Abstract
The invention provides an injection mold. The injection mold comprises an upper mold and a lower mold, wherein an upper mold core and a push rod are arranged on the upper mold; a lower mold core is arranged on the lower mold; the upper mold core is provided with a deformable part and can enter the lower mold core to form a cavity with the lower mold core. The injection mold has the beneficial effects that through hollow design of the middle part of the upper mold core, the upper mold core is expanded after being extruded and is combined with the lower mold to form the cavity; the injection mold can be used for quickly manufacturing injection-molded parts in specific shapes, has a quite simple structure and is low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of injection mold.
Background technology
In injection mold now, in the die cavity of mould, 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 injection mold, solve the problem, and makes it more have value in industry.
Summary of the invention
For solving the problems of the technologies described above, the problem to be solved in the present invention is to provide a kind of injection mold.
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 core and push rod, described bed die is provided with lower core, it is characterized in that: described upper core is with can the core of deformations, and described mo(u)ld top half can enter into described lower core, forms die cavity with described lower core.
Further, described mo(u)ld top half core inner is hollow, and wherein hollow part narrows via after deformable part.
Further, after narrowing position by deformable part, deformable part is strutted after described push rod enters described hollow part.
Further, described mold is also provided with promotion part, comprises guide pin bushing, guide pillar and cylinder, and described mold compresses and is separated bed die by guide pillar described in described cylinder-pushed.
The invention has the beneficial effects as follows, the present invention by the hollow design in the middle of upper core, makes core be combined with bed die and form die cavity being extruded rear distraction, can manufacture the moulding of given shape fast, structure quite simply, low cost of manufacture.
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 of the invention schematic diagram
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 the structural representation of a kind of injection mold of the present invention, the present invention includes mold and bed die, wherein bed die is provided with support plate 1, support plate 1 is provided with lower core 3, lower core 3 is provided with for injection molding runner 2, mold is provided with core 5, and upper core 5 is with can deformations 6, upper core 5 inner space is that hollow is arranged, wherein inner space is via starting to narrow after deformations, and upper core 5 is also provided with groove 4, for the mould making given shape is used; Mold is provided with injection molding channel 7, for plastics note of the present invention
Mould; Upper core 5 is also provided with push rod 8, and push rod 8 can advance along the inner space of upper core 5 under external force, and enter into can when deformations 6, push rod 8 can will be able to deformations 6 strut; Mold is also provided with promotion part, comprises guide pillar 9, cylinder 10, guide pin bushing 11, and wherein cylinder 11 promotes guide pillar 9 and is separated with bed die by mold; Upper core 5 also constitutes die cavity of the present invention with lower core 3.
During apparatus of the present invention work, cylinder 11 promotes mold and compresses bed die, upper core 5 enters lower core 3, upper core 5 struts by push rod 8, and injection molding channel 7 is by plastic injection influent stream road 2, and push rod 8 moves downward and strutted by upper core 5, form moulding,, after waiting for moulding cooling, mold promotes to leave bed die by guide pillar 9.
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.
