3.1.1

injection moulding machine

machine for the cyclic production of moulded parts from plastics and/or rubber

Note 1 to entry: The material is injected through a nozzle into a mould (3.1.2) containing one or more cavities in which the article is formed.

Note 2 to entry: An injection moulding machine essentially consists of one or more clamping units (3.1.6) , one or more injection units (3.1.8) , drive and control systems.

Note 3 to entry: Examples of horizontal and vertical injection moulding machine are shown in Annex A.

3.1.2

mould

exchangeable part consisting of two or more halves clamped on the platens of the machine in which the material is injected

3.1.3

ejector

driven component (e.g. pin with linear movement) inside a mould (3.1.2) used for the ejection of the moulded part(s) out of the opened mould

3.1.4

core

driven component inside a mould (3.1.2) for carrying out mould functions, e.g. enabling undercuts in the moulded part

3.1.5

mould area

area between the platens where the mould (3.1.2) is fixed

3.1.6

clamping unit

part of the machine that holds, opens and closes the mould (3.1.2)

3.1.7

clamping mechanism area

area which comprises mechanisms for the movement of the movable platen and/or the application of the clamping force

3.1.8

injection unit

unit for processing (plasticizing and/or homogenizing) and delivering material through a nozzle

3.1.9

carousel machine

machine consisting of two or more clamping units (3.1.6) mounted on a carousel in either a vertical or horizontal configuration to index on one or more fixed injection units (3.1.8)

3.1.10

shuttle-table machine

machine with a sliding table/platen

machine designed to contain one or more parts of moulds (3.1.2) attached to a sliding table/platen

Note 1 to entry: The table/platen indexes the parts of the mould by a sliding movement between the loading/unloading station and the injection position.

3.1.11

turn-table machine

machine designed to contain one or more parts of moulds (3.1.2) attached to a rotating table

Note 1 to entry: The table indexes the parts of the mould by a rotary movement between the loading/unloading station and the injection position.

3.1.12

multi-station machine with mobile injection unit

machine consisting of a mobile injection unit (3.1.8) which indexes between two or more stationary clamping units (3.1.6)

3.1.13

ancillary equipment

equipment which interacts with the injection moulding machine (3.1.1)

Note 1 to entry: Examples are pick and place device, robot, mould changing equipment, mould clamping system or conveyor.

3.1.14

cellular foam injection moulding

injection moulding which involves either an entrained gas mixed into the melt or a granulate containing a foaming agent to achieve a cellular-structured product

3.1.15

electrical axis

axis where the primary movement of the axis is initiated by electrical energy

3.1.16

hydraulic axis

axis where the primary movement of the axis is initiated by hydraulic energy

3.1.17

standstill

condition under which there is no movement of a machine part

Note 1 to entry: See Figure 6 for the relation of standstill, safe standstill (3.1.18) , stopping (3.1.19) , safe stopping (3.1.20) and overall system stopping performance (3.1.21) .

3.1.18

safe standstill

standstill (3.1.17) during which unexpected start-up is prevented

Note 1 to entry: See Figure 6 for the relation of standstill , safe standstill, stopping (3.1.19) , safe stopping (3.1.20) and overall system stopping performance (3.1.21) .

3.1.19

stopping

deceleration of a movement of a machine part until standstill (3.1.17) is achieved

Note 1 to entry: See Figure 6 for the relation of standstill , safe standstill (3.1.18) , stopping, safe stopping (3.1.20) and overall system stopping performance (3.1.21) .

3.1.20

safe stopping

controlled stopping (3.1.19) and following standstill (3.1.17) during which a hazardous situation is prevented

Note 1 to entry: See Figure 6 for the relation of standstill , safe standstill (3.1.18) , stopping , safe stopping and overall system stopping performance (3.1.21) .

3.1.21

overall system stopping performance

time interval between the actuation of the sensing function and until standstill (3.1.17) is achieved

3.1.22

safety-related input

input to a motor control unit activating the safety function related to the drive of the electrically driven axis

3.1.23

operating position

position in front of the mould area (3.1.5) where the operator typically stands

3.1.24

automatic mode

selectable mode of operation that runs one or more cycles continuously

3.1.25

semi-automatic mode

selectable mode of operation that runs a single cycle and then stops

3.1.26

manual mode

selectable mode of operation that allows manual activation of individual movements
