Currently, traditional casting anode copper master molds have significant technical defects in practical applications: the master mold consists of a base plate and a cover plate, with a casting cavity formed between them. The assembly and handling of the master mold are extremely inconvenient during use. Furthermore, under repeated heating and cooling, the mold experiences repeated large thermal expansion and cooling contraction strains. The heating and cooling times and rates vary in different parts, resulting in varying degrees of thermal expansion on the inner and outer surfaces, causing uneven deformation volume. Weaker parts of the mold are prone to premature failure, leading to premature scrapping of the entire mold. Summary of the Invention

Example

[0020] As attached Figure 1 To be continued Figure 2 As shown: This embodiment provides a master mold for casting anode copper plates, including a base plate 1, an annular frame 2, and a cover plate 3. The upper surface of the base plate 1 is a square flat plate with a raised master mold surface 101 in the middle. The lower surface of the base plate 1 is provided with several reinforcing ribs. The reinforcing ribs are honeycomb-shaped, which improves the structural strength of the base plate and enhances heat dissipation performance. The base plate 1 is chamfered around its perimeter, which reduces weight and reduces sharp corners to ensure safety.

[0021] Among them, the annular frame 2 is square and surrounds the middle to form the mother model cavity, and has several reinforcing ribs on the outside. The mother model cavity is adapted according to the design requirements. The reinforcing ribs improve the structural strength of the annular frame 2 on the one hand, and form a hollow structure to enhance heat dissipation performance on the other hand. The annular frame 2 also has chamfers around its perimeter, which also reduces weight and ensures safety.

[0022] The lower surface of the cover plate 3 is a square flat plate, and the middle of the cover plate 3 is provided with a casting hole 301. The upper surface of the cover plate 3 is provided with several reinforcing ribs. The reinforcing ribs improve the structural strength of the cover plate 3 on the one hand, and enhance the heat dissipation performance of the cover plate 3 on the other hand. The cover plate 3 is also provided with chamfers around its perimeter, which also reduces weight and ensures safety.

[0023] Among them, the annular frame 2 is placed above the base plate 1, and the cover plate 3 is placed on the annular frame 2. The upper surface of the base plate 1, the mother model surface 101, the inner wall of the annular frame 2 and the lower surface of the cover plate 3 constitute the mother mold casting cavity. The base plate 1 is flush with the outer edge of the annular frame 2 for positioning. The connection between the annular frame 2 and the cover plate 3 is limited by corresponding pin holes and first positioning pins 5. The number and position of the first positioning pins 5 are not limited, as long as they can achieve the positioning effect. In the figure of this embodiment, there is one on each side of the surface of the annular frame 2.

[0024] A push rod 4 is provided between the mother model surface 101 and the cover plate 3. The two ends of the push rod 4 are respectively inserted into the mother model surface 101 and the cover plate 3. One push rod 4 is positioned between the mother model surface 101 and the cover plate 3, near the center of the two ear-shaped movable blocks 1011 on the mother model surface 101. The mother model surface 101 has pin holes, and the corresponding cover plate 3 has push rod holes 305. The bottom of the push rod 4 has a pin inserted into the pin hole for fixation, and the top of the push rod 4 is inserted into the push rod hole 305 for fixation. The push rod serves two purposes: providing support and forming a pre-reserved casting through hole within the cast anode copper plate mold.

[0025] The mother model surface 101 has ear-shaped movable blocks 1011 at both ends. The ear-shaped movable blocks 1011 at the ear positions of the mother model surface 101 can be replaced when the ear is damaged by high temperature or cold shrinkage compression, thus doubling the mold life of the same material, maximizing energy saving of the same material, reducing production costs, and improving the utilization value of resources.

[0026] The cover plate 3 is provided with four lifting ears 302, which are evenly distributed on the reinforcing ribs on the surface of the cover plate 3. The bottom plate 1 has two lifting columns 102 on each side. The lifting ears 302 and the lifting columns 102 can facilitate the disassembly and transportation of the mold. Example

[0027] As attached Figure 3 To be continued Figure 7As shown: This embodiment provides a master mold for casting anode copper plates. The difference from Embodiment 1 is that in this embodiment, the annular frame 2 and the cover plate 3 are separate structures. Specifically: In this embodiment, the annular frame 2 is formed by a left frame 21, a right frame 22, a top frame 23, and a bottom frame 24. A frame clamp 201 is provided between adjacent frames to clamp and fix the edges of adjacent frames. Dividing the annular frame 2 into 4 pieces facilitates processing, further reduces weight, facilitates the handling of individual frame pieces, and the gaps between the joints further alleviate the stress caused by thermal expansion and contraction during casting, thus improving the service life of the mold.

[0028] The upper frame 23 has protruding bevels 231 at both ends on its inner side, while the left frame 21 and the right frame 22 have recessed left grooves 211 and right grooves 221 on their inner sides, respectively. The design of the bevels 231, left grooves 211, and right grooves 221 can reduce the cavity volume. Through innovative design of the mold cavity shape and copper liquid flow channel, the copper liquid can be filled more evenly, reducing redundant copper material consumption.

[0029] The upper frame 23 and lower frame 24 each have a second positioning pin 202 at the center of their inner sidewalls, which serves to position the cast anode copper plate mold. Figure 7 The trapezoidal part protruding from the lower surface of the middle cover plate 3 is actually a three-dimensional frustum, which can form a groove on the cast anode copper plate mold and play a positioning role. Positioning points of different shapes, sizes and positions can be designed according to different positioning requirements, but this patent does not require them.

[0030] The cover plate 3 is clamped to the edge of the annular frame 2 by a first cover plate clamp 303. In this embodiment, there are 8 first cover plate clamps 303, with 2 on each side.

[0031] The cover plate 3 is divided into two parts: a front cover plate 31 and a rear cover plate 32. A third locating pin 6 is provided at the joint between the front cover plate 31 and the rear cover plate 32 for limiting movement, and they are clamped by second cover plate clamps 304 on both sides. In this embodiment, there are two second cover plate clamps 304, one on each side. Dividing the cover plate 3 into two parts facilitates processing, further reduces weight, and makes it easier to handle individual cover plates. Furthermore, the gap between the parts can alleviate stress caused by thermal expansion and contraction during casting, thus extending the service life of the cover plate.

[0032] Two push rods 4 are provided between the mother model surface 101 and the rear cover plate 32. The two push rods 4 are respectively set near the two movable blocks 1011. The mother model surface 101 has two pin holes, and the corresponding rear cover plate 32 has two push rod holes 305. The bottom of the push rod 4 has a pin that is inserted into the pin hole for fixation, and the top of the push rod 4 is inserted into the push rod hole 305 for fixation. The push rods 4 serve two purposes: firstly, to support the rear cover plate 32, and secondly, to form two pre-reserved casting through holes in the cast anode copper plate mold.

[0033] Among them, the frame clamp 201, the first cover plate clamp 303, and the second cover plate clamp 304 are provided with inclined sharp blocks between the clamped objects, which can make the clamping secure.

[0034] How to use: When the base plate 1 needs to be placed on a flat position, the left frame 21, right frame 22, upper frame 23 and lower frame 24 are aligned and assembled on the surface of the base plate 1 in sequence, with the outer edges of the frames flush with the outer edges of the base plate. The frames are clamped with the frame clamp 201, and the top rod 4 is inserted into the pin hole of the mother model surface 101 for fixation. Then the front cover plate 31 and the rear cover plate 32 are placed on the frames in sequence. The four frames and two cover plates are clamped with the first cover plate clamp 303, and the front cover plate 31 and the rear cover plate 32 are clamped with the second cover plate clamp 304. Finally, the mold can be preheated for casting.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of the utility model without departing from the scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
