The utility model is further set to: between described support bar and fixed bar, removably connect.
By adopting technique scheme, in the time that each parts of lower bolster are damaged, can be by the replacing that removably connects to realize boss or installation portion of support bar and fixed bar, easy to maintenance, do not need whole lower bolster all to change, in the time of boss or installation portion damage, the support bar being connected with the fixed bar on boss is disassembled, change after new boss or installation portion, then boss is connected with installation portion, simple to operate and reduce costs.
The utility model is further set to: described support bar is set on fixed bar.
By adopting technique scheme, the support bar of installation portion is to be set on the fixed bar of boss, and the relative displacement between support bar and fixed bar can change, the distance realizing between distance and adjacent two installation portions between boss and installation portion can be adjusted according to the size of injection mold, make the size of whole lower bolster adjustable, can be for multiple injection mold.
The utility model is further set to: described boss and fixed bar are wholely set, and described installation portion and support bar are wholely set.
By adopting technique scheme, fixed bar and boss are wholely set, installation portion and support bar are wholely set, strengthen the bond strength of junction between junction between fixed bar and boss and installation portion and support bar, strengthen the structural strength of lower bolster, improved operating efficiency simultaneously.
The utility model is further set to: the making material of described template body is stainless steel.
By adopting technique scheme, stainless steel has intensity height and good rustless property, and template body is made up of stainless steel, and antirust ability, anti-pressure ability and the structural strength of lower bolster are all strengthened greatly, has extended the service life of lower bolster.
The utility model is further set to: the through hole that forms several shapes triangular in shape between described boss and installation portion.
By adopting technique scheme, between boss and installation portion, be connected with fixed bar by support bar, form the through hole of several shapes triangular in shape simultaneously, saved the making material of lower bolster, and alleviated the quality of lower bolster, thereby alleviate the total quality of injection mold.
The utlity model has following advantage: between boss and installation portion and between adjacent two installation portions, all can realize scalable connection, and can removably connect, the size that realizes lower bolster is adjustable, thereby can be for the injection mold of different size size, practical.
