Description
Technical field
The utility model relates to a kind of hot runner mould, relate to specifically a kind of one go out many, the hot runner mould that side direction is entered to water.
Background technology
For ease of formed product, simplify mould structure, usually adopt 90 degree of side direction to enter the mode of watering to carry out cast product, be commonly called as side and enter to water.Existing side is entered to water hot runner mould and is generally included a mold, the center of described mold is provided with a vertical nozzle body with heater, several discharging openings are had in the bottom of nozzle body, described nozzle body discharging opening has been threaded a nozzle head respectively, and the spout of each nozzle head is connected with a die cavity respectively.Although adopt the side of this structure to enter to water hot runner mould can realize one and go out many objects, but owing to being anti-leak-stopping material, its nozzle body and nozzle head are threaded connection, cause the installation more complicated of mould, when nozzle head uses a period of time to change, first must pull down die cavity, then just nozzle head can be backed out, bother very much, and the nozzle head offside of die cavity, a skewback must be used to withstand the envelope material of guarantee die cavity, make mould need larger space, cause the number that of mould to tail off, reduce production efficiency.
Utility model content
For overcoming above-mentioned defect, it is less that the utility model aims to provide a kind of volume, and the easier side of dismounting is entered to water hot runner mould.
For achieving the above object, the technical solution adopted in the utility model is: a kind of side is entered to water hot runner mould, comprise a mold, the center of described mold is provided with a vertical nozzle body with heater, the bottom of described nozzle body has several discharging openings, usual described discharging opening is circularly and evenly distributed along the periphery of nozzle body, each discharging opening is connected with a nozzle head respectively, the spout of described each nozzle head is connected with a die cavity respectively, usually a groove matched with nozzle head dummy shape is provided with at the charging aperture place of die cavity, during assembling, nozzle head is put into this groove, make the spout of nozzle head aim at the charging aperture of die cavity simultaneously, the nozzle of described nozzle head is provided with an elastic washer, usually on nozzle head, be provided with a step, described elastic washer is just placed on this step, a heat insulating washer is provided with between described elastic washer and die cavity, the tail end of described nozzle head is connected with die cavity by a nut, namely nut is connected with groove, the discharge outlet of the bottom of described nozzle body is provided with an envelope top dressing matched with the tail end of nozzle head, after nozzle body and nozzle head are in place, discharging opening on nozzle body just aims at the charging aperture of nozzle head tail end, the bottom of described envelope top dressing is that an envelope tilted to nozzle body axle center waters inclined-plane.
Described die cavity is positioned at and is provided with an alignment pin with the relative position of nozzle head contact site.
Have employed side of the present utility model to enter to water hot runner mould, by arranging the envelope top dressing matched with the tail end of nozzle head at the tail end of nozzle body, by the elasticity of elastic washer, nozzle body is compressed mutually with nozzle head again, guarantee that injection molding material can not leak out from its composition surface, the installation of this mode can change nozzle head by extracting nozzle body out easily, avoids traditional side and enters to water hot runner mould and whole die cavity all need be removed when changing nozzle head.

In figure: 1-mold, 2-nozzle body, 3-discharging opening, 4-nozzle head, 5-die cavity, 6-elastic washer, 7-seals top dressing, and 8-envelope waters inclined-plane, 9-heat insulating washer, 10-alignment pin, 11-groove, 12-nut.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of side to enter to water hot runner mould, comprise a mold 1, the center of described mold 1 is provided with a vertical nozzle body 2 with heater, the bottom of described nozzle body 2 has several discharging openings 3, usual described discharging opening 3 is circularly and evenly distributed along the periphery of nozzle body 2, each discharging opening 3 is connected with a nozzle head 4 respectively, the spout of described each nozzle head 4 is connected with a die cavity 5 respectively, usually a groove 11 matched with nozzle head 4 type shape is provided with at the charging aperture place of die cavity 5, during assembling, nozzle head 4 is put into this groove 11, make the spout of nozzle head 4 aim at the charging aperture of die cavity 5 simultaneously, during work, injection molding material flows into from the top of nozzle body 2, through hole through nozzle body 2 center enters its bottom, and each discharging opening 3 through its bottom flows into corresponding nozzle head 4, in the die cavity 5 that each nozzle head 4 of final inflow is corresponding.In sum, the structure of entering to water hot runner mould with existing side is basically identical.
As shown in Figure 2, the innovative point that hot runner mould is entered to water in side of the present utility model is mainly that the nozzle of described nozzle head 4 is provided with an elastic washer 6, usually on nozzle head 4, a step is provided with, described elastic washer 6 is just placed on this step, a heat insulating washer 9 is provided with between described elastic washer 6 and die cavity 5, the tail end of described nozzle head 4 is connected with die cavity 5 by a nut 12, namely nut 12 is connected with groove 11, as shown in Figure 3, discharging opening 3 place of the bottom of described nozzle body 2 is provided with an envelope top dressing 7 matched with the tail end of nozzle head 4, after nozzle body 2 and nozzle head 4 are in place, discharging opening 3 on nozzle body 2 just aims at the charging aperture of nozzle head 4 tail end, the bottom of described envelope top dressing 7 is that an envelope tilted to nozzle body 2 axle center waters inclined-plane 8.During concrete assembling, first heat insulating washer 9 and elastic washer 6 are put into groove 11, then put into nozzle head 4, finally by nut 12, nozzle head 4 is connected with groove 11, after in the groove 11 all nozzle heads 4 all being loaded corresponding die cavity 5, nozzle body 2 is stretched into from top to bottom, first the envelope of nozzle body 2 bottom is watered inclined-plane 8 and is touched mutually with nozzle head 4, when nozzle body 2 continues down to stretch, envelope is watered inclined-plane 8 extruding jet nozzle head 4 and is moved to die cavity 5 direction, elastic washer 6 is extruded, until envelope top dressing 7 discounts conjunction completely with the tail end of nozzle head 4, now, each discharging opening 3 on nozzle body 2 aligns with the charging aperture of corresponding nozzle head 4 tail end respectively, simultaneously, due to the extruding of elastic washer 6 pairs of nozzle heads 4, envelope top dressing 7 is fitted tightly with the tail end of nozzle head 4, anti-leak-stopping material.When using a period of time nozzle head 4 to change, only nozzle body 2 upwards need be extracted, then just can remove nozzle head 4 easily, and whole die cavity 5 all need not be removed.
Another innovative point that hot runner mould is entered to water in side of the present utility model is that described die cavity 5 is positioned at and is provided with an alignment pin 10 with the relative position of nozzle head 4 contact site.Both can be positioned die cavity 5 by alignment pin 10, simultaneously also to the pressure of offsetting nozzle head 4 pairs of die cavities 5.The space taken due to alignment pin 10 is less, makes the volume of whole mould less.
