Abstract
The utility model discloses a sub-channel remodeling structure of a plastic mould. The sub-channel remodeling structure of the plastic mould comprises a main flow channel (50) and a sub-channel (60), wherein an arc-shaped sub-channel (20) is arranged at the position between the sub-channel (60) on the side edge of a product and a feed port (80) of a product mould cavity (10); and a cold material well (70) is arranged at the connection position of the arc-shaped sub-channel (20) and the sub-channel (60). The arc-shaped sub-channel can change the flowing direction of a glue inlet fusant, thereby overcoming the defects that the glue inlet fusant is directly directly injected into the product mould cavity through the feed port so as to cause that flow marks exist on the made-up product in the product mould cavity finally, and the like; and the effects such as light transmission, light guide quality of the made-up product in the product mould cavity are improved.
Description
Technical field
The utility model relates to a kind of plastic mould, especially relates to the plastic mould runner modified structure of a kind of use and perspex goods.
Background technology
Transparent plasthetics is often as appearance part or light guide member.As make the surface exposure that appearance part then shows as these manufactured goods, and naked eyes can direct viewing, is equivalent to glass on the function, and requirement is that extraordinary light transmission is arranged, and sees through it and can see the thing of back; And when being used for making light guide, then usually use with other component combination, in the function that is used in combination middle realization leaded light, when light source during by it, realize the function of light conduction.Find out from above 2, no matter above-mentioned which kind of use, all the moulding of manufactured goods had very high requirement, require the defectives such as bubble, current mark can not occur in the manufactured goods, if because exist the defectives such as bubble and current mark can have a strong impact on the performances such as its printing opacity, leaded light.
The utility model content
The utility model the defectives such as bubble, current mark occur easily for the plastic mould that solves existing perspex goods in the manufactured goods of injection mo(u)lding, thereby causes reducing the present situation such as its printing opacity, leaded light performance and a kind of plastic mould runner modified structure that can avoid to a greater extent occurring occurring easily in the manufactured goods defectives such as bubble, current mark of providing.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that adopts to be: a kind of plastic mould runner modified structure, comprise sprue and runner, it is characterized in that: enter at the runner of goods side that the position is provided with the arc runner between the charging aperture of goods die cavity.The arc runner can make and change the flow direction that advances the glue melt, prevent from directly injecting by charging aperture causing the product of finally in the goods die cavity, making the defectives such as current mark to occur in the goods die cavity thereby reach, reach and improve product printing opacity, the light conductivity quality texts of making in the goods die cavity.
As preferably, the junction of described arc runner and runner is provided with slag well.Slag well can prevent better that cold burden from partly entering in the goods die cavity, avoids causing each several part inhomogeneous cooling phenomenon in the goods die cavity, thereby reaches the quicker as much as possible whole goods die cavity that is full of, and to prevent from avoiding the appearance of bubble, improves the quality of making product.
As preferably, described arc runner is the U-shaped shape runner with semi arch.Reach and better make the effect that changes the flow direction that advances the glue melt.
As preferably, described goods die cavity is provided with the exhaust translot in the side away from the arc runner.Improve the smooth gas discharge of mould, improve the total quality of making product thereby reach.
The beneficial effects of the utility model are: the arc runner can make and change the flow direction that advances the glue melt, prevent from directly injecting by charging aperture causing the product of finally in the goods die cavity, making the defectives such as current mark to occur in the goods die cavity thereby reach, reach and improve product printing opacity, the light conductivity quality texts of making in the goods die cavity.
And can prevent better that cold burden from partly entering in the goods die cavity, improve the smooth gas discharge of mould, avoid causing each several part inhomogeneous cooling phenomenon in the goods die cavity, thereby reach the quicker as much as possible whole goods die cavity that is full of, to prevent from avoiding the appearance of bubble, improve the quality of making product.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the preferred embodiment of the utility model plastic mould runner modified structure.
Fig. 2 is the side-looking structural representation of the utility model plastic mould runner modified structure.
The specific embodiment
Among Fig. 1, the embodiment shown in Figure 2, a kind of plastic mould runner modified structure, comprise sprue 50 and runner 60, enter at the runner 60 of goods side that the position is connected with arc runner 20 between the charging aperture 80 of goods die cavity 10, preferably adopt arc runner 20 for two ends all with the U-shaped shape runner of semi arch.Arc runner 20 1 ends are connected with runner 60, and the other end is connected with the charging aperture 80 of goods die cavity 10, effectively change the flow direction that advances the glue melt.Arc runner 20 is provided with slag well 70 with the junction of runner 60, the front end cold burden is stayed in slag well 70, thereby prevent that cold burden from partly entering in the goods die cavity, effective melt is finally entered in the goods die cavity 10, avoid causing each several part inhomogeneous cooling phenomenon in the goods die cavity.Goods die cavity 10 is provided with exhaust translot 30 in the side away from arc runner 20.
During goods, plastics are injection machine liquefies behind high-temperature heating, flow into sprue 50 by sprue bush 40, flow to again runner 60, when arriving arc runner 20, can stay the front end cold burden in slag well 70, melt finally enters in the goods die cavity 10, and the air in the goods die cavity is extruded into exhaust translot 30 places, through the pressurize cooling, obtain the final product of making.
Although this paper has more used the terms such as sprue, runner, goods die cavity, arc runner, charging aperture, exhaust translot; But do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present invention; They are construed to any additional restriction all is contrary with spirit of the present invention.
