Description

Technical Field

[0001] The utility model relates to a multilayer plate mold locking device, belonging to the technical field of molds. Background Art

[0002] When the mold is opened, it is easy to lift the middle template before the upper template completely leaves the middle template. In the process of lifting, it is easy to hit the product and damage the mold. In addition, the premature loosening of the middle template can easily affect the stability of product quality. Therefore, in order to ensure the integrity of the mold and the stability of product quality, manual operation is required, that is, inserting an iron rod to clamp the middle template to ensure that the middle plate will not loosen in advance, but this will greatly waste time and significantly reduce production efficiency. A flexible opening and locking device for rubber molds is disclosed in the prior art, and its application number is 201921421821.7. This locking mechanism is a manual positioning pin and a fixed block that cooperate to lock the middle template and the lower template, thereby ensuring that the middle template and the lower template are interlocked; after the upper template is opened, the manual positioning pin is pulled out, and the middle template is manually moved away; but this structure is relatively complicated and inconvenient to operate, so a better way is needed to ensure that the middle plate of the mold will not loosen prematurely, and at the same time ensure that production efficiency will not be reduced. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model cooperates with a fixed shaft, a fixed column and a locking mold piece. When the locking mold piece is buckled on the fixed column, the middle mold plate and the lower mold plate cannot be automatically separated, preventing the middle mold plate from rising and then falling down to crush the product.

[0004] The technical solution adopted by the utility model is a multi-layer plate mold locking device, comprising an upper template, a middle template and a lower template which are arranged in sequence from top to bottom, the side wall of the middle template is provided with a fixed shaft, the side wall of the lower template is provided with a fixed column, and the locking plate is provided with an axial hole for the fixed shaft to pass through. In the mold closing state, one end of the locking plate is buckled on the fixed column. When the middle template needs to be separated from the lower template, the locking plate rotates with the fixed shaft as the axis under the action of force and is separated from the fixed column.

[0005] Furthermore, the locking device also includes a connecting plate A and a spring for resetting the locking plate. The connecting plate A is fixed to the side wall of the middle template and the connecting plate A is lower than the height of the fixed axis in the vertical height of the middle template. One end of the spring is connected to the connecting plate A, and the other end of the spring is connected to the side of the locking plate.

[0006] Furthermore, the locking piece is divided into a pressing part, a rotating part and a hook part from top to bottom. The pressing part, the rotating part and the hook part are integrated. There is a bending angle between the pressing part and the rotating part. The axial hole is located in the rotating part. The hook part has a slot, and the slot is buckled on the fixed column when the mold is in the closed state.

[0007] Furthermore, the mold locking device also includes a connecting plate B and a baffle. The connecting plate B is symmetrically arranged on the side wall of the middle mold plate with the connecting plate A as the symmetry axis. The two ends of the baffle are respectively fixed on the connecting plate A and the connecting plate B. The fixed axis passes through the middle of the baffle. The connecting plate A, the connecting plate B and the baffle constitute the flipping space of the mold locking plate. The mold locking plate runs through the flipping space. The connecting plate B is used to limit the counterclockwise rotation angle of the mold locking plate.

[0008] Furthermore, the side wall of the middle template is also provided with a handle.

[0009] Furthermore, the handle is in a downwardly curved arc shape, and the pressing portion is located above the handle.

[0010] The utility model discloses a multilayer plate mold locking device, which has the beneficial effect that compared with the prior art, through the cooperation of a fixed shaft, a fixed column and a locking plate, when the locking plate is buckled on the fixed column, the middle plate and the lower plate are interlocked, which solves the problem that the middle plate is lifted up by the upper plate when the mold is opened, so that the middle plate is easy to hit the product and damage the mold when it falls; at the same time, the position of the handle and the pressing part is arranged to facilitate the operator to take out the middle plate, and the connecting plate A and the spring are arranged so that the locking plate is automatically reset after the pressing part is released.

[0017] In order to further understand the content of the utility model, this technical solution is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1:

[0019] like Figures 1-2 As shown, this embodiment provides a multilayer plate mold locking device, including an upper template 1, a middle template 2, and a lower template 3 arranged in sequence from top to bottom, the side wall of the middle template 2 is provided with a fixed shaft 4, the side wall of the lower template 3 is provided with a fixed column 5, and the locking plate 10 is provided with an axis hole 121 for the fixed shaft 4 to pass through. In the mold closing state, one end of the locking plate 10 is snapped on the fixed column 5. When the middle template 2 and the lower template 3 need to be separated, the locking plate 10 rotates with the fixed shaft 4 as the axis under the action of force and separates from the fixed column 5. The locking device also includes a connecting plate A20 and a spring 6 for resetting the locking plate 10. The connecting plate A20 is fixed to the side wall of the middle template 2 and the connecting plate A20 is lower than the height of the fixed shaft 4 in the vertical height of the middle template 2. One end of the spring 6 is connected to the connecting plate A20, and the other end of the spring 6 is connected to the side of the locking plate 10. The locking plate 10 is divided into a pressing part 11, a rotating part 12 and a barb part 13 from top to bottom. The pressing part 11, the rotating part 12 and the barb part 13 are integrated. There is a bending angle between the pressing part 11 and the rotating part 12. The shaft hole 121 is located in the rotating part 12. The barb part 13 has a slot 131. When in the mold closing state, the slot 131 is buckled on the fixing column 5, and the other end of the spring 6 is connected to the side of the rotating part 12. The side wall of the middle mold plate 2 is also provided with a handle 8 to facilitate the removal of the middle mold plate 2.

[0020] Embodiment 2:

[0021] Different from Example 1, Figure 2 and 3The clamping device shown also includes a connecting plate B21 and a baffle 7. The connecting plate B21 is symmetrically arranged on the side wall of the middle mold plate 2 with the clamping plate 10 as the symmetry axis and the connecting plate A20. The two ends of the baffle 7 are respectively fixed on the connecting plate A20 and the connecting plate B21. The fixed shaft 4 passes through the baffle 7. The connecting plate A20, the connecting plate B21 and the baffle 7 constitute the flipping space of the clamping plate 10. The clamping plate 10 passes through the flipping space and cooperates with the middle mold plate 2 through the baffle 7 to prevent the clamping plate 10 from shaking on the fixed shaft 4. The connecting plate B21 is used to limit the counterclockwise rotation angle of the clamping plate 10 to prevent the clamping plate 10 from being inverted due to excessive flipping angle. The handle 8 is in the shape of a downward curved arc, and the pressing portion 11 is located above the handle 8.

[0022] During actual application, in the mold closing state, the card slot 131 of the hook portion 13 is stuck on the fixed column 5, realizing the interlocking of the middle template 2 and the lower template 3, solving the problem that the middle template 2 is lifted up by the upper template 1 when the mold is opened, making it easy for the middle template 2 to hit the product and damage the mold when it falls; when opening the mold, hold the handle 8 with the palm of the hand, press the pressing part 11 with the thumb to make the locking plate 10 rotate counterclockwise with the fixed axis 4 as the axis, and the hook portion 13 is separated from the fixed column 5, that is, the middle template 2 is unlocked from the lower template 3, and the handle 8 is pulled to take out the middle template 2 and the locking plate 10. When the middle template 2 is placed on the lower template 3, the hand moves the pressing part 11 downward. When the hand is released, the spring 6 resets and drives the locking plate 10 to reset, so that the hook portion 13 is engaged with the fixed column 5, preventing the locking plate 10 from rotating and affecting the operation and causing personal injury.
