The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
For ease of explanation, direction is as the criterion with shown in Figure 1 in the regulation present embodiment.
See also Fig. 1 and Fig. 2, the utility model die feeding mechanism is used for injecting molding die, and injecting molding die comprises a male model assembly 2, is fixed with a plurality of material pins 3 that draw on the male model assembly 2.The utility model die feeding mechanism comprises a caster 50, and described caster 50 has upper surface and the lower surface that is parallel to each other.The lower surface of the caster 50 recessed slide block groove 51 that is formed with that makes progress, this slide block groove is seen roughly rectangular from forward direction, see the isosceles trapezoid that roughly is up-small and down-big from side direction.The upper surface of caster 50 offers filling mouth containing hole 52 that be communicated with slide block groove 51 and that roughly be square, and caster 50 respectively offers a shoulder groove (figure does not show) in both sides to the left and right in irritating mouth containing hole 52 tops.
See also Fig. 1 and Fig. 3, be equiped with one in the filling mouth containing hole 52 of caster 50 and irritate mouth 80.Irritate mouth 80 and have a base portion 86 that is box-shaped, this base portion 86 is arranged in the filling mouth containing hole 52 of caster 50.The top of base portion 86 both sides to the left and right respectively protrudes out the shoulder groove that a shoulder 85, two shoulders 85 place caster 50.Offer the notes mouth groove 81 that roughly is arc surfaced on the upper surface of filling mouth 80.Irritate and to offer on the mouth 80 from annotating the first flow section of pouring into 82 (belonging to the runner section of pouring into) and the second runner principal piece 83 that mouth groove 81 begins, this first flow section of pouring into 82 and the second runner principal piece 83 all are gradually by the through hole of thin chap.Irritate and to offer on the mouth 80, this injection port 84 thick tapered through hole of serving as reasons since the terminal injection port 84 of the second runner principal piece 83.The second runner principal piece 83 and injection port 84 constitute second runner, and this second runner is a kind of runner.During matched moulds, one draws the end of material pin 3 to extend into the second runner principal piece, 83 ends.
See also Fig. 1 and Fig. 4, be equiped with two slide blocks 90 that slide before and after can be in this slide block groove 51 in the slide block groove 51 of caster 50 symmetrically.From side direction, these slide block 90 rectangular trapezoidal shapes.Two interfaces that slide block 90 has an interface 91, two slide blocks 90 are relative.
When the mould matched moulds, two slide blocks 90 also are close together, and the runner of two slide blocks 90 meets portion 94 and is merged into the runner section of connecing, and the head of the runner section of connecing is coarser than the first flow section of pouring into 82 ends.Two runners middle part 95 is merged into the runner stage casing, and the runner stage casing is narrower than the runner section of connecing; The effect that this runner stage casing attenuates relatively is to save the moulding sizing material.Two runner afterbodys 96 are merged into the runner rear, and the runner rear is coarser than the runner stage casing.Two injection part 97 are merged into the injection road.Two draw material to draw portion 98 is merged into and draws material section, and two draw material portion 99 to be merged into draws material mouthful, and one draws the end of material pin 3 to extend into this draws material mouthful place.The first flow section of pouring into 82, the runner section of connecing, runner stage casing, runner rear and injection road constitute first flow.The runner section of connecing, runner stage casing, runner rear and injection road all are a runner section.The runner section of pouring into constitutes runner with the runner section.
See also Fig. 1, be fixed with a fixed head 60 above the caster 50.Offer the draw-in groove of a circle on the fixed head 60, the middle part of draw-in groove bottom offers a conical taper hole groove 61.The bottom of taper hole groove 61 is connected with a circular hole 62, and this circular hole 62 joins with the notes mouth groove 81 of irritating mouth 80.
Please continue to consult Fig. 1, injecting molding die is formed with first between filling mouth 80, two slide blocks 90 and the male model assembly 2 and isolates die cavity 101 behind matched moulds, and this first end of isolating injection port 84 on die cavity 101 and the filling mouth 80 is communicated with.Be formed with second between two slide blocks 90 and the male model assembly 2 and isolate die cavity 102, this second end of isolating die cavity 102 and injection road joins.It all is an isolation die cavity that the first isolation die cavity 101 and second is isolated die cavity 102.
As mentioned above, because the utility model die feeding mechanism has first flow and two charging runners of second runner, two runners are isolated die cavity 101 and second to first respectively and are isolated injection sizing material in the die cavity 102, thereby can directly finish the injection moulding of two isolation parts on the part, and needn't increase the technology connecting portion, therefore can save design work of technology connecting portion and technology connecting portion and remove operation, therefore can save the man power and material.
Protection domain of the present utility model is not limited to the foregoing description, has multiplely to increase, revise and replace all and should be contained in the claim.For example, on filling mouth 80, can offer two, correspondingly on two slide blocks 90, offer two groups and cave in, form the runner section that is connected with the runner section of pouring into more than two by the runner depression with upper runner with the upper runner section of pouring into; The runner section that forms on two slide blocks 90 does not need in the mould of slide block 90 at some, can directly be opened on the master mold yet; Runner can be for more than three or three; Runner also can be made up of the multistage that is arranged on the different parts of mould; Two slide blocks 90 are seen from the side and might not be wanted rectangular trapezoidal shape, as long as interface 91 shapes of two slide blocks 90 are coincide, can get final product by slitless connection.
