4, obtain profile-followed chill type Chamber 6；

Step 4：It is poured, obtains profile-followed chill.

The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention, It should not be considered as limiting the scope of the invention.All changes and improvements made in accordance with the scope of the present invention, should all It still belongs within this patent covering scope.
