Abstract
The utility model discloses a novel mold for adopting a spring thimble to replace an ejector sleeve. The novel mold comprises a base plate, a thimble base plate, a thimble panel, a guide pillar, a movable mold plate and a movable mold core, wherein the thimble panel is provided with an ordinary thimble and a spring thimble; two thimbles penetrate through the movable mold plate and the movable mold core to be connected with a product; the lower end of the spring thimble is of a step structure; the thimble panel is provided with the step structure corresponding to the spring thimble; the lower end of the spring thimble is fixedly connected with a reset spring; the novel mold also comprises a thimble limit rod; the thimble limit rod is arranged inside the reset spring; the lower end of the thimble limit rod is fixedly connected with a spring pressing plate; the lower end of the reset spring is fixedly connected with the spring pressing plate; the spring pressing plate is fixedly connected with the base plate through screw nails. The novel mold has the beneficial effects that the manufacturing cost of the mold is reduced and the production efficiency is greatly improved.
Description
Technical field
The utility model belongs to mould applications, particularly a kind of mould that adopts spring thimble to substitute ejector sleeve.
Background technology
Existing have circular through hole or a blind hole on a lot of products, the mould of this injecting products all will be used ejector sleeve; Ejector sleeve is that circular through hole or blind hole are arranged on product, and the glue position must arrange and ejects a kind of liftout attachment metal fittings that adopt.Ejector sleeve is comprised of two parts, ejector sleeve and interior pin; Ejector sleeve is enclosed within on interior pin, can move up and down; Interior pin is fixed on die bottom plate, and ejector sleeve is contained on ejector retainner plate, and when ejecting, ejector sleeve is along with moving on ejector retainner plate, and at this moment interior pin is because be fixed on die bottom plate, not mobile, thereby ejector sleeve will wrap in the upper product of interior pin, ejects.
And the wall thickness of some product circular hole is thinner, and corresponding ejector sleeve thickness is also thinner, flexible, the distortion and cracked of ejector sleeve while causing die sinking.
The utility model content
, distortion and cracked flexible for ejector sleeve in existing mold, the utility model provide a kind of novel die that does not need the employing spring thimble of ejector sleeve.
To achieve these goals, the utility model is that the technical scheme that its technical problem of solution is taked is:
a kind of novel die that adopts spring thimble to substitute ejector sleeve, comprise base plate, Ejector Retainer Plate, the thimble panel, guide pillar, moving platen and mavable module core, described thimble panel is provided with common thimble and spring thimble, two thimbles interted moving platen and were connected with product with mavable module core, described spring thimble lower end is a ledge structure, the thimble panel is provided with the ledge structure corresponding with spring thimble, the spring thimble lower end is connected with back-moving spring, also comprise the thimble gag lever post, the thimble gag lever post is located in back-moving spring, thimble gag lever post lower end is connected with spring bearer plate, back-moving spring lower end and spring bearer plate are affixed, spring bearer plate is fixed on base plate by screw.
The beneficial effects of the utility model: the utility model mould has utilized the reduction power principle of spring to promote the rising of thimble, realized easy secondary ejecting mechanism, be different from conventional Double Tops plate secondary top, fallen at the end cost of manufacture of mould, improved greatly production efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
a kind of novel die that adopts spring thimble to substitute ejector sleeve as shown in Figure 1, comprise base plate 10, Ejector Retainer Plate 9, thimble panel 11, guide pillar 12, moving platen 1 and mavable module core 2, described thimble panel 11 is provided with common thimble 5 and spring thimble 3, two thimbles interted moving platen 1 and were connected with product 4 with mavable module core 2, described spring thimble 3 lower ends are a ledge structure, thimble panel 11 is provided with the ledge structure corresponding with spring thimble 3, spring thimble 3 lower ends are connected with back-moving spring 6, also comprise thimble gag lever post 7, thimble gag lever post 7 is located in back-moving spring 6, thimble gag lever post 7 lower ends are connected with spring bearer plate 8, back-moving spring 6 lower ends and spring bearer plate 8 are affixed, spring bearer plate 8 is fixed on base plate 10 by screw.
Back-moving spring 6 promotes spring thimble 3 by elastic force when top board starts, when the step on spring thimble 3 rise to thimble panel 11 on the step collision time, spring thimble 3 no longer rises, at this moment the cylinder lateral wall of product 4 has broken away from mavable module core; And this moment, Ejector Retainer Plate 9 continued to rise with common thimble 5, promoted product 4 and broke away from spring thimble 3, and product 4 can be taken out smoothly.The utility model mould has utilized the reduction power principle of spring to promote the rising of thimble, has realized easy secondary ejecting mechanism, is different from conventional Double Tops plate secondary top, has fallen at the end cost of manufacture of mould, has improved greatly production efficiency.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
