For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1 The embodiment of the present application provides an injection mold 100, the injection mold 100 includes a first insert 10, a second insert 20 and a snap-fit ​​component 30, and the injection mold 100 is used for injection molding products.

[0050] See also Figure 2 and Figure 3The second insert 20 is arranged opposite to the first insert 10 and is open and matched. The second insert 20 is used to cooperate with the first insert 10 to inject products, and the second insert 20 is provided with a through groove 21 and an opening 22. The through groove 21 penetrates the second insert 20 along the direction from the second insert 20 to the first insert 10, and the opening 22 is provided on the side of the second insert 20 away from the first insert 10 and communicates with the through groove 21. One end of the fastener 30 is movably provided in the first insert 10 and the through groove 21, and the other end of the fastener 30 rotates from the outside of the opening 22 to the inside of the opening 22 and abuts against the groove bottom of the opening 22, so as to lock the second insert 20 to the first insert 10.

[0051] When the injection mold 100 is closed, the operator rotates the fastener 30 from outside the opening 22 to inside the opening 22, so that the fastener 30 abuts against the groove bottom of the opening 22 to lock the second insert 20 to the first insert 10. When the injection mold 100 is opened, the operator rotates the fastener 30 out of the opening 22 to release the second insert 20 and the first insert 10 from each other to remove the product between the first insert 10 and the second insert 20. In this way, by controlling the fastener 30 to rotate in or out of the opening 22, the locking operation and the loosening operation of the second insert 20 and the first insert 10 are realized, which can simplify the closing and opening processes of the injection mold 100, thereby improving the efficiency of replacing the inserts of the injection mold 100 and demolding the injection molded product.

[0052] Understandable, see Figure 1 The injection mold 100 further includes an upper mold 101 and a lower mold 102. The upper mold 101 and the lower mold 102 are arranged opposite to each other and are open and matched. The upper mold 101 covers the first insert 10 so as to press the first insert 10 and the second insert 20 against the lower mold 102 when the mold is closed. Optionally, when the injection mold 100 is closed, the second insert 20 is first locked to the first insert 10 by the buckle 30, and then the locked first insert 10 and the first insert 10 are placed in the lower mold 102. Finally, the upper mold 101 is closed with the lower mold 102 carrying the first insert 10 and the second insert 20 to form a product by injection molding. When the injection mold 100 is opened, the upper mold 101 and the lower mold 102 are opened first, and then the locked first insert 10 and the second insert 20 are taken out of the lower mold 102. Finally, the latch 30 is rotated outward from the opening 22 to loosen the first insert 10 and the second insert 20, and the first insert 10 and the second insert 20 are opened to take out the molded product from between the first insert 10 and the second insert 20.

[0053] See also Figure 3 and Figure 4In some embodiments, the buckle 30 includes a connecting sleeve 31, a buckle portion 32 and a locking portion 33. The connecting sleeve 31 is movably inserted into the first insert 10 and the through slot 21, and the buckle portion 32 is arranged in a direction perpendicular to the extending direction of the connecting sleeve 31 and is located at one end of the connecting sleeve 31 adjacent to the second insert 20. The locking portion 33 is inserted into the connecting sleeve 31 and is threadedly connected to the buckle portion 32, so that the connecting sleeve 31 and the buckle portion 32 are detachably connected.

[0054] Thus, by setting the specific structure of the above-mentioned snap-fit ​​member 30, the connecting sleeve 31 and the snap-fit ​​portion 32 can form a detachable connection structure, which facilitates the assembly of the snap-fit ​​member 30 to the first insert 10, simplifies the assembly process, and also facilitates the maintenance of the injection mold 100.

[0055] In some embodiments, the buckle portion 32 is provided with an avoidance groove 321 , which is arranged adjacent to the connecting sleeve 31 and located on the side of the buckle portion 32 facing the first insert 10 , and is used to avoid the connection between the through groove 21 and the opening 22 .

[0056] In this way, by providing the above-mentioned avoidance groove 321, during the process of the buckle part 32 rotating to the opening 22, the avoidance groove 321 can avoid the connection between the through groove 21 and the opening 22, thereby preventing the buckle part 32 from colliding with the first insert 10, facilitating the buckle part 32 to stably rotate into the opening 22, and improving the operation stability.

[0057] See also Figure 3 In some embodiments, a side of the buckle portion 32 facing the first insert 10 is provided with an abutment slope 322, and the bottom of the groove of the opening 22 is provided with an abutment adapter surface 221. When the buckle portion 32 is rotated into the opening 22, the abutment slope 322 slides and abuts against the abutment adapter surface 221.

[0058] In this way, when the buckle portion 32 is rotated into the opening 22, the buckle portion 32 and the opening 22 can achieve inclined sliding abutment through the abutting inclined surface 322 and the abutting matching surface 221. The inclined abutment effectively improves the friction between the buckle portion 32 and the groove bottom of the opening 22 relative to the plane contact, so that the buckle 30 can stably lock the second insert 20 to the first insert 10, avoiding the first insert 10 and the second insert 20 from shaking during the movement, thereby improving the locking stability of the buckle 30.

[0059] See also Figure 3 and Figure 4In some embodiments, one end of the connecting sleeve 31 is provided with four abutting grooves 311, and the four abutting grooves 311 are arranged at equal intervals on the circumference of the connecting sleeve 31. The injection mold 100 further includes a stopper 40, which is movably disposed on the first insert 10 in a direction perpendicular to the extending direction of the through groove 21. When the buckle 30 rotates into the opening 22, the stopper 40 elastically abuts against the abutting groove 311 to elastically limit the buckle 30.

[0060] In this way, when the injection mold 100 is in the open mold state or the closed mold state, the limit member 40 can be abutted against the corresponding abutting groove 311, so that the limit member 40 limits the fastener 30, preventing the fastener 30 from continuing to rotate when the injection mold 100 is in the open mold state or the closed mold state, which is beneficial to improving the stability of the opening and closing of the injection mold 100.

[0061] In some embodiments, the first insert 10 is provided with a mounting groove 11, and the mounting groove 11 is arranged in a direction perpendicular to the extending direction of the through groove 21. The limiting member 40 includes a limiting portion 41, a fixing portion 42 and an elastic portion 43, the fixing portion 42 is inserted into the mounting groove 11, one end of the elastic portion 43 is connected to the fixing portion 42, and the limiting portion 41 elastically abuts against the abutting groove 311 through the elastic portion 43. Exemplarily, the elastic portion 43 may be a spring.

[0062] In this way, when the latch 30 is switched between the locked state and the loosened state, the latch 30 in the rotation process can press the limiting portion 41 against the supporting groove 311 to compress the elastic portion 43, so that the latch 30 and the limiting portion 41 are loosened from each other. When the latch 30 switches to any state, the elastic portion 43 provides elastic force to drive the limiting portion 41 to insert into the corresponding supporting groove 311, thereby limiting the latch 30 and preventing the latch 30 from continuing to rotate, thereby improving the locking stability and the loosening stability.

[0063] See also Figure 4 In some embodiments, the connecting sleeve 31 is further provided with a slide groove 312 , which is provided between two adjacent abutting grooves 311 , and the slide groove 312 is used to receive the limiting portion 41 so as to rotate the connecting sleeve 31 to make the limiting portion 41 slide into the abutting groove 311 .

[0064] In some embodiments, the limiting member 40 further includes a guide portion 44 , which is disposed through the elastic portion 43 and connected to a side of the fixing portion 42 facing the elastic portion 43 , and is used to guide the elastic portion 43 .

[0065] In this way, by passing the guide portion 44 through the elastic portion 43, the guide portion 44 can guide the elastic portion 43, so that the elastic portion 43 is always compressed or reset along the extension direction of the installation groove 11, and then the elastic portion 43 stably provides elastic force and drives the limiting portion 41 to abut against the abutting groove 311, thereby further improving the limiting stability of the limiting member 40.

[0066] See also Figure 2 In some embodiments, the second insert 20 is further provided with a receiving groove 23, which is opened in the groove wall of the opening 22 and is adjacent to the middle of the second insert 20 relative to the opening 22. The side walls of the first insert 10 and the second insert 20 are both provided with a handle groove 12, which is used to remove the first insert 10 and the second insert 20. It can be understood that the handle groove 12 of the first insert 10 and the handle groove 12 of the second insert 20 can be connected when the mold is closed, so that the operator can stably drive the first insert 10 and the second insert 20 to move synchronously after the mold is closed.

[0067] Thus, by providing the above-mentioned receiving groove 23, when the first insert 10 and the second insert 20 are to be released from each other, the receiving groove 23 can provide a sufficiently large working space for the operator, so that the operator can directly push the fastener 30 located in the opening 22 out of the opening 22 through the receiving groove 23, thereby simplifying the difficulty of opening the mold of the first insert 10 and the second insert 20 and improving the working efficiency. In addition, by providing the above-mentioned handle groove 12, it is convenient for the operator to directly drive the first insert 10 and the second insert 20 to move through the handle groove 12, without using a complex manipulator or other transfer mechanism to drive the first insert 10 and the second insert 20 to move, thereby simplifying the mechanical structure of the first insert 10 and the second insert 20 and reducing the use cost at the same time.

[0068] The present application also provides an injection molding device (not shown), which includes a driving component (not shown) and the above-mentioned injection mold 100, and the driving component is used to drive the upper mold 101 and the lower mold 102 to open and close the mold.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
