Abstract
A kind of injection mold, comprise mold and bed die, described mold is provided with multiple core, described core comprises repulsive-type maglev core and skewback core, and described promotion core is promoted by spring part by pushing block, and described skewback core is promoted by push rod.The utility model device promotes core and skewback core by arranging, spring part and push rod is utilized to promote two cores, utilize push rod to promote skewback core and not only play effect as core also simultaneously as the effect of promotion finished product working of plastics by skewback core, and the utility model structure is simple, save production cost, Mold Making production difficulty can be reduced.
Description
Technical field
The utility model relates to a kind of injection mold.
Background technology
In injection mold now, in die cavity, impression-taking apparatus etc., still there are some shortcomings.At the design aspect of die cavity, although the design of the die cavity that can both compare according to the external form of the mould of required processing, but in some are little, usually can need the shape offering a some holes and some complexity particularly involved by the utility model, then usually can not complete by once-cast in die cavity, and need to be machined by other steps more after shaping, operation very bothers; And at running channel design aspect; due to usual some taked irrational gate design; as caused the inflow velocity of the wax liquid in die cavity slow because flow resistance is large; affect efficiency; in impression-taking apparatus; some traditional moulds can be not easy to the demoulding due to the unreasonable of design usually, lower efficiency.Can find out due to some are unreasonable or be not suitable for process Design of Dies, have impact on the raising of production efficiency to a certain extent, particularly in the large-scale production of industrial development now, this impact is particularly evident, connects the burden that also can consume resource to a certain extent He add enterprise.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of novel injection mold, solve the problem, and makes it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of injection mold being provided with two cores.
For realizing above object, the technical solution of the utility model is as follows:
A kind of injection mold, comprise mold and bed die, described mold is provided with multiple core, it is characterized in that: described core comprises repulsive-type maglev core and skewback core, described promotion core is promoted by spring part by pushing block, and described skewback core is promoted by push rod.
Further, described push rod is arranged in described mold, has certain inclination angle with described patrix.
Further, described skewback core is also provided with holding section, and the effect as core is played in described holding section in injection moulding process, can also play the effect releasing moulding after injection moulding completely.
The utility model device promotes core and skewback core by arranging, spring part and push rod is utilized to promote two cores, utilize push rod to promote skewback core and not only play effect as core also simultaneously as the effect of promotion finished product working of plastics by skewback core, and the utility model structure is simple, save production cost, Mold Making production difficulty can be reduced.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 principle schematic of the present utility model
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, for structural representation of the present utility model, the utility model comprises mold and bed die, wherein mold comprises promotion core 3, spring part 4, pushing block 5, guide pillar 6, guide pin bushing 7, runner 8, push rod 9, skewback core 10, holding section 11, wherein bed die comprises support plate 1, and mold and bed die compress and form die cavity 2.When mold and bed die compress, bed die promotes pushing block 5 and moves upward, and pushing block 5, can holddown spring part 4 casees medial movement with hypotenuse, promote core 3 to the inside mobile and die cavity 2 fits; Guide pillar 6 and guide pin bushing 7 are for mold and bed die to be compressed and separatory; Runner 8 as the stream of plastic of injection moulding through passage; Push rod 9 is arranged in mold, push rod 9 is the angle setting of tilting certain, one end of push rod 9 is connected with skewback core 10, skewback core 10 is provided with holding section 11, wherein the effect as core is played in holding section 11 in injection moulding process, can also play the effect releasing moulding after injection moulding completely.
During the work of the utility model device, mold and bed die compress, and runner 8 flows out injection molding liquid plastics, moulding is formed after entering die cavity 2, after moulding cooling forming, mold is pushed away bed die by guide pillar 7, and shaping moulding is released by skewback core 10 by push rod 9 simultaneously.
The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
