Abstract
The utility model relates to a delayed die sinking and glue feeding mechanism of a sliding block for an injection mold. The delayed die sinking and glue feeding mechanism comprises a hot runner filling nozzle, an inclined guide pillar and a sliding block, wherein a glue feeding position of the injection mold is arranged on the sliding block, the hot runner filling nozzle is arranged at the position more than 12.73 mm above the glue feeding position, and a fluid runner is formed between the hot runner filling nozzle and the glue feeding position in a female mold core of the mold; a cavity is arranged inside the sliding block, the inclined guide pillar fixed on a female mold of the mold penetrates through the cavity, and an air gap is formed on the side surface close to the outside of the inclined guide pillar and the cavity. The delayed die sinking and glue feeding mechanism adopts the structure, thereby not only avoiding the heating area of the hot runner filling nozzle being too close to the product and influencing the appearance of the product, but also ensuring that the sliding block begins to slide outwards when a cold charge section generated between the hot runner filling nozzle and the glue feeding position is divorced from the female mold core of the mold after glue feeding, so that the problem that the sliding block slides untimely to snap off the cold charge in the female mold core to cause the glue feeding failure of the next mold is avoided.
Description
Technical field
The slide block that the utility model relates to injection mold field, particularly a kind of injection mold is delayed die sinking and is advanced plastic structure.
Background technology
In the forming process of plasthetics, the glue mode of advancing of injection mold has a variety ofly, advances glue as the limit, and point advances glue, the glue of hiding into etc., and these are traditional advances the glue mode and often can see in the process of plastic rubber shaping.And the product of apperance can limits product advance the glue mode, sometimes enter the glue position and need design on slide block, this kind situation is commonly used, and to advance the glue mode be wire dot system, i.e. cast gate can disconnect during die sinking, but the heating region of heat filling mouth is too near from product like this, can influence the outward appearance of product.The existing practice commonly used is that the slide block length of prolongation plastic mould will be advanced the laterally mobile heat that makes of glue point and irritate mouth away from product.If prolong the length of slide block, can strengthen the size of mould, can add the length of progress glue in addition, produce more cold burden and loss injection pressure.
Summary of the invention
The slide block that technical problem to be solved in the utility model provides a kind of injection mold is delayed die sinking and is advanced plastic structure, and this kind structure has well solved cold burden, gas trace, problem such as the pressure loss is big, and pressurize is insufficient.And this kind Stability Analysis of Structures, process easy to assembly.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of slide block of injection mold to delay die sinking and advance plastic structure, comprise hot flow path filling mouth, Angle Pin, slide block, the glue position of advancing of described plastic mould is located on the described slide block, described hot flow path is irritated mouth and is being advanced directly over the glue position greater than the 12.73mm place, in the mother module core of described mould, described hot flow path is irritated mouth and is advanced and forms one section flow channel for liquids between the glue position; There is a cavity described slide block inside, and the described Angle Pin that is fixed on the mould caster passes described cavity, and when slide block during in the extreme higher position, Angle Pin and cavity have the space between outer side.
Described is the tubaeform runner that internal diameter increases gradually advancing to form one section flow channel for liquids between the glue position for irritating mouth to glue-feeder from hot flow path.
The longitudinal section of described slide block internal cavities is a parallelogram, and the inclined plane of cavity is parallel with the axis of Angle Pin.
Beneficial effect
It is many that the present invention has well solved cold burden, gas trace, problem such as the pressure loss is big, and pressurize is insufficient.And Stability Analysis of Structures of the present invention, process easy to assembly.
Description of drawings
The utility model sectional view when Fig. 1 is into glued the bundle.
Fig. 2 is that slide block has just begun the utility model sectional view when mobile.
Fig. 3 is that the dynamic model die sinking finishes back the utility model sectional view.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The present invention includes hot flow path and irritate mouth 2, Angle Pin 4, slide block 5, the glue position of advancing of described plastic mould is located on the described slide block 5, described hot flow path is irritated mouth 2 and is being advanced directly over the glue position greater than the 12.73mm place, in the mother module core 3 of described mould, described hot flow path is irritated mouth 2 and is advanced and forms one section flow channel for liquids between the glue position; There is a cavity described slide block 5 inside, and the described Angle Pin 4 that is fixed on the mould caster 1 passes described cavity, and when slide block during in the extreme higher position, there is the space the outer side of Angle Pin and cavity.
Described is the tubaeform runner that internal diameter increases gradually advancing to form one section flow channel for liquids between the glue position for irritating mouth 2 to glue-feeder from hot flow path.
The longitudinal section of described slide block 5 internal cavities is a parallelogram, and the inclined plane of cavity is parallel with the axis of Angle Pin 4.
Concrete motion process of the present invention is as follows:
After advancing glue and finishing, the mould die sinking, product 7 and stub bar (the A part among Fig. 2) are stayed the male model side, as shown in Figure 1, because the lateral surface in Angle Pin 4 and slide block 5 holes has a segment distance, in a segment distance of die sinking just, Angle Pin 4 can not push slide block, and slide block 5 does not move, and continues die sinking, after the stub bar of glue-feeder is deviate from mother module core 3, when pushing slide block 5, as shown in Figure 2, slide block 5 setting in motions, this moment, stub bar broke away from mother module core 3, and slide block 5 can normally withdraw from.Along with die sinking continues, slide block 5 continues extrapolated under the stirring of Angle Pin 4, finishes until die sinking, as shown in Figure 3.
