DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figures 1 to 5 As shown, a movable grinding disc seat mold of an embodiment of the utility model includes: a lower mold 100, an upper mold 200, and a material ejecting device 400. It should be noted that this embodiment requires a rubber layer 310 to be cast on the outer peripheral side of the movable grinding disc seat 300. The movable grinding disc seat 300 has a vertical center hole 301, and the lower end surface of the movable grinding disc seat 300 has a notch 302.

[0037] The lower mold 100 has a concave cavity, and the upper mold 200 is located on the upper side of the lower mold 100. The upper mold 200 is used to cooperate with the lower mold 100 to form a receiving cavity to accommodate the movable grinding wheel seat 300. In this embodiment, a concave-convex structure is provided on the lower side of the upper mold 200, and the concave-convex structure of the upper mold 200 cooperates with the concave cavity of the lower mold 100 to form an receiving cavity. After the movable grinding wheel seat 300 is placed in the receiving cavity, a molding cavity is formed on the outer peripheral side of the movable grinding wheel seat 300. A pouring channel is provided on the upper mold 200 for injecting pouring material into the molding cavity after the mold is closed, thereby molding a rubber layer 310 on the outer peripheral side of the movable grinding wheel seat 300. The above structure is a conventional structure, so it will not be explained in detail here. It can be understood that in order to position the movable mold plate seat so that the upper mold 200 and the lower mold 100 can form a molding cavity with the movable grinding plate seat 300, a positioning frustum 102 is provided at the center of the concave cavity of the lower mold 100. The positioning frustum 102 is used to extend into the center hole 301 of the movable grinding plate seat 300 to radially position the movable grinding plate seat 300. In addition, a positioning protrusion 103 is also provided at the inner end of the concave cavity of the lower mold 100. The positioning protrusion 103 is used to be embedded in the notch 302 on the lower end surface of the movable grinding plate seat 300 to prevent the movable grinding plate seat 300 from rotating during casting and affecting the casting quality.

[0038] The lifting device 400 is located at the lower side of the lower mold 100, and the lifting device 400 includes a lifting part 410 and a driving part 420. The lifting part 410 can be raised and lowered, and an elastic buffer mechanism 430 is provided at the top of the lifting part 410. The driving part 420 is transmission-connected to the lifting part 410, and the driving part 420 is used to drive the lifting part 410 to rise and fall, wherein a vertically through lifting hole 101 is provided on the lower mold 100, and the lifting part 410 can pass through the lifting hole 101 under the drive of the driving part 420 and lift the movable grinding disc seat 300 upward through the elastic buffer mechanism 430.

[0039] It is obvious that when the upper mold 200 and the lower mold 100 are closed, the molding cavity formed on the peripheral side of the movable grinding disc seat 300 is isolated from the ejection hole 101. In addition, it is conceivable that the driving part 420 can adopt a manual structure or an automatic structure.

[0040] After the casting and molding of the movable grinding disc seat mold of the embodiment of the utility model is completed, the upper mold 200 is first removed, and then the driving part 420 is used to drive the top material part 410 to rise and pass through the top material hole 101 to extend into the lower mold 100, and the movable grinding disc seat 300 is lifted upward by the elastic buffer mechanism 430 at the top of the top material part 410, so that the movable grinding disc seat 300 after casting and molding is separated from the lower mold 100, which makes it convenient to take materials, and in the process of lifting the movable grinding disc seat 300, elastic buffering can be provided by the elastic buffer mechanism 430 to avoid direct rigid contact, so that the rubber layer 310 formed on the peripheral side of the movable grinding disc seat 300 can be slowly separated from the lower mold 100, thereby reducing the damage of the rubber layer 310 and improving the product quality.

[0041] Reference Figure 1 and Figure 2 As shown, it can be understood that the ejection portion 410 is provided with a plurality of vertically extending ejection rods 411, the ejection rods 411 are adapted to and correspond to the ejection holes 101, and the elastic buffer mechanism 430 is provided at the top of the ejection rods 411. By providing a plurality of ejection rods 411, the force on the movable grinding disc seat 300 can be more uniform and the lifting can be smoother. Specifically, in this embodiment, as Figure 4 As shown, the ejection portion 410 is provided with a connecting frame 415, and multiple ejection rods 411 are all arranged on the upper side of the connecting frame 415 to connect the multiple ejection rods 411 into a whole, and the multiple ejection rods 411 are evenly distributed around the central hole 301 of the movable grinding disc seat 300.

[0042] Reference Figure 1 , Figure 4 and Figure 5As shown, it can be understood that the elastic buffer mechanism 430 includes a buffer rod 431 and an elastic member 432. The buffer rod 431 is vertically slidably installed on the top of the ejecting rod 411. The buffer rod 431 is used to abut against the bottom end of the movable grinding disc seat 300. The elastic member 432 is arranged between the buffer rod 431 and the ejecting rod 411. The elastic member 432 is used to apply an upward elastic force to the buffer rod 431. When the movable grinding disc seat 300 is lifted after molding, the driving part 420 drives the ejecting part 410 to rise. During the rising process of the ejecting part 410 The buffer rod 431 first contacts the bottom end of the movable grinding disc seat 300, and then the elastic member 432 is elastically compressed and indirectly applies an upward elastic force to the movable grinding disc seat 300 through the buffer rod 431, and as the compression amount increases, the elastic force gradually increases, thereby slowly lifting the movable buffer seat, and the rubber layer 310 formed on the peripheral side of the movable grinding disc seat 300 can be slowly separated from the lower mold 100, reducing damage to the rubber layer 310. By setting the above structure to provide elastic buffering when lifting the movable grinding disc seat 300, the structure is simple and practical.

[0043] Reference Figure 4 and Figure 5 As shown, it can be understood that the upper end surface of the ejector rod 411 is provided with a vertically extending mounting hole 412, and the buffer rod 431 is partially inserted into the mounting hole 412 to vertically slide with the mounting hole 412, so that the buffer rod 431 is vertically slidably mounted on the ejector rod 411, and the structure is simple and practical; in addition, a limiting structure is provided between the buffer rod 431 and the ejector rod 411, and the limiting structure is used to keep the buffer rod 431 at least partially located in the mounting hole 412, so that the buffer rod 431 has a stable mounting structure to prevent the buffer rod 431 from being separated from the mounting hole 412. Obviously, the limiting structure can be detachably arranged to facilitate the removal and replacement of the buffer rod 431. It can be understood that in order to prevent the elastic member 432 from exceeding its compression limit and being damaged, the bottom end of the mounting hole 412 is set as a blind end, and when the bottom end of the buffer rod 431 abuts against the bottom wall of the mounting hole 412, the condition that the elastic member 432 does not exceed the compression limit should be met.

[0044] Reference Figure 4 and Figure 5As shown, it can be understood that the limiting structure includes a limiting pin 433 horizontally penetrated through the buffer rod 431. Obviously, the limiting pin 433 is detachably penetrated through the buffer rod 431. In addition, the opposite sides of the mounting hole 412 are respectively provided with limiting grooves 413 which are horizontally penetrated and vertically distributed. The upper and lower ends of the limiting groove 413 are both closed ends, and the two ends of the limiting pin 433 are respectively embedded in the two limiting grooves 413. Obviously, the limiting pin 433 can slide vertically along the limiting groove 413, and the vertical sliding stroke of the buffer rod 431 is limited by the cooperation between the limiting pin 433 and the limiting groove 413, so that the buffer rod 431 always remains in a state of being at least partially located in the mounting hole 412. When the buffer rod 431 needs to be removed, the limiting pin 433 is horizontally pushed out from the buffer rod 431, and then the buffer rod 431 can be taken out from the mounting hole 412. The structure is simple and easy to disassemble and assemble.

[0045] Reference Figure 4 and Figure 5 As shown, it can be understood that a boss 434 is provided at the top of the buffer rod 431, and the elastic member 432 is configured as a compression spring and is sleeved on the buffer rod 431, and both ends of the compression spring respectively abut against the lower end surface of the boss 434 and the upper end surface of the ejector rod 411, thereby applying an upward elastic force to the buffer rod 431, and the structure is simple and practical; it can be understood that the upper end surface of the boss 434 is horizontal, and the boss 434 is used to contact the movable grinding disc seat 300 to lift the movable grinding disc seat 300, so the upper end surface of the boss 434 is horizontal to make the movable grinding disc seat 300 more evenly stressed.

[0046] Reference Figures 1 to 3 As shown, it can be understood that the material lifting part 410 is vertically slidably installed on the lower mold 100, and the material lifting part 410 is provided with a vertically distributed rack 414, and the driving part 420 includes a gear 421 meshing with the rack 414, and the gear 421 is coaxially fixed with a rotating shaft 422, and the rotating shaft 422 is rotatably arranged on the lower side of the lower mold 100, and a manual part 423 is provided at one end of the rotating shaft 422, and the manual part 423 is configured to accept operation to drive the rotating shaft 422 to rotate, so that the rotating shaft 422 can be rotated by operating the manual part 423, so as to utilize the cooperation of the gear 421 and the rack 414 to drive the material lifting part 410 to rise, the structure is simple and the cost is low, and the manual operation also has the advantage of sensing the force feedback of the movable grinding disc seat 300, and the lifting speed can be adjusted at any time. In a further embodiment, the manual part 423 is at least partially located outside the projection range of the lower mold 100 in the vertical direction, that is, the manual part 423 at least partially extends from the circumferential edge of the lower mold 100. Such a configuration makes it convenient for operators to operate the manual part 423 without having to extend their hands under the lower mold 100. Specifically, the manual part 423 is configured as a turntable, and a handle is eccentrically disposed on the turntable. The handle is shaken to drive the rotating shaft 422 to rotate, and the structure is simple and practical.

[0047] Reference Figures 1 to 3As shown, in some specific embodiments, the ejection portion 410 is provided with a ejection rod 411, which is vertically slidably matched with the ejection hole 101, and the number of the ejection rods 411 corresponds to the number of the ejection holes 101. The lower side of the lower mold 100 is detachably provided with an abutment frame 110, and the abutment frame 110 is used to abut against the ejection portion 410 to limit the downward stroke of the ejection portion 410 and keep the ejection rod 411 at least partially located in the ejection hole 101, so that the ejection rod 411 is always slidably matched with the ejection hole 101, so that the ejection portion 410 is slidably installed on the lower mold 100, providing a sliding guide for the ejection portion 410 in the vertical direction. Obviously, when the ejection portion 410 needs to be removed, the abutment frame 110 is removed first, so that the ejection rod 411 can be separated from the ejection hole 101.

[0048] Reference Figures 1 to 3 As shown, in a further embodiment, the rotating shaft 422 is rotatably arranged on the abutment frame 110, and at least two mounting seats are provided on the lower side of the abutment frame 110 to rotatably install the rotating shaft 422. With such an arrangement, during disassembly and assembly, the driving part 420 and the abutment frame 110 can be disassembled and assembled as a whole, which makes the operation more convenient and the structure simpler.
