Die Block Casting Specifications
GENERAL:
综述：
数控冲床模具
All die blocks must have sufficient stock allowance for machining .Tolerances for as cast surfaces to be per SFSA standard. Supplier will be responsible for verifying the dimensions from the drawing with the patterns supplied by Kokomo Casting Plant prior to manufacturing the blocks.
所有的模块必须具有足够的库存定额供加工生产。铸态表面公差可参考SFSA标准。供应商在制造生产那些模块前将负责核查Kokomo铸造厂提供的模型及图纸的尺寸规格。 Castings, which do not meet the quality requirements, specified in this specification, after machining, subsequent to its acceptance at the die builder, will be subjected for rejection. T
he supplier shall be responsible for the machining labor, cost for transportation, and replacement of the rejected die blocks.
那些不能达到这份说明所指定的要求的铸件，在加工生产后送交铸模建造商接收鉴定，之后将被退货。供应商将负责提供生产人员，运输成本和替换铸块。 Supplier to be responsible for the up-keep of patterns while they are at the supplier’s facility. Supplier is required to notify Chrysler Purchasing in Detroit when the patterns need to be repaired or replaced.
供应商将负责维护那些还在其生产设备里的模型。当那些模型需要修理或报废时，供应商被要求通知底特律的克莱斯勒采购。
Approval for salvage of cast blocks must be obtained from the Kokomo Tool Engineering Department prior to welding or repair. All die blocks will be stress relieved or quenched and tempered after welding, and the final hardness must be within the specified range.
在对模块进行焊接和修复前，维修经费的许可必须经由Kokomo设备工程部门审批。所有
的模块在焊接之后必须去除应力或淬火和回火，并且最后的硬度必须在规定的范围内。
Die blocks must have manufacturer’s logo, serial number, and the cast dates, cast on the non-machining surface as specified on the drawing. Casting drawings indicate an area for such information; however this is a suggested area only. The foundry using the following considerations can determine the actual location.
模块上必须有制造商的商标，序列号以及铸造日期等信息，浇铸在图纸指定的非加工面上。铸件图纸给出了这样一个信息区域，但这只是一个供参考的区域而已。铸造厂可根据下面的建议来确定实际的位置。
a. Must be located in a non-machined area.
b. Should be visible, with die in the die cast machine.
c. Serial number may be neatly engraved, stamped or cast.

自控温伴热带
a. 必须位于非加工区域上。
b. 必须可见，固定在压铸机上。
汽车整形
博物馆展柜制作c. 序列号可整齐地雕刻、印戳或浇铸。

Casting must conform to Chrysler specifications.
铸件必须符合克莱斯勒技术规范
Leave all handling rings and lugs on casting to aid in trucking castings. These rings and lugs will be removed when handling holes are installed.
铸件上应留有搬运用的吊环和吊耳以方便运输，这些吊环和吊耳将会在搬运孔安装后拆除。
Casting to be rough machined on the cope side to a flat surface leaving ample stock for finishing.
铸件的上模面将被粗加工成一个平面，并且留有足够的余量以便进行精加工。
All short line dimensions on casting layouts are taken from datum X=0, Y=0, Z=0.
铸件布局上的所有短线尺寸都是以X=0, Y=0, Z=0为基准。
Vendor to return patterns to Kokomo Casting Plant in good usable condition upon request.
供应商应在Kokomo铸造厂提出要求后归还模型并保证模型处于良好的使用状态。
Phantom lines representing finish-machined surfaces indicate surfaces needing machine stock. Basic guidelines for machine stock requirements:
虚线说明表面需要留有加工余量，虚线就代表精加工面的位置。确定加工余量要求的基本准则有：
a. .50” stock on all surfaces parallel to the parting line, except cope side of casting.
船舶智能焊接技术
除铸件上模面之外的所有平行于分型面的表面留50’’的余量。
b. .75” stock on all walls vertical to the parting line.
所有垂直于分型面的壁留75”的余量
c. Required drafted areas should favor additional machine stock.
有设计要求的部位应留有额外的加工余量。
Pattern and casting certification prints will be provided for pattern and casting layouts.
将会提供模型和铸件设计所需的书面证明。
MATERIAL & HEAT TREATMENT
材料 & 热处理
The material to be cast steel per AISI 8620 Type, water quenched and tempered to Brinell hardness between 210 to 250. This harness is required on the finished-machined surfaces of the die block.
材料应是符合AISI 8620类型的铸钢，水淬和回火后使其达到210~250的布氏硬度，模块精加工表面必须达到这个硬度。
Actual chemical composition will be agreed to by Chrysler and must be based on die block maximum heat treated cross section and desired mechanical properties.
实际的化学组成将由克莱斯勒公司商定，并且必须以模块热处理后的最大横截面及要求的机械性能为基础。
Vendor to furnish heat treat and material certification.
供应商将提供热处理及材料证明。
NONDESTRUCTIVE TESTING:
蒸压加气块无损检测
The casting to be inspected 100% with (A) Magnetic Particle Inspection (Dry), (B) Visual Inspection, (C) Hardness Testing, (D) Magnetic Particle Testing (Wet), (E) Ultrason
ic Inspection(optional), (F) Radiographic Inspection (optional),(G) Die Penetrate Inspection in selective area as optional testing methods. Tests shall be performed by an Inspector certified to a minimum level 2 in accordance with the American Society of Nondestructive Testing Guide line #ASNT-TC-1A.
