Abstract
It is a kind of delay core-pulling die, including cover half, dynamic model, fixed block, take-up housing, shovel, sliding block fuse, cover half mold insert the utility model discloses the utility model；The cover half and dynamic model is abutted against together, type chamber is protruded into the inner end of sliding block fuse, the outer end of sliding block fuse is fixed on take-up housing, take-up housing slips in dynamic model, the lower part of shovel is threaded through in the guide groove of take-up housing, and the inner sidewall of shovel lower part and guide groove inner sidewall are against cover half mold insert upper end is fixed on cover half, and the lower end of cover half mold insert penetrates sliding block fuse.Since the guide groove in the shovel and take-up housing of the utility model has one section of straight section cooperation, shovel, which blocks take-up housing delay using its straight body position, does not allow its outward movment to be drawn upwardly out certain stroke, it moves upwards cover half mold insert and is detached from product back-off, extraction sliding block fuse completes slipper block loose core process after shovel continues up, there is back-off in effective solution sliding block fuse bottom, have the advantages that motion stability is reliable.
Description
Technical field
The utility model relates to a kind of injection molds, more particularly to a kind of delay core-pulling die.
Background technique
Plastics injection mould is the tool for producing plastic products, very widely used.In plastic products injection molding, it is
The needs for meeting moulding process should control the sequence of mould core pulling, and the core-pulling mechanism commonly used is unable to satisfy wanting for core pulling control
It asks.
Summary of the invention
The purpose of this utility model is to provide a kind of motion stability reliably to postpone core-pulling die.
To achieve the above object, the technical solution of the utility model is:
The utility model is a kind of delay core-pulling die, including cover half, dynamic model, fixed block, take-up housing, shovel, sliding block core
Son, cover half mold insert；The cover half and dynamic model is abutted against together, and type chamber, the outer end of sliding block fuse are protruded into the inner end of sliding block fuse
It is fixed on take-up housing, take-up housing slips in dynamic model；The take-up housing offers guide groove, which is one oblique
Slot, the upper section of guide groove inner sidewall is skew wall, middle section is straight wall, lower section is skew wall；The shovel is obliquely installed, and the upper end is solid
It is scheduled on cover half, the inner sidewall of shovel lower part is made of skew wall, straight wall and skew wall from top to bottom, and the lower part of shovel is threaded through sliding block
In the guide groove of seat, and the inner sidewall of shovel lower part and guide groove inner sidewall against；The cover half mold insert upper end is fixed on fixed
On mould, the lower end of cover half mold insert penetrates sliding block fuse.
The utility model further includes two slider layerings, which is symmetrically fixed in dynamic model, in two cunnings
The sliding slot for making take-up housing sliding is formed between block press strip.
After adopting the above scheme, since there is the guide groove in the shovel and take-up housing of the utility model one section of straight section to match
Close, shovel using its straight body position block take-up housing delay does not allow its outward movment to be drawn upwardly out certain stroke, make cover half mold insert to
Upper movement is detached from product back-off, completes first time core pulling, and shovel continues up rear entire take-up housing outward movment extraction and slides
Block fuse completes slipper block loose core process, and effective solution sliding block fuse bottom has back-off, can with motion stability
By the advantages of.
The utility model is further described in the following with reference to the drawings and specific embodiments.

Fig. 2 is the top view of the utility model molding；
Fig. 3 is the front view of the utility model die sinking for the first time；
Fig. 4 is the top view of the utility model die sinking for the first time；
Fig. 5 is second of front view being opened of the utility model；

Specific embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of delay core-pulling die, including cover half 1, dynamic model 2, fixed block 3, cunning
7, two block 4, shovel 5, sliding block fuse 6, cover half mold insert slider layerings 8.
The cover half 1 and dynamic model 2 is abutted against together, and two slider layerings 8 are symmetrically fixed in dynamic model 2,
The sliding slot 81 for making take-up housing 4 sliding is formed between two slider layerings 8.
Type chamber is protruded into the inner end of the sliding block fuse 6, and the outer end of sliding block fuse 6 is fixed on take-up housing 4, take-up housing 4
It slips in the sliding slot 81 in dynamic model 2 between two slider layerings 8；The take-up housing 4 offers guide groove 41, the guide groove
42 be a skewed slot, and the upper section 421 of 42 inner sidewall of guide groove is skew wall, middle section 422 is straight wall, lower section 423 is skew wall；Described
Shovel 5 is obliquely installed, and the upper end is fixed on cover half 1, and the inner sidewall of 5 lower part of shovel is from top to bottom by skew wall 51,52 and of straight wall
Skew wall 53 is constituted, and the lower part of shovel 5 is threaded through in the guide groove 41 of take-up housing 4, and the inner sidewall of 5 lower part of shovel and guide groove 41
Inner sidewall against；7 upper end of cover half mold insert is fixed on cover half 1, and the lower end of cover half mold insert 7 penetrates sliding block fuse 6.
Working principle of the utility model is:
As shown in Figure 3, Figure 4, die sinking movement start when, shovel 5 by its straight wall 52 block take-up housing 4 delay do not allow its outward
Movement is drawn upwardly out certain stroke, moves upwards cover half mold insert 7 and is detached from product back-off, completes first time core pulling；
As shown in Figure 5, Figure 6, when being then opened, entire 4 outward movment of the take-up housing extraction cunning after continuing up of shovel 5
Block fuse 6 completes slipper block loose core process.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of being covered with new patent.
