Abstract
The invention provides a mold adjusting anti-loose device for an injection molding machine. In the device, a mounting support is arranged on a rear template which is provided with a mold adjusting gear set of the injection molding machine; a through hole is formed in the mounting support; an ejector rod is arranged in the through hole; one end of the ejector rod is pressed into a tooth groove on a mold adjusting nut, and the other end of the ejector rod passes through the through hole and a spring to be connected with a connecting pin; the connecting pin is connected with a supporting rod; the supporting rod is connected with a handle; and the connecting pin, the supporting rod and the handle form a connecting rod structure. The device has a simple structure; and the mold adjusting nut is fixed through the ejector rod, so that a mold adjusting structure is effectively prevented from loosing, and the device is relatively convenient to use.
Description
Technical field
The present invention relates to the injection machine field, especially relate to the locking unloading device of injection machine mode transfer structure.
Background technology
At present, in the injection machine use, because the template poor rigidity, reason such as four pull bar unbalance stress, pull bar and mode transfer nut connecting thread gaps are big causes injection machine in use for some time, the phenomenon that mode transfer structure pine moves back occurs, make that the mould lock is not tight, cause the injection moulding substandard products.The prior art injection machine does not prevent the device that mode transfer structure pine moves back mostly, and the part injection machine has the method for taking the hydraulic pressure briquetting to push down the mode transfer gear wheel, but its complex structure, cost is higher.
Summary of the invention
The present invention lacks the device that prevents that mode transfer structure pine from moving back for solving the prior art injection machine, or locking unloading device complex structure, cost technical problems of high, provide a kind of injection machine mode transfer locking unloading device, this apparatus structure is simple, easy for installation, use reliably, can prevent effectively that the pine of injection machine mode transfer structure from moving back.
In order to achieve the above object, the technical solution adopted in the present invention is: provide a kind of injection machine mode transfer structure locking unloading device, it comprises rear pattern plate, mode transfer gear wheel, mode transfer nut, pull bar; Described mode transfer gear wheel and pull bar are fixed on the rear pattern plate, and described mode transfer nut is fixed on the pull bar, and described mode transfer nut is by teeth groove and the engagement of mode transfer gear wheel; Side at described rear pattern plate is provided with erection support, and described erection support is provided with through hole, is provided with push rod in the described through hole; One end of described push rod is connected with connecting pin; Be provided with spring between described connecting pin and erection support, described push rod passes through hole on spring and the described erection support and heads in the teeth groove on the mode transfer nut; Described connecting pin is connected with pole, and described pole is connected with handle; Described handle is fixed on the erection support by fixed axis, and described handle can rotate around described fixed axis; Described connecting pin, pole and handle form bar linkage structure.
Further, the flank of tooth contact jaw of described push rod and mode transfer nut is the tooth form structure.
In the course of work, when injection machine needed normal mode transfer, by jack-up, the push rod head left the teeth groove of mode transfer nut under the effect of spring for pull-up handle, push rod; Regulate the mode transfer nut and carry out normal mode transfer work.After mode transfer finishes, depress handle, the tooth form head of push rod just in time inserts in the teeth groove on the mode transfer nut; Because the connecting rod effect of handle, pole and connecting pin, turn over the latching point of pole when handle after, push rod is pressed to the erection support side by pole with handle under the effect of spring, handle can not be lifted; With regard to locked mode transfer nut, prevented the loosening of template like this.
The present invention compares with prior art, and its effect is significantly significantly.The present invention adds linkage on existing injection machine rear pattern plate, depress handle and get final product mechanical locked mode transfer nut, lifts handle and can carry out normal mode transfer work; Whole apparatus structure is simple, and is easy to use, can prevent effectively that the pine of injection machine mode transfer structure from moving back.

The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
Injection machine mould adjusting mechanism as shown in Figure 3 comprises mode transfer gear wheel 11, mode transfer nut 12, pull bar 13; Mode transfer gear wheel 11 and pull bar 13 are fixed on the rear pattern plate 14, and mode transfer nut 12 is fixed on the pull bar 13, and mode transfer nut 12 is by teeth groove and 11 engagements of mode transfer gear wheel.Realize the work of injection machine mode transfer by adjusting mode transfer nut 12.
As Fig. 1, Fig. 3 and shown in Figure 4, rear pattern plate 14 is provided with erection support 1, has through hole on the erection support 1, passes through hole and is provided with push rod 2, and an end of push rod 2 is connected with connecting pin 3.Be provided with spring 5 between connecting pin 3 and the erection support 1, push rod 2 passes through hole on spring 5 and the erection support 1 and heads in the teeth groove on the mode transfer nut 12.Connecting pin 3 connects pole 4, and pole 4 is connected with handle 6; Handle 6 is fixed on the erection support 1 by fixed axis 7, and handle 6 can rotate around fixed axis 7.Handle 6, pole 4 and connecting pin 3 form bar linkage structure.
As shown in Figure 2, in the course of work, pull-up handle 6, by jack-up, the head of push rod 2 leaves the teeth groove on the mode transfer nut 12 to push rod 2 under the effect of spring 5 and pole 4, adjusts mode transfer nut 12 and realizes normal mode transfer work.
As Fig. 1 and shown in Figure 5, after the mode transfer process finishes, depress handle 6, because the bar linkage structure of handle 6, pole 4 and connecting pin 3, turn over the latching point of pole 4 when handle 6 after, by the effect of spring 5, pole 4 is pressed to the side of erection support 1 with handle 6 and is fixed, also push rod 2 is depressed simultaneously, the tooth form head of push rod 2 is inserted in the teeth groove of mode transfer nut 12, effectively prevented the loosening of mode transfer nut.
