[0001] This utility model relates to the field of mold and injection molding technology, and more specifically to an injection mold with a quick-release insert. Background Technology

[0002] Injection molds generally consist of an upper mold and a lower mold. Injection molding is a processing method used for the mass production of certain complex-shaped parts. It involves injecting molten plastic into the mold cavity under high pressure using an injection molding machine. After cooling and solidification, the molded product is obtained. In modern injection molding production, the application fields of plastic products are becoming increasingly widespread, and the speed of product updates is also accelerating. This places higher demands on the performance and flexibility of injection molds.

[0003] like Figure 1 As shown, in the injection molding of products, it is sometimes necessary to embed a slanted copper nut in the product. However, in the existing injection mold, in order to meet the requirement of slanted copper nut, the movement direction of the slanted slider 19 must be consistent with the axis of the copper nut when the upper mold and the lower mold open. The slanted slider 19 needs to move at an angle. The positioning of the slanted slider 19 and the insert 20, due to the effect of the tilting force, will cause loosening, resulting in damage to the mold. Utility Model Content

[0026] like Figures 2 to 5 As shown, this utility model discloses an injection mold with a quick-release insert, comprising an upper mold 1, a lower mold 2, a drive assembly 3, and an insert assembly 4. The upper mold 1 is connected to the lower mold 2, forming an injection space between them for injection molding a product 5. The insert assembly 4 is mounted on the drive assembly 3, which is located on the lower mold 2. The drive assembly 3 drives the insert assembly 4 to move, and the insert assembly 4 is connected to the product 5. The insert assembly 4 includes a separable oblique insert structure. The drive assembly 3 drives the insert assembly 4 to move, and through the design of the insert assembly 4, the original oblique motion is changed to linear motion, increasing the compactness of the positioning between the drive assembly 3 and the insert assembly 4, while preventing the slider from loosening and damaging the mold during mold opening, thus increasing the service life of the mold.

[0027] The drive assembly 3 includes a drive cylinder 6, an outer slider 7, and an inner slider 8. The lower mold 2 is provided with a moving groove 10.

The outer slider 7 and the inner slider 8 are set in the moving groove 10 and move horizontally along the moving groove 10. The drive cylinder 6 is connected to the outer slider 7. The outer slider 7 is fixedly connected to the inner slider 8 by a positioning screw. The extension and retraction of the drive cylinder 6 drives the outer slider 7 to move along the moving groove 10, thereby driving the inner slider 8 to move together. The insert assembly 4 is installed on the inner slider 8. Before the product 5 is injected, the drive cylinder 6 drives the outer slider 7 and the inner slider 8 to move. The inner slider 8 moves the insert assembly 4, which is fitted with a copper nut 18, to the injection position.

[0028] The insert assembly 4 includes insert one 12 and insert two 13. Insert one 12 and insert two 13 are snapped together. Insert one 12 is installed on the inner slider 8 in the drive assembly 3. Insert two 13 is connected to the injection molded product 5. The inner slider 8 is provided with a positioning hole 9 for installing a positioning ball. Insert one 12 is provided with a positioning groove 16, and the positioning ball abuts in the positioning groove 16. The positioning ball is used to achieve the positioning and installation of insert one 12 and inner slider 8.

[0029] In this utility model, the second insert 13 is obliquely arranged, the first insert 12 is provided with a snap-fit ​​part 14, the second insert 13 is provided with a snap-fit ​​groove 15, the first insert 12 is snapped into the snap-fit ​​groove 15 through the snap-fit ​​part 14, and the first insert 12 is in a horizontal state after being snapped into the second insert 13.

[0030] Insert 2 13 is provided with a threaded part 17, which is used to fit a copper nut 18. The copper nut 18 is used to form an embedded connection structure during product injection molding.

[0031] The operation steps of this utility model are as follows;

[0032] When the injection-molded product 5 needs to be inlaid with a copper nut 18, firstly, the copper nut 18 is screwed onto the threaded part 17 of the insert 2 13. Then, the insert 2 13 is snapped into the insert 1 12. The insert 1 12 is installed in the inner slider 8 and positioned by a positioning ball. Then, the outer slider 7 and the inner slider 8 are driven inward by the drive cylinder 6 to send the copper nut 18 to the designed position. Then, injection molding begins. After the product 5 is injection molded, the upper mold 1 and the lower mold 2 separate. The drive cylinder 6 moves to drive the outer slider 7 and the inner slider 8 to move along the moving groove 10. At this time, since the insert 2 13 is connected to the injection-molded product 5, when the inner slider 8 moves outward, the positioning ball will disengage from the positioning groove 16 of the insert 1 12 until the inner slider 8 separates from the insert group 4. Then, the injection-molded product 5 is taken out, and the insert 2 13 is unscrewed from the copper nut 18.
