As shown in figure 3, the hydraulic control system includes pressure dwelling loop, wherein pressure dwelling loop includes sequentially connected Oil absorption filter 1b, hydraulic pump 1d, check valve 1e, reversal valve 1f, hydraulic control one-way valve 1g and electric contact type pressure gauge 1h, it is described The two sides hydraulic control one-way valve 1g respectively with the rod chamber of hydraulic cylinder 70 and rodless cavity and connect, the side of the hydraulic pump is simultaneously connected to overflow Valve 1c, oil liquid is through overflow valve oil return box 1a.
The design can realize injection molding and shaping while carry out, and be now described below:
Fig. 1 show mold clamping state, and under the action of injector helical screw agitator, high-temperature fusion plastics are by injection molding portion Sprue 81 enters, then through runner 82 by runner cast gate injection type chamber 30, into the molten plastic in type chamber 30 through one section The pressure maintaining curing molding of time;As shown in Fig. 2, under the action of pull-rod spring 60, the first die joint is opened, type core when die sinking Plate 4 and cavity plate 3 move to left, and when moving to left to the step of 6 left end of pull rod, the stopping of being obstructed of core plate 4 is moved to left, and cavity plate 3 continues It moves to left, the second die joint is opened, at this point, can be taken off the plastics in running channel, is convenient for injection molding next time;It is curved after parting Bent part product remains in type chamber 30, and rotary shaft 11 rotates 180 ° at this time, and type intracavitary product in lower end is transferred to upper end, then moves Movable plate 2 moves to right, driven mold molding.
After molding, correction body 7 is controlled by hydraulic control system and is moved to left to upper end type chamber 30, bool product is compressed and carries out Correction, this process are achieved in that the right position reversal valve 1f must conduct, and oil liquid drives hydraulic cylinder to export through hydraulic control one-way valve 1g Bar moves to left, and when oil liquid pressure rises to the set pressure of electric contact type pressure gauge 1h, position must be conducted in reversal valve 1f, hydraulic 1d off-load is pumped, hydraulic cylinder pressure maintaining, when pressure drops to the pressure of electric contact type pressure gauge 1h setting, the left position reversal valve 1f obtains electric Conducting, hydraulic pump 1d to hydraulic oil supply cylinder, go up by pressure, and hydraulic cylinder output rod moves to right, thus realize correction body 7 move to left, pressure maintaining, The working cycles moved to right.
While the product of the upper end is corrected the correction pressure maintaining of body 7, under the type chamber 30 of lower end continues with the cooperation of injection molding portion The injection molding of one bool product, molding rear mold die sinking, upper end passes through fixed base 1 through the bool product of overcorrection On push rod 10 push push plate 32, then ejected by ejector beam 31, become finalization product, and the product of lower end injection molding Continue to drive rotation to be corrected by rotary shaft 11, be recycled with this, in the above process, time and the correction of product curing molding Dwell time is identical, with guarantee molding and shaping can synchronous progress, in fact, can regard the shaping of bool to being solidified into as The extension of type time realizes marginal not modeling, side correction, on the one hand improves production efficiency, another party by using the measure of correction unit Face lengthening curing time improves the Forming Quality of product to further decrease the deflection of bool product.
Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing What is shown is also one of embodiments of the present invention, and actual structure is not limited to this.So if the common skill of this field Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution Similar frame mode and embodiment, are within the scope of protection of the invention.
