Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to accompanying drawing 1 to 7, the embodiment of the present invention includes:
A kind of mold cores for throwaway chopsticks injection molding, this mold cores has corresponding die assembly and coordinates, becomes
For a whole set of throwaway chopsticks injection molding mould.Such as shown in Fig. 2, a whole set of processing mold includes upper cover under upper successively
Plate 11, pressing plate 12, fixed plate 13, template and lower cover 18.And template to be four pieces of independent master molds combine, they are respectively
First master mold the 14, second master mold the 15, the 3rd master mold 16 and the 4th master mold 17, four pieces of master molds offer corresponding inner chamber respectively,
On the inwall of these inner chambers or be provided with water route mouth；Coordinating corresponding mold cores in the inner chamber of master mold, mold cores then comprises
Dynamic mould core and fixed mold.The cavity design of dynamic mould core is the external shape of throwaway chopsticks, in the die cavity of dynamic mould core
Then being used to coordinate fixed mold, fixed mold i.e. processes the throwaway chopsticks of hollow, and fixed mold has possessed molding once
The ability of hollow area inner structure on property chopsticks.
Fixed mold is the cavity shape of throwaway chopsticks, and dynamic mould core is set on fixed mold.Fixed mold includes
Forming part 1 and installation portion 2, the radius of gyration of installation portion 2 is more than the radius of gyration of forming part 1.Installation portion 2 is stair-stepping revolution
Body, installation portion 2 includes spacing section 5, cooperation section 6 and the linkage section 7 that radial dimension successively decreases successively, and spacing section 5 is used for coordinating master mold
Upper corresponding installing hole, the end of linkage section 7 is connected with forming part, and the end of linkage section 7 is the pyramidal structure of multiaspect.Connect
Section and the surface, junction of forming part are provided with the turning slot 10 of radially indent, and the cross section of this turning slot 10 is circular arc
Shape, this turning slot 10 is for the rear end face edge formation of throwaway chopsticks.The front end face of forming part 1 is provided with anterior location 3,
Anterior location 3 is located at turn around on axle center, and the molding effect of workpiece can be played in location, this front portion 3, and can make
Obtain fixed mold and guarantee accurate positioning in the structure.Anterior location 3, in the forming process of workpiece, can form throwaway chopsticks
Small sircle hole on front end face.The shaft core of fixed mold is provided with water route 8, and water route 8 is offered from the rear end face of fixed mold, water route 8
Axially and extending to the front end of fixed mold along fixed mold.As it can be seen, the design in water route 8 is to aid in disposably
The molding of chopsticks, makes throwaway chopsticks outwards accelerate cooling from inner chamber by the water route offered in the axial direction of fixed mold
Molding, the water route cooling in template in auxiliary whole set of die simultaneously so that the better ideal of chopsticks molding, also carry simultaneously
High working (machining) efficiency.Being provided with reinforcement district 4 on the front end rotary surface of forming part, this reinforcement district 4 is so that throwaway chopsticks
Reinforcement muscles and bones one-shot forming on inner chamber, improves intensity and the toughness of throwaway chopsticks.Due to the structural limitation of chopsticks, and
In order to strengthen the injection effect of throwaway chopsticks front end, the development length in water route 8 is overall relative to forming part less than strengthening district
The proportional positions of length.As it can be seen, the die cavity inwall of dynamic mould core is provided with the anti-skidding lines 9 of straight shape of stripes, this is anti-skidding
Lines 9 can process anti-skidding striped in the holding zone on throwaway chopsticks, improves the using effect of chopsticks.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks
Territory, is the most in like manner included in the scope of patent protection of the present invention.
