Description
Technical field
The present invention relates to a kind of injection molding process, particularly a kind of router cover forming method.
Background technology
Shell made from plastic parts is widely used in the fields such as mobile communication, electronics, automobile, biomedical devices.It is existing
Plastic parts mostly be molded by injected plastics material after obtain, material is mainly plastic cement.With the continuous improvement of people's living standards,
Requirement for product casing is also improved constantly, for example, wish that plastic parts shell is thinner, more attractive.Correspondingly, gold is also occurred
Belong to the shell of material as the scheme of phone housing, to improve the metal-like of phone housing.Also directly in plastic parts shell
The plated film of upper spray metal texture, to improve electronic product appearance.At present, product casing design how is further optimized,
Electronic product casing is set to possess the appearance of uniqueness, so that product obtains the preferable market share, it is that people make great efforts improved side
To.
The content of the invention
The present invention solves the technical problem of a kind of router cover forming method is provided, road can be effectively improved
By the injection quality of device shell.
In order to solve the above technical problems, one aspect of the present invention is：A kind of router cover shaping is provided
Method, it includes：
First, injection mold is selected according to product type：Two molds needed for formed product are selected, after two mold matched moulds
It is respectively put into dijection forming machine；
Second, modulation plastic material is required according to finished product：Products material is made according to ratio allotment, and by deployed plastic cement
Raw material is added in the feed bin of dijection forming machine；
3rd, injection is injected for the first time：Start dijection forming machine, dijection forming machine injects plastic material in the first mold,
Simultaneously injection finished product is made in first mold heating pressurization；
4th, period 1 shaping：The automatic injection finished product to being made in the 3rd step of dijection forming machine is molded, dijection shaping
Injection finished product is moved in the second mold by machine；
5th, second of injection injection：Dijection forming machine injects plastic material in the second mold again, the second mold
Simultaneously dijection finished product is made in heating pressurization；
6th, equipment die sinking：Dijection finished product is ejected.
Preferably, plastic material needs to be allocated according to product in the second step, and the injection raw material is by gathering
The composite of carbonic ester and glass material composition.
Preferably, the 3rd step is injected in injection moulding process for the first time, and the first mold is warming up to 90 ~ 120 DEG C, pressure
For 10 ~ 15bar, the cycle is 90 ~ 120s.
Preferably, in second of injection injection moulding process of the 5th step, the second mold is warming up to 80 ~ 100 DEG C, pressure
For 15 ~ 20bar, the cycle is 120 ~ 150s.
The beneficial effects of the invention are as follows：A kind of router cover forming method is provided, passes through dijection forming method so that adopt
More protruded, so as to make product that there is higher flexibility, can absorbed with the plastic cement quality of the secondary injection molding of product
The strength that outside is come, it is ensured that product function is stable.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
The embodiment of the present invention includes：A kind of router cover forming method, its step includes：
First, injection mold is selected according to product type：Two molds needed for formed product are selected, after two mold matched moulds
It is respectively put into dijection forming machine；
Second, modulation plastic material is required according to finished product：Injection raw material is the composite being made up of makrolon and glass material, will
Injection raw material is made according to ratio allotment, and deployed plastic material is added in the feed bin of dijection forming machine；
3rd, injection is injected for the first time：Start dijection forming machine, dijection forming machine injects plastic material in the first mold,
First mold is warming up to 90 ~ 120 DEG C, and pressure adds to 10 ~ 15bar, and the durations of temperature and pressure are in 90 ~ 120s, at this
Under the conditions of injection finished product is made；
4th, period 1 shaping：The automatic injection finished product to being made in the 3rd step of dijection forming machine is molded, dijection shaping
Injection finished product is moved in the second mold by machine；
5th, second of injection injection：Dijection forming machine injects plastic material in the second mold again, the second mold
80 ~ 100 DEG C are warming up to, pressure adds to 15 ~ 20bar, the durations of temperature and pressure are made under this condition in 120 ~ 150s
Dijection finished product；
6th, equipment die sinking：Dijection finished product is ejected.By finished product deburring, storage is checked after quality inspection is qualified.
