Since two accessories 2 need to be installed, the two accessories 2 need to be installed on the inner wall 12 of a groove 11 opened in the longitudinal direction. Since the groove width of the groove 11 is narrow, the processing drill bit cannot enter the groove 11, so it is impossible to open a locking hole on the inner wall 12 of the groove 11. In order to install the accessory 2, the prior art is to fix the extended fixing part 21 of the accessory 2 by screws 3 on the non-stress-bearing surface of the accessory 2 (the drill bit can process the non-stress-bearing surface), and then fix and lock the accessory 2. The stress-bearing surface of the accessory 2 is the side corresponding to or located on the inner wall 12 of the groove 11. Since the locking direction of the accessory 2 is inconsistent with the stress-bearing direction, problems such as screw 3 breakage, accessory displacement and increased gap will occur during use.

[0025] The utility model discloses a specific implementation of a locking structure for a non-machined surface of an injection mold, see Figures 2 to 3 , including a mold body 41, a mold accessory 5, a locking and fixing block 6 and a locking piece 8.

[0026] In this embodiment, the mold body 41 is provided with a groove 42 arranged along the longitudinal direction, and the machinable surface of the mold body 41 is provided with an installation groove 44 arranged along the longitudinal direction. The installation groove 44 extends laterally to the groove wall 43 of the groove 42. The plane where the groove wall 43 is located is the force-bearing surface of the mold accessory 5, and its force direction is perpendicular to the groove wall 43 of the groove 42.

[0027] In this embodiment, the mold accessory 5 includes an accessory seat 52 and an accessory body 51, and the accessory body 51 is detachably mounted on the accessory body 51, and the detachable mounting method can be achieved by screw locking. In the assembled state, the mold accessory 5 is placed in the mounting groove 44. The force-bearing surface of the accessory body 51 is flush with the groove wall 43 of the groove 42, and the force-bearing direction of the accessory body 51 is perpendicular to the force-bearing surface of the accessory body 51. The outer side surface of the accessory seat 52 is flush with the machinable surface of the mold body 41.

[0028] As a further improvement, the locking and fixing block 6 is detachably mounted on the bottom of the mounting groove 44. Optionally, a mounting hole 45 is provided on the machinable surface of the mold body 41, and the locking and fixing block 6 is inserted into the mounting hole 45. The hole wall of the mounting hole 45 is provided with a mounting channel 46 that leads to the bottom of the mounting groove 44. In this embodiment, the locking and fixing block 6 is provided with a locking hole 61, and the locking hole 61 is aligned with the mounting channel 46, which can be understood as the locking hole 61 and the mounting channel 46 are coaxially arranged.

[0029] In this embodiment, the locking member 8 is used for fixed connection between the mold accessory 5 and the locking fixing block 6 in the force direction of the mold accessory 5. Specifically, the accessory seat 52 of the mold accessory 5 is provided with a through hole 53 aligned with the locking hole 61 in the transverse direction. In the assembled state, the locking member 8 passes through the through hole 53 and the installation channel 46 in sequence and is fixedly connected with the locking hole 61, thereby realizing the fixed connection between the accessory seat 52 and the locking fixing block 6.

[0030] In order to protect the locking and fixing block 6 and prevent the locking and fixing block 6 from escaping from the mounting hole 45, the mold body 41 is also provided with a cover plate 7, which is detachably mounted on the machinable surface of the mold body 41 so that the cover plate 7 covers the mounting hole 45. Similarly, the cover plate 7 can be detachably mounted on the mold body 41 by screws.

[0031] Furthermore, in order to facilitate the removal of the locking and fixing block 6 from the mounting hole 45, a blind hole 62 is provided on the front end surface of the locking and fixing block 6, and an auxiliary tool such as an external latch or an L-shaped pin can be inserted into the blind hole 62, so that the locking and fixing block 6 can be removed when space is limited. As a preferred solution, the cross-sectional shape of the locking and fixing block 6 is circular, and the locking and fixing block 6 of this structure is more convenient to process and prepare.

[0032] In this embodiment, the side of the locking hole 61 provided in the locking fixing block 6 is a plane, the inner wall surface of the mounting hole 45 corresponding to the plane is also a plane, and the plane of the mounting hole 45 is provided with a mounting channel 46. The plane of the locking fixing block 6 and the plane of the mounting hole 45 cooperate with each other, and the position of the locking hole 61 can be positioned, so that the locking hole 61 and the mounting channel 46 are precisely aligned, so that the locking member 8 can quickly pass through the mounting channel 46 to connect the locking hole 61, and the plane of the locking fixing block 6 and the plane of the mounting hole 45 cooperate with each other, and can also prevent the locking fixing block 6 from rotating in the mounting hole 45, thereby realizing the circumferential rotation positioning of the locking fixing block 6.

[0033] The locking structure of the non-machined surface of the injection mold of this embodiment is provided with an installation groove 44 arranged along the longitudinal direction through the machined surface of the mold body 41, and the installation groove 44 extends laterally to the groove wall 43 of the groove 42, and then the mold accessory 5 is fixed in the installation groove 44 by locking the fixing block 6 and the locking member 8. Compared with the prior art, the locking direction of the original mold accessory 5 is changed so that the actual force direction of the mold accessory 5 of this application is consistent with the direction in which it is locked by the locking member 8, which solves the problem of the locking member 8 breaking, the displacement of the mold accessory 5 and the increase of the gap due to the inconsistency between the locking direction and the force direction. The overall structure is simple and compact, the processing is convenient and quick, and it is more convenient for subsequent maintenance of the mold.

[0034] Finally, it should be noted that the locking structure of the non-machined surface of the injection mold disclosed in the embodiment of the utility model is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, rather than to limit it.
