Description

A kind of injection mould template
Technical field
The utility model relates to mechanical-moulded technical field, refer in particular to a kind of mold materials consume low, to mould gelating material waste few, accelerate filling velocity and the flow rate of plastics simultaneously, shorten the injection mould template of molding cycle.
Background technology
Injection moulding is the main moulding process of one and the method for plastic part, be in a high voltage state by plastic melt with high speed injection in closed die cavity, after pressurize, cooling and shaping, obtain with die profile on all four plastic products.Injection mold is the important process equipment during plastic injection is produced, and its structure is generally made up of six Iarge-scale system, forms the fixed half and moving half part of mould respectively.Running gate system is a main composition system in injection mould structure, refers to by the feeding-passage nozzle of injector to die cavity in mould, is generally made up of sprue, runner, cast gate and slag well.In traditional injection mold, sprue bush is mounted in top clamping plate, caster and in mother module core, by runner channel, plastics is injected mold cavity and realizes injection mo(u)lding.Coagulate material due to running gate system and belong to process residue, need after shaping manually by its from product cut off or in forming process by the mechanisms such as runner ejector pin directly and product automatically cut off, therefore, how appropriate design mould structure, reduce running gate system solidifying material volume as far as possible, reduce raw materials for plastics production consumption, for reduction production cost, increase economic efficiency and have a very big significance.
Utility model content
The utility model object be in order to overcome the deficiencies in the prior art provide a kind of mold materials consume low, to mould gelating material waste few, accelerate filling velocity and the flow rate of plastics simultaneously, shorten the injection mould template of molding cycle.
For achieving the above object, the technical solution adopted in the utility model is: a kind of injection mould template, comprises caster, top clamping plate, sprue bush; The center of described top clamping plate is provided with the first through hole; The center of described caster is provided with type conical bench hole, and described type conical bench hole is made up of taper hole and step through-hole; The bottom of the step through-hole of described caster is provided with mother module core, and the center of described mother module core is provided with the second through hole; Described sprue bush is stepped, and the diameter of the head of described sprue bush is greater than the diameter of the second through hole; The head of described sprue bush is placed on gap form in the straight hole in type conical bench hole, the lower end of described sprue bush is assemblied in the second through hole of mother module core with interference fits form, the center of described sprue bush is provided with third through-hole, and described third through-hole is communicated with the nozzle of injector and forms running gate system sprue.
Preferably, the upper surface of described mother module core and the lower surface of step through-hole concordant.
Preferably, described sprue bush trip bolt is fixed on the upper surface of mother module core through the head of sprue bush.
Preferably, the head of described first through hole is provided with counter sink, is provided with centring ring in described counter sink, and the center line of described centring ring and the center line of counter sink are on same center line, and described centring ring is fixed on top clamping plate by hold-down screw.
Preferably, the head of described third through-hole is provided with ball recess, for being connected with the nozzle of injector.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Injection mould template described in the utility model under equal conditions, reduces diameter and the length of the third through-hole in sprue bush, and the volume making running gate system coagulate material reduces, thus reduces the cost of mold materials; Filling velocity and the flow rate of plastics can be increased simultaneously, shorten molding cycle.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is sprue bush and the template assembling schematic diagram of injection mould template described in the utility model;
Wherein: 1, moulding; 2, caster; 3, trip bolt; 4, top clamping plate; 5, centring ring; 6, the first through hole; 7, sprue bush; 8, hold-down screw; 9, mother module core; 10, the solidifying material of running gate system.
detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is injection mould template described in the utility model, comprises caster 2, top clamping plate 4, sprue bush 7; The center of described top clamping plate 4 is provided with shoulder hole, and described shoulder hole is followed successively by counter sink and the first through hole 6 from outside to inside, and the diameter of described counter sink is greater than the diameter of the first through hole 6; Be provided with centring ring 5 in described counter sink, the described center line of centring ring 5 and the center line of counter sink are on same center line, and described centring ring 5 is fixed on top clamping plate 4 by hold-down screw 8; The center of described caster 2 is provided with type conical bench hole, and described type conical bench hole is made up of taper hole and step through-hole; The bottom of the step through-hole of described caster 2 is provided with mother module core 9; The upper surface of described mother module core 9 is concordant with the step surface of step through-hole, and the center of described mother module core 9 is provided with the second through hole; Described sprue bush 7 is stepped, and the diameter of the head of described sprue bush 7 is greater than the diameter of the second through hole; The head of described sprue bush 7 is placed on gap form in the straight hole in type conical bench hole, the lower end of described sprue bush 7 is assemblied in the second through hole of mother module core 9 with interference fits form, the center of described sprue bush 7 is provided with third through-hole, the head of described third through-hole is provided with ball recess, and described sprue bush 7 head that trip bolt 3 passes sprue bush 7 is fixed on the upper surface of mother module core 9; Described third through-hole is communicated with the nozzle of injector and forms running gate system sprue.
