Abstract

The utility model provides a preposed sliding block driving device. The preposed sliding block driving device comprises a front mould, a rear mould, a spring, a sliding block, a limited block, a link block and a depression bar, wherein the front mould and the rear mould are matched to form a sliding block driving device passage; the sliding block is clamped in the depression bar through the link block; and the spring and the limited block are matched and connected in the sliding block. Due to the design of the preposed sliding block driving device, the roll-out stroke of the sliding block is greatly reduced, the size of the mould is lowered, and the cost is saved.

Description

A kind of preposition slide-driving device

Technical field

The utility model relates to mould applications, refers to especially a kind of preposition slide-driving device.

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, but along with day by day improving and the raising day by day of labor productivity product appearance quality requirement, usually the flat tilted footstock using, general oblique top is directly connected with tilted footstock, the risk of easily pulling and killing in the time of use, and complex structure, processing cost is high.

Utility model content

The deficiency existing for prior art, it is a kind of by such design that the purpose of this utility model is to provide, and greatly reduced the stroke that skids off of slide block, reduced the volume of mould, saved the preposition slide-driving device of cost.

The technical solution of the utility model is achieved in that a kind of preposition slide-driving device, comprises front mould, rear mold, spring, slide block, limited block, contiguous block and press strip; After coordinating, described front mould and rear mold form a slide-driving device passage; Described slide block is connected in press strip by contiguous block; Described spring and limited block are connected and are arranged in slide block.

Further, in described rear mold, be provided with the through hole of placing press strip; Described press strip and contiguous block are connected and are arranged in rear mold through hole.

Further, on described front mould, be provided with the front mould through hole of placing spring.

A kind of preposition slide-driving device of the present utility model, by such design, has greatly reduced the stroke that skids off of slide block, has reduced the volume of mould, has saved cost.

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 Figure 1-Figure 4: a kind of preposition slide-driving device, comprises front mould 1, rear mold 2, spring 7, slide block 8, limited block 6, contiguous block 5 and press strip 4; After described front mould 1 and rear mold coordinate, form a slide-driving device passage (not indicating in figure), described mould 1 and rear mold 2 cooperations form a PL face 3; Described slide block 8 is connected in press strip 4 by contiguous block 5; Described spring 7 and limited block 6 are connected and are arranged in slide block 8.

In above-mentioned a kind of preposition slide-driving device, described rear mold 2, be provided with the rear mold through hole (not indicating in figure) of placing press strip 4; Described press strip 4 and contiguous block 5 are connected and are arranged in rear mold through hole (not indicating in figure).

On above-mentioned a kind of preposition slide-driving device, described front mould 1, be provided with the front mould through hole 9 of placing spring 7.

Operation principle: as shown in Figure 2: in matched moulds state, slide block 8 is connected in the press strip 4 that is arranged on rear mold 2 by contiguous block 5; As shown in Figure 3: in the time of die sinking, front mould 1 and rear mold 2 are opened, slide block 8 under the double reaction plus of press strip 4 and spring 7 to two side shiftings, when die sinking formation reaches S, the press strip 4 that is arranged on rear mold 2 is separated with contiguous block 5, and now, Slipper is still stayed in rear mold 2; As shown in Figure 4: when continuing die sinking, press strip 4 is separated with contiguous block 5, and under the position-limiting action of limited block 6, slide block 8 and rear mold 2 are separated.

A kind of preposition slide-driving device of the present utility model, by such design, has greatly reduced the stroke that skids off of slide block, has reduced the volume of mould, has saved cost.

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.
