The specific embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
Fig. 1 is extremely shown in Figure 4 to be a specific embodiment of the utility model; Comprise moving clamping plate 1, moving platen 2, cast gate 3, solid plate 4, cover half backing plate 5, push rod 6, ejector pin retaining plate 7; Push pedal 8 and fixed clamping plate 9 are provided with between said fixed clamping plate 9 and the push pedal 8 and cut gating apparatus automatically, and the said gating apparatus of cutting automatically comprises thimble 10 and thimble drive plate; Said thimble drive plate comprises thimble push pedal 11 and thimble fixed head 12; Thimble fixed head 12 is provided with guide hole 13, and said thimble 10 slip caps are connected in the guide hole 13, and the one of which end is fixed between thimble push pedal 11 and the thimble fixed head 12; The other end is provided with cutting knife 14; The blade of cutting knife 14 passes and stretches in the cast gate 3 with the hole that moving platen 2 is provided with through push pedal 8, ejector pin retaining plate 7, solid plate 4 successively in guide hole 13, and for closely being slidingly matched, the Breadth Maximum of said cutting knife 14 cross sections is more than or equal to the Breadth Maximum of cast gate 3 cross sections between the hole that is provided with on thimble 10 and push pedal 8, ejector pin retaining plate 7, solid plate 4 and the moving platen 2; Leave the gap between said thimble fixed head 12 and the push pedal 8; Said gap is more than or equal to the spacing of the terminal and relative cast gate inwall of said cutting knife 14, and said thimble fixed head 12 is provided with groove 15 corresponding to a side of push pedal 8, is provided with spring 16 in the groove 15; Said spring 16 1 ends are fixed on the bottom of groove 15, and the other end is connected with push pedal 8.
Automatically cut the mould of cast gate in the mould of employing said structure, whole injection moulding process comprises following several stages successively:
1, injection phase.With reference to Fig. 1 and shown in Figure 2, be interconnected between die cavity 17 and the cast gate 3, it is interior or concordant with cast gate 3 inwalls that the blade that is provided with cutting knife 14 of thimble 10 stretches into cast gate 3; Do not influence injection molding body and flow into die cavity 17; Simultaneously since between thimble 10 and each hole for closely being slidingly matched, so injection molding body can ostium yet in plugging hole and influence the slip of thimble 10, spring 16 is in the nature relaxed state at this moment; Leave the gap between push pedal 8 and the thimble fixed head 12, this gap length is the thimble stroke.
2, cut automatically the cast gate stage.With reference to Fig. 1 and shown in Figure 2; After injection moulding is accomplished; Push rod 18 acts in the thimble push pedal 11 and promotes thimble push pedal 11 motions; Thimble 10 and thimble fixed head 12 are given in thimble push pedal 11 transmission again, and the blade that makes thimble 10 be provided with cutting knife 14 pushes the cutting cast gate in cast gate 3, and 12 compressions of thimble fixed head spring 16 moves to push pedal 8; Because the Breadth Maximum of cutting knife 14 cross sections is more than or equal to the Breadth Maximum of cast gate 3 cross sections, so cutting knife 14 can cut off being connected between cast gate 3 and the product in the horizontal fully; Because the gap between thimble fixed head 12 and the push pedal 8 is more than or equal to the spacing of the terminal and relative cast gate inwall of said cutting knife 14; Therefore when thimble fixed head 12 touches push pedal 8, the thimble stroke has been enough to make cutting knife 14 to cut off being connected between cast gate 3 and the product in the vertical fully.Promptly accomplished the whole action of in mould, cutting cast gate automatically this moment, and in this stage, push pedal 8 remains motionless, and 16 on spring constantly compresses till thimble fixed head 12 touches push pedal 8.
3, the die sinking stage.With reference to Fig. 3 and shown in Figure 4; This moment, moving platen 2 was separated with solid plate 4; 18 of push rods continue to promote thimble push pedal 11 motions; This moment, thimble fixed head 12 was in contact with one another with push pedal 8, and product that push rod 6 will be cut behind the cast gate for push rod 6 through drive connection transmission layer by layer ejects in die cavity 17, accomplishes the action that ejects of product.
4, the matched moulds stage.With reference to shown in Figure 1, thimble fixed head 12 this moment homing under the elastic force effect of spring 16, entire die also returns to the state in 1 o'clock stage, prepares beginning injection moulding process next time.
Automatically the mould of cutting cast gate in the utility model mould compared with prior art; The beneficial effect that has is: product before the die sinking in mould automatic desprucing; Exempt follow-up manual work and gone the cast gate operation, effectively improved production efficiency, practiced thrift human cost and quality management and control cost greatly; Help the stable of product quality and improve, and then practiced thrift production cost greatly.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
