Definitions
- An auxiliary injection unit for a mould for forming plastics articles having at least two components
- the present invention relates to an auxiliary unit for plastics injection moulds for forming plastics articles having at least two components .
- moulded plastics articles having at least two components with different characteristics by the following method: initially one component, usually the main component having a predominant volume or weight:, is formed in a pre-arranged main mould into which the one component is injected by means of plastics injection moulding machines.
- the main object of the present invention is therefore that of resolving the technical problem indicated by eliminating the disadvantages of the prior art and devising an auxiliary unit which can be easily and rapidly fitted to a main mould.
- a further important object is that of providing an auxiliary unit in which the interconnection to the main mould also allows the achievement of a correct positioning for the injection of the second component of plastics material into the main mould without requiring the installer to exercise any precision in performing the coupling operation.
- Another important object is that of providing an auxiliary unit which is easily removable for maintenance and/or replacement.
- an auxiliary injection unit for fitting to one side of a mould for forming articles of plastics material and including at least one connection for the injection of a further plastics material component, which is characterised in that the said unit has at one end a plate which can be fitted slidably to a slide formed in the said at least one connection.
- Figure 1 illustrates, in a three-quarter side view, an auxiliary unit associated with a main mould
- Figure 2 illustrates a detail from a different view showing the end of the auxiliary unit interconnected to the main mould
- Figure 3 is a view taken on the section line III-III of Figure 2.
- the reference numeral 1 indicates an auxiliary injection unit and the reference numeral 2 indicates a mould in one side of which there is at least one connection 3 for allowing the introduction of a component from the auxiliary unit into the mould itself.
- This latter further has known channels and devices such as slides or others, able to allow the production, in successive stages, of products or articles of plastics material having at least two components.
- the auxiliary unit 1 has suitable first channels 4 for the introduction of the component into the mould 2, which first channels can be put into communication with second channels 5 formed in the connection 3.
- auxiliary unit 1 At one end of the auxiliary unit 1 there is a plate 6 of essentially C-shape, the base 7 of which is fixed to the said end close to the nozzle 8 of the auxiliary unit 1.
- the plate 6 has a pair of identical lugs 9a, 9b which are slidably engageable in correspondingly shaped guides 10a, 10b formed on a slide 11 present on the connection 3.
- the length and shape of the lugs 9a, 9b is such as to allow an interconnection between the plate 6 and the slide 11 such as to bring the first channels 4 of the auxiliary unit 1 into register with the second channels 5 present on the connection 3, thus allowing, when the auxiliary unit is fitted, the component to flow into the mould 2.
- the slide 11 is inclined with respect to a flat surface 12 of the mould 2 such as to allow an inclined arrangement of the auxiliary unit 1.
