Description

A kind of injection mold

Technical field

The utility model relates to a kind of injection mold.

Background technology

When design injection mold, if when master mold has barb, also accordingly there is barb the same with male model, need to have 2 ejector retainner plates to coordinate oblique top to take off barb.The principle of this structure is: when the die sinking of male and female die, master mold needle plate due to excellent power collagen because of, start to move down, in master mold, oblique top also moves thereupon simultaneously, until barb is wherein also provided with the guide pillar that runs through upper bolster, stripper plate, upper ejector retainner plate, lower ejector retainner plate and caster, guide pillar is responsible for the needle plate that leads, prevent oblique top offset, card breaks.

This type of solves barb mode need to, at 2 blocks of plates of the inner increase of template, go up ejector retainner plate and lower ejector retainner plate, so corresponding mould bases just needs increasing, waste material and resource.

Utility model content

The utility model is intended at least solve one of technical problem existing in prior art.

For addressing the above problem, the utility model proposes a kind of injection mold, comprising: upper mounted plate; Caster, described caster is located at the below of fixed plate; Mother module core and male die core, described mother module core is located at the below of described caster, and described male die core is located at the below of described mother module core, forms the die cavity for the treatment of injecting products between mother module core and male die core; Oblique top, described oblique top is positioned at mother module core, and its upper end connects tilted footstock, and tilted footstock is connected with upper mounted plate through described caster, and match with master mold barb position in its lower end; In described oblique top, be also provided with limiting stand; And spring, described spring is located between fixed plate and caster.

According to injection mold of the present utility model, and false three plates of this structure (false three plates: principle is similar with three template dies, but only need twice of die sinking just passable, the reason that needs die sinking is to solve product barb, and three template dies are die sinking three times, be to solve the mouth of a river to drop), by spring and oblique top, before the die sinking of male and female die, due to the effect of spring, first die sinking between upper mounted plate and caster, when die sinking, upper fixed seat pulls oblique top motion by tilted footstock, depart from from barb, thereby solved master mold barb problem.Therefore, the utlity model has easy for installation, processing is simple, master mold barb mode is ingenious, demand space is little, the feature cutting the waste.

In addition, also there is following additional technical feature according to injection mold of the present utility model:

Preferably, described tilted footstock is connected with fixed plate by bolt.

Preferably, the model of described bolt is M6*30.

Preferably, the upper end of described oblique top and the upper surface of mother module core are concordant.

Preferably, described limiting stand comprises upper limit platform and lower limit platform.

Preferably, the lower surface of described caster is provided with stopper slot, and this stopper slot is corresponding with the upper limit platform of described oblique top.

Preferably, between fixed plate and caster, be provided with pull bar.

Preferably, described spring housing is connected on described pull bar.

Additional aspect of the present utility model and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present utility model.
