Abstract
A pulse type mold thermo-regulator consists of a pump, a valve, a heating container and a control device and is characterized by another cooling pipeline. A water inlet of the mold thermo-regulator connects to a 4th valve, and the other end of the 4th valve is connected with a pump and a 3rd valve; the pump is connected with the heating container; a water outlet of the heating container is connected to water inlet of the mold; the water outlet of the mold is connected to the 2nd valve, and the other end of the 2nd valve is connected to the 1st and 3rd valve. The other end of the 1st valve is the water outlet of the mold thermo-regulator. With such a structure, the utility model terminates heat exchange of mold during molding, so that high temperature colloidal sol further raises the temperature of mold, improves reproduction rate and reduces double refraction. In cooling phase, cooling water directly brings away the heat in the mold with excellent cooling effect, thus shortening cooling time and improving productivity.
Description
Technical field
The utility model relates to the die heater that a kind of precise injection machine is used.
Background technology
Present prior art, as shown in Figure 1, traditional die heater is made of circulation line 3, water pump 2, heating container 4, cool cycles pipeline 5, water valve 6, and circulation line 3 water inlet ends are connected by water pump 2 and heating container 4, direct and heating container 4 connections in water side; The 1st, mould, cool cycles pipeline 5 is positioned at heating container 4, and its water inlet end has valve 6.Mould backwater in the water quench heating container of the cool cycles of flowing through pipeline 5, cooling water does not directly enter mold cools down.As the mold temperature of setting is 110 degree (temperature of heating container setting just), spends when temperature is higher than 110, and valve 6 is opened and cooled off; As being lower than 110 degree, heater strip heating allows the temperature in the container keep relative stability in 110 degree, carries out heat exchange by the mode of this secondary heat exchange.The problem that exists is: the mold cools down weak effect, and the time is long, and production efficiency is low; And replication rate is low, high birefringence.
Summary of the invention
The purpose of this utility model is: a kind of pulsed die heater is provided, and it interrupts the mold hot exchange when moulding, allow pyrosol further mold temperature be raised, and improves replication rate and lowers birefringence; Directly enter die strip at the cooling stage cooling water and walk heat, good cooling results shortens cool time, enhances productivity.
The utility model is achieved in that a kind of pulsed die heater comprises water pump, valve, heating container and control device, it is characterized in that: also comprise a cooling line, the water inlet end of this die heater is connected with the 4th valve, and the other end of the 4th valve is connected with the 3rd valve with water pump; Water pump is connected with heating container; The water side of heating container is connected with the water inlet end of mould.The water side of mould is connected with second valve, and the other end of second valve is connected with the 3rd valve with first valve, and the other end of first valve promptly is the water side of die heater.
Described the 3rd valve is a check valve, ends direction from the 4th valve to the first valve for it, otherwise is conducting direction.
Described pulsed die heater is characterized in that: described second valve is a by-pass valve control.
Owing to adopt such structure, improve replication rate, lower birefringence and enhance productivity; Open at mould, get sheet after, interrupt the circulation of mould water route, the pyrosol when injection is raised mold temperature, helps improving replication rate and reduces birefringence.At cooling stage, the cooling water of uniform temperature directly pours mould, takes away the heat that moulding produces fast.
When moulding, interrupt the mold hot exchange, allow pyrosol further mold temperature be raised, improve replication rate and lower birefringence; Directly enter die strip at the cooling stage cooling water and walk heat, good cooling results shortens cool time, enhances productivity.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 2, a kind of pulsed die heater comprises water pump 2, valve, heating container 4 and control device (not shown), also comprise a cooling line, [described cooling line is made of inlet pipeline, water return pipeline, the water inlet end of inlet pipeline and the 4th valve 64 are connected, and the water side is connected by water pump 2 and heating container 4; The water inlet end of water return pipeline and heating container 4 are connected, through mould 1, the water side is connected to second valve 62, first valve 61, pipeline is connected by the 3rd valve 63 and inlet pipeline between first valve 61, second valve 62, ] water inlet end of this die heater is connected with the 4th valve 64, the other end of [water inlet end that is cooling line is connected with the 4th valve ,] the 4th valve 64 is connected with the 3rd valve 63 with water pump 2; Water pump 2 is connected with heating container 4; The water side of heating container 4 is connected with the water inlet end of mould 1, and the water side of mould 1 is connected with second valve 62, and the other end of second valve 62 is connected with the 3rd valve 63 with first valve 61, and the other end of first valve promptly is the water side of die heater.The 3rd valve 63 is a check valve, ends direction from the 4th valve to the first valve for it, otherwise is conducting direction.Second valve 62 is used for controlling technology.
Control second valve 62 was closed after control device carried out computing by the die sinking signal of gathering the injection machine mould.
During use, SBR is when mold temperature is lower than the mold temperature of setting, first valve, 61, the four valves 64 are closed, and second valve 62 is opened, make mould 1, heating container 4, second and third valve 62,63 form current heating loop, mould 1 keeps certain temperature.When mould 1 reached the duty of design temperature, heating container 4 quit work.Under this state, the 3rd valve 63 is in the forward conduction state, and the current direction of this die heater inside can be described as the partial circulating state as shown in Figure 3.
After mould 1 was opened, got sheet, second valve 62 was closed, and interrupted mould 1 cooling line 8, and pyrosol is raised mould 1 temperature, helped improving replication rate and reduced birefringence.
At cooling stage, first and second, four valves 61,62,64 open, cooling water makes mould 1 cooling through inlet pipeline, water pump 2, heating container 4, cooling line, takes away the heat in the pyrosol fast, makes the video disc rapid shaping.Under this state, the 3rd valve 63 is in reverse blocking state, and the current direction of this die heater inside can be described as the systemic circulation state as shown in Figure 4.
