[0002] Glass molds are tools used to produce various glass products. Designed with specific shapes and dimensions, they allow the raw glass to soften at high temperatures and solidify in the mold after cooling, ultimately forming the desired glass product. Glass molds play a crucial role in the glass manufacturing industry, directly impacting product quality, yield, and cost.

[0003] The design and manufacture of glass molds is a complex process that requires consideration of factors such as the mold's material, thermal expansion coefficient, cooling system, and wear and high-temperature resistance. To extend the lifespan of glass molds, when designing an embedded cast nickel core glass mold, a contoured nickel core layer is embedded within the mold's inner cavity, forming a molding cavity within the contoured nickel core layer. The contoured nickel core layer typically has multiple embedded blocks positioned at the lower portion of its outer wall. These blocks extend axially and are concentrated in the central region of the contoured nickel core layer. This can lead to significant variations in circumferential shrinkage during mold forming, and can cause deformation of the mold's upper end face after cooling. Utility Model Content

[0030] See also Figures 1 to 6 The present invention provides a mold for casting imitation nickel core glass. The mold for casting imitation nickel core glass comprises a mold body 100, an imitation nickel core layer 200 and two positioning leveling plates 300.

[0031] The interior of the mold body 100 is provided with an installation cavity 110, and a circumferential positioning groove is arranged around the installation cavity 110, and assembly grooves 114 are respectively opened on both sides of the installation cavity 110; the interior of the imitation nickel core layer 200 is provided with a forming cavity 210, and the imitation nickel core layer 200 is located in the installation cavity 110, and the outer wall of the imitation nickel core layer 200 is circumferentially provided with circumferential positioning blocks, and the circumferential positioning blocks are inserted into the circumferential positioning grooves, and axial positioning blocks 214 are respectively provided on both sides of the outer wall of the imitation nickel core layer 200, and the axial positioning blocks 214 are inserted into the assembly grooves 114; two positioning leveling plates 300 are respectively inserted into the two assembly grooves 114, and the positioning leveling plates 300 are fixed in the assembly grooves 114 through multiple connecting parts 400.

[0032] Compared to the prior art, the present invention provides a cast-in imitation nickel core glass mold. A core is placed in the assembly groove 114 and molding cavity 210 of the mold body 100. Molten metal wraps the imitation nickel core layer 200 and molds the mold body 100. Circumferential positioning grooves are formed at positions on the mold body 100 corresponding to the circumferential positioning blocks. After the core collapses, the assembly groove 114 and molding cavity 210 are formed. Subsequently, two positioning plates 300 are inserted into the corresponding assembly grooves 114, and the positioning plates 300 are positioned using multiple connectors 400. Finally, the parting surface is formed by machining the upper end surface of the mold. At this time, the imitation nickel core layer 200 is embedded in the mold body 100, and the circumferential positioning block can reduce the difference in circumferential shrinkage of the mold body 100. The positioning leveling plate 300 is used to press the axial positioning block 214 to avoid the problem of axial rotation of the imitation nickel core layer 200 due to poor fusion effect. At the same time, the upper end surface of the positioning leveling plate 300 is processed to ensure that the upper end surface of the mold body 100 meets the requirements of the parting surface.

[0033] Specifically, the circumferential positioning groove includes an end positioning groove 111, a middle positioning groove 112, and a tail positioning groove 113 arranged in sequence from the end to the tail, and the assembly groove 114 is vertically connected to the end of the middle positioning groove 112; the circumferential positioning block includes an end positioning block 211, a middle positioning block 212, and a tail positioning block 213 arranged in sequence from the end to the tail, and the axial positioning block 214 is vertically connected to the end of the middle positioning block 212; the end positioning block 211 is plug-fitted with the end positioning groove 111, the middle positioning block 212 is plug-fitted with the middle positioning groove 112, and the tail positioning block 213 is plug-fitted with the tail positioning groove 113. The end positioning block 211, the middle positioning block 212, and the tail positioning block 213 can form multiple circumferential positioning structures spaced axially apart, and can form bonding areas at different axial positions to improve the structural strength of the imitation nickel core layer 200 and the mold body 100.

[0034] Preferably, the middle positioning groove 112 is connected to the assembly groove 114 , so that the positioning plate 300 can be directly pressed on the middle positioning block 212 .

[0035] See also Figure 3 and Figure 4 There are two central positioning grooves 112 and two central positioning blocks 212. The two ends of the assembly groove 114 are perpendicularly connected to the two central positioning grooves 112, and the two ends of the axial positioning block 214 are perpendicularly connected to the two central positioning blocks 212. The two central positioning blocks 212 and the axial positioning blocks 214 are perpendicularly connected to each other to form a doorframe-like structure, which can improve the structural strength of the molded nickel core layer 200 and the mold body 100.

[0036] See also Figure 3 and Figure 4 One side of the tail positioning block 213 has an inclined outer side surface 2131, which is perpendicular to the tail arc surface of the molded nickel core layer 200. One side of the tail positioning groove 113 has an inclined inner side surface 1131, which is perpendicular to the tail arc surface of the installation cavity 110. The inclined outer side surface 2131 on one side of the tail positioning block 213 can prevent the tail positioning block 213 and the molded nickel core layer 200 from forming a sharp angle structure, which would reduce the bonding strength of the molten metal.

[0037] Among them, the connecting part 400 is a connecting bolt, which passes through the positioning plate 300 and is threadedly connected to the bottom of the assembly groove 114. The positioning plate 300 is tightened and positioned by the connecting bolt, which can press the axial positioning block 214 of the molded nickel core layer 200 to prevent the molded nickel core layer 200 from axial rotation.

[0038] See also Figure 6 The upper end surface of the positioning and leveling plate 300 is provided with a plurality of countersunk holes 310 and a plurality of through holes 320. The plurality of countersunk holes 310 and the plurality of through holes 320 are coaxially arranged one by one. The connecting bolts pass through the through holes 320 from top to bottom and the nut ends of the connecting bolts are located in the countersunk holes 310. When processing the upper end surface of the positioning and leveling plate 300, the nut ends of the connecting bolts will not be processed.

[0039] The outer side of the positioning plate 300 has an external conforming curved surface 330 that conforms to the outer side of the mold body 100. The inner side of the positioning plate 300 has an internal conforming curved surface 340 that conforms to the outer side of the contoured nickel core layer 200. Once the positioning plate 300 is securely connected, the outer side of the positioning plate 300 conforms to the outer side of the mold body 100, ensuring a consistent appearance. The inner side of the positioning plate 300 conforms to the outer side of the contoured nickel core layer 200, preventing gaps that could affect molding.

[0040] The lower end of the internal conformal arc surface 340 is provided with an adapting notch 350 for avoiding the axial positioning block 214. The upper end surface of the adapting notch 350 is used to press the axial positioning block 214, and the inner side surface of the adapting notch 350 is used to support the axis positioning block, so that the axial positioning block 214 always maintains a stable state.

[0041] Furthermore, to ensure that the upper end surface (parting surface) of the mold body 100 meets the requirements, the upper end surface of the positioning plate 300 is machined and leveled, thereby forming a conformal machining surface 360 ​​on the upper end surface of the positioning plate 300. It is worth noting that the conformal machining surface 360 ​​here is not a planar structure, but rather needs to be configured to conform to the parting surface of the mold body 100.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
