Abstract
The invention provides an injection mold. The injection mold comprises an upper mold and a lower mold, wherein a plurality of mold cores are arranged on the upper mold and include a pushing mold core and a slanted block mold core; the pushing mold core is pushed by a pushing block via a spring part; the slanted block mold core is pushed by a push rod. The injection mold has the beneficial effects that the pushing mold core and the slanted block mold core are arranged and are pushed by utilizing the spring part and the push rod; the slanted block mold core is pushed by utilizing the push rod, so that the slanted block mold core not only has the functions of the mold core but also plays a role in pushing finished plastic parts; the injection mold has a simple structure, saves the production cost and can conduce to reducing the mold making and production difficulty.
Description
Technical field
The present invention 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 usually can need to offer a some holes in some are little and particularly as the shape of some complexity involved in the present invention, 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.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of injection mold being provided with two cores.
For realizing above object, technical scheme of the present invention 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.
Apparatus of the present invention promote 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 structure of the present invention is simple, save production cost, Mold Making production difficulty can be reduced.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, 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 invention.
Accompanying drawing explanation
Fig. 1 principle schematic of the present invention
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, for structural representation of the present invention, the present invention includes 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 apparatus of the present invention work, 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 the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
