Abstract

The utility model discloses a pouring die with replaceable inserts, which is characterized by comprising an upper die and a lower die, wherein the upper die comprises an upper outer die and an upper insert fixedly connected to the inner side of the upper outer die; the lower die comprises a lower outer die and a lower insert fixedly connected to the inner side of the lower outer die; after the upper die and the lower die are oppositely closed, a pouring cavity is formed by the upper insert and the lower insert; the upper die is provided with a pouring passage for enabling poured liquid to flow to the pouring cavity; and the distance from an outlet of the pouring passage to the lower insert is the shortest. The pouring die has the benefits that the inserts can be separated from the outer dies, the change of the cavity of the pouring die can be easily realized by replacing the upper insert or the lower insert without reopening the whole die, and the pouring die not only saves time and labor and reduces cost investment, but also can be well suitable for diversified production; the distance from the outlet of the pouring passage to the lower insert is the shortest so as to ensure the highest integrity of the front side of an LED mirror plane, so that an excellent diffusing effect of the LED mirror plane is ensured.

Description

The perfusion mould of replaceable inserts

Technical field

The utility model relates to a kind of perfusion mould, is specifically related to a kind of for the perfusion mould LED moulding, replaceable inserts.

Background technology

LED is as a kind of novel illumination light source, and its advantage of giving prominence to energy-saving and environmental protection, luminous efficiency is high, the life-span is long etc. is applied in various occasions, such as the street lamp that adopts great power LED as light source, wall lamp etc. more and more widely.

The LED moulding need to be by filling with the mould mould pressing technology; normally directly weld or be adhesive in led chip on heat conductive insulating substrate or the ordinary circuit board; then cover one deck protection glue at led chip; for making its luminous efficiency high; protection glue need to form spherical lens on the surface of led chip, is called LED eyeglass plastotype, and LED eyeglass plastotype is realized by means of the perfusion mould; so moulding has important effect to the perfusion mould to LED.And existing perfusion mould has certain defective, for example: the design underaction, the moulding of a kind of LED eyeglass of every replacing just needs to reopen a secondary mould, and this has not only expended a large amount of time, has also greatly increased the input of cost.

The utility model content

Be to solve the deficiencies in the prior art, the purpose of this utility model be to provide a kind of be easy to change moulding, time saving and energy saving, reduce the perfusion mould that cost drops into simultaneously, this perfusion mould has removable inserts, can well adapt to variation production.

In order to realize above-mentioned target, the utility model adopts following technical scheme:

The perfusion mould of replaceable inserts, it is characterized in that, comprise mold, bed die, mold comprises: upper external mold, be fixedly connected on the upper inserts with upper impression of external mold inboard, bed die comprises: lower external mold, be fixedly connected on the lower inserts with lower impressions of lower external mold inboard; After aforementioned mold and bed die were involutory, upper inserts and lower inserts formed the perfusion die cavity, and aforementioned mold has the perfusion channel that flows to the perfusion die cavity for perfusion liquid.

The perfusion mould of aforesaid replaceable inserts is characterized in that, aforementioned upper external mold and upper inserts are formed with internal thread hole, and upper inserts is fixedly connected on the upper external mold by screw.

The perfusion mould of aforesaid replaceable inserts is characterized in that, aforementioned lower external mold and lower inserts are formed with internal thread hole, and lower inserts is fixedly connected on the lower external mold by screw.

The perfusion mould of aforesaid replaceable inserts is characterized in that, the port of export of aforementioned perfusion channel is arranged on the near lower inserts end of the upper impression of inserts, and is the shortest with the distance of lower inserts.

Usefulness of the present utility model is: upper inserts and separable, the lower inserts of upper external mold and lower external mold are separable, by replacing with inserts or lower inserts or replacing with simultaneously inserts and lower inserts, can be easy to realize pouring into the change of mold cavity, thereby reach the purpose of changing the moulding of LED eyeglass, need not to reopen a whole set of mould, not only time saving and energy saving, reduction cost drops into, and more can well adapt to variation and produce; The port of export of perfusion channel is arranged on the near lower inserts end of the upper impression of inserts, and is the shortest with the distance of lower inserts, guaranteed the positive farthest integrality of LED minute surface, thereby the light-dispersing effect that has guaranteed the LED minute surface is good.

Description of drawings

Fig. 1 is the assembled state structural representation of perfusion mould of the present utility model;

Fig. 2 is the decomposing state structural representation of perfusion mould of the present utility model;

The upper external mold of the implication of Reference numeral: 1-among the figure, the upper inserts of 2-, 2 '-upper inserts, 3-upper impression, external mold under the 4-, inserts under the 5-, 6-lower impressions, 7-perfusion channel, 8-screw, the 9-port of export.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.

See figures.1.and.2, the perfusion mould of replaceable inserts of the present utility model comprises mold, bed die.Mold comprises: upper external mold 1, upper inserts 2; Upper inserts 2 is fixedly connected on external mold 1 inboard, and has upper impression 3, and upper impression 3 is used for LED eyeglass plasticity.Bed die comprises: lower external mold 4, lower inserts 5; Lower inserts 5 is fixedly connected on lower external mold 4 inboards, and also has die cavity, is lower impressions 6.After mold and bed die were involutory, upper impression 3 was also namely involutory with lower impressions 6, thereby formed the perfusion die cavity.Upper external mold 1 all has perfusion channel 7 with upper inserts 2, perfusion liquid through perfusion channel 7 by the outer flow of mould to the perfusion die cavity, finish perfusion.

As a kind of preferred scheme, upper external mold 1 is formed with internal thread hole (not shown) with upper inserts 2, and upper inserts 2 is fixedly connected on the upper external mold 1 by screw 8.When needs change the moulding of LED eyeglass, only need to take off upper inserts 2 from upper external mold 1, and change upper inserts 2 with required moulding ' get final product, and upper external mold 1 keeps, greatly saved the required time of again die sinking, not only time saving and energy saving, reduction cost drops into, and more can well adapt to variation and produce.

As a kind of preferred scheme, lower external mold 4 is formed with internal thread hole (not shown) with lower inserts 5, and lower inserts 5 is fixedly connected on the lower external mold 4 by screw 8.Lower inserts 5 also can be changed, and need not again to make bed die, operates more quick and easy.

As a kind of preferred scheme, the port of export 9 of perfusion channel 7 is arranged near lower inserts 5 one ends of the upper impression 3 of inserts 2, and is the shortest with the distance of lower inserts 5.In the LED eyeglass plastotype process, perfusion liquid in the perfusion channel 7 is also thereupon fixed-type, be called removing residual glue at this, and removing residual glue need to cut away in the operation of back, the place that removing residual glue is connected with the LED eyeglass approaches lower inserts 5 one ends, the shortest with the distance of lower inserts 5, that is to say that removing residual glue is in the root of LED eyeglass, not only convenient excision, and the cut channel position is relatively low, has guaranteed the positive farthest integrality of LED minute surface, can not exert an influence to the light-dispersing effect of LED minute surface.

Need to prove that above-described embodiment does not limit the utility model in any form, all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
