Description

Technical Field

[0001] This utility model relates to the field of pulp molding technology, and in particular to a pulp molding mold. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper as raw material to create paper products of a certain shape using special molds on a molding machine. To solidify the pulp molding, a heating device is used to evaporate the moisture it contains.

[0003] Currently, although a wide variety of pulp molding dies can be used to manufacture paper products of various shapes, most dies employ a one-piece design, meaning that each die is limited to producing paper products of a single shape. This limitation not only reduces the practicality of the dies but also significantly increases the cost burden of producing paper products of different shapes.

[0004] Therefore, a pulp molding die is needed to solve the above problems. Utility Model Content

[0030] Reference Figure 1 - Figure 6 As one embodiment of this utility model, a pulp molding die is provided, comprising:

[0031] The main unit 100 includes a workbench 101. A lower mounting block 102 is fixedly connected to the upper end of the workbench 101. A lower mold 103 is provided inside the lower mounting block 102. Two threaded blocks 1031 are symmetrically fixedly connected to both sides of the lower mold 103. Two fixing screws 104 are meshed in the inner wall of the lower mounting block 102. Multiple support rods 105 are fixedly connected to the upper end of the workbench 101. A mounting frame 106 is fixedly connected to the upper end of the multiple support rods 105. A hydraulic telescopic rod 107 is fixedly embedded in the inner wall of the mounting frame 106. An upper mounting block 108 is fixedly connected to the telescopic end of the hydraulic telescopic rod 107. An upper mold 109 is provided at the lower end of the upper mounting block 108. A fixing block 1091 is fixedly connected to the upper end of the upper mold 109. Multiple slots are symmetrically opened on both sides of the fixing block 1091.

[0032] The mounting mechanism 200 is configured in two groups. Each group of mounting mechanisms 200 includes a servo motor 201 and a straight cylinder 202. Each straight cylinder 202 is fixedly installed in the mounting frame 106. The output end of each servo motor 201 passes through the straight cylinder 202 and is fixedly connected to a ball screw 203. Each ball screw 203 is meshed with a screw sleeve 204. Two push plates 205 are fixedly connected to both sides of each screw sleeve 204. Two push blocks 206 are fixedly connected to the opposite end of each push plate 205. The other ends of each pair of push blocks 206 are fixedly connected to a clamping plate 207. The opposite ends of multiple clamping plates 207 abut against the clamping groove.

[0033] By rotating the fixing screw 104 and separating it from the threaded block 1031, the lower mold 103 can be removed for replacement. The servo motor 201 and the ball screw 203 drive the screw sleeve 204 to move in opposite directions. The screw sleeve 204, the push plate 205 and the push block 206 drive the clamping plate 207 to move in opposite directions and disengage from the clamping slot, thereby disassembling and replacing the upper mold 109. Moreover, the installation is relatively convenient. Therefore, the problem of molds that cannot be replaced is solved, so that it is not limited to the production of paper products of a single shape, improving the practicality of the mold and significantly reducing the cost burden of producing paper products of different shapes.

[0034] Two sliding holes are symmetrically opened on both sides of the two straight cylinders 202. The opposite ends of the multiple push plates 205 pass through the sliding holes and are slidably connected in the sliding holes. The push plates 205 and push blocks 206 drive the card plate 207 to move.

[0035] The two fixing screws 104 are threaded to the threaded block 1031 at opposite ends, and the two ball screws 203 are rotatably connected to the inner wall of the straight cylinder 202. The lower mold 103 is fixed by the fixing screws 104 and the threaded block 1031.

[0036] The lower mounting block 102 has multiple symmetrically arranged limiting grooves at its upper end, and the upper mounting block 108 has multiple limiting plates 110 that match the limiting grooves at its lower end. The setting of the limiting plates 110 and the limiting grooves facilitates the positioning of the mold.

[0037] The upper mounting block 108 has a controller fixedly mounted on its front side. Both servo motors 201 are electrically connected to the controller, and the controller can be configured to control the operation of the servo motors 201.

[0038] The lower ends of the two servo motors 201 are fixedly connected to motor mounts, and one end of each motor mount is fixedly connected to the upper mounting block 108. The motor mounts support the servo motors 201.

[0039] Working principle: By rotating the fixing screw 104 and separating it from the threaded block 1031, the lower mold 103 can be removed for replacement. Further, the servo motor 201 is started, and its output drives the ball screw 203 to rotate. The ball screw 203 drives the screw sleeve 204 to move in opposite directions, which in turn drives the push plate 205 to move in opposite directions. The push plate 205 and push block 206 then drive the clamping plate 207 to move in opposite directions and disengage from the clamping slot, thus allowing the upper mold 109 to be disassembled and replaced. Installation is relatively convenient, thus solving the problem of molds not being replaceable. This allows the mold to be used for producing more than just single-shaped paper products, improving its practicality and significantly reducing the cost burden of producing paper products of different shapes.
