Description

Technical Field

[0001] This utility model belongs to the field of extrusion die technology, specifically relating to a plastic extrusion die with a cooling structure. Background Technology

[0002] In processing, powdered or granular polymers are typically added to the extruder barrel. Under the action of the screw or plunger, the polymer moves forward along the screw channel or barrel and gradually melts into a viscous fluid. Then, it passes through a plastic extrusion die at the end of the barrel to form a continuous body similar in shape to the die orifice. Finally, after cooling and solidification, it can be molded into products of the desired shape, such as various plastic pipes, rods, sheets, PVC doors and windows, films, decorative skirting boards, etc.

[0003] In the use of existing plastic extrusion molds, when assembling the multiple modules that make up the mold, the modules are gradually assembled according to the assembly requirements. This is done by gradually fitting the modules together and aligning the mounting holes between the modules before inserting the screw. However, the alignment of the mounting holes can cause some obstruction, making it difficult for the operator to confirm the position of the mounting holes. This results in some inconvenience when aligning the mounting holes. To address this issue, this utility model proposes a plastic extrusion mold with a cooling structure. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic extrusion mold with a cooling structure, comprising multiple modules, each module having an orifice of different sizes on its inner side, and a locking mechanism between the modules. The locking mechanism consists of symmetrically arranged limiting components and symmetrically arranged fixing components. The limiting components consist of a limiting rotating groove, a limiting rotating block, and a silicone seat. The limiting rotating groove is located on the top surface of the module, the limiting rotating block is fixed to the bottom end of the module, and the silicone seat is fixed to the inner side of the end of the limiting rotating groove. The fixing components consist of a fixing block and a fixing groove. The fixing block is fixed to the bottom edge of the module, the fixing groove is located at the top edge of the module, and the fixing block engages with the inner side of the fixing groove.

[0006] Preferably, the four corners of the fixing block are inclined, and the two sides of the fixing groove are inclined.

[0007] Preferably, the width of the fixing groove is greater than the width of the fixing block, and the outer surface of the fixing block is at the same level as the side of the module.

[0008] Preferably, the cross-section of the limiting rotation groove is arc-shaped, and the front two sides of the limiting rotation block are inclined.

[0009] Preferably, the inner sides of both ends of the silicone seat are inclined.

[0010] Preferably, the inner side of the module is provided with multiple mounting components, each mounting component consisting of mounting holes and screws. The mounting holes are opened on the inner side of the module, and the screws pass through the interior of the mounting holes.

[0011] Preferably, cooling water tanks are provided on the inner side of the plurality of modules, and cooling water holes are provided on the side of the modules.

[0020] 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.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a plastic extrusion mold with a cooling structure, comprising multiple modules 1, each module 1 having an orifice 2 of different sizes on its inner side, and a locking mechanism between the multiple modules 1. The locking mechanism increases the ease of assembly of the multiple modules 1. The locking mechanism consists of symmetrically arranged limiting components 11 and symmetrically arranged fixing components 12. The limiting components 11 consist of a limiting rotation groove 111, a limiting rotation block 112, and a silicone seat 113. The limiting rotation groove 111 is formed in the module 1. On the top surface, the insertion range of the limiting rotating block 112 is expanded by the limiting rotating groove 111, increasing the convenience of aligning multiple modules 1 with the mounting holes 31 through the limiting component 11. The limiting rotating block 112 is fixed to the bottom end of the module 1, and the silicone seat 113 is fixed to the inner side of the end of the limiting rotating groove 111. The fixing component 12 consists of a fixing block 121 and a fixing groove 122. The fixing block 121 is fixed to the bottom edge of the module 1, and the fixing groove 122 is opened at the top edge of the module 1. The fixing block 121 is inserted into the inner side of the fixing groove 122. On the other hand, the designed locking mechanism improves the problem of obstruction between the mounting holes 31 during the alignment of multiple modules 1 when they need to be assembled, which affects the assembly efficiency. By setting a locking mechanism between multiple modules 1, the mounting holes 31 are aligned through the locking mechanism during the assembly process, thereby increasing the ease of assembly. The four corners of the fixing block 121 are inclined, and the two sides of the fixing groove 122 are inclined. The width of the fixing groove 122 is greater than the width of the fixing block 121. The outer surface of the fixing block 121 is at the same level as the side of the module 1. The cross-section of the limiting rotation groove 111 is arc-shaped. The front ends of the limiting rotation block 112 are inclined. The inner sides of both ends of the silicone seat 113 are inclined. Multiple mounting components 3 are provided on the inner side of the module 1. The mounting components 3 consist of mounting holes 31 and screws 32. The mounting holes 31 are opened on the inner side of the module 1, and the screws 32 pass through the interior of the mounting holes 31.

[0022] In this embodiment, preferably, cooling water tanks are provided on the inner side of multiple modules 1, and cooling water holes 4 are provided on the side of modules 1. When the plastic extrusion mold is in operation, cooling water is connected to the outside through the cooling water holes 4, so that the cooling water flows inside the cooling water tank to cool the plastic extrusion mold.

[0023] The working principle and usage process of this utility model are as follows: During the use of the plastic extrusion die, it is installed on the extruder. First, the powdered or granular polymer is added to the extruder barrel. Under the action of the screw or plunger, the polymer moves forward along the screw channel or barrel and gradually melts into a viscous fluid. Then, this molten plastic passes through the plastic extrusion die set at the end of the barrel to form a continuous body with a shape similar to the die orifice 2 of the plastic extrusion die. Finally, after cooling and solidification, it can be formed into the desired shape.

[0024] When multiple modules 1 of a plastic extrusion mold need to be assembled, a limiting rotating block 112 symmetrically fixed at the bottom of one module 1 is inserted into the limiting rotating groove 111 on the surface of another module 1. Then, one of the modules 1 is rotated, causing the limiting rotating block 112 to rotate inside the limiting rotating groove 111. When the limiting rotating block 112 rotates to the end of the limiting rotating groove 111 and is fixed by the silicone seat 113, the fixing block 121 is inserted into the inside of the fixing groove 122. At this time, the multiple mounting holes 31 are aligned, and then the screw 32 is inserted to complete the assembly of the module 1.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
