Abstract
The utility model discloses a variable flow cooling device for a die, which mainly comprises a cooling water pump, an electromagnetic valve, the die, a water flow controller and an injection molding machine controller, wherein the cooling water pump is connected with the die through the electromagnetic valve; a cooling water circulation loop comprises the cooling water pump, the electromagnetic valve and the die; and a path of pressurized water flowing out of the cooling water pump directly flows to the die, and another path of the water flows to the dir through the electromagnetic valve and then reflows to the cooling water pump from the die. The injection molding machine controller is connected with the water flow controller; and the water flow controller is connected with the electromagnetic valve. The flow rate of cooling water is matched with the heat flow rate in the die, and therefore, the utility model ensures the stability of temperature inside the die and the uniformity of temperature of a disk sheet, quickly takes the heat of the die away, and achieves the purpose of quickening the injection molding and forming period.
Description
Technical field:
The utility model relates to a kind of injector mould water-cooling apparatus, relates 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.Though can reach the purpose of basic controlling warpage and birefringence index by the prolongation injection mo(u)lding time, 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 current amount type of cooling can't guarantee the uniformity of the stable and disc temperature of mould inside temperature, can therefore produce higher internal stress residue for the so ultrathin moulding of disc, thereby make the warpage and the birefringence index exceeding standard of disc.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of mould variable flow cooling device is provided.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: a kind of mould variable flow cooling device, it mainly is made up 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 are formed a cooling water circulation loop, and the pressure (hydraulic) water that cooling water pump comes out has one tunnel straight-through mould, mould is led to through magnetic valve in another road, is back to cooling water pump from mould then.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 a High-temperature Magnetic Pump.Described magnetic valve is a double-flow-rate electromagnetic valve.
The beneficial effects of the utility model are,
1, the utility model 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 mold temperature fast simultaneously, reaches the purpose of accelerating injection molding cycle.
2, the utility model 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 mould variable flow cooling device control principle figure;
Fig. 2 is cooling water flow control curve map.
The specific embodiment
As shown in Figure 1, the utility model mould variable flow cooling device mainly is made up 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, cooling water pump is a High-temperature Magnetic Pump, and magnetic valve is a double-flow-rate electromagnetic valve.Cooling water pump links to each other with mould by magnetic valve, and cooling water pump, magnetic valve, mould are formed a cooling water circulation loop, and the pressure (hydraulic) water that cooling water pump comes out has one tunnel straight-through mould, and mould is led to through magnetic valve in another road, is back to cooling water pump from mould then.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 utility model 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 reinforced time period, heat adds gradually, and magnetic valve is opened a paths, 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 utility model adds the injection phase of heat in nothing, reduces cooling water flow, energy savings; 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 heat gradually, but cooling water flow was not a 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.
