Its reasonable in design of this fixed mold, the location is accurate, can be high -efficient, high -quality produce disposable chopstick. And rational in infrastructure through the disposable chopstick that this mold core prepared out, the texture is inseparable, and intensity is high, and toughness is good.
Description
Technical field
This utility model is related to the injection mold field of tableware processing, more particularly to a kind of chopsticks note with positioning
Mould fixed mold.
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, exist that molding effect is bad, injection agent
The situation of every chopsticks can not be evenly distributed to, therefore, the quality of the chopsticks that molding obtains is uneven, and percent defective is many, produce
Cost improves, and chopsticks outward appearance concordance is poor, and to carrying out follow-up processing after molding, pack and all make troubles.Due to injection
The impact that mould is under pressure with temperature in injection molding process, easily produces inclined in positioning between its template and core
Difference, makes the position of mold parting surface that deviation to occur, causes and produce the defects such as burr on plastic product, need separately to set up edging work
Sequence, increased the preparation cost of plastics preparation, there is also the situation of plastic damage, improve percent defective, make when serious
Become the waste of the resources of production.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of chopsticks injection fixed mold with positioning, it sets
Rationally, structure is simple for meter, and the positioning solving in the structure of fixed mold affects problem for the quality of throwaway chopsticks molding.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is to provide a kind of chopsticks with positioning
Son injection fixed mold, including forming part and installation portion；The front end surface of described forming part is provided with anterior positioning；Described front portion
Positioning is located in revolution axle center；The radius of gyration of described installation portion is more than the radius of gyration of described forming part；Described forming part
Front end rotary surface is provided with reinforcement area.
Preferably, described installation portion is stair-stepping revolving body；On the junction surface 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 in circular arc.
The beneficial effects of the utility model are：There is provided a kind of chopsticks injection fixed mold with positioning, it is reasonable in design,
Precision machining, can be efficient, high-quality produce throwaway chopsticks.And, the disposable chopsticks prepared by this mold cores
Son, rational in infrastructure, closely, intensity is high, good toughness for quality.

Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
Refer to accompanying drawing 1 to 7, this utility model embodiment includes：
A kind of chopsticks injection fixed mold with positioning, this cover half has corresponding die assembly cooperation, becomes a whole set of
Throwaway chopsticks injection molding mould.For example shown in Fig. 7, a whole set of processing mold include successively under upper upper cover plate 11,
Pressing plate 12, fixed plate 13, template and lower cover 18.And template is four pieces of independent master molds combines, they are respectively first
Master mold 14, the second master mold 15, the 3rd master mold 16 and the 4th master mold 17, four pieces of master molds offer corresponding inner chamber respectively, these
On the inwall of inner chamber or be provided with water route mouth；Coordinate corresponding mold cores in the inner chamber of master mold, mold cores then comprise dynamic model
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 is then
It is used for coordinating fixed mold, fixed mold processes the throwaway chopsticks of hollow, and fixed mold possesses the disposable chopsticks of molding
The ability of hollow area inner structure on son.
Fixed mold is in 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 junction surface of forming part are provided with the turning slot 10 of radially indent, and the cross section of this turning slot 10 is in circular arc
Shape, this turning slot 10 is used for the rear end face edge formation of throwaway chopsticks.Anterior positioning 3 is provided with the front end face of forming part 1,
Anterior positioning 3 is located at turn around on axle center, and this front portion positioning 3 can play the molding effect of workpiece, and can make
Obtaining fixed mold guarantees accurate positioning in the structure.Anterior positioning 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 opens up from the rear end face of fixed mold, water route 8
Axial direction along fixed mold the extension of the front end to fixed mold.As shown in figure 4, the design in water route 8 is to aid in once
Property chopsticks molding, by the water route opening up in the axial direction of fixed mold, throwaway chopsticks are outwards accelerated from inner chamber cold
But molding, simultaneously in auxiliary whole set of die the water route cooling in template so that the better ideal of chopsticks molding, simultaneously
Improve working (machining) efficiency.Reinforcement area 4 is provided with the front end rotary surface of forming part, this reinforcement area 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 with respect to forming part less than strengthening area
The proportional positions of body length.As shown in fig. 6, the die cavity inwall of dynamic mould core is provided with the anti-skidding lines 9 of straight shape of stripes, this is prevented
Sliding lines 9 can process skid resistance strip in the holding zone on throwaway chopsticks, improves the using effect of chopsticks.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using this utility model description or equivalent flow conversion, or directly or indirectly it is used in other phases
The technical field closed, is all included in the same manner in scope of patent protection of the present utility model.
