Description

Technical Field

[0001] This utility model relates to the field of die casting molds, specifically a side core pulling mechanism. Background Technology

[0002] In die casting molds, the side core pulling mechanism is the core component for forming transverse holes (i.e., the axis of the hole is perpendicular to the mold opening direction) in the casting. However, if the temperature difference between the mold core and the side core is large during the die casting process, weld lines and other defects may appear on the surface of the casting, which will affect the quality of the casting. Utility Model Content

[0003] The purpose of this invention is to address the above problems by providing a side core-pulling mechanism that can adjust the temperature of the side core.

[0004] To achieve the above objectives, the technical solution adopted in this application is: a side core-pulling mechanism, including a sleeve plate, a mold core installed in the middle of the sleeve plate, a side core provided on the mold core, the core-pulling direction of the side core being perpendicular to the mold opening direction, the side core being hollow, and an inlet and outlet communicating with the interior being spaced apart along its axial direction on the outer wall of the side core, and an inner tube in the same direction being provided inside the side core, the outer wall of the inner tube being sealed to the inner wall of the side core through a sealing part, the inner tube being hollow and open at both ends, the open ends of the inner tube serving as a connecting inlet and a connecting outlet respectively, the inlet and outlet being located on both sides of the sealing part respectively. During the die casting process, the regulating liquid enters the side core from the inlet and flows out from the outlet to reduce the temperature difference between the side core and the mold core, thereby facilitating the adjustment of die casting parameters, reducing defects such as weld lines, and improving the quality of the casting; during die casting, the front end of the side core extends into the mold cavity, and after die casting, it exits the mold cavity, thereby completing the formation of the transverse hole.

[0005] Furthermore, the side core passes through the mold core and connects to the side slider. The side slider moves within the guide groove provided on the sleeve plate. The outer diameter of the side slider matches the inner diameter of the guide groove, and the two are keyway fits, thereby providing precise guidance for the side core.

[0006] Furthermore, in order to enable automatic core pulling of the side core, a support frame is provided on the side end of the sleeve plate, and a side core pulling drive mechanism for driving the side slider to move is provided on the support frame.

[0007] Furthermore, the side core is connected to the base at the far end of the mold core, and the base is detachably connected to the side slider to facilitate the processing of the side core and subsequent maintenance.

[0008] The beneficial effects of this application are as follows: The regulating liquid enters the side core from the inlet and flows out from the outlet, thereby reducing the temperature difference between the side core and the mold core, which facilitates the adjustment of die casting parameters, reduces defects such as weld lines, and improves the quality of castings; through the inner tube, the regulating liquid is prevented from flowing directly into the side core from the inlet and out from the outlet, but is forced to enter the side core from the end of the side core away from the mold core, and then flow to the front end of the side core (extending into the mold core area) and then turn back, thereby increasing the heat exchange area and improving the heat exchange efficiency; during die casting, the front end of the side core extends into the cavity, and after die casting, it exits the cavity, thereby completing the formation of the transverse hole.

[0016] 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.

[0017] Example 1, as Figures 1-5As shown, the specific structure of this embodiment is a side core-pulling mechanism, including a sleeve plate 301. A mold core 302 is installed in the middle of the sleeve plate. A side core 306 is provided on the mold core 302. The core-pulling direction of the side core 306 is perpendicular to the mold opening direction. In this embodiment, the front end refers to the end closer to the mold core, and the rear end refers to the end farther from the mold core. The side core 306 is a sealed columnar structure. The side core 306 is hollow inside. The outer wall of the side core 306 is provided with an inlet 313 and an outlet 314 that communicate with its interior along its axial direction. During the die casting process, when the side core 306 is fully inserted into the mold cavity, the inlet 313 and the outlet 314 are both located outside the mold core 302, that is, the inlet 313 and the outlet 314 are far away from the mold core. The liquid inlet 313 and liquid outlet 314 are respectively connected to the liquid inlet and liquid outlet of the mold temperature control mechanism via connecting pipes. The mold temperature control mechanism can be an oil temperature controller, a water temperature controller, etc. The side core 306 passes through the mold core 302 and is connected to the side slider 310. The side slider 310 moves within the guide groove provided on the sleeve plate 301. The guide groove can be a T-slot. A support frame 311 is provided on the side end of the sleeve plate 301. The support frame 311 is provided with a side core pulling drive mechanism 312 for driving the side slider 310 to move. The side core pulling drive mechanism 312 can be a hydraulic cylinder, etc. The side core 306 is connected to the base 323 at the far end of the mold core 302. The base 323 and the side slider 310 are detachably connected by bolts, etc.

[0018] The side core 306 is provided with an inner tube 315 in the same direction. The outer wall of the inner tube 315 is sealed to the inner wall of the side core 306 through a sealing part 316. The inner tube 315 is hollow and open at both ends. The open ends of the inner tube 315 serve as a connecting inlet and a connecting outlet, respectively. The liquid inlet 313 and the liquid outlet 314 are located on both sides of the sealing part 316. The sealing part divides the interior of the side core 306 into two independent spaces along its axial direction.

[0019] Before molding, the side slider 310 moves horizontally towards the mold core 302, pushing the front end of the side core 306 into the cavity of the mold core 302. After molding, the side slider 310 retracts horizontally, pulling the side core out of the cavity, thus creating a transverse hole in the casting 1. During molding, the liquid output from the mold temperature control mechanism enters the side core 306 through the inlet 313, enters the inner tube 315 through the connecting inlet, and then flows into the space between the inner tube 315 and the side core 306 from the connecting outlet, finally flowing out from the outlet 314. In this working state, the connecting inlet is located at the rear end of the inner tube 315. Alternatively, the liquid can enter the space between the inner tube 315 and the side core 306 through the inlet 313, then enter the inner tube 315 through the connecting inlet, then flow into the side core 306 from the connecting outlet, and finally flow out from the outlet 314. In this working state, the connecting inlet is located at the front end of the inner tube 315.
