Description

The axle sleeve mould

Technical field

The utility model relates to a kind of axle sleeve mould that is used to produce plastic sleeve.

Background technology

At present, the cast gate that is used to produce the axle sleeve mould of plastic sleeve generally is positioned at the die cavity wall that mould is used for the shaped article outer surface, and like this, the outer surface of product just has the vestige of cast gate, and then influences the outward appearance of product; And the product that injection moulding is come out generally needs artificial the pruning, will expect that handle shears off from product, so just greatly reduces production efficiency.

The utility model content

The technical problems to be solved in the utility model is, the vestige that a kind of product external surfaces do not have cast gate, the axle sleeve mould that need not manually to prune product are provided.

The technical solution of the utility model is; the utility model comprises quiet mould, dynamic model and is used to make up that the core of die cavity and runner, quiet model cavity are inserted, the movable model cavity insert; described core and dynamic model are slidingly connected; described quiet model cavity is inserted and is fixedly mounted on the quiet mould; described movable model cavity insert is fixedly mounted on the dynamic model; described movable model cavity insert is provided with the through hole for the push rod activity of dynamic model; described core is provided with cast gate; one end of this cast gate communicates with runner, and the other end of this cast gate communicates with die cavity.

After adopting said structure, the utility model compared with prior art, have the following advantages: the utility model axle sleeve mould is provided with cast gate on described core, one end of this cast gate communicates with runner, the other end of described cast gate communicates with die cavity, that is to say, described cast gate is positioned at product inwall place, like this, just fundamentally solved the problem that product external surfaces leaves the vestige of cast gate; And the slip of described core can be cut off the material handle from the product inwall, so just need not manually to prune product, realizes that the material handle separates from product automatically, has improved production efficiency.

As improvement, it also comprises by Angle Pin, latch segment, slide block, be used for the Angle Pin mechanism that limited block that anti-limited slip block skids off is formed; Described Angle Pin and latch segment are fixedly mounted on the quiet mould; Described slide block is connected with core is removable, and described core and dynamic model are slidingly connected and are meant that integral body and dynamic model that described slide block and core connect into are slidingly connected; Described limited block is fixedly mounted on the dynamic model; Described Angle Pin mechanism is existing general technology, and the action by described Angle Pin mechanism can realize moving of described core very easily, like this, just do not need to have simplified the structure of the utility model axle sleeve mould, reduced cost for described core mobile is provided with new travel mechanism.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

The utility model axle sleeve mould, it comprises quiet mould 1, dynamic model 2 and is used to make up that the core 5 of die cavity 3 and runner 4, quiet model cavity insert 6, movable model cavity insert 7, described core 5 is slidingly connected with dynamic model 2, described quiet model cavity is inserted and 6 is fixedly mounted on the quiet mould 1, described movable model cavity insert 7 is fixedly mounted on the dynamic model 2, described movable model cavity insert 7 is provided with the through hole for push rod 8 activities of dynamic model 2., described core 5 is provided with cast gate 9, one end of this cast gate 9 communicates with runner 4, and the other end of this cast gate 9 communicates with die cavity 3.Concrete structure is shown in Fig. 1 or 2.The structure of concrete structure and part dynamic model 2 of also having drawn quiet mould 1 among the figure, comprise centring ring 1.1, quiet mould fixed head 1.2, quiet die-cushion plate 1.3, runner lining 1.4, dynamic model backing plate 2.1, described centring ring 1.1, quiet mould fixed head 1.2, quiet die-cushion plate 1.3, runner lining 1.4, dynamic model backing plate 2.1 are prior art, annexation also is existing annexation, does not add and gives unnecessary details.

It also comprises by Angle Pin 10, latch segment 11, slide block 12, be used for the Angle Pin mechanism that limited block 13 that anti-limited slip block 12 skids off is formed; Described Angle Pin 10 and latch segment 11 are fixedly mounted on the quiet mould 1; Described

slide block

12 and 5 removable connections of core, described core 5 are slidingly connected with dynamic model 2 and are meant that described slide block 12 and integral body and the dynamic model 2 that core 5 connects into are slidingly connected; Described limited block 13 is fixedly mounted on the dynamic model 2.Concrete structure is shown in Fig. 1 or 2.

When using the utility model axle sleeve mould, at first quiet mould 1 and dynamic model 2 are fixed on the injection machine by existing connected mode; As Fig. 1, the utility model axle sleeve mould is under the matched moulds state, and injection machine carries out injection moulding and pressurize and cooling; As Fig. 2, the utility model axle sleeve mould is under the die opening state, described material handle 14 and product 15 are positioned on the dynamic model 2, at this moment, described slide block 12 segment distance that under the promotion of Angle Pin 10, outwards slided, like this, described core 5 just will expect that with moving of slide block 12 handle 14 from product 15 separately, and,, can not be stuck in the cast gate 9 so material handle 14 will skid off from cast gate 9 because plastics have better elastic; Under the position-limiting action of limited block 13, described slide block 12 just can not skid off from dynamic model 2; Then, described push rod 8 will expect that handle 14 and product 15 eject from dynamic model 2 under the drive of injection machine thimble, make material handle 14 and product 15 break away from mould.After finishing above-mentioned steps, described push rod 8 resets, then, the injection machine matched moulds, under the effect of described Angle Pin mechanism, described slide block 12 and core 5 reset, after the injection machine matched moulds finishes, repeat above-mentioned step except that quiet mould 1 and dynamic model 2 are installed, just can carry out the production of next circulation.
