Description
Technical field
The present invention relates to the injection mold field of tableware processing, particularly relate to a kind of chopsticks injection with location and determine
Model core.
Background technology
Throwaway chopsticks obtain typically by the mode of moulding by casting, in prior art, in order to improve the manufacture of chopsticks
Efficiency, many of usual one-time cast-forming, and during many chopsticks of molding, also exist that molding effect is bad, injection agent
Can not be evenly distributed to the situation of every chopsticks, therefore, the quality of the chopsticks that molding obtains is uneven, and percent defective is many, produces
Cost improves, and chopsticks outward appearance concordance is poor, and to carrying out follow-up processing after molding, packing and all make troubles.Due to injection
Mould is under pressure and the impact of temperature in injection molding process, and easily produce on location between its template and core is inclined
Difference, makes the position of mold parting surface that deviation to occur, causes and produce the defects such as burr on plastic product, need to set up edging work separately
Sequence, adds preparation cost prepared by plastics, there is also the situation that plastic damages, improve percent defective, make time serious
Become the waste of the resources of production.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of chopsticks injection fixed mold with location, and it designs conjunction
Reason, simple in construction, the quality for throwaway chopsticks molding that positions solved in the structure of fixed mold affects problem.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is to provide a kind of chopsticks note with location
Mould fixed mold, including forming part and installation portion；The front end surface of described forming part is provided with anterior location；Described anterior location
It is located at turn around on axle center；The radius of gyration of described installation portion is more than the radius of gyration of described forming part；The front end of described forming part
Rotary surface is provided with reinforcement district.
Preferably, described installation portion is stair-stepping revolving body；On the surface, junction of described installation portion and forming part
It is provided with the turning slot of radially indent, and the cross section of this turning slot is circular arc.
The invention has the beneficial effects as follows: providing a kind of chopsticks injection fixed mold with location, it is reasonable in design, processing
Accurately, can be efficient, high-quality produce throwaway chopsticks.And, the throwaway chopsticks prepared by this mold cores, knot
Structure is reasonable, and quality is tight, and intensity is high, good toughness.

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 chopsticks injection fixed mold with location, this cover half has corresponding die assembly and coordinates, becomes a whole set of one
Secondary property chopsticks injection molding mould.Such as shown in Fig. 7, a whole set of processing mold includes upper cover plate 11, pressing plate under upper successively
12, fixed plate 13, template and lower cover 18.And template is four pieces of independent master molds combines, they are respectively the first master mold
14, the second master mold the 15, the 3rd master mold 16 and the 4th master mold 17, four pieces of master molds offers corresponding inner chamber respectively, these inner chambers
Inwall on 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, is then used in the die cavity of dynamic mould core
Coordinating fixed mold, fixed mold i.e. processes the throwaway chopsticks of hollow, and fixed mold has possessed on molding throwaway chopsticks
The ability of hollow area inner structure.
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 shown in Figure 4, the design in water route 8 is to aid in once
The molding of property chopsticks, makes throwaway chopsticks outwards add quickly cooling from inner chamber by the water route offered in the axial direction of fixed mold
But molding, the water route cooling in template in auxiliary whole set of die simultaneously so that the better ideal of chopsticks molding, the most also
Improve 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 disposable chopsticks
Reinforcement muscles and bones one-shot forming on sub-inner chamber, improves intensity and the toughness of throwaway chopsticks.Due to the structural limitation of chopsticks, with
And in order to strengthen the injection effect of throwaway chopsticks front end, the development length in water route 8 is whole relative to forming part less than strengthening district
The proportional positions of body length.As shown in Figure 6, the die cavity inwall of dynamic mould core is provided with the anti-skidding lines 9 of straight shape of stripes, and this is prevented
Sliding 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.
