Description
Technical field
The utility model relates to technical field of mold, particularly relates to the injection mold that a kind of thimble ejects.
Background technology
Die ejector pin is for goods shaping in ejection die, traditional die ejector pin is the cylinder push rod that an external diameter is equal, cylindrical, top shank is provided with cylindrical thimble countersunk head, the die ejector pin of this structure is installed in a mold in die ejector pin installing hole, when needs eject moulded products, the thimble rod of die ejector pin stretches out in installing hole, moulded products is ejected, therefore there is following defect in the die ejector pin of this structure, whole thimble rod contacts with installing hole inner surface, when thimble rod moves back and forth, rub with installing hole inner surface, thus cause thimble rod outer surface to grind flower, thimble rod outer surface is made to become coarse, and make thimble rod surface wear, substantially reduce the service life of die ejector pin.
Utility model content
The purpose of this utility model is overcome the deficiency existed in background technology, the purpose of this utility model be propose a kind ofly to install firmly, the injection mold ejected with thimble of long service life.
For achieving the above object, the utility model adopts following scheme:
The injection mold that a kind of thimble ejects, comprise fixed half and moving half, cover half comprises A plate, panel and apparatus for pouring, dynamic model comprises B plate, ejecting mechanism, mould pin and base plate, described panel is fixed on A plate, apparatus for pouring is arranged in panel, described mould pin is arranged on base plate, B plate is arranged on mould pin, A plate is provided with die cavity, B plate is provided with core, described A plate and B plate are respectively arranged with cooling device, B plate and base plate support formation cavity by mould pin, ejecting mechanism is placed in cavity, the height of cavity is greater than the maximum height of core, ejecting mechanism comprises liftout plate and release link, release link is fixed on liftout plate, liftout plate is provided with many thimbles, this thimble runs through core and is fixedly connected with liftout plate, described thimble comprises pin and lower pin, one end of lower pin is fixedly connected with liftout plate, the other end of lower pin is connected with upper pin, upper pin and lower pin are all cylinder, lower pin and upper pin junction are provided with round platform, the bottom surface of round platform is connected with lower pin, the upper bottom surface of round platform is connected with upper pin, lower pin and upper pin are on same central axis, and the diameter ratio of lower pin and upper pin is 1.2-1.3.
In the injection mold that above-mentioned a kind of thimble ejects, the length of thimble is ejecting a little to the vertical range of liftout plate on thimble and core.
In the injection mold that above-mentioned a kind of thimble ejects, the lenth ratio of described lower pin and thimble is 0.6-0.7.
In the injection mold that above-mentioned a kind of thimble ejects, described upper pin and lower pin one-body molded, the top of upper pin is sphere.
In the injection mold that above-mentioned a kind of thimble ejects, described cooling device is multiple independently cooling water pipes, and cooling water pipe is evenly distributed on around core and die cavity.
The beneficial effects of the utility model are: the utility model is provided with cooling device by distribution on A plate and B plate, can cool the product between core and die cavity; Ejecting mechanism moves in cavity, thus by thimble the ejecting product on ejecting mechanism; The height of cavity is greater than the maximum height of core, effectively could eject like this to product.Arrange thimble to form by two sections, and the diameter of lower pin is greater than the diameter of pin, and the diameter ratio limiting lower pin and upper pin is 1.2-1.3, when lower pin diameter is determined, the less diameter then going up pin of this ratio follows the diameter of lower pin similar substantially, cannot avoid the wearing and tearing of pin; And this ratio is larger, the diameter of upper pin is less, too little stable not even cannot effective ejecting product, thimble can be made more stable so limit this ratio range, increase its service life.Be set to sphere by the top of upper pin, sphere and product contact surface few, thus reduce thimble on the impact of product appearance.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is Local map of the present utility model.
Cover half 1, dynamic model 2, A plate 11, panel 12, apparatus for pouring 13, B plate 21, ejecting mechanism 22, mould pin 23, base plate 24, cooling device 3, cavity 4, liftout plate 5, release link 6, thimble 7, upper pin 71, lower pin 72.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Referring to figs. 1 to Fig. 2, the injection mold that a kind of thimble ejects, comprise cover half 1 and dynamic model 2, cover half 1 comprises A plate 11, panel 12 and apparatus for pouring 13, dynamic model 2 comprises B plate 21, ejecting mechanism 22, mould pin 23 and base plate 24, described panel 12 is fixed on A plate 11, apparatus for pouring 13 is arranged in panel 12, described mould pin 23 is arranged on base plate 24, B plate 21 is arranged on mould pin 23, A plate 11 is provided with die cavity, B plate 21 is provided with core, described A plate 11 and B plate 21 are respectively arranged with cooling device 3, B plate 21 and base plate 24 support formation cavity 4 by mould pin 23, ejecting mechanism 22 is placed in cavity 4, the height of cavity 4 is greater than the maximum height of core, ejecting mechanism 22 comprises liftout plate 5 and release link 6, release link 6 is fixed on liftout plate 5, liftout plate 5 is provided with many thimbles 7, this thimble 7 runs through core and is fixedly connected with liftout plate 5, described thimble 7 comprises pin 71 and lower pin 72, one end of lower pin 72 is fixedly connected with liftout plate 5, the other end of lower pin 72 is connected with upper pin 71, upper pin 71 and lower pin 72 are all cylinder, lower pin 72 is provided with round platform with upper pin 71 junction, the bottom surface of round platform is connected with lower pin 72, the upper bottom surface of round platform is connected with upper pin 71, lower pin 72 and upper pin 71 are on same central axis, and lower pin 72 is 1.2-1.3 with the diameter ratio of upper pin 71.Wherein, on A plate 11 and B plate 21, distribution is provided with cooling device 3, can cool the product between core and die cavity; Ejecting mechanism 22 is mobile in cavity 4, thus ejecting by the thimble 7 pairs of products on ejecting mechanism 22; The height of cavity 4 is greater than the maximum height of core, effectively could eject like this to product.Arrange thimble 7 to form by two sections, and the diameter of lower pin 72 is greater than the diameter of pin 71, and the diameter ratio limiting lower pin 72 and upper pin 71 is 1.2-1.3, when lower pin 72 diameter is determined, the less diameter then going up pin 71 of this ratio follows the diameter of lower pin 72 similar substantially, cannot avoid the wearing and tearing of pin 71; And this ratio is larger, the diameter of upper pin 71 is less, too little stable not even cannot effective ejecting product, thimble 7 can be made more stable so limit this ratio range, increase its service life.
In above-mentioned, in order to more effective, stable ejecting product, the length of thimble 7 is thimble 7 and core ejects a little to the vertical range of liftout plate 5, and the lenth ratio of described lower pin 72 and thimble 7 is 0.6-0.7, limiting this ratio can make thimble 7 more firm, and holding capacity is better.Described cooling device 3 is multiple independently cooling water pipes, and cooling water pipe is evenly distributed on around core and die cavity.Described upper pin 71 is one-body molded with lower pin 72, and the top of upper pin 71 is sphere, and the top of upper pin 71 is set to sphere, and sphere is few with product contact surface, thus minimizing thimble 7 is on the impact of product appearance.
The foregoing is only preferred embodiment of the present utility model, is not restriction with the present embodiment, all make within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
