Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a water-cooling structure for injection molds. Background Technology

[0002] As is well known, injection molds are typically equipped with water cooling systems to cool or heat the mold, ensuring that the mold temperature meets the requirements of specific injection molding materials or molding processes. These water cooling systems accelerate the production cycle, maintain product quality, and extend the mold's lifespan. During injection molding, the male and female mold cores must assemble and fit with the mold blank. Because the male and female mold cores require high precision, smaller dimensions facilitate high-precision core machining and direct manufacturing, which helps ensure the dimensional accuracy and consistency of the injection molded product, resulting in a thinner mold plate.

[0003] However, the inventors discovered that when assembling the water supply connector, both the screw holes on the mold plate and the water supply connector are 1 / 4 thread. The mold plate, having undergone heat treatment, has a relatively fragile structure. The thickness between the mold plate and the screw holes is thin, and during repeated use and disassembly of the mold, whether subjected to the opening and closing pressure of the injection molding machine or during tightening, the weak points of the mold plate and screw holes are prone to cracking, causing damage to the mold plate. This greatly increases production costs, affects production efficiency, and reduces the service life of the mold plate. Utility Model Content

The transfer plate is provided with a water inlet transfer hole connected to the water inlet and a water outlet transfer interface connected to the water outlet.

[0006] Furthermore, the side wall of the mold plate is provided with a positioning groove, the inner contour of which matches the outer contour of the adapter plate, so that the adapter plate is placed in the positioning groove, and the positioning groove is provided with the water inlet and the water outlet.

[0007] Furthermore, the positioning groove is a rectangular positioning groove, and a first positioning structure is provided at the four corners of the rectangular positioning groove. The adapter plate is provided with a second positioning structure corresponding to the first positioning structure.

[0008] Furthermore, the mold plate is provided with a first threaded hole, and the adapter plate is provided with a second threaded hole corresponding to the first threaded hole, so that the mold plate and the adapter plate can be detachably locked and fixed by screws.

[0010] Furthermore, the sealing structure includes an annular groove and a waterproof ring, wherein the waterproof ring is disposed in the annular groove.

[0011] Furthermore, the thickness of the waterproof ring is greater than the depth of the annular groove.

[0012] Furthermore, it also includes a first water-carrying connector and a second water-carrying connector, the first water-carrying connector being connected to the water inlet adapter hole, and the second water-carrying connector being connected to the water outlet adapter hole.

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figures 1 to 4 A water-cooling structure for an injection mold includes a mold blank plate 1 and a transition plate 2. The mold blank plate 1 is provided with a water inlet 11, a water outlet 12 and a water channel 13. The water channel 13 is connected to the water inlet 11 and the water outlet 12 respectively. The transition plate 2 is connected to the mold blank plate 1. The transition plate 2 is provided with a water inlet transition hole 21 connected to the water inlet 11 and a water outlet transition interface 22 connected to the water outlet 12.

[0027] As can be seen from the above description, the beneficial effects of this utility model are as follows: The water-cooling structure of the injection mold provided by this utility model connects the mold blank plate 1 to the external water cooling device by setting the adapter plate 2, so that the thin mold blank plate 1 does not need to be drilled and tapped, avoiding the mold blank plate 1 from cracking due to the installation of the water-cooling connector. At the same time, the manufacturing cost of the adapter plate 2 is relatively low. The water-cooling structure of the injection mold provided by this utility model can reduce production costs, effectively extend the service life of the mold, and reduce safety hazards.

[0028] Furthermore, the side wall of the mold plate 1 is provided with a positioning groove 14, the inner contour of the positioning groove 14 matches the outer contour of the adapter plate 2, so that the adapter plate 2 is disposed in the positioning groove 14, and the positioning groove 14 is provided with the water inlet 11 and the water outlet 12.

[0029] As described above, the adapter plate 2 is installed in the positioning groove 14. On the one hand, this facilitates the installation of the mold base plate 1 and the adapter plate 2, reducing the risk of mold base plate 1 breaking due to incorrect installation. On the other hand, it ensures the effective positioning of the adapter plate 2 and the mold base plate 1, preventing the adapter plate 2 from falling off during injection molding and causing production accidents, and improving the reliability of the water channel 13 function in the mold base plate 1.

[0030] Furthermore, the positioning groove 14 is a rectangular positioning groove 14, and a first positioning structure is provided at the four corners of the rectangular positioning groove 14. The adapter plate 2 is provided with a second positioning structure corresponding to the first positioning structure.

[0031] As can be seen from the above description, the positioning and installation effect of the adapter plate 2 and the mold blank plate 1 is good, so the water conveying mechanism of the injection mold is highly reliable.

[0032] Furthermore, the mold plate 1 is provided with a first threaded hole 15, and the adapter plate 2 is provided with a second threaded hole 23 corresponding to the first threaded hole 15, so that the mold plate 1 and the adapter plate 2 can be detachably locked and fixed by screws.

[0033] As described above, when the adapter plate 2 is connected to the mold plate 1, it needs to be fixed first. The first threaded hole 15 is set in the square groove of the adapter plate 2 and the mold plate 1 in a position that does not affect the water inlet hole. The size of the first threaded hole 15 for installing bolts is small, so the structure of the first threaded hole 15 is not likely to cause the mold plate 1 to crack or be damaged. When waiting to be installed, the adapter plate 2 is fixed in the template with fixing screws to prevent accidents such as the adapter plate 2 falling off during use.

[0034] Furthermore, the mold plate 1 is provided with a sealing structure 16, which is provided corresponding to the water inlet 11 and / or the water outlet 12.

[0035] As can be seen from the above description, the sealing structure 16 can ensure the sealing of the water inlet channel formed by the connection between the water inlet adapter hole 21 and the water inlet 11.

[0036] Furthermore, the sealing structure 16 includes an annular groove 161 and a waterproof ring 162, wherein the waterproof ring 162 is disposed in the annular groove 161.

[0037] As can be seen from the above description, the waterproof ring 162 can ensure the sealing of the water inlet channel formed by the connection between the water inlet adapter hole 21 and the water inlet 11.

[0038] Furthermore, the thickness of the waterproof ring 162 is greater than the groove depth of the annular groove 161.

[0039] As can be seen from the above description, when the adapter plate 2 and the mold plate 1 are locked together by screws, the waterproof ring 162 can provide excellent sealing at the connection between the water inlet 11 and the adapter water inlet.

[0040] Furthermore, it also includes a first water-carrying connector 3 and a second water-carrying connector 4, the first water-carrying connector 3 being connected to the water inlet adapter hole 21, and the second water-carrying connector 4 being connected to the water outlet adapter hole.

[0041] As can be seen from the above description, the first water connector 3 and the second water connector 4 are used to connect to the water inlet and water outlet of the water cooling device.

[0042] Furthermore, the first water connector 3 is threadedly connected to the water inlet adapter hole 21, and the second water connector 4 is threadedly connected to the water outlet adapter hole 22.

[0043] As described above, the water-cooling structure of this injection mold eliminates the need for threaded holes on the mold base plate 1 to connect the first water-cooling connector 3 and the second water-cooling connector 4, preventing cracking or damage to the mold base plate 1 during the connection and installation process with the water-cooling connectors. This water-cooling structure of the injection mold can improve the service life of the mold. The adapter plate 2 has threaded holes that match the water-cooling connectors. The adapter plate 2 has a simple structure and low manufacturing cost. Even if the adapter plate 2 is damaged, it can be quickly replaced or repaired. This injection mold structure can improve production efficiency and reduce manufacturing costs.

[0044] Furthermore, the mold plate 1 is provided with a plurality of water channels 13, and the plurality of water channels 13 are all connected to the water inlet 11 and the water outlet 12.

[0045] As can be seen from the above description, the water channel structure of the injection mold can ensure the temperature control effect of the mold blank plate 1 during the injection process, and ensure the smooth flow of cooling water in the mold blank plate 1.

[0046] Example 1

The transition plate 2 is connected to the mold blank plate 1. The transition plate 2 is provided with a water inlet transition hole 21 connected to the water inlet 11 and a water outlet transition interface 22 connected to the water outlet 12.

The inner contour of the positioning groove 14 matches the outer contour of the adapter plate 2 so that the adapter plate 2 is placed in the positioning groove 14. The positioning groove 14 is provided with an inlet 11 and an outlet 12.

[0049] Of course, as an option, the mold plate 1 may not have the positioning groove 14 structure. Instead, the water inlet 11 and the water outlet 12 can be connected to the water inlet transition hole 21 and the water outlet transition hole 22 respectively by the side wall of the mold plate 1 abutting against the adapter plate 2.

[0050] In this embodiment, the positioning groove 14 can be specifically set as a rectangular positioning groove 14, and a first positioning structure is provided at each of the four corners of the rectangular positioning groove 14.

[0051] Optionally, the first positioning structure can be a first threaded hole 15 on the mold plate 1, and the second positioning structure can be a second threaded hole 23 on the adapter plate 2 corresponding to the first threaded hole 15, so that the mold plate 1 and the adapter plate 2 can be detachably locked and fixed by screws, thereby achieving positioning and fixed connection between the mold plate 1 and the adapter plate 2 through the first positioning structure and the second positioning structure. The locking and fixing of the mold plate 1 and the adapter plate 2 by screws can ensure the positioning and installation effect of the mold plate 1 and the adapter plate 2, and ensure the sealing of the water inlet channel formed by the connection between the water inlet adapter hole 21 and the water inlet 11.

[0052] Of course, in other embodiments of this utility model, the first positioning structure and the second positioning structure can be replaced by other structures with positioning functions. For example, the first positioning structure can be a positioning pin provided on the mold plate 1, and the second positioning structure can be a positioning hole or positioning groove 14 provided with the corresponding positioning pin. This utility model does not limit the specific setting method of the first positioning structure and the second positioning structure.

[0053] To ensure the airtight connection between the water inlet 11 and the water inlet adapter hole 21, and between the water outlet 12 and the water outlet adapter hole 22, a sealing structure 16 is provided on the mold plate 1, and the sealing structure 16 is provided corresponding to the water inlet 11 and / or the water outlet 12.

[0054] Please refer to Figure 3 In this embodiment, the sealing structure 16 includes an annular groove 161 and a waterproof ring 162, with the waterproof ring 162 disposed in the annular groove 161. Preferably, the thickness of the waterproof ring 162 is greater than the groove depth of the annular groove 161, so that when the adapter plate 2 and the mold plate 1 are locked together with screws, the waterproof ring 162 can provide an excellent seal at the connection between the water inlet 11 and the adapter water inlet hole.

[0055] Combination Figures 1 to 4 For reference, the water-cooling structure of the injection mold also includes a first water-cooling connector 3 and a second water-cooling connector 4. The first water-cooling connector 3 is connected to the water inlet adapter hole 21, and the second water-cooling connector 4 is connected to the water outlet adapter hole. The first water-cooling connector 3 is threadedly connected to the water inlet adapter hole 21, and the second water-cooling connector 4 is threadedly connected to the water outlet adapter hole 22.

[0056] In detail, the water inlet adapter hole 21 and the water outlet adapter hole have the same structure. Both are stepped holes. Both the water inlet adapter hole 21 and the water outlet adapter hole include a first hole section and a second hole section. The diameter of the first hole section is larger than the diameter of the second hole section. The first hole section is connected to the first / second water connector 4, and the second hole section is connected to the inlet / outlet 12.

[0057] Reference Figure 2 As can be seen, the mold plate 1 is provided with multiple water channels 13, and the multiple water channels 13 are connected to the water inlet 11 and the water outlet 12. The multiple water channels 13 in the mold plate 1 are interconnected, which can ensure that the cooling water in the mold plate 1 flows smoothly in the water channels 13.

[0058] In summary, the water-cooling structure for injection molds provided by this utility model connects the mold blank 1 to the external water cooling device by setting the adapter plate 2, so that the thin mold blank 1 does not need to be drilled or tapped, avoiding the mold blank 1 from cracking due to the installation of water-cooling connectors.
