Description

Technical Field

[0001] The utility model relates to a molding die for the cylindrical body of paper containers such as paper cups and paper bowls. Background Art

[0002] Paper containers such as paper cups or paper bowls (collectively referred to as paper cups for convenience) and cup sleeves for outer cups rely on the forming mold. The paper sheets are clamped to the forming mold above by the cup clamping device (such as left clamp, right clamp, top block, etc.). The left and right sides of the paper sheets overlap to form overlapping edges, which are then pressed down by the die head of the ultrasonic device to heat and bond them.

[0003] During continuous operation, the forming mold is constantly heated, which can easily cause the forming mold and the paper tube to stick together, making it difficult to smoothly release the paper tube from the mold. Furthermore, for some paper materials (i.e., paper sheets), increasing the power of the ultrasonic device to ensure that the overlapping edges are heated and bonded to form the tube body will cause the forming mold to heat up even more. This can lead to more serious problems for paper tubes made of, for example, PLA paper, double-coated paper, and coated paper, which can stick to the forming mold. Utility Model Content

[0004] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a barrel forming mold with a cooling function.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: a barrel forming mold with a cooling function, including a mold body, characterized in that: the mold body is connected to a water receiving seat, a longitudinal channel is provided on the mold body, a first water receiving port, a second water receiving port, a water flow channel and a longitudinal water flow pipe are provided on the water receiving seat, the water flow channel is connected to the longitudinal channel, a partition is provided between the first water receiving port and the water flow channel, a longitudinal water flow pipe is provided on the partition, the first water receiving port is connected to the rear end of the longitudinal water flow pipe, the front end of the longitudinal water flow pipe passes through the water flow channel and extends into the longitudinal channel, and the second water receiving port is connected to the water flow channel.

[0006] The following various optimizations or supplementary explanations can be made on the above technical solutions respectively.

[0007] For example, the first water inlet is arranged longitudinally, the water passage is arranged longitudinally, the first water inlet, the longitudinal water pipe and the longitudinal channel are arranged coaxially, and the second water inlet is arranged radially.

[0008] Further optimization is performed, where the longitudinal water pipe extends into the end of the longitudinal channel; a water return gap is formed between the front end of the longitudinal water pipe and the end of the longitudinal channel.

[0009] There are water gaps between the longitudinal water pipe and the longitudinal channel, and between the longitudinal water pipe and the water channel.

[0010] For another example, the longitudinal channel and the water receiving seat are screwed or tightly connected through threads.

[0011] In addition, the longitudinal channel is centrally arranged relative to the mold body.

[0012] In addition, the mold body also includes a positioning block for matching the positioning hole of the support plate connected to the frame, and the positioning block is located on the rear side of the mold body; the mold body also has a mounting seat, which is connected to the support plate.

[0013] For another example, the positioning block is centrally arranged relative to the mold body, and the water receiving seat is installed and connected to the positioning block and is connected to the longitudinal channel.

[0014] For example, the first water inlet is located at the rear side of the water receiving seat, the water passage is located at the front of the water receiving seat; the longitudinal channel is located at the rear of the mold body, and the end of the longitudinal channel is arranged rearward.

[0015] The beneficial effect of the present invention is that, in the barrel forming mold with cooling function, a water channel for coolant to circulate in sequence (either positive or reverse) is formed by the first water inlet, the longitudinal water pipe, the longitudinal channel, the water channel and the second water inlet, so as to cooperate with the cooling of the mold body and make it have a better cooling function. The structure of the mold body is relatively simple and only the longitudinal channel (single-hole structure) needs to be set to cooperate. The processing is relatively simpler and the risk of water leakage is reduced. Moreover, only one connection position is required between the water receiving seat and the mold body, which further reduces the risk of water leakage. With the cooling function, the problem of paper tube sticking to the mold body can be reduced, the problem of continuous increase in the temperature of the forming mold can be avoided, and the demolding of the paper tube will be smoother. With the cooling function, the overlapped edges of the paper tube can be bonded faster and firmly to meet the requirements of high-speed production. During assembly, it is only necessary to connect the prepared water receiving seat to the mold body. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the implementation of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Referring to the accompanying drawings, in an example of this embodiment, a cylinder forming mold with a cooling function includes a mold body 1. When used for forming paper cups or paper bowls, the paper sheets are surrounded by the mold body 1 to form the cylinder.

[0025] The mold body 1 is connected to a water receiving seat 2, which is provided with a longitudinal channel 10. The water receiving seat 2 is provided with a first water receiving port 21, a second water receiving port 22, a water flow channel 23, and a longitudinal water flow pipe 20. The water flow channel 23 is connected to the longitudinal channel 10. A baffle 24 is provided between the first water receiving port 21 and the water flow channel 23. The baffle 24 can separate the first water receiving port 21 from the water flow channel 23. The longitudinal water flow pipe 20 is connected to the baffle 24. A through hole can be provided on the baffle 24 for the longitudinal water flow pipe 20 to cooperate with and assemble. The first water receiving port 21 is connected to the rear end of the longitudinal water flow pipe 20. The front end of the longitudinal water flow pipe 20 passes through the water flow channel 23 and extends into the longitudinal channel 10. The second water receiving port 22 is connected to the water flow channel 23.

[0026] In the barrel forming mold with cooling function, a water channel for the coolant to circulate in sequence (either positive or reverse order) is formed by the first water inlet 21, the longitudinal water pipe 20, the longitudinal channel 10, the water channel 23 and the second water inlet 22, so as to cooperate with the cooling of the mold body 1 and make it have a better cooling function. The structure of the mold body 1 is relatively simple and only the longitudinal channel 10 (single-hole structure) needs to be set to cooperate. The processing is relatively simpler and the risk of water leakage is reduced. Moreover, only one connection position is required between the water receiving seat 2 and the mold body 1, which further reduces the risk of water leakage. With the cooling function, the problem of the paper tube sticking to the mold body 1 can be reduced, the problem of the temperature of the forming mold constantly rising can be avoided, and the demoulding of the paper tube will be smoother. With the cooling function, the overlapped edges of the paper tube can be bonded and shaped faster to meet the requirements of high-speed production. During assembly, it is only necessary to connect the prepared water receiving seat 2 to the mold body 1 accordingly.

[0027] The following optimization or further explanation may be performed based on the above embodiments.

[0028] For example, the first water inlet 21 is longitudinally arranged (longitudinal direction refers to the front-to-back axis, the same applies below), the water passage 23 is longitudinally arranged, the first water inlet 21, the longitudinal water passage 20, and the longitudinal channel 10 are coaxially arranged, and the second water inlet 22 is radially arranged. This results in a relatively compact structure, facilitating axial insertion during assembly. The first water inlet 21 and the second water inlet 22 are generally configured to connect to an external waterway connector.

[0029] The longitudinal water pipe 20 extends into the distal end of the longitudinal channel 10. The relative position of the extension can be adjusted by adjusting the length of the longitudinal water pipe 20 or the depth of the longitudinal channel 10, allowing the longitudinal water pipe 20 (front end) to extend as far as possible into the longitudinal channel 10 for more adequate cooling. Furthermore, a return water gap is formed between the front end of the longitudinal water pipe 20 and the distal end of the longitudinal channel 10, ensuring water circulation and adequate cooling. For example, the coolant flows sequentially through the longitudinal water pipe 20, the return water gap, and the longitudinal channel 10 to form a flow path.

[0030] A water gap is provided between the longitudinal water pipe 20 and the longitudinal hole 10, and between the longitudinal water pipe 20 and the water passage 23. The size of the water gap can be set by adjusting the diameter of the water pipe. The longitudinal hole 10 and the water passage 23 are respectively surrounded by the longitudinal water passage 23.

[0031] The first water inlet 21, the longitudinal water pipe 20, the longitudinal channel 10, the water passage 23, and the second water inlet 22 are sequentially connected to form a waterway for coolant flow. The flow direction can be forward or reverse. For example, coolant can be introduced from the first water inlet 21, pass through the waterway, and then be discharged from the second water inlet 22, which provides a good flow and facilitates cooling. Of course, reverse flow is also possible.

[0032] In addition, the longitudinal channel 10 is connected to the water receiving seat 2 by screw-fastening or tight fitting. For example, in the figure, the use of screw-fastening and screw-fitting is relatively convenient for assembly and disassembly. The port of the longitudinal channel 10 is provided with an internal thread, and the water receiving seat 2 is provided with an external thread, which is screwed into the internal thread. The outer ring of the water receiving seat 2 can also be provided as a wrench fitting part. The longitudinal channel 10 is centered relative to the mold body 1, and the cooling effect is relatively balanced. The first water inlet 21 is located at the rear side of the water receiving seat 2, the water passage 23 is located at the front of the water receiving seat 2, and the longitudinal channel 10 is located at the rear of the mold body 1. The port of the longitudinal channel 10 is set to the rear, which is not only convenient for connection, but also frees up the front side of the mold body 1 for connection of other structures.

[0033] In addition, the mold body 1 also includes a positioning block 11, which is located on the rear side of the mold body 1. The support plate on the equipment frame has a positioning hole, and the positioning block 11 can be matched and connected in the positioning hole. The positioning block 11 can be a square block or a square block with chamfered corners, which facilitates the rapid installation and setting of the mold body 1. The mold body 1 also has a mounting seat 12, which is connected to the support plate and can be connected with fasteners to facilitate the replacement of specifications or maintenance. The positioning block 11 is set centrally relative to the mold body 1, and the water receiving seat 2 is installed and connected to the positioning block 11 and connected to the longitudinal channel 10, making the structure relatively more compact.
