Description
Technical field
The utility model relates to plastic processing technology, is specifically related to a kind of injection molding with curved lever.
Background technology
Plastic shaping is by the plastics of various form, as powder, pellet, solution and dispersion, makes the goods of required form or the process of blank.Plastic shaping is based on injection mo(u)lding, and injection mo(u)lding mainly adopts injection mold, and injection mold is a kind of instrument produced plastic products and commonly use.Injection mold divides into two kinds, thermosetting plastic mould, thermoplastic plastic's mould according to shaping characteristic; Divide into according to moulding process and pass mold, blow molding die, draw mould, thermoforming mould, hot-die, injection mould etc.Injection mould can be divided into again cold flowing mould channel, hot runner mould two kinds with running gate system.And due to the particular/special requirement of some plastic products structures, as convex with side, side is recessed, convex or screw thread etc., mould general at present often cannot meet processing request.
Utility model content
The utility model provides a kind of injection molding with curved lever, to meet the processing request with the convex plastic products in side.
This programme is as follows: the injection molding of band curved lever, comprise top clamping plate and gripper shoe, the left side of top clamping plate is fixed with core fixing plate, core is fixed in the left side of core fixing plate, the right side of gripper shoe is fixed with cavity plate, it is the dome with the ring-type of cavity plate one on the right side of cavity plate, the end face of dome can offset with the plate face of core fixing plate, the surface of core, it is injection die cavity between the right side of cavity plate and the inwall of dome, gripper shoe and dome are circumferentially arranged with multiple shaped bar with axial freedom, the tip inside of shaped bar extend in injection die cavity and also has groove thereon, along top clamping plate, core fixing plate, the axis middle part of core and cavity plate has installation through hole, install in through hole and be provided with runner lining, runner lining has runner hole.
This programme operation principle is as follows: after matched moulds, namely after the end face of dome and the plate face of core fixing plate offset and are close to, by the runner hole injection castable on runner lining, die sinking after injection-type intracavity forming, because the groove of plastic products because of shaped bar limits, can core be thrown off, and stay in the inwall of cavity plate and dome, then plastic products can be released cavity plate and dome by promoting shaped bar, completing the formed machining of plastic products.
The utility model is owing to being provided with multiple shaped bar in a mold, and the tip inside of shaped bar extend in injection die cavity and also has groove thereon, and therefore, the cylindrical of the plastic products that are shaped will be convex with side.
Further, the right side of gripper shoe is provided with the guide holder of ring-type, and the inwall of guide holder is provided with can along the guide plate of its movement, and the right-hand member of shaped bar is fixed on guide plate, guide plate is arranged with two push rods along the circumference of guide plate, and the left end of two push rods is arranged in gripper shoe and cavity plate.Push rod is for the discharging of the plastic products after being shaped.
Further, the longitudinal center line along guide plate, gripper shoe and cavity plate is equipped with charging ram.Charging ram for promote plastic products end face in the middle part of, fast plastic products are released the inwall of cavity plate and dome.
Further, runner hole is the tapered hole that ecto-entad aperture increases gradually, is more conducive to castable and fully flow to fast in injection die cavity during injection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
