Description

Improve mould of moulding-die bubble

Technical Field

The utility model belongs to the technical field of dies, and particularly relates to a die for improving bubbles of a pressing die.

Background

In the compression molding process, as shown in the figure I, the mold is provided with a molding area, a cavity is formed in the molding area after the upper mold and the lower mold are closed, at the moment, the glue injection system starts injecting glue into the cavity, and because the mold is extremely high in sealing property, an exhaust groove is formed in the other side opposite to the glue injection side for injecting the glue, so that the gas in the cavity can be exhausted, and the glue can be completely filled in the cavity of the molding area.

Because part of residual gas in the process of flowing the glue to fill the cavity can be mixed with the glue initially entering the cavity to generate bubbles, the bubbles can be formed on the surface of the product or remain in the glue during production to cause the defect of the product

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides the die for improving the bubbles of the pressing die, and the gas in the cavity can be effectively discharged out of the cavity after the colloid flows into the forming area through the optimized design of the die, so that no bubbles are left in the colloid on the surface of the produced material, and the product yield is improved.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an improve mould of moulding-die bubble, includes the mould main part, the inside of mould main part is provided with the cavity shaping room that is used for the shaping, the one end of mould main part is provided with the air discharge duct, the injecting glue mouth has been seted up to the one end that the air discharge duct was kept away from to the mould main part, the heavy groove of exhausting has been seted up to the inside of air discharge duct.

As a preferable technical scheme of the die for improving the air bubbles of the pressing die, one end of the exhaust sinking groove, which is close to the forming chamber, is provided with an exhaust through hole communicated with the inside of the forming chamber.

In a preferred embodiment of the mold for improving air bubbles in the press mold according to the present invention, the air-discharging sinking groove is formed at an intermediate position between the upper and lower ends of the molding chamber.

As a preferable technical scheme of the die for improving the bubbles of the pressing die, a plurality of exhaust holes are formed in the forming chamber, are connected with one end of the exhaust sink groove, and are uniformly and symmetrically formed.

As a preferable technical scheme of the mould for improving the air bubbles of the press mould, the depth of the area of the exhaust sink groove is 0.5 mm.

Compared with the prior art, the utility model has the beneficial effects that: through digging a glue storage area deeply behind the mould exhaust duct, the glue that makes the mould can fully discharge the gas in the mould cavity smoothly and enter into the cavity originally and possibly mix the bubble also can be discharged and glue the storage area in the shaping in-process colloid, has solved the compression molding material and has had the bubble when the mould pressing, makes in the off-the-shelf colloid of material and the colloid surface can not have the bubble to persist, has promoted the product yield.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-2, the present invention provides the following technical solutions: the utility model provides an improve mould of moulding-die bubble, including mould main part 1, the inside of mould main part 1 is provided with and is used for fashioned cavity forming chamber 2, the one end of mould main part 1 is provided with air discharge duct 3, injecting glue mouth 4 has been seted up to the one end that air discharge duct 3 was kept away from to mould main part 1, exhaust heavy groove 5 has been seted up to the inside of air discharge duct 3, mould air discharge duct rear digs a storage glue region deeply in this embodiment, make the mould can be smoothly with the gaseous abundant discharge in the mould cavity and enter into the glue that the cavity probably mixed the bubble originally also can be discharged and store up the glue region in the forming process, it has the bubble to have solved the colloid when the mould pressing of compression molding material, make the off-the-shelf colloid in and the colloid surface of material can not have the bubble to persist, the product yield has been promoted.

Specifically, the end of the exhaust sink groove 5 close to the forming chamber 2 is provided with an exhaust through hole communicated with the inside of the forming chamber 2, and the exhaust sink groove 5 is arranged in the embodiment, so that the colloid can effectively discharge the gas in the cavity out of the cavity after flowing into the forming area, and no bubble is left in the colloid on the surface of the produced material, thereby improving the product yield.

Specifically, the exhaust sink 5 is provided at an intermediate position between the upper and lower ends of the molding chamber 2.

Specifically, the inside of the forming chamber 2 is connected with a plurality of exhaust holes at one end of the exhaust sink groove 5, and the exhaust holes are uniformly and symmetrically arranged.

Specifically, the depth of the region of the exhaust settling tank 5 is 0.5 mm.

The working principle and the using process of the utility model are as follows: the layout of the original mold molding area and the glue inlet vent groove is shown as a figure I, after the glue body in the original scheme is injected into the molding cavity, gas is discharged from the vent groove and a small amount of glue overflows from the vent groove; the novel mold is as shown in the figure II, and the colloid which enters the cavity initially and is possibly mixed with air can be smoothly discharged through the deeply dug exhaust groove by increasing the depth of the exhaust groove; the second point is that a glue storage area is dug in the deep digging area of the exhaust groove, so that the glue can be discharged more smoothly, and the problems of glue overflow and the like caused by the fact that the glue cannot be stored smoothly are avoided. The material colloid prepared by the method has no bubble residue inside and on the surface, and the influence of residual gas in the colloid on the external appearance and the internal reliability of a product is solved.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model.
