2、rd and comes into effect on 15 July1998 BSI 05-1999 ISBN 0 580 30167 2 National foreword This British Standard reproduces verbatim ISO6753-2:1998 and implements it as the UK national standard. The UK participation in its preparation was entrusted to Technical Committee MTE/12, Tools for pressing and

3、 moulding, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and

4、promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under t

The work of preparing International Standards is normally carried out through ISO technical commit

10、tees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the In

11、ternational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75% of the member

12、 bodies casting a vote. International Standard ISO6753-2 was prepared by Technical Committee ISO/TC29, Small tools, Subcommittee 8, Tools for pressing and moulding. Together with ISO6753-1, it cancels and replaces ISO6753:1982, which has been technically revised. ISO6753 consists of the following pa

13、rts, under the general title Tools for pressing and moulding Machined plates: Part 1: Machined plates for press tools, jigs and fixtures; Part 2: Machined plates for moulds. Descriptors: Moulding equipment, tools, plates, form specifications, dimensions, designation.BSISO6753-2:1998 BSI 05-1999 1 1

14、Scope This part of ISO6753 specifies the dimensions and tolerances, in millimetres, of machined plates for moulds of the following types: type A: clamping plates; type B: cavity plates; type C: intermediate plates; type D: ejector plates; type E: risers. It gives guidance relative to materials and h

15、ardness and specifies the designation of machined plates in accordance with this part of ISO6753. 2 Dimensions 2.1 Clamping plates (type A), cavity plates (type B) and intermediate plates (type C) See Figure 1 and Table 1. 2.2 Ejector plates (type D) and risers (type E) assigned to the size of plate

16、s See Figure 2 and Table 2. 2.3 Tolerances, limit deviations and surface roughness See Table 3. 3 Material and corresponding hardness The material and hardness are left to the manufacturers discretion. 4 Designation Machined plates for moulds in accordance with this part of ISO6753 shall be designat

17、ed by a) “machined plate”; b) reference to this part of ISO6753, i.e.ISO6753-2; c) its type (A, B, C, D or E); d) its length, l 2 , in millimetres (for types A, B orC), or its length l 1 , in millimetres (for types D or E); e) its length, l 1 , in millimetres (for types A, B or C), or its width b or

18、 b 1 , in millimetres (for types D or E); f) its thickness t 1 , t 2or t 3 , in millimetres; g) its class (I or II). EXAMPLE 1 The designation for a machined plate of type A of length l 2= 96mm, length l 1= 120mm, thickness t 1= 12,5mm and of class I is as follows: Machined plate ISO6753-2 A 96 120
