AI Technical Summary
Existing technologies require secondary processing when producing products with oblique holes in die casting processes, resulting in low production efficiency.
Design a slanted extraction mechanism that, through the cooperation of a sliding seat and a slanted guide groove, enables the slanted hole and the product to be formed synchronously in a single mold closing process. The linear motion of the sliding seat is converted into slanted motion, directly forming the slanted hole and avoiding secondary processing.
It enables one-step forming of inclined holes, improves production efficiency, and eliminates secondary processing steps such as drilling.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of die casting molds, specifically a slanted extraction mechanism. Background Technology
[0002] When producing products with oblique holes using die casting, the oblique hole refers to a hole whose axial direction is neither parallel to nor perpendicular to the mold opening direction. In order to avoid secondary processing and improve production efficiency, the oblique hole and the product need to be formed together in one mold closing process. Utility Model Content
[0003] The purpose of this invention is to address the above problems by providing a slanted extraction mechanism that can simultaneously form slanted holes and products during a single mold closing process, thereby eliminating secondary processing and improving production efficiency.
[0004] To achieve the above objectives, the technical solution adopted in this application is: a slanted core-pulling mechanism, including a fixed mold plate, a support portion provided on the outer wall of the fixed mold plate, a core-pulling drive mechanism provided on the support portion, a piston rod of the core-pulling drive mechanism connected to a laterally movable sliding seat, an inclined guide groove provided on the support portion, the lateral displacement of the sliding seat driving the fixed mold slider to move obliquely along the inclined guide groove, a fixed mold core provided on the side of the fixed mold plate on the fixed mold slider, the fixed mold core being arranged along the direction of the guide groove. The sliding seat moves outwards from the mold, driving the fixed mold core to simultaneously pull outwards obliquely, thereby directly forming an inclined hole on the fixed mold side.
[0005] Furthermore, the sliding seat is provided with a shovel base, and the fixed mold slider is provided with a through hole that mates with the shovel base. During molding, the shovel base is used to lock the fixed mold slider to prevent it from dislodging. After molding, the shovel base pulls the fixed mold core away from the product.
[0006] Furthermore, the end of the shovel base extends obliquely toward the fixed mold plate to ensure that the shovel base can achieve the design effect.
[0007] Furthermore, the support portion is provided with a transverse guide groove that cooperates with the sliding seat, and the transverse guide groove ensures that the moving direction of the sliding seat is strictly consistent with the stroke of the core pulling drive mechanism.
[0008] Furthermore, to facilitate processing, mold fitting, and subsequent maintenance, the fixed mold core is set on the insert base, and the insert base is detachably connected to the fixed mold slider.
[0009] The beneficial effects of this application are: the linear motion of the sliding seat is transformed into an oblique motion that makes the fixed mold core perform the oblique hole forming and demolding requirements, so as to form an oblique hole in one step on the fixed mold side whose axis direction is neither parallel to nor perpendicular to the mold opening direction, eliminating the need for secondary processing such as drilling, thereby improving production efficiency.

[0015] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.
[0016] Example 1, such as Figures 1-4 As shown, the specific structure of this embodiment is a slanted pulling mechanism, including a fixed mold plate 1, and a support part 2 fixed to the outer wall of the fixed mold plate 1 by bolts, etc. The support part 2 is U-shaped, with the opening side facing the fixed mold plate 1. The support part 2 is provided with a core pulling drive mechanism 3, which can be a hydraulic cylinder, etc. The piston rod of the core pulling drive mechanism 3 moves perpendicular to the mold opening direction. The piston rod of the core pulling drive mechanism 3 is connected to a sliding seat 4, so that the moving direction of the sliding seat 4 is perpendicular to the mold opening direction. The inner wall of the support part 2 is provided with a horizontal guide groove 9 that cooperates with the sliding seat, and the horizontal guide groove 9 is perpendicular to the mold opening direction. The sliding seat 4 is provided with a shovel base 8, the end of which extends obliquely towards the fixed mold plate 1. The fixed mold slider 6 is provided with a through hole that cooperates with the shovel base 8. The inner wall of the support part 2 is provided with an inclined guide groove 5, which is consistent with the direction of the inclined hole on the product.
[0017] The lateral displacement of the sliding seat 4 causes the fixed mold slider 6 to move obliquely along the inclined guide groove 5. The fixed mold slider 6 is provided with a fixed mold core 7 on the side of the fixed mold sleeve plate 1. The fixed mold core 7 is arranged along the direction of the inclined guide groove 5.
[0018] The fixed mold core 7 is disposed on the insert base 10, and the insert base is detachably connected to the fixed mold slider 6 by bolts or the like.
[0019] During molding, the sliding seat 4 moves horizontally towards the fixed mold side, pushing the fixed mold core 7 through the fixed mold core and into the cavity, where it closes with the moving mold core to form a sealed cavity.
[0020] After molding, the sliding seat 4 moves horizontally backward, and the fixed mold core 7 is pulled out from the product inclined hole along the preset angle under the trajectory constraint of the inclined guide groove 5 and the action of the shovel base 8, thus obtaining the preset inclined hole on the product.
