Abstract
The utility model provides a synchronous pull rod mechanism for secondarily ejecting a mould. The synchronous pull rod mechanism comprises a mould B plate, a top plate, a base plate, a light load spring, a pull rod and an inner hexagon screw, wherein through holes for placing the synchronous pull rod mechanism are formed in the mould B plate, the top plate and the base plate; the synchronous pull rod mechanism is formed by connecting the light load spring, the pull rod and the inner hexagon screw; the light load spring is arranged at the outer side of the pull rod, and a screw hole for connecting the inner hexagon screw is formed in the lower end of the pull rod. The synchronous pull rod mechanism for secondarily ejecting the mould has the advantages of simple structure, low processing cost, small occupied space, convenience in disassembly and strong practicality.
Description
Technical field
The utility model relates to mould applications, refers to especially a kind of Synchronous pull rod mechanism for secondary ejection mold.
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, and processing cost is low, it is little to take up room, convenient disassembly and the practical Synchronous pull rod mechanism for secondary ejection mold.
The technical solution of the utility model is achieved in that a kind of Synchronous pull rod mechanism for secondary ejection mold, comprises mould B plate, top board, backing plate, underload spring, pull bar and hexagon socket head cap screw; In described mould B plate, top board and backing plate, be provided with the through hole of placing Synchronous pull rod mechanism; Described Synchronous pull rod mechanism is connected and composed by underload spring, pull bar and hexagon socket head cap screw, and described underload spring is arranged on the outside of pull bar, and pull bar lower end is provided with the screw that connects hexagon socket head cap screw.
Further, the described Synchronous pull rod mechanism for secondary ejection mold also comprises top rod; Described top rod is arranged on top board and backing plate cooperation place.
Further, described through hole comprises mould B plate through hole, top board through hole and backing plate through hole; Described pull bar and underload spring are connected and are arranged in mould B plate through hole, and described pull bar and hexagon socket head cap screw run through and be arranged in top board through hole and backing plate through hole.
Further, described a kind of Synchronous pull rod mechanism for secondary ejection mold also comprises elastomeric pad; Described elastomeric pad is arranged on the cooperation place of pull bar and hexagon socket head cap screw.
A kind of Synchronous pull rod mechanism for secondary ejection mold of the present utility model, simple in structure, processing cost is low, little, convenient disassembly and practical takes up room.
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 sectional structure schematic diagram of a kind of Synchronous pull rod mechanism for secondary ejection mold of the utility model.
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: a kind of Synchronous pull rod mechanism for secondary ejection mold, comprises mould B plate 1, top board 2, backing plate 3, underload spring 5, pull bar 4 and hexagon socket head cap screw 6; In described mould B plate 1, top board 2 and backing plate 3, be provided with the through hole of placing Synchronous pull rod mechanism; Described Synchronous pull rod mechanism is connected and composed by underload spring 5, pull bar 4 and hexagon socket head cap screw 6, and described underload spring 5 is arranged on the outside of pull bar 4, and pull bar 4 lower ends are provided with the screw (in figure without indicating) that connects hexagon socket head cap screw 6.
Above-mentioned a kind of Synchronous pull rod mechanism for secondary ejection mold, the described Synchronous pull rod mechanism for secondary ejection mold also comprise top rod 7; Described top rod 7 is arranged on top board 2 and backing plate 3 cooperation places.
Above-mentioned a kind of Synchronous pull rod mechanism for secondary ejection mold, described through hole comprise mould B plate through hole (figure does not indicate), top board through hole 21 and backing plate through hole 31; Described pull bar 4 and underload spring 5 are connected and are arranged in mould B plate through hole (not indicating in figure), described mould B plate through hole (not indicating in figure) comprises pull bar through hole 12 and underload spring through hole 11, in one end pull bar through hole 12 of described pull bar 4, described underload spring 5 is arranged in underload spring through hole 11; Described pull bar 4 and hexagon socket head cap screw 6 run through and are arranged in top board through hole 21 and backing plate through hole 31.
Above-mentioned a kind of Synchronous pull rod mechanism for secondary ejection mold, described a kind of Synchronous pull rod mechanism for secondary ejection mold also comprise elastomeric pad 8; Described elastomeric pad 8 is arranged on the cooperation place of pull bar 4 and hexagon socket head cap screw 6.
Operation principle: a kind of Synchronous pull rod mechanism for secondary ejection mold is fixed on template B plate 1, develop the bottom surface of pull bar 4 hanging platforms and top board 2, when template B plate 1 moves up, top board 2 can move up simultaneously, template B plate 1 move up stop after a segment distance mobile, now top board 2 still can continue upwards to eject by injection machine top rod 7, and now mould B plate 1 is motionless, and so just can realize the object of Double-ejection
A kind of Synchronous pull rod mechanism for secondary ejection mold of the present utility model, simple in structure, processing cost is low, little, convenient disassembly and practical takes up room.
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.
