Description

Technical Field

[0001] This utility model relates to a marking structure for castings. Background Technology

[0002] Casting lettering is widely used in the field of casting technology. During the casting production process, due to the need for product quality traceability, it is often necessary to cast information such as the manufacturer's logo and the model number and serial number of the casting onto the casting. Therefore, the markings on the casting model need to be changed frequently.

[0003] In existing typesetting molds, replacing the individual type blocks requires removing the entire typesetting mold from the casting mold body before replacing them. Therefore, type block replacement is necessary. While typical casting model numbers are in the form of company abbreviation letters and numbers, the company letter block usually doesn't need to be changed. However, replacing the type block often causes the letter block to move as well. Frequent movement and replacement of letter blocks increases wear on the typesetting mold and mold body, reducing their lifespan and increasing costs due to the need for replacement and maintenance. Furthermore, replacing type blocks involves multiple steps, is cumbersome, slow, and can easily lead to misalignment between type blocks, affecting the molding effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a casting marking structure that is not only reasonable in structure, but also stable in positioning and reduces cost.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a casting marking structure, including a core plate, wherein a horizontally inward-facing groove is provided on the side of the core plate, the top of the groove penetrates through the core plate, a fixed character block is inserted and fixedly provided in the groove away from the side opening, a movable character block is abutted to the outside of the fixed character block, the movable character block is inserted from the side opening and slidably fitted in the groove, a positioning block is abutted to the outside of the movable character block, the positioning block is fixed to the core plate by bolts to position the movable character block, a positioning protrusion protrudes from the outside of each movable character block, and positioning grooves are provided on the inside of the movable character block and the positioning inside for fitting the positioning protrusions.

[0006] Furthermore, the cross-section of the inlay groove is an isosceles trapezoid, and the cross-section of the movable type block is consistent with that of the inlay groove.

[0007] Furthermore, the core board has two ear slots that are symmetrically opened longitudinally at its side end and communicate with the end of the inlay slot. The movable type block has ears fixed on both sides longitudinally to be inserted into the ear slots. Both the ears and the ear slots have screw holes for bolting and locking.

[0008] Furthermore, the top of the stator block has a letter-shaped punch, and the top of the movable type block has a number-shaped punch. Both the number-shaped punch and the letter-shaped punch protrude from the inlay groove.

[0009] Furthermore, a base plate is fixed to the lower end of the core plate, and an upper mold that is snapped onto the base plate is covered on the top of the core plate. A sand-covering opening is provided on the top of the upper mold.

[0010] Compared with the prior art, the present invention has the following advantages: the positioning groove and the positioning protrusion can ensure that the positioning of each movable type block and the fixed type block is more precise and the gap is smaller, and effectively prevent the movable type block from shifting. The positioning block can prevent the movable type block from sliding out laterally from the inlay groove, thereby overcoming the problem of possible detachment during use.
