Problems solved by technology

However, the toggle mechanisms disclosed in these patents can only be driven by a power device to move a movable mold base connected to it. If several fixed mold bases and movable mold bases are installed on the injection molding machine to form several molding If the mold cavity needs to be matched with a corresponding number of power devices and toggle mechanisms, these molding mechanisms can be operated
This will lead to a bulky injection molding machine, which is not conducive to the miniaturization of the operation requirements

Embodiment Construction

[0014] In this embodiment, the toggle mechanism of the present invention is introduced in detail by taking a molding machine for molding aspherical glass lenses as an example.

[0015] The molding machine 1 of the present embodiment is provided with two molding chambers, i.e. an upper molding chamber 10 and a lower molding chamber 10', and each molding chamber (10 or 10') is equipped with molding molds (11) similar in structure. or 11'), the molding molds (11 or 11') located in the upper and lower molding chambers all have fixed mold bases (12 or 12'), movable mold bases (13 or 13'), and are installed on fixed mold bases (12 or 13'). 12') on the fixed mold core (14 or 14') and the movable mold core (15 or 15') installed on the movable mold base (13 or 13'), wherein the fixed mold base (12 or 12') is fixed On the fixed seat 100 of the molding machine; the movable mold base (13 or 13 ') is to be connected with a push rod (16 or 16 '), and the other end of the push rod (16 or 16 ...

Abstract

An elbow joint mechanism installed onto a shaping machine and driven by a power unit for dividing the drive force of power unit into at least two drive forces is composed of at least three pivoting units (one for power unit and two respectively for two parts on shaping machine), and two arms respectively arranged between two pivoting units.

Description

【Technical field】 [0001] The invention relates to a toggle mechanism, in particular to a toggle double-feed mechanism which can be applied to a multi-directional force output device or a locking device. 【Background technique】 [0002] It is quite common to apply toggle mechanisms to multi-directional output devices or locking devices. For example, on injection molding machines, toggle mechanisms can be used to push or pull back the movable mold base, in this way to achieve mold closing or opening. model action. In fact, a general injection molding machine mainly has a fixed mold base, a movable mold base, and a toggle mechanism connecting the power device (such as a pneumatic cylinder or hydraulic cylinder) and the movable mold base. During the injection molding process, the power device can Push the toggle mechanism to bend and close or open and straighten, and the other end of the toggle mechanism can drive the movable mold base to move together, that is, through the link...
