Abstract:
(EN) The invention is an injection cavity mold 20 for injection molding, provided with three or more cavity rows 22 in which a plurality of cavities 21 are formed, and provided with a cooling flow path 30 through which a cooling medium for cooling the cavities 21 is allowed to flow, wherein: the cooling flow path 30 is formed of at least one supply port 31, distribution tubes 32 communicating with the supply port(s) 31, supply tubes 33 communicating with the distribution tubes 32, cavity cooling units 34 that communicate with the supply tubes 33 and are provided to the outer periphery of the cavities 21, discharge tubes 35 communicating with the cavity cooling units 34, aggregation tubes 36 communicating with the discharge tubes 35, and at least one discharge port 37 communicating with the aggregation tubes 36; and the supply tubes 33 and the discharge tubes 35 are formed so as to be parallel to the cavity rows 22 and so that there is at least one of each for each of the cavity rows 22.
(FR) La présente invention concerne un moule de cavité d’injection (20) pour le moulage par injection, muni de trois rangées de cavités ou plus (22) dans lequel une pluralité de cavités (21) sont formées, et muni d’un trajet d’écoulement de refroidissement (30) à travers lequel un milieu de refroidissement pour le refroidissement des cavités (21) est laissé à s’écouler : le trajet d’écoulement de refroidissement (30) est formé d’au moins un orifice d’alimentation (31), de tubes de distribution (32) communiquant avec l’(les) orifice(s) d’alimentation(s) (31), de tubes d’alimentation (33) communiquant avec les tubes de distribution (32), d’unités de refroidissement de cavité (34) qui communiquent avec les tubes d’alimentation (33) et sont disposées au niveau de la périphérie externe des cavités (21), de tubes d’évacuation (35) communiquant avec les unités de refroidissement de cavité (34), de tubes d’agrégation (36) communiquant avec les tubes d’évacuation (35), et d’au moins un orifice d’évacuation (37) communiquant avec les tubes d’agrégation (36) ; et les tubes d’alimentation (33) et les tubes d’évacuation (35) sont formés afin d’être parallèles aux rangées de cavités (22) et de sorte qu’il y en ait au moins un de chaque pour chacune des rangées de cavités (22).
(JA) 複数のキャビティ21が形成されたキャビティ列22を3列以上備え、キャビティ21を冷却する冷却媒体を流通させる冷却流路30を備える射出成形用の射出キャビティ型20であって、冷却流路30は、少なくとも1つ以上の供給口31と、供給口31と連通された分配管32と、分配管32と連通された供給管33と、供給管31と連通されキャビティ21の外周に設けられたキャビティ冷却部34と、キャビティ冷却部34と連通された排出管35と、排出管35と連通された集約管36と、集約管36と連通された少なくとも1つ以上の排出口37と、により形成され、供給管31及び排出管35は、キャビティ列22に平行に、かつキャビティ列22毎にそれぞれ少なくとも1つずつ形成されている、射出キャビティ型20。
