DETAILED DESCRIPTION

[0029] To address the issues described in the background art, the present invention provides a mold for an automotive connector. The following, combined with the accompanying drawings, provides a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments represent only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] See also Figure 1-3 , this embodiment provides a molding die for an automotive connector, comprising:

[0031] Mould machine 10;

[0032] The fixed injection mold 30 is arranged on the mold machine 10;

[0033] The movable injection mold 20 is arranged above the fixed injection mold 30;

[0034] The mold part 40 is fixed inside the injection mold 20;

[0035] The locking mechanism 50 is provided at the contact end between the mold part 40 and the movable injection mold 20 , and is used to lock the mold part 40 on the movable injection mold 20 .

[0036] Specifically, the locking mechanism 50 includes:

[0037] A first locking block 51 is provided at the bottom end of the mold part 40;

[0038] A second locking block 52 is provided at a position corresponding to the first locking block 51;

[0039] The corresponding positions are that both are on the same horizontal line inside the mold part 40 and are symmetrically placed about the spring 53;

[0040] The spring 53 is provided at the bottom end of the mold part 40 and connects the first locking block 51 and the second locking block 52; the spring 53 pushes the first locking block 51 and the second locking block 52 to expand outward to complete the locking;

[0041] A first stopper 54 is provided at the contact end between the movable injection mold 20 and the mold part 40;

[0042] The second stopper 55 is provided at the contact end between the movable injection mold 20 and the mold part 40;

[0043] a blocking plate 56 , provided on the mold part 40 ;

[0044] The concave corner 57 is provided at the blocking end where the blocking plate 56 contacts the movable injection mold 20 .

[0045] Specifically, the blocking plate 56 provided on the mold part 40 and the concave corner 57 provided on the blocking end of the movable injection mold 20 do not generate a gap exceeding the dimensional tolerance after contact.

[0046] Specifically, after the first locking block 51 and the second locking block 52 arranged at the bottom of the mold part 40 complete the locking of the mold part 40, the first locking block 51 and the second locking block 52 respectively contact the first blocking block 54 and the second blocking block 55 to limit the mold part 40 from moving outward.

[0047] Specifically, the first locking block 51 and the second locking block 52 arranged at the bottom end of the mold part 40, and the tops of the first blocking block 54 and the second blocking block 55 arranged at the contact end between the injection movable mold 20 and the mold part 40 are all smooth semicircular or arc-shaped protrusions, which reduce the resistance of the mold part 40 to entering the injection movable mold 20.

[0048] When using:

[0049] When the staff is ready to start the injection molding work, the mold part 40 is aligned with the notch on the injection movable mold 20 and the mold part 40 is pressed in. When the bottom end of the mold part 40 enters the injection movable mold 20, the spring 53 of the locking mechanism 50 pushes the first locking block 51 and the second locking block 52 to expand outward; when the first locking block 51 and the second locking block 52 reach the first stop block 54 and the second stop block 55, the mold part 40 continues to move downward due to the pressure. After the first locking block 51 and the second locking block 52 are subjected to the pressure on the inclined surfaces of the first stop block 54 and the second stop block 55, the spring 53 is compressed, and the first locking block 51 and the second locking block 52 shrink inward. When the middle position is reached, the semicircular heads between the components contact each other, ensuring that the first locking block 51 and the second locking block 52 can move smoothly into the interior of the injection movable mold 20. When it moves to the bottom, the concave corner 57 will stop the blocking plate 56 from continuing to move downward. At this time, the first locking block 51 and the second locking block 52 are in contact with the first blocking block 54 and the second blocking block 55. The upper and lower parts lock the mold part 40 to prevent the mold part 40 from shaking.

[0050] After the fixation is completed, the movable injection mold 20 is aligned with the fixed injection mold 30 on the mold machine 10 and closed, and then injection molding is performed.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
