Description

Technical Field

[0001] This utility model relates to the field of bottom core-pulling structure technology, and in particular to a conversion core-pulling mechanism for die-casting molds. Background Technology

[0002] Conventional bottom core-pulling structures are usually located at the bottom of the die-casting mold, and both the core-pulling mechanism and the core-pulling cylinder are in a vertical position. This structure greatly increases the overall length of the die-casting mold, thus increasing the overall volume of the mold. In order to reduce the mold volume, the bottom core-pulling mechanism needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a conversion core pulling device for die casting molds, which has the characteristics of ensuring normal operation of core pulling and reducing the overall volume of the mold.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A conversion core-pulling mechanism for die-casting molds is provided, including a lower mold structure and a bottom core-pulling mechanism. A bottom core-pulling mechanism is installed on one side of the lower part of the lower mold structure. The core-pulling end of the bottom core-pulling mechanism is inserted laterally into the lower part of the lower mold structure. The bottom core-pulling mechanism includes a core-pulling cylinder, a slider, and a slider seat. The core-pulling cylinder is installed laterally on the right side of the lower mold structure. A slider seat is embedded in the lower end face of the lower mold structure. A transverse sliding groove is provided on the slider seat. A slider is installed in the transverse sliding groove. A sliding extension with the left end inclined downwards is provided on the upper left end of the slider. Limiting protrusions are provided on the front and rear sides of the upper edge of the sliding extension. A core-pulling seat is slidably installed on the limiting protrusions. A core-pulling structure is installed on the core-pulling seat. A T-shaped oblique sliding groove is provided on the core-pulling seat. The main shaft of the core-pulling cylinder is connected to the slider.

[0005] In this technical solution, a slider seat is installed to enable the slider to slide horizontally along the transverse groove. By designing a sliding extension and a limiting protrusion on the left side of the slider, the slider can be combined with the inclined groove. When the slider moves to the right, it can drive the core-pulling seat to move downwards step by step, thereby enabling the core-pulling seat to drive the core-pulling structure to achieve the core-pulling action.

[0006] As a supplement to this technical solution, a snap-fit ​​groove is provided on the left side of the core-pulling seat and above the left end of the inclined slide groove, and a limiting platform matching the snap-fit ​​groove is provided on the left end of the limiting protrusion. In this technical solution, by setting the snap-fit ​​groove and the limiting platform, the core-pulling seat can be positioned when it slides to the leftmost end of the slider, thus preventing the core-pulling seat from slipping off the slider.

[0007] As a supplement to this technical solution, a cylinder fixing block is installed side by side on the left end of the core-pulling cylinder. The cylinder fixing block is connected to the lower mold structure. The installation of the cylinder fixing block facilitates the installation of the core-pulling cylinder.

[0008] As a supplement to this technical solution, a docking node is provided on the right side of the slider, and a horizontally arranged sliding rod is installed at the docking node. The sliding rod and the main shaft of the core-pulling cylinder are connected by a coupling. The installation of the sliding rod is used to facilitate docking with the main shaft of the core-pulling cylinder.

[0009] As a supplement to this technical solution, sliding rod pads are symmetrically installed on the front and back of the upper end of the slider. The sliding rod pads are provided with a support surface on the side near the slide groove. By designing the sliding rod pads, the sliding rods are prevented from being suspended in the air, thus ensuring the service life of the sliding rods.

[0010] Beneficial effects: This utility model relates to a conversion core-pulling mechanism for die-casting molds. By installing a slider seat, the slider can slide horizontally along a transverse groove. By designing a sliding extension and a limiting protrusion on the left side of the slider, the slider can be combined with the inclined groove. When the slider moves to the right, it can drive the core-pulling seat to move downwards step by step, thereby enabling the core-pulling seat to drive the core-pulling structure to achieve the core-pulling action. It has the characteristics of ensuring normal operation of core-pulling and reducing the overall volume of the mold. Attached Figure Description

[0019] The embodiments of this utility model relate to a conversion core-pulling mechanism for die-casting molds, such as... Figure 1 — Figure 6 As shown, the device includes a lower mold structure 1 and a bottom core puller 2. The bottom core puller 2 is installed on one side of the lower part of the lower mold structure 1. The core puller end of the bottom core puller 2 is inserted horizontally into the lower part of the lower mold structure 1. The bottom core puller 2 includes a core puller cylinder 3, a slider 8, and a slider seat 7. The core puller cylinder 3 is installed horizontally on the right side of the lower mold structure 1. The slider seat 7 is embedded in the lower end face of the lower mold structure 1. The slider seat 7 is provided with a horizontal sliding groove 18. The slider 8 is installed in the horizontal sliding groove 18. The upper left end of the slider 8 is provided with a sliding extension 11 with the left end tilted downward. The front and rear sides of the upper edge of the sliding extension 11 are provided with limiting protrusions 12. The core puller seat 9 is slidably installed on the limiting protrusions 12. The core puller seat 9 is equipped with a core puller structure 10. The core puller seat 9 is provided with a T-shaped oblique sliding groove 13. The main shaft of the core puller cylinder 3 is connected to the slider 8.

[0020] In this technical solution, the slider seat 7 is installed to enable the slider 8 to slide horizontally along the transverse slide groove 18. By designing a sliding extension edge 11 and a limiting protrusion 12 on the left side of the slider 8, the slider 8 can be combined with the inclined slide groove 13. When the slider 8 moves to the right, it can drive the core-pulling seat 9 to move downwards step by step, thereby enabling the core-pulling seat 9 to drive the core-pulling structure 10 to achieve the core-pulling action.

[0021] As a supplement to this technical solution, a snap-fit ​​groove 16 is provided on the left side of the core-pulling seat 9 and above the left end of the inclined slide groove 13. A limiting platform 17 matching the snap-fit ​​groove 16 is provided on the left end of the limiting protrusion 12. In this technical solution, by setting the snap-fit ​​groove 16 and the limiting platform 17, the core-pulling seat 9 can be positioned when it slides to the leftmost end of the slider 8, thus preventing the core-pulling seat 9 from slipping off the slider 8.

[0022] As a supplement to this technical solution, a cylinder fixing block 4 is installed side by side on the left end of the core-pulling cylinder 3. The cylinder fixing block 4 is connected to the lower mold structure 1. The installation of the cylinder fixing block 4 facilitates the installation of the core-pulling cylinder 3.

[0023] As a supplement to this technical solution, a docking node 14 is provided on the right side of the slider 8, and a horizontally arranged sliding rod 6 is installed at the docking node 14. The sliding rod 6 and the main shaft of the core-pulling cylinder 3 are connected by a coupling 5. The installation of the sliding rod 6 is used to facilitate docking with the main shaft of the core-pulling cylinder 3.

[0024] As a supplement to this technical solution, sliding rod pads 15 are symmetrically installed on the front and back of the upper end of the slider 8. The sliding rod pads 15 are provided with a support surface on the side near the slide groove 18. By designing the sliding rod pads 15, the sliding rod 6 is prevented from being suspended in the air, thus ensuring the service life of the sliding rod 6.

[0025] Example

[0026] When the mold is closed, the upper mold structure and the lower mold structure 1 close together to form the mold cavity structure. At this time, the main shaft of the core-pulling cylinder 3 is extended. The main shaft of the core-pulling cylinder 3 pushes the slider 8, which moves to the left. Through the matching formed between the inclined slide groove 13, the sliding extension 11 and the limiting protrusion 12, the core-pulling seat 9 rises until the leftmost end of the slider 8 and the lower mold structure 1 are engaged. Then the core-pulling seat 9 and the core-pulling structure 10 are at their highest positions, indicating that the core-pulling structure 10 is inserted into the mold cavity structure. Then, the aluminum liquid is injected into the mold cavity structure to complete the product molding. After completion, the product is cooled and the mold is opened to remove the part. After the upper core is pulled, the core-pulling cylinder 3 is activated. The main shaft of the core-pulling cylinder 3 retracts, which drives the slider 8 to move to the right. The core-pulling structure 10 moves down gradually along the sliding extension 11, realizing the separation of the core-pulling structure 10 from the product.
