Description

Technical Field

[0001] The utility model relates to the technical field of mold tilting ejectors, in particular to a tilting ejector mechanism for a mold. Background Art

[0002] The mold tilting top, also known as the tilting tip or tilting top, is a mechanism used in mold design to form the internal hook of the product. It is suitable for relatively simple hook situations.

[0003] According to the Chinese patent publication number: CN 218906205U, a tilting ejector mechanism for precision molds is disclosed. By setting a rotating shaft, a bearing, a slider and a slide seat, the tilting ejector rod and the tilting ejector head can move more flexibly, which can prevent the tilting ejector rod from breaking due to jamming and improve the safety of the tilting ejector mechanism. The setting of the connecting pin enables the tilting ejector head to be easily disassembled and replaced, which can reduce the maintenance cost of the tilting ejector mechanism when the tilting ejector head is damaged. In this technical solution, the tilting ejector head is connected and fixed by the connecting pin and the tilting ejector rod, and the connecting pin and the tilting ejector head and the tilting ejector rod are connected by extrusion and friction. As a result, when the tilting ejector head is in use, the connecting pin may be separated from the tilting ejector head and the tilting ejector rod due to vibration, thereby affecting the stability of the tilting ejector head. For this reason, we propose a tilting ejector mechanism for molds. Utility Model Content

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-8 As shown, the utility model provides a technical solution: a tilting ejector mechanism for a mold, comprising a tilting ejector head 1, a tilting ejector rod 2, a slider 3 and a slide 4, a disassembly mechanism 5 is provided between the tilting ejector head 1 and the top of the tilting ejector rod 2, the slider 3 is hinged to the bottom end of the tilting ejector rod 2, and the slider 3 is slidably connected to the inner wall of the slide 4;

[0028] The disassembly and assembly mechanism 5 includes a mounting block 501 and a U-shaped frame 504. The mounting block 501 is fixedly mounted on the bottom end of the inclined ejector head 1. A mounting groove 502 is provided at the top of the inclined ejector rod 2. The mounting block 501 is inserted into the mounting groove 502. The U-shaped frame 504 is sleeved on the front of the inclined ejector rod 2, and the U-shaped frame 504 is slidably connected to the outer wall of the inclined ejector rod 2. A clamping strip 505 is fixedly mounted on the inner wall of the U-shaped frame 504. Clamping slots 503 are provided on both sides of the mounting block 501. The clamping strip 505 movably passes through the front of the inclined ejector rod 2 and is clamped in the clamping slot 503.

[0029] Specifically, the above technical solution is that when the inclined ejector head 1 needs to be disassembled and replaced, the mold inclined ejector mechanism can pull the U-shaped frame 504 outward through the pull ring 6, and the U-shaped frame 504 drives the limit slider 3 to compress the spring 506, and the U-shaped frame 504 drives the clamping bar 505 to move outward, so that the clamping bar 505 disengages from the clamping slot 503, so that the clamping bar 505 no longer limits the mounting block 501, and then the inclined ejector head 1 can be pulled upward to disengage the mounting block 501 from the mounting slot 502, thereby completing the disassembly of the inclined ejector head 1, and then the new inclined ejector head 1 can be installed on the inclined ejector rod 2, so that the mounting block 501 on the new inclined ejector head 1 is inserted into the mounting slot 502, and then the pull ring 6 is released. At this time, the limit slider 3 will drive the U-shaped frame 504 to the inclined ejector head under the reset force of the spring 506. When the rod 2 moves in the direction of rotation, the U-shaped frame 504 drives the clamping strip 505 to be inserted into the installation groove 502, so that the clamping strip 505 is clamped in the clamping slot 503, and the installation block 501 is limited and fixed, thereby completing the installation of the new inclined ejector head 1. Through the above structure, it is convenient for personnel to disassemble, assemble and replace the inclined ejector head 1, thereby improving the work efficiency of personnel, and the inclined ejector head 1 is more stable during installation, ensuring the normal use of the inclined ejector head 1, and solving the problem that the inclined ejector head 1 in the existing technical solution is connected and fixed between the connecting pin and the inclined ejector rod 2, and the connecting pin and the inclined ejector head 1 and the inclined ejector rod 2 are connected by extrusion and friction, resulting in the connecting pin of the inclined ejector head 1 being separated from between the inclined ejector head 1 and the inclined ejector rod 2 due to vibration when the inclined ejector head 1 is in use, thereby affecting the stability of the use of the inclined ejector head 1.

[0033] Among them, by providing a limiting rod 509, the limiting slider 508 and the spring 506 can be limited to ensure the stability of the limiting slider 508 when sliding and the spring 506 when being compressed.

[0034] Furthermore, a pull ring 6 is fixedly mounted on the front of the U-shaped frame 504;

[0035] The pull ring 6 is provided to facilitate personnel to pull the U-shaped frame 504 through the pull ring 6 , thereby facilitating operation.
