Abstract
The utility model discloses a threaded nut module adjusting device of an injection machine, which comprises a pull rod (2), a threaded module adjusting nut (3), and a threaded nut pressure plate (7), wherein the pull rod is mounted in a hole formed on one side of a tail plate (1), the pull rod and the hole are in clearance fit, a wear-resistant ring (5) is mounted in a hole formed on the other side of the tail plate, the external diameter of the wear-resistant ring and the tail plate are in clearance fit, the threaded module adjusting nut is mounted on the pull rod, the external diameter of the threaded module adjusting nut and an inner hole of the wear-resistant ring are in clearance fit, the threaded nut pressure plate is fixed on the tail plate on the side where the threaded module adjusting nut is mounted, and a drive element (9) is arranged on the threaded module adjusting nut. In the device, the threaded module adjusting nut is mounted inside the tail plate, and the contact among the threads of the pull rod and those of the threaded module adjusting nut is eliminated through the contact positioning of the wear-resistant ring and the threaded module adjusting nut, so as to reduce the resistance when in module adjusting and avoid damaging the threads.
Description
Technical field
The utility model relates to a kind of parts of injection machine, especially relates to a kind of injection machine screw mode transfer device.
Background technology
In injection machine, usually use screw mode transfer device to regulate the distance of template, screw mode transfer device is rotated by the mode transfer screw that hydraulic motor drives in the device, and the mode transfer screw reaches the purpose of regulating the template distance in the axial drive tailgate move left and right of the screw thread upper edge of pull bar pull bar.For most injection machine, tradition screw mode transfer Design of device scheme as shown in Figure 2, pull bar 2 is arranged in the hole of tailgate 1 both sides, mode transfer screw 3 is installed on the pull bar 2, at tailgate 1 left side Fixed Nut pressing plate 7, because pull bar 2 is fixed the gear ring on hydraulic motor drive mode transfer screw 3, mode transfer screw 3 axially moves along pull bar 2, drives tailgate 1 and moves to left or move to right.Though this structure can realize regulating the purpose of template distance, but at injection machine particularly in the large size plastic jetting-moulding device, the weight of mode transfer screw is heavier, because the mode transfer screw is suspended on the outside of tailgate, the last screw thread of mode transfer screw and pull bar contacts fully, resistance during destruction screw thread, and mode transfer easily is bigger, mode transfer may occur and transfer motionless situation.
The utility model content
The utility model mainly is to solve existing in prior technology mode transfer screw to expose on the pull bar that is suspended on outside the tailgate, easily cause thread damage, problem that the mode transfer resistance is bigger, a kind of injection machine screw mode transfer device is provided, this device is arranged on tailgate inside with the mode transfer screw, by the location that contacts of wear ring and mode transfer screw, eliminated the contacting of screw thread of pull rod screw and mode transfer screw.
Injection machine screw mode transfer device of the present utility model, be achieved by following technical proposals, the utility model comprises pull bar, mode transfer screw, screw pressing plate, pull bar is installed in the hole of tailgate one side, be matched in clearance between described pull bar and this hole, in another side opening of tailgate, wear ring is installed, the external diameter of this wear ring and tailgate matched in clearance, the mode transfer screw is installed on the pull bar, the endoporus matched in clearance of the external diameter of this mode transfer screw and wear ring, described screw pressing plate is fixed on the side that the mode transfer screw is installed on the tailgate, on described mode transfer screw driving element is set.So just, the mode transfer screw is built in the tailgate, utilizes wear ring location and support the mode transfer screw, make stressed reducing on the pull bar, the screw thread on not fragile mode transfer screw and the pull bar.
As preferably, described driving element is the mode transfer gear ring.The use gear ring drives, and transmission is stable.
As preferably, on wear ring and mode transfer screw contact-making surface, oil groove is set, the frictional force in the time of can reducing the rotation of mode transfer screw like this.
As preferably, described mode transfer screw is provided with step, makes things convenient for the installation and the location of mode transfer screw like this.
The beneficial effect of the utility model injection machine screw mode transfer device: this device is installed in tailgate inside with the mode transfer screw, the location that contacts by wear ring and mode transfer screw, eliminated contacting of pull rod screw and mode transfer screw screw thread, the resistance when having reduced mode transfer like this is difficult for damaged screw.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of existing injection machine screw mode transfer device.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, pull bar 2 is installed in the locating hole on tailgate 1 right side, tailgate 1 can be done axially-movable along pull bar 2, with cylindrical pin with external thread 4 wear ring 5 is installed on the step in tailgates 1 left hole, the external diameter of wear ring 5 and tailgate 1 matched in clearance, mode transfer screw 3 is screwed in the pull bar 2, step on the mode transfer screw 3 is contacted with 5 of wear rings, the internal orifice dimension matched in clearance of the external diameter of mode transfer screw 3 and wear ring 5, on the contact-making surface of wear ring 5 and mode transfer screw 3, drive oil groove, can reduce and mode transfer screw 3 between frictional force.At tailgate 1 left-external side bolt a6 Fixed Nut pressing plate 7, with bolt b8 mode transfer gear ring 9 is installed in mode transfer screw 3 left sides, is rotated when hydraulic motor drives mode transfer gear ring 9, mode transfer screw 3 is along pull bar 2 axially-movables, tailgate 1 reaches the purpose of regulating the template distance also thereupon along pull bar 2 axially-movables.
Claims (4)
1. injection machine screw mode transfer device, comprise pull bar (2), mode transfer screw (3), screw pressing plate (7), it is characterized in that: described pull bar (2) is installed in the hole of tailgate (1) one side, be matched in clearance between described pull bar (2) and this hole, wear ring (5) is installed in another side opening of described tailgate (1), the external diameter of this wear ring (5) and this tailgate (1) matched in clearance, described mode transfer screw (3) is installed on the pull bar (2), the endoporus matched in clearance of the external diameter of this mode transfer screw (3) and wear ring (5), described screw pressing plate (7) is fixed on described tailgate (1) and goes up the side that mode transfer screw (3) is installed, and driving element (9) is set on described mode transfer screw (3).
