Abstract
The utility model discloses an injection mold capable of realizing linked thread disengagement. A moving mold plate is equipped with a threaded core, the threaded core comprises a threaded end part and a gear end part, the threaded core can be relatively rotationally mounted on a fixed support plate of the moving mold plate, the fixed support plate is provided with a driving gear, and the driving gear is in driving connection with the gear end part of the threaded core; a driving rack is mounted on a fixed mold plate and meshed with the driving gear. During mold opening, the moving mold plate moves relative to the fixed mold plate, at the moment, the driving rack mounted on the fixed mold plate moves relative to the moving mold plate, the driving gear moves to drive the driving gear to rotate, the rotating driving gear drives the threaded core to rotate, and the rotating threaded core finally disengages from a threaded structure of a plastic product. According to the injection mold, the thread disengagement action is completed in a linked manner, that is, the thread disengagement action and the mold opening action are performed simultaneously and synchronously, so that the injection mold has the advantages of simple structure, better stability and reliability and low production and machining cost.
Description
Technical field
The utility model relates to injection mold technical field, relates in particular to the injection mold of the de-screw thread of a kind of linkage.
Background technology
For the plasthetics that has helicitic texture for moulding, injection mold generally carrys out the helicitic texture of forming plastic product by corresponding thread core; For thread core is successfully thrown off with plasthetics, prior art generally adopts the structure of oil cylinder mate gear to drive thread core to rotate, just and can make thread core and plasthetics throw off under the condition of only rotating at thread core.Yet in actual process of manufacture, there is complex structure, cost is high and reliability is poor defect in above-mentioned de-thread mechanism.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art the injection mold of the de-screw thread of a kind of linkage, and the injection mold production and processing cost of the de-screw thread of this linkage is low and reliability is better, and overall structure is comparatively simple.
For achieving the above object, the utility model is achieved through the following technical solutions.
The injection mold of the de-screw thread of a kind of linkage, include moving platen and the solid plate of arranged stacked, moving platen is fitted with thread core group, thread core group includes thread core, thread core includes the geared end that is inserted into the thread head in shaping mold cavity and is positioned at the opposition side of thread head, the corresponding thread core of moving platen is equiped with fixed support plate, thread core is installed in fixed support plate rotatably, fixed support plate is equiped with driven wheel rotatably, and driven wheel drives and is connected with the geared end of thread core; Solid plate is equiped with the driving tooth bar extending along die sinking direction, drives tooth bar and driven wheel engagement.
Wherein, the corresponding described driving tooth bar of described solid plate is fitted with tooth bar fixed block, and tooth bar fixed block is screwed on solid plate, drives an end of tooth bar to be screwed on tooth bar fixed block.
The beneficial effects of the utility model are: the injection mold of the de-screw thread of a kind of linkage described in the utility model, its moving platen is fitted with thread core, thread core includes thread head and geared end, thread core is installed in the fixed support plate of moving platen rotatably, fixed support plate is equiped with driven wheel, and driven wheel drives and is connected with the geared end of thread core; Solid plate is equiped with driving tooth bar, drives tooth bar and driven wheel engagement.During die sinking, moving platen moves relative to solid plate, now, the driving tooth bar that is installed on solid plate moves relative to moving platen, driven wheel moves and drives driven wheel to rotate, and the driven wheel of rotation drives thread core to rotate again, and the thread core helicitic texture final and plasthetics of rotation is thrown off.The utility model completes de-action, thread by the form of interlock, and de-action, thread is synchronizeed and carried out with die sinking action simultaneously; So, the utlity model has simple in structure, reliability better and the low advantage of production and processing cost.
Accompanying drawing explanation
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing does not form any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.

The specific embodiment
Below in conjunction with concrete embodiment, the utility model is described.
As shown in Figure 1 to Figure 3, the injection mold of the de-screw thread of a kind of linkage, include moving platen 1 and the solid plate 2 of arranged stacked, moving platen 1 is fitted with thread core group 3, thread core group 3 includes thread core 31, thread core 31 includes the geared end 312 of the thread head 311 being inserted in shaping mold cavity and the opposition side that is positioned at thread head 311, the corresponding thread core 31 of moving platen 1 is equiped with fixed support plate 4, thread core 31 is installed in fixed support plate 4 rotatably, fixed support plate 4 is equiped with driven wheel 5 rotatably, driven wheel 5 drives and is connected with the geared end 312 of thread core 31, solid plate 2 is equiped with the driving tooth bar extending along die sinking direction, drives tooth bar and driven wheel 5 engagements.
Wherein, the corresponding tooth bar that drives of solid plate 2 is fitted with tooth bar fixed block 7, and tooth bar fixed block 7 is screwed on solid plate 2, drives an end of tooth bar to be screwed on tooth bar fixed block 7.
Need further to explain, thread core group 3 of the present utility model can have a thread core 31, also can have two or two thread cores that are arranged in parallel above 31; As shown in Figures 2 and 3, thread core group 3 of the present utility model has four thread cores that are arranged in parallel 31.
During die sinking, moving platen 1 moves relative to solid plate 2, now, the driving tooth bar that is installed on solid plate 2 moves relative to moving platen 1, driven wheel 5 moves and drives driven wheel 5 to rotate, the driven wheel 5 rotating drives thread core 31 to rotate again, and thread core 31 helicitic texture final and plasthetics of rotation is thrown off.
Comprehensive above-mentioned situation is known, and the utility model completes de-action, thread by the form of interlock, and de-action, thread is synchronizeed and carried out with die sinking action simultaneously; So, the utlity model has simple in structure, reliability better and the low advantage of production and processing cost.
