Description
Technical field
The invention belongs to mould molding field, be specifically related to a kind of die temperance control device.
Background technology
Along with the development of the industries such as household electrical appliances, communication, consumer electronics, automotive trim, photoelectricity, plastic is proposed by consumer
Wall thickness is thinner, structure is more complicated, surface is more attractive, the requirement of the more high aspect of intensity.For traditional injection molding technology,
Using the die temperance control strategy of a kind of constant temperature, owing to being limited by molding cycle, mold temperature is relatively low (the least
In 80 DEG C).In forming process, low mould temperature will cause polymer melt sending out along with cooling in punch die flow process
Raw, form condensate layer because of cooling in advance at cavity wall, the molding of melt can be hindered, reduce filling ability and the transfer energy of melt
Power.Therefore, traditional injection molding technology is difficult to apply to the higher optical articles of molding transparency, surface has micro structure
Composite product and stream that plastic, intensity are higher grow higher ultralong thin walled part or large-scale covering etc..It addition, polymerization
Thing melt cools down prematurely and also will cause plastic surface weld mark, the flowing surface defect such as trace, depression, thus significantly reduces
The surface quality of product, it usually needs polish, the subsequent processing operations such as spraying is covered, this not only adds production cost and
Energy resource consumption, the most also can also bring adverse influence to environment to the health of operator.From analysis above
It can be seen that traditional injection molding technology has been difficult to adapt to the growth requirement of injection industry, the one-tenth that market urgent needs is new
Type technology is to solve above-mentioned formation problems.In recent years, occurring in a certain extent of the new injection molding technologies such as gas was auxiliary, water is auxiliary
Improve the stowage capacity of melt so that can with the plastic of the long ratio of the big stream of molding, but they inherently do not change
Become the filling environment of polymer melt, therefore utilize the residual stress of this technology moulded products relatively greatly, the most excessive injection pressure
Power and dwell pressure also will cause the increase of energy resource consumption and production cost, and the surface defect of goods still cannot thoroughly solve
Certainly.Accordingly, it would be desirable to a kind of new die temperance control device that can solve the problem that drawbacks described above.
Summary of the invention
For overcoming above-mentioned deficiency of the prior art, present invention aim at providing a kind of die temperance control device.
For achieving the above object and other relevant purposes, present invention provide the technical scheme that a kind of die temperance control device,
Including mould, cooling system and heater, the housing of described mould is provided with cooling line, the cooling water of described cooling system
Outlet is connected by the water inlet of pipeline with described cooling line；Described heater includes ceramic core rod, coil and insulating barrier,
Described coil winding is in ceramic core rod, and described insulating barrier is coated with described coil, and described heater inserts the type of described mould
Intracavity.
Preferably technical scheme is: described cooling system includes water tower and cooling-water machine, the coolant outlet of described cooling-water machine
Connected by the water inlet of pipeline with described cooling line, between described water tower and cooling-water machine, pass through pipeline connection.
Preferably technical scheme is: described heater is multiple.
Preferably technical scheme is: described insulating barrier is more than two-layer or two-layer.
Preferably technical scheme is: the outlet of described cooling line is connected with the water inlet of water tower by pipeline.
Preferably technical scheme is: also including temperature sensor and control device, described temperature sensor is conducted heat with mould
Connecting, described temperature sensor is connected with controlling device signal by circuit, and described control device is believed with cooling-water machine by circuit
Number connecting, described control device is connected with the line control unit signal of coil by circuit.
Owing to technique scheme is used, the present invention compared with prior art has the advantage, that
The present invention uses change mould temperature injection molding forming method, uses a kind of dynamic die temperance control strategy, i.e. quickly adds before injection
Mold heat, to realize Gao Mowen injection, subsequently by quickly cooling to shorten molding cycle, thus is not reducing production efficiency
Meanwhile, the inherent shortcoming of traditional injection moulding forming technique is overcome.
