[0031] Referring to Figure 1 as shown, the present utility model provides a technical solution: an injection mold with a heat dissipation function, including a mold body 1, a heat dissipation structure 2 is provided on the surface of the mold body 1, and an auxiliary structure 3 is provided on the surface of the heat dissipation plate 21.

[0032] The following specifically describes the specific settings and functions of its mold body 1 and auxiliary structure 3.

[0033] Referring to Figures 1-5 as shown, in this embodiment: the heat dissipation structure 2 includes a heat dissipation plate 21 and a plurality of positioning holes 24 that are evenly arranged on the mold body 1 in pairs. A plurality of heat dissipation strips 28 are detachably installed on the surface of the heat dissipation plate 21. The heat dissipation strips 28 are of a double-layer structure. Two positioning pins 25 are fixedly connected to the surface of the heat dissipation plate 21. The size of the positioning pins 25 is adapted to the size of the positioning holes 24. When installing the heat dissipation plate 21 on the mold body 1, align the positioning pins 25 and insert them into the inside of the positioning holes 24. At this time, the preliminary positioning and installation work of the heat dissipation plate 21 can be realized.

[0034] The side wall of the mold body 1 is fixedly connected with a number of rectangular blocks 22 in groups of two, and a card frame 23 is slidably connected inside the rectangular block 22, and a slope structure is provided on the end side of the card frame 23. In the process of pressing the heat sink 21, the heat sink 21 will move relative to the slope of the card frame 23, and the card frame 23 can be pushed and opened at this time. A spring 27 is fixedly connected between the card frame 23 and the rectangular block 22. The card frame 23 will be pulled by the spring 27 and sleeved on the surface of the heat sink 21, and the locking installation of the heat sink 21 can be achieved at this time. The end side of the locating pin 25 is fixedly connected with an auxiliary head 26 of a truncated cone structure. Among them, the auxiliary head 26 of the truncated cone structure improves the efficiency of the locating pin 25 inserted into the inner side of the locating hole 24.

[0035] Reference Figures 3-7 As shown, specifically, the auxiliary structure 3 includes a plurality of trapezoidal grooves 33 provided on the side wall of the heat sink 21, and the heat sink 28 is slidably connected to the inner side of the trapezoidal grooves 33. When it is necessary to clean or maintain the heat sink 28 individually, the heat sink 28 located on the inner side of the trapezoidal grooves 33 can be pulled out, and the individual heat sink 28 can be cleaned individually. The side wall of the heat sink 21 is fixedly connected with a connecting pin 32, and the side wall of the connecting pin 32 is rotatably connected with a baffle 31. After installing the rows of heat sinks 28, the baffle 31 on the connecting pin 32 can be rotated to achieve simultaneous limiting and shielding of multiple heat sinks 28. The side wall of the heat sink 21 is fixedly connected with a limiting block 34, and the cross section of the limiting block 34 is an L-shaped structure. The baffle 31 is turned into the inner side of the limiting block 34 to achieve the installation of the heat sink 28.

[0036] Working principle: when the heat sink 21 on the mold body 1 needs to be installed, the positioning pin 25 is aligned and inserted into the inner side of the positioning hole 24, wherein the auxiliary head 26 with a truncated cone structure improves the efficiency of inserting the positioning pin 25 into the inner side of the positioning hole 24, and the preliminary positioning and installation of the heat sink 21 can be achieved at this time. In the process of pressing the heat sink 21, the heat sink 21 will move relative to the inclined surface of the card frame 23, and the pushing and opening work of the card frame 23 can be achieved at this time. When the heat sink 21 moves to a position close to the surface of the mold body 1, the card frame 23 will be pulled by the spring 27 and sleeved on the surface of the heat sink 21, and the heat sink 21 can be achieved at this time. The lock installation work of the heat sink 21 is now carried out. By setting the heat sink 21 and the mold body 1 in a detachable manner, the regular maintenance of the heat sink 21 is facilitated, and the performance of the heat sink 21 is further improved. The heat of the mold body 1 will be conducted through the heat sink 21 and the heat sink strip 28, which increases the heat dissipation area of ​​the mold body 1, thereby improving the performance of the mold body 1. By setting the heat dissipation structure 2 and the detachable heat sink 21, the flexible disassembly and assembly of the heat sink 21 on the mold body 1 is facilitated, which can accelerate the solidification time of the plastic product, shorten the injection molding cycle, and improve production efficiency.

[0037] When it is necessary to clean or maintain the heat sink 28 separately, the heat sink 28 located on the inner side of the trapezoidal groove 33 can be pulled out and the single heat sink 28 can be cleaned separately. When installing the heat sink 28 again, the heat sink 28 can be directly inserted into the inner side of the trapezoidal groove 33. After the heat sink 28 in a row is installed, the blocking bar 31 on the connecting pin 32 can be rotated to achieve the simultaneous limiting and shielding work of multiple heat sinks 28. The blocking bar 31 can be turned into the inner side of the limiting block 34 to achieve the installation of the heat sink 28. By setting the auxiliary structure 3, the flexible disassembly and assembly of the heat sink 28 is facilitated, and the separate removal and cleaning of the heat sink 28 is facilitated, thereby further improving the heat dissipation effect of the heat sink 28.
