Description

A kind of injection mold with side core-pulling
Technical field
The utility model relates to the technical field of injection mold, especially a kind of injection mold with side core-pulling.
Background technology
Injection mold is the instrument producing plasthetics, and the material melted that is heated is injected die cavity by high pressure by it, after cooling curing, obtains formed products.Because the structure of existing most plastic products is very complicated, many times can with the hole of various sizes size in plastic products, this some holes is self-assembling formation in plastic product forming process, the shaping usual needs of this some holes are by side core, and the Core-pulling force of side core is comparatively large, at present the main mode of loosing core adopting spring, but because of the less stable of spring pulled core structure, therefore the whole process unreliable of loosing core, easily there is fault of loosing core, have influence on the normal injection moulding work of injection mold.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of injection mold with side core-pulling, overcomes existing injection mold side core and to loose core the defect of process instability.
The utility model solves the technical scheme that its technical problem adopts: a kind of injection mold with side core-pulling, has the solid plate, backing plate, concave template, push piece plate, moving platen and the core fixing plate that set gradually from top to bottom; The center position of described solid plate is provided with nozzle insert, the middle position of described core fixing plate upper surface is fixed with core, the left end of solid plate is provided with briquetting, the left end of backing plate and concave template is elasticly connected with swing hook jointly, the left end of described push piece plate is provided with block, the right-hand member of described concave template is provided with the side core slide block matched with the side opening of plastic products, and the right-hand member of solid plate is provided with can Angle Pin in the core slide block of inserting side and can clamp the wedge block of side core slide block.
Further, during injection mold die sinking described in technique scheme, swing hook hooks the block on moving platen, die joint between solid plate and backing plate is opened, side core slide block drives side core to extract out from plastic products, and the inclined-plane on briquetting drives swing hook to swing, and makes swing hook throw off block.
Further, what in technique scheme, common elasticity was connected to that described backing plate and the swing hook of concave template one end adopt is that spring is connected.
The beneficial effects of the utility model are: a kind of injection mold with side core-pulling of the present utility model, by installing swing hook, spring and briquetting respectively on mould, three forms mechanical swinging hook type parting tension mechanism, ensure that side core is loosed core more reliable and more stable in process, substantially increase quality and the accuracy of plastic products.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, solid plate, 2, backing plate, 3, concave template, 4, push piece plate, 5, moving platen, 6, core fixing plate, 7, nozzle insert, 8, core, 9, briquetting, 10, swing hook, 11, block, 12, plastic products, 13, side core slide block, 14, Angle Pin, 15, wedge block, 16, spring.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of injection mold with side core-pulling of the utility model as shown in Figure 1, has the solid plate 1, backing plate 2, concave template 3, push piece plate 4, moving platen 5 and the core fixing plate 6 that set gradually from top to bottom; The center position of solid plate 1 is provided with nozzle insert 7, the middle position of core fixing plate 6 upper surface is fixed with core 8, one end of solid plate 1 is provided with briquetting 9, one end of backing plate 2 and concave template 3 is elasticly connected with swing hook 10 jointly, one end of push piece plate 4 is provided with block 11, the other end of concave template 3 is provided with the side core slide block 13 matched with the side opening of plastic products 12, and the other end of solid plate 1 is provided with can Angle Pin 14 in inserting side core slide block 13 and can clamp the wedge block 15 of side core slide block 13.Wherein, what common elasticity was connected to that described backing plate 2 and the swing hook 10 of concave template 3 one end adopt is that spring 16 is connected.
Swing hook 10 on this injection mold, spring 16 and briquetting 9 three form mechanical swinging hook type parting tension mechanism, during injection mold die sinking, swing hook 10 hooks the block 11 on moving platen 5, die joint between solid plate 1 and backing plate 2 is opened, side core slide block 13 drives side core to extract out from plastic products 12, inclined-plane on briquetting 9 drives swing hook 10 to swing, and makes swing hook 10 throw off block 11; When dynamic model moves to certain position, the die joint between concave template 3 and push piece plate 4 is opened, and plastic products 12 take die cavity out of by core 8, and the die joint then between push piece plate 4 and moving platen 5 is opened, and releases plastic products 12 by push piece plate 1.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
