Abstract
The utility model discloses an improved structure for a hot flow-passage system of a jetting and molding die. The utility model is characterized in that a flow-passage combined in a liner which is arranged at the lower of a cylinder of a normal hot flow-passage system is designed into an arc shape, the flow-passage which is provided for inflowing the plastic materials is engaged with the existing space around the liner to be utilized. The utility model dismisses the known designs of right-angle reaction and an inclined plane, and thereby the pressure loss of the injection of the plastic materials can be bottomed out to guarantee the sounder quality of the jetted and formed plastic products.
Description
Technical field
The utility model relates to a kind of structure-improved of ejection shaping die TOP-TIP, when the runner of a kind of circular arc of finger flows into lining with the injection injection nozzle for plastic rubber material especially, it is minimum that this runner can make the pressure loss reduce to, the plastic rubber material delay can not occur and leak the material phenomenon, so the plasthetics quality behind the ejection formation is better.
Background technology
General known plastic cement goes out mould, its top has a cylinder can drive the upper and lower displacement of needle, lining one end of cylinder below can be connected the runner of a hot runner system, can flow into for the plastic rubber material of heater via heating, lining below be a nozzle, and when needle is driven when blocking nozzle downwards by cylinder, plastic rubber material can't be by nozzle place injection in-mold molding, when needle upwards left nozzle by the cylinder drive, plastic rubber material can be injected in the mould with ejection formation by the nozzle place; Yet known runner is because of the problem of space configuration, and therefore the approach of injecting on mostly rectangular refraction or inclined plane the plastic rubber material delay can occur and leak expecting that the plastic rubber material that has solidified at phenomenon or nozzle cast gate place increases phenomenon, thereby influence the quality of ejection formation.
Summary of the invention
The purpose of this utility model provides a kind of structure-improved of ejection shaping die TOP-TIP, mainly be a kind of at the TOP-TIP space utilization and design a kind of runner of circular arc, when flowing into for plastic rubber material, can prevent that plastic rubber material is detained and leaks the plastic rubber material of material phenomenon and the place's curing of reduction nozzle cast gate, thereby guarantee that the plasthetics quality of ejection formation is better.
For achieving the above object, the utility model is taked following design: the structure-improved of this ejection shaping die TOP-TIP, below the cylinder of TOP-TIP, be connected a needle, being connected one in the lining of cylinder below can be for the runner of plastic rubber material inflow, the nozzle of lining lowermost end can place for needle, the nozzle below then is connected plastic mould, and runner is the design of circular arc.The pressure loss that plastic rubber material is injected is reduced to minimum, to guarantee ejection formation plasthetics quality.
In the utility model, the space utilization in the described lining is the best with the arc runner.
Description of drawings
Fig. 1 is a generalized section of the present utility model
The specific embodiment
As shown in Figure 1, the top of the utility model TOP-TIP is a cylinder 1, cylinder 1 below is connected a needle 2, being connected one in the lining 3 of cylinder 1 below can be for the runner 4 of plastic rubber material inflow, lining 3 lowermost ends are injection nozzle 5, and this nozzle 5 can place for needle 2, and nozzle 5 belows then are a plastic mould 6, when the drive of needle 2 by cylinder 1 to top offset and when leaving nozzle 5, the plastic rubber material of heater via heating can inject nozzles 5 with ejection formation via runner 4; It is characterized in that:
Runner 4 is circular arc, cooperate lining 3 peripheral existing space utilizations, forgoing, known right angle reflects or the design on inclined plane, thereby the pressure loss that plastic rubber material is injected is reduced to minimum, the plastic rubber material delay can not occur and leak the material phenomenon, more can not produce the plastic rubber material that has solidified at nozzle cast gate place has the phenomenon of increasing, so can guarantee that the plasthetics quality of ejection formation is better.
In sum, the structure-improved of the utility model ejection shaping die TOP-TIP, with the runner employing circular arc design of TOP-TIP, the pressure loss that plastic rubber material is injected is reduced to minimum, and can reduce the loss of heat simultaneously, thereby make the quality of plastic rubber ejaculate molding better.
