Abstract
The utility model discloses an injection mold with an intramode automatic nozzle material cutting structure, which comprises a male mold and a female mold correspondingly arranged with the male mold. A male mold core is arranged on the male mold, a female mold core is arranged on the female mold, the male mold core and the female mold core are correspondingly arranged, a cutting pouring gate knife edge insert, a passageway, a pouring gate thimble and a sprue puller are arranged on the male mold, a balanced ejection material cavity is arranged on the passageway, the passageway is arranged at the upper end of the cutting pouring gate knife edge insert, the upper portion of the pouring gate thimble penetrates in the male mold core, and when the injection mold is opened, the pouring gate thimble and the sprue puller are synchronously ejected out. The injection mold with the intramode automatic nozzle material cutting structure can complete cutting of nozzle through ejection of an injection molding machine, improves production efficiency and saves labor cost.
Description
Technical field
The utility model relates to a kind of injection mold, specifically a kind of injection mold with automatic water dividing gap material structure in the mould.
Background technology
Traditional injection mold of water dividing gap material structure automatically that has in the mould that is used to make electronic products such as mobile phone, network interface card, normally before die sinking with the product gate cutting.Since be before die sinking with the gate cutting of product, therefore, need carry out some special settings to injection machine, guarantee that the injection moulding function is accomplished to cut off action that cut off the unnecessary mouth of a river material of product, the outward appearance of assurance product is neat before die sinking.
The mode at a kind of in addition injection mold mould internal cutting off mouth of a river is to realize at different ejection strokes through thimble; Two thimbles that ejection stroke is different are set on the injection mold dynamic model; A thimble is used to eject the product mouth of a river; Another thimble is used to cut off the cast gate of injecting products, under the effect that ejects of injection machine, be used to cut off cast gate thimble eject distance greater than the thimble that is used to eject the mouth of a river.
Traditional mode of operation needs two operations, labor intensive, time, cause the low of production efficiency, and the undercut construction of injection mold is comparatively complicated, makes that the processing cost of mould is higher.
Summary of the invention
The technical problem that the utility model will solve provides a kind of injection mold with automatic water dividing gap material structure in the mould, can accomplish the mouth of a river when injection moulding ejects and cut off, and enhances productivity, and practices thrift cost of labor.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
Have in the mould injection mold of water dividing gap material structure automatically, comprise male model and with the master mold of the corresponding setting of male model, male model is provided with male model benevolence; Master mold is provided with mother module core, the corresponding setting of male model benevolence with mother module core, and male model is provided with cuts cast gate edge of a knife mold insert, runner, cast gate thimble and sprue puller; Runner is provided with balance and ejects the material chamber, and runner is located at and is cut cast gate edge of a knife mold insert upper end, and cast gate thimble top is pierced in the male model benevolence; During the injection mold die sinking, cast gate thimble and sprue puller eject synchronously.
Said balance ejects the material chamber and is opened in the flow passage side below.
The end of said sprue puller is irregularly shaped.
The utility model is the cast gate material to be cut off when after die sinking, ejecting through thimble; Cast gate is saved artificial time and the manpower of cutting material in artificial cut smooth of product appearance, avoids the generation of product burr; It is simple to operate; Easy to use, reached the purpose of the residual stub bar of fast shut-off, improved the quality and the production efficiency of product.
Description of drawings
Accompanying drawing 1 is for the utlity model has the injection mold cross-sectional view of automatic water dividing gap material structure in the mould.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.
Shown in accompanying drawing 1; The utility model has disclosed a kind of injection mold of water dividing gap material structure automatically that has in the mould, male model and with the master mold of the corresponding setting of male model, male model is provided with male model benevolence 1; Master mold is provided with mother module core 2; Male model benevolence 1 and mother module core 2 corresponding settings are provided with in the male model benevolence 1 and cut cast gate edge of a knife mold insert 3, runner 4, cast gate thimble 5 and sprue puller 6, and runner 4 is located at and is cut cast gate edge of a knife mold insert 3 upper ends; Cast gate thimble 5 tops are pierced in the male model benevolence 1, and sprue puller 6 pierces in the male model benevolence 1 and upper end and runner 4 attachings.Runner 4 is provided with balance and ejects material chamber 7, and this balance ejects expects that chamber 7 produces a balance and ejects stub bar in injection moulding process.During the injection mold die sinking, male model benevolence 1 is separated with mother module core 2, ejects synchronously at the effect submarine gate thimble 5 and the sprue puller 6 of injection machine push rod.
The injection mold that the utlity model has automatic water dividing gap material structure in the mould is when ejecting product; Effect submarine gate thimble 5 and sprue puller 6 through the injection machine push rod eject synchronously; Balance ejects stub bar and plays restriction power; Make the mouth of a river material of sprue puller 6 cast gate one side when ejecting have cut-out power upwards, and under the effect of cast gate thimble 5, cut off smoothly; An operation can be accomplished the cut-out that expect at the mouth of a river when injection moulding ejected, and realized automation, to raise the efficiency, practiced thrift cost of labor.
The foregoing description is the principle and the effect thereof of illustrative the utility model only; And the embodiment of part utilization; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model claim.
