Embodiment Construction

[0032] Next, examples of the best mode for carrying out the present invention will be described with reference to the injection molding machine of the accompanying drawings. Today, the present invention is not limited to injection molding machines but also includes die casting machines, and can be easily applied to devices other than those described in the examples within the range not departing from the gist of the invention. In the following description, an application example of a toggle mechanism applied to an injection molding machine will be described as an example.

[0033] In the specification of this application, the front-back, up-down, and left-right directions used refer to figure 1 direction shown. For the forward-backward direction, in figure 1 In , the direction toward the mold (right side) is referred to as the front, and the left side is referred to as the rear. The up and down direction refers to figure 1 In the up and down direction, the left and right d...

Abstract

To provide a molding machine provided with a tailstock capable of ensuring the rigidity of a connection part of a toggle link mechanism. A molding machine is provided with a tailstock for connection with a toggle link mechanism that causes a movable die plate to advance or retreat. The tailstock has a box shape composed of a front rectangular part and a rear rectangular part formed by integrally connecting together two upper and lower horizontal beams arranged vertically and extending horizontally and two left and right vertical beams arranged to the left and right and extending vertically. The tailstock has tie bar insertion holes formed at four corners of the front rectangular part and the rear rectangular part, and a plurality of plate-shaped toggle link connection parts formed to connect the toggle link mechanism. Built-up portions are provided on lateral surfaces of the toggle link connection parts and between adjacent toggle link connection parts.

Description

technical field [0001] The present invention relates to a molding machine such as an injection molding machine or a die-casting machine equipped with an elbow-type mold clamping mechanism. In particular, it relates to a molding machine provided with a tailstock capable of maintaining light weight and high rigidity. Background technique [0002] Molding machines such as injection molding machines and die-casting machines often have a fixed platen and a movable platen. A fixed mold is installed on the fixed formwork. A movable mold is installed on the movable template. The movable formwork is connected with the tailstock through a telescopic drive device such as a toggle mechanism or a cylinder. The driving device pushes the movable template to move to the side of the fixed template, so that the movable mold abuts against the fixed mold. Furthermore, the driving device presses the movable template to generate mold clamping force. Molten resin or molten metal is injected i...
