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 ).

3

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. RIBS

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 position and size of flanges for introducing vibrators shali be as agreed to between the purchaser and the manufacturer.

9. MARKING

9.1 Each pattern plate shall be marked with the manufacturer’s name or trade-mark and the size of the pattern plate.

9.1.1 The pattern plates may also be marked with the IS1 Certification Mark.

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 standard as a further safeguard. Details of conditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.
