Abstract

The invention discloses a shell mold with a batch number sand core, a batch number mold and a batch number manufacturing method. A groove is formed in a position, which corresponds to a casting production batch number, in a shell mold body of the shell mold; the batch number sand core is embedded into the groove; a production batch number of a casting is formed on the outer side surface of the batch number sand core. The batch number manufacturing method comprises the steps of making the batch number sand core with the production batch number of the day through the batch number mold according to a plane of the day; embedding the batch number sand core into the corresponding groove of the shell mold, and then performing normal core assembling production. The groove matched with the batch number sand core only needs to be formed in the proper position on the shell mold with the batch number sand core, so that processing manufacturing of the batch number mold is simplified; furthermore, production batch number management is very convenient, and the production flow is simplified.

Description

A kind of shell mould, lot number mould and lot number preparation method of tool lot number core

Technical field

The invention belongs to Shell Casting Technology, relate in particular to a kind of shell mould, lot number mould and lot number preparation method of tool lot number core.

Background technology

Shell moulded casting is as a kind of sand mould casting method rising in recent years, high mainly for the production of dimensional accuracy, shows that roughness requires in high castings production.Its process characteristic is the sculpting methods such as the clay-bonded sand that uses precoated sand hot box to make foundry goods external mold core to replace traditional sand casting generally to use, resin sand, water-glass sand.Especially in nickelic and stainless steel turbine case castings production, obtained generally using, can large-scale mass production.

For the ease of the trackability of foundry goods, on foundry goods, directly casting out product batch number is a kind of good method, and general conventional way is in the time of coremaking, to change lot number word.But this method, owing to generally needing the time of 3-5 days from coremaking to casting, is not easy to organization of production very much.The core with lot number of often producing can not be with the casting of lot number date because of a variety of causes on core, has lost the meaning of reviewing.

Summary of the invention

The shell mould that the object of the present invention is to provide a kind of tool lot number core, it has the advantages that to be convenient to production and processing, makes to solve prior art medium casting the problem that product batch number exists.

Another object of the present invention is to provide a kind of lot number mould, it has simple in structure, is convenient to process the feature of lot number core, makes to solve prior art medium casting the problem that product batch number exists.

Another object of the present invention is to provide a kind of lot number preparation method, and it has the feature simply and easily of making, and makes to solve prior art medium casting the problem that product batch number exists.

For reaching this object, the present invention by the following technical solutions:

A shell mould for tool lot number core, it comprises shell mould body, wherein, in described shell mould body, on the position of corresponding castings production lot number, offers groove, described groove is embedded in lot number core, offers the product batch number of foundry goods on the lateral surface of described lot number core.

Especially, described groove is strip structure, and corresponding lot number core is also strip structure.

A kind of lot number mould, it comprises base plate, word board bracket, word board and type matrix frame, and wherein, described word board bracket is arranged in described base plate and both adopt matched in clearance, described word board is arranged in word board bracket and both adopt matched in clearance, and described word board bracket arranges type matrix frame outward.

Especially, between described word board and word board bracket, adopt the matched in clearance that one end is large, one end is little, be convenient to more transpose board and prevent that word board from dropping out in operation simultaneously.

A kind of lot number preparation method, it comprises the following steps:

1) the lot number core with product batch number on the same day that uses lot number mould to make according to the plan on the same day;

2) lot number core is embedded in shell mould corresponding recesses, then carry out normal core assembly production.

Beneficial effect of the present invention is, compared with prior art can realize the utmost point Lot number management in shell moulded casting easily, simplify production procedure, reduced the difficulty of sand mold warehousing management, stopped to answer band lot number sand mold that a variety of causes causes can not be on sand mold the lot number date water fluid origin sand mold and scrap.Owing to having used unified lot number core, lot number size, shape on foundry goods are unified, good product consistency simultaneously.

Detailed description of the invention

Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by detailed description of the invention.

Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of shell mould of tool lot number core comprises shell mould body 1, wherein, on the position of the interior corresponding castings production lot number of described shell mould body 1, offer the groove 2 of strip, described groove 2 is embedded in the lot number core 3 of strip, offers the product batch number of foundry goods on the lateral surface of described lot number core 3.

A kind of lot number mould comprises base plate 4, word board bracket 5, word board 6 and type matrix frame 7, wherein, described word board bracket 5 is arranged in described base plate 4 and both adopt matched in clearance, be convenient to word board bracket 5 to take out more transpose board from base plate 4, described word board 6 is arranged in word board bracket 5 and both adopt the matched in clearance that one end is large, one end is little, is convenient to more transpose board 6 and prevents that word board 6 from dropping out in operation simultaneously.The outer type matrix frame 7 that arranges of described word board bracket 5.

A kind of lot number preparation method, it comprises the following steps:

1) the lot number core with product batch number on the same day that uses lot number mould to make according to the plan on the same day;

2) lot number core is embedded in shell mould corresponding recesses, then carry out normal core assembly production, the core assembly production cycle is shorter, generally can accomplish core assembly on the same day, and the same day, cast was produced.

In the shell mould of above-mentioned tool lot number core, only need to make the groove matching with lot number core in applicable position, not only simplify the processing and fabricating of lot number mould; And be convenient to very much product batch number management; Simplify production procedure.

Above embodiment has just set forth general principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
