Description

The device that pre-buried inserts covers is prevented on a kind of inlet manifold injection mold

Technical field

This utility model relates to inlet manifold injection mold field, is specifically related on a kind of inlet manifold injection mold the device preventing pre-buried inserts from covering.

Background technology

Inlet manifold is when injection mo(u)lding, it usually needs more pre-buried metal inserts, die sinking after injection completes, built-in metal inserts and the one-body molded taking-up of plastic air intake manifold.The most pre-buried metal insert is helicitic texture with holes, and two sections of built-in metal inserts are not likely to be plane, therefore in mould, nonplanar pre-buried inserts is not easy to fix, easily topple under the effect of pressure and raw material when injection or be subjected to displacement, causing the change in location of pre-buried inserts or the hole of built-in fitting to be melted raw material to enter, when causing die sinking, pre-buried inserts is capped, in order to solve above-mentioned technical problem, pre-buried inserts must be fixed, and not affect Shooting Technique.

Utility model content

For the problems referred to above, the purpose of this utility model provides a kind of device that when preventing plastic air intake manifold to be molded, pre-buried inserts covers, for fixing pre-buried inserts, prevent pre-buried inserts to be under pressure when injection mo(u)lding or the extruding of thermoplastic material and mobile or topple over, cause pre-buried inserts to cause thermoplastic materials to be covered in injection-molded finished middle depression.

nullThis utility model solves above-mentioned technical problem and be the technical scheme is that the device preventing pre-buried inserts from covering on a kind of inlet manifold injection mold，It is characterized in that，The some through holes being provided with including dynamic model、It is arranged on the pin in some through holes and several pre-buried inserts，The position of pin and pre-buried inserts sets according to the inlet manifold of different model，Some described pins are the two ends internal diameter metal bar more than stage casing internal diameter，Inserted in dynamic model by inside the mould of dynamic model，The lower end of some described pins is touched with ripple Lunella coronata wire connection，Described ripple Lunella coronata silk inserts from the outside of dynamic model，And threaded with dynamic model，Described ripple Lunella coronata silk controls moving up and down of pin by threads turn，The upper end of described pin and the lower end in contact of pre-buried inserts，And the upper end diameter of pin is more than the internal diameter of pre-buried inserts，External diameter less than pre-buried inserts，The upper end of described pre-buried inserts contacts with cover half，But do not fix with cover half and be connected；

Described pre-buried inserts is the pre-buried inserts of screw thread, the asymmetric setting in two ends of described pre-buried inserts, pin is arranged according to position and the angle of inclination of pre-buried inserts, if the one side of the most pre-buried inserts is inclined-plane, the pin matched is vertically arranged with this inclined-plane, it is ensured that there is active force between pin and pre-buried inserts, it is ensured that pin withstands pre-buried inserts, being allowed to be less likely to occur to move, the upper transverse plane of described pin completely attaches to the inclined-plane of pre-buried inserts；

The one side that described pre-buried inserts contacts with cover half is plane, is mutually extruded by cover half and pin, the position of fixing pre-buried inserts, it is ensured that during injection, pre-buried inserts will not move, and the flash caused covers the screwed hole of pre-buried inserts.

The utility model has the advantage of: this device increases some through holes on dynamic model; through hole arranges pin; being interacted by pin and cover half makes pre-buried inserts fix, and will not be subjected to displacement or topples over when injection, thus prevent pre-buried inserts to be covered by thermoplastic material；This utility model is simple and practical, transforms on the basis of existing equipment, reduces production cost, it is provided that the qualification rate of product.
