Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, the utility model provides a kind of tubing mould, this structure is note laminated structure, for making the note compacting of pipe, it is provided with runner plate 1 from top to bottom successively, cope match-plate pattern 2, core rod assembly 3, lower bolster 4 and lower bolster 5, wherein core rod assembly 3 as shown in Figure 3, comprise crossbeam 31, the center of crossbeam 31 is provided with rotating shaft 32, rotating shaft 32 bilateral symmetry is provided with the big mould core 33 be fixed on crossbeam 31, the outside of big mould core 33 is provided with and is movably connected on crossbeam 31 and rotatable small mould core 34, big mould core 33 and small mould core 34 all can rotate around rotating shaft 32, wherein small mould core 34 activity is plugged on the sidewall of big mould core 33, the sidewall of big mould core 33 is provided with interface 331, termination 341 activity of small mould core 34 is plugged on interface 331, when carrying out pressure injection, the termination 341 of small mould core 34 is plugged on the interface 331 of big mould core 33, during the demoulding, then the termination 341 of small mould core 34 is pulled out.
Product just can be gone out after general sulfidization molding such as rubber product such as grade, and vulcanizing press is in idle condition when going out product, the rubber product sulfuration production time with go out the product time and do not have overlapping, because there is flexible and buffering ripple feature the general middle part of pipe series products, also existence that is flexible and buffering ripple is had when designing core rod, thus its cure time and the assisted demoulding time all long, cause production efficiency extremely low, and it is large by adopting, small mould core and around the symmetrically arranged structure of rotating shaft 32, the demoulding of product can be carried out while sulfuration is produced, save the stand-by period of vulcanizing press during product stripping, production efficiency is doubled, benefit is considerable.
Cope match-plate pattern 2 and lower bolster 4 are also connected with small mould core guide finger 6, it is through cope match-plate pattern 2 and lower bolster 4, be convenient to the grafting of small mould core 34, the upper end of small mould core guide finger 34 is oblique cone platform shape, as shown in Figure 4, the reason adopting oblique cone platform shape is when the termination 341 of small mould core 34 can be made to extract from interface 331, can be lifted by oblique cone platform structure, and the termination 341 of small mould core 34 also can be made afterwards to playback fast and accurately, be plugged on interface 331, there will not be the phenomenon of bite, pressing mold.
Die cavity and runner 7 is formed after cope match-plate pattern 2 and lower bolster 4 fit, wherein die cavity accommodates big mould core 33 and small mould core 34, and then realize the injection moulding of whole product, in the present embodiment, runner 7 is Y-shaped and be communicated in this die cavity, why be arranged to Y shape, be because the flow velocity of sizing material can be slowed down, avoid sizing material directly to die center, generation side is stressed, the phenomenon that the became uneven finally causing occurring product is even; The bifurcated of runner 7 extends to the ripple place of big mould core 33 simultaneously, when carrying out note pressure, contributes to the flow velocity slowing down sizing material further, prevents the instantaneous pressurized of core rod, occurs damaging.
Runner plate 1 being provided with main cast gate 11, for being communicated with runner 7, realizing the process of whole injection moulding.
As shown in Figure 5, lower bolster 4 is provided with band hopper 41, is positioned at the initiating terminal of runner 7, it is corresponding with the position of the main cast gate 11 of runner plate 1, band hopper 41 is communicated in runner 7 equally, and its shape can be designed to circle and have to retrodict pull out, on the one hand in order to slow down the flow velocity of sizing material; On the other hand waste material is stayed on lower bolster 4, facilitate the process of waste material.
In the present embodiment, runner plate 1, cope match-plate pattern 2, core rod assembly 3, lower bolster 4 and lower bolster 5 are fixed together by long guide pillar 8, realize the firm of whole mould structure;
Rotating shaft 32 two ends are provided with cylinder roller bearing, and this cylinder roller bearing is arranged on to be lifted in film frame fixed block 9, facilitates the rotation of rotating shaft 32.
The present embodiment can also arrange position block at the two ends of crossbeam 31, during for injection moulding, to the rotation of two groups of core rods, and then realize one group carry out sulfuration production while, another group carries out demoulding work.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
