Description
Technical field
What the utility model related to a kind of injection mold enters plastic structure, and what particularly relate to a kind of injection mold from slide block charging enters plastic structure, particularly a kind of silicon rubber injection mold from slide block charging enter plastic structure.
Background technology
In injection mold field, adopt in submarine type glue feeding the structure generally used as shown in Figure 1, comprise front template 1, rear pattern plate 3, mother module core 4 and rear cavity 7, runner 2 is provided with in described mother module core 4, be provided with product die cavity 5 between described mother module core 4 and rear cavity 7, described front template 1 is provided with charging aperture 6, and described charging aperture 6 is connected with runner 2, sizing material enters from charging aperture 6, enters into product die cavity 5 complete injecting glue by runner 2; Then, after front template 1 being separated die sinking with rear pattern plate 3, runner is directly broken by the material pin that draws of rear pattern plate 3, and the mouth of a river is deviate from, and this structure is applied to deviating from of most product and runner.
Above-mentioned this die glue inlet structure mode can only be applicable to the product that most of product is comparatively large, shape of product is simple or shape requirement is not high, this type product material constraints used is the good plastic material of toughness, and for the very little flexible glue product of weight, if weight is at the product of about 0.01g, especially comparatively complicated for structure, as flexible glue bag ebonite series products, because its appearance requirement is very high and cannot enter glue from front mould die joint, above-mentioned enter plastic structure then can not use.
Utility model content
For above-mentioned technical problem, the invention provides a kind of injection mold from slide block charging and enter plastic structure, solve above-mentioned very light in weight or baroque product cannot enter glue problem from front mould die joint.
To this, the technical solution of the utility model is:
A kind of injection mold from slide block charging enters plastic structure, comprise front template, rear pattern plate, front mould jade, slide block and shovel, described front template is provided with charging aperture, product die cavity is provided with between described front mould jade and rear pattern plate, slide block is provided with between described front template and rear pattern plate, the front end of described slide block is connected with front mould jade, and the rear end of described slide block is connected with shovel; Be provided with in described front mould jade into solation road, described slide block is provided with slide block runner, and one end of described slide block runner is connected with described charging aperture, the other end of described slide block runner with described enter solation road be connected; Described enter the angle of solation road and horizontal plane be 1 ~ 80 degree.
Adopt this technical scheme, after forward and backward template is opened, shovel base moving belt movable slider is simultaneously back to setpoint distance, and the sizing material that will enter in solation road and slide block runner while slide block retreats pulls out slide block, sizing material and product in runner is caused to come off, simultaneously because the retrogressing of slide block also makes product deviate from.
As further improvement of the utility model, described shovel is fixedly connected with described front template.
Adopt this technical scheme, after formed product OK, forward and backward template is opened, the all mechanisms of rear mold and product are simultaneously back to setpoint distance, utilize the shovel base band movable slider fixing with front template simultaneously back to setpoint distance, the sizing material pull-out slide block entered in solation road and slide block runner while slide block retreats, sizing material and product in runner is caused to come off, simultaneously because the retrogressing of slide block also makes product deviate from.
As further improvement of the utility model, described in enter solation road and horizontal plane angle be 20 ~ 60 degree.Adopt this technical scheme, be convenient to charging faster, be also convenient to the pull-out of sizing material simultaneously.
As further improvement of the utility model, the volume of described slide block runner is 4 ~ 6 times of the volume of described product die cavity.Adopt this technical scheme, the interior sizing material that can hold of described slide block runner be described product die cavity content receive 4 ~ 6 times of sizing material, solve the too little and injection difficult problem that causes of product weight by the weight of increase stub bar like this.
As further improvement of the utility model, described slide block is also provided with the weightening finish die cavity be connected with described slide block runner.Adopting this technical scheme, solving the too little and injection difficult problem that causes of product weight by increasing the weight of stub bar.
As further improvement of the utility model, described in the angle of described slide block runner and horizontal plane is less than, enter the angle of solation road and horizontal plane.Adopt this technical scheme, be convenient to the pull-out of sizing material better.
Compared with prior art, the beneficial effects of the utility model are:
First, the utility model mainly be have employed to be transferred in front cavity by slide block runner and enters glue, the stub bar produced be that certain gradient connects, and the characteristic due to silica gel material is extremely flexible, extremely softness, even if there is back-off, also can take off by force, so during die sinking, all stub bars all can be pulled out, so both shortening the molding cycle of mould, also solving the too little and injection difficult problem that causes of product weight by increasing stub bar weight.
The second, of the present utility model enter plastic structure successfully solve the production of this cover encapsulation die, while the guarantee product smooth demoulding, also ensure that the smooth demoulding of runner, well control injection amount simultaneously, make mould can stablize lasting production.
