SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's above defect, and provide an injection molding is ejecting structure to peel off the injection molding when ejecting with the injection molding, let the injection molding drawing of patterns more smoothly, improve production efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme: an ejection structure of an injection molding part comprises an ejector rod and an inclined top capable of moving up and down, wherein the moving direction of the inclined top is an up-down inclined line direction forming an acute angle with a vertical line, the upper part of the inclined top is used for being reversely buckled in the injection molding part when injection molding is completed, the upper part of the inclined top is a part forming a mold core, the outer side surface of the upper part of the inclined top forms a part of the outer surface of the mold core, and the outer side surface of the upper part of the inclined top is attached to the inner wall of the injection molding part; the upper end of the ejector rod is attached to the lower edge of the injection molding piece in the horizontal direction; when the injection molding machine is used for demolding, the inclined top moves upwards, the top surface of the upper part of the inclined top pushes the injection molding piece to be upwards separated from the mold core gradually, and the ejector rod is used for preventing the injection molding piece from moving in the horizontal direction along with the inclined top.
The direction vector of the upward movement of the oblique top is decomposed into a vertical direction vector and a horizontal direction vector, and the horizontal direction vector points to the middle direction of the injection molding piece.
One or more ejection structures are arranged on the corresponding mold core.
Two ejector rods are arranged on two sides of the inclined top respectively.
The upper end of the ejector rod is attached to one surface of the lower edge of the injection molding piece facing to the middle direction of the injection molding piece in the horizontal direction.
Compared with the prior art, the utility model beneficial effect be: the ejector rod is arranged to stop the horizontal movement of the injection molding part, and the oblique ejector pushes up the injection molding part to produce displacement relative to the injection molding part horizontally when the injection molding part is pushed up obliquely, so that the injection molding part can be smoothly stripped from the oblique ejector when the injection molding part is demoulded, the production efficiency is improved, the probability of demoulding problems is reduced, and the quality stability is improved.

It should be noted that, the products shown in the above views are all appropriately reduced/enlarged according to the size of the drawing and the clear view, and the size of the products shown in the views is not limited.
Detailed Description
In order to more fully understand the technical content of the present invention, the technical solution of the present invention will be further described and explained with reference to the specific embodiments.
The embodiment of the utility model provides an ejecting structure of injection molding, its concrete structure is as shown in fig. 1, 2.
As shown in fig. 1 and 2, the ejection structure of the injection molded part 10 includes a top rod 31 and a lifter 20 that can move up and down. The two ejector rods 31 are respectively arranged at two sides of the inclined top 20. The moving direction of the lifter 20 is a vertical inclined line direction forming an acute angle with the vertical line. The direction vector of the upward movement of the lifter 20 is decomposed into a vertical direction vector and a horizontal direction vector, and the horizontal direction vector is directed toward the middle of the injection molded part 10.
The upper portion of the lifter 20 is designed to snap back into the injection molded part 10 when injection molding is complete. The upper portion 21 of the lifter 20 is a part of the mold core (not shown), the outer side surface of the upper portion 21 of the lifter 20 is a part of the outer surface of the mold core, and the outer side surface of the upper portion 21 of the lifter 20 is attached to the inner wall of the injection molded part 10. The upper end of the ejector pin 31 engages the lower edge 11 of the injection molded part 10 in the horizontal direction. The upper end of the ejector rod 31 is horizontally attached to the surface of the lower edge 11 of the injection molded part 10 facing the middle of the injection molded part 10. During demolding, the lifter 20 moves upwards, the top surface of the upper part 21 of the lifter 20 pushes the injection molding part 10 to be separated from the mold core gradually, the ejector rod 31 can push against the injection molding part 10 to prevent the injection molding part 10 from moving along with the lifter 20 in the horizontal direction, and therefore the injection molding part 10 can generate a gap with the lifter 20 to be separated.
In this embodiment, one or more ejection structures are disposed on a corresponding mold core. In other embodiments, more than 1 ejection structure is disposed on a corresponding mold core.
This embodiment stops injection molding 10 horizontal migration through setting up ejector pin 31, and 20 oblique tops produce the displacement to the relative injection molding 10 level of 20 oblique tops when upwards jacking injection molding 10 to one side, just can let injection molding 10 peel off with 20 oblique tops smoothly simultaneously when the injection molding 10 drawing of patterns, improved production efficiency, reduce the probability of drawing of patterns out of the patterns problem, improve the stability of quality.
The above description is only for the purpose of illustrating the technical content of the present invention by way of example, so as to facilitate the understanding of the reader, but does not represent that the embodiments of the present invention are limited thereto, and any technical extension or re-creation according to the present invention is protected by the present invention.
