DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0030] Refer to Figure 1 Figure 3 An embodiment provided by the utility model: ​

[0031] A bearing cap production mold for easy demolding includes a base 1. Four symmetrically arranged support legs are fixedly connected to the bottom surface of the base 1. The interior of the base 1 has a groove structure to accommodate the turntable 41 in the unfolding assembly 4. The four support legs provide stable support for the base 1, ensuring its stability during operation. A cover plate 2 is fixedly connected to the surface of the base 1. The surface of the cover plate 2 has four arrayed through slots 21. The cover plate 2 is installed on the surface of the base 1 to reduce dust ingress and provides a flat surface for placing the mold plate 3. The through slots 21 provide a sliding path for the movable seat 44, ensuring that the movable seat 44 can move along a preset trajectory. Four sets of mold plates 3 are arranged in an array on the surface of the cover plate 2. The four sets of mold plates 3 are spliced ​​together to form the mold body, which provides the required cavity for the forming of the bearing cap. During the production process, the liquid bearing cap material is injected into this cavity. After cooling, it forms the required bearing cap shape and can be spliced ​​and separated under the action of the unfolding component 4, avoiding the friction between the cavity and the side wall of the bearing cap, and realizing the rapid demolding of the bearing cap.

[0032] Reference Figure 2 - Figure 3 The base 1 has an internal unfolding assembly 4, which includes a turntable 41 rotatably connected to the base 1. The surface of the turntable 41 has four symmetrically arranged inclined grooves 42. An extrusion rod 43 is slidably connected inside the inclined grooves 42. A movable seat 44 is fixedly connected to the end of the extrusion rod 43 and slidably connected inside the through groove 21. When the turntable 41 rotates, the inclined grooves 42 provide a specific trajectory for the extrusion rod 43, allowing it to move linearly along the direction of the inclined grooves 42, thereby driving the movable seat 44 and the mold plate 3 to move. The movable seat 44 is fixedly connected to the bottom surface of the mold plate 3. The surface of the turntable 41 has a through hole, and a rotating shaft 45 is fixedly connected to the through hole. The rotating shaft 45 passes through and is rotatably connected to the bottom surface of the base 1. A motor 46 is fixedly connected to the bottom surface of the base 1, and the output shaft of the motor 46 is fixedly connected to the bottom end of the rotating shaft 45. The motor 46 drives the turntable 41 to rotate via the rotating shaft 45. The inclined groove 42 on the surface of the turntable 41 cooperates with the extrusion rod 43 to convert the rotational motion of the turntable 41 into the linear motion of the extrusion rod 43, thereby realizing the unfolding and splicing of the mold plate 3.

[0033] Reference Figure 2 - Figure 3, four groups of mold plates 3 between the setting of ejection assembly 5, ejection assembly 5 includes sleeve 51, sleeve 51 through and slidingly connected in the bottom surface of the cover plate 2, sleeve 51 and the outer wall of the shaft 45 is threadedly connected, the top end of the sleeve 51 is fixedly connected with the top plate 52, the top plate 52 is between the four groups of mold plates 3, when the motor 46 drives the rotating disc 41 to rotate through the shaft 45, the sleeve 51 drives the top plate 52 to press the formed bearing cover from the cavity formed by the mold plate 3 under the action of the shaft 45, and the demolding process is completed.

[0034] Referring to Figure 3 - Figure 4 , the mold plate 3 and the top plate 52 are provided with a guide assembly 6, the guide assembly 6 includes a sliding groove 61, the sliding groove 61 is opened on the surface of the mold plate 3, the sliding groove 61 is slidably connected with a sliding block 62, the surface of the sliding block 62 is fixedly connected with a telescopic rod 63, the top end of the telescopic rod 63 is fixedly connected with the bottom surface of the top plate 52, the sliding groove 61 provides a specific path for the sliding of the sliding block 62, ensures that the sliding block 62 can move along the predetermined direction, and the separation and splicing of the four groups of mold plates 3 are not affected by the guide assembly 6. The top plate 52 is connected with the sliding block 62 through the telescopic rod 63, so that the top plate 52 cannot rotate with the rotation of the shaft 45 during the ejection process, so that the top plate 52 stably rises or falls under the action of the rotation of the shaft 45. The inside of the sliding groove 61 is fixedly connected with a guide rod 64, the guide rod 64 penetrates and is slidably connected on the side wall of the sliding block 62, the guide rod 64 provides further guiding action for the sliding of the sliding block 62, and at the same time limits the movement range of the sliding block 62, preventing it from deviating from the track of the sliding groove 61 during sliding.

[0035] Working principle: when the bearing cover needs to be produced, the motor 46 is started, and the motor 46 drives the rotating disc 41 to rotate through the shaft 45. The inclined groove 42 on the surface of the rotating disc 41 cooperates with the extrusion rod 43 to convert the rotary motion of the rotating disc 41 into the linear motion of the extrusion rod 43. The extrusion rod 43 drives the moving seat 44 and the mold plate 3 fixedly connected therewith to move during the linear motion, realizes the splicing of the mold plate 3, and thus forms a complete cavity. The liquid bearing cover material is injected into the cavity formed by the splicing of the four groups of mold plates 3.

[0036] After the bearing cover material is cooled and formed, the motor 46 is started again, and the motor 46 reversely rotates the rotating disc 41 through the shaft 45. The inclined groove 42 on the surface of the rotating disc 41 cooperates with the extrusion rod 43 again to drive the mold plate 3 to move in the opposite direction, realizing the unfolding of the mold plate 3. At this time, the formed bearing cover is left between the mold plates 3.

[0037] Meanwhile, when the motor 46 drives the rotating disc 41 to rotate through the rotating shaft 45, the sleeve 51 is connected with the outer wall of the rotating shaft 45 through threads, and the sleeve 51 is lifted or lowered along the axial direction of the rotating shaft 45 under the rotation of the rotating shaft 45. The lifting or lowering of the sleeve 51 drives the top plate 52 fixedly connected with the sleeve 51 to be lifted or lowered. When the top plate 52 is lifted, it pushes out the formed bearing cover from the cavity formed by the mold plate 3, and the demolding process is completed.

[0038] During the lifting or lowering of the top plate 52, the telescopic rod 63 and the guide assembly 6 play a role in stabilizing and guiding. The telescopic rod 63 connects the top plate 52 with the sliding block 62, so that the top plate 52 cannot rotate with the rotating shaft 45 during the ejection process. The sliding groove 61, the sliding block 62 and the guide rod 64 in the guide assembly 6 ensure that the sliding block 62 can move along the preset direction, limit the movement range of the sliding block 62, and prevent the sliding block 62 from deviating from the track of the sliding groove 61 during the sliding process.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
