Abstract
The invention relates to the technical field of injection dies, particularly to a single-mold-cavity injection die. The single-mold-cavity injection die comprises a fixed clamping plate, wherein a locating ring is arranged at the middle of the left end face of the fixed clamping plate; a cup-shaped main runner is arranged at the right end of the locating ring; a stripper plate, a movable die plate and a mold core fixing plate are sequentially arranged on the right end face of the fixed clamping plate from left to right; a mold core is fixedly mounted at the middle of the left end face of the mold core fixing plate; a nozzle is arranged at the middles of the locating ring and the cup-shaped main runner jointly; the left end part of the nozzle stretches out of the external part of the left end face of the fixed clamping plate. The single-mold-cavity injection die enables melt in the cup-shaped main runner to be kept in the molten state to effectively prevent melt in the cup-shaped main runner from solidification, so that cost for adopting manpower and material resources to dredge the cup-shaped main runner is reduced, and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to the technical field of injection mold, especially a kind of single-cavity injection mold.
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.But, existing most injection mold comes with some shortcomings part in structural design, as: there is the phenomenon of solidifying in the melt in sprue, causes injection moulding work to go on often, the dredging work of sprue is also very difficult simultaneously, wastes very large manpower and materials.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of single-cavity injection mold, overcome the defect that sprue melt solidifying easily appears in existing injection mold.
The technical solution adopted for the present invention to solve the technical problems is: a kind of single-cavity injection mold, there is top clamping plate, locating ring is provided with in the middle part of the left side of described top clamping plate, the right-hand member of described locating ring is provided with cup type sprue, the right side of top clamping plate is disposed with stripper, moving platen and core fixing plate from left to right, a core is installed with in the middle part of the left side of described core fixing plate, the middle part of locating ring and cup type sprue is provided with nozzle jointly, and the left part of described nozzle stretches out in the outside of top clamping plate left side.
Further restriction, is located by connecting by spring between the cup type sprue described in technique scheme and top clamping plate, and the arranging of spring can facilitate carrying out smoothly of the die sinking action of injection mold and mould assembling action.
Further restriction, the import caliber size in the left side of the cup type sprue described in technique scheme is greater than the outlet caliber size on the right side of it so that melt more evenly consolidation enter into die cavity.
Further restriction, the cast gate formed when the nozzle described in technique scheme pours into a mould plastic products is positioned at the middle position of plastic products.
The invention has the beneficial effects as follows: single-cavity injection mold of the present invention, by the structure that the entrance point of nozzle is arranged to protrude from outside top clamping plate, the melt contributed in cup type sprue keeps the state of melting, namely the melt solidifying in cup type sprue is effectively avoided, decrease the cost that manpower and materials remove to dredge cup type sprue, substantially increase production efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1, top clamping plate, 2, locating ring, 3, cup type sprue, 4, stripper, 5, moving platen, 6, core fixing plate, 7, core, 8, nozzle, 9, spring, 10, cast gate, 11, plastic products.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Single-cavity injection mold of the present invention as shown in Figure 1, has top clamping plate 1, is provided with locating ring 2 in the middle part of the left side of top clamping plate 1, and the right-hand member of locating ring 2 is provided with cup type sprue 3, and what cup type sprue 3 adopted is heat-insulating hot channel, is applicable to single-cavity mould.The right side of top clamping plate 1 is disposed with stripper 4, moving platen 5 and core fixing plate 6 from left to right, a core 7 is installed with in the middle part of the left side of core fixing plate 6, the middle part of locating ring 2 and cup type sprue 3 is provided with nozzle 8 jointly, and the left part of nozzle 8 stretches out in the outside of top clamping plate 1 left side.Be located by connecting by spring 9 between cup type sprue 3 and top clamping plate 1, the arranging of spring 9 can facilitate carrying out smoothly of the die sinking action of injection mold and mould assembling action.The import caliber size in the left side of cup type sprue 3 is greater than the outlet caliber size on the right side of it so that melt more evenly consolidation enter into die cavity.The cast gate 10 that nozzle 8 is formed when pouring into a mould plastic products is positioned at the middle position of plastic products 11.Because the melt layer in cup type sprue 3 is thicker, and heated by nozzle 8 and the melt that passes through at every turn, so be positioned at centre to remain molten condition, allow the melt from barrel continue through and to enter die cavity, in order to continuously shaped, nozzle 8 and cup type sprue 3 close contact.
When mould die sinking, agent structure stripper 4 in mould, moving platen 5, core fixing plate 6 and the core 7 be fixed on core fixing plate 6 are all separated with cup type sprue 3 and nozzle 8, effectively can avoid the melt solidifying in cup type sprue 3, simultaneously, due to the entrance point of nozzle 8 is arranged to protrude from the structure outside top clamping plate 1, the melt contributed in cup type sprue 3 keeps the state of melting, namely the melt solidifying in cup type sprue 3 can also effectively be avoided, decrease the cost that manpower and materials remove to dredge cup type sprue 3, substantially increase production efficiency.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
