Specific embodiment

The utility model is described in further details with reference to the accompanying drawings and detailed description.

As Figure 1-Figure 4, in an injection mold, the injection mold includes upper die plate to the utility model embodiment one 10th, lower template 20, generally within die cavity therebetween, the sprue portion 3 of the present embodiment one is substantially then the present embodiment one Through upper die plate 10.For the present embodiment one, it mainly includes sprue portion 3, distributary division 4, cover plate 5.Need to illustrate in advance , it is dismountable annexation between each critical piece of the present embodiment one, in other embodiments, at least two is adjacent Can also be structure as a whole between part.

Wherein, then as shown in Figure 6, Figure 7, sprue portion 3 is in the form of a column, and is alongst provided with for by molten plastic Sprue 31 and for the first heating flow channel 32 by deep fat.

Again as shown in Figure 8, Figure 9, distributary division 4 is plate-like, is provided with the runner 42 of at least one flute profile, and be provided with second plus Hot flow path 41, similarly, the second heating flow channel 41 is also for water conservancy diversion deep fat.

Again as shown in Figure 10, cover plate 5 is covered on runner 42, and the runner 51 of flute profile also is provided with cover plate 5, with The correspondence of runner 42, to expand flow.If there is the accidents such as blocking during production, opening cover plate 5 can clear up sprue 31 and divide Improper molten plastic on runner 42, runner 51.

Also, distributary division 4 is provided with hot mouth cast gate 7, it is easy to connect hot mouth, hot mouth cast gate 7 is connected with runner 42；It is preferred that Ground, hot mouth cast gate 7 is provided with internal thread, is threadedly coupled with hot mouth, and according to hot mouth needs, hot mouth cast gate 7 can be straight mouth cast gate Or latent pressure type cast gate.

Sprue portion 3 and distributary division 4 are connected, and preferably the lower end of sprue portion 3 is shunk and is provided with external screw thread, correspondingly, point Stream portion 4 is provided with screw, after the two threaded connection, also to cause that sprue 31 is connected and the first heating stream with runner 42 Road 32 is connected with the second heating flow channel 41.

First heating flow channel 32 or the second heating flow channel 41 are in communication with the outside, specific such as Fig. 9 institutes to facilitate water conservancy diversion deep fat Show, 411, oil inlet 412 of an oil-out is provided with the side of distributary division 4, to be input into two respectively, export deep fat Oil pipe 6 is connected.

Further, the present embodiment one also includes location-plate（Or referred to as mould location-plate）1st, closure 2.Wherein, As shown in figure 5, relative with distributary division 4 one end in sprue portion 3 of closure 2, its Main Function is to seal first to add Hot flow path 32, because first heating flow channel 32 is the open architecture of a fluted body, closure on the upper end end face in sprue portion 3 2 coverings are connected thereon and with sprue portion 3, so that the first heating flow channel 32 is fully sealed.Preferably, closure 2 and master Flow path portion 3 is threadedly coupled, and sprue portion 3 shrinks upper end and is provided with external screw thread, is then screwed into the screw of closure 2.Location-plate 1 Center is provided with the endoporus with outer inclined-plane, and the excircle of closure 2 is also ramp structure, whereby, the insertion location-plate 1 of closure 2 Endoporus in, the two cooperation so that location-plate 1 stabilization and be movably arranged at around closure 2.

As shown in figures 11-13, the utility model embodiment two includes the locating module 30 for injection molding machine nozzle positioning （Similar to the sprue portion of the present embodiment one）, distributary division 40, unlike, the present embodiment also includes hot mouth 701, and hot mouth The heating flow channel for the deep fat that circulates also is provided with 701, this illustrates the heating flow channel for by deep fat of the present utility model simultaneously Without limitation, can be changed as needed.In addition, the structure chart of the present embodiment two also presents the entirety of heating flow channel 401 Structure, the overall structure for the hot flow path 400 by molten plastic.

To sum up, the utility model is in order to realize can be with fast assembling-disassembling, according to mould product structure, runner design into can be with Multiple modules of Combinatorial resolution, runner design and installation can be dismounted on mold parting surface when the die joint of mould is opened Hot flow path.The cover plate of quick cleaning is designed on distributary division, when there is unexpected PVC decomposition, use can be simply taken apart In the cover plate of runner cleaning, sprue, runner and cast gate are directly cleared up, continue to produce after Fast Installation, and TOP-TIP Will not scrap and damage.Cover plate is that pattern has clamp force to ensure the sealing of whole flow passage system.

Analysis shows, the utility model heats molten plastic using high temperature oil, and not only cost of implementation is relatively low, and temperature control System stabilization.
