Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inclined top injection molds, in particular to a two-stage inclined top injection mold. Background Art
[0002] The mold is usually demoulded by straight ejection. Inclined ejection and internal extraction are usually used when the inner shape of the product has buckles, bosses, or recessed surfaces. External extraction is usually used when the outer side of the product needs to be cored, such as: the outer surface has convex or concave surfaces, or holes. When the external extraction distance is relatively short, an inclined guide column is usually used. When the external extraction distance is relatively long, hydraulic or mechanical methods are usually used for core extraction. As mold components, inclined ejectors, sliders, slides, and stop locks are generally referred to as inclined ejectors below.
[0003] Currently, there is a product with a slider on the outside, but also an undercut on the inside that needs to be demoulded. The conventional method is to use a slanted ejector for demoulding. However, the conventional slanted ejector is not easy to fall off after ejection and is prone to getting the product stuck. To solve this problem, we developed a two-stage slanted ejector injection mold. Utility Model Content
[0004] The purpose of the utility model is to provide a two-stage top inclined top injection mold to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a two-stage top inclined top injection mold, including an inclined top injection mold main body, the inclined top injection mold main body is mainly composed of an upper template, a lower template, a pin plate, a male template, and a female template, and a two-stage top inclined top assembly is built in between the male template and the female template.
[0006] Preferably, the two-stage top inclined top assembly includes two outer sliding blocks, and a product is arranged between the two outer sliding blocks. The shape of the product is a convex square, and the outer side of the upper end of the product is inverted outward, and the inner walls of the lower end of the product are inverted inward on both sides.
[0007] Preferably, two oblique inserts are provided inside the product, the top outer walls of the oblique inserts match the inner walls of the product, and the bottom ends of the oblique inserts are provided with an integral extended pin protrusion.
[0008] Preferably, the two-stage roof inclined roof assembly further includes a pull rod and a guide block slidably arranged on the outer wall of the pull rod.
[0009] Preferably, a recess adapted to fit the integral extended pin protrusion is provided on one side of the top end of the pull rod, and a pull rod screw is provided at the bottom end of the pull rod.
[0010] The utility model provides a two-stage top and inclined top injection mold. It has the following beneficial effects:
[0011] (1) The present invention designs a product in the shape of a convex square, and the outer side of the upper end of the product is inverted outward, and the inner walls of the lower end of the product are inverted inward. This ensures that the outer slider can slide smoothly during the demoulding process, and effectively avoids the problem of product jamming caused by the inverted inner wall, thereby achieving an efficient and stable demoulding process.
[0012] (2) The utility model can effectively realize the ejection and return of the product during the injection molding process by setting up a two-stage inclined ejector assembly, and significantly improve the production efficiency. The design of the inclined insert not only improves the internal precision of the product, but also strengthens the overall structural stability of the mold. In addition, during the molding process of the product, the inclined insert is used for the inner side of the product to be buckled, which can also reduce the deformation rate of the product. The pull rod plays the role of applying tension and thrust to the inclined insert. The design of the guide block aims to accurately position the guide pull rod. This component structure is simple and safe, compact in structure, and occupies little space. It is suitable for products with complex internal structures. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0022] The preferred embodiment of the two-stage top inclined top injection mold provided by the utility model is as follows: Figure 1-6 As shown: A two-stage top inclined ejector mold, including an inclined ejector mold body 1, the inclined ejector mold body 1 is mainly composed of an upper template 11, a lower template 12, an ejector plate 14, a male template 13, and a female template 15. A two-stage top inclined ejector assembly 2 is built between the male template 13 and the female template 15. The two-stage top inclined ejector assembly 2 includes two outer sliders 21, and a product 22 is arranged between the two outer sliders 21. The shape of the product 22 is a convex square, and the outer side of the upper end of the product 22 is an outer inverted buckle 221. The product 2 2 has inverted buckles 222 on both sides of the inner wall at the lower end. Two inclined inserts 23 are installed inside the product 22. The top outer walls of the inclined inserts 23 match the inner walls of the product 22, and the bottom ends of the inclined inserts 23 are provided with integrated extended pin protrusions 231. The two-stage top inclined ejector assembly 2 also includes a pull rod 24 and a guide block 25 slidably arranged on the outer wall of the pull rod 24. A recess 241 is formed on one side of the top end of the pull rod 24 to match the integrated extended pin protrusions 231. A pull rod screw 26 is installed at the bottom end of the pull rod 24. The pull rod screw 26 serves to secure the pull rod 24.
[0023] When in use, the mold achieves efficient molding of the product 22 through the precise cooperation of the two-stage top inclined ejector assembly 2, and during the injection molding process of the product 22, the ingenious design of the two-stage top inclined ejector assembly 2 makes the demolding of the product smoother, improves production efficiency and reduces production costs. When the mold is opened, after the slider moves, the ejector plate begins to eject, driving the pull rod 24, and the pull rod 24 ejects and drives the inclined insert 23. The inclined insert 23 stops after reaching the designed stroke, and the pull rod 24 and the ejector continue to eject, and finally the product falls off.
