Description
Technical field
The utility model relates to the liftout attachment in a kind of mould applications, is specifically related to a kind of unstressed trace liftout attachment.
Background technology
Liftout attachment has application more widely in current workpiece processing.Existing liftout attachment is mainly comprised of single push rod and mandrel plate, when Workpiece shaping, push rod can produce compression under powerful injection pressure, simultaneously because the length of push rod is longer again, the long deflection of push rod that also can cause of length can be larger, so workpiece will produce stress trace at its back side corresponding to push rod after moulding.This class stress trace can also be accepted reluctantly for the not high workpiece of some appearance requirement, but the workpiece that needs texture and minute surface etc. to have relatively high expectations to outward appearance for some surfaces, and it just becomes a place must avoiding in process.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of unstressed trace liftout attachment that can effectively eliminate surface of the work stress trace.
In order to achieve the above object, the technical solution of the utility model is as follows: unstressed trace liftout attachment, and it comprises:
Fixed head;
Mandrel plate, it is fixedly installed on this fixed head;
Male model plate, it is fixedly installed on this mandrel plate, on this male model plate, offers the first groove;
Die, it is arranged in this first groove, is provided with the processing stations for place work piece on this die;
Push rod, its bottom is installed on above-mentioned mandrel plate, and upwards successively through above-mentioned male model plate and die setting, the top of this push rod is also installed with at least one jacking block, and this jacking block exposes to above-mentioned processing stations and directly contacts with above-mentioned workpiece.
Further, offer one second groove on above-mentioned jacking block, the top of above-mentioned push rod is fixedly connected in this second groove.
The 13-17 of the height that further, the height of above-mentioned push rod is above-mentioned jacking block doubly.
Further, above-mentioned mandrel plate comprises upper ejector pin plate and the lower push rod plate setting gradually.
Further, on the surface that above-mentioned jacking block contacts with above-mentioned workpiece, be also matrix and be arranged with a plurality of the second jacking blocks.
Adopt the beneficial effect of technique scheme to be: the utility model is by being fixedly installed in the effect of at least one jacking block at push rod top, this jacking block directly contacts with workpiece, when Workpiece shaping, injection pressure can act on the die of jacking block and jacking block below, simultaneously because jacking block all will be significantly smaller than push rod on length and volume, make the decrement of himself bearing also less, so it compared with prior art, the workpiece of processing just can not produce stress trace at its back side after moulding, has guaranteed the complete and aesthetic property of workpiece outward appearance.
Accompanying drawing explanation
Fig. 1 is the structural representation of unstressed trace liftout attachment of the present utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Fig. 3 is the jacking block of unstressed trace liftout attachment of the present utility model structural representation under another kind of embodiment.
Wherein, 1. fixed head 2. mandrel plate 21. upper ejector pin plate 22. lower push rod plate 3. male model plate 31. first groove 4. die 41. processing stations 5. push rod 6. jacking block 61. second groove 62. second jacking block 7. workpiece.
The specific embodiment
Below in conjunction with accompanying drawing, describe preferred embodiment of the present utility model in detail.
In order to reach the purpose of this utility model, as shown in Figure 1-2, in a kind of embodiment of unstressed trace liftout attachment of the present utility model, it comprises: fixed head 1; Mandrel plate 2, it is by being spirally connected or other known ways are fixedly installed on this fixed head 1; Male model plate 3, it,, by being spirally connected or other known ways are fixedly installed on this mandrel plate 2, offers the first groove 31 on this male model plate 3; Die 4, it is arranged in this first groove 31, is provided with the processing stations 41 for place work piece 7 on this die 4; Push rod 5, its bottom is installed on mandrel plate 2, and upwards through male model plate 3 and die 4, arrange successively, the top of this push rod 5 is also by being spirally connected or other known ways are installed with a jacking block 6, and this jacking block 6 exposes to processing stations 41 and directly contacts with workpiece 7.This wherein, jacking block 6, except can being set to shown in figure, can also be set to a plurality of jacking blocks that stack arranges or is arranged side by side, and at this, will not enumerate.
In above-described embodiment, by being fixedly installed in the effect of at least one jacking block 6 at push rod 5 tops, this jacking block 6 directly contacts with workpiece 7, when workpiece 7 moulding, injection pressure can act on the die 4 of jacking block 6 and jacking block 6 belows, simultaneously because jacking block 6 all will be significantly smaller than push rod 5 on length and volume, make the decrement of himself bearing also less, so it compared with prior art, the workpiece 7 of processing just can not produce stress trace at its back side after moulding, has guaranteed the complete and aesthetic property of workpiece 7 outward appearances.
In order to optimize further implementation result of the present utility model, as shown in Figure 2, in the another kind of embodiment of unstressed trace liftout attachment of the present utility model, on the basis of aforementioned content, on above-mentioned jacking block 6, offer one second groove 62, the top of push rod 5 is by being spirally connected or other known ways are fixedly connected in this second groove 62.By the setting of the second groove 62, not only can also can dwindle further volume and the length of jacking block 6 so that the connection of jacking block 6 and push rod 5 is more firm, reduce further the impact on working stress trace.
In order to optimize further implementation result of the present utility model, in the another kind of embodiment of unstressed trace liftout attachment of the present utility model, on the basis of aforementioned content, the height of above-mentioned push rod be jacking block height 13-17 doubly, the 13-17 that the L1 in figure is L2 doubly, we can any value implement within the scope of this, can reduce further the impact on working stress trace so again.
In order to optimize further implementation result of the present utility model, as shown in Figure 1, in the another kind of embodiment of unstressed trace liftout attachment of the present utility model, above-mentioned mandrel plate 2 comprises upper ejector pin plate 21 and the lower push rod plate 22 setting gradually.
In order to optimize further implementation result of the present utility model, as shown in Figure 3, in the another kind of embodiment of unstressed trace liftout attachment of the present utility model, on the surface that above-mentioned jacking block 6 contacts with workpiece 7, be also matrix and be arranged with a plurality of the second jacking blocks 62, this second jacking block 62 preferably carries out elasticity with jacking block 6 and is connected, so not only can on the basis of jacking block 6, further form the effect of the more excellent trace that eliminates stress, also can reduce the impact of jacking block 6 on workpiece 7 contact-making surfaces.
Introduce the course of work of the present utility model below, shown in Fig. 1-2, during matched moulds, die 4 arrives male model plate 37 times with workpiece, and push rod 5 touches workpiece together with jacking block 6, after workpiece 7 moulding, then carries out parting, and 5 jacking blocks of push rod leave workpiece 7 together.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
