[0002] For die-cast products with simpler structures, there are no side recesses or side holes on the products. Generally, they can be formed by a simple flat die-casting mold and then ejected from the dynamic model core block by an ejector pin. For die-cast products with more complex structures, there are side recesses or side holes on the product surface. Generally, an oblique core-pulling mechanism is required to form the side recesses or side holes on the product to ensure that the die-casting mold is opened later and the product adhered to the dynamic model core block is ejected by the oblique core-pulling mechanism.

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0026] like Figures 1 to 4 As shown, an oblique core-pulling mechanism with guided movement includes: a movable mold component 1, an oblique core-pulling rod 101, a pusher component 2 and a first rolling unit 3.
[0027] In the die-casting mold, the movable mold component 1 can move relative to the fixed mold component (not shown in the figure) so that the mold can be opened or closed. The movable mold component 1 has a movable model core block 100. The inclined core pulling rod 101 on the movable model core block 100 cooperates with the movable model core block 100 to form more complex side concave parts of the product. The pusher component 2 is provided with a first rolling unit 3. The end of the inclined core pulling rod 101 away from the movable model core block 100 is arranged on the pusher component 2 and is connected to the first rolling unit 3. The mold is closed and die-cast to form a product. When the mold is opened, the movable mold component 1 is away from the fixed mold component. When the product needs to be demolded from the movable model core block 100, the pushing component 2 connected to the external driving device can be moved closer to the movable mold component 1. At this time, the die-cast product adheres to the movable model core block 100. When the pushing component 2 drives the inclined core-pulling rod 101 to move relative to the movable mold component 1, the inclined core-pulling rod 101 is driven by the pushing component 2 and moves on the movable model core block 100 guided by the movable model core block 100. At the same time, the inclined core-pulling rod 101 slides on the first rolling unit 3, and the inclined core-pulling rod 101 ejects the product, achieving the effect of inclined core-pulling. The mechanism has good stability, simple structure, and is more convenient to use.
[0028] Specifically, Figure 1 , Figure 2 as well as Figure 4 As shown, a limit end block 102 is detachably provided on the end of the inclined core-pulling rod 101 away from the dynamic model core block 100 , and the limit end block 102 is connected to the first rolling unit 3 .
[0029] Since the end portion of the oblique core-pulling rod 101 connected to the dynamic model core block 100 is relatively large in size, while the rod portion of the oblique core-pulling rod 101 is relatively small, the oblique core-pulling rod 101 is inserted into the dynamic model core block 100 and connected to the limiting end portion via bolts, and then the limiting end block 102 is disposed on the pushing assembly 2 and connected to the first rolling unit 3, so that the pushing assembly 2 drives the oblique core-pulling rod 101 to push the product on the dynamic model core block 100 while the limiting end block 102 slides on the first rolling unit 3.
[0030] Furthermore, if Figure 2 and Figure 4 As shown, a base plate 200 and a fixed plate 201 are provided on the pusher assembly 2, the first rolling unit 3 has a first rolling part 300, the first rolling part 300 is provided on the base plate 200, the base plate 200 and the fixed plate 201 are connected by bolts to form a limiting groove 202, the limiting end block 102 is located in the limiting groove 202 and the bottom of the limiting end block 102 is connected to the first rolling part 300.
[0031] The bottom plate 200 is connected to the pusher assembly 2 connected to an external driving device, and the limiting end block 102 is located between the bottom plate 200 and the fixed plate 201. The bottom plate 200 and the fixed plate 201 are connected by bolts to form a limiting groove 202. The limiting groove 202 limits the movement of the limiting end block 102, so that the bottom of the limiting end block 102 is in contact with the first rolling part 300.
[0032] Furthermore, if Figure 3 and Figure 4 As shown, the limiting end block 102 has limiting parts 105 on both sides, the fixing plate 201 is mounted with a cover plate 203 , and the first rolling unit 3 has a second rolling part 301 , which is arranged on the cover plate 203 and is slidably connected to the limiting part 105 .
[0033] The bottom plate 200 and the fixed plate 201 are connected by bolts to form a limiting groove 202, and a cover plate 203 is installed on the fixed plate 201, so that the limiting end block 102 cannot be separated from the limiting groove 202. The limiting end block 102 has limiting parts 105 on both sides, and a second rolling part 301 is installed on the end of the cover plate 203 away from the dynamic model core block 100. The second rolling part 301 is slidably connected to the limiting part 105 to ensure that the limiting end block 102 (and the oblique core pulling rod 101) is more stably and smoothly limited in the limiting groove 202.
[0034] Furthermore, if Figure 4 As shown, rolling elements are provided on the first rolling portion 300 and the second rolling portion 301 , and the rolling elements are in contact with the limiting end block 102 .
[0035] In this embodiment, the rolling member is configured as a roller, and a plurality of rollers are arranged in the horizontal direction. The bottom surface of the limit end block 102 and the limit parts 105 on both sides of the limit end block 102 are in contact with the rollers, so that the oblique core pulling rod 101 will contact the rollers while making an oblique pulling action relative to the dynamic model core block 100. The rollers are caused to roll through the moving contact between the limit end block 102 and the rollers, so that the limit end block 102 moves on the limit groove 202, thereby realizing the core pulling action of the oblique core pulling rod 101.
[0036] It is worth mentioning that the rolling element can also be set as a roller or other component that can drive the limiting end block 102 to move on the limiting groove 202.
[0037] Specifically, Figure 2 and Figure 3 As shown, a guide portion 103 is formed between the two ends of the moving model core block 100 , and a guide hole 104 is provided on the moving model core block 100 , and the guide portion 103 is movably inserted in the guide hole 104 .
[0038] A guide hole 104 is obliquely provided on the dynamic model core block 100, and the guide portion 103 is inserted into the guide hole 104, so that the guide hole 104 serves as a guide for the oblique core pulling rod 101, so that the oblique core pulling rod 101 is used to eject the product adhered to the dynamic model core block 100.
[0039] Furthermore, if Figure 3 As shown, the movable mold assembly 1 is provided with a second rolling unit 4 , which is provided on the movable mold core block 100 and is slidably connected with the guide portion 103 .
[0040] In this embodiment, a second rolling unit 4 is provided on the movable mold assembly 1. The second rolling unit 4 has a third rolling portion 400 and a fourth rolling portion 401. The third rolling portion 400 and the fourth rolling portion 401 are also provided with rolling members that are the same as the first tube member and the second tube member. The third rolling portion 400 and the fourth rolling portion 401 are respectively connected to the two sides of the guide portion 103, so that the oblique core pulling rod 101 can be more stably guided and moved on the movable mold assembly 1 and the movable mold core block 100.
