Abstract
A specialized mould locking device for injection moulding machine is provided, which comprises a mould locking oil cylinder, a rear mould board, a hook ream, a long ream, a small ream, a crosshead, a movable mould board and a pull rod. The utility model, which is provided with a special machine ream parameter, enlarges the amplification coefficient of machine ream, so that, in comparison with injection moulding machine of similar mould locking force and hydraulic system, the utility model has less oil cylinder thrust, thus the diameter of the mould locking oil cylinder can be smaller and the speed for mould locking can be faster. Besides, the special machine ream parameter of the utility model makes the travel for mould locking and opening shorter and further reduces the cycle for the forming of products, thus enhancing the production efficiency. What is more, because drum-shape reinforcement bar is adopted to enhance the rigidity and strength of the movable mould board, the utility model is appropriate for working for a long time under the condition of high working frequency.
Description
Affiliated technical field
The utility model relates to a kind of clamping apparatus of special-purpose injection machine.
Background technology
The toggle type mould clamping system of existing general injection machine, its opening stroke of bigger clamp force is also bigger, big its product molding cycle of line Cheng Yue of unblanking under the equal velocity conditions is just long more, often need bigger clamp force and product molding cycle request weak point for producing some shallow chamber goods as nylon cable tie and DVD box and so on, the product molding cycle request is short just to mean that the operating frequency of machine can be very fast, this just need do further reinforcement to the rigidity and the intensity of machine, and existing general injection machine can't satisfy above these requirements.
Summary of the invention
Technical problem to be solved in the utility model: a kind of toggle type mould clamping system of special-purpose injection machine is provided, and this device makes it can produce some shallow chamber goods efficiently by designing a kind of special machine hinge parameter and special template structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of toggle type mould clamping system of special-purpose injection machine, it comprises Mode-locking oil cylinder, rear pattern plate, hook hinge, band andgudgeon, little hinge, crosshead, moving platen, pull bar etc., this device increases the amplification ratio coefficient of machine hinge by designing a kind of special machine hinge parameter, relatively the thrust of its Mode-locking oil cylinder can be littler with the injection machine of equal clamp force and hydraulic system, the diameter that also just means Mode-locking oil cylinder can be littler, and locked mode speed can be faster; This installs this special machine hinge parameter makes its line journey of unblanking shorter, can further shorten the molding cycle of goods; The moving platen of this device adopts the cydariform muscle to strengthen its rigidity and intensity, makes this device can be suitable for working long hours under the very high operating mode of operating frequency.
