Description

Technical Field

[0001] This utility model relates to a screw hole structure for the assembly and disassembly process of an inclined top, belonging to the field of plastic mold technology. Background Technology

[0002] The angled ejector head of a plastic mold is the main forming part of the angled ejector mechanism, responsible for the internal or external barbs of the molded product and assisting in demolding during the ejection process. However, the existing angled ejector head and ejector pin are an integral structure, which leads to inconvenience in later maintenance. To solve the above problems, a new technical solution is provided. Utility Model Content

[0003] The purpose of this utility model is to provide a screw hole structure for the disassembly and assembly process of an angled top head, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a screw hole structure for disassembling and assembling a slanted top head, comprising a slanted top seat, wherein a fixing screw hole and a rotating shaft are provided on the slanted top seat, the fixing screw hole is symmetrically and equidistantly opened on both sides of the slanted top seat, the rotating shaft is rotatably connected to the middle of the interior of the slanted top seat, a top rod is welded to the outside of the rotating shaft, a docking shaft hole is opened at the top of the top rod, a spring, a first pin hole and a slanted top insert are provided on the docking shaft hole, the spring is nested inside the docking shaft hole, the first pin hole is opened below the docking shaft hole, the slanted top insert is nested inside the docking shaft hole, and the slanted top insert is pressed against the top of the spring.

[0005] Preferably, the inclined top insert is provided with an inclined top head and a second pin hole, the inclined top head is integrally formed and connected to the top of the inclined top insert, and the second pin hole is opened below the inclined top insert.

[0006] Preferably, the second pin hole and the first pin hole are symmetrical in size and position, and the second pin hole is connected to the first pin hole by a pin.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: a push rod is welded to the outside of the rotating shaft, which allows the push rod to swing easily; the inclined push insert is nested in the docking shaft hole, which allows the inclined push head to be connected to the docking shaft hole; the second pin hole is connected to the first pin hole through a pin, which can fix the inclined push head to the docking shaft hole; in summary, this utility model can easily install and remove the inclined push head, effectively improving the mold maintenance efficiency. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the inclined top seat structure of this utility model; Figure 3 This is a schematic diagram of the inclined top structure of this utility model; In the diagram: 1-sloping top seat; 2-fixing screw hole; 3-rotating shaft; 4-top rod; 5-connecting shaft hole; 6-spring; 7-first pin hole; 8-sloping top insert; 9-sloping top head; 10-second pin hole; 11-pin. Detailed Implementation The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0009] like Figure 1-3 As shown, a screw hole structure for assembling and disassembling a slanted top includes a slanted top seat 1. The slanted top seat 1 has fixed screw holes 2 and a rotating shaft 3. The fixed screw holes 2 are symmetrically and equidistantly located on both sides of the slanted top seat 1. The rotating shaft 3 is rotatably connected to the center of the slanted top seat 1. A top rod 4 is welded to the outside of the rotating shaft 3. A mating shaft hole 5 is provided at the top of the top rod 4. A spring 6, a first pin hole 7, and a slanted top insert 8 are provided on the mating shaft hole 5. The spring 6 is nested inside the mating shaft hole 5. The first pin hole 7 is located below the mating shaft hole 5. The slanted top insert 8 is nested inside the mating shaft hole 5 and is pressed against the spring 6. A slanted top 9 and a second pin hole 10 are provided on the slanted top insert 8. The slanted top 9 is integrally formed and connected to the top of the slanted top insert 8. The second pin hole 10 is located below the slanted top insert 8. The second pin hole 10 and the first pin hole 7 are symmetrical in size and position, and the second pin hole 10 is connected to the first pin hole 7 via a pin 11.

[0010] Specific usage: When the inclined pusher 9 needs to be replaced or maintained, remove the pin 11 from the second pin hole 10 and the first pin hole 7. At this time, the inclined pusher insert 8 is pushed out from the mating shaft hole 5 by the spring 6. The inclined pusher 9 can then be easily removed from the push rod 4, which effectively improves the loading and unloading efficiency of the inclined pusher 9.

[0011] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
