Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an inclined guide column protection mechanism. Background Art

[0002] Autonomous driving systems require a variety of sensors, such as lidar, millimeter-wave radar, ultrasonic radar, and cameras. The data from multiple sensors is integrated to enhance the system's perception capabilities and provide autonomous vehicles with safe, stable, and reliable system capabilities.

[0003] LiDAR plays a crucial role in this. The system can use the point cloud information scanned by the LiDAR to identify static and dynamic obstacles and predict their trajectories. Automotive LiDAR is usually installed on the car body using a mounting bracket.

[0004] Furthermore, automotive LiDAR mounting brackets are typically manufactured using injection molding, which involves injecting heated, molten material into a mold cavity under high pressure, where it cools and solidifies to form a finished product.

[0005] In conventional injection molds, after the movable and fixed molds are separated, the slider must be slid out before the workpiece can be removed from the molding cavity. To reclose the movable and fixed molds, the slider must first be reset. Conventional methods typically use manual methods to separate and reset the slider. To improve work efficiency, some employ inclined guide pins to drive the slider out during the mold opening and closing strokes.

[0006] However, in the prior art, there is a situation where the reset of the inclined guide pin drives the slider to reset. At this time, during the mold closing stroke, the inclined guide pin will be broken, which has certain shortcomings. Utility Model Content

[0007] The purpose of the present utility model is to provide an inclined guide column protection mechanism to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inclined guide column protection mechanism, comprising a fixed mold and a movable mold, a forming table is provided between the movable mold and the fixed mold, and a slider is slidably connected to the forming table; a linkage component for driving the slider to slide is provided between the movable mold and the fixed mold; the linkage component comprises an inclined guide column mounted on the movable mold, an inclined guide groove adapted to the inclined guide column is provided on the slider, and a flaring component is provided between the inclined guide column and the inclined guide groove.

[0009] Furthermore, the flaring component includes a flaring groove provided on the oblique guide groove, an arc groove is provided on the bottom of the oblique guide column, and the flaring groove is adapted to the arc groove.

[0010] Furthermore, a limit member is provided between the slider and the mold to improve the stability of the slider when sliding on the mold.

[0011] Furthermore, the limiting component includes a limiting block installed on the mold, a convex strip is fixedly connected to the slider, a limiting groove is provided on the limiting block, and the convex strip is slidably connected in the limiting groove.

[0012] Furthermore, an insert for molding a workpiece is installed on the slider.

[0013] Furthermore, a connecting piece is provided between the inclined guide column and the movable mold to improve the stability of the inclined guide column during installation.

[0014] Furthermore, the connecting piece includes a protrusion fixedly connected to the inclined guide column, and a slot adapted to the protrusion is provided on the movable mold, and the protrusion is engaged with the slot.

[0015] Furthermore, it also includes a base, and the movable mold is installed on the base.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the inclined guide pin protection mechanism, through the cooperation between the fixed mold, the movable mold, the linkage, the slider and the flaring component, allows the inclined guide pin to slide inside the inclined guide groove during the mold opening stroke, thereby driving the slider to slide outward. When preparing to close the mold, when the inclined guide pin is inserted into the inclined guide groove, it will first pass through the flaring component, thereby greatly improving the accuracy of the inclined guide pin's insertion into the inclined guide groove. Then, during the mold closing stroke, the inclined guide pin will be inserted into the inclined guide groove here, and the slider is driven by the inclined guide pin to slide into the mold. Therefore, the risk of the inclined guide pin breaking can be avoided, the practicality of the protection mechanism is improved, and the working needs are met. BRIEF DESCRIPTION OF THE DRAWINGS
