[0015] The beneficial effects of the utility model are:

[0016] (1) The utility model provides a first guide groove on the die and a second guide groove on the guide sleeve. The first guide groove, the second guide groove and the positioning member cooperate to ensure that the guide sleeve is accurately installed on the die. The die is then used to position and guide the punch to ensure that the mold as a whole is installed in place, thereby avoiding misalignment and resulting in unqualified workpieces.

[0017] (2) In the present invention, two first guide grooves are provided and are located on opposite sides of the upper end surface of the die. Correspondingly, two second guide grooves are provided on the guide sleeve. The guide sleeve can be positioned and fixed by two positioning members, thereby further ensuring the position accuracy of the guide sleeve during installation.

[0018] (3) In the present invention, the two first guide grooves are both elliptical, and the long axes of the two first guide grooves are perpendicular to each other, which can ensure the positioning effect in different horizontal directions and further ensure the position accuracy when the guide sleeve is installed.

[0023] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below according to specific implementation methods and in combination with the accompanying drawings.

[0024] Figure 1A cross-sectional schematic diagram of a mold guide device with an error-proofing function provided in an embodiment of the present application. The device comprises a die 1, a guide sleeve 3, a positioning member 5 and a punch 6. The die 1 and the guide sleeve 3 are fixed by the positioning member 5, and then the guide sleeve 3 guides the punch 6 to prevent misalignment during mold installation.

[0025] For details, see Figure 2 The cross-sectional shape of the die 1 is roughly circular. Two first guide grooves 2 are provided on the upper end surface of the die 1. The two first guide grooves 2 are respectively located on opposite sides of the upper end surface of the die 1, that is, the two first guide grooves 2 are located on the same diameter of the circle where the upper end surface of the groove is located, and are both close to the side of the die 1.

[0026] In this embodiment, the cross-sectional shape of the first guide grooves 2 is an ellipse, and the long axes of the two first guide grooves 2 are perpendicular to each other.

[0027] The guide sleeve 3 is detachably mounted on the die 1. Figure 2 The outer cross-sectional shape of the guide sleeve 3 matches the cross-sectional shape of the die 1. A second guide groove 4 is provided on the guide sleeve 3 at a position corresponding to the first guide groove 2, and the second guide groove 4 is aligned with the first guide groove 2 along the docking direction of the guide sleeve 3 and the die 1.

[0028] It should be noted that the second guide groove 4 is provided on the side of the guide sleeve 3 facing the die 1. Figure 1 For example, the second guide groove 4 is provided on the lower end surface of the guide sleeve 3.

[0029] The positioning member 5 is detachably mounted in the first guide groove 2. It should be noted that the height of the positioning member 5 is greater than the depth of the first guide groove 2. In this way, when the guide sleeve 3 is mounted on the die 1, the upper end of the positioning member 5 can extend into the second guide groove 4, thereby positioning and fixing the position of the guide sleeve 3.

[0030] In this embodiment, the cross-sectional shape of the positioning member 5 is the same as that of the first guide groove 2, that is, it is also elliptical. By matching the shapes of the positioning member 5 with the first guide groove 2 and the second guide groove 4, the position stability of the guide sleeve 3 when installed on the die 1 can be further ensured.

[0031] The shape of the punch 6 is the same as the cross-sectional shape of the guide hole 7 inside the guide sleeve 3. Figure 2 The punch 6 is roughly circular in shape, and a straight edge is provided on both sides of the circle and the lower end. Correspondingly, the cross-sectional shape of the guide hole 7 inside the guide sleeve 3 is also roughly circular, and a straight edge is provided on both sides of the circle and the lower end. In this way, when the guide sleeve 3 is fixedly installed on the die 1, the guide hole 7 inside the guide sleeve 3 can guide the punch 6 to avoid misalignment when the punch 6 and the die 1 are connected.

[0032] Therefore, the technical solution of the present application positions the guide sleeve 3 through the positioning piece 5, so that the guide sleeve 3 can be accurately installed on the die 1, and then the punch 6 is positioned and guided by the die 1 to ensure that the entire mold is installed in place and avoid misalignment that may cause the workpiece 8 to be unqualified.

[0033] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
