Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically relating to an injection mold that is easy to dissipate heat. Background Technology

[0002] Injection molds are key tools for producing plastic products, giving them a complete structure and precise dimensions. Injection molding is a process for mass-producing complex parts, in which molten plastic is injected into the mold cavity under high pressure by an injection molding machine, and the molded product is obtained after cooling and solidification.

[0003] Injection molds require a cooling system to lower their temperature. A common method is to create cooling water channels inside the mold, relying on circulating water to carry the heat. However, after long-term use, scale easily accumulates on the inner walls of the water channels, reducing heat dissipation efficiency. Therefore, regular acid cleaning is necessary. Before cleaning, the mold needs to be disassembled and transported to a designated location. Due to the mold's considerable weight, the transportation process is very inconvenient, making the entire acid cleaning process cumbersome and ultimately affecting the efficiency of the cooling water channel acid cleaning work. Utility Model Content

[0004] The purpose of this utility model is to provide an injection mold that is easy to dissipate heat. When cleaning the mold, there is no need to disassemble the mold. Only the copper heat dissipation pipe and the U-shaped assembly pipe need to be removed and then transported to the designated location for cleaning. There is no need to move the mold. The operation is simple and convenient, which improves the work efficiency of the staff.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An injection mold that facilitates heat dissipation, including

[0007] Both the lower and upper molds have two through holes distributed front and back on both the left and right sides.

[0008] There are two heat dissipation mechanisms, which are installed inside two through holes on the upper and lower sides respectively;

[0009] The heat dissipation mechanism includes two copper heat dissipation pipes and a U-shaped assembly pipe. The two copper heat dissipation pipes are respectively inserted into two through holes. The left end of the copper heat dissipation pipes is fixedly connected to a conveying pipe. The middle left side of the conveying pipe is fixedly connected to a first assembly head. The right end of both copper heat dissipation pipes is equipped with a plug-in connector. Both ends of the U-shaped assembly pipe are equipped with socket joints that connect to the plug-in connectors. The middle right side of the U-shaped assembly pipe is fixedly connected to a second assembly head.

[0010] There are four fixing mechanisms, which are respectively installed on the left and right sides of the lower mold and the upper mold.

[0011] As a preferred technical solution, the plug-in connector includes a mounting head, which is fixedly installed on the end of the copper heat sink tube. Several first sealing rings are evenly installed around the periphery of the mounting head, and a second sealing ring that abuts against the end of the mounting head is fixedly installed inside the socket joint.

[0012] As a preferred technical solution, the fixing mechanism includes a U-shaped assembly plate, with an abutment groove on the front side of the U-shaped assembly plate, and openings on the U-shaped assembly plate that match the positions of the first assembly head and the second assembly head. Two assembly plates are fixedly installed on both the front and rear sides of the U-shaped assembly plate, and all four assembly plates have threaded holes. Four threaded connection holes are opened on the left and right sides of both the lower mold and the upper mold.

[0013] As a preferred technical solution, assembly blocks are fixedly installed on both the left and right sides of the mold and the upper mold. Placement slots are opened on the side of the four assembly blocks that are far apart from each other. Two conveying pipes and two U-shaped assembly pipes are located inside the four placement slots respectively. Installation slots are opened on the inner walls of the two placement slots on the upper and lower sides that are close to each other.

[0014] The fixing mechanism includes a triangular block, which is slidably assembled inside the mounting groove. A spring is fixedly installed on one side of the triangular block, and the end of the spring is fixedly connected to the inner wall of the mounting groove. A sliding groove communicating with the mounting groove is opened on the front side of the assembly block, and a toggle block that is slidably connected to the sliding groove is fixedly installed on the front side of the triangular block.

[0015] The beneficial effects of this utility model are:

[0016] 1. Excellent heat dissipation and reliable sealing: The copper heat dissipation pipe is in direct contact with the inner wall of the mold through hole, resulting in high heat conduction efficiency. Combined with water circulation, it can quickly cool down. At the same time, the gap sealing of the first sealing ring and the end sealing of the second sealing ring form a multi-layer sealing structure, which can effectively prevent coolant leakage and does not affect normal transportation.

[0017] 2. Easy to assemble and disassemble and reduce labor intensity: During installation, only the pipe body needs to be inserted and the U-shaped assembly plate needs to be fixed, without the need for complicated tools; during disassembly and cleaning, there is no need to carry heavy molds, only the heat dissipation pipe needs to be pulled out, which greatly reduces the number of operating steps and physical exertion of the staff.

Detailed Implementation

[0027] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1:

[0029] like Figure 1-5 As shown, this utility model provides an injection mold with easy heat dissipation, comprising:

[0030] The lower mold 1 and the upper mold 2 each have two through holes 3 distributed front and back on both the left and right sides;

[0031] There are two heat dissipation mechanisms 4, which are respectively installed inside the two through holes 3 on the upper and lower sides.

[0032] The heat dissipation mechanism 4 includes two copper heat dissipation pipes 41 and a U-shaped assembly pipe 44. The two copper heat dissipation pipes 41 are respectively inserted into two through holes 3. The left end of the copper heat dissipation pipes 41 is fixedly connected to a conveying pipe 42. The middle left side of the conveying pipe 42 is fixedly connected to a first assembly head 43. The right end of each of the two copper heat dissipation pipes 41 is equipped with a plug-in connector. Both ends of the U-shaped assembly pipe 44 are equipped with socket joints 45 that are connected to the plug-in connectors. The middle right side of the U-shaped assembly pipe 44 is fixedly connected to a second assembly head 451.

[0033] There are four fixing mechanisms 5, which are respectively installed on the left and right sides of the lower mold 1 and the upper mold 2.

[0034] In use, taking one of the heat dissipation mechanisms 4 as an example, in the initial state, when the heat dissipation mechanism needs to be installed, two copper heat dissipation pipes 41 are inserted into the inner walls of two through holes 3 and tightly abut against the inner walls. After the two copper heat dissipation pipes 41 drive the two plug-in connectors to extend out of the through holes 3, the two socket joints 45 are used to plug and fix the two plug-in connectors and complete the sealing after plugging. After installation, the four fixing mechanisms 5 are used to fix the positions of the two delivery pipes 42 and the two U-shaped assembly pipes 44 respectively. The two first assembly heads 43 and the second assembly heads 451 on the left and right sides are connected and fixed to the external liquid delivery head and liquid discharge head, so that water circulation can be realized. When the mold is injected, the copper heat dissipation pipes 41 are used to effectively cool the lower mold 1 and the upper mold 2.

[0035] When it is necessary to disassemble and clean after a period of use, there is no need to disassemble the mold. After contacting the fixing mechanism 5, pull out the connection between the four plug-in connectors and the four socket connectors 45, then pull out the four copper heat dissipation pipes 41 and take them to the designated cleaning position for cleaning. The operation is simple and convenient, and there is no need to move the mold, which reduces the labor intensity of the staff.

[0036] The plug-in connector includes a mounting head 6, which is fixedly mounted on the end of the copper heat sink 41. Several first sealing rings 62 are evenly mounted around the periphery of the mounting head 6. A second sealing ring that abuts against the end of the mounting head 6 is fixedly mounted inside the socket joint 45.

[0037] During insertion, after the mounting head 6 is inserted into the socket joint 45, several sealing rings 62 undergo elastic deformation under pressure, which can seal the gap between the mounting head 6 and the socket joint 45. The second sealing ring tightly abuts against the end of the mounting head 6 for sealing. This multi-layer sealing improves the sealing effect and prevents leakage without affecting the coolant delivery. The insertion operation is simple and convenient.

[0038] The fixing mechanism 5 includes a U-shaped assembly plate 51. The front side of the U-shaped assembly plate 51 is provided with an abutment groove 52. The U-shaped assembly plate 51 has an opening 53 that matches the position of the first assembly head 43 and the second assembly head 451. Two assembly plates 54 are fixedly installed on both the front and rear sides of the U-shaped assembly plate 51. All four assembly plates 54 have threaded holes 55. The lower mold 1 and the upper mold 2 are provided with four threaded connection holes on the left and right sides.

[0039] After the two conveying pipes 42 and the two U-shaped assembly pipes 44 are assembled, taking one of the U-shaped assembly plates 51 as an example, the abutting groove 52 opened in the U-shaped assembly plate 51 is used to abut the conveying pipe 42 or the U-shaped assembly pipe 44. The inner wall of the abutting groove 52 abuts against the conveying pipe 42 or the U-shaped assembly pipe 44, which can prevent the conveying pipe 42 or the U-shaped assembly pipe 44 from shifting. The opening 53 is aligned with the first assembly head 43 and the second assembly head 451 to avoid blocking the first assembly head 43 and the second assembly head 451. Then, the four assembly plates 54 can be fixedly connected to the lower mold 1 or the upper mold 2 using screws.

[0040] Example 2:

[0041] Further improvements were made based on Example 1, such as... Figure 6-7 As described above, assembly blocks 7 are fixedly installed on the left and right sides of the lower mold 1 and the upper mold 2. Placement slots 71 are opened on the side of the four assembly blocks 7 that are far apart from each other. Two conveying pipes 42 and two U-shaped assembly pipes 44 are respectively located inside the four placement slots 71. Installation slots 72 are opened on the inner wall of the two placement slots 71 on the upper and lower sides that are close to each other.

[0042] The fixing mechanism 5 includes a triangular block 73, which is slidably assembled inside the mounting groove 72. A spring 74 is fixedly installed on one side of the triangular block 73, and the end of the spring 74 is fixedly connected to the inner wall of the mounting groove 72. A sliding groove 75 communicating with the mounting groove 72 is opened on the front side of the assembly block 7, and an actuating block 76 slidably connected to the sliding groove 75 is fixedly installed on the front side of the triangular block 73.

[0043] The inclined surface of the triangular block 73 corresponds to the side of the two conveying pipes 42 and the two U-shaped assembly pipes 44 closest to the upper mold 1 and the lower mold 2. When the two conveying pipes 42 and the two U-shaped assembly pipes 44 are inserted and assembled, taking one set as an example, in the initial state, the spring 74 pushes one end of the triangular block 73 out of the mounting groove 72. When the two conveying pipes 42 and the two U-shaped assembly pipes 44 are assembled, the two conveying pipes 42 and the two U-shaped assembly pipes 44 abut against the inclined surface of the triangular block 73, which can push the triangular block 73 into the slide groove 75. After assembly, the vertical surface of the triangular block 73 will abut against the periphery of the conveying pipe 42 or the U-shaped assembly pipe 44 to prevent its reverse displacement. Such assembly and placement do not require additional fixing, further improving the work efficiency of the workers. When disassembling, first contact the limit of the triangular block 73, that is, drive the toggle block 76 to move, and drive the triangular block 73 into the slide groove 75. The operation is simple and convenient.

[0044] The device is used as follows:

[0045] When using this easy-to-dissipate injection mold, in the initial state, if it is necessary to install the heat dissipation mechanism 4, taking one of the heat dissipation mechanisms 4 as an example, first insert the two copper heat dissipation pipes 41 into the two through holes 3 on the corresponding side of the lower mold 1 or the upper mold 2, and ensure that the copper heat dissipation pipes 41 are tightly abutted against the inner wall of the through hole 3; after the two copper heat dissipation pipes 41 drive the plug-in connectors at the ends to extend out of the through hole 3, align the socket joints 45 at both ends of the U-shaped assembly pipe 44 with the two plug-in connectors and insert them, so that the mounting head 6 is inserted into the socket joint 45, and the sealing is completed by the elastic deformation of the first sealing ring 62 and the abutment of the second sealing ring with the end of the mounting head 6.

[0046] After the heat dissipation mechanism 4 is assembled, the delivery pipe 42 and the U-shaped assembly pipe 44 are fixed by the fixing mechanism 5.

[0047] Finally, connect the first assembly head 43 on both sides to the external liquid inlet and the second assembly head 451 to the external liquid outlet to allow coolant to flow and achieve water circulation. During the mold injection process, the copper heat dissipation pipe 41 can directly absorb the heat from the lower mold 1 and the upper mold 2 and carry away the heat through the coolant to achieve cooling.

[0048] If the heat dissipation mechanism 4 needs to be removed for cleaning after a period of use, after removing the fixing mechanism 5, pull out the connection between the plug-in connector and the socket connector 45, and pull the four copper heat dissipation pipes 41 out of the through hole 3. Then it can be carried to the designated location for cleaning without disassembling the entire mold.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
