DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 A ceramic mold in this embodiment includes a workbench 1, support seats 2 are fixed to the left and right ends of the lower surface of the workbench 1, a load-bearing frame 3 is fixed to the upper surface of the workbench 1, a demoulding mechanism 4 for quick demoulding is provided in the middle of the upper surface of the workbench 1, and a film pressing mechanism 5 for fixing the film is provided on the upper surface of the load-bearing frame 3.

[0032] In this embodiment, there are four support seats 2 which are evenly distributed on the lower surface of the workbench 1 , providing stable support for the workbench 1 .

[0033] See also Figure 2-3 In order to demould efficiently, the demoulding mechanism 4 in this embodiment includes a base plate 41, two support plates 42, four shaft rods 43 and a first driving member 44. The two support plates 42 are arranged on the left and right sides of the base plate 41 and are convenient for quick demoulding. The four shaft rods 43 are evenly distributed on the front and back sides of the left and right ends of the base plate 41 and are used to limit the support plates 42. The first driving member 44 is arranged in the inner cavity of the workbench 1 and is used to adjust the angle of the support plates 42.

[0034] In this embodiment, the first driving member 44 includes a double-axis motor 441, two first threaded rods 442, two threaded sleeves 443, four hinged seats 444 and two hinged rods 445. The double-axis motor 441 is fixed to the middle of the inner bottom wall of the workbench 1, and the two output shafts of the double-axis motor 441 are respectively fixed to the two first threaded rods 442. The first threaded rods 442 and the threaded sleeves 443 are threadedly connected. The four hinged seats 444 are respectively fixed to the upper surfaces of the two threaded sleeves 443 and the opposite side of the two support plates 42. The left and right sides of the double-axis motor 441 are fixed to the left and right sides of the two support plates 42. The output shafts on the right side rotate, thereby rotating the first threaded rod 442. The rotation of the two first threaded rods 442 causes the threaded sleeves 443 threadedly connected on their surfaces to move in opposite directions. The two ends of the hinged rod 445 are fixedly connected to the opposite sides of the hinged seats 444 on the upper and lower sides. The movement of the threaded sleeves 443 causes the hinged seat 444 on the lower side to move, thereby driving the hinged rod 445 to move, so that the support plate 42 can be driven to rotate toward the side close to the load-bearing frame 3 through the hinged seat 444 on the upper side, and then it can be separated from the injection molded rubber material, which is convenient for the staff to take it, thereby making the demoulding efficiency higher and the defective rate lower.

[0035] Among them, the support plate 42 is rotationally connected with the shaft rod 43, and the first threaded rod 442 is rotationally connected to the inner wall of the workbench 1 through a bearing. A slider is fixed to the lower surface of the threaded sleeve 443, and a straight-line sliding bar is fixed to the left and right ends of the inner bottom wall of the workbench 1. The slider makes horizontal linear motion in the inner cavity of the sliding bar, and the movement of the threaded sleeve 443 drives the slider to slide in the inner cavity of the sliding bar, thereby limiting the movement of the threaded sleeve 443.

[0036] See also Figure 4 In order to quickly press the injection molding rubber material, the pressing mechanism 5 in this embodiment includes a fixed box 51, a second driving member 52 and two load-bearing plates 53. The fixed box 51 is arranged on the upper surface of the load-bearing frame 3 and is used to protect the second driving member 52. The second driving member 52 is arranged in the inner cavity of the fixed box 51 and is used to press the ceramic film. The two load-bearing plates 53 are symmetrically arranged on the left and right side walls of the inner cavity of the load-bearing frame 3 and are used to bear the weight of the second driving member 52.

[0037] The second driving member 52 includes a driving motor 521, a second threaded rod 522, a movable plate 523 and a die body 524. The upper surface of the driving motor 521 is fixed to the left end of the inner top wall of the fixed box 51, the lower surface of the second threaded rod 522 is fixed to the upper surface of the load-bearing plate 53, the upper surface of the second threaded rod 522 passes through the load-bearing frame 3 and extends to the inner cavity of the fixed box 51, and the upper surface of the left second threaded rod 522 is fixed to the output shaft of the driving motor 521. The injection molding rubber can be directly Pour it into the accommodating cavity formed by the base plate 41 and the two support plates 42, and then start the driving motor 521. The output shaft of the driving motor 521 rotates, the second threaded rod 522 is threadedly connected with the movable plate 523, and the die body 524 is fixed in the middle of the lower surface of the movable plate 523. The movement of the movable plate 523 drives the die body 524 to move downward until the die body 524 enters the accommodating cavity. The movable plate 523 fits with the upper surface of the base plate 41 and the two support plates 42 to perform film pressing.

[0038] In this embodiment, the left and right second threaded rods 522 are connected by a belt drive, which drives the left second threaded rod 522 to rotate, and then the right second threaded rod 522 can be rotated through the belt drive. The rotation of the two second threaded rods 522 causes the movable plate 523 threadedly connected on its surface to move downward. The diameter of the die body 524 is smaller than the distance between the left and right support plates 42. Limit rods are fixed on the left and right sides of the movable plate 523. Limit strips in the shape of a straight line are fixed on the opposite sides of the left and right side walls of the inner cavity of the load-bearing frame 3. The limit rods make linear up and down motion in the inner cavity of the limit strip. When the movable plate 523 moves, the limit rods fixed on its left and right sides move downward in the inner cavity of the limit strip, thereby limiting the movement of the movable plate 523.

[0039] The working principle of the above embodiment is:

[0040] (1) The injection molding rubber material can be directly poured into the accommodating cavity formed by the bottom plate 41 and the two support plates 42, and then the driving motor 521 is started. The output shaft of the driving motor 521 rotates, thereby driving the second threaded rod 522 on the left to rotate. Then, the second threaded rod 522 on the right can be rotated through the transmission of the belt. The rotation of the two second threaded rods 522 causes the movable plate 523 threadedly connected to the surface thereof to move downward. At this time, when the movable plate 523 moves, the limit rods fixed on the left and right sides thereof move downward in the inner cavity of the limit strip, thereby limiting the movement of the movable plate 523. The movement of the movable plate 523 drives the die body 524 to move downward until the die body 524 enters the accommodating cavity. The movable plate 523 fits with the upper surfaces of the bottom plate 41 and the two support plates 42 to perform the lamination.

[0041] (2) When the injection molding rubber is to be demoulded, the dual-axis motor 441 can be started, and the output shafts on the left and right sides of the dual-axis motor 441 rotate, thereby rotating the first threaded rod 442. The rotation of the two first threaded rods 442 causes the threaded sleeves 443 threadedly connected to the surfaces thereof to move in opposite directions. The movement of the threaded sleeves 443 drives the slider to slide in the inner cavity of the slide bar, thereby limiting the movement of the threaded sleeves 443. The movement of the threaded sleeves 443 causes the lower hinge seat 444 to move, thereby driving the hinge rod 445 to move, so that the support plate 42 can be driven to rotate toward the side close to the load-bearing frame 3 through the upper hinge seat 444, thereby being separated from the injection molding rubber, making it easier for the staff to take it.
