The specific embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
See also Fig. 2 and Fig. 3, the utility model injection mold comprise a master mold 10, tiltedly top mechanism 20 and one with the male model 30 of master mold 10 corresponding cooperations.
Said master mold 10 comprises a caster 11 and mother module core 12; This mother module core 12 comprises that one first mother module core 121 and an edge are placed in second mother module core 122 on first mother module core 121, and this first mother module core 121 is concaved with a storage tank (not indicating among the figure) and a receiving space 1211 from this storage tank mediad sunken inside.This second mother module core 122 just is contained in this storage tank, and offers one and run through resigning hole 1221 and two symmetries of these second mother module core, 122 centre and downward outward-dipping guide holes 1222 that are arranged at resigning hole 1221 both sides.This resigning hole 1221 and two guide holes 1222 all communicate with receiving space 1211.
Said oblique top mechanism 20 be positioned at mother module core 12 receiving space 1211 and can be up and down in receiving space 1211, this tiltedly pushes up the tilted footstock 21 and two that mechanism 20 comprises one " T " shape cross section and tiltedly pushes up 22.This tilted footstock 21 can be installed in the receiving space 1211 up and downly; It has an oblique top board 211 and is connected in a projection 212 at middle part, oblique top board 211 lower ends; This oblique top board 211 is provided with the guide rail (not indicating among the figure) of horizontal expansion; This projection 212 can be arranged in the resigning hole 1221 up and downly, offers a switching hole 2121 on the projection 212; Two tiltedly top 22 is all L-shaped for this; Have the forming part 221 that the angle ejector rod 222 that tilt to extend and outwards is convexly equipped with from angle ejector rod 222 lower outside respectively, an end of this angle ejector rod 222 passes guide hole 1222 and can on the direction vertical with the die sinking direction, be installed in slidably on the guide rail of oblique top board 211.
Said male model 30 is oppositely arranged with master mold 10; This male model 30 has male model plate 31 and male model benevolence 32; This male model benevolence 32 comprises that one first a male model benevolence 321 and an edge are placed in the second male model benevolence 322 on the first male model benevolence 321; Offer the accepting groove (not indicating among the figure) that caves inward on this first male model benevolence 321, this second male model benevolence 322 just is contained in this accepting groove, and this second male model benevolence 322 is provided with the shutter that forming part (not indicating among the figure) and matches with the switching hole 2121 of tilted footstock 21; Particularly, this shutter is a resin shutter 3221, and it is fixed on the second male model benevolence 322 through a fixture (not indicating among the figure).
See also Fig. 4-6, during matched moulds, the forming part 221 one common peripheral forming cavities on mother module core 12, male model benevolence 32 and oblique top 22 (indicating among the figure), resin shutter 3221 is placed in the switching hole 2121 of projection 212; During die sinking; Under the tension of resin shutter 3221; Master mold 10 relative male models 30 and tiltedly upwards separation of top mechanism 20; Be resisted against on second mother module core 122 until oblique top board 211, tilted footstock 21 keeps transfixions and guide hole 1222 moves up with master mold 10, thus make two tiltedly top 22 under the guiding of guide hole 1222, inwardly slide and withdraw from the barb 81 of product 80 along the guide rail direction of die sinking (promptly perpendicular to) respectively.Afterwards; Because shutter 3221 is fixed on the male model benevolence 32, the oblique top board 211 of tilted footstock 21 is fastened on second mother module core 122, by force resin shutter 3221 is pulled out from open and close hole 2121 along with the continuing to move up of master mold 10; Thereby die sinking fully, and then the demoulding of completion product 80.
In sum; The utility model injection mold is held tilted footstock 21 through resin shutter 3221 at the beginning of die sinking, so as the oblique top 22 of tilted footstock 21 can be under the guiding of guide hole 1222 respectively along inwardly slip and withdrawing from smoothly of the guide rail direction of die sinking (promptly perpendicular to) from the barb 81 of product 80; After this draw back this resin shutter 3221 by force, thereby accomplish product 80 demouldings; The utility model injection mold principle is simple, and is easy to make, is beneficial to and enhances productivity.
