Abstract
The utility model relates to an injection mold's technical field, especially, produce injection mold of large -scale thin -gage goods, through set up stop screw between cover half bedplate and fixed die plate, and suit disc spring on stop screw, during the die sinking, disc spring's elasticity makes fixed die plate and cover half bedplate part, it is separately apart from being controlled by stop screw, and then avoid large -scale thin -gage goods memory in the internal stress, avoid large -scale thin -gage goods to take place warpage, or even ruptured phenomenon, the qualities of large -scale thin -gage goods are greatly improved. This injection mold can avoid large -scale thin -gage goods memory in the internal stress, avoids large -scale thin -gage goods to take place warpage, ruptured phenomenon even, has improved the quality of large -scale thin -gage goods greatly.
Description
Technical field
The utility model relates to the technical field of injection mold, especially a kind of injection mold producing large thin-wall goods.
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.Large thin-wall goods occupy very large ratio in injection mold is produced, but there will be fiber-wall-element model in thermosetting plastics injection molding process, make to there is internal stress in large thin-wall goods, cause the buckling deformation of large thin-wall goods, even break.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of injection mold producing large thin-wall goods, overcomes the defect that existing injection mold occurs buckling deformation when producing large thin-wall goods, even breaks.
The utility model solves the technical scheme that its technical problem adopts: a kind of injection mold producing large thin-wall goods, there is the top clamping plate, solid plate, moving platen and the Bottom clamp plate that set gradually from left to right, the middle position of described top clamping plate is provided with locating ring, the inside of described locating ring is provided with nozzle insert and nozzle, be provided with stop screw between top clamping plate and solid plate, described stop screw is set with butterfly spring.
Further, in the top clamping plate described in technique scheme, be provided with the oblique heating tube near nozzle insert, can heat indirectly to the nozzle in nozzle insert like this, with the state making the melt in nozzle keep melting.
Further, the nozzle insert described in technique scheme be circumferentially provided with heater, can heat directly to the nozzle in nozzle insert like this, with the state making melt in nozzle keep melting.
Further, the cast gate formed during nozzle casting large thin-gage goods described in technique scheme is positioned at the middle position of large thin-wall goods, because melt is continuously from nozzle flow to cast gate, the melt at cast gate position continues the heating of the melt being subject to passing through, make the melt being positioned at centre remain molten condition, and then allow the melt from barrel continue through and to enter die cavity.
The beneficial effects of the utility model are: a kind of injection mold producing large thin-wall goods of the present utility model, by arranging stop screw between top clamping plate and solid plate, and on stop screw, be set with butterfly spring, during die sinking, the elastic force of butterfly spring makes solid plate separate with top clamping plate, its distance of separation is controlled by stop screw, and then avoid there is internal stress in large thin-wall goods, the phenomenon of avoid large thin-wall goods generation buckling deformation, even breaking, substantially increases the quality of large thin-wall goods.
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, top clamping plate, 2, solid plate, 3, moving platen, 4, Bottom clamp plate, 5, locating ring, 6, nozzle insert, 7, nozzle, 8, stop screw, 9, butterfly spring, 10, oblique heating tube, 11, heater, 12, large thin-wall goods, 13, cast gate.
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 producing large thin-wall goods of the utility model as shown in Figure 1, there is the top clamping plate 1, solid plate 2, moving platen 3 and the Bottom clamp plate 4 that set gradually from left to right, the middle position of top clamping plate 1 is provided with locating ring 5, the inside of locating ring 5 is provided with nozzle insert 6 and nozzle 7, be provided with stop screw 8 between top clamping plate 1 and solid plate 2, stop screw 8 be set with butterfly spring 9.
Be provided with the oblique heating tube 10 near nozzle insert 6 in top clamping plate 1, oblique like this heating tube 10 can heat indirectly to the nozzle 7 in nozzle insert 6, with the state making the melt in nozzle 7 keep melting.Nozzle insert 6 be circumferentially provided with heater 11, such heater 11 can heat directly to the nozzle 7 in nozzle insert 6, with the state making melt in nozzle 7 keep melting.The cast gate 13 formed during nozzle 7 casting large thin-gage goods 12 is positioned at the middle position of large thin-wall goods 12, because melt is continuously from nozzle flow to cast gate 13, the melt at cast gate 13 position continues the heating of the melt being subject to passing through, make the melt being positioned at centre remain molten condition, and then allow the melt from barrel continue through and to enter die cavity.
This injection mold, by arranging stop screw 8 between top clamping plate 1 and solid plate 2, and on stop screw 8, be set with butterfly spring 9, during die sinking, the elastic force of butterfly spring 9 makes solid plate 2 separate with top clamping plate 1, and its distance of separation is controlled by stop screw 8, and then avoids there is internal stress in large thin-wall goods 12, the phenomenon avoiding large thin-wall goods 12 buckling deformation to occur, even breaks, substantially increases the quality of large thin-wall goods 12.
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.
