Preferably, injection flow passage comprises sprue and multiple with die cavity runner one to one, and one end of runner is communicated with the end of sprue, the other end of runner and the die cavity conducting corresponding with it.
Preferably, number of cavity is four.
The beneficial effects of the utility model are:
Compared to prior art, voluminous injection mold of the present utility model, multiple die cavities that can be formed when matched moulds by upper die and lower die, thus can be reached the bend pipe once producing multiple different size, improve production efficiency, save production cost; And this mould adopts and is designed with the side core-pulling of a guiding mechanism driven mold, its simple and stable structure and convenient processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Accompanying drawing illustrates: 10, patrix; 11, injection flow passage; 12, mould bases; 13, internal mold; 14, the first core; 20, counterdie; 21, slide block; 22, the second core; 30, Angle Pin.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
One fecund injection mould as shown in Figure 1, comprises patrix 10, counterdie 20 and for driving the driver part of this mould die sinking/matched moulds.This patrix 10 is provided with multiple first groove, the first core 14, and this first groove is vertically arranged, concrete, and the first core 14 to be arranged in the first groove and along the depth direction of the first groove to downward-extension; Accordingly, counterdie 20 is provided with multiple second groove and multiple second core 22, this concrete second groove and above-mentioned first groove one_to_one corresponding; When matched moulds, fit in medial surface and first core 14 lower surface of this second core 22, the die cavity that the outer surface of the first corresponding when matched moulds like this core 14, the outer surface of the second core 22, the first groove inner wall and the second groove inner wall can coordinate formation consistent with bend pipe structure.Meanwhile, above-mentioned patrix 10 offers injection flow passage 11, and one end of this injection flow passage 11 is communicated with injection machine, the other end and die cavity conducting, and such injection moulding melt enters in die cavity via injection molding channel, facilitates product shaping in die cavity.Concrete, the finished product produced in this voluminous injection mold can be different size, also can be same size, and convenient production, enhances productivity.
In addition, this voluminous injection mold also comprises a guiding mechanism, and specifically this guiding mechanism is used for driving the second core 22 to shift out by the second groove in the horizontal direction when die sinking, carries out side core-pulling.In the present embodiment, this guiding mechanism specifically can comprise Angle Pin 30 and slide block 21, and above-mentioned second core 22 is fixed on this slide block 21.This Angle Pin 30 concrete to be arranged on patrix 10 and to be outward-dipping gradually from top to bottom, this Angle Pin 30 is slidably connected with above-mentioned slide block 21, under the effect of above-mentioned driver part, Angle Pin 30 is up and down, can moving in the horizontal direction with movable slider 21, thus play the effect of side core-pulling, be convenient to the shaping of product.Further, can offer the through hole passed for Angle Pin 30 on this slide block 21, Angle Pin 30 is slidably connected through through hole and slide block 21, can simplify the structure of whole mould like this.Certainly, can arrange other structures on slide block 21 makes Angle Pin 30 be slidably connected with it.Except above-mentioned employing Angle Pin and slide block coordinate with except the guiding mechanism driving the second core 22 to move horizontally, the utility model can also adopt other guiding mechanism, in order to when patrix 10 moves relative to counterdie 20, patrix 10 and moving up and down of counterdie 20 are converted to the horizontal movement of the second core 22.
In the present embodiment, above-mentioned driving mechanism is hydraulic cylinder, can be specifically utilize oil cylinder to drive, and mould structure generally can be made to become comparatively simple, other drive units in addition also can be adopted to drive.
Preferably, counterdie 20 upper surface is provided with sliding tray, slide block 21 activity be arranged in sliding tray, can the scope of activities of slide block 21 be limited in sliding tray like this, also define the scope of activities of above-mentioned Angle Pin 30 simultaneously, improve the production precision of whole mould.
Preferably, above-mentioned patrix 10 can comprise mould bases 12 and internal mold 13, and this internal mold 13 is bolted on mould bases 12.Owing to mostly adopting precious metal to make mould bases 12 during production mould, and internal mold 13 can exchange, and in this mould, adopts this bolt fastening structure, can directly replace internal mold 13 and without the need to changing mould bases 12 when internal mold 13 damages, cost-saving like this.
Preferably, above-mentioned injection flow passage 11 mainly comprises sprue and multiple with die cavity runner one to one, and one end of runner is communicated with the end of sprue, the other end of runner and the die cavity conducting corresponding with it.Raw material is imported in different die cavities by different runners by injection moulding melt in sprue respectively, facilitates formed product like this.In addition, runner can be arranged between two between die cavity, facilitates the abundant flowing of raw material like this, makes full use of raw material.
Preferably, the number of die cavity can be specifically four, and the structure of mould can be made so more to rationalize.Certainly, when producing, can only use one of them or two die cavities to produce, specifically depending on output.
Specifically when this mold work, upper and lower mould 20 is in the state of matched moulds, injection moulding melt is injected in die cavity by injection flow passage 11, after treating formed product, die sinking is carried out under the effect of driver part, during die sinking, first core 14 upwards can be extracted out along with the motion of patrix 10, and in patrix 10 moves the process that moves upward, Angle Pin 30 can be with movable slider 21 along moving in the horizontal direction, and the second core 22 be now fixed on slide block 21 moves thereupon, reach the effect of side core-pulling, so, whole bend pipe is processed good, is taken out by finished product.Certainly, when not needing to produce a lot of finished product, unwanted die cavity can be blocked, preventing raw material from entering, can economize in raw materials, carrying out reasonable production.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
