Description
Technical field
The utility model relates to a kind of injection forming mold, specifically refers to a kind of line position secondary core extracting mechanism.
Background technology
In the known prior art of injection mould structure, when there is projection external screw thread back-off the side of plastic products, by common thread-relieving mechanism, need first to play the steel position that A plate is left below projection, then deviate from screw thread by hydraulic jack band carry-over bar linked gear and thread core, mould structure meeting more complicated, mould volume is large, associated components increasing number, and the procedure of processing of parts is various, precise requirements is higher, and assembly difficulty is large.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of multiple line position secondary core extracting mechanism combined of loosing core, thus reduce assembly difficulty and simplify mould structure, and reduce mould volume.
The purpose of this utility model is achieved through the following technical solutions:
A kind of line position secondary core extracting mechanism, comprise Angle Pin, large line position slide block, secondary line position slide block and little line position slide block, described large line position slide block is provided with and wears for Angle Pin the first guide pillar hole be nested with, described secondary line position slide block is provided with and wears the second sliding guide pillar hole for Angle Pin, and between the first guide pillar hole on large line position slide block and Angle Pin, there is one section of empty avoiding gap, described secondary line position skid is engaged on large line position slide block, one end of described secondary line position slide block is provided with T-slot, outward extending thread core line position pin is installed with in described T-slot, described little line position slide block is provided with the T-shaped block structure be slidably matched with T-slot.
Further, described large line position slide block is provided with the sliding tray slided for secondary line position slide block thereon, and the left and right sides of described secondary line position slide block is provided with spacer pin, is provided with the spacing push rod corresponding with spacer pin position in described sliding tray.
Preferably, described spacer pin is fixed on secondary line position slide block by a briquetting, is connected with a flexible restoring organ at relative limit pin away from the side of spacing push rod.
The utility model has the following advantages and beneficial effect compared to existing technology:
The utility model first drives secondary line position slide block to walk back by Angle Pin, because secondary line position slide block and little line position slide block are T-shaped being slidably connected, secondary line position slide block when walking back little line position slide block by T-shaped be slidably connected to force move down, deviate from the back-off of thread core line position pin; Until Angle Pin touches large line position slide block, large line position slide block walks out stroke, and whole dropout process does line position secondary pulling mechanism, compared to prior art, eliminate hydraulic jack and drive taking of rack pinion structure space, reduce mould volume, decrease mechanism part quantity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the present embodiment provides a kind of line position secondary core extracting mechanism, comprise Angle Pin 1, large line position slide block 2, secondary line position slide block 3 and little line position slide block 4, described large line position slide block 2 is provided with and wears for Angle Pin 1 the first guide pillar hole be nested with, described secondary line position slide block 3 is provided with and wears the second sliding guide pillar hole 5 for Angle Pin 1, and between the first guide pillar hole on large line position slide block 2 and Angle Pin 1, there is one section of empty avoiding gap, described secondary line position slide block 3 is slidably fitted on large line position slide block 2, one end of described secondary line position slide block 3 is provided with T-slot, outward extending thread core line position pin 6 is installed with in described T-slot, described little line position slide block 4 is provided with the T-shaped block structure be slidably matched with T-slot.
Bad product is drawn in order to avoid avoiding, ensure sequential code system, the stroke of secondary line position slide block 3 need be limited, described large line position slide block 2 is provided with the sliding tray slided for secondary line position slide block 3 thereon, the left and right sides of described secondary line position slide block 3 is provided with spacer pin 7, is provided with the spacing push rod 8 corresponding with spacer pin position in described sliding tray.
Preferably, described spacer pin 7 is fixed on secondary line position slide block 3 by a briquetting 9, is connected with a flexible restoring organ 10 at spacer pin 7 away from the side of spacing push rod.In this enforcement, described flexible restoring organ adopts spring to realize, and one end of spring is connected on spacer pin 7, and the other end is connected on large line position slide block 2, thus is all be fixed on same position after guaranteeing the die sinking of secondary line position slide block 3.
Operation principle of the present utility model is as follows:
After mould die sinking, large line position slide block 2 is motionless, Angle Pin 1 drives secondary line position slide block 3 to walk back 14mm, because secondary line position slide block 3 and little line position slide block 4 are T-shaped being slidably connected, so secondary line position slide block 3 is walked back during 14mm little line position slide block 4 by T-shaped be slidably connected to force move down 3.75mm, deviate from the back-off of thread core line position pin, until Angle Pin 1 touches large line position slide block 2, large line position slide block 2 walks out stroke.
The utility model adopts line position secondary core extracting mechanism successfully can solve plastic products side projection external screw thread back-off, and structure is simple, and by force practical, parts are few, and arrangement space takies little, greatly reduce mould volume.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
