Detailed Description
Referring to fig. 1 to 4, the utility model discloses a direct-pushing glue-feeding oblique-pushing auxiliary demoulding mould structure, which comprises a rear mould component, wherein the rear mould component comprises a rear mould base 1 and an ejector plate 2, a rear mould insert 3 is arranged in the rear mould base 1, a straight ejector rod 4 and an oblique ejector rod 5 are arranged on the ejector plate 2, the oblique ejector rod 5 is hinged with the ejector plate 2, a straight ejector block 6 is arranged on the straight ejector rod 4, an ejector block groove is arranged on the rear mould insert 3, a straight guide hole and an oblique guide hole are arranged at the bottom of the ejector block groove, the straight ejector block 6 is positioned in the ejector block groove, the straight ejector rod 4 passes through the straight guide hole and can move up and down along the straight guide hole, the top surface of the straight ejector block 6 and the top surface of the rear mould insert 3 form a forming surface of a product 14 together, an oblique ejector groove is arranged at the bottom surface of the straight ejector block 6, one end of the oblique ejector rod 5 is positioned in the oblique ejector groove, and the oblique ejector rod 5 passes through the oblique guide hole and can move up and down along the oblique guide hole, the top block groove comprises an oblique guide surface 7, a runner groove 8 is arranged on the surface of the straight top block 6, the oblique top rod 5 and the oblique guide surface 7, which are in contact, and the runner groove 8 is sealed by the oblique guide surface 7 so as to form a glue injection runner.
As shown in the figure, the runner groove 8 is positioned at the top end edge of the oblique ejector rod 5, and the structure is that the glue is not easily clamped in the runner groove 8 arranged in the oblique ejector rod 5 after the oblique ejector rod 5 stirs the glue stick out of the runner.
As shown in the figure, the ejecting plate 2 is provided with a connecting seat 9, and the inclined ejector rod 5 is hinged with the connecting seat 9. Be equipped with the spread groove 10 on the connecting seat 9, be equipped with on the both sides wall of this spread groove 10 and connect spout 11, be equipped with in the connection spout 11 and connect slide 12, the lower extreme of oblique ejector pin 5 is equipped with spliced pole 13, this spliced pole 13 with connect the spout normal running fit on the slide 12, when realizing the 2 rectilinear rising movements of knockout plate through above-mentioned structure, oblique ejector pin 5 can follow oblique guide hole and remove and can not block because oblique ejector pin 5 can rotate and remove along connecting spout 11 through spliced pole 13 and through connecting slide 12.
The structure principle is as follows: when demolding, the front mold is separated from the rear mold assembly, then the ejector plate 2 drives the straight ejector rod 4 and the inclined ejector rod 5 to move, so that a product 14 positioned on the rear mold insert 3 is ejected out, the glue can be remained in the U-shaped glue injection runner to form a glue stick, the glue stick can not be ejected out when being clamped in the glue injection runner, the glue injection runner comprises a runner groove 8 and an inclined guide surface 7, therefore, when the straight ejector block 6 rises linearly, the surface of the straight ejector block 6, which is in contact with the inclined guide surface 7, can be separated from the inclined guide surface 7, meanwhile, the inclined ejector rod 5 can move upwards along the inclined guide surface 7, and the inclined ejector rod 5 can be pulled out from the runner groove 8 of the straight ejector block 6, so that the product 14 can be taken out from the rear mold insert 3 at last, and the phenomenon that the product cannot be demolded because the glue stick is clamped in the runner groove 8 can be avoided.
The straight-jacking glue-feeding inclined-jacking auxiliary demolding mold structure provided by the embodiment of the invention is described in detail, and the principle and the implementation mode of the invention are explained by applying a specific example, and the description of the above embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
