Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 3, the present embodiment provides a dual misalignment-preventing typecasting mechanism for a mold, including a mold hole 1 on a mold plate and a typecasting insert 2 embedded in the mold hole 1, wherein in order to improve the utilization rate of the typecasting insert 2, the typecasting insert 2 includes an insert body 21 and a typecasting block 22, for the case of a large number of numbered characters, the typecasting block 22 includes a plurality of typecasting sub-pieces 221, one or a plurality of character symbols are engraved on the upper surface of each typecasting sub-piece 221, and the required number contents can be pieced together by arranging the typecasting sub-pieces 221 in different orders.

Firstly, referring to fig. 1, a first anti-misalignment mechanism 3 is disposed between the molding strip body 21 and the die hole 1, a notch 31 is disposed on an outer bottom wall of the molding strip body 21, a protrusion 32 is disposed at a corresponding position of the die hole 1, and when the molding strip body 21 is inserted into the die hole 1 in a correct direction, the notch 31 and the protrusion 32 are matched; when the molding body 21 is inserted into the molding hole 1 in other directions, the protrusion 32 interferes with the outer bottom wall of the molding body 21, and the molding body 21 cannot be assembled. The panel body 21 is used for bearing all numbering information, and is provided with a notch 31 and a bulge 32, so that the numbering is ensured to be correct in the overall direction;

next, referring to fig. 4, a second anti-misalignment mechanism 4 is disposed between the gib body 21 and the insert block 22. Two opposite side edges of the inlaid strip body 21 are respectively folded upwards to form vertical edges 211, the character casting block 22 is installed between the two vertical edges 211 in a sliding mode, straight ribs 41 are arranged on the inner bottom wall of the inlaid strip body 21 along the length direction, corresponding channels 42 are arranged at the bottom of the character casting block 22, and when the character casting block 22 slides into the space between the two vertical edges 211 in the correct direction, the ribs 41 are matched with the channels 42; when the character casting block 22 is connected in a sliding mode in other directions, the ribs 41 abut against the side face of the character casting block 22, and the character casting block 22 cannot be assembled; the provision of the ribs 41 and channels 42 ensures that each of the lettering blocks 22 is correctly mounted, thereby ensuring that the orientation of each character within the numbering is correct.

Specifically, with continued reference to fig. 1, for the first anti-misalignment mechanism 3, the protrusion 32 is located at a position outside the center of the die hole 1, preferably on one side of the die hole 1, so as to overcome the problem of universal matching of the center position and ensure that the protrusion 32 can perform the function of checking the orientation of the gib body 21.

The shape of the protrusion 32 and the notch 31 includes, but is not limited to, a rectangle, an arc, and a slope. In order to improve the matching accuracy, the protrusion 32 of the present embodiment is preferably a square block, and the notch 31 is preferably a right-angled notch with corresponding size.

The gib body 21 is connected with the die hole 1 in an interference fit manner, so that the cross-sectional dimension of the gib body 21 is slightly larger than that of the die hole 1. Due to the above-mentioned structural connection characteristics, the total length formed by splicing the character blocks 22 should be equal to the length of the insert body 21 so as not to protrude too much and affect the connection between the insert body 21 and the die hole 1, and after the insert body 21 is inserted into the die hole 1, the inner side wall of the die hole 1 tightly presses the two sides of the character block 22, so that the character block 22 is stably installed.

With continued reference to fig. 4, for the second anti-misalignment mechanism 4, in order to achieve the desired anti-misalignment effect, the ribs 41 must be located at positions other than the center line of the insert body 21, because when the ribs 41 are located at the center line, they have no influence on the orientation of the word-setting block 22, and the grooves 42 can be matched with the ribs 41 regardless of forward or reverse sliding, so that the ribs 41 need to be located at the areas near the side edges to interfere with the word-setting block 22 installed reversely.

Because the character embedding block 22 is installed or detached with the gib body in a sliding mode, the channel 42 penetrates through the bottom wall of the character embedding block 22 along the length direction so as to avoid clamping during sliding.

Further, the cross section of the rib 41 is a protruding semicircle, and the cross section of the channel 42 is an invaginated semicircle, so that the smooth connection of the character inlaying block 22 is promoted by using the smooth surface of the fillet.

In a preferred embodiment, the vertical sides 211 extend upward and gradually thicken toward the inside of the insert body 21, an inverted trapezoidal gap is formed between the two vertical sides 211, and the cross section of the character block 22 has a regular trapezoidal shape with corresponding dimensions. Thus, the vertical edge 211 not only serves as a travel guide for the block 22, but also forms a narrowing structure at the bottom, so that the longitudinal movement of the block 22 can be limited by the structure of the vertical edge, and the block is prevented from falling off in the pressing process.

Of course, the vertical edge 211 may also be longitudinally limited in other forms, for example, the top of the vertical edge 211 may be provided with an inward-facing convex tooth 5 (see fig. 5), and the convex tooth 5 abuts against the top wall of the character casting block 22 to perform a basic positioning function. In the embodiment, a trapezoidal matching mode is preferably adopted, so that the action characteristics of wider trapezoidal surface contact surface and more stable guiding are further taken, the shaking of the character casting block 22 during reciprocating stamping is reduced, and the processing quality of character casting pressing is optimized.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
