[0024] The utility model will be further explained in detail in connection with the following examples:

[0025] The utility model will be further explained in detail in connection with the following examples:

[0026] As Figures 1 to 8 The utility model discloses a mould with one -way fixed injection moulding insert structure, is used to carding and positioning insert A, include: mould 1, a plurality of convex parts 11 are connected on the mould 1, and the first positioning slot 12 that can be used for insert carding is formed between two adjacent convex parts 11, and one of two adjacent convex parts 11 is provided with the carding piece 2, the carding piece 2 includes the main body part 21 connected to convex part 11 and the carding part 22 connected to the main body part 21, the carding part 22 is matched with the slot wall of first positioning slot 12 and is formed with the carding slot 300 that can be positioned with the carding piece, and the elastic part 23 that can produce deformation is further provided between the main body part 21 and the carding part 22, and when the carding part 22 is extruded by the insert, the elastic part 23 produces deformation, so that the insert can be carded into or separated from the carding slot 300.

[0027] When needing to position insert A, insert A is aligned with first positioning slot 12, then insert A is moved downwards, so that insert A gradually contacts the carding part 22 of carding piece 2, when the carding part 22 is abutted by insert A, the elastic part 23 produces deformation, at this time, insert A gradually passes the carding part 22, when insert A passes the carding part 23, the elastic part 23 resets and rebounds, so that the carding part 22 resets, and the carding part 22 can form the carding slot 300 with the slot wall of first positioning slot 12, so that insert A is positioned in the carding slot 300 by the carding piece, convenient to install, when the positioning of insert A is completed, the mould 1 is closed with other moulds, and injection molding processing is facilitated, and due to the cooperation of the carding piece 2 and the carding slot 300, the product can be applied to horizontal machine.

[0028] The width W1 of the elastic part 23 in the cross-sectional direction is smaller than the width W2 of the main body part 21 in the cross-sectional direction, and the width W1 of the elastic part 23 in the cross-sectional direction is smaller than the width W3 of the clamping part 22 in the cross-sectional direction. The width W1 of the elastic part 23 is smaller than the width W2 of the main body part 21 and the width W3 of the clamping part 22, so that the elastic part 23 can be deformed.

[0029] The side of the clamping part 22 adjacent to the elastic part 23 is provided with a first inclined surface 221 inclined upward, and the side of the clamping part 22 away from the elastic part 23 is provided with a second inclined surface 222 inclined downward, and one end of the second inclined surface 222 is connected with the first inclined surface 221. The first inclined surface 221 is arranged to facilitate the insertion of the insert A from above, and the second inclined surface 222 is arranged to facilitate the ejection of the insert A from the clamping groove 300, and the arrangement of the first inclined surface 221 and the second inclined surface 222 makes the insertion and removal of the insert A more smooth.

[0030] The second inclined surface 222 and the first inclined surface 221 are arranged at an angle, and the distance between the second inclined surface 222 and the first inclined surface 221 is convex from the side away from the insert to the side close to the insert. The second inclined surface 222 and the first inclined surface 221 are expanding at the connection, and the width here reaches the maximum. When the insert A moves from the first inclined surface 221 to the connection, the insert A presses the first inclined surface 221, and the elastic part 23 is deformed. When the insert A gradually passes the connection, the insert A gradually separates from the clamping part 22, so at this time the clamping part 22 is not stressed, the elastic part 23 returns to its original position, and the clamping part 22 is reset, thereby clamping the insert A in the clamping groove 300.

[0031] The protruding part 11 is provided with a groove 111 capable of accommodating the clamping part 2, and the main body part 21 is matched in size and shape with the groove 111. The groove 111 provided on the protruding part 11 facilitates the insertion of the clamping part 2, so that the clamping part 2 can be inserted into the protruding part 11, making the structure more compact and the space application more reasonable.

[0032] The clamping part 2 is detachably connected to the insert 1, so that when the clamping part 2 is damaged, it can be easily disassembled and replaced, reducing the cost.

[0033] The insert 1 is also provided with a receiving groove 13 capable of communicating with the groove, and the main body part 21 is provided with a connecting part 24 capable of being inserted into the receiving groove 13 and matched in size and shape with the receiving groove 13. The arrangement of the connecting part 24 and the receiving groove 13 facilitates the installation and positioning of the clamping part 2, so that the clamping part 2 can be inserted from the bottom surface of the insert 1, facilitating the positioning and installation.

[0034] The main body part 21, the clamping part 22, the elastic part 23 and the connecting part 24 are integrally formed. In this way, the structural strength of the clamping piece 2 is enhanced. Specifically, the forming mode can be turning forming or casting forming.

[0035] The mold core 1 is further provided with a plurality of cavities 14, and the protruding parts 11 are arranged in the cavities 14, so that there is enough space for the medium to wrap the insert A when injection molding.

[0036] The mold core 1 is further provided with a plurality of protruding clamping blocks 15, and the second positioning grooves 16 capable of clamping the insert are formed between the adjacent clamping blocks 15. The positioning of the plurality of clamping blocks 15 and the second positioning grooves 16 can position the different positions of the insert A, so that the insert A can be more accurately positioned on the mold core.

[0037] The mold core 1 is further provided with a clamping groove group 17 capable of clamping the insert, so that other parts of the insert A can be clamped and positioned, and the insert A is prevented from sliding relative to the mold core.
