Description

A kind of connector low pressure mold

Technical field

The utility model relates to technical field of mold, especially a kind of connector low pressure mold.

Background technique

The advantages that stock utilization possessed by low pressure casting method is high, note soup easy to accomplish automates, but most low pressure The molten soup of mold raw material enters the speed in stalk and unhappy, then needs to expend longer time and ventilate；And it is based on mould Having the structure limitation of itself, when needing to be removed from the molds after formed product, then needing to carry out mold to remove could take out, It also needs to reinstall when mold reuses, this undoubtedly increases procedure of processing, affects to the efficiency of production； Therefore, it is necessary to which ground improves the structure of low pressure mold.

Utility model content

The utility model is insufficient in view of the above technology, provide it is a kind of can make to be passed into the molten soup of raw material by inclined venthole Interior gas has certain directionality, is easier the molten soup of raw material rise in stalk into forming cavity, and do not need Mold is integrally removed i.e. the low pressure mold that can be taken off the connector of casting and forming.

In order to achieve the above objectives, the utility model is achieved through the following technical solutions:

A kind of connector low pressure mold, including die holder, side form and backform, the side form cooperation is the two of die holder upper surface Side, the backform are arranged in the top of side form, the molten soup chamber for storing raw material, the top of the die holder are equipped in the die holder Center, which is run through to have, extends to the intracavitary stalk of molten soup, is provided with the first mold core on the outside of the top section of the stalk, described It is equipped with the second mold core between first mold core and side form, blow vent is provided between the backform and side form, the backform is by setting The top that the slipping mechanism in side form two sides is connected to side form is set, the inside of first mold core, the second mold core and backform is constituted Space be forming cavity, the side form bottom outside offers the venthole being connected to the top outer of die holder.

Further, the slot being connected to, the inside of the slot are offered at the top of the bottom outside of the side form and die holder End is a cavity, and the slot is built-in to be inserted with thimble, and the inner end of the thimble of position in the cavity is equipped with half spherical shape The first convex block, two side bottoms of first mold core are equipped with a second hemispherical convex block.

Further, the slipping mechanism includes sliding column, stud and nut, the backform by two plates backform formwork It is made up of, opens up in the backform formwork by first sliding groove, the sliding the cooperation between the groove and third convex block at middle part Column cooperates in first sliding groove, and the stud welding is between two pieces of support plates on sliding column and cooperates in the first sliding groove Interior, the upper and lower ends of the stud cooperate by nut, and second sliding slot, the bottom of the sliding column are offered on the outside of the side form Portion is equipped with sliding block, and the sliding column is by the mating connection between sliding block and second sliding slot on side form.

Further, the venthole is gradually opened up in height from outside to inside.

The utility model has the following beneficial effects:

It can make the gas being passed into the molten soup of raw material with certain directionality by inclined venthole, make the molten soup of raw material It is easier to rise in stalk and enter in forming cavity；Connector after molding is jacked up by thimble and makes to push up by slipping mechanism Mould is opened, and the connector of casting and forming can be taken out in the case where not needing mold and integrally being removed, and easy to operate.
