Abstract
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, 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.The utility model 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.
Description
Technical field
The utility model 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 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 injection mold, solve the problem, and makes it more have value in industry.
Utility model content
For solving the problems of the technologies described above, problem to be solved in the utility model is to provide a kind of injection mold.
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 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, described upper core 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 beneficial effects of the utility model are, the utility model 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 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 the utility model principle schematic
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 the structural representation of a kind of injection mold of the utility model, the utility model comprises mold and bed die, and 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 the injection moulding of the utility model plastics; 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 utility model with lower core 3.
During the work of the utility model device, cylinder 11 promotes mold and compresses bed die, upper core 5 enters lower core 3, upper core 5 struts by push rod 8, injection molding channel 7 is by plastic injection influent stream road 2, and push rod 8 moves downward and strutted by upper core 5, forms moulding, after waiting for moulding cooling, mold promotes to leave bed die by guide pillar 9.
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.
