[0022] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0023] A mold insert structure that is easy to dissipate heat according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a mold insert structure that is easy to dissipate heat, including an insert 1, an exhaust component is arranged inside the insert 1; the exhaust component includes a plurality of air holes 3, a movable groove 4, a screw 5, an exhaust member 6 and a plurality of through holes 8, the movable groove 4 and the plurality of air holes 3 are opened at one end of the insert 1, the screw 5 is installed on the groove wall of the movable groove 4, the exhaust member 6 is rotatably installed at one end of the screw 5, and a plurality of through holes 8 are opened at the bottom end of the exhaust member 6.

[0026] It should be noted that by setting up the exhaust component, when the injection molded product needs to be vented and heat dissipated, the air duct inside the insert 1 can be connected by turning the screw 5, which facilitates exhaust and heat dissipation and improves the heat dissipation performance of the insert 1. By setting up the screw 5, the exhaust part 6 and the sealing rod 7 can be moved more easily, and the exhaust part 6 is used to connect the air hole 3.

[0027] In some embodiments, Figure 2 , Figure 3 As shown, a sealing rod 7 is fixedly installed at the bottom end of the exhaust member 6, through holes 8 are located on both sides of the sealing rod 7, the other end of the through hole 8 extends to the outer wall of the exhaust member 6, and one end of the air hole 3 is connected to the movable groove 4.

[0028] It should be noted that the insert 1 is installed on the mold core. When the injection molded product inside needs to be vented and dissipated, the screw 5 is turned to drive the screw 5 to move upward in the movable groove 4, and at the same time drive the exhaust member 6 to move upward, so that the through hole 8 on the outer wall of the exhaust member 6 is connected with the air hole 3 on the groove wall of the movable groove 4. At this time, the sealing rod 7 moves upward and disengages from the seal of the blocking ring 9, so that the internal gas can be discharged to the through hole 8 and discharged through the air hole 3.

[0029] In this example, one end of the through hole 8 located on the outer wall of the exhaust member 6 is larger to facilitate connection with the air hole 3 .

[0030] In some embodiments, Figure 3 As shown, a thread is provided at the top of the groove wall of the movable groove 4, a screw rod 5 is movably installed at the thread of the groove wall of the movable groove 4, a blocking ring 9 is fixedly installed at the bottom end of the groove wall of the movable groove 4, a sealing rod 7 is engaged with the inner wall of the blocking ring 9, a fixing part 2 is fixedly installed on the outer wall of the insert 1, and a plurality of threaded holes are provided on the fixing part 2.

[0031] It should be noted that, by providing the thread and the screw 5, the exhaust member 6 and the sealing rod 7 can be moved more easily, and more exhaust components can be provided on the inner wall of the insert 1 to accelerate the exhaust.

[0032] Example 2

[0033] In some embodiments, Figure 4As shown, a slide groove 10 is provided at the top of the screw rod 5 , a movable plate 11 is slidably mounted on the groove wall of the slide groove 10 , and a shift plate 12 is fixedly mounted on the top of the movable plate 11 .

[0034] It should be noted that the slide groove 10 and the movable plate 11 are both cross-shaped. By providing a movable movable plate 11 and a dial plate 12, when installing the insert 1, the dial plate 12 can be retracted into the slide groove 10 without affecting the installation of the insert 1. When it is necessary to screw the screw 5, the dial plate 12 is pulled out to facilitate the rotation of the screw 5.

[0035] In this example, the slide groove 10 serves to accommodate the movable plate 11, and the movable plate 11 in the slide groove 10 can drive the screw 5 to rotate when the paddle 12 is turned through the slide groove 10 through the cross-shaped groove design. When the insert structure is installed on the mold core, one end of the movable plate 11 and the paddle 12 are installed to extend to the outside of the mold core. When the staff pulls the movable plate 11 out of the slide groove 10, the paddle 12 is exposed at one end of the screw 5, and the staff can turn the paddle 12 by hand to drive the screw 5 to rotate.

[0036] Working principle: When the internal injection molded product needs to be vented and heat dissipated, screw 5 is turned to drive screw 5 to move upward in movable groove 4, and at the same time drive exhaust member 6 to move upward, so that through hole 8 on the outer wall of exhaust member 6 is connected with air hole 3 on the groove wall of movable groove 4. At this time, sealing rod 7 moves upward, disengaging from the seal of blocking ring 9, so that the internal gas can be discharged to through hole 8 and discharged through air hole 3.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
