Further, described grafting piece and mounting blocks are structure as a whole.
Further, described first draw stub bar and the first knock-pin to be structure as a whole.
Further, described second draw stub bar and the second knock-pin to be structure as a whole.
Further, described locating dowel is cylinder form.
Adopt the Drawing-Core sprue puller that ejects in straight top of technique scheme, because described mounting blocks is provided with the first knock-pin and the second knock-pin, the first knock-pin is identical with the shape size of the second knock-pin, the end of the first knock-pin is provided with first and draws stub bar, first draws stub bar to be T-shaped shape, the end of the second knock-pin is provided with second and draws stub bar, second draws stub bar to be T-shaped shape, the first knock-pin and the second knock-pin are and are arranged in parallel, the sidewall of mounting blocks is provided with grafting piece, mounting blocks is provided with slot and locating dowel, mounting blocks is provided with groove, the bottom of mounting blocks is provided with tip-angled shape structure, tip-angled shape structure towards face, be externally cambered surface, the bottom surface of mounting blocks is cancave cambered surface, mounting blocks is provided with slot, the root of the first knock-pin and the second knock-pin is plugged on respectively in slot, so adopt this directly to push up the Drawing-Core sprue puller that ejects, can make plastic part stay this side of dynamic model, by the first knock-pin and the second knock-pin, realize fast demoulding, efficiency improves greatly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is that the utility model directly pushes up the Drawing-Core structural representation that ejects sprue puller.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, the Drawing-Core sprue puller that ejects in a kind of straight top, comprise mounting blocks 1, mounting blocks 1 is provided with the first knock-pin 2 and the second knock-pin 4, the first knock-pin 2 is identical with the shape size of the second knock-pin 4, the end of the first knock-pin 2 is provided with first and draws stub bar 3, first draws stub bar 3 to be T-shaped shape, the end of the second knock-pin 4 is provided with second and draws stub bar 5, second draws stub bar 5 to be T-shaped shape, the first knock-pin 2 and the second knock-pin 4 are and are arranged in parallel, the sidewall of mounting blocks 1 is provided with grafting piece 10, mounting blocks 1 is provided with slot 7 and locating dowel 8, mounting blocks 1 is provided with groove 6, the bottom of mounting blocks 1 is provided with tip-angled shape structure 11, tip-angled shape structure 11 towards face, be externally cambered surface, the bottom surface of mounting blocks 1 is cancave cambered surface 12, mounting blocks 1 is provided with slot 9, the root of the first knock-pin 2 and the second knock-pin 4 is plugged on respectively in slot 9, grafting piece 10 is structure as a whole with mounting blocks 1, and first draws stub bar 3 and the first knock-pin 2 to be structure as a whole, and second draws stub bar 5 and the second knock-pin 4 to be structure as a whole, and locating dowel 8 is cylinder form.
