MOULD FOR FLASH-FREE MOULDING Russian patent published in 2013 - IPC B30B15/02 B29C45/26 

FIELD: process engineering.

SUBSTANCE: invention relates to production of articles from polymer materials, fusible metals and alloys with reinforced parts. Proposed mould consists of female and male dies, gate system, forming insert and resilient holder. Said holder serves to level and lock armature relative to mould in its closure. At least, one of the main parts has recesses for access of moulding material to resilient clamp. Note here that additional pressure is created to resilient clamp for it to take up the shape that rules out flash formation at armature parts extending beyond dimensions of formed part. Elastic coating is applied to connecting surfaces of male and female dies and forming insert. Said coating prevents penetration of moulding material into gaps in mould closure.

EFFECT: higher quality of finished parts.
