Description

Technical Field

[0001] This utility model relates to the field of hot cutting knife technology, specifically to a hot cutting knife mold base for tissue paper. Background Technology

[0002] In the production of facial tissues, a facial tissue machine is used to cut the tissues. The bottom blade and the top blade of the facial tissue machine play an important role in the cutting process.

[0003] The size of the tissue box cutter needs to be selected according to the processing size of the paper. However, traditional cutter casting molds can mostly only produce cutters of the same specification and size. Different size requirements require new molds, which increases production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a hot-cutting die base for tissue paper. The die base at the bottom of the die and the die core plate used for casting the die adopt a disassembly and assembly structure design. The die core plate can be directly removed from the inside of the die base for replacement. In this way, only the die core plate needs to be processed when opening the die, which can reduce the cost and solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot-cutting die base for tissue paper, including a die base and a die core plate. The outer surface of the die base is provided with a die core groove, and the die core plate is connected to the die base through the die core groove. Locking grooves are provided around the die core groove, and guide grooves are provided between the locking grooves. The die base at the bottom of the die and the die core plate used for casting the die adopt a disassembly and assembly structure design. The die core plate can be directly removed from the inside of the die base for replacement. In this way, only the die core plate needs to be processed when opening the die, which can reduce the cost.

[0006] Furthermore, the bottom of the mold base is provided with a bottom groove, and the surface of the bottom groove is provided with a heat dissipation shaft groove. The heat dissipation shaft groove extends into the interior of the mold core groove. The bottom of the mold base adopts a hollow structure. After the blank is injected into the mold core plate, the heat will be introduced into the interior of the mold core plate. At this time, the heat dissipation shaft groove at the bottom can help the mold core plate to contact the outside air, thereby completing heat exchange and helping the internal cutting tool to cool down and form quickly.

[0007] Furthermore, a locking block is provided inside the locking groove, and the locking block is connected to the locking groove by bolts. The locking block is in contact with the mold core plate, and the mold core plate can be locked by adjusting the locking block.

[0008] Furthermore, the outer surface of the mold core plate is provided with a die groove, and a casting flow channel is provided between the die grooves, the casting flow channel extending into the interior of the die groove.

[0009] Furthermore, the core plate is provided with integrally formed positioning blocks around its perimeter.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In this utility model, the mold base at the bottom of the mold and the mold core plate used for casting tools adopt a disassembly and assembly structure design. The mold core plate can be directly removed from the inside of the mold base for replacement. In this way, only the mold core plate needs to be processed when opening the mold, which can reduce the cost consumption.

[0012] 2. In this utility model, the core plate can be locked by adjusting the locking block. At the same time, the bottom of the mold base adopts a hollow structure. After the blank is injected into the core plate, the heat will be introduced into the interior of the core plate. At this time, the heat dissipation shaft groove at the bottom can help the core plate to contact the outside air, thereby completing heat exchange and helping the internal cutting tool to cool down and form quickly, thus improving production efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To address the issue that traditional bottom die casting molds can mostly only produce bottom dies of the same size, requiring new molds for different sizes and resulting in high production costs; please refer to... Figure 1-3 The present invention provides the following solution:

[0019] The hot-cutting die base for tissue paper includes a die base 1 and a die core plate 2. The outer surface of the die base 1 is provided with a die core groove 104. The die core plate 2 is connected to the die base 1 through the die core groove 104. Locking grooves 102 are provided around the die core groove 104, and guide grooves 101 are provided between the locking grooves 102. The die base 1 at the bottom of the die and the die core plate 2 used for casting the die adopt a disassembly and assembly structure design. The die core plate 2 can be directly removed from the inside of the die base 1 for replacement. In this way, only the die core plate 2 needs to be processed when opening the die, which can reduce the cost consumption.

[0020] The bottom of the mold base 1 is provided with a bottom groove 105, and the surface of the bottom groove 105 is provided with a heat dissipation shaft groove 106. The heat dissipation shaft groove 106 extends into the interior of the mold core groove 104. A locking block 103 is provided inside the locking groove 102. The locking block 103 is connected to the locking groove 102 by bolts. The locking block 103 fits against the mold core plate 2. The locking operation of the mold core plate 2 can be completed by adjusting the locking block 103. At the same time, the bottom of the mold base 1 adopts a hollow structure. After the blank is injected into the mold core plate 2, the heat will be introduced into the interior of the mold core plate 2. At this time, the heat dissipation shaft groove 106 at the bottom can help the mold core plate 2 to contact the outside air, thereby completing heat exchange and helping the internal tool to cool down and form quickly, improving production efficiency.

[0021] The outer surface of the mold core plate 2 is provided with a die groove 201, and a casting flow channel 202 is provided between the die grooves 201. The casting flow channel 202 extends into the interior of the die groove 201. The mold core plate 2 is provided with an integrally formed positioning block 203 around its perimeter. A single mold core plate 2 can be processed by two sets of cutting tools at the same time. The positioning blocks 203 around the perimeter can be connected to the upper template through slots to ensure the docking accuracy between the flow channel and the valve nozzle.

[0022] Working principle: The mold base 1 at the bottom of the mold and the mold core plate 2 used for casting tools adopt a disassembly and assembly structure design. The mold core plate 2 can be directly removed from the mold base 1 for replacement. In this way, only the mold core plate 2 needs to be processed when opening the mold. At the same time, the bottom of the mold base 1 adopts a hollow structure. After the blank is injected into the mold core plate 2, the heat will be conducted into the interior of the mold core plate 2. At this time, the heat dissipation shaft groove 106 at the bottom can help the mold core plate 2 to contact the outside air, thereby completing heat exchange and helping the internal tools to cool down and form quickly, improving production efficiency.
