Abstract
The utility model discloses a trimming knife for an injection molding piece. The trimming knife comprises a knife body, wherein a sharp corner cutting edge is arranged at one end of the knife body; and a cambered cutting edge connected with the root of the sharp corner cutting edge is arranged beside the sharp corner cutting edge and is arranged on the knife body. By the structure, the trimming knife has the following advantages that 1, phenomena of edge failure, joint traces, trimming gaps and the like which are caused during trimming are avoided, the appearance of a product is not influenced, the structure is simple, and the trimming knife is easy to process; 2, a special purchase tool is not needed, and the trimming knife can be ground by a small-size hacksaw blade through a grinding machine; and 3, narrow edges and turnup edges of small holes can be trimmed at the same time.
Description
Technical field
The utility model relates to plastic product post processing overlap dressing technique, particularly a kind of moulding edge iron.
Background technology
Working of plastics occurs overlap in injection moulding production by the parting line place that is everlasting, for guaranteeing product surface quality and appearance and modeling, pair postprocessing working procedures that the product overlap carries out deburring generally after finishing, all can be arranged in injection moulding production, repair the structure chart that overlap is handled as Fig. 3 for product, common cutter is pruned by blade and is protruded the overlap of product surface.But blade and product contact area are very little during the deburring of spraying cutter, firmly uneven during deburring, often cause deburring once to finish, stay the linking trace that repeatedly deburring causes easily, product surface quality is impacted, and because firmly inequality causes working of plastics circular arc limit easily and gnaws the limit and repair scarce phenomenon, cause damage for the outward appearance of product.The point of a knife part acutance of common cutter is bigger, is difficult for putting into carrying out deburring in narrow limit and the aperture.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of and guarantees when deburring, can not damage the moulding edge iron of product appearance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of moulding edge iron, comprise cutter hub, and an end of described cutter hub is provided with the wedge angle blade, described wedge angle blade side is provided with the curved blade that is connected with wedge angle blade root, and described curved blade is arranged on the cutter hub.
Described cutter hub is provided with the hypotenuse blade, and described curved blade is connected with the hypotenuse blade.
The utility model adopts said structure, has the following advantages: cause when 1, avoiding deburring and gnaw the limit, be connected trace, repair phenomenons such as scarce, do not damage product appearance, and simple in structure, processing easily; 2, do not need to purchase special-purpose stage property specially, can use small-sized hacksaw blade to grind by abrasive machine: 3, can be used for the overlap finishing of narrow limit and aperture simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure chart of the utility model deburring on moulding;
Fig. 3 is the structure chart of edge iron deburring on moulding in the background technology of the present utility model;
In Fig. 1 ~ Fig. 2,1, cutter hub; 2, wedge angle blade; 3, curved blade; 4, hypotenuse blade; 5, moulding.
The specific embodiment
As Fig. 1 ~ a kind of moulding edge iron shown in Figure 2, comprise cutter hub 1, an end of cutter hub 1 is provided with wedge angle blade 2, and wedge angle blade 2 sides are provided with the curved blade 3 that is connected with wedge angle blade 2 roots, and curved blade 3 is arranged on the cutter hub 1.Cutter hub 1 is provided with hypotenuse blade 4, and curved blade 3 is connected with hypotenuse blade 4.
Change the edge structure of edge iron, by changing the edge structure of edge iron, contact area becomes big when making blade and the deburring of moulding product, guarantees firmly evenly.In order to make blade and moulding 5 contacts area that need deburring become big, change the structure of edge iron blade into wedge angle blade 2, semicircle shape curved blade 3 and hypotenuse blade 4 by straight sword and form.Such structure makes edge iron when deburring and moulding 5 contacts area become big, firmly evenly, can once finish the overlap finishing.This hook-shaped edge iron and moulding 5 shapes are comparatively fitted, and can not cause damage to the profile of product when deburring, are conducive to improve the presentation quality of product.
Because hook-shaped edge iron and product contact area are big, firmly evenly, can once just finish the finishing of overlap during deburring, trace problem can not appear being connected, and when using stressed evenly, gnaw the limit, repair problem such as scarce, scuffing and also can avoid.The wedge angle blade 2 of hook-shaped edge iron can be used for the deburring of narrow limit and aperture, reduces the operation inconvenience and the fund waste that cause because of the replacing instrument.Hook-shaped edge iron is simple in structure, does not need to buy separately special-purpose stage property manufacturing, only need just can grind on abrasive machine with small-sized hacksaw blade and finish.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
