Abstract
The utility model provides an external mechanical secondary ejection mechanism which comprises a mold plate A, a mold plate B, a mold plate C and an ejection device, wherein the mold plates (A, B and C) are connected with each other from the top to the bottom in a matched manner; the ejection device comprises a fixing seat, an elastic block device and an ejecting block; the elastic block device is matched with one end of the fixing seat, and is arranged on the mold plate A through the elastic block; the fixing seat is fixedly arranged on the mold plate B through a second bolt; one end of the ejecting block is arranged on the fixing seat; the other end of the ejecting block is fixedly arranged on the mold plate C through a third bolt. The external secondary ejection mechanism is simple in structure, low in processing cost, small in occupied area, convenient to disassemble, and high in stability.
Description
Technical field
The utility model relates to mould applications, refers to especially a kind of external mechanical formula secondary ejecting 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 Element Design recessed moulding side or plagioclase hole must be become to 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, takes out the mechanism of mountain and reset and is called oblique core-pulling mechanism and complete this moving core.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 the raising day by day to product appearance quality requirement and the raising day by day of labor productivity.
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, and processing cost is low, it is little to take up room, convenient disassembly and practical external mechanical formula secondary ejecting mechanism.
The technical solution of the utility model is achieved in that a kind of external mechanical formula secondary ejecting mechanism, mould A plate, mould B plate, mould C plate and liftout attachment; Described mould A plate, mould B plate and mould C plate are connected successively from top to bottom, and described liftout attachment comprises holder, plays block assembly and jacking block; Described bullet block assembly coordinates with one end of holder, and is arranged on mould A plate by bullet piece; Described holder is fixedly installed on mould B plate by the second bolt, and one end of described jacking block is arranged on holder, and the other end is fixedly installed on mould C plate by the 3rd bolt.
Further, described bullet block assembly also comprises spring; Described spring is arranged in bullet piece.
Further, on described holder, be provided with the chute of placing jacking block one end.
A kind of external mechanical formula secondary ejecting mechanism of the present utility model, simple in structure, processing cost is low, it is little to take up room, convenient disassembly and stability strong.
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 front view of a kind of external mechanical formula of the utility model secondary ejecting mechanism;
Fig. 2 is the closure state figure of a kind of external mechanical formula of the utility model secondary ejecting mechanism;
Fig. 3 is the figure of mold-opening structure for the first time of a kind of external mechanical formula of the utility model secondary ejecting 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.Based on the embodiment 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 Figure 1-Figure 5: a kind of external mechanical formula secondary ejecting mechanism, mould A plate 1, mould B plate 2, mould C plate 3 and liftout attachment (in figure, not indicating); Described mould A plate 2, mould B plate 3 and mould C plate 3 are connected successively from top to bottom, and described liftout attachment (not indicating in figure) comprises holder 4, bullet block assembly (not indicating in figure) and jacking block 5; Described bullet block assembly (not indicating in figure) coordinates with one end of holder 4, and is arranged on mould A plate by bullet piece 7; Described holder 4 is fixedly installed on mould B plate by the second bolt 41, and one end of described jacking block 5 is arranged on holder 4, and the other end is fixedly installed on mould C plate 3 by the 3rd bolt 51.
Above-mentioned a kind of external mechanical formula secondary ejecting mechanism, described bullet block assembly also comprise spring; Shown in spring be arranged in bullet piece.
On above-mentioned a kind of external mechanical formula secondary ejecting mechanism, described holder 4, be provided with the chute 42 of placing jacking block 5 one end.
Operation principle: when mould die sinking, when mould C plate moves up apart from S1, jacking block 5 separates with bullet piece 7, separate front because jacking block 5 withstands on bullet piece 7, therefore mould A plate 1 and mould C plate 3 distance of S1 that can simultaneously move up, mould C plate 3 continues to move up, mould A plate 1 is motionless 2, so just can realize sequential mold opening.
A kind of external mechanical formula secondary ejecting mechanism of the present utility model, simple in structure, processing cost is low, it is little to take up room, convenient disassembly and stability strong
The foregoing is only preferred embodiment of the present utility model; 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.
