[0039] This utility model provides a core-pulling mechanism, a moving mold, and an injection mold to improve the aesthetic appearance of products.

[0040] The following is combined Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0041] This utility model provides a core-pulling mechanism, including:

[0042] The main body of the mechanism 100 includes a slider insert 110 and a rocker arm 120. The slider insert 110 is disposed in a sliding groove 310 in the moving mold insert 300, and the slider insert 110 can slide along the sliding groove 310 between the core-pulling position and the forming position.

[0043] The middle part of the swing rod 120 is pivotally connected to the moving mold insert 300, and the first end of the swing rod 120 is connected to the slider insert 110;

[0044] A drive assembly 200 is connected to the second end of the rocker arm 120. The drive assembly 200 is used to drive the second end of the rocker arm 120 to reciprocate, so that the rocker arm 120 swings around the pivot center of the middle part of the rocker arm 120, thereby driving the slider insert 110 to reciprocate within the moving mold insert 300.

[0045] The core-pulling mechanism provided by this utility model includes a mechanism body 100 and a drive assembly 200. The mechanism body 100 includes a slider insert 110 and a rocker arm 120. The slider insert 110 is disposed in a sliding groove 310 within a moving mold insert 300, and the slider insert 110 can slide along the sliding groove 310 between the core-pulling position and the molding position. When the slider slides to the molding position, the product part can be injection molded. When the slider insert slides to the core-pulling position, the slider insert 110 disengages from the injection mold cavity. Since the slider is disposed within the moving mold insert 300, it can prevent the product from being molded... This addresses the issue of creasing, effectively improving the aesthetic appearance of the product. The swing arm 120 is pivotally connected to the moving mold insert 300 at its center. The first end of the swing arm 120 is connected to the slider insert 110, and the drive assembly 200 is connected to the second end of the swing arm 120. The drive assembly 200 can drive the slider insert 110 to slide within the sliding groove 310 via the swing arm 120, thus positioning it between the core-pulling position and the molding position. This leverage principle enables efficient and stable core-pulling action, improving the production efficiency and product quality of the injection mold.

[0046] In some embodiments of this utility model, the swing rod 120 is a columnar structure with a central bulge and tapered ends;

[0047] The swing rod 120 is disposed in the swing chamber 320 within the moving mold insert 300. The swing chamber 320 is connected to the sliding groove 310. The diameter of the middle part of the swing rod 120 is adapted to the inner diameter of the swing chamber 320.

[0048] In some embodiments of this utility model described above, the swing rod 120 is a cylindrical structure with a bulge in the middle and tapered ends. The swing rod 120 is disposed within the swing chamber 320 of the moving mold insert 300. The diameter of the middle part of the swing rod 120 is adapted to the inner diameter of the swing chamber 320, so that the swing rod 120 can swing back and forth around the middle part of the swing rod 120 as the swing center within the swing chamber 320 to complete the core pulling action. Since the swing rod 120 is disposed within the moving mold insert 300 and can be connected to the slider insert 110 for transmission, the space occupied by the core pulling mechanism can be reduced, the core pulling mechanism can be rationally set up, the moving mold structure can be simplified, the size can be reduced, and the space utilization rate can be improved.

[0049] It should be noted that the swing rod 120 is a cylindrical structure with a central drum and thinner ends. The swing rod 120 can swing by its own structure, which greatly simplifies the swing structure, makes the structure simpler, and ensures reliable operation so as to efficiently complete the core pulling action.

[0050] It is understood that the rocker arm 120 can also be located outside the moving mold insert 300, and the rocker arm 120 can be swung by the swing shaft to ensure that the slider insert 110 can slide stably between the core-pulling position and the molding position to complete the core-pulling action.

[0051] In some embodiments of this utility model, the drive assembly 200 includes a drive structure and a transmission component. The transmission component is provided with a positioning hole 220. The second end of the swing rod 120 is disposed in the positioning hole 220. The drive structure is connected to the transmission component and is used to drive the transmission component to reciprocate.

[0052] In some of the embodiments of the present invention described above, the driving assembly 200 includes a driving structure and a transmission component. The second end of the rocker arm 120 is disposed in the positioning hole 220 on the transmission component. When the transmission component moves under the drive of the driving structure, it can drive the second end of the rocker arm 120 to move, thereby causing the slider insert 110 to slide along the sliding groove 310, so that the slider insert 110 is in the core-pulling position and the forming position.

[0053] In some embodiments of this utility model, the main body 100 of the mechanism is provided with multiple sets, the transmission component is provided with multiple sets of positioning holes 220, and the second ends of multiple sets of swing rods 120 are disposed in the positioning holes 220.

The transmission structure is simple and the core pulling mechanism is optimized.

[0055] In some embodiments of this utility model, the driving structure includes a driving cylinder 250 and a driving push plate 230, the driving cylinder 250 is connected to the driving push plate 230, and the transmission component is detachably connected to the driving push plate 230.

[0057] In some embodiments of this utility model, the transmission component includes at least one set of transmission rods 210, the positioning hole 220 is disposed on the transmission rods 210, and at least one set of transmission rods 210 is connected to the drive push plate 230.

[0058] In some embodiments of the present invention described above, the transmission component includes at least one set of transmission rods 210, with positioning holes 220 provided on the transmission rods 210. The drive push plate 230 is connected to the transmission rods 210, thereby enabling a single drive cylinder 250 to drive at least one set of transmission rods 210 to move, completing the transmission of multiple slider inserts 110.

[0059] It is understandable that when there are two sets of transmission rods 210, both sets of transmission rods 210 are connected to the drive push plate 230. The drive cylinder 250 drives the drive push plate 230 to move, which can drive both sets of transmission rods 210 to move at the same time. Since there are swing arms 120 on both sets of transmission rods 210, the swing arms 120 on both sets of transmission rods 210 can be driven to swing at the same time. This simplifies the structure, avoids the repeated setting of drive components 200, and avoids increasing the mold size, making the structure simpler.

[0060] It should be noted that, for external parts such as air conditioners and refrigerators, which have many regular hole or groove structures, the core-pulling mechanism provided by this utility model can greatly optimize the structure of the core-pulling mechanism.

[0061] In some embodiments of this utility model, the drive cylinder 250 is fixed by a fixing seat 240.
