Description
Technical field
The utility model relates to a kind of nozzle, particularly relates to a kind of injection molding machine nozzle.
Background technology
Injection machine is that one utilizes mould for plastics, thermoplastic or heat fixing character plastics is made the main former of the plastic products of various shape.Need solid feed to melt during its work, then by feed pipe and nozzle injection to die for molding.In injection-moulding device conventional at present, generally upon completion of the injection, still can continue the raw material flowing out molten state in nozzle, particularly when material viscosity is lower, phenomenon is even more serious.If the raw material flowed out sticks on shaping product, product surface out-of-flatness can be caused, unsightly, easily obtain substandard products.
In order to address this problem; usually the cool time of injection mold can be extended, but greatly reduce operating efficiency like this, and the molten plastic at the spray-hole place being trapped in nozzle easily blocks spray-hole; blocking post processing is got up cumbersome, can affect normal production.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of injection molding machine nozzle, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of injection molding machine nozzle, after equipment stops spraying raw material, can be adsorbed by the raw material be trapped in feeding channel, overflow to prevent raw material from spray-hole.
A kind of injection molding machine nozzle that the utility model proposes, the feeding channel comprising spray-hole, the injection channel be connected with described spray-hole and be connected with described injection channel, described feeding channel is provided with main valve, feeding channel between described main valve with described injection channel expects that passage is connected with taking out, described material passage of taking out is connected with storage tank, described storage tank is connected with air pump, described in take out material passage be provided with auxiliary-valve.
Further, described main valve and described auxiliary-valve are magnetic valve.
Further, described main valve is connected by circuit with described auxiliary-valve, and described auxiliary-valve power-off during the energising of described main valve, described auxiliary-valve energising during described main valve power-off.
Further, pressure sensor is provided with in described storage tank.
Further, the opening part of described spray-hole is provided with spreader.
Further, described spreader adopts wear-resisting, resistant to elevated temperatures metal material to make.
By such scheme, the utility model at least has the following advantages: when the main valve on feeding channel is closed, stop mold ejector raw material, open the auxiliary-valve taken out on material passage, feeding channel, take out material passage to be communicated with storage tank, now, storage tank is evacuated to negative pressure by air pump, therefore the raw material be trapped in feeding channel is adsorbed in storage tank along taking out material passage, this device can effectively prevent spray-hole from overflowing the raw material of delay after equipment stops feeding, and the raw material collected in storage tank can be recycled, structure is simply easy to operation, and it is economical and practical.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1, a kind of injection molding machine nozzle of the utility model one preferred embodiment, the feeding channel 3 comprising spray-hole 1, the injection channel 2 be connected with spray-hole 1 and be connected with injection channel 2, feeding channel 3 is provided with main valve 4, feeding channel 3 between main valve 4 with injection channel 2 expects that passage 5 is connected with taking out, take out material passage 5 to be connected with storage tank 6, storage tank 6 is connected with air pump (not shown), takes out material passage 5 and is provided with auxiliary-valve 7.Main valve 4 and auxiliary-valve 7 are magnetic valve, and are connected by circuit, and auxiliary-valve 7 power-off when main valve 4 is energized, during main valve 4 power-off, auxiliary-valve 7 is energized.In storage tank 6, be provided with pressure sensor (not shown), be provided with spreader (not shown) at the opening part of spray-hole 1, this spreader adopts wear-resisting, resistant to elevated temperatures metal material to make.
When injection machine is to the plastics of mold injects molten state, main valve 4 is opened, auxiliary-valve 7 is closed automatically, when completing the operation of injection moulding, after being closed by main valve 4, auxiliary-valve 7 is opened automatically, now, feeding channel 3 with take out expect passage 5, storage tank 6 is communicated with, and is pumped into negative pressure state by air pump in storage tank 6, the raw material be therefore trapped in feeding channel 3 is adsorbed in storage tank 6 by along taking out material passage 5.In storage tank 6, be provided with pressure sensor, pressure in monitoring storage tank 6, control adsorption process and steadily carry out.
This device can effectively prevent spray-hole from overflowing raw material and the raw material blocking spray-hole of delay after equipment stops feeding, and the raw material collected in storage tank can be recycled, the structure of this device is simple, be easy to operation, and it is economical and practical, improve the operating efficiency of injection machine, save cost of material.
The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
