Embodiment Construction

[0068] Hereinafter, based on the embodiments shown in the drawings, the present invention will be described in detail by taking an injection molding machine as an example.

[0069] Such as figure 1 As shown, the clamping device of the injection molding machine 1 is fixedly provided with a fixed die platen 2 on a fixed side on a base 18 . A fixed side mold 4 is installed on the fixed die platen 2 . The movable side die 5 facing the fixed side die 4 is attached to the movable die platen 3 on the movable side. The movable die table 3 is guided by the guide rail 19 laid on the base 18, and moves relative to the fixed die table 2 via a linear bearing. The movement of the movable die platen 3 (mold opening and closing movement) adopts the hydraulic cylinder 22 driven by hydraulic pressure.

[0070] In addition, in this embodiment, the support structure of the movable die platen 3 shows an example using the guide rail 19 and the linear bearing, but there is no problem using a guid...

Abstract

The aim of the invention is to provide a die-plate and an injection moulding machine which can realize optimization of strengthening structure of the die-plate, has enough strength, can realize light weight, can unsymmetrically form a cast hole for making rigidity of die mounting plate (31) side of a peripheral strengthening rib (36) higher than that of back plate (32), and specially increasing the rigidity of the necessary die mounting plate (31) effectively for realizing the optimization of the strengthening structure of the die-plate. So that, effective rigidity can be ensured by necessaryminimal ribs and substantial light weight of the die-plate can be realized without increasing more ribs than existing products, thereby reducing production cost of the die-plate (30) and lighting load of a driving mechanism for driving the movable die-plate.

Description

technical field [0001] The invention relates to a die platen, a mold clamping device and an injection molding machine on which a mold is installed. Background technique [0002] A fixed die platen on a fixed side and a movable die platen on a movable side are disposed opposite to each other on a mold clamping device of an injection molding machine or a die casting machine. The movable die platen is driven forward and backward in the direction of approaching and leaving relative to the fixed die platen through a hydraulic cylinder or the like. A mold on the fixed side is installed on the fixed die platen. A mold on the movable side is mounted on the side of the movable die platen. A molded article of a predetermined shape is formed by injecting resin or metal into a cavity formed between these fixed-side molds and movable-side molds. [0003] Among them, in the injection molding machine and the die-casting machine, there are large-scale fixed die platen and movable die pla...
