Description
Technical field
The utility model relates to technical field of mold, particularly a kind of core-pulling die structure of elongated tubular bodies.
Background technology
In recent years, powerful gradually along with the plastic mould of micron order, the output of plastic products is increasing, and required precision is also more and more higher, and particularly the mould of plastics of medical industries requires more and more higher.The plastic mould that is used for producing plasthetics is indispensable important component part in the whole production process of plasthetics, and the structure of mould has direct impact to product quality and production process.While adopting injection mold to manufacture the elongated tubular bodies of medical industry, before the demoulding, need the core of moulding tube chamber to loose core, traditional method adopts loose core of oil cylinder more, but loose core of oil cylinder has following shortcoming: (1) die sinking and matched moulds all want limited location switch to control, be generally first and open that (front and back mould die joint is first opened, shovel is got out of the way) after close (slide block first resets, and shovel is closed (otherwise mould breaks) again) and control complicatedly, molding cycle is long; (2) there are oil pollution and easy care not; (3) forming machine will have special neutron to control, and requires also high to forming machine.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of mould core pulling mechanism of elongated tubular bodies.The mould core pulling mechanism molding cycle of this elongated tubular bodies is short, low without greasy dirt and maintenance cost, without forming machine, controls slide block folding, and utilizes the combination of the curved pin of Angle Pin and side to loose core, and Angle Pin can the bending because of being subject to compared with large enclasping force.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of core-pulling die structure of elongated tubular bodies, comprise solid plate, moving platen, slide block, the curved pin of Angle Pin and side, on solid plate and moving platen, be equipped with die cavity, between the die cavity of solid plate and the die cavity of moving platen, form die cavity, described slide block is slidably arranged in the die cavity of described moving platen, in die cavity, be provided with core, this core is connected with described slide block, described slide block is provided with slanting guide pillar hole, Angle Pin inserts in the slanting guide pillar hole of described slide block, the upper end of Angle Pin is connected with solid plate, described slide block be each side provided with a skewed slot, in each skewed slot, be provided with the curved pin of a side, the curved pin of the party partly consists of skewback part and vertical blocks, wherein, the skewback of the curved pin of each side is partly positioned at corresponding skewed slot, the vertical blocks part of the curved pin of each side is fixedly connected with described solid plate.
Further, the outside of described slide block is inclined-plane, on the die cavity sidewall of described solid plate, is also provided with inclined-plane, and the inclined-plane of die cavity sidewall and the inclined-plane of described slide block of this solid plate are adjacent to.
Further, be provided with a slide in the die cavity of described moving platen, described slide is provided with slide rail, and slide block and slide rail are slidably matched.
The beneficial effects of the utility model are: the utility model utilizes the cooperation of the curved pin of Angle Pin and side to loose core.For elongated tubular bodies, because resin is larger to the enclasping force of the whole core for moulding tube chamber, with Angle Pin, complete all and loose core separately, can make Angle Pin bending owing to being subject to compared with large enclasping force.The utility model is when die sinking, by the curved pin in side, first stir slide block, give initial force of slide block, overcome the enclasping force of resin, and then move by Angle Pin band movable slider, slide block drives core to extract out again, thereby it is easier to make to loose core, and Angle Pin can the bending owing to being subject to compared with large enclasping force yet.In addition, the utility model molding cycle is short, low without greasy dirt and maintenance cost, and controls slide block folding without forming machine.

The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1 to Figure 3, a kind of core-pulling die structure of elongated tubular bodies, comprise solid plate 1, moving platen 2, slide block 3, the curved pin 5 of Angle Pin 4 and side, on solid plate 1 and moving platen 2, be equipped with die cavity, between the die cavity of the die cavity of solid plate 1 and moving platen 2, form die cavity, described slide block 3 is slidably arranged in the die cavity of described moving platen 2.Concrete, in the present embodiment, in the die cavity of described moving platen 2, being provided with a slide 7, described slide 7 is provided with slide rail 8, and slide block 3 is slidably matched with slide rail 8.In die cavity, be provided with core 6, this core 6 is connected with described slide block 3, described slide block 3 is provided with slanting guide pillar hole, Angle Pin 4 inserts in the slanting guide pillar hole of described slide block 3, the upper end of Angle Pin 4 is connected with solid plate 1, described slide block 3 be each side provided with a skewed slot, in each skewed slot, be provided with the curved pin 5 of a side, the curved pin 5 of the party consists of skewback part 51 and vertical blocks part 52, wherein, the skewback part 51 of the curved pin 5 of each side is positioned at corresponding skewed slot, and the vertical blocks part 52 of the curved pin 5 of each side is fixedly connected with described solid plate 1.
In the present embodiment, the outside of described slide block 3 is inclined-plane, on the die cavity sidewall of described solid plate 1, is also provided with inclined-plane, and the inclined-plane of the die cavity sidewall of this solid plate 1 and the inclined-plane of described slide block 3 are adjacent to.
During matched moulds, between solid plate 1 and the die cavity of moving platen 2, form die cavity, core 6 is shifted to die cavity place, after injection mo(u)lding, when die sinking, moving platen 2 band movable sliders 3, core 6 and elongated tubular bodies start to move down, now, the curved pin 5 in side being fixed on solid plate 1 is first stirred slide block 3, gives 3 one initial forces of slide block, first overcome the enclasping force of casting resin, while continuing die sinking, Angle Pin 4 moves slide block 3, slide block 3 drives core 6 to extract out, leave goods, complete the action of loosing core, to carry out follow-up demoulding action.Whole, loose core in process, the curved pin 5 in side mainly plays and overcomes the effect of casting resin to the enclasping force of core, and Angle Pin 4 completes the moving process of core 6.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
