Abstract

The utility model provides a forming mold for seven impellers of an automobile engine. In a mold opening process, a front mold plate and a rear mold plate are parted, a slanted guide pillar clamped in a guide slot drives a first rear mold slider to move to one side to complete the first parting; after the first rear mold slider moves by a certain distance, the slanted guide pillar drives a second rear mold slider to move to complete the second parting; then, under the action of an oil cylinder, a base plate and the rear mold plate are parted, a rhomb fixed on the base plate drives a third rear mold slider to move to one side so as to complete the third parting; and finally the product is ejected out of a rear mold cavity through an ejector pin and automatically falls. Through the design of the forming mold for seven impellers of the automobile engine, an insert of the mold does not need to be manually stripped during the forming process, so that the automatic injection molding production can be realized, the time of injection molding design can be shortened, the productivity can be increased, the formed product does not need post-processing and the cost can be lowered.

Description

The mould of seven impellers in automobile engine

Technical field

The utility model relates to the mould of seven impellers in a kind of automobile engine.

At present, seven impellers on market in common automobile engine are cast aluminium or plastic cement material, and seven impellers of cast aluminium material also need processing after moulding, and cost is high; And seven impellers of plastic cement material need manually be peeled off inlaid piece of mould, cannot realize automated production.

Given this, be necessary to design the mould of seven impellers in a kind of new automobile engine, to overcome defect of the prior art.

Utility model content

The purpose of this utility model is to overcome the defect of prior art, and providing does not need reprocessing after a kind of moulding and without the mould of manually peeling off seven impellers in the automobile engine of inlaid piece of mould.

The utility model is achieved in that the mould of seven impellers in a kind of automobile engine, comprises; One front template, is tabular, which is provided with cast passage, and offers thereon a guiding groove, and guiding groove is pre-large post-small; One rear pattern plate, is tabular, is positioned at the rear of described front template, contacts with described front template; One backing plate, is tabular, is positioned at the rear of described rear pattern plate, contacts with described rear pattern plate; One Angle Pin, pre-large post-small, part is positioned at described guiding groove, is resisted against described guiding groove; One first rear mode slider, offers one first storage tank on it, described Angle Pin enters wherein from described guiding groove; One second rear mode slider, offers one second storage tank on it, described Angle Pin enters wherein through described guiding groove and described the first storage tank; One the 3rd rear mode slider, offers one the 3rd storage tank and the 4th storage tank on it, described Angle Pin enters in described the 3rd storage tank; One is tiltedly square, is fixed on described backing plate, and described oblique side enters described the 4th storage tank; One oil cylinder, is positioned at described backing plate below; In die sinking process; described front template and described rear pattern plate somatotype; the Angle Pin being stuck in described guiding groove drives described the first rear mode slider lateral movement; complete somatotype for the first time; when after described the first rear mold slide block movement certain distance; described Angle Pin drives described the second rear mold slide block movement; complete somatotype for the second time; then again under oil cylinder effect; described backing plate and described rear pattern plate somatotype, the oblique side who is fixed on described backing plate stirs described the 3rd rear mode slider lateral movement, completes somatotype for the third time; final product ejects rear model cavity, Automatic-falling by thimble.

The utility model provides the mould of seven impellers in a kind of automobile engine, slider designs is become to three sections, comprise the first rear mode slider, the second rear mode slider and the 3rd rear mode slider, and described the first rear mode slider and described the second rear mode slider can be separated with product by described Angle Pin, also can described the 3rd rear mode slider can be separated with product by described oblique side's drive, without the mold insert of manually peeling off mould, realize automatic injection production, shorten injection moulding design, promote production capacity, and after formed product without rear processing, reduce costs.

Brief description of the drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The structural representation of the mould of seven impellers of automobile engine that Fig. 1 provides for the utility model embodiment;

Fig. 2 is the structural representation of three sections of somatotype slide blocks in the utility model embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1 to Figure 2, in the utility model automobile engine, the mould of seven impellers adopts three sections of somatotype slider designs, comprises a front template 1, be tabular, which is provided with cast passage (not indicating), and offer thereon a guiding groove 10, described guiding groove 10 is pre-large post-small, one rear pattern plate 2, is tabular, is positioned at the rear of described front template 1, contacts with described front template 1, one backing plate 3, is tabular, is positioned at the rear of described rear pattern plate 2, contacts with described rear pattern plate 2, one Angle Pin 4, pre-large post-small, part is positioned at described guiding groove 10, is resisted against described guiding groove 10, can in described guiding groove 10, not drop, and can be with the motion campaign of described front template 1, seven the first rear mode sliders 5, offer one first storage tank 50 on it, described Angle Pin 4 enters wherein from described guiding groove 10, seven the second rear mode sliders 6, are positioned at the rear of described the first rear mode slider, offer one second storage tank 60 on it, and described Angle Pin 4 enters wherein through described guiding groove 10 and described the first storage tank 50, seven the 3rd rear mode sliders 7, offer one the 3rd storage tank 70 and one the 4th storage tank 71 on it, described Angle Pin 4 enters in described the 3rd storage tank 70, seven oblique sides 8, are fixed on described backing plate 3, and described oblique side 8 enters described the 4th storage tank 71, one oil cylinder 9, is positioned at the below of described backing plate 3, in die sinking process, described front template 1 and described rear pattern plate 1 somatotype, the Angle Pin 4 being stuck in described guiding groove 10 drives described the first rear mode slider 5 lateral movements, complete somatotype for the first time, after described first after mode slider 5 motion certain distances, described Angle Pin 4 drives described the second rear mode slider 6 to move, complete somatotype for the second time, then under described oil cylinder effect, described backing plate 3 and described rear pattern plate 2 somatotypes, the described oblique side 8 who is fixed on described backing plate 3 stirs described the 3rd rear mode slider 7 lateral movements, complete somatotype for the third time, final product ejects die cavity by thimble, Automatic-falling.
