[ detailed description ] embodiments
Referring to fig. 1 and fig. 2, fig. 1 is a schematic view illustrating the core-pulling structure of the present invention in a mold, and fig. 2 is a schematic view illustrating the core-pulling structure of the present invention in a mold clamping state.
In this embodiment, the insert core-pulling structure of the present invention is used for forming a product in a mold, where the mold includes a cavity plate 10, a cavity 11, a core plate 12, a core 13, an upper ejector plate 14, and a lower ejector plate 15, the product 16 has a circular hole 17 in an inner side of the core, a diameter of the circular hole 17 may be greater than 3.5 mm, and the insert core-pulling structure includes:
a jack 100, one end of which is fixed in the upper jack plate 14;
one end of the ejector block 200 is arranged in the male template 12 and connected with the other end of the ejector rod 100, and the other end of the ejector block forms the inner side of the product 16;
the insert 300 is provided with a round hole 17 for forming a product 16 at one end and transversely penetrates through the top block 200 at the other end;
the slide block 400 is arranged in a guide groove 18 formed in the core insert 13, the guide groove 18 is arranged in an inclined manner, the other end of the insert 300 is fixed in the slide block 400, and the slide block 400 slides along the guide groove 18 in an inclined manner to drive the insert 300 to retreat from the circular hole 17.
The number of the ejector rods 100 is two, and after the mold is opened, the two ejector rods 100 can more stably jack up the jacking block 200 and the product 16.
Wherein, the one end that ejector pin 100 and kicking block 200 are connected has T type piece 101, correspondingly be equipped with T type groove on the kicking block 200, T type piece 101 is located in the T type groove to can make ejector pin 100 and kicking block 200 more firmly be connected.
The other end of the insert 300 is fixed in the slider 400 by the round pin 301, so that the other end of the insert 300 is more firmly fixed in the slider 400, and the insert 300 smoothly exits from the round hole 17 when the slider 400 moves along the guide groove 18.
The distance from the top end of the slider 400 to the top end of the guide groove 18 is greater than the stroke of the ejector rod 100, and the stroke of the ejector rod 100 is the distance from the upper ejector plate 14 to the male die plate 12, so that the slider 400 is prevented from being separated from the guide groove 18 during the upward movement of the slider 400 along the guide groove 18 during the ejection process, and in a preferred embodiment, the distance from the top end of the slider 400 to the top end of the guide groove 18 is greater than 8 mm of the stroke of the ejector rod 100.
Referring to fig. 3 and 4, fig. 3 is a schematic view illustrating the core-pulling structure of the insert in an open mold state according to the present invention, and fig. 4 is a partially enlarged view of fig. 3.
After the product 16 is injection molded, the mold is opened, and the male template 12 is separated from the female template 10; then, the upper ejection plate 14 and the lower ejection plate 15 are ejected upwards to drive the ejector rod 100, the ejector block 200 and the product 16 to be ejected upwards; when the top block 200 is ejected upwards, because the insert 300 penetrates through the top block 200 and the other end of the insert 300 is fixed in the slider 400, the top block 200 drives the insert 300 to move upwards, and the slider 400 slides in the guide groove 18 in an inclined manner, so that the insert 300 moves upwards and retreats from the circular hole 17 of the product 16, and the core pulling action is completed.
Compared with the prior art, the insert core-pulling structure has the advantages that the ejector rod 100 and the ejector block 200 are used for ejecting, the insert 300 is used for completing core-pulling during ejection, an inclined pin seat and an inclined pin are not needed for core-pulling, the phenomena that the round hole 17 of the product 16 is deformed by pulling and is whitened are avoided, and the appearance of the round hole 17 is effectively improved.
