Application number be 201210568949.2 patent of invention disclose a kind of runner plate of plastic tray injection mold, , comprise press plates, gum-injecting port is had in press plates, press plates installs runner plate, runner frame is installed in runner plate, hole for injecting glue is had in runner frame, gum-injecting port communicates with hole for injecting glue, described runner frame is M shape runner frame, described M shape runner frame comprises upper runner, lower flow channel, left runner, right runner, upper left runner, upper right runner, lower-left runner and bottom right runner, described left runner and right runner be shorter in length than upper left runner, upper right runner, lower-left runner and bottom right runner, perpendicular left end runner is shaped with left runner one, right runner one is shaped with perpendicular right-hand member runner, all runners are all shaped with gum outlet, gum outlet communicates with the die cavity of injection mold.Because left end runner and left runner are mutually vertical, must produce material liquid flowing channel and impact and backflow, affect injection moulding.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of flow channel of injection die plate structure, and the distance of each gum outlet of plastic passages that heat is melted is close, and makes to avoid in plastic flow process producing to impact, and ensures product quality.
For achieving the above object, the utility model provides following technical scheme: a kind of flow channel of injection die plate structure, comprise press plates, press plates center starts there is gum-injecting port, below press plates, runner plate is set, runner frame is installed in runner plate, the hole for injecting glue corresponding with gum-injecting port is provided with in runner frame, gum-injecting port communicates with hole for injecting glue, described runner frame is M shape runner frame, runner frame comprises upper runner, lower flow channel, left runner, right runner, upper left runner, upper right runner, lower-left runner and bottom right runner, it is characterized in that: setting upper runner, lower flow channel, left runner, right runner is sprue, setting upper left runner, upper right runner, lower-left runner, bottom right runner is secondary channels, the end of sprue is respectively equipped with the turnout of V-arrangement, turnout is formed by the runner that two are obliquely installed with sprue, wall scroll runner adds that the length of sprue equals the length of wall scroll secondary channels, the end of secondary channels and runner is respectively equipped with gum outlet.
Preferably, described sprue, secondary channels and turnout are respectively equipped with some independently water backs, turnout is provided with the water back of single V-arrangement, and sprue is provided with the water back of a kidney-shaped, and secondary channels is provided with the water back of two kidney-shapeds.
Preferably, described press plates and runner plate are all fixed on cover half, are combined with dynamic model below cover half, and dynamic model four sides are respectively equipped with cylindrical installing hole.
By adopting technique scheme, achieve following advantage: because runner and sprue are not vertically disposed, and be shaped as the inclination angle of a buffering transitional function, therefore stream of plastic is out-of-date avoids the recoil strength producing resilience, but soft be transitioned on runner, the plastics that such setting can allow two runners get are relatively uniform, and injection moulding product each several part density is out harmonious, ensure that the bulk strength of pallet.

Detailed description of the invention
A kind of flow channel of injection die plate 2 structure, comprise press plates 1, press plates 1 center starts there is gum-injecting port 1a, runner plate 2 is set below press plates 1, be provided with runner frame 3 in runner plate 2, be provided with the hole for injecting glue 3f corresponding with gum-injecting port 1a in runner frame 3, gum-injecting port 1a communicates with hole for injecting glue 3f, described runner frame 3 is M shape runner frame 3, and runner frame 3 comprises upper runner 3b1, lower flow channel 3b2, left runner 3b3, right runner 3b4, upper left runner 3a1, upper right runner 3a2, lower-left runner 3a3 and bottom right runner 3a4, setting upper runner 3b1, lower flow channel 3b2, left runner 3b3, right runner 3b4 is sprue 3b, setting upper left runner 3a1, upper right runner 3a2, lower-left runner 3a3, bottom right runner 3a4 is secondary channels 3a, the end of sprue 3b is respectively equipped with the turnout 3c of V-arrangement, turnout 3c is formed by the runner 3c1 that two are obliquely installed with sprue 3b, wall scroll runner 3c1 adds that the length of sprue 3b equals the length of wall scroll secondary channels 3a, and the end of secondary channels 3a and runner 3c1 is respectively equipped with gum outlet 3e.Because runner 3c1 and sprue 3b is not vertically disposed, and be shaped as the inclination angle of a buffering transitional function, therefore stream of plastic is out-of-date avoids the recoil strength producing resilience, but soft be transitioned on runner 3c1, the plastics that such setting can allow two runner 3c1 divide are relatively uniform, injection moulding product each several part density is out harmonious, ensure that the bulk strength of pallet.
Wherein, sprue 3b, secondary channels 3a and turnout 3c are respectively equipped with some independently water back 3d, turnout 3c is provided with the water back 3d of single V-arrangement, and sprue 3b is provided with the water back 3d of a kidney-shaped, and secondary channels 3a is provided with the water back 3d of two kidney-shapeds.Water back 3d independently can ensure various can being effectively heated, and avoids the oversize partial heat supply caused of heating tube to cause the problem of plastics solidification not.Turnout 3c is arranged water back 3d and the turnout 3c form fit of V-arrangement, heating evenly.
Wherein, press plates 1 and runner plate 2 are all fixed on cover half 4, are combined with dynamic model 5 below cover half 4, and dynamic model 5 four sides are respectively equipped with cylindrical installing hole 5a.Installing hole 5a facilitates inserted link to insert, being separated of very convenient cover half 4 and dynamic model 5 in die hoisting or handling process, and the words that all arrange of four sides can avoid the displacement of mould all directions in handling process, ensure safety.
