The invention relates to a spray head, and in particular relates to a spray head of an injection molding machine. The spray head comprises a spray hole, a spray channel connected with the spray hole, and a feeding channel connected with the spray channel, wherein the feeding channel is provided with a main valve; the feeding channel between the spray channel and the main valve is connected with a material extraction channel; the material extraction channel is connected with a storage tank; a heating device is arranged in the storage tank; a guide pipe is connected between the material extraction channel and the feeding channel arranged between the spray channel and the main valve; the guide pipe is connected with an air pump; the two ends, connected with the air pump, of the guide pipe are respectively provided with a first valve and a second valve; the first valve is used for controlling the opening and closing between the guide pipe and the material extraction channel; and the second valve is used for controlling the opening and closing between the guide pipe and the feeding channel. After the spray head is used, the raw material left in the feeding channel can be adsorbed out after a device stops spraying the raw material, so that the raw material is prevented from overflowing from the spray hole; and if necessary, the raw material collected by adsorption can be adsorbed into the feeding channel again and is injected into a mould, so that the raw material can be recycled.
Description
Technical field
The present invention relates to a kind of shower nozzle, particularly relate to a kind of shower nozzle of injection machine.
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 sprayer of injection molding machine, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of sprayer of injection molding machine, can after equipment stops spraying raw material, the raw material be trapped in feeding channel is adsorbed, overflow from spray-hole to prevent raw material, also collected raw material after absorption again can be adsorbed to feeding channel and be expelled in mould if needed, realize the recycling of raw material.
A kind of sprayer of injection molding machine that the present invention proposes, comprise spray-hole, be connected with described spray-hole injection channel, the feeding channel be connected with described injection channel, described feeding channel is provided with main valve, feeding channel between described injection channel with described main valve expects that passage is connected with taking out, described material passage of taking out is connected with storage tank, heater is provided with in described storage tank, feeding channel between described injection channel and described main valve and described taking out expect to be connected with conduit between passage, described conduit is connected with air pump, the two ends of the connection air pump of described conduit are respectively equipped with the first valve and the second valve, conduit described in described first Valve controlling and take out the folding of expecting between passage, folding described in described second Valve controlling between conduit and feeding channel.
Further, described main valve is magnetic valve.
Further, described first valve and the second valve are stop valve.
Further, two ports of described conduit are provided with the first choker bar and the second choker bar.
Further, pressure sensor is provided with in described storage tank.
Further, the opening part of described spray-hole is provided with spreader.
By such scheme, the present invention at least has the following advantages: after equipment stops spraying raw material, main valve is closed, now open the first valve, feeding channel, take out material passage, storage tank and be communicated with conduit, after the gas taken out in material passage is evacuated to negative pressure by air pump, the raw material be trapped in feeding channel adsorbed and be stored in storage tank, overflowing from spray-hole to prevent raw material.If needed also by raw material collected after storage tank heating adsorption, then the second valve is opened when closing main valve and the first valve, now conduit, feeding channel, take out material passage be communicated with storage tank, after gas in feeding channel is evacuated to negative pressure by air pump, raw material in storage tank be adsorbed to feeding channel again and be expelled in mould, realizing the recycling of raw material.This apparatus structure is simple and economical and practical, and the fused raw material that effectively prevent delay overflows spray-hole, improves operating efficiency and has saved production cost.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, 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 invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
