Detailed Description
The utility model is further described below with reference to the accompanying drawings:
referring to fig. 1 and 2, an electric driving device includes a guiding mechanism, a hollow support 2, a motor 3, a ball screw 4 and a lifting seat 5, wherein the guiding mechanism and the motor 3 are both mounted on the hollow support 2, an output end of the motor 3 faces downward and is in driving connection with a screw portion of the ball screw 4, a nut portion of the ball screw 4 is mounted on the lifting seat 5, the lifting seat 5 is in slidable connection with the guiding mechanism, and the motor 3 drives the ball screw 4 to drive the lifting seat 5 to move up and down; the guide mechanism comprises guide post modules 11 which are symmetrically arranged, each guide post module 11 comprises a hollow guide post 111, an upper limiting ring 112 and a lower limiting ring 113, the upper limiting ring 112 and the lower limiting ring 113 are both sleeved on the hollow guide post 111, the left end and the right end of the lifting seat 5 are respectively provided with a sleeve structure, and the sleeve structures are sleeved on the hollow guide post 111 and are located between the upper limiting ring 112 and the lower limiting ring 113.
Referring to fig. 1 and 2, the device further comprises a hanging ring 6, and the hanging ring 6 is symmetrically arranged on the hollow support 2. The hoisting equipment drives the hoisting ring 6 to realize the lifting of the hoisting equipment, so that the hoisting equipment is convenient to hoist.
Referring to fig. 1 and fig. 3, the first embodiment is different from the second embodiment in that: the pressure sensing mechanism 7 is arranged on the lifting seat 5, the pressure sensing mechanism 7 comprises a flange type pressure sensor 71 and a flange type pressure transmission rod 72, the flange type pressure sensor 71 is arranged on the lifting mechanism, and the flange type pressure transmission rod 72 is arranged on the flange type pressure sensor 71.
The working principle of the utility model is as follows:
the amount of molten plastic entering the glue injection device is increased, the internal volume of the glue injection device is increased, the glue injection device moves upwards to drive the flange type pressure transmission rod 72 to apply pressure to the flange type pressure sensor 71, when the pressure value detected by the flange type pressure sensor 71 reaches the set pressure value, the amount of the molten plastic entering the glue injection device is enough, at the moment, the motor 3 drives the ball screw 4 to press the glue injection device through the flange type pressure sensor 71 and the flange type pressure transmission rod 72 of the lifting seat 5 successively, and the glue injection device completes glue injection work on a mold;
when the volume of the product is changed, the motor 3 can conveniently drive the ball screw 4 to drive the lifting seat 5 to move up and down, so that the automatic adjustment of the movement stroke is realized, and the product with different volumes can be conveniently adapted;
the self weight can be reduced by arranging the hollow guide column 111, the light weight is realized, the upper limit position and the lower limit position of the sleeve structure are limited by arranging the upper limit ring 112 and the lower limit ring 113, and the situation that the nut part is driven by the motor 3 to move upwards to cause the nut part to collide with the lifting seat 5 or the nut part is driven by the motor 3 to move downwards to cause the nut part to separate from the screw rod when the equipment debugging process or the system fails is prevented.
The technical scope of the present invention is not limited to the above embodiments, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.
