Abstract
The utility model discloses a telecommunications box forming die, including movable mould and cover half, form the product die cavity when movable mould and cover half compound die, be provided with ejector pin subassembly and sliding block set spare on the movable mould, sliding block set spare is including the slider of putting the injection molding material head, is provided with the drive slider on the slider to right translation's oblique guide pillar, and the ejector pin subassembly includes the stub bar ejector pin, and slider and the first counterbalance of injection molding material are passed to stub bar ejector pin upper end, are provided with the ejecting core that makes progress in the stub bar ejector pin. The utility model discloses simple structure can solve the injection molding material head and inject the position collision problem that the runner takes place when the die sinking.
Description
Technical field
The utility model relates to injection mold field, especially relates to a kind of telecommunications box mould.
Background technology
A kind of processing method of using when injection mo(u)lding is some complex-shaped parts of batch production. Specifically refer to be heated thawingMaterial inject die cavity, after cooling curing, obtain products formed. Injection mold is a kind of instrument of producing plasthetics;Also be the instrument of giving plasthetics complete structure and accurate dimension. Injection mold is generally by dynamic model and cover half two parts groupBecome, dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine. At noteDynamic model and cover half closed formation running gate system and die cavity while penetrating moulding, when die sinking, dynamic model separates to take out plastics with cover halfProduct.
Although the structure of mould is according to plastics variety and performance, the shape of plastic products and the type of structure and injector etc.Different and ever-changing, but basic structure is consistent, mainly by running gate system, forming part, gas extraction system,Temperature control system and ejection system composition. Wherein running gate system and forming part are and the direct contact portion of plastics, and with plasticsChanging with goods, is the most complicated in mold, changes maximum, requires processing fineness and the highest part of precision; CastSystem refers to the runner section of plastics from nozzle enters die cavity, comprises sprue, cold slug well, runner and cast gate etc.Forming part refers to the various parts that form article shape, comprises dynamic model, cover half and die cavity, core, curved lever and rowGas port etc.
As shown in Figure 1, product must first eject injection molding stub bar 4 from the demoulding in this telecommunications box mould, and injection molding stub bar 4Be positioned at injection flow passage 44 under, if in the time of product stripping, directly eject injection molding stub bar 4, injection molding stub bar 4 will certainlyCollide with injection flow passage 44, cause the destruction of mould structure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of telecommunications box mould, and this mould is by a kind of mechanismCan solve the position collision problem that injection molding stub bar and injection flow passage occur in the time of die sinking.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of telecommunications box mould, comprises movingMould and cover half, form product die cavity when described dynamic model and cover half matched moulds, is provided with push rod component and cunning on described dynamic modelBlock assembly, described slide block assembly comprises the slide block that is placed with injection molding stub bar, is provided with and drives slide block to the right on described slide blockThe Angle Pin of translation, described push rod component comprises stub bar push rod, described stub bar push rod upper end is through slide block and injection molding materialHead offsets, and in described stub bar push rod, is provided with the fuse upwards ejecting;
Described slide block is driven to right translation by Angle Pin, is placed on the injection molding stub bar on slide block, and passes the material of slide blockCrown bar is taken out of by slide block simultaneously, and described injection molding stub bar is finally upwards ejected by the fuse being arranged in stub bar push rod.
Further improve as the utility model, described push rod component also comprises push rod slide, in described push rod slideBe provided with slideway, described stub bar push rod bottom is arranged in slideway and can in slideway, slides.
Further improve as the utility model, on described cover half, be provided with sprue bush.
Further improve as the utility model, between described dynamic model and cover half, setting party is to guide pillar.
Further improve as the utility model, between described dynamic model and cover half, be provided with retaining mechanism.
Compared with prior art, the utility model has the advantage of can smoothly injection molding stub bar be ejected and not with injection flow passageBump against, after utilizing slide block that injection molding stub bar is laterally shifted out, recycling push rod ejects injection molding stub bar, avoid in the time of die sinking,Injection flow passage and injection molding stub bar bump against. Specifically, this mould comprises dynamic model and cover half, simple in structure, is being placed with injection mouldingOn the slide block of stub bar, be provided with the Angle Pin being connected with dynamic model, in the time that dynamic model vertically declines, Angle Pin can drive slide block toRight translation, meanwhile, passes the stub bar push rod of slide block also along with slide block is to right translation, due to injection molding stub bar and stub bar topBar offsets, and when slide block is after right translation one segment distance, utilizes the fuse in stub bar push rod that injection molding stub bar is ejected.
Brief description of the drawings
Fig. 1 is the utility model structure.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples,The utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain thisUtility model, and be not used in restriction the utility model.
As shown in Figure 1: a kind of telecommunications box mould, comprises dynamic model 1 and cover half 2, when dynamic model 1 and cover half 2 matched mouldsForm product die cavity, be provided with push rod component and slide block 3 assemblies on dynamic model 1, slide block 3 assemblies comprise and are placed with injection molding stub bar4 slide block 3, is provided with on slide block 3 and drives the Angle Pin 5 of slide block 3 to right translation, and push rod component comprises stub bar push rod 6,Stub bar push rod 6 upper ends offset through slide block 3 and injection molding stub bar 4, are provided with the fuse 8 upwards ejecting in stub bar push rod 6;
Slide block 3 is driven to right translation by Angle Pin 5, is placed on the injection molding stub bar 4 on slide block 3, and through slide block 3Stub bar push rod 6 taken out of by slide block 3 simultaneously, injection molding stub bar 4 is finally by being arranged on fuse 8 in stub bar push rod 6 upwardsEject.
Push rod component also comprises push rod slide 7, in push rod slide 7, is provided with slideway, and stub bar push rod 6 bottoms are arranged on cunningIn road and can slide in slideway. On cover half 2, be provided with sprue bush. Between dynamic model 1 and cover half 2, setting party is to guide pillar.Between dynamic model 1 and cover half 2, be provided with retaining mechanism.
