Abstract
The invention discloses a kind of injection molds, including casting system, it include an injection molding sprue and injection molding runner in running gate system, it is molded runner communicate-type chamber, its structural feature is: the injection molding sprue is screw type runner, the port for being molded sprue is back taper, and injection molding runner is equipped with screw valve.The beneficial effects of the present invention are: structure is simple, design is reasonable.Injection molding sprue is designed as spiral shape, injection molding sprue and the junction for being molded runner are set as arc, impact of the material of high pressure injection to injection molding runner can effectively be slowed down, the equally distributed protrusion of injection molding sprue inner wall also has certain unhurried current effect；The port for being molded sprue uses back taper, can play the role of pressurization, keeps material flow rates stronger more stable；Each injection molding runner is equipped with screw valve, and for controlling the stream creeping amount of injection molding runner, the material for keeping type intracavitary is reasonably distributed, Improving The Quality of Products.
Description
Technical field
The present invention relates to mould applications, and in particular to be a kind of injection mold.
Background technique
A kind of mold that injection mold uses when being using injection molding forming method.Injection molding refers to the material of heated thawing
Die cavity is injected by high pressure, after cooling and solidifying, the method that obtains formed products.Injection mold refers to that resin material injects metal pattern
The device for having effigurate product is obtained afterwards.
In the prior art, when material injects injection molding sprue by high pressure, material flow rates are uneven, can produce to injection molding runner
Raw certain impact, causes plastic finished product edge formation effect poor.
Summary of the invention
In order to solve the above technical problems, the material pair of high pressure injection can be slowed down the present invention provides a kind of injection mold
The impact of type chamber.
It include that an injection molding is led in running gate system the technical solution of the present invention is as follows: a kind of injection mold, including casting system
Runner and injection molding runner are molded runner communicate-type chamber, and the injection molding sprue is screw type runner, are molded sprue
Port be back taper, injection molding runner be equipped with screw valve.
As the further improvement of invention, the axial direction of the injection molding sprue and the axial direction of injection molding runner are perpendicular,
Injection molding sprue is that arc is connect with the junction for being molded runner.
As the further improvement of invention, the injection molding sprue inner wall is uniformly distributed protrusion.
As the further improvement of invention, the injection molding runner quantity is more than or equal to two.
As the further improvement of invention, the screw valve and injection molding runner are connected through a screw thread.
The beneficial effects of the present invention are: structure is simple, design is reasonable.Injection molding sprue is designed as spiral shape, injection molding master
The junction of runner and injection molding runner is set as arc, can effectively slow down the material of high pressure injection to injection molding runner
Impact, the equally distributed protrusion of injection molding sprue inner wall also have certain unhurried current effect；The port for being molded sprue uses
Taper can play the role of pressurization, keep material flow rates stronger more stable；Each injection molding runner is equipped with screw valve,
For controlling the stream creeping amount of injection molding runner, the material for keeping type intracavitary is reasonably distributed, Improving The Quality of Products.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the enlarged diagram of part A of the present invention；
Wherein, 1- feed inlet, 2- are molded sprue, and 3- is molded runner, 4- screw valve, and 5- is molded sprue port.
Specific embodiment
Invention is described further with reference to the accompanying drawings and examples:
As depicted in figs. 1 and 2, a kind of injection mold, including casting system, include in running gate system an injection molding sprue and
It is molded runner, is molded runner communicate-type chamber, the injection molding sprue is screw type runner, and the port for being molded sprue is
Back taper, injection molding runner are equipped with screw valve.
In the present embodiment, the axial direction of the injection molding sprue and the axial direction of injection molding runner are perpendicular, are molded mainstream
Road is that arc is connect with the junction of injection molding runner.
In the present embodiment, the injection molding sprue inner wall is uniformly distributed protrusion, the screw valve and injection molding point
Runner is threadably secured.Screw valve is used to control the stream creeping amount of runner, and the material for keeping type intracavitary is reasonably distributed, can
Promote the quality of production of product.
In the present embodiment, injection molding sprue is designed as spiral shape, the junction of sprue and runner is set as arc
Shape can effectively slow down impact of the material of high pressure injection to unhurried current road and type chamber, the equally distributed protrusion of sprue inner wall
Also there is certain unhurried current effect；The port for being molded sprue uses back taper, can play the role of pressurization, make material flow rates
It is stronger more stable.
In addition, the injection molding sprue inner wall can also be used other sections and generate slow speed effect, such as sawtooth pattern, streamline
Type etc..
In addition, the injection molding runner is not limited to quantity, is molded between sprue and injection molding runner except use
Arc connection is outer, and area of section also can be used and be replaced greater than injection molding sprue with the geometric figure for being molded runner, meet
The primitive rule of connection.
In addition to the implementation, all technical solutions formed using equivalent substitution or equivalent transformation, are all fallen within the present invention and wanted
The protection scope asked.
