Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.The element described in an accompanying drawing of the present invention or a kind of embodiment and feature can combine with the element shown in one or more other accompanying drawing or embodiment and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process in illustrating.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not paying creative work, all belongs to the scope of protection of the invention.
In the following embodiment of the present invention, the sequence number of embodiment and/or sequencing are only convenient to describe, and do not represent the quality of embodiment.The description of each embodiment is all emphasized particularly on different fields, in certain embodiment, there is no the part described in detail, can see the associated description of other embodiments.
The present invention discloses a kind of laminated mould, as shown in Figure 1, comprise stuck-module 1, active module 2 and intermediate module 3, intermediate module is arranged between stuck-module and described active module, during matched moulds, active module and intermediate module move, until described intermediate module and stuck-module form the first die cavity, active module and described intermediate module form the second die cavity to the direction near stuck-module; Need be appreciated that the first die cavity and the second die cavity are formed simultaneously.
In intermediate module, be also provided with injection molding channel, as shown in Figure 2, injection molding channel comprises: sprue 21, has main charging aperture 211, first main discharging opening 212 and the second main discharging opening; Runner for the first time, have charging aperture 221 and for the first time discharging opening 222 for the first time, charging aperture is communicated with the first main discharging opening for the first time; Second time runner, have second time charging aperture and second time discharging opening, second time charging aperture is communicated with the second main discharging opening; First discharge nozzle 23, connects first time discharging opening, to the first die cavity feed; Second discharge nozzle, connects second time discharging opening, to the second die cavity feed; Wherein, locating ring 24 is also provided with outward at main charging aperture.Need to understand, first time runner and the structure of for the second time runner time identical, therefore the material flowed out from sprue, average inflow first and second secondary fluid course, can ensure that the first die cavity is identical with the amount of the raw material that the second die cavity obtains like this, thus make the structure that in two die cavitys, injection moulding completes identical.Certainly, identical in order to ensure the inventory in each secondary fluid course, the height of each main discharging opening also needs identical.In figure bis-, label has only write out the first main discharging opening, for the first time charging aperture, the first discharge nozzle etc., and corresponding second main discharging opening, second time charging aperture etc., because of symmetrical in the drawings with it, so there is no mark.
Preferably, the sprue of injection molding channel is arranged in the plane perpendicular with active module mobile axis direction of intermediate module.Such as, during the horizontal die sinking of injection machine, the sprue of injection molding channel can be arranged in the perpendicular of the intermediate module of laminated mould.
The main charging aperture of sprue can be set to have relative to the central axis of sprue main body the bending being less than 90 °.Such as, main charging aperture can be arranged on top surface central authorities become 60 ° angle (as Fig. 3) with the central axis of sprue main body.The central axis of the central authorities and sprue main body that also can be arranged on forward and backward surface or lower surface becomes to be less than the angle of 90 °.This is conveniently connected with the nozzle of outside inclined injection machine, evenly injects.
When not having bending (0 °), namely sprue extends to outside opening at intermediate module centre straight ahead.As shown in Figure 4.
In order to ensure that the first die cavity and the second die cavity can be formed simultaneously, the speed that intermediate module leaves stuck-module movement is less than the speed that described active module leaves described stuck-module movement.
Preferably, described active module leaves the ratio of the displacement and speed that the displacement of described stuck-module movement and speed leave stuck-module movement with intermediate module is 2:1.
Preferably, intermediate module is provided with gear train, described stuck-module and described active module are provided with tooth bar, respectively from the different gear matches in gear train, described first die cavity and described second die cavity are formed simultaneously.Can know, can, by the gear of different size, make active module different to the speed that stuck-module is close with intermediate module, thus two die cavitys are formed simultaneously.
In the optional embodiment of one, the nozzle of injection machine is towards the main charging aperture of this mould.The nozzle of injection machine is tapered mouth, in tapered mouth, be arranged with tapered core, and tapered core supports closed described tapered mouth by spring; The oil cylinder of injection machine makes nozzle near main charging aperture, and described tapered core is pressed on the locating ring top to main charging aperture, makes to form space between tapered core and described tapered mouth, injection charging.
In order to prevent material from solidifying before living in die cavity, at sprue, secondary fluid course and discharge nozzle outer wall, be provided with heater.
At least one beneficial effect of the present invention is: material enters injection molding channel by intermediate module, without the need to through die joint, makes each cavity pressure more balanced, meanwhile, avoids the sealing leak problem of material during die sinking.Mold cavity configuration of the present invention is simply efficient, and flow passage structure is simple, can simultaneously can to two die cavity feedings, and each secondary fluid course structure is identical, and therefore each discharge nozzle load is identical, and two die cavitys can be formed again simultaneously, improve operating efficiency
