Description

Technical Field

[0001] The present application relates to the technical field of denture manufacturing, and in particular to a clamping device for denture production. Background Art

[0002] When manufacturing full dentures, it is necessary to embed and fix the full denture wax model in the mold box and then perform the box-ironing process. The mold box is a container for placing the full denture during the box-ironing process. When the box is ironed, the upper cover and the lower box body of the mold box need to be pressed tightly. Part of the side wall of the mold box is an arc surface, and the other part is a flat surface.

[0003] The mold box pressing device in the related art includes a placement plate, a force source and a pressure plate. A bracket is fixedly connected to the placement plate in the vertical direction. A force source is installed on the top of the bracket. The force source is a jack. The output end of the force source faces the placement plate and can move in the vertical direction. The output end of the force source is connected to a pressure plate parallel to the placement plate. When in use, the production staff stacks multiple mold boxes on the placement plate below the pressure plate in the vertical direction, and then controls the force source so that the output end of the force source drives the pressure plate to move downward in the vertical direction to press against the mold box, and applies pressure to the mold box, thereby pressing multiple mold boxes at the same time.

[0004] When stacking manually, the edges of multiple mold boxes need to be aligned in sequence. If the stacked mold boxes are misaligned, the mold boxes are easily deformed when squeezed, making it difficult to open the compressed mold boxes. However, the outer shell of the mold box is irregular, making it difficult for production personnel to align adjacent mold boxes, thus affecting the compression efficiency of the mold boxes. Utility Model Content

[0005] In order to align multiple mold boxes at the same time and improve the pressing efficiency of the mold boxes, the present application provides a pressing device for denture production.

[0006] The present application provides a clamping device for denture production, which adopts the following technical solution:

[0008] Stacking table;

[0009] A first positioning plate, which is arranged in a vertical direction and is fixedly connected to the stacking table;

[0010] The second positioning plate is arranged along the vertical direction and is slidably connected to the stacking table. The sliding direction is close to or away from the first positioning plate. A clamping area is formed between the first positioning plate and the second positioning plate. The stacking table inside the clamping area is used for stacking the mold boxes.

[0011] By adopting the above technical solution, the production staff stacks multiple mold boxes on the stacking table in the pressing area in the vertical direction, and then pushes the second positioning plate towards the first positioning plate so that the second positioning plate abuts against the multiple mold boxes, and pushes the multiple mold boxes to move toward the first positioning plate at the same time until the multiple mold boxes abut against the first positioning plate, thereby aligning the edges of the mold boxes.

[0012] Optionally, the first positioning plate is an arc-shaped plate with the center facing the pressing area, and the second positioning plate is a straight plate.

[0013] By adopting the above technical solution, the second positioning plate pushes the multiple mold boxes to move toward the first positioning plate, so that the arc surface of the mold box fits with the arc surface of the first positioning plate, thereby facilitating the positioning of the mold box.

[0014] Optionally, a slide groove is provided on the stacking table, and the slide groove is slidably matched with the second positioning plate.

[0015] By adopting the above technical solution, the second positioning plate and the sliding groove are slidably matched, and the sliding groove can limit the moving direction of the second positioning plate, thereby improving the stability of the second positioning plate when moving.

[0016] Optionally, it includes a pressing plate and a force source, wherein the pressing plate is arranged in the pressing area and is slidably connected to the stacking table, and the sliding direction is the vertical direction. The force source is used to drive the pressing plate to extrude the mold box.

[0017] By adopting the above technical solution, the second positioning plate moves to align the edges of multiple mold boxes, and the force source drives the pressure plate to move downward in the vertical direction until it abuts against the top wall of the mold box, and applies pressure to the mold box, thereby pressing multiple mold boxes at the same time.

[0018] Optionally, the force source is equipped with a detection component, and the detection component is used to detect the pressure applied to the mold box by the force source through the pressure plate.

[0019] By adopting the above technical solution, when the force source applies pressure to the mold box, the production personnel can check the size of the pressure through the detection piece, thereby facilitating the control of the size of the pressure applied to the mold box.

[0020] Optionally, the side wall of the pressure plate close to the first positioning plate can abut against the side wall of the first positioning plate.

[0021] By adopting the above technical solution, the side wall of the pressing plate abuts against the side wall of the first positioning plate, so that the pressing plate can cover the top wall of the mold box, so that the top wall of the mold box is evenly stressed.

[0022] Optionally, a bracket is fixedly connected to the stacking table, the force source is installed on the top of the bracket, and the output end of the force source faces downward and is connected to the pressure plate.

[0026] Optionally, the stacking table inside the pressing area is provided with a positioning groove for placing the mold box.

[0027] By adopting the above technical solution, the production personnel place the mold box in the positioning groove, thereby facilitating the positioning of the mold box.

[0033] 3. After the second positioning plate moves to align the edges of the multiple mold boxes, the force source drives the pressing plate to move downward in the vertical direction until it abuts against the top wall of the mold box, and applies pressure to the mold box, thereby pressing the multiple mold boxes at the same time;

[0034] 4. The top wall of the mold box is formed with markings such as specifications, so that the pressure plate cannot fit with the top wall of the mold box when it abuts against the top wall of the mold box, resulting in uneven force on the top wall of the mold box. When the pressure plate moves downward, the elastic part fits with the top wall of the mold box, so that the top wall of the mold box is evenly stressed and the deformation of the top wall of the mold box when it is under pressure is reduced.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-4 This application is described in further detail.

[0041] Reference Figure 1 The mold box 1 is a container for accommodating full dentures in the hot box process. A part of the side wall of the mold box 1 is an arc surface, and the other part is a plane. The mold box 1 includes an upper cover 12 and a lower box body 13 that are plugged into each other. A raised logo 11 is formed on the side of the upper cover 12 away from the lower box body 13.

[0042] The embodiment of the present application discloses a clamping device for denture production, referring to Figure 2 The clamping device for denture production includes a stacking table 3, which is disc-shaped. The edge of the bottom wall of the stacking table 3 is fixedly connected to the supporting leg 2 around the stacking table 3. The top wall of the stacking table 3 is fixedly connected to the first positioning plate 5 in the vertical direction. The first positioning plate 5 is an arc plate and is coaxially arranged with the stacking table 3.

[0043] Reference Figure 3 and Figure 4 The pressing device for denture production includes a second positioning plate 6, which is a flat plate and is arranged in the vertical direction. A slide groove 31 is provided on the top wall of the stacking platform 3 along the radial direction of the stacking platform 3. The second positioning plate 6 slides with the slide groove 31 through a slider, so that the second positioning plate 6 can slide toward or away from the first positioning plate 5 along the length direction of the slide groove 31. A handle 62 is fixedly connected to the end of the second positioning plate 6 away from the first positioning plate 5.

[0044] Reference Figure 3A clamping area 10 is formed between the first positioning plate 5 and the second positioning plate 6. A positioning groove 32 is opened on the top wall of the stacking table 3 in the clamping area 10. The side wall of the positioning groove 32 includes an arc surface and a plane, and the arc side wall of the positioning groove 32 is coplanar with the side wall of the first positioning plate 5 facing the second positioning plate 6.

[0045] When pressing the mold box 1, the production staff places the lower box body 13 of a mold box 1 in the positioning groove 32 so that the side wall of the mold box 1 abuts against the side wall of the positioning groove 32, and then places multiple mold boxes 1 in the vertical direction in sequence above the mold box 1 in the positioning groove 32. Then, the second positioning plate 6 is pushed to move the second positioning plate 6 toward the first positioning plate 5 so that the second positioning plate 6 abuts against the plane side walls of multiple mold boxes 1, and pushes multiple mold boxes 1 to move until the curved side walls of multiple mold boxes 1 abut against the side walls of the first positioning plate 5, so that the first positioning plate 5 and the second positioning plate 6 clamp the multiple mold boxes 1 together, so that the edges of the multiple mold boxes 1 are aligned, which improves the accuracy and efficiency of the alignment of the mold boxes 1, and reduces the situation where the multiple mold boxes 1 are not aligned, causing the mold boxes 1 to be deformed due to uneven force during extrusion.

[0046] The positioning groove 32 can facilitate the positioning of the first mold box 1. The curved side wall of the positioning groove 32 is coplanar with the side wall of the first positioning plate 5, so that when multiple mold boxes 1 are abutted against the side wall of the first positioning plate 5, the curved side walls of multiple mold boxes 1 can be aligned with the curved side walls of the mold box 1 in the positioning groove 32.

[0047] The handle 62 is convenient for an operator to hold to push the second positioning plate 6 to move.

[0048] Reference Figure 2 , a bracket 4 is fixedly connected to the stacking table 3, and the bracket 4 includes two columns 41 arranged in the vertical direction and parallel to each other and a mounting plate 42 parallel to the top wall of the stacking table 3, and both ends of the mounting plate 42 are fixedly connected to the two columns 41. A force source 7 is installed on the mounting plate 42 at one end facing the stacking table 3, and the force source 7 is a jack. The output end of the force source 7 faces downward, and the moving direction is the vertical direction. A detection member 8 for detecting the force applied to the mold box 1 is installed on the force source 7. A pressure plate 9 is fixedly connected to the output end of the force source 7, and the side wall of the pressure plate 9 includes an arc surface and a plane surface. The arc surface side wall of the pressure plate 9 can be fitted with the side wall of the second positioning plate 6 facing the first positioning plate 5, and the plane side wall of the pressure plate 9 can be fitted with the side wall of the first positioning plate 5 facing the second positioning plate 6.

[0049] The first positioning plate 5 and the second positioning plate 6 jointly clamp the multiple mold boxes 1 so that the edges of the multiple mold boxes 1 are aligned. The production personnel operate the driving source to move the output end of the driving source downward and drive the pressing plates 9 to move toward each other to squeeze the multiple mold boxes 1.

[0050] The side wall of the pressing plate 9 can fit with the side wall of the first positioning plate 5 and the side wall of the second positioning plate 6 at the same time, so that the pressing plate 9 can cover the cover of the mold box 1, so that the cover is evenly stressed.

[0051] Reference Figure 2 The bottom wall of the pressing plate 9 is bonded with an elastic member 91 , and the material of the elastic member 91 is rubber.

[0052] The elastic member 91 enables the elastic member 91 to abut against the cover of the mold box 1 when the pressure plate 9 squeezes the mold box 1. The elastic member 91 deforms under the action of pressure, so that the elastic member 91 fits the cover and the raised mark 11 on the cover, thereby further improving the uniformity of the force on the cover and reducing the deformation of the mark 11 due to uneven force.

[0053] The implementation principle of a clamping device for denture production in an embodiment of the present application is as follows: a mold box 1 is placed in a positioning groove 32, and then multiple mold boxes 1 are placed on the mold box 1 in the positioning groove 32 in a vertical direction, and then the second positioning plate 6 is pushed so that the second positioning plate 6 abuts against the multiple mold boxes 1, and drives the multiple mold boxes 1 to move closer to the first positioning plate 5, so that the first positioning plate 5 and the second positioning plate 6 jointly clamp the multiple mold boxes 1, so that the edges of the multiple mold boxes 1 are aligned, and the multiple mold boxes 1 can be aligned at the same time through the cooperation of the first positioning plate 5 and the second positioning plate 6, thereby improving the efficiency and accuracy of the alignment of the mold boxes 1 and reducing the deformation of the mold boxes 1 due to uneven force during extrusion due to the misalignment of adjacent mold boxes 1.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
