Abstract
The utility model discloses a flow backward three-plate mold for injection molding. The flow backward three-plate mold comprises a male mold side second fixing plate, a stripping plate, a male mold side first fixing plate, a male mold, a female mold and a female mold fixing plate, wherein the female mold is arranged on the male mold; the female mold fixing plate is arranged on the female mold; the male mold side second fixing plate, the stripping plate and the male mold second fixing plate are sequentially arranged on the lower side of the male mold; a glue inlet is formed in a male mold side; and a glue material enters a cavity through a male mold core on a male mold plate. According to the flow backward three-plate mold for injection molding, positions of the male mold and the female mold are interchanged; the glue material enters the cavity through the glue inlet formed in the male mold side from the male mold core; and the shortcoming that the appearance of a product is influenced by a reason that the glue material enters the cavity through a glue inlet formed in a female mold side from a female mold core is overcome.
Description
Technical field
The utility model relates to a kind of injection mold, relates in particular to a kind of three template dies that pour in down a chimney for injection moulding.
Background technology
Injection mo(u)lding (Injection Molding), the material that melts that refers to be heated is injected die cavity by high pressure, behind cooling curing, obtains the method for formed products.The method is applicable to the batch production of complex-shaped parts, is one of important processing method.Injection molding process is broadly divided into following 6 stages " matched moulds-injection-pressurize-cooling-die sinking-goods take out ", and above-mentioned technique is carried out repeatedly, just can continuously produce goods.
Injection moulding machine can be divided into mold closing mechanism and injection device.The mold closing mechanism Main Function is to realize that mould opens and closes and eject goods.Existing three template dies are arranged on glue-feeder on the master mold, thereby exist mother module core to affect the defective of the appearance of product.
The utility model content
The utility model purpose: the purpose of this utility model is for the deficiencies in the prior art, and a kind of three template dies that pour in down a chimney for injection moulding are provided, and gum-injecting port is arranged on the male model side, advances glue and must advance from male die core, has overcome the impact of mother module core on Surface Appearance.
Technical scheme: a kind of three template dies that pour in down a chimney for injection moulding described in the utility model, comprise male model side the second fixed head, stripper plate, male model side the first fixed head, male model, master mold and die holder, described master mold is arranged on the male model, be provided with die holder on the described master mold, described male model downside is disposed with male model side the first fixed head, stripper plate and male model side the second fixed head, described male model side is provided with glue-feeder, and sizing material enters die cavity by the male die core on the male model plate.
Accurately locate for the ease of male model and master mold, described male model and master mold are located by connecting by locating dowel and the locating hole that is arranged on four jiaos.
Further, the mouth end of described glue-feeder is arranged on the place, centre position of male model side the second fixed head.
Further, described male model moves by the actuating unit that is arranged on the injection machine.
The utility model compared with prior art, its beneficial effect is: three template dies that pour in down a chimney for injection moulding described in the utility model are exchanged the position of male model and master mold mutually, sizing material enters die cavity by the glue-feeder that is positioned at the male model side from male die core, has overcome the glue-feeder of sizing material by the master mold side and has entered the defective that die cavity affects Surface Appearance from mother module core.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The below is elaborated to technical solutions of the utility model, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of three template dies that pour in down a chimney for injection moulding, comprise male model side the second fixed head 1, stripper plate 2, male model side the first fixed head 3, male model 4, master mold 5 and die holder 6, described master mold 5 is arranged on the male model 4, and described male model 4 and master mold 5 are located by connecting by locating dowel and the locating hole that is arranged on four jiaos.Be provided with die holder 6 on the described master mold 5, described male model 4 downsides are disposed with male model side the first fixed head 3, stripper plate 2 and male model side the second fixed head 1, described male model 4 sides are provided with glue-feeder, and the mouth end 7 of described glue-feeder is arranged on the place, centre position of male model side the second fixed head 1.Sizing material enters die cavity by the male die core on the male model 4.Described male model 4 moves by the actuating unit that is arranged on the injection machine.
Above-mentioned three template dies are exchanged male model 4 mutually with the position of master mold 5, sizing material enters die cavity by the glue-feeder that is positioned at the male model side from male die core, have overcome the glue-feeder of sizing material by the master mold side and have entered the defective that die cavity affects Surface Appearance from mother module core.
As mentioned above, although the specific preferred embodiment of reference has represented and has explained the utility model that it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
Claims (4)
