Abstract
Abstract The present invention relates to an injection moulding apparatus comprising: i) means for the supply of a mouldable material to be moulded; ii) a mould comprising at least first and second mould parts defining a mould cavity having the shape of the article to be moulded, said first and second mould parts being separable in a direction to allow for release of a mould article; and iii) one or more material injection points for the injection of mouldable material into the mould cavity; characterised in that said injection points are positioned within the mould, such that the axis of injection is transverse to the direction of the separation of the first and second mould parts.

Claim 1
Independent Claim
109 words
Injection moulding apparatus comprising: (i) means for the supply of a mouldable material to be moulded; (ii) a mould comprising at least first and second mould parts defining a mould cavity having the shape of the article to be moulded, said first and second mould parts being separable in a direction to allow for release of a mould article; and (iii) one or more material injection points for the injection of mouldable material into the mould cavity; characterised in that said injection points are positioned within the mould, such that the axis of injection is transverse to the direction of the separation of the first and second mould parts.
Claim 2
Dependent Claim
109 words
Injection moulding apparatus comprising: (i) means for the supply of a mouldable material to be moulded; (ii) a mould comprising at least first and second mould parts defining a mould cavity having the shape of the article to be moulded, said first and second mould parts being separable in a direction to allow for release of a mould article; and (iii) one or more material injection points for the injection of mouldable material into the mould cavity; characterised in that said injection points are positioned within the mould, such that the axis of injection is transverse to the direction of the separation of the first and second mould parts.
Claim 3
Dependent Claim
34 words
Apparatus as claimed in Claim 1 characterised in that the mouldable material is a plastics material and wherein the means for supply includes heating means for forming an injectable melt of said plastics material.
Claim 4
Dependent Claim
45 words
Apparatus as claimed in Claim 1 or Claim 2 characterised in that each point of injection of said material into said mould is in the side of the mould when considered with respect to the direction of separation of said first and second mould parts.
Claim 5
Dependent Claim
50 words
Apparatus as claimed in any one of the preceding claims characterised in that the supply means comprises a supply conduit of substantially annular cross-section; the central portion of which comprises a heating member for the supply of heat to the mouldable material to maintain said material at a mouldable temperature.
Claim 6
Dependent Claim
20 words
Apparatus as claimed in Claim 4 characterised in that a heated element extends into the conduit within the mould body.
Claim 7
Dependent Claim
30 words
Apparatus as claimed in Claim 5 characterised in that the supply conduit for the mouldable material is of substantially circular cross-section at the point of injection into the mould cavity.
Claim 8
Dependent Claim
39 words
Apparatus as claimed in Claim 5 or Claim 6 characterised in that the heated element extending into the conduit within the mould body is a metal element in heat conducting contact with the heating member of the supply means.
