Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically a T-slot inclined top side core-pulling mold mechanism. Background Technology
[0002] For products with irregularly shaped surfaces, such as car bumpers, during the demolding process of injection molding, the ejector plate is driven to move and together with the ejector pins on it to lift the injection-molded product out, thus completing the demolding. However, due to the presence of protrusions and depressions in the product and the internal structure of the mold, direct demolding may cause interference between the structures. Therefore, it is necessary to set up an additional side core-pulling mechanism and a corresponding side drive device. This makes the mold structure complex, costly, and inconvenient for early assembly and later maintenance. Utility Model Content

[0006] The inclined ejector block is embedded in the first positioning groove and can slide tilted on the bottom surface of the first positioning groove. The mold core is smoothly connected to the outer surface of the inclined ejector block and matches the surface of the product.
[0007] The ejector pin is perpendicular to the bottom surface of the first positioning groove and passes through the mold core. The slider at the top of the ejector pin is laterally slidably docked with the guide seat at the bottom of the inclined ejector block.
[0008] As a further description of the above technical solution:
[0009] One side of the first positioning groove is inclined and a plurality of first guide blocks are provided thereon, and the guide groove on the wedge-shaped surface of one side of the inclined top block is slidably connected with the first guide block.
[0010] As a further description of the above technical solution:

The boss on the side of the second guide block is joined with the boss on the side of the first guide block to perform lateral positioning.
[0012] As a further description of the above technical solution:
[0013] The slider and the guide seat slide together in a T-shaped structure.
[0014] As a further description of the above technical solution:
[0015] The bottom surface of the first positioning groove extends downward to form a second positioning groove, and the guide seat is embedded in the second positioning groove.
[0016] As a further description of the above technical solution:

[0018] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0019] In use, the inclined ejector side core-pulling mold mechanism of this invention drives the ejector plate inside the mold to move, pushing the ejector pins on it upwards.

[0028] Please see Figure 1-3 This utility model provides a technical solution: a T-slot inclined top side core-pulling mold mechanism, comprising:
[0029] Mold core 1, on which a first positioning groove 2 is provided;
[0030] The inclined ejector block 3 is embedded in the first positioning groove 2 and can slide on the bottom surface of the first positioning groove 2. The mold core 1 is smoothly connected to the outer surface of the inclined ejector block 3 and matches the surface of the product 100.
[0031] The ejector pin 5 is perpendicular to the bottom surface of the first positioning groove 2 and passes through the mold core 1. The slider 6 at the top of the ejector pin 5 is laterally slidably connected to the guide seat 4 at the bottom of the inclined ejector block 3.
[0032] In this design, one side of the first positioning groove 2 is inclined and has several first guide blocks 7. The guide groove 8 on the wedge-shaped surface of one side of the inclined top block 3 slides and engages with the first guide blocks 7. The side of the guide groove 8 extends into a positioning groove 9. The guide groove 8 and the positioning groove 9 form a stepped structure. A second guide block 10 is provided in the positioning groove 9. The boss on the side of the second guide block 10 is engaged with the boss on the side of the first guide block 7 to perform lateral positioning.
[0033] The slider 6 and the guide seat 4 slide and connect with the groove 11, and both are T-shaped structures.
[0034] A second positioning groove 12 extends downward from the bottom surface of the first positioning groove 2, and the guide seat 4 is embedded in the second positioning groove 12. A third guide block 13 is provided on one side of the first positioning groove 2, and the notch 14 on the side of the inclined top block 3 is fitted with the third guide block 13. This improves the stability of the sliding between the inclined top block 3 and the first positioning groove 2 and the ejector pin 5.
[0035] The working principle of the T-slot inclined ejector side core-pulling mold mechanism in this embodiment includes: during use, the ejector plate inside the mold is driven to move, and the ejector pins 5 on it are pushed upward together. The inclined ejector block 3 is pushed upward and tilted by the guidance of the first positioning groove 2. During this period, the inclined ejector block 3 and the slider 6 perform adaptive lateral sliding to realize the ejection of the product 100 and synchronous side core pulling, avoiding structural interference and improving the demolding, injection molding quality and efficiency. Thus, the vertical lifting drive output of the inclined ejector block 3 can be converted into the tilting movement of the inclined ejector block 3 through the above structure, thereby reducing the use of drive equipment and simplifying the mold structure.
