Abstract
Novel diversion plate valve needle plug, the utility model is related to thermoplastic processing technical fields, are achieved by the following technical solution：Novel diversion plate valve needle plug, it is made of cylinder, flow distribution plate, hot nozzle, hot nozzle and needle, one end of needle is fixed on the movable end of cylinder, the other end of needle passes through flow distribution plate and is fixed on hot nozzle hollow on flow distribution plate, it is plugged in the hole of hot nozzle, hot nozzle with holes is fixed on the other end of hot nozzle, hollow runner is equipped in flow distribution plate, the runner connects with the through-hole that needle moves above and below, and the needle is more than the diameter far from cylinder end close to the diameter of the movable end of cylinder.The utility model by needle plug inside hot runner flow distribution plate plastic cement and hot nozzle be split and separate, alleviate the plastic cement pressure inside hot nozzle, plastic cement can be in fast injection molding to mold cavity before promoting be molded next time, and not will produce shear heat, so as to cause product jaundice, black etc. injection defects generate.
Description
Technical field
The utility model is related to thermoplastic processing technical fields, one kind are referred in particular to during thermoplastic processing, in order to mitigate
The novel diversion plate valve needle plug of the injection pressure in hot runner type intracavitary portion.
Background technology
Hot flow path processing technology be by injection molding machine by after processing plastic grain heating method come ensure runner and
The plastics of cast gate, which are kept molten by, to be molded.In the production excessively of existing product, as shown in Fig. 1, needle 4 is in cylinder 1
Drive under, move back and forth in the hot nozzle 3 so that the plastic grain of molten condition is in a steady stream in the runner 21 inside flow distribution plate 2
It is continuously fed to the channel between needle 4 in hot nozzle 3, into the cavity of mold.In the course of work of hot runner system
In, hot runner type intracavitary sealing carries out sealing by 5 front end plastic emitting position of hot nozzle, and while sealing, the stream inside flow distribution plate 2
The plastic grain of molten condition is still continuously sent into the channel in hot nozzle 3 between needle 4 in road 21, a whole set of in this way
Hot runner system internal cavity pressure is larger, and it is excessive to be easy to cause gate location shear heat when be molded next time, occurs
On product, client does not receive the bad defect of the injection molding such as product jaundice, nigrescence.
Invention content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art places, and provide a kind of novel diversion plate valve
Needle plug.
The utility model is achieved by the following technical solution：Novel diversion plate valve needle plug, by cylinder, flow distribution plate,
One end of hot nozzle, hot nozzle and needle composition, needle is fixed on the movable end of cylinder, and the other end of needle passes through flow distribution plate and consolidates
It is scheduled on hot nozzle hollow on flow distribution plate, is plugged in the hole of hot nozzle, hot nozzle with holes is fixed on the other end of hot nozzle,
Hollow runner is equipped in flow distribution plate, the runner connects with the through-hole that needle moves above and below, and the needle is close to gas
The diameter of the movable end of cylinder is more than the diameter far from cylinder end.
The needle can just be equal to or more than the diameter of the runner in flow distribution plate close to the diameter of the movable end of cylinder.
The utility model by needle plug inside hot runner flow distribution plate plastic cement and hot nozzle be split and separate, subtract
Plastic cement pressure inside light hot nozzle, plastic cement can be in fast injection molding to mold cavity, and not before promoting be molded next time
Will produce shear heat, so as to cause product jaundice, black etc. injection defects generate.
Description of the drawings：
Attached drawing 1 is prior art construction schematic diagram；
Attached drawing 2 is the utility model structure diagram；
Attached drawing 3 is the utility model embodiment schematic diagram.
Specific implementation mode：
See attached drawing 2~3, novel diversion plate valve needle plug, by 6 groups of cylinder 1, flow distribution plate 2, hot nozzle 3, hot nozzle 5 and needle
At one end of needle 6 is fixed on the movable end of cylinder 1, and the other end of needle 6 is across flow distribution plate 2 and in being fixed on flow distribution plate 2
Empty hot nozzle 3, is plugged in the hole of hot nozzle 3, hot nozzle 5 with holes is fixed on the other end of hot nozzle 3, in flow distribution plate 2
Equipped with hollow runner 21, the through-hole that the runner 21 moves above and below with needle 6 connects, and the needle 6 is close to cylinder
The diameter 61 of 1 movable end is more than the diameter far from 1 end of cylinder.
The diameter 61 of movable end of the needle 6 close to cylinder 1 can just be equal to or more than the runner 21 in flow distribution plate 2
Diameter.
When application the utility model, the activity end motion of cylinder 1 drives needle 6 to be moved downward in hot nozzle 3, makes
The plastic grain for obtaining molten condition is extruded from the hole of hot nozzle 5；In the hole that the top of needle 6 protrudes into hot nozzle 5, hot nozzle 5
Front end plastic emitting position carries out sealing, and while sealing, since needle 6 at this time is close to the diameter 61 of the movable end of cylinder 1
Just be movable to the position of runner 21 in flow distribution plate 2, but be equal to close to the diameter 61 of the movable end of cylinder 1 due to needle 6 or
More than the diameter of the runner 21 in flow distribution plate 2, also the hole of runner 21 is blocked, plug effect is formed, closes in flow distribution plate 2
Runner 21, inside hot runner flow distribution plate 2 plastic cement and hot nozzle 5 be split and separate, alleviate the plastic cement inside hot nozzle 5
Pressure solves the problems, such as the injection defects such as resulting product jaundice, nigrescence.
