[0022] Furthermore, the transmission end also includes a second transmission member, which is cross-arranged with the first transmission member; the driving member includes a second driving member, and the state of the locking end after passing through the through hole is the first state, and the second driving member is used to drive the second transmission member and drive the locking end to rotate back to the first state.

[0023] The beneficial effect of adopting the above further solution is: by providing a second transmission member and a second driving member, the second transmission member drives the locking end to rotate back to the first state, that is, the mold frame is opened.

[0024] On the basis of the above technical solution, the present invention can also be improved as follows.

[0025] Furthermore, the first transmission member and the second transmission member are arranged perpendicular to each other.

[0026] The beneficial effect of adopting the above further solution is that the two transmission members are perpendicular to each other, which facilitates the drive setting of the two driving members and the transmission member.

[0027] On the basis of the above technical solution, the present invention can also be improved as follows.

[0028] Furthermore, the surface where the second transmission member contacts the second driving member is the second transmission member contact surface, the distance between the rotation centerline of the connecting rod and the second transmission member contact surface is the second driving distance, and the distance between the top end of the second driving member and the rotation centerline of the connecting rod is equal to the second driving distance.

[0056] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0057] The structural diagram of the locking mechanism of the mold device of the utility model is shown in FIG. Figures 1 to 12 .

[0058] A mold device locking mechanism is used to lock the first mold frame and the second mold frame. As shown in the figure, the first hinge end 11 of the first mold frame and the second hinge end 21 of the second mold frame are hingedly connected, and a rotating shaft 33 is provided at the connection. The first mold frame and the second mold frame are used to install the template, that is, the back of the template is fixed to the first mold frame and the second mold frame by screw connection or the like.

[0059] It includes a locking member 4 and a driving member, the locking member 4 includes a connecting rod 43, the two ends of the connecting rod 43 are respectively a transmission end and a locking end 44, the transmission end is rotatably connected to the first open end 12 of the first mold frame; the second open end 22 of the second mold frame is provided with a through hole 23, the locking end 44 passes through the through hole 23, and the through hole 23 matches the connecting rod 43 and the locking end 44.

[0060] The driving member is arranged opposite to the first open end 12 of the first mold frame. When the mold frame moves past the driving member, the driving member drives the transmission end and drives the locking end 44 to rotate, and the locking end 44 locks the mold frame.

[0061] As shown in the figure, the locking end 44 is in the shape of a rectangular parallelepiped as a whole, and the height direction of the locking end 44 is parallel to the axial direction of the through hole 23. The length direction of the locking end 44 is greater than the outer diameter of the connecting rod 43, and the width direction of the locking end 44 is less than the outer diameter of the connecting rod 43.

[0062] As shown in the figure, the locking end 44 passes through the through hole 23 and matches it, that is, the through hole 23 is also set to be a circular hole in the middle and extends to both ends to form a rectangular hole shape, that is, a space to accommodate the two ends of the locking end 44 to pass through.

[0063] In this embodiment, as shown in the figure, the transmission end is located below the figure, and the transmission end includes a first transmission member 41, and the first transmission member 41 is arranged in parallel with the locking end 44. Figure 2 As shown in the figure, the locking end 44 is parallel to the first transmission member 41 and is consistent with the length direction of the through hole 23. A second transmission member 42 is also included, and the second transmission member 42 is arranged crosswise with the first transmission member 41. In the figure, the second transmission member 42 is perpendicularly crossed with the first transmission member 41, that is, the second transmission member 42 and the locking end 44 are also perpendicular.

[0064] Among them, Figures 2 to 5 As shown, the driving member includes a first driving member 5, which is fixedly arranged and used to drive the first transmission member 41; the surface where the first transmission member 41 contacts the first driving member 5 is the first transmission member contact surface, the distance between the rotation center line of the connecting rod 43 and the first transmission member contact surface is the first driving distance, and the distance between the top end of the first driving member 5 and the rotation center line of the connecting rod 43 is equal to the first driving distance.

[0065] For a detailed schematic diagram of the distance between the top end of the first driving member 5 and the rotation center of the connecting rod 43, see Figures 17 to 18 , these two figures are working state diagrams of the driving member and the transmission member during the locking operation of the first embodiment, such as Fig.17 As shown, the surface where the first transmission member 41 contacts the first driving member 5 is the first transmission member contact surface. The first transmission member contact surface is shown on the right side of the first transmission member 41. The distance between the rotation center line of the connecting rod 43 and the first transmission member contact surface is the first driving distance A; the distance between the top of the first driving member 5 and the rotation center line of the connecting rod 43 is B. As shown in the figure, in this example, the distance B is equal to the distance A. Fig.18 As shown, after the first driving member 5 drives the first transmission member 41, the first transmission member 41 rotates 90 degrees in the clockwise direction as shown in the figure.

[0066] The working process of the locking mechanism of the mold device in the first embodiment during locking operation is shown in FIG. Figures 2 to 5 ,like Figure 2As shown, the first driving member 5 is arranged in the direction opposite to the first open end 12 of the first mold frame, that is, to the right of the first open end 12 in the figure. The positional relationship between the top of the first driving member 5 and the first transmission member 41 can be seen from the dotted line in the figure. The first driving member 5 is substantially the same height as the first transmission member 41 in the horizontal direction, and the distance between the top of the first driving member 5 and the rotation center line of the connecting rod 43 is equal to the first driving distance. The entire mold frame moves toward the first driving member 5 until the first transmission member 41 contacts the first driving member 5, that is, Figure 3 When the entire mold frame continues to move forward, the first drive member 5 drives the first transmission member 41 to rotate, the first transmission member 41 drives the locking end 44 to rotate, so that the first mold frame and the second mold frame are locked and closed, such as Figure 4 The entire mold frame continues to move forward and away from the first driving member 5, as shown. Figure 5 In the mold device locking mechanism of this embodiment, the mold frame is set on the continuously moving mechanism, and the fixed first driving member 5 and the locking member 4 are linked to realize the automatic locking and tightening of multiple mold frames.

[0067] The first embodiment of the locking mechanism of the mold device also has the function of opening the mold frame. The working process of opening the mold frame is shown in FIG. Figures 6 to 10 In this example, the entire mold frame is flipped during the chain drive movement, that is, the drive end is located above the figure, and the drive end also includes a second drive member 42, and the second drive member 42 is cross-arranged with the first drive member 41; the drive member includes a second drive member 6, and the state after the locking end 44 passes through the through hole 23 is the first state, and the second drive member 6 is used to drive the second drive member 42 and drive the locking end 44 to rotate back to the first state.

[0068] The contact surface between the second transmission member 42 and the second driving member 6 is the second transmission member contact surface, the distance between the rotation center line of the connecting rod 43 and the second transmission member contact surface is the second driving distance, and the distance between the top end of the second driving member 6 and the rotation center line of the connecting rod 43 is equal to the second driving distance.

[0069] For a detailed schematic diagram of the distance between the top end of the second driving member 6 and the rotation center of the connecting rod 43, see Figures 21 to 22 , these two figures are working state diagrams of the driving member and the transmission member when the first embodiment is turned on. Fig.21 As shown, the surface where the second transmission member 42 contacts the second drive member 6 is the second transmission member contact surface. The second transmission member contact surface is shown on the left side of the second transmission member 42. The distance between the rotation center line of the connecting rod 43 and the second transmission member contact surface is the second drive distance C; the distance between the top of the second drive member 6 and the rotation center line of the connecting rod 43 is D. As shown in the figure, in this example, the distance D is equal to the distance C. Fig. 22As shown, after the second driving member 6 drives the second transmission member 42, the second transmission member 42 rotates 90 degrees in the counterclockwise direction as shown in the figure.

[0070] The working process of the locking mechanism of the mold device in the first embodiment when opening the work is shown in FIG. Figures 7 to 10 ,like Figure 7 As shown, the second driving member 6 is arranged in the direction opposite to the first open end 12 of the first mold frame, that is, on the left side of the first open end 12 in the figure. The positional relationship between the top of the second driving member 6 and the second transmission member 42 can be seen from the dotted line in the figure. The second driving member 6 is substantially the same height as the second transmission member 42 in the horizontal direction, and the distance between the top of the second driving member 6 and the rotation center line of the connecting rod 43 is equal to the second driving distance. The entire mold frame moves toward the second driving member 6 until the second transmission member 42 contacts the second driving member 6. Figure 8 When the entire mold frame continues to move forward, the second driving member 6 drives the second transmission member 42 to rotate, and the second transmission member 42 drives the locking end 44 to rotate, so that the locking end 44 rotates back to the first state (the first state is the state after the locking end 44 passes through the through hole 23 is the first state), such as Fig. 9 The entire mold frame continues to move forward and away from the second driving member 6, as shown. Fig.10 In the mold device locking mechanism of this embodiment, the mold frame is arranged on the continuously moving mechanism, and the fixed second driving member 6 and the locking member 4 are linked to realize the automatic opening function of multiple mold frames.

[0071] The working process of the locking mechanism of the mold device in the second embodiment of the locking operation is shown in FIG. Figures 11 to 13 , compared with the first embodiment, the difference is that the distance between the top of the first driving member 5 and the rotation center line of the connecting rod 43 is not equal to the first driving distance, such as Fig.19 As shown, the surface where the first transmission member 41 contacts the first driving member 5 is the first transmission member contact surface. The first transmission member contact surface is shown on the right side of the first transmission member 41. The distance between the rotation center line of the connecting rod 43 and the first transmission member contact surface is the first driving distance A; the distance between the top of the first driving member 5 and the rotation center line of the connecting rod 43 is B. As shown in the figure, in this example, the distance B is greater than the distance A. Fig. 20 As shown, after the first driving member 5 drives the first transmission member 41, the first transmission member 41 rotates in the clockwise direction as shown in the figure by an angle less than 90 degrees.

[0072] Working process see Figures 11 to 13 ,like Fig.11As shown, the first driving member 5 is arranged in the direction opposite to the first open end 12 of the first mold frame, that is, to the right of the first open end 12 in the figure. The positional relationship between the top of the first driving member 5 and the first transmission member 41 can be seen from the dotted line in the figure. The first driving member 5 is substantially consistent with the first transmission member 41 in the horizontal direction, and the distance between the top of the first driving member 5 and the rotation center line of the connecting rod 43 is greater than the first driving distance. The entire mold frame moves toward the first driving member 5, moves to the first transmission member 41 and contacts the first driving member 5, and the first driving member 5 drives the first transmission member 41 to rotate, and the first transmission member 41 drives the locking end 44 to rotate, so that the first mold frame and the second mold frame are locked and closed, as shown in FIG. Fig.12 The entire mold frame continues to move forward and away from the first driving member 5, as shown. Fig.13 In the mold device locking mechanism of this embodiment, the mold frame is set on the continuously moving mechanism, and the fixed first driving member 5 and the locking member 4 are linked to realize the automatic locking and tightening of multiple mold frames.

[0073] The working process of the second embodiment of the locking mechanism of the mold device when opening is shown in FIG. Figures 14 to 16 , the distance between the top of the second driving member 6 and the rotation center line of the connecting rod 43 is equal to the second driving distance, such as Fig.23 As shown, the surface where the second transmission member 42 contacts the second drive member 6 is the second transmission member contact surface. The second transmission member contact surface is shown on the left side of the second transmission member 42. The distance between the rotation center line of the connecting rod 43 and the second transmission member contact surface is the second drive distance C; the distance between the top of the second drive member 6 and the rotation center line of the connecting rod 43 is D. As shown in the figure, in this example, the distance D is equal to the distance C. Fig.24 As shown, after the second driving member 6 drives the second transmission member 42, the second transmission member 42 rotates in the counterclockwise direction shown in the figure and causes the locking end 44 to rotate back to the first state.

[0074] The working process of the second embodiment of the locking mechanism of the mold device when opening is shown in FIG. Figures 14 to 16 ,like Fig.14As shown, the second driving member 6 is arranged in the direction opposite to the first open end 12 of the first mold frame, that is, on the left side of the first open end 12 in the figure. The positional relationship between the top of the second driving member 6 and the second transmission member 42 can be seen from the dotted line in the figure. The second driving member 6 is substantially consistent with the height of the second transmission member 42 in the horizontal direction 43, and the distance between the top of the second driving member 6 and the rotation center line of the connecting rod is equal to the second driving distance. The entire mold frame moves toward the second driving member 6 until it contacts the second transmission member 42 and the second driving member 6. When the entire mold frame continues to move forward, the second driving member 6 drives the second transmission member 42 to rotate, and the second transmission member 42 drives the locking end 44 to rotate, so that the locking end 44 rotates back to the first state (the first state is the state after the locking end 44 passes through the through hole 23). Fig.15 The entire mold frame continues to move forward and away from the second driving member 6, as shown. Fig.16 As shown. In the mold device locking mechanism of this embodiment, the mold frame is set on the continuously moving mechanism, and the fixed second driving member 6 is linked with the locking member 4 to realize the automatic opening function of multiple mold frames. It should be noted that during the opening process, under the condition that the distance between the top of the second driving member 6 and the rotation center line of the connecting rod 43 is equal to the second driving distance, it is necessary to ensure that the second driving member 6 and the contact surface of the second transmission member can contact each other.

[0075] In a specific embodiment, the surface of the locking end 44 connected to the connecting rod 43 is an arc surface with both ends tilted upward. By providing a transitional arc surface structure, a transition effect is played during the rotation of the locking end 44, facilitating the rotation of the locking end 44.

[0076] In a specific embodiment, the first driving member 5 and the second driving member 6 can be fixedly arranged on a corresponding frame or other positions to realize driving of the transmission end.

[0077] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
