Description

A kind of automatic water gap cutting mould

Technical field

The utility model is related to die device technical field, and in particular to a kind of plastic mold for forming plastic cement product Tool.

Background technology

At present, the batch micro operations of many products are all completed by mould, and plastic mould is fairly common one kind Mould, mould is generally made up of upper mould/lower mould/core rod etc., or increases other accessories composition in mold periphery, passes through mould Sizing, to complete the shape molding of product.Formed product comes off after mould, it is necessary to by removing by hand into glue regrinding-material, no Workload can only be increased, production efficiency is reduced, increase production cost, and manually except the effect at the mouth of a river is bad, at the position of the mouth of a river Effect disunity is managed, some protrusions are more, some less, influence the quality of product again.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of simple in construction, efficiency high, mouth of a river high treating effect Automatic water gap cutting mould.

In order to solve the above technical problems, the utility model is adopted the following technical scheme that：A kind of automatic water gap cutting mould, including Master mold, core rod and forming cavity, core rod and forming cavity are located in master mold, and forming cavity is located at the both sides of core rod, have in core rod and use The forming cavity for the flow passage both sides circulated in material, provided with also passing through at feeding mouth, and thimble from runner in runner, it is special Levy and be：A cutter is respectively provided with the position that two forming cavities connect in runner, cutter is fixed on core rod；Have in the cutter Material mouth is crossed, material mouth is crossed and is located in runner；Blade part is formed with crossing above material mouth.

The porch size for crossing material mouth is more than exit size, and forming cavity is close in exit, in Flow of Goods and Materials mistake Cheng Zhonghui temporarily forms the accumulation portion of material in porch, but still can finally flow into forming cavity.

Further, the material mouth of crossing is square mouthful, and its blade part was located above the exit of material mouth, and blade part Down, in order to which regrinding-material is intactly cut by convenient.

Further, the bottom for crossing material mouth is horizontal flat face structure, and two sides are from the entrance for crossing material mouth Place is to exit inclined ramp structure inwardly, and top surface is then the ramp structure being downwardly inclined to exit, and the court of top surface has a down dip Tiltedly constitute blade part.

Further, the runner is "the" shape structure, and the cutter is arranged at the head and the tail two ends of runner and shaping The position that chamber connects.Such a structure of runner can keep uniform force, so as to reach more preferably mouth of a river processing Effect.

The course of work：Material enters air stream enter runner from feeding mouth, flows to the entrance behind tool position from material mouth excessively and enters into Ran Houcong The exit of opposite side flows into forming cavity and is molded.

After shaping cooling, the thimble of two thimbles and product position in runner is acted together, by the water in product and runner Mouth expects jack-up together.During jack-up, regrinding-material is cut off by the blade part of cutter, so as to obtain without further cutting off regrinding-material Product.

The utility model installs cutter by the position connected with forming cavity in runner, product in ejection, regrinding-material It can be automatically cut off by cutter, and it is smooth, attractive in appearance after the cut-out of mouth of a river position, so as to lift the quality of product；Further, since regrinding-material is Automatically cut off when product is ejected, without artificial water dividing gap, so as to drastically increase production efficiency.

In figure, 1 is product, and 2 be cutter, and 21 be material mouth, and 22 be blade part, and 3 be that at thimble, 4 be core rod, and 5 be female Mould, 6 be runner, and 7 be feeding mouth, and 8 be accumulation portion.

Embodiment

In the present embodiment, the automatic water gap cutting mould, including master mold 5, core rod 4 and forming cavity（It is not shown）, core rod 4 and Forming cavity is located in master mold 5, and forming cavity is located at the both sides of core rod 4, and there is the runner 6 for being used for material circulation to connect in core rod 4 The forming cavity of both sides, is provided with feeding mouth 7 in runner 6, and 3 also passes through at thimble from runner 6, in runner 6 and two forming cavity phases The position connect is respectively provided with a cutter 2, and cutter 2 is fixed on core rod；There is material mouth 21 in the cutter 2, cross material mouth 21 and be located at In runner 6；Blade part 22 is formed with the top for crossing material mouth 21.

The porch size for crossing material mouth 21 is more than exit size, and forming cavity is close in exit, in Flow of Goods and Materials process It is middle that the accumulation portion 8 of material can be temporarily formed in porch, but still can finally flow into forming cavity, production process will not be caused Influence.

It is square mouthful to cross material mouth 21, and its blade part 22 was located above the exit of material mouth, and blade part 22 is down, with It is easy to regrinding-material intactly to be cut by convenient.

The bottom for crossing material mouth 21 is horizontal flat face structure, and two sides are from the porch of material mouth excessively to exit court Tilted ramp structure, top surface is then the ramp structure that is downwardly inclined to exit, and top surface is downwardly inclined composition blade part 22。

Runner 6 is "the" shape structure, and the cutter 2 is arranged on the position connected at the head and the tail two ends of runner 6 with forming cavity Put.Such a structure of runner 6 can keep uniform force, so as to reach more preferably mouth of a river treatment effect.

The course of work：Material enters air stream enter runner 6 from feeding mouth 7, flows to the entrance behind tool position from material mouth 21 excessively and enters into so Flow into forming cavity and be molded from the exit of opposite side afterwards.After shaping cooling, the thimble of two thimbles and product position in runner 6 Act together, by the regrinding-material in product 3 and runner 6 together jack-up.During jack-up, regrinding-material is by the blade part 22 of cutter 2 Cut-out, so as to obtain the product without further cutting off regrinding-material.

The utility model is described in detail above, it is described above, only the preferred embodiment of the utility model and , it is when the utility model practical range can not be limited, i.e., all to make equivalent changes and modifications according to the application scope, it all should still belong to this In utility model covering scope.
