SPECIFICATION FOR PATTERN PLATES FOR MACHINE
MOULDING BOXES
( First Revision )
0. FOREWORD
0.1 This Indian Standard (First Revision ) was adopted by the
Indian Standards Institution on 30 December 1975, after the draft
finalized by the Foundry Sectional Committee had been approved by
the Structural and Metals Division Council.
0.2 This standard was first published in 1968 keeping in view TS
: 1280-1967 ‘ Specification for foundry moulding boxes of steel
construction ‘. Since IS : 1280 has been revised, it has been
decided to align this standard also with the revised version of IS
: 1280.
0.3 For large production of castings in a foundry, moulding
machines are employed and the patterns are mounted on plates with
runners and risers attached. These plates are known as pattern
plates. For snap flask work on squeeze machines the pattern plate
may be double-sided, that is, carry the drag portion of the pattern
on one side and the cope portion on the other side. Larger patterns
are mounted on one side only of the pattern plate, one machine may
be making drags and another copes.
0.4 For the purpose of deciding whether a particular requirement
of this standard is complied with, the final value, observed or
calculated, expressing the result of a test or analysis, shall be
rounded off in accordance with IS : 2-1960”. The number of
significant places retained in the rounded off value should be the
same as that of the specified value in this standard.
1. SCOPE 1.1 This standard covers the requirements for pattern
plates for machine moulding boxes.
~__s_ *Rules for rounding off numerica values ( revised ).

IS : 4604 - 1975
2. SUPPLY OF MATERIAL
2.1 General requirements relating to the supply of pattern
plates shall conform to IS : 1387-1967*.
3. MANUFACTURE
3.1 The pattern plates shall be manufactured according to
foundry’s requirements from grey cast iron, cast aluminium alloy
and lined with soft, light or heavy metal.
3.2 When cast in grey iron, the material shall conform to the
requirements of Grade 20 of IS : 2 10-I 9701, and when cast in
aluminium alloy it shall conform to Grade A-24 of IS : 617-1975:.
In case wood is used for making pattern plates, the quality of wood
used, and design of plate shall be as agreed to between the
purchaser and the manufacturer. Further lining material shall be
used according to purchaser’s requirements.
4. SHAPE AND SIZE
4.1 The shape and size of pattern plates shall be in accordance
with Table 1. The size of the pattern plate to be specified in the
order shall include length, breadth, thickness and height of the
pattern plate ( II, bl, t and h, see Table 1 ).
4.1.1 The thickness t and height h of the pattern plate shall
depend on the type and height of the mould and shall be mentioned
in the order.
4.1.2 Top and bottom surfaces of pattern plates shall be
machined true and parallel.
4.2 If required by the purchaser, round and polygonal pattern
plates may also be supplied. The dimension ( 11) shall then
correspond to the dia- meter of the round plate and the diameter of
the inscribed circle in the case of polygonal pattern plates.
5. PIN CENTRES
5.1 The distance between pin centres ( 1s ) shall be as shown in
Table 1.
5.2 The holes for the pins in the lugs shall be jig drilled to
diameter d as given in Table 1. The tolerance on pin centre
distance shall be not more than f0’5 mm.
6. LUGS
6.1 The minimum dimensions of lugs shall be as shown in Table
1.
*General requirements for the supply of metallurgical materials
(&first reuision ). $ipecification for grey iron castings (
second reuision ). fSpccification for aluminium and aluminium alloy
ingots and castings for general
engineering purposes ( seconll rcvi~ion ). . .

7.1 Ribs of suitable size shall be provided in the plates taking
into consi- deration the size of the plate and the material of
construction. When the pattern plates are made of grey iron, the
ribs shall be of thickness ( t2 ) as given in Table 1. The ribs
shall be slightly tapered on both sides and corners rounded. The
distance between the two ribs shall be between 175 and 225 mm.
8. CLAMPING ARRANGEMENT
8.1 Clamping or fixing arrangement of the pattern plates and the

NOTE -The use of the IS1 Certification Mark is governed by the
provisions of the Indian Standards Institution ( Certification
Marks ) Act and the Rules and Regulations made thereunder. The IS1
Mark on products covered by an Indian Standard conveys the
assurance that they have been produced to comply with the
requirements of that standard under a well-defined system of
inspection, testing and quality control which is devised and
supervised by IS1 and operated by the producer, ISI marked products
are also continuously checked by IS1 for conformity to that
