Technical field
The utility model belongs to injection-moulding device field, particularly the flat thimble anti-rotation structure of one.
Background technology
De-molding injection molded products is last link in injection molding process, which determines the quality of final products, solidly product from mold ejection to ensure the yields of product.There is a kind of flat thimble in prior art, its push rod ejected by plastic product is platypelloid type, is mainly used in ejecting of plastic product web sections, is exactly the glue position of strip in addition, and when dome pin cannot put down, flat thimble is one and selects preferably.
But there is a problem in flat thimble: in injection moulding production process, machinery can produce vibrations, because flat thimble cup head is circular, the free degree that it rotates around Pivot Point Center cannot be limited, flat thimble can be unstable and rotate because of vibrations, and the thimble on injecting products can be caused like this to print the phenomenons such as the glue dislocation position of differing or on thimble.
Prior art adopts thimble panel to coordinate with Ejector Retainer Plate flat thimble is fixed, thimble panel has jogger hole and passes for push rod, and thimble cup head is pressed between thimble panel and Ejector Retainer Plate, flat thimble is fixed, but this kind of fixed form is along with the lengthening using the working time, and fixed effect is also undesirable.Therefore need the flat thimble fixed structure of finding out a kind of improvement, flat thimble can not be rotated.
Utility model content
The purpose of this utility model is to provide and a kind ofly flat thimble can be made to maintain static dynamic flat thimble anti-rotation combination.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of flat thimble anti-rotation structure, comprise thimble panel, Ejector Retainer Plate and flat thimble, flat thimble has thimble cup head and push rod, and thimble panel has jogger hole and passes for push rod, and thimble cup head is sandwiched in thimble panel and the flat thimble of Ejector Retainer Plate chien shih is fixed; Also be provided with location steel disc between thimble panel and Ejector Retainer Plate, location steel disc has non-circular anti-rotating hole; Thimble cup head is consistent with anti-rotating hole shape on the steel disc of location; Thimble cup head is placed in anti-rotating hole.
Wherein, locate steel disc and have multiple anti-rotating hole.
Further, locate steel disc and also have multiple circular port.
Further, the limit of anti-rotating hole and circular port has chamfering.
Wherein, anti-rotating hole is D shape hole, and thimble cup head is D shape thimble cup head.
Wherein, anti-rotating hole is mounting hole, and thimble cup head is kidney-shaped thimble cup head.
Compared with prior art, the flat thimble anti-rotation structure of one of the present utility model, which increase the location steel disc that a piece has non-circular anti-rotating hole, this steel plate is clipped in the middle of thimble panel and Ejector Retainer Plate, the cup head of flat thimble is also arranged to non-circular and is placed in anti-rotating hole, effectively can prevent the rotation of flat thimble like this.And this kind of Combined machining is simple, the anti-rotating hole on the steel disc of location can adopt the mode of stamping-out to obtain, and flat thimble can use conventional specification, just can coordinate with anti-rotating hole as long as carried out cutting by thimble cup head.The advantages such as it is simple that the utility model has structure, easy to process, with low cost, anti-rotation is effective.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
The flat thimble anti-rotation structure of one of the present utility model, as shown in Figure 2, it comprises thimble panel 3, Ejector Retainer Plate 4 and flat thimble 2.As shown in Figure 4, flat thimble 2 has thimble cup 21 and push rod 22.Thimble panel 3 has jogger hole for push rod 22 and passes, and thimble cup 21 is sandwiched in thimble panel 3 and the flat thimble 2 of Ejector Retainer Plate 4 chien shih is fixed.Between thimble panel 3 and Ejector Retainer Plate 4, be also provided with location steel disc 1, as shown in Figure 1, location steel disc 1 have non-circular anti-rotating hole 11; Thimble cup 21 is consistent with anti-rotating hole 11 shape on the steel disc 1 of location; Thimble cup 21 is placed in anti-rotating hole 11, just can limit the free degree that flat thimble 2 rotates around its axle center.The location steel disc 1 of this increase is placed in the middle of thimble panel 3 and Ejector Retainer Plate 4, and the thimble cup of flat thimble 2 21 is placed in the anti-rotating hole 11 on fixing steel plate, effectively can prevent the rotation of flat thimble 2 like this.And this kind of Combined machining is simple, the anti-rotating hole 11 on the steel disc 1 of location can adopt the mode of stamping-out to obtain, and flat thimble 2 can use conventional specification, just can coordinate with anti-rotating hole 11 as long as carried out cutting by thimble cup 21.
In the present embodiment, location steel disc 1 has multiple anti-rotating hole 11, multiple anti-rotating hole 11 in order to place multiple thimble cup 21, with the demand of satisfied complicated injecting products.Particularly, locate steel disc 1 and also have multiple circular port 12, in order to place common dome pin.More specifically, on the limit of anti-rotating hole 11 and circular port 12, also have chamfering in the present embodiment, the installation of flat thimble or dome pin can be facilitated.
In the present embodiment, as shown in Figure 3 and Figure 4, anti-rotating hole 11 is set to D shape hole, and the thimble cup corresponding with it 21 is also set to D shape.Thimble cup 21 handling ease of D shape, only need cut the sub-fraction of thimble cup 21, the anti-rotating hole 11 of D shape makes flat thimble 2 can only have a kind of setting angle, can not reverse.In addition, when run into flat thimble 2 eject head can 0 ° or 180 ° of two kinds of angles install time, anti-rotating hole 11 can be arranged to mounting hole, and thimble cup 21 is cut into kidney-shaped, and this kidney-shaped is shape remaining after circular symmetrical two ends cut a part symmetrically.In addition, anti-rotating hole can also be designed to the non-circular holes such as slotted eye, isosceles triangle hole, slot, and it all can play the effect of anti-rotation to flat thimble.
During this flat thimble anti-rotation combination assembling, first location steel disc 1 is installed on Ejector Retainer Plate 4, then flat thimble 2 and dome pin are installed in anti-rotating hole 11 and circular port 12, by push rod 22 through the jogger hole on thimble panel 3, finally thimble panel 3 and Ejector Retainer Plate 4 are locked, thimble cup 21 is secured in a press, thus completes the assembling of this combination.To sum up, the advantages such as it is simple that the utility model has structure, easy to process, with low cost, anti-rotation is effective.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
