Abstract
The utility model relates to a thimble fixing device in an injection mold. The thimble fixing device comprises a front mold, a rear mold and a thimble for ejecting a product, wherein a mold cavity is formed after the front mold and the rear mold are assembled; the rear end of the front mold is fixedly connected with a front mold positioning block; the rear end of the rear mold is fixedly connected with a rear mold fixing block and a rear mold positioning block; the rear mold fixing block and the rear mold positioning block are fixedly connected by using a bolt; a thimble panel and a thimble base plate are arranged in the rear mold fixing block and are fixedly connected by using the bolt; the thimble is fixed in the thimble panel; and the head of the thimble extends into the mold cavity. The thimble fixing device is characterized in that a trapezoidal groove is formed on the thimble panel; a small panel is overlaid on the trapezoidal groove; a thimble hole is formed on the small panel; and the thimble passes through the thimble hole. The thimble panel for fixing the thimble is changed into a device formed by fastening the thimble panel and the small panel, so that the thimble can be replaced in due time. Therefore, the working time is saved, and the investment of raw materials of the mold is reduced.
Description
Technical field:
The utility model relates to a kind of injection mold, relates in particular to the interior thimble fixture of injection mold that can realize in good time changing thimble in a kind of injection mold.
Background technology:
Injection mold is to be applied in the injection machine of plastic product, comprise front mould, rear mold and thimble, the rear portion that is installed in injecting head that front mould and rear mold are vertical, the raw material of melting is injected in the die cavity of front mould and rear mold formation, after injection moulding is finished, by the thimble ejecting product, original thimble is to be fixed in the groove that the thimble panel offers, but when reality is used, according to the size of injecting products, thimble needs the artificial unloading to change, because the injection mold of itself is precision die, unloading process is comparatively loaded down with trivial details, the operating efficiency that impact is whole.
Summary of the invention:
The technical problem that the utility model solves provides a kind of saving mold materials and drops into, and is convenient for changing the interior thimble fixture of injection mold of thimble.
The technical scheme in the invention for solving the technical problem is: thimble fixture in a kind of injection mold, comprise front mould, rear mold and be used for the thimble of ejecting product, form die cavity behind described front mould and the rear mold matched moulds, the rear end of described front mould is fixedly connected with the front mould locating piece, the rear end of described rear mold is fixedly connected with rear mold fixed block and rear mold locating piece, described rear mold fixed block and rear mold locating piece are bolted to connection, in described rear mold fixed block, be provided with thimble panel and Ejector Retainer Plate, described thimble panel and Ejector Retainer Plate are bolted fixing, described thimble is fixed in the thimble panel, the head of this thimble extend in the die cavity, it is characterized in that: offer trapezoidal groove at described thimble panel, cover a small panel at this trapezoidal groove, offer centre hole in described small panel, described thimble passes this centre hole.
The beneficial effect of this device: this injection mold is installed on the injection machine, the raw material of melting is injected in the die cavity of front mould and rear mold formation, after injection moulding is finished, by the thimble ejecting product, according to actual conditions, the size of thimble needs to change in good time, and this device changes the thimble panel of original monomer into the combination of thimble panel and small panel, can make things convenient for the in good time replacing of thimble, improve operating efficiency.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of small panel in the utility model;
Fig. 3 is the left view of small panel in the utility model.
Among the figure: 1, front mould locating piece 2, front mould 3, die cavity 4, rear mold 5, thimble panel 6, Ejector Retainer Plate 7, rear mold fixed block 8, rear mold locating piece 9, thimble 10, small panel 11, centre hole.
The specific embodiment:
Thimble fixture in a kind of injection mold as shown in Figure 1, comprise front mould 2, rear mold 4 and be used for the thimble 9 of ejecting product, form die cavity 3 behind described front mould 2 and rear mold 4 matched moulds, the rear end of described front mould 2 is fixedly connected with front mould locating piece 1, the rear end of described rear mold 4 is fixedly connected with rear mold fixed block 7 and rear mold locating piece 8, described rear mold fixed block 7 and rear mold locating piece 8 are bolted to connection, in described rear mold fixed block 7, be provided with thimble panel 5 and Ejector Retainer Plate 6, described thimble panel 5 and Ejector Retainer Plate 6 are bolted fixing, described thimble 9 is fixed in the thimble panel 5, the head of this thimble 9 extend in the die cavity 3, offer trapezoidal groove at described thimble panel 5, cover a small panel 10 at this trapezoidal groove, offer centre hole 11 in described small panel 10, described thimble 9 passes this centre hole 11.
This injection mold is installed on the injection machine, the raw material of melting is injected in the die cavity 3 of front mould and rear mold formation, after injection moulding is finished, by thimble 9 ejecting products, according to actual conditions, the size of thimble 9 needs to change in good time, and this device changes the thimble panel 5 of original monomer into the combination of thimble panel 5 and small panel 10, can make things convenient for the in good time replacing of thimble, improve operating efficiency.
It is emphasized that, it more than is better implementation column of the present utility model, be not that the utility model is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
