Abstract
The invention discloses a mould variable flow cooling device which is mainly consists of a cooling water pump, a solenoid valve, a mould, a water flow controller and an injection molding machine controller, wherein the cooling water pump is connected with the mould through the solenoid valve, the cooling water pump, the solenoid valve and the mould form a cooling water circulation loop, one path of pressurized water from the cooling water pump is directly introduced into the mould, and the other path of the pressurized water is introduced into the mould through the solenoid valve and then flows back to the cooling water pump from the mould; and the injection molding machine controller is connected with the water flow controller which is connected with the solenoid valve. The invention ensures that cooling water flow is matched with heat flow in the mould so as to ensure stable internal temperature of the mould and the evenness of disc temperature and quickly take away mould temperature, thereby realizing the purpose of quickening injection molding periods.
Description
Technical field:
The present invention relates to a kind of injector Water cooling device of die, relate in particular to a kind of mould variable flow cooling device.
Background technology
Along with the capacity of CD and improving constantly of the speed of service, the parameter index of disc is required more and more harsher, the especially warpage of disc and birefringence index.Although can reach by prolonging the injection mo(u)lding time purpose of basic controlling warpage and birefringence index, can cause the production cycle to strengthen at double, production cost rises, and two indexs can't be stablized control.At an injection molding cycle, heat flow is unsettled in the mould, the common mould constant flow type of cooling can't guarantee the uniformity of the stable and disc temperature of mould inside temperature, higher internal stress residue be can therefore produce for the so ultrathin moulding of disc, thereby warpage and the birefringence index exceeding standard of disc made.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of mould variable flow cooling device be provided.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions: a kind of mould variable flow cooling device, it mainly is comprised of cooling water pump, magnetic valve, mould, water flow controller and controller of plastic injection molding.Wherein, cooling water pump links to each other with mould by magnetic valve, and cooling water pump, magnetic valve, mould form a cooling water circulation loop, and cooling water pump pressure (hydraulic) water out has one tunnel straight-through mould, mould is led to through magnetic valve in another road, then is back to cooling water pump from mould.Controller of plastic injection molding links to each other with water flow controller, and water flow controller links to each other with magnetic valve.
Further, described cooling water pump is High-temperature Magnetic Pump.Described magnetic valve is double-flow-rate electromagnetic valve.
The invention has the beneficial effects as follows,
1, the present invention makes that heat flow is complementary in cooling water flow and the mould, thereby guarantees the uniformity of the stable and disc temperature of mould inside temperature, takes away fast mold temperature simultaneously, reaches the purpose of accelerating injection molding cycle.
2, the present invention can also be applied in other ultrathin injection moulding aspects except the injection mo(u)lding that is applied to CD.
Description of drawings
Fig. 1 is the mould variable flow cooling device control principle drawing;
Fig. 2 is cooling water flow control curve map.
The specific embodiment
As shown in Figure 1, mould variable flow cooling device of the present invention mainly is comprised of cooling water pump, magnetic valve, mould, water flow controller, controller of plastic injection molding, wherein mould and controller of plastic injection molding are the own parts of injection machine, and cooling water pump is High-temperature Magnetic Pump, and magnetic valve is double-flow-rate electromagnetic valve.Cooling water pump links to each other with mould by magnetic valve, and cooling water pump, magnetic valve, mould form a cooling water circulation loop, and cooling water pump pressure (hydraulic) water out has one tunnel straight-through mould, and mould is led to through magnetic valve in another road, then is back to cooling water pump from mould.Controller of plastic injection molding links to each other with magnetic valve by water flow controller.
As shown in Figure 2, the course of work of the present invention is as follows: the cooling water flow control model: controller of plastic injection molding also passes to water flow controller with control signal when sending the injection moulding control instruction, the aperture of water flow controller control magnetic valve.In the demould time section, the mould empty calory adds, and magnetic valve is not opened, and cooling water flows to mould by straight-through pipeline, and this moment, discharge was minimum; In the feed time section, heat adds gradually, and magnetic valve is opened the a-road-through road, and cooling water flow strengthens; In the cool time section, magnetic valve is opened two paths, and this moment, cooling water flow be maximum, quickening mold cools down speed.
The present invention reduces cooling water flow, energy savings without the injection phase that adds heat; In the reinforced stage, along with the adding of high-temperature material, mold temperature uprises, strengthened cooling water flow this moment, accelerate to take away gradually heat, but cooling water flow was not maximum stream flow this moment, can prevent that like this mould from too cooling off with the material contact-making surface, cause the disc internal stress bigger than normal; At cooling stage, cooling water flow is maximum, takes away heat with the fastest speed, reduces molding cycle.
