Description
Technical field
The utility model relates to a kind of injection mold, relates in particular to a kind of ball-type injection mold, belongs to processing and manufactures and designs the field.
Background technology
Along with the development of industrial technology, high-end industrial production is come into people's life gradually, and the production of the product of various designs and design all need through drawing design, mould shape and manufacturing several steps.Injection mold is one of most widely used mould in the current industrial production, is a kind of processing method of using when producing some complex-shaped parts in batches.Specifically the finger material that melts that will be heated is injected die cavity by high pressure, behind cooling curing, obtains formed products.Injection mold is made up of dynamic model and cover half two parts, and dynamic model is installed on the moving die plate of injection (mo(u)lding) machine, and cover half is installed on the fixed form of injection (mo(u)lding) machine.Dynamic model and cover half closed formation running gate system and die cavity when injection moulding, dynamic model separates in order to take out plastic products with cover half during die sinking.
Though the structure of injection mold may be ever-changing because plastics variety is different with the shape of performance, plastic products and the type of structure and injector etc., basic structure is consistent.Mould mainly is made up of running gate system, thermoregulating system, forming part and constitutional detail.Wherein running gate system and forming part are and the direct contact portion of plastics, and change with plastics and goods, are the most complicated in the mold, change maximum, require processing fineness and the highest part of precision.Running gate system refers to that plastics enter runner section before the die cavity from nozzle, comprise sprue, cold slug well, runner and cast gate etc.Forming part refers to constitute the various parts of article shape, comprises dynamic model, cover half and die cavity, core, curved lever and exhaust outlet etc.
Injection mold is divided into two kinds on thermosetting plastic mould, thermoplastic plastic's mould according to shaping characteristic; Divide into biography mold, blow molding die, draw mould, thermoforming mould, hot-die (compression mould), injection mould etc. according to moulding process, wherein hot-die can be divided into excessive formula, half overflow formula, overflow three kinds of formulas again in the flash mode, and injection mould can be divided into two kinds of cold flowing mould channel, hot runner moulds again with running gate system; Can be divided into movable type, fixed two kinds by handling mode.But injection mold of the prior art all exists some problems and limitation, such as product when producing because the thimble skewness, be subjected to force unbalance, make the injection moulding failure; The demoulding is difficulty comparatively; Waste time and energy when whole die sinking and delivery, can't satisfy requirements of mass production; Security is not high etc.
Along with the progress of technology, up-to-date scientific and technological achievement has the 3D printer technology, belongs to a kind of of RP technique, but it is to use jointing materials such as powdery metal or plastics, by the multilayer printing type of layer upon layer, and the structure null object.Mould is made, industrial design is used for building model, is now just developing into the product manufacturing, forms " Direct Digital manufacturing ".Make three-dimensional object by the jointing material of printing from level to level.Present stage, three-dimensional printer was used to the perparation of specimen, and this technology can be used for jewelry, footwear, industrial design, building, engineering and construction (AEC), automobile, Aero-Space, dentistry and medical industries, education, GIS-Geographic Information System, civil engineering and many other fields.But there is comparatively obvious defects at present in this technology, and is also pitiably little such as price product quantity extremely expensive and that can print.
The utility model content
In order to overcome the deficiencies in the prior art, resolve prior art problems, remedy the existing deficiency of existing product in the market.
The utility model provides a kind of ball-type injection mold, the top cover of upper end, the cover half of top cover lower end, the understructure of dynamic model and bottom, wherein, cover half and dynamic model corresponding setting up and down, the inside, lower end of cover half is provided with a groove, be provided with embossing grooves in the groove, the inside, upper end of dynamic model is provided with moulded board, embossing grooves is relative with moulded board and establish, the moulded board lower end is connected with a plurality of oblique top pins, the oblique top pin is connected on the face needle plate by movable pulley, is provided with ball 14 near the exit in described glue injection channel 13, and the diameter of described ball 14 is slightly less than the internal diameter of glue injection channel 13.
Preferably, be provided with a plurality of mould posts between above-mentioned dynamic model and the understructure.
Preferably, base and outer base in above-mentioned understructure comprises.
Preferably, above-mentioned needle plate is fixed on the interior base by shank of a plurality of ends.
Preferably, the two ends of above-mentioned needle plate are provided with the locating piece that limits movable pulley limit of sports record position.
Preferably, the space that has relative motion between above-mentioned dynamic model and the oblique top pin.
The ball-type injection mold that the utility model provides is compared with traditional injection mold, the ball-type injection mold that the utility model provides arranges ball by the exit in glue injection channel, utilize the scroll actions of ball to realize moulding the stirring of liquid, thereby prevented from moulding the inhomogeneous of liquid liquid matter and the defective of the product quality that causes.
