Abstract
The utility model discloses a monomer type jet nozzle with multiple injection moulding mouths, which comprises a heating and temperature-sensing coil wound on the outer wall of a jet nozzle body, wherein a feed inlet is formed at the top of the jet nozzle body; a plurality of mutually parallel jet nozzle cavities are formed in the centre of the jet nozzle body; the upper ends of the jet nozzle cavities are communicated with the feed inlet; a jet nozzle mouth is formed at the lower end of each jet nozzle cavity; the number of the jet nozzle mouths is 2 to 8; and the jet nozzle mouths are annularly and uniformly distributed with the axial line of the jet nozzle body as the centre. In the monomer type jet nozzle with multiple injection moulding mouths, because the jet nozzle cavities and the jet nozzle mouths corresponding to the jet nozzle cavities are formed in the jet nozzle body, injection moulding manufacture of a plurality of small products by one jet nozzle can be realized. When the jet nozzle is compared with a traditional jet nozzle, the production cost is greatly reduced, and the production efficiency is improved on the one hand; and mould cavities of a mould are more compactly arrayed, and the volume of the mould is reduced on the other hand.
Description
Technical field
The utility model relates to the nozzle in a kind of hot runner mould, relates to a kind of monomer-type nozzle that has a plurality of injection holes that is used for miscellaneous goods injection moulding manufacturing specifically.
Background technology
Compare with traditional cold runner mould; hot runner mould has advantages such as economizing in raw materials, enhances productivity and is widely adopted; nozzle is the critical piece in the hot runner mould; existing nozzle has a charging aperture and a discharging opening usually; charging aperture and discharging opening connect by the nozzle chambers at nozzle body center; for guaranteeing the flowability of injection molding material in nozzle, also must on the outer wall of nozzle body, winding heat the temperature-sensitive coil usually.Because existing nozzle has only a discharging opening, so sprue gate that nozzle can only a corresponding mould, when when the miscellaneous goods injection moulding is made, usually be provided with a plurality of die cavitys in one pair of mould, to realize the injection moulding manufacturing of mould fecund product, this moment, each die cavity all needed the corresponding nozzle that is provided with, cause the raising greatly of production cost, simultaneously, multiinjector makes that also the arrangement of die cavity can't be tight, makes the volume of mould bigger.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of monomer-type nozzle with a plurality of injection holes, and it can carry out the injection moulding of a plurality of abortion mouths simultaneously and make.
For achieving the above object, the technical solution adopted in the utility model is: a kind of monomer-type nozzle that has a plurality of injection holes, comprise the heating temperature-sensitive coil of winding on the nozzle body outer wall on the nozzle body, the top of described nozzle body has a charging aperture, the center of described nozzle body has several nozzle chambers that is arranged in parallel, the upper end and the charging aperture of described several nozzle chambers connect, and the lower end of described each nozzle chambers respectively is provided with a jet hole.
The number of described jet hole is 2-8, and described jet hole is that the center evenly distributes ringwise with the axis of nozzle body.
Adopted the monomer-type nozzle that has a plurality of injection holes of the present utility model, owing to have several nozzle chambers and the jet hole corresponding in its nozzle body with it, can realize the injection moulding making of single-nozzle to a plurality of miscellaneous goods, compare with traditional nozzle, reduce production cost greatly on the one hand, improved production efficiency, simultaneously, make that also the die cavity arrangement of mould is tightr, reduced the volume of mould.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the nozzle when adopting 2 jet holes is looked up structural representation.
Fig. 3 is that the nozzle when adopting 8 jet holes is looked up structural representation.
Among the figure: 1-nozzle body, 2-heating temperature-sensitive coil, 3-charging aperture, 4-nozzle chambers, 5-jet hole.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of monomer-type nozzle that has a plurality of injection holes, comprise the heating temperature-sensitive coil 2 of winding on nozzle body 1 outer wall on the nozzle body 1, the top of described nozzle body 1 has a charging aperture 3, in sum, with existing hot runner mould in monomer-type nozzle basically identical.
Innovative point of the present utility model is that mainly the center of described nozzle body 1 has several nozzle chambers that is arranged in parallel 4, and the upper end of described several nozzle chambers 4 and charging aperture 3 connect, and the lower end of described each nozzle chambers 4 respectively is provided with a jet hole 5.When carrying out injection moulding making miscellaneous goods, injection molding material carries out nozzle body 1 by charging aperture 3, and flow into respectively be arranged in parallel and each nozzle chambers 4 independently in, finally flow out injection moulding making when finally flowing into each die cavity in the mould and finish to a plurality of miscellaneous goods from each jet hole that is connected with nozzle chambers 45.
In actual applications, according to the size of the miscellaneous goods of making, the number of described jet hole 5 is 2-8, and described jet hole 5 is that the center evenly distributes ringwise with the axis of nozzle body 1.Specifically, when the miscellaneous goods of making is relatively large, can adopts less number jet hole 5 on the nozzle, as adopt 2 jet holes 5, simultaneously, the number of corresponding nozzle chambers 4 also should be 2; When the miscellaneous goods of making relatively hour, can adopt more number jet hole 5 on the nozzle, as adopt 8 jet holes 5, simultaneously, the number of corresponding nozzle chambers 4 also should be 8.Certainly jet hole 5 and nozzle chambers 4 can also adopt other number, as adopt 3,4,5,6 etc.
Claims (2)
1. the nozzle of injection hole monomer-type more than a kind, comprise the upward heating temperature-sensitive coil (2) of winding on nozzle body (1) outer wall of a nozzle body (1), the top of described nozzle body (1) has a charging aperture (3), the center that it is characterized in that described nozzle body (1) has several nozzle chambers that is arranged in parallel (4), upper end of described several nozzle chambers (4) and charging aperture (3) connect, and the lower end of described each nozzle chambers (4) respectively is provided with a jet hole (5).
2. many injection holes monomer-type nozzle according to claim 1, the number that it is characterized in that described jet hole (5) are 2-8, and described jet hole (5) is that the center evenly distributes ringwise with the axis of nozzle body (1).
