Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
example (b): referring to fig. 1 to 5, a front mold side back-off demolding separating mechanism includes a front mold plate 1, a front mold core 2 and a front mold elastic block 3, wherein a side surface of the front mold plate 1 is provided with the front mold core 2, the other side surface of the front mold plate 1 is provided with the front mold elastic block 3, at least one insert 4 for molding back-off is fixed on the front mold elastic block 3, the other end of the insert 4 penetrates through the front mold plate 1 and the front mold core 2 to form a back-off end, a stroke gap H is formed between the front mold core 2 and the front mold elastic block 3, and the front mold core 2 is separated from a product (plastic part a) before demolding and then is linked with the insert 4 to separate the product back-off. The front mould elastic block is connected with inserts 4, one end of each insert is connected with the front mould elastic block 3, and the other end of each insert extends into the cavity of the front mould core 2. The outer side of the front template 1 is provided with a panel 5, and the front template drives the front mold core to realize the demolding operation. Four corners of the front template 1 are provided with guide posts 6, the guide posts are matched with the rear template 7, the rear template 7 is provided with a rear mold core to be matched with the front mold core, four sliding blocks 81, 82, 83 and 84 are respectively arranged around the space between the front mold core and the rear mold core, the shapes of the sliding blocks are designed according to actual requirements, the sliding blocks are matched with the front mold core, the rear mold core and the mold insert to form a product cavity, ejector pins are matched with the rear template 7 and the rear mold core, and the ejector pins extend to the cavity to eject the product.
As shown in fig. 3, the front mold includes four sets of front mold inserts, also referred to as inserts, each insert type being contained within a product undercut, the four sets of inserts being secured to the front mold spring block. As shown in fig. 4, during mold splitting, the stroke of the front mold elastic block is H, which is designed according to actual requirements, and the stroke of the front mold elastic block in this embodiment is 8 mm.
As shown in fig. 3, in the mold closing state of an embodiment of the present invention, after the front mold plate and the rear mold plate, i.e., the AB plate, are opened for 8mm, the front mold core is separated from the product, and the 4 sets of front mold inserts are further included in the product back-off position, at this time, because the front mold core is separated, the back-off of the product can have a deformed space, the AB plate continues to be opened, and the inserts are forcibly separated from the product back-off; the front mold is completely separated from the product, 4 groups of mechanical sliding blocks are correspondingly separated from the product after the AB plate is opened, and finally, the ejector pins jack up the product as shown in figure 5 and take out the product.
The above description is only an embodiment utilizing the technical content of the present disclosure, and any modification and variation made by those skilled in the art can be covered by the claims of the present disclosure, and not limited to the embodiments disclosed.
