Abstract
The invention discloses an ox horn shaped plastic feeding structure which comprises an ox horn shaped runner. A first opening and a second opening are respectively arranged at two ends of the rubber, and the section of the runner is in the shape of a rectangle with four arced corners. By designing the section of the runner into the shape of the rectangle, area of the runner can be enlarged, and accordingly quantity of fed plastic is increased. Meanwhile, by designing the four corners of the rectangle into arc shapes, generation of 'dead angle' of the runner is avoided, and working efficiency is improved.
Description
Technical field
The present invention relates to a kind of ox horn and advance plastic structure, belong to plastic mould and make the field.
Background technology
Injection molding technology is one of industrial production technology of present extensive use, almost is applicable to all thermoplastics, also is applicable to some thermosets.The molding cycle of injection mo(u)lding is short, and Forming Quality is high, can the one-shot forming complex contour, size accurately, have the moulded work of metal or non-metallic insert, ox horn advances plastic structure and is widely used in the plastic mould.But the cross section of ox horn type runner is circular mostly in the prior art, because the runner openings at two ends differs in size, the flowing velocity of plastic cement in runner is slower, and it is less to advance the glue amount, and operating efficiency is lower.
Summary of the invention
Deficiency to prior art the objective of the invention is to, and provides a kind of ox horn to advance plastic structure, increases work efficiency through the cross sectional shape that changes runner.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of ox horn advances plastic structure, comprises the runner of an ox horn type, and the two ends of said runner are respectively first opening and second opening; It is characterized in that: the cross section of said runner is a rectangle, and four angles of said rectangle are circular-arc.
Aforesaid a kind of ox horn advances plastic structure, it is characterized in that: the sectional dimension of said first opening is greater than the sectional dimension of said second opening.
Aforesaid a kind of ox horn advances plastic structure, it is characterized in that: the die cavity cross section of the cross section of said second opening and injecting products has angle.
Aforesaid a kind of ox horn advances plastic structure, it is characterized in that: described angle is less than 90 °.
The invention has the beneficial effects as follows: the cross section of runner is made as rectangle, can increases the area of runner, thereby increase the glue amount, simultaneously four angles of rectangle are made as circular-arcly, can prevent the generation at runner " dead angle ", improved the efficient of work.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
For further disclosing technical scheme of the present invention; Specify embodiment of the present invention below in conjunction with accompanying drawing: as shown in Figure 1; A kind of ox horn advances plastic structure; The runner 1 that comprises an ox horn type, the two ends of runner 1 are respectively the sectional dimension of the sectional dimension of first opening 2 and second opening, 3, the first openings 2 greater than second opening 3.The cross section of runner 1 is a rectangle 4, can increase the area of runner, advances the glue amount thereby increase, and increases work efficiency.Four angles of rectangle 4 are circular-arc, can prevent the generation at runner " dead angle ".The cross section of second opening 3 and the die cavity of injecting products 6 cross sections have angle 5, and this angle 5 is convenient to plastic cement and is got into die cavity 6 less than 90 °.
More than, basic design of the present invention and basic principle have been set forth through introduction to listed embodiment.But the present invention never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technical scheme of the present invention of change all should belong to protection scope of the present invention.
Claims (4)
1. an ox horn advances plastic structure, comprises the runner of an ox horn type, and the two ends of said runner are respectively first opening and second opening, it is characterized in that: the cross section of said runner is a rectangle, and four angles of said rectangle are circular-arc.
2. a kind of ox horn according to claim 1 advances plastic structure, it is characterized in that: the sectional dimension of said first opening is greater than the sectional dimension of said second opening.
