Embodiment Construction
[0039] Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. The form and size of each element in the drawings are merely examples, and do not reflect the actual form and size.
[0040] The present invention is based on the technical idea that the resulting sprue bush is formed by at least two parts (a base part and a molding part). The "base" referred to here essentially refers to the existing sprue sleeve. Since the base is essentially an existing sprue bush, the base can be used as a part for injection molding without providing another part (molding part) on the base body. Nonetheless, the present invention is characterized in that the resulting sprue sleeve is intentionally formed by at least two parts (the base and the moulding).
[0041] like figure 1 As shown, the sprue bush 100 which concerns on one Embodiment of this invention can be obtained by combining the base part 100A and the shaping|mol...
