Description

Technical Field

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

[0002] Pulp molding die-cutting molds are one of the key tools in the production process of pulp molded products. They are mainly used for the precise cutting, shaping, and trimming of pulp molded products. Pulp molding die-cutting molds typically consist of an upper mold and a lower mold. The upper mold generally includes components such as a cutter and an edge-pressing device, while the lower mold contains cavities and positioning devices.

[0003] Existing pulp molding die-cutting molds utilize rounded rectangular through holes and round rods to facilitate the simultaneous control of multiple pressure rods, cutting the pulp molding material on the upper surface of the cutting table. T-shaped grooves and T-shaped sliders facilitate the movement of the pressure rods. However, these molds typically require multiple cutters. While multiple cutters increase cutting efficiency, the spacing between them is often manually adjusted, making precise adjustment difficult. Furthermore, the lack of fixing the cutters after adjustment can lead to slippage during cutting, resulting in poor-quality finished products. A search revealed that the technical solution provided by utility model application number CN202021298020.9 also suffers from the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of pulp molding die-cutting mold, which solves the problem that existing pulp molding die-cutting molds cannot adjust the spacing of multiple cutters and cannot adapt to different cutting requirements.

[0005] To achieve the above objectives, a novel pulp molding die-cutting mold is provided, comprising a base, the base having a groove inside, a blade holder slidably connected to the inner surface of the groove, a first connecting block fixedly connected to the upper surface of the blade holder, a second connecting block rotatably connected to the inside of the first connecting block, a cutter fixedly connected to the right end of the second connecting block, a cutting groove inside the blade holder, a third connecting block fixedly connected to the right end of the cutter, a through groove inside the third connecting block, and a pressure rod slidably connected to the inner surface of the through groove;

[0008] According to the novel pulp molding die-cutting mold, the number of the cutter holders is four, which are arranged in a linear array, and the lower surface of the cutter holders is slidably connected to the sliding rod.

[0009] According to the novel pulp molding die-cutting mold, the scissor-type lifting rod is rotatably connected to the sliding rod, and the sliding rod has four rods arranged in a linear array.

[0010] According to the novel pulp molding die-cutting mold, the interior of the second groove is slidably connected to the slider, and the number of sliders is two and they are distributed in a front-to-back manner.

[0011] According to the novel pulp molding die-cutting mold, a limiting block is fixedly connected to the outer surface of the slider, and the lower surface of the base is slidably connected to the limiting block.

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5 This utility model discloses a novel pulp molding die-cutting mold, comprising: a base 1, a groove 2 inside the base 1, a blade holder 3 slidably connected to the inner surface of the groove 2, the groove 2 and the blade holder 3 sliding to limit the blade holder 3 and prevent the blade holder 3 from rotating arbitrarily on the base 1; the limitation of the groove 2 ensures that the blade holder 3 moves stably horizontally as it slides with the sliding rod 12; the number of blade holders 3 is four and arranged in a linear array; a first connecting block 4 is fixedly connected to the upper surface of the blade holder 3; a second connecting block 5 is rotatably connected inside the first connecting block 4; a cutter 6 is fixedly connected to the right end of the second connecting block 5; a cutting groove 7 is provided inside the blade holder 3, the inner surface of the cutting groove 7 is adapted to the cutter 6; a third connecting block 8 is fixedly connected to the right end of the cutter 6; a through groove 9 is provided inside the third connecting block 8; a pressure rod 10 is slidably connected to the inner surface of the through groove 9; and four supports 21 are fixedly connected to the lower surface of the base 1 and arranged in a linear array.

[0026] The base 1 has a first sliding groove 11 internally connected to a sliding rod 12 internally connected to the first sliding groove 11. There are four sliding rods 12 arranged in a linear array. Each sliding rod 12 is a pivot connected internally to a scissor lift lever 14. This invention extends and fixes the pivot inside the traditional scissor lift lever 14 to the bottom of the tool holder 3. The lower surface of the tool holder 3 is slidably connected to the sliding rod 12. The base 1 has a cavity 13 internally connected to a scissor lift lever 14 internally. The scissor lift lever 14 is rotatably connected to the sliding rod 12. The base 1 has an internal cavity 13 internally connected to a scissor lift lever 14 internally connected to the sliding rod 12. The base 1 is provided with a second slide groove 15. A slider 16 is fixedly connected to the lower surface of the scissor lift rod 14. The interior of the second slide groove 15 is slidably connected to the slider 16. There are two sliders 16, which are distributed front and back. A limit block 20 is fixedly connected to the outer surface of the slider 16. The lower surface of the base 1 is slidably connected to the limit block 20. A threaded rod 17 is threadedly connected to the interior of the slider 16. A fixing block 18 is rotatably connected to the lower surface of the base 1. The interior of the fixing block 18 is rotatably connected to the threaded rod 17. A motor 19 is fixedly connected to the front surface of the fixing block 18. The output end of the motor 19 is fixedly connected to the threaded rod 17.

[0027] Working principle: By starting the motor 19, the motor 19 drives the threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the two sliders 16 to move closer and further apart. When the two sliders 16 move closer, the scissor lift rod 14 extends, causing the sliding rod 12 to move further apart, thereby causing the multiple cutters 6 to move further apart, thus controlling the spacing between the multiple cutters 6. When the two sliders 16 move further apart, the scissor lift rod 14 retracts. The retraction of the scissor lift rod 14 causes the multiple cutters 6 to move closer together, thereby reducing the spacing between the cutters 6. The pulp molded material is placed on the cutter holder 3 through the multiple cutters 6. The pressure rod 10 passes through the inside of the through groove 9. Pressing the pressure rod 10 can drive the multiple cutters 6 to cut the pulp molded material, improving the efficiency of operation. Moreover, the pressure rod 10 does not affect the movement of the cutter holder 3.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
