Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold manufacturing technology, specifically to a mold inclined top anti-jamming structure. Background Technology
[0002] Mold making refers to the processing of forming and blanking tools, and also includes die casting molds and plastic molds. Typically, a mold consists of two parts: a male mold and a female mold. The raw material is placed into the mold (in an injection molding machine or die casting machine) and shaped under pressure. When the mold opens, a workpiece determined by the shape of the mold is obtained.
[0003] After mold processing is completed, the finished product needs to be ejected using ejector pins. For products such as automotive parts, due to protruding structures such as angled clips on their sides, conventional vertical ejector pins are insufficient for ejection and degumming. Therefore, inclined ejector pins are required to eject the product in the opposite direction. However, the base of existing inclined ejector pins is fixed and cannot be moved. When the inclined ejector pin is ejected upwards, it encounters resistance in the direction of the inclined movement. This resistance is significant at higher ejection speeds and angles, easily leading to ejector pin breakage during continuous production. This necessitates production stoppage, mold disassembly, and replacement, resulting in longer production cycles and higher production costs. Utility Model Content
[0004] The purpose of this utility model is to provide a mold inclined top anti-jamming structure to solve the above problems.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0007] A square iron is provided on one side of the inclined push rod, and the inclined push rod drives the inclined push sliding seat to slide synchronously on the square iron through the inclined push fixed seat.
[0008] As a further description of the above technical solution, the top of the inclined ejector rod penetrates the mold core, and a lifting block is provided on the top of the inclined ejector rod.
[0009] As a further description of the above technical solution, the middle part of the inclined top rod penetrates the male template, and a guide block is installed inside the male template.

[0011] As a further description of the above technical solution, the inclined top fixing seat is provided with a fixing hole, which is used to install a fixing pin.
[0012] As a further description of the above technical solution, the inclined sliding seat is provided with a fixing groove, the fixing groove is provided with a mounting hole, and the mounting hole is used to install fixing screws.
[0013] As a further description of the above technical solution, the inclined sliding seat is provided with a sliding groove, and the square iron is provided with a sliding protrusion.

[0017] The beneficial effects of this utility model are as follows:
[0018] In this invention, the sliding groove of the inclined ejector sliding seat and the sliding protrusion of the square iron are slidably connected. The bottom of the inclined ejector rod slides obliquely on the square iron synchronously through the inclined ejector fixing seat and the inclined ejector sliding seat, so that the inclined ejector rod can be regarded as moving vertically up and down without being affected by the oblique angle thrust.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0029] like Figures 1-6 As shown, in one embodiment, a mold slant ejector anti-jamming structure includes: a slant ejector rod 1, the bottom of which is mounted on a slant ejector fixing seat 2, and the slant ejector rod 1 is detachably connected to the slant ejector fixing seat 2 and the slant ejector sliding seat 3, to ensure that the slant ejector rod 1 can maintain a stable position and precise movement trajectory during mold operation.
[0030] Furthermore, a square iron 4 is provided on one side of the inclined jacking rod 1, which serves to support and elevate the rod, providing sufficient space for the ejection mechanism and other components to move. The inclined jacking rod 1 can drive the inclined jacking sliding seat 3 to slide synchronously on the square iron 4 through the inclined jacking fixed seat 2, ensuring that the inclined jacking sliding seat 3 can move precisely along the predetermined inclined path during operation. This ensures that the inclined jacking rod 1 can be evenly stressed during the lifting process, reducing wear and improving the stability of movement.
[0031] Specifically, a return pin panel 9 and a return pin base plate 10 are provided between the square iron 4. The return pin panel 9, the return pin base plate 10 and the square iron 4 are installed on the base 11. Return pin rods 12 are symmetrically installed on the return pin panel 9. The return pin panel 9 can provide fixation and support for the return pin rods 12, and the return pin rods 12 play a guiding and positioning role to ensure that the movement between various parts of the mold is coordinated and consistent during the opening and closing process, avoid problems such as jamming and interference, and ensure the normal operation of the mold.
[0032] Please continue reading Figures 1-6 In this embodiment, the top of the inclined ejector rod 1 penetrates the mold core 5, and the top of the inclined ejector rod 1 is also provided with a lifting block 6. After the product is formed, the lifting block 6 can fit with the outer contour of the inclined buckle part of the product, so that the inclined ejector rod 1 can drive the lifting block 6 to lift the product obliquely to achieve degumming.
[0033] Furthermore, the middle part of the inclined top rod 1 penetrates the male template 7, and a guide block 8 is installed inside the male template 7, so that the inclined top rod 1 can be lifted obliquely along a preset angle.
[0034] Furthermore, the bottom of the inclined push rod 1 is provided with a snap-fit groove 101, which allows the fixing pin to be securely snapped into it, thereby achieving a tight connection between the inclined push rod 1 and the inclined push fixing seat 2, enhancing the stability of the connection and facilitating subsequent disassembly and replacement. Correspondingly, the inclined push fixing seat 2 is provided with a fixing hole 201 at its corresponding position. The size and position of the hole correspond to the snap-fit groove 101 at the bottom of the inclined push rod 1. By inserting the fixing pin into the fixing hole 201, the inclined push rod 1 and the inclined push fixing seat 2 can be detachably connected, ensuring that the inclined push rod 1 will not loosen or shift during operation. Correspondingly, the inclined push sliding seat 3 is provided with a fixing groove 301, and the fixing groove 301 is provided with a mounting hole 302 for installing fixing screws, so that the inclined push fixing seat 2 and the inclined push sliding seat 3 can be detachably connected.
[0035] Please continue reading Figures 1-6 In this embodiment, the inclined top sliding seat 3 is provided with a sliding groove 303, and the square iron 4 is provided with a corresponding sliding protrusion 401. The sliding groove 303 of the inclined top sliding seat 3 and the sliding protrusion 401 of the square iron 4 are slidably connected, so that the bottom of the inclined top rod 1 slides synchronously along the preset trajectory on the square iron 4 through the inclined top fixing seat 2 and the inclined top sliding seat 3, thereby ensuring the accuracy and safety of the lifting operation.
[0036] Through the above technical solution, the sliding groove 303 of the inclined top sliding seat 3 and the sliding protrusion 401 of the square iron 4 are slidably connected. The bottom of the inclined top rod 1 slides obliquely on the square iron 4 synchronously through the inclined top fixing seat 2 and the inclined top sliding seat 3, so that the inclined top rod 1 can be regarded as moving vertically up and down, and will not be affected by the oblique angle thrust. This effectively reduces the risk of the inclined top rod 1 breaking, effectively extends the service life of the mold, and reduces the maintenance frequency and maintenance cost.
