The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Principle of the present utility model is: by bottle lid of cosmetics is inverted to (being Qian font), the appearance of bottle cap is located in male die core, cast gate is arranged on bottle cap inwall, mother module core is on male die core, mother module core is provided with the runner mold insert with runner, runner mold insert coordinates the shaping die cavity that forms bottle cap with male die core, simultaneously in order to be convenient in demoulding, be also provided with master mold push pedal between male die core and mother module core.
Embodiment:
As shown in Figure 2, a kind of injection mould of bottle lid of cosmetics, comprises mother module core 2 and male die core 3, and male die core, below mother module core, is provided with master mold push pedal 4 between male die core and mother module core; Mother module core bottom is provided with runner mold insert 5, and runner mold insert 5 is revolving body, and its one end is fixed on mother module core 2, and male die core 3, through master mold push pedal 4, is inserted in one end; Male die core 3 upper ends are provided with the inner chamber mating with runner mold insert, between the inwall of inner chamber and the outer wall of runner mold insert, have default gap; The bottom surface of the outer wall of the inwall of inner chamber, runner mold insert and master mold push pedal 4 coordinates the shaping die cavity 6 that has surrounded bottle lid of cosmetics, and its shape is Qian font; The center of runner mold insert offers the runner 51 running through from top to bottom, and the lower end of runner 51 is communicated with shaping die cavity 6, and the center of the inwall bottom of shaping die cavity is provided with cast gate 61, and shaping die cavity 6 is communicated with runner by cast gate 61.
Shown in Fig. 2 is the schematic diagram of simplification of the present utility model, a lot of parts all do not illustrate (as template, guide pillar, spring, thimble etc.), and these are all some general parts, so do not illustrate, also the not expression of influence technique scheme, it will be appreciated by those skilled in the art that.
This injection mould carrys out designing mould by bottle lid of cosmetics is inverted to (being Qian font), cast gate can be arranged on to the inwall of bottle cap like this, does not affect the aesthetic feeling of outward appearance.
Because the shape of bottle cap own is uncomplicated, so the creationary runner mold insert 5 that designed of the utility model, runner mold insert, except being provided with runner 51, also becomes a part for core, has surrounded shaping die cavity 6 with the inner chamber of male die core together with master mold push pedal.
Because master mold push pedal 4 is also a part that surrounds shaping die cavity 6; so demoulding meeting is very convenient; specifically male die core 3 moves downward; male die core 3 and master mold push pedal 4 are separated; the moulding of moulding (bottle lid of cosmetics) is stayed on runner mold insert 5; then male die core continues to move downward, and master mold push pedal 4 and mother module core 2 can be separated, and master mold push pedal 4 has just ejected moulding from runner mold insert 5 like this.
Because bottle cap is revolving body, so runner mold insert 5 is also designed to revolving body, processing like this and assembling is all eaily.
In the present embodiment, mother module core is provided with the glue-feeder 21 coordinating with injection machine nozzle, and glue-feeder 21 is communicated with runner 51.Design, on mother module core, so just not be used in the places such as template and has offered glue-feeder, only needs design to step down just, so just than being easier to processing.The shape of glue-feeder 21 need to coordinate with the nozzle of injection machine, also needs gradient etc., and these are all some General Requirements of glue-feeder, have not been described further.
In the present embodiment, the part that runner mold insert 5 coordinates with master mold push pedal is cone, and the angle of its bus lower end and horizontal plane is 85 degree.The shape of cone, the demoulding of being more convenient for.
In the above-described embodiments, the injection mould of a kind of bottle lid of cosmetics that the utility model provides, by bottle lid of cosmetics is inverted to (being Qian font), the appearance of bottle cap is located in male die core, and cast gate is arranged on bottle cap inwall, and mother module core is on male die core, mother module core is provided with the runner mold insert with runner, runner mold insert coordinates the shaping die cavity that forms bottle cap with male die core, simultaneously in order to be convenient in demoulding, be also provided with master mold push pedal between male die core and mother module core.Its beneficial effect is: bottle cap outward appearance do not have cast gate, eject etc. affects the vestige of aesthetic appearance, and mould structure is relatively simple, and Shooting Technique is simple.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
