Abstract

The utility model relates to a dual-screw-rod and dual-motor synchronous driving device of an injection molding machine, wherein the dual-screw-rod and dual-motor synchronous driving device of the injection molding machine comprises a shoot table back plate and a screw rod driving component; two completely identical screw rods are installed at the left and right symmetrical parts of the shoot table back plate; the screw rods are fixed on the shoot table back plate through a bearing seat; and one ends of the two screw rods are both provided with two groups of synchronous belt wheels, wherein one group of synchronous belt wheels are connected through a synchronous belt, and the other group of synchronous belt wheels are connected with respective motors through corresponding synchronous belts. Because a group of synchronous belt wheels are connected through the synchronous belt, two screw rods can rotate synchronously; and two motors provide driving force synchronously, therefore, low-power motors and low-load screw rods are adopted, cost can be lowered greatly, and the structure is simplified.

Description

Injection machine mariages thick stick bi-motor synchronous drive device
Technical field
This practicality relates to a kind of injection structure of injection machine puts, and specially refers to a kind of mariages thick stick bi-motor synchronous drive device of injection machine.
Background technology
At present the injection mechanism of injection machine all adopts the monofilament thick stick to drive, and comprises as the one of which penetrating plate and leading screw good luck mechanism behind the platform.The monofilament thick stick driving mechanism that adopts has all proposed high requirement to the function of leading screw bearing capacity and motor under the prerequisite that injection force constantly increases, bring improving constantly of cost thereupon.And under the jejune prerequisite of technology, the monofilament bumper structure still can't provide corresponding injection force.
Summary of the invention
This practicality provides a kind of mariages thick stick bi-motor synchronous drive device in view of the above problems, solves the serial problem that is caused because of monofilament thick stick stand under load scarce capacity, reduces cost simultaneously, simplified structure.
This practicality solves the problems of the technologies described above the technical scheme that is adopted:
Injection machine mariages thick stick bi-motor synchronous drive device; Comprise and penetrate plate behind the platform, leading screw driven unit; Two duplicate leading screws are installed in position, symmetrical place, the plate left and right sides after penetrating platform, and leading screw is fixed on through bearing block and penetrates behind the platform on the plate, and an end of two rhizoid thick sticks is all installed two groups of synchronous pulleys; Wherein one group of synchronous pulley connects through band synchronously, and other one group of synchronous pulley is connected with separately motor through the corresponding synchronous band.
Because one group of synchronous pulley is through band connection synchronously, therefore two rhizoid thick sticks can rotate synchronously.By two motors driving force is provided simultaneously, therefore can adopts low-power machine, low load leading screw, can reduce cost greatly, simplify the structure.
Description of drawings
Fig. 1 is the structure cutaway view of this practical injection member.
The specific embodiment
With reference to the accompanying drawings this practical embodiment is described.
Leading screw 1, leading screw 2 through each its being installed in of bearing holder (housing, cover) 3 symmetries penetrate plate 15 left and right sides behind the platform; One end of leading screw 1 is fixedly synchronous pulley 4, synchronous pulley 7 respectively; One end of leading screw 2 is fixedly synchronous pulley 5, synchronous pulley 8 respectively; Wherein the synchronous pulley 4 on leading screw 1 synchronous pulley 5 and the leading screw 2 is through being with 6 to be connected, to reach synchronous operated purpose between leading screw 1, the leading screw 2 synchronously.On the leading screw 1 another one synchronous pulley 8 through synchronously with 9 with motor 13 on synchronous pulley 11 be connected.Another one synchronous pulley 7 on the leading screw 2 through synchronously with 10 with motor 14 on synchronous pulley 12 be connected, by motor 13 and motor 14 driving force is provided simultaneously.
All the other mechanisms are all similar with present monofilament thick stick driving mechanism, discuss no longer in detail at this.
