Abstract
The utility model discloses a full-automatic hot runner injection molding die which is characterized in that four to eight gates are mounted on a flow distributing plate of a concave die; corresponding numbers of electric heating machine nozzles and water channel holes are fixed on the flow distributing plate and a mold cavity plate; the water channel holes are communicated with a ring-shaped groove on the outer side of a mold cavity; movable mold core strips are mounted on mold cores on a convex die plate; guiding slide blocks are respectively mounted at the upper end and the lower end of the convex die plate; rolling slide blocks are arranged at the upper end and the lower end of an ejector plate; and T-shaped blocks are arranged between the rolling slide blocks. The full-automatic hot runner injection molding die has the benefits that as a hot runner structure and an automatic ejecting and die-releasing structure are adopted, gate handles are not arranged at the bottoms of produced bottle caps; the bottle caps can be automatically detached by using an automatic die-releasing mechanism, and multi-cavity production is achieved; and the full-automatic hot runner injection molding die is suitable for producing masses of plastic caps that need to be continuously produced for a long time, so that the productivity is improved and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of equipment in mould that injection-moulding plastic is used, particularly a kind of full-automatic heat runner injection mold.
Background technology
The injection mold structure complexity of industrial use, it is as follows to have problems: 1, runner is many, and the sizing material that runner is arranged in runner more at most is many more, and the waste material of generation is just many more, and residual in the mould have a very long material handle, improved raw-material cost; 2, the injection mold of existing structure does not have ejecting structure, so after having produced product, needs workman's product of down plucking moulding one by one, and artificial or manipulator remove material, waste time and energy, operating efficiency is low, during the bottle cap demoulding, if misoperation also can cause industrial accident sometimes.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of full-automatic heat runner injection mold at above the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of full-automatic heat runner injection mold, 4 to 8 cast gates are installed on the flow distribution plate of described die, fixedly the electric heating machine mouth and the water channel hole of corresponding number on described flow distribution plate and the cavity plate, and water channel hole is communicated with the cannelure in the die cavity outside, mobilizable core bar is housed on the core on the described convex template, and convex template is equipped with guide runner respectively in two ends up and down, described liftout plate is provided with rolling slide block in two ends up and down, is provided with T type piece in the middle of the described rolling slide block.
Described flow distribution plate and cavity plate are provided with fixing hole, realize interference fit between the electric heating machine mouth of corresponding number and the fixing hole, and each machine mouth power supply lead wire all is connected on the temperature control box.
Described liftout plate and convex template are provided with fixing hole, core passes liftout plate and is connected with the convex mould base bolting with the convex template bottom, movable core bar is housed on the core, and convex template is equipped with guide runner respectively in two ends up and down, and the guiding diagonal brace of end carries out folding about slide block energy edge.
Described liftout plate is provided with rolling slide block in two ends up and down, is provided with T type piece in the middle of the rolling slide block, is bolted to connection between T type piece and the convex mould base.
The utlity model has following beneficial effect:
1, the cooling water channel system of hot flow path structure of Cai Yonging and bottle cap bottom produces behind the bottle cap no heels handle in the mould;
2, during the bottle cap demoulding, adopt the automatic demoulding mechanism of being made up of guide runner, liftout plate, core bar and rolling slide block etc., bottle cap in process of production can auto-separating, need not with artificial hand-manipulated;

The specific embodiment
Below in conjunction with Figure of description the utility model is done following detailed explanation.
As shown in Figure 1, a kind of full-automatic heat runner injection mold, die mainly comprises die socket 2, flow distribution plate 3, cavity plate 4, guiding diagonal brace 20.Punch mainly comprises convex mould base 14, liftout plate 13, and convex template 12, convex template are equipped with guide runner 21 respectively in two ends about in the of 12, and two end faces up and down of guide runner 21 are contained in guide pass respectively.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, die is contained on the fixedly planker of injection machine fixingly, punch is contained on the slip planker of injection machine fixing.During matched moulds, four positioning guide column 16 on the punch, guide runner 21, core 15 are respectively with guide pillar hole 6, guiding diagonal brace 20, cored hole 11 match accordingly on the die.During injection moulding, be heated to of main frame mouth 1 injection of the plastic liquid of fusion from die socket 2, branch to each minute duct 18 through the main aperture road 17 of flow distribution plate 3, each minute, duct 18 correspondences the electric heating machine mouth 10 of corresponding number, this moment, each electric heating machine mouth 10 carried out thermostatic control by power supply lead wire 7 and temperature control box 8, the gap of the plastic liquid of molten condition outside each electric heating machine mouth 10 enters cored hole 11 and core 15 is injection molded into the bottle cap shape.The cooling water of die cooling water channel system, four water channel hole 9 one ends on cavity plate 4 behind the other end of the cannelure of cavity plate side, water channel hole 9, are flowed out by outlet pipe, and bottle cap is cooled off, and save the injection moulding working time.When punch is mobile backward on being contained in movable carriage, the bottle cap that drive is contained on the core 15 separates with die cavity 11, when the punch continuation is mobile backward, guide runner 21 moves by the guide pass of guiding diagonal brace 20 along guide runner 21, progressively open guide runner 21, the bottle cap body outside and guide runner 21 break away from, the thimble that carries in the injection machine ejects simultaneously, promote T type piece 25 and travel forward, the rolling slide block 24 that drives on the liftout plate 13 rotates forward, impels convex template 12 to travel forward, mobilizable core bar 26 ejects forward on the convex template 12, separate with core 22 up to bottle cap, 8 bottle caps come off voluntarily, and whole injection moulding process finishes.When the punch on being contained in movable carriage moved forward, die and punch matched once again, entered the injection moulding state of a new round.
