Abstract
It is a kind of to improve the technical method of mould colour changing cleaning efficiency, the technical method of mould colour changing cleaning efficiency can be improved the present invention relates to a kind of, specifically, mould colour changing cleaning efficiency can be improved using this technical method.It is to be achieved through the following technical solutions：During cleaning TOP-TIP runner mold colour changing, the needle switching action at the hot nozzle cast gate of hot flow path carries out do action by control valve control, and with times/second of N ＞ 3.During cleaning TOP-TIP runner mold colour changing, the needle switching action at the hot nozzle cast gate of hot flow path carries out do action by triggering control valve control manually, and with times/second of N ＞ 3.Compared with prior art, the beneficial effect of the art of this patent is：The present invention is due to maintaining the high flow rate inside runner, so having saved scavenging period, having saved cleaning raw material, in the mould being provided with needle valve type hot runner system, improves the efficiency of mould colour changing cleaning, realizes faster scavenging period.
Description
Technical field
The technical method of mould colour changing cleaning efficiency can be improved the present invention relates to a kind of, specifically, this skill is utilized
Art method can improve mould colour changing cleaning efficiency.
Background technology
Plastic mould any color plastic material is added, the production with regard to that can produce corresponding color when producing plastic cement products
Product, so the plastic cement products of a variety of colors used in our daily lifes are to need to add different colours toward in plastic mould
Raw material is produced.After the mould for being configured with TOP-TIP has produced a kind of product, raw material injection is being changed in addition
During a kind of product of color, then need after remaining plastic rubber material of the current residual inside TOP-TIP runner is rinsed well
A kind of plastic material with another color under being molded.
The method of remaining plastic rubber material inside cleaning TOP-TIP runner is that the original that will be produced is added in injection machine
Material, is then constantly applied pressure using screw in injection molding machine and the plastics being newly added is pushed away toward runner the inside, so that current
The plastic rinse rested in TOP-TIP is come out, until rinsing well, the mould that this cleaning process is namely often said is changed
Color.
According to above-mentioned principle, at present the method for cleaning TOP-TIP runner be typically before a mold rear mold open or close
Recycle screw in injection molding machine constantly to apply pressure toward addition new raw material in injection machine under state to develop old raw material.But
In flushing process, open or needle valve type hot runner hot nozzle cast gate is due to being to remain open mode, so hot-fluid
Pressure inside road system runner can be because the cast gate of hot nozzle be reduced in open mode all the time.After pressure is reduced in runner
The flowing velocity that glue is melted in portion will also be reduced, and especially stick to runner inner wall melts glue, so when resulting in the need for more cleanings
Between and cleaning raw material.
The content of the invention
It is an object of the invention to overcome above-mentioned weak point of the prior art, and provide one kind to improve mould and change
The technical method of color cleaning efficiency.
The present invention is to be achieved through the following technical solutions：During cleaning TOP-TIP runner mold colour changing, hot-fluid
Needle switching action at the hot nozzle cast gate in road, do action is carried out by control valve control, and with times/second of N ＞ 3.
During cleaning TOP-TIP runner mold colour changing, the needle switching action at the hot nozzle cast gate of hot flow path,
Do action is carried out by triggering control valve control manually, and with times/second of N ＞ 3.
Compared with prior art, the beneficial effect of the art of this patent is：
The present invention is due to maintaining the high flow rate inside runner, so saved scavenging period, saved cleaning raw material,
It is provided with the mould in needle valve type hot runner system, improves the efficiency of mould colour changing cleaning, realize faster scavenging period.
Brief description of the drawings：
Accompanying drawing 1 is the control needle schematic diagram of control valve of the present invention；
Accompanying drawing 2 is the operating diagram during needle of the invention in a mold switching.
Embodiment：
See accompanying drawing 1, it is a kind of to improve the technical method of mould colour changing cleaning efficiency, in cleaning TOP-TIP runner mould
During having 3 colour changings, the switching of needle 21 action at the hot nozzle cast gate of hot flow path is controlled by control valve 1, and with N ＞ 3 times/
Second carries out do action.
During the cleaning colour changing of TOP-TIP runner mold 3, the switching of needle 21 at the hot nozzle cast gate of hot flow path is moved
Make, controlled by triggering control valve 11 manually, and do action is carried out with times/second of N ＞ 3.
After the mould 3 for being configured with TOP-TIP has produced a kind of product, another color is molded changing raw material
Product when, needle 21 is jammed at the hot nozzle cast gate of mould 3, sees accompanying drawing 2-2, and addition new raw material assembles the pressure inside runner
Increase；When needle 21 is opened at the hot nozzle cast gate of mould 3 suddenly, the high pressure seen inside accompanying drawing 2-3, runner will be forced inside runner
Plastic cement faster flow, internal pressure is released；Needle 21 is jammed at the hot nozzle cast gate of mould 3 again, accompanying drawing 2- is seen
4, addition new raw material makes the pressure inside runner assemble increasing；When needle 21 is opened at the hot nozzle cast gate of mould 3 suddenly, accompanying drawing 2- is seen
1, so go round and begin again, the action of open/closed valve pin is carried out with a kind of very high frequency, maintain the high stream inside runner
Speed, so saving scavenging period, saving cleaning raw material, improves the efficiency of mould colour changing cleaning.
Claims (2)
1. a kind of can improve the technical method of mould colour changing cleaning efficiency, it is characterised in that：In cleaning TOP-TIP runner
During mould colour changing, the needle switching action at the hot nozzle cast gate of hot flow path, by control valve control, and with times/second of N ＞ 3
Carry out do action.
2. a kind of can improve the technical method of mould colour changing cleaning efficiency, it is characterised in that：In cleaning TOP-TIP runner
During mould colour changing, the needle switching action at the hot nozzle cast gate of hot flow path, by triggering control valve control manually, and with N
Times/second of ＞ 3 carries out do action.
