Abstract
The invention discloses a membrane suction mechanism. The membrane suction mechanism is characterized by comprising a plurality of air suction holes arranged in a female template, one end of each air suction hole extends from the inside of the female template to be connected with an external air extractor, and the other end of each air suction hole reaches the top face of a female die kernel in the female template and is communicated with an air suction trough arranged on the top face of the female die kernel; a circle of air suction troughs are arranged in the top face and the bottom face of the female die kernel along the periphery of the female die kernel, and the air suction troughs on the top face and the bottom face of the female die kernel are communicated by a plurality of through holes. According to the membrane suction mechanism provided by the invention, in the injection molding process, the air in a cavity in the die kernel is constantly exhausted through the air suction holes and the air suction troughs to form a negative pressure environment in the cavity, and a membrane in the cavity is kept in an absorbed flat state all the time, so that the decorative pattern on the membrane is kept unchanged and the membrane pressing effect is improved.
Description
Technical field
The present invention relates to a kind of film adsorption mechanism, belong to technical field of mold.
Background technology
At present, the shell of many notebooks all has decorative pattern, for this notebook computer shell that has decorative pattern; When adopting mold injection molding; Need in die, be provided with one have a decorative pattern film, and then injection moulding, the decorative pattern on the film is on the notebook computer shell with regard to the product that is transferred to injection mo(u)lding like this.Yet because film is thinner, yielding or displacement is smooth if film can not keep in injection moulding process, can make the decorative pattern distortion that is transferred on the notebook computer shell, influences the press mold effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of film adsorption mechanism, and in injection moulding process, it is smooth that film is remained, thereby makes decorative pattern on the film shape that remains unchanged, and improves the press mold effect.
For solving the problems of the technologies described above; The present invention provides a kind of film adsorption mechanism; It is characterized in that, comprise a plurality of aspirating holes that are arranged in the caster, aspirating hole one end extends to the air extractor of outside in the caster and is connected; The aspirating hole other end arrives at the end face of the mother module core in the caster, connects with the groove of bleeding set on the mother module core end face; The one circle groove of bleeding is being set around the mother module core respectively on the end face of mother module core, the bottom surface, and end face is connected through a plurality of through holes with the groove of bleeding on the bottom surface.
The groove of bleeding on the bottom surface of said mother module core is pressed close to the film in the die cavity mutually.
Mother module core and the male model benevolence of said die cavity after by matched moulds forms.
When said air extractor was bled, said film was adsorbed on the bottom surface that is affixed on said mother module core.
The beneficial effect that the present invention reached:
Film adsorption mechanism of the present invention in injection moulding process, is constantly bled to the die cavity in the die through the aspirating hole and the groove of bleeding; Make the environment that forms negative pressure in the die cavity; Make the film in the die cavity remain the formation state that is adsorbed, thereby make decorative pattern on the film shape that remains unchanged, improve the press mold effect.
Description of drawings
Fig. 1 is a film adsorption mechanism sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1; Film adsorption mechanism of the present invention comprises a plurality of aspirating holes 2 that are arranged in the caster 1; Aspirating hole 2 one ends 21 extend in the caster 1 with outside air extractor and are connected; Aspirating hole 2 other ends 22 arrive at the end face 31 of the mother module core 3 in the caster 1, connect with the groove 41 of bleeding set on the mother module core end face 31.The one circle groove 41,42 of bleeding is being set around the mother module core respectively on the end face 31 of mother module core, the bottom surface 32, and end face 31 is connected through a plurality of through holes 5 with the groove 41,42 of bleeding on the bottom surface 32.The groove 42 of bleeding on the bottom surface 32 of mother module core is pressed close to the film 7 in the die cavity 6 mutually.Like this; When air extractor is bled; The groove 42 of bleeding of the groove 41 of bleeding that will be through aspirating hole 2, mother module core end face 31, through hole 5, mother module core bottom surface 32 is extracted the gases in the die cavity 6 out; Make to form negative pressure in the die cavity 6, make the film 7 that is provided with in the die cavity be adsorbed to the closing-type inner cavity surface above, can keep smooth indeformable.
Die cavity 6 is cavitys of a mother module core 3 and a relative closure that is arranged at the male model benevolence 9 matched moulds formation in the male model plate 8.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
