Abstract
The utility model relates to a valve-type sprueless nozzle of an injection moulding machine. The front end face of a nozzle head is directly flush with the end face of the moulding cavity of a mould, so a sprueless nozzle is formed, and the outlet of the sprueless nozzle head is a tapered hole, the head part of a valve core is a relatively tapered head, and the tapered hole and the tapered head are fitted with each other and are in normally-closed state; so the utility model is formed. While in use, the wire drawing defect which is generated at a sprue can be conquered, and the utilization rate of the raw materials can reach to 100%. The utility model has the advantages of simple structure, safe work, high automation, low labour intensity and low cost. The valve-type sprueless nozzle of an injection moulding machine is suitable for the manufacture process of the part of the high molding precision.
Description
The utility model relates to the runner less nozzle of a kind of nozzle of injection machine, particularly a kind of injection machine.
At present, the injection machine runner less nozzle of extensive use both at home and abroad has the nozzle of prolongation and well formula nozzle, the nozzle that prolongs nozzle and be injection machine directly extends to mold cavity, carries out injection mo(u)lding, and well formula nozzle is to install a bullet passage between injection machine nozzle and mold cavity additional.These two kinds of nozzle temperatures are difficult to control, and they are not suitable for the high part of compact dimensions required precision, and the lower plastics of moulding melt viscosity easily produce the wire drawing phenomenon at the cast gate place, make that the product surface of injection mo(u)lding is coarse, need to increase the operation of modifying processing.Thereby product cost is improved, and labour intensity strengthens.
The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and a kind of injection machine valve-type runner less nozzle is provided.
Structure of the present utility model as shown in the figure.
Fig. 1 is a structural representation of the present utility model.
Such as Fig. 1, the utility model includes nozzle body 5, connection seat 7, be set with spring 6 and back-up ring 3 on the nozzle body 5, spacer pin 4 is equipped with in the spool bore rear end of nozzle body 5, spool 1 is housed in this spool bore, the front end of nozzle body 5 is connected with nozzle head 2, be set with heating collar 8 on the nozzle head 2, and nozzle head 2 front ends and stationary mould for mould plate 9 match, the front end face that is characterized in nozzle head 2 is directly concordant with the end face of mold cavity 10, consist of the runner less nozzle, and the outlet of nozzle head 2 is bellmouth, the head of spool 1 is corresponding Conical head, they match and are normally off, consist of the valve-type nozzle. Outlet the best of nozzle head 2 is conical bore, and correspondingly the head of spool 1 the best is nose cone, and they coincide and are integrated.
During the utility model work, the high-pressure smelting plastic warp connection seat 7 in the injecting machine material tube enters nozzle head 2 from the two side holes of nozzle body 5. Under normal conditions, because spring 6 makes spool 1 be closure state with nozzle head 2 all the time by the effect of back-up ring 3 and spacer pin 4, and when injection, the high-pressure smelting plastics force spool 1 to retreat, and by spacer pin 4 and back-up ring 3 Compress Springs 6, open cast gate, the high-pressure smelting plastics just directly inject mold cavity 10 by the bellmouth of nozzle head 2. After injection pressure is eliminated, the elastic restoring force of spool 1 dependence spring 6 is the bellmouth of valve nozzles head 2 again, cast gate is closed, because the front end face of nozzle head 2 is concordant with the end face of mold cavity 10, be the runner less nozzle, so the product surface of injection mo(u)lding is smooth, substantially do not stay gate vestiges, need not to modify again processing.
The utility model makes the cast gate place not have the wire drawing phenomenon and takes place that so no any runner scrap loss, stock utilization is 100% owing to adopt valve-type runner less nozzle.The utility model can be controlled the feed supplement time exactly, under HTHP, seal cast gate as soon as possible fast, prevented the refluence of molten plastic in the die cavity effectively, thereby reduced cast gate place puncture, reduce the internal stress of plastic products, reduced stress cracking and buckling deformation, improved the dimensional stability and the presentation quality of plastic products, reduce percent defective, be suitable for the high part of machine-shaping required precision.The utility model adopts the moulding of valve-type runner less nozzle, thus there is not the cast gate problem of solidification, thus make molding cycle shorten 15-20%, improved production efficiency.The utility model is simple in structure, and is safe and reliable, and the automaticity height has reduced operational sequence, has saved the energy, has saved materials, has alleviated working strength of workers, improved the service life of mould, reduced product cost.
Claims (2)
1, a kind of injection machine valve-type runner less nozzle, it includes nozzle body 5, connection seat 7, be set with spring 6 and back-up ring 3 on the nozzle body 5, spacer pin 4 is equipped with in the spool bore rear end of nozzle body 5, spool 1 is housed in this spool bore, the front end of nozzle body 5 is connected with nozzle head 2, be set with heating collar 8 on the nozzle head 2, and the front end of nozzle head 2 and mould solid plate 9 match, and it is characterized in that the front end face of nozzle head 2 is directly concordant with the end face of mold cavity 10, constitute the runner less nozzle, and the outlet of nozzle head 2 is a bellmouth, the head of spool 1 is corresponding conical head, and they match and are normally off, constitutes the valve-type nozzle.
2, by the described injection machine valve-type of claim 1 runner less nozzle, it is characterized in that outlet the best of nozzle head 2 is conical bore, correspondingly the head of spool 1 the best is a nose cone, they coincide and are one.
