Description
Technical field
The utility model relates to technical field of mold, is more particularly a kind of cosmetics containers mould.
Background technology
In industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.In brief, mould is the master tool in order to shaping cosmetics containers.
The kind of cosmetics containers is a lot, different, so also a lot of in order to its mould shaping, structure such as the patent CN201420472348.6 of Standard Module records, comprise fixed half and moving half, guide pin bushing is provided with in described cover half, in guide hole in described guide pin bushing, activity is inserted with guide pillar, described guide pillar is arranged on described dynamic model, described cover half arranged outside has cover half pressing plate, described dynamic model arranged outside has dynamic model pressing plate, described cover half is provided with the die cavity that cross section is rounded, described dynamic model is provided with the core matched with cover half upper impression.
For difform cosmetics containers, design difference mainly between core and die cavity, patent CN201020238678.0 such as in order to bottle cap in shaping cosmetics containers records, and die cavity is hemispheric indent, and core is the hemispheric evagination matched with it.Often we only can not arrange a composition pattern on a secondary fixed half and moving half, and many groups can be arranged, so, from sprue to secondary channels, also to disperse many branch flow passages, the design of sprue, secondary channels and branch flow passage, in the process of cast, affect the flow velocity of plastic cement, pressure and heat, finally affect the wall thickness of workpiece, surface smoothness, outward appearance is with or without trace etc.In addition, although can design cooling water flow conduits in mould carries out interior cold, but cooling water flow conduits design is unreasonable, fully not corresponding heat radiation, if mold temperature is higher, sizing can be caused also to affect workpiece surface finish, if also have inabundant cooling and demolding, produce tension, inside workpiece can be caused secretly to split.
Utility model content
The purpose of this utility model is to overcome prior art as above technological deficiency, provide a kind of easy processing, usability good, enhance productivity, the cosmetics containers mould of lifting workpieces quality.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of cosmetics containers mould, comprise fixed half and moving half, described cover half center is run through and is provided with sprue, described cover half is provided with secondary channels on the surface, described sprue and secondary channels are conducted, it is characterized in that, described cover half is provided with the die cavity that cross section is rounded, described dynamic model is provided with the core matched with cover half upper impression, on the sidewall of described die cavity conducting its be provided with branch flow passage, described branch flow passage and secondary channels are conducted, the runner center line center of circle that only described die cavity cross section is round of described branch flow passage.
The all runner designs of the utility model are tree-like branched structure, and an arteries and veins is through, does not have dead angle, add the angle only center of circle and be eccentric entering die cavity, make the flow velocity of plastic cement have certain tangential force, thus decrease the loss of the flow velocity of plastic cement, pressure and heat better, lifting workpieces quality.
As preferably, the runner center line of described branch flow passage and the cross section circle of described die cavity tangent.
In order to make the flow velocity of plastic cement, there is certain tangential force, reduce the loss of the flow velocity of plastic cement, pressure and heat, the runner center line of branch flow passage is cut to optimal selection mutually with the cross section circle of die cavity, and the structural section of most of cosmetics containers is rounded in reality, so the runner applicable surface of design so also can be very wide.
As preferably, cover half corresponds to the cooling water flow conduits that described die cavity rear is provided with through described cover half, dynamic model corresponds to the cooling water flow conduits that described core rear is also provided with through described dynamic model, cooling water flow conduits on cooling water flow conduits on described cover half and described dynamic model intersects vertically, and this joining is just to the central point of described die cavity and core.
The utility model often organize die cavity and core combination rear design one group of cooling water flow conduits passed crosswise, correspond to as far as possible and often organize die cavity and core, also also increase the contact area of heat trnasfer thus, well, cool mould, enhance productivity, also lifting workpieces quality.
Beneficial effect: all runner designs of (1) the utility model are tree-like branched structure, one arteries and veins is through, there is no dead angle, add the angle only center of circle and be eccentric entering die cavity, the flow velocity of plastic cement is made to have certain tangential force, thus decrease the loss of the flow velocity of plastic cement, pressure and heat better, lifting workpieces quality.
(2) the utility model often organize die cavity and core combination rear design one group of cooling water flow conduits passed crosswise, correspond to as far as possible and often organize die cavity and core, also also increase the contact area of heat trnasfer thus, well, cool mould, enhance productivity, also lifting workpieces quality.
