Abstract

The utility model provides a built-in mechanical double ejection mechanism, comprising an upper ejection plate, an upper bottom plate, a lower ejection plate, a lower bottom plate, a bushing, an elastic ejection rod and a guide bar, wherein the bushing, the elastic ejection rod and the guide bar are cooperatively connected to form a double ejection mechanism; the upper ejection plate and the upper bottom plate are cooperatively connected to form a first through hole for accommodating one end of the double ejection mechanism; the lower ejection plate and the lower bottom plate are cooperatively connected to form a second through hole for accommodating the other end of the double ejection mechanism; and the double ejection mechanism penetrates into the first through hole and the second through hole. The built-in mechanical double ejection mechanism provided by the utility model has the advantages of simple structure, low processing cost, small occupied space, convenience in disassembly and assembly and high accuracy.

Description

A kind of built-in mechanical type secondary ejection mechanism

Technical field

The utility model relates to mould applications, refers to especially a kind of built-in mechanical type secondary ejection mechanism.

Background technology

All the time, in the design and manufacture process of plastic, often there will be the recessed or plagioclase hole of side.Because side is recessed or plagioclase hole different from die sinking direction (vertical or angled), plastic can not direct demold, therefore must Element Design moulding side is recessed or plagioclase hole become mobilizable in mould structure design, be called moving core, before the plastic demoulding, must first carry out undercut, moving core is extracted out, and plastic can the demoulding, and complete this moving core, takes out the mechanism of mountain and reset and is called oblique core-pulling mechanism.Conventionally, the mode of loosing core of oblique slotted hole is rack-and-pinion pulled core structure, though this mechanism can meet the production requirement of such part, along with day by day improving and the raising day by day of labor productivity product appearance quality requirement.

Utility model content

The deficiency existing for prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, at the bottom of processing cost, take up room little, easy accessibility and high-precision built-in mechanical type secondary ejection mechanism.

The technical solution of the utility model is achieved in that a kind of built-in mechanical type secondary ejection mechanism, comprises upper plate, upper plate, lower roof plate, lower shoe, lining, elastic push rod and guide rod; Described lining, elastic push rod and guide rod are connected and form a secondary ejecting mechanism; Described upper plate and upper plate are connected and form the first through hole of placing secondary ejecting mechanism one end; Described lower roof plate and lower shoe are connected and form the second through hole of placing the secondary ejecting mechanism other end; Described secondary ejecting mechanism is applied in the first through hole and the second through hole.

Further, described elastic push rod is arranged in lining, described guide rod is arranged in elastic push rod.

A kind of built-in mechanical type secondary ejection of the present utility model mechanism, simple in structure, at the bottom of processing cost, take up room little, easy accessibility and high accuracy.

Accompanying drawing explanation

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 skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the package assembly schematic diagram of a kind of built-in mechanical type secondary ejection of the utility model mechanism;

Fig. 2 is the package assembly schematic diagram ejecting for the first time of a kind of built-in mechanical type secondary ejection of the utility model mechanism;

Fig. 3 is the package assembly schematic diagram ejecting for the second time of a kind of built-in mechanical type secondary ejection of the utility model mechanism.

The specific embodiment

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, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills 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-Figure 3: a kind of built-in mechanical type secondary ejection mechanism, comprises upper plate 1, upper plate 2, lower roof plate 3, lower shoe 4 and secondary ejecting mechanism (in figure, not indicating); Described upper plate 1 and upper plate 2 are connected, and form the first through hole 8 of secondary ejecting mechanism (not indicating in figure); Described lower roof plate 3 and lower shoe 4 are connected, and form the second through hole 9 of secondary ejecting mechanism (not indicating in figure); Described secondary ejecting mechanism (not indicating in figure) is applied in the first through hole 8 and the second through hole 9, described the first through hole 8 and the second through hole 9 are corresponding, and described the first through hole 8 and the second through hole 9 are designed to install the space of secondary ejecting mechanism (not indicating in figure).

Above-mentioned a kind of built-in mechanical type secondary ejection mechanism, described secondary ejecting mechanism (not indicating in figure) comprise lining 5, elastic push rod 6 and guide rod 7; Described elastic push rod 6 is arranged in lining 5, and described guide rod 7 is arranged in elastic push rod 6.

Operation principle: a kind of built-in mechanical type secondary ejection mechanism utilizes the reducible principle of elastic push rod 6 head to realize Double-ejection.As shown in Figure 2; The ejecting force that lining 5 is subject to elastic push rod 6 when ejecting for the first time makes upper plate 1 part and lower roof plate 3 parts eject S1 simultaneously, and now guide rod 7 heads are separated with elastic push rod 6, and elastic push rod 6 heads dwindle.As shown in Figure 3: now eject for the second time, so the lining 5 of upper plate 1 part due to now motionless without ejecting force, lower roof plate 3 continues upwards to eject S2

The foregoing is only preferred embodiment of the present utility model and oneself; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
