Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model discloses a secondary ejection mechanism of car light card line structure, as shown in fig. 2-7, including movable mould 1, thimble board 2, bottom plate 3, first thimble 4, have the second thimble 5 of card line structure, stop collar 6 and elastic component 7, movable mould 1, thimble board 2 and bottom plate 3 parallel arrangement in order, set up the first through-hole 11 and the second through-hole 12 of guide first thimble 4 and second thimble 5 in the movable mould 1, the one end of first thimble 4 is fixed on thimble board 2, the other end is arranged in first through-hole 11, through the vertical removal of thimble board 2, drive first thimble 4 along the vertical removal of first through-hole 11. One end of the second thimble 5 with the wire clamping structure is arranged in the second through hole 12, and a wire clamping structure is formed by a gap between the second thimble and the upper surface of the movable die 2; the other end of the second ejector pin 5 is fixedly provided with a limiting sleeve 6, the limiting sleeve 6 comprises a first step portion 61 and a second step portion 62, the first step portion 61 is larger than the first through hole 11, namely, the second step portion 61 cannot enter the first through hole 11, the upward moving position of the second ejector pin 5 is limited, a third through hole 21 allowing the first step portion 61 to pass through is formed in the ejector pin plate 2, and the upward moving position of the second step portion 62 is limited through the third through hole 21. The second thimble 5 is fixedly connected with the bottom plate 3 through an elastic piece 7; wherein the elastic member 7 may be a spring.

When a product is ejected, firstly, a movable die and a fixed die need to be opened, as shown in fig. 2, after the product is ejected, an ejector plate 2 is driven to move upwards, so that a first ejector pin 4 moves upwards to eject the product, meanwhile, a second ejector pin 5 is pushed by an elastic piece 7 and is blocked by a third through hole 21, and the second ejector pin 5 moves upwards synchronously along with the first ejector pin 4 until a first step part 61 is blocked by a second through hole 12; at this point, the product has been ejected out of the moving mold and the first stage ejection is complete, as shown in FIG. 6. Then, the ejector plate 2 drives the first ejector pin 4 to move upwards continuously, and the first step part 61 is blocked by the second through hole 12 to limit the second ejector pin 5 to move upwards continuously; at this time, the product has an upward pushing force, the wire clamping structure of the product is elastically deformed and separated from the second ejector pin 5, and the ejection at the second stage is finished, as shown in fig. 7.

In an embodiment, the mold further comprises a supporting rod 8, the supporting rod 8 is used for supporting the second thimble 5, when the mold is closed, the thimble plate 2 moves downwards to make the second thimble 5 contact with the supporting rod 8, the supporting rod 8 limits the second thimble 5 to move downwards continuously, and the second thimble 5 is fixed by matching with the third through hole 21, so that the second thimble 5 is kept stationary during casting. And also as a guide for the elastic element 7, whereas the elastic element 7 is deflected to both sides when compressed.

In an embodiment, two first pins 4 are provided, and are symmetrically provided on two sides of the second pin 5. Therefore, the product can be stably ejected.

In one embodiment, a limiting block 9 is arranged on the ejector plate 2 and used for limiting the upward moving distance of the ejector plate 2 so as to control the ejection distance of a product. By replacing the limiting block 9, the upward moving distance of the ejector plate 2 is adjusted, and the product is knocked to be separated from the second ejector pin 5, so that the production efficiency is improved. In a specific embodiment, the limiting block 9 is fixed through a screw, and the height of the limiting block 9 is adjusted through the screw, so that the moving distance of the ejector plate 2 is adjusted. The limiting plate 9 is prevented from being repeatedly replaced, and the adjusting efficiency is improved.

In one embodiment, the ejector plate 2 is provided with a fourth through hole 22 allowing the second step portion to move, and when the ejector plate 2 moves upward, the elastic member 7 is extended, and a part of the elastic member is located in the fourth through hole 22, which corresponds to the fourth through hole 22 as a guide groove thereof, and guides the elastic member 7 to extend vertically.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
