Description
Technical Field
[0001] This utility model relates to the field of electroplating disc casting mold technology, and in particular to a casting mold for filling and shrinking by opening a window in the inner cavity of an electroplating disc. Background Technology
[0002] Electroplating disc casting molds typically consist of two main parts, upper and lower, made of high-strength metal materials, featuring a robust and durable structure. Inside the mold, there are specialized cavities whose shape corresponds to the design of the casting, used to mold various metals or other materials. In the inner cavity area of the electroplating disc, the mold undergoes precision machining and polishing to ensure smooth material flow during the casting process and a smooth surface, facilitating subsequent electroplating treatment. The mold's internal design includes a reasonable parting surface to facilitate demolding and subsequent processing of the casting.
[0003] However, traditional molds are generally designed as a single piece and do not usually have a detachable or adjustable mold core. Once the mold is manufactured or damaged during use, it is difficult to make targeted adjustments or replacements. The mold can only be replaced or repaired as a whole, which limits its scope of application and affects the applicability and ease of use of the mold.
[0004] Therefore, those skilled in the art have provided a waist-opening feeding casting mold for the inner cavity of an electroplating disc to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waist-opening feeding casting mold for electroplating trays. This casting mold has a lower shaping mold core and a middle shaping mold core that are snap-fitted into the lower mold and upper mold, respectively. This allows users to install mold cores of suitable shapes according to casting requirements, thereby expanding the applicability of the casting mold. When casting defects or mold core damage occur, only the corresponding mold core needs to be removed, instead of disassembling the entire mold, saving time and maintenance costs. This reduces the time required for mold adjustment and repair, and improves the flexibility and response speed of the production line.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A shrinkage-compensating casting mold with a window opening in the inner cavity of an electroplating tray includes a base. A lower mold is provided in the middle of the upper surface of the base. The lower mold includes a fixed base plate. An mounting plate is snapped onto the upper surface of the fixed base plate. A lower shaping mold core is fixedly connected to the middle of the upper surface of the mounting plate. Both sides of the upper surface of the base are provided with a central mold. The central mold includes a limiting seat. A first electric telescopic rod is fixedly connected to the center of the outer wall of one side of the limiting seat. A side mounting shell is fixedly connected to the output end of the first electric telescopic rod. A central shaping mold core is snapped into the inner wall of the side mounting shell. A shaping groove is opened in the middle of the outer wall of one side of the central shaping mold core. A positioning slot is opened in the middle of the outer wall of the other side of the central shaping mold core. A positioning copper block is fixedly connected to the middle of the inner wall of one side of the side mounting shell. Multiple heat-conducting plates are fixedly connected to the inner wall of the positioning copper block. A heat-conducting air duct is fixedly connected to the inner wall of the heat-conducting plate. A fan is fixedly connected to one side of the outer wall of the rear end of the side mounting shell. An upper mold is provided at the rear end of the upper surface of the base. The upper mold includes a support frame. A second electric telescopic rod is fixedly connected to the front end of the upper surface of the support frame. A connecting frame is fixedly connected to the output end of the second electric telescopic rod. A top plate is fixedly connected to the lower surface of the connecting frame.
[0007] Through the above technical solution, the casting mold has a positioning copper block in the middle mold, which, together with the heat conduction plate, guides and stores the heat generated after the casting mold is processed, thereby avoiding local overheating or uneven temperature. Finally, under the action of the fan, the heat is guided to the outside by the heat conduction duct. The slow cooling, combined with the conduction of the positioning copper block, can maintain the stability and uniformity of the mold temperature, thereby improving the quality of the casting.
[0008] Furthermore, the fixed base plate is fixedly connected to the center of the upper surface of the base, and sealing gaskets are fixedly connected around the upper surface of the fixed base plate. The above technical solution improves the sealing performance between the lower mold and the middle mold.
[0009] Furthermore, multiple first screws are fixedly connected to the four sides of the middle part of the upper surface of the fixed base plate, and the upper end of the outer wall of the first screw is threaded with a first nut. Multiple first positioning grooves are opened on the four sides of the upper surface of the mounting plate. The above technical solution enables the mounting plate to install and fix the lower shaping mold core bolts onto the fixed base plate.
[0010] Furthermore, the limiting seats are respectively fixedly connected to both sides of the middle of the upper surface of the base, and the front and rear ends of the outer wall of the side mounting shell near the first electric telescopic rod are fixedly connected to the limiting slide rods. The limiting slide rods are slidably connected to the limiting seats, and the front and rear ends of the outer wall of the side mounting shell away from the first electric telescopic rod are fixedly connected to the rubber pads. Through the above technical solution, the first electric telescopic rod can be controlled to move the side mounting shell in a relatively stable manner through the limiting slide rod, and the rubber pad is used to improve the sealing performance when the two side mounting shells are closed.
[0011] Furthermore, a second screw is fixedly connected to the front end and the rear end of the inner wall of the side mounting shell, and a second nut is threaded onto the outer wall of the second screw. A second positioning groove is provided at the upper and lower parts of the front end and the rear end of the outer wall of the middle shaping mold core. The above technical solution enables the central shaping mold core to be bolted and fixed to the side mounting shell.
[0012] Furthermore, the outer walls of the front and rear ends of the central shaping mold core are provided with mounting slots, the inner walls of the front and rear ends of the side mounting shell are fixedly connected with mounting blocks, the positioning copper block is engaged with the positioning slots, and the output end of the fan is fixedly connected to the heat-conducting air duct. Through the above technical solution, the central shaping mold core can be engaged with the side mounting shell by the interlocking action of the mounting slot and the mounting block. This allows the fan to guide the heat of the positioning copper block through the heat conduction air pipe for slow discharge, avoiding rapid cooling that could affect the shaping material.
[0013] Furthermore, the support frame is fixedly connected to the rear end of the upper surface of the base, and a connecting groove is provided in the middle of the outer wall of the rear end of the support frame; The above technical solution enables the injection pipe to rise or fall relatively smoothly through the connecting groove.
[0014] Furthermore, a material injection pipe is fixedly connected to the middle of the upper surface of the top plate, a heating module is fixedly connected to the rear end of the upper surface of the top plate, and multiple exhaust ports are opened around the middle of the upper surface of the top plate. The above technical solution enables the heating module to heat and insulate the injection tube it wraps, thereby reducing the possibility of liquid material solidifying inside the injection tube, and the exhaust port can discharge the gas entering the shaping tank.
[0015] This utility model has the following beneficial effects: 1. This utility model proposes a waist-opening shrinkage-compensating casting mold for the inner cavity of an electroplating tray. Compared with most traditional electroplating tray molds with waist-opening shrinkage-compensating molds, this casting mold has a lower shaping mold core and a middle shaping mold core that are snap-fitted into the lower mold and upper mold, respectively. This allows the user to install a mold core of a suitable shape according to the casting requirements, thereby increasing the applicability of the casting mold. When casting defects or mold core damage occur, only the corresponding mold core needs to be removed, instead of removing the entire mold, saving time and maintenance costs. This reduces the time for mold adjustment and repair, and improves the flexibility and response speed of the production line.
[0016] 2. The present invention proposes a mid-cavity window-opening shrinkage-compensating casting mold for electroplating trays. Compared with most traditional mid-cavity window-opening shrinkage-compensating casting molds for electroplating trays, this casting mold has a positioning copper block set in the middle of the mold. Together with a heat-conducting plate, it guides and stores the heat generated after the casting mold is processed, thereby avoiding local overheating or uneven temperature. Finally, under the action of a fan, the heat is guided to the outside by a heat-conducting air duct. The slow cooling, combined with the conduction of the positioning copper block, can maintain the stability and uniformity of the mold temperature, thereby improving the quality of the casting.

[0024] Reference Figure 1 , Figure 2 and Figure 3The support frame 401 is fixedly connected to the rear end of the middle part of the upper surface of the base 1. A connecting groove 402 is provided in the middle of the outer wall of the rear end of the support frame 401, so that the injection tube 406 can rise or fall relatively smoothly through the connecting groove 402. The injection tube 406 is fixedly connected to the middle part of the upper surface of the top plate 405.

[0025] Working principle: First, select the required shape of the middle shaping mold core 308 and the lower shaping mold core 207.

Then, fix it by the threaded engagement between the second nut 307 and the second screw 306. Similarly, install and fix the lower shaping mold core 207 onto the fixed base plate 201. When the equipment is started, the first electric telescopic rod 302 is activated, controlling the side mounting shells 303 on both sides. The opposing movements bring the two middle shaping mold cores 308 and the lower shaping mold core 207 together to form the complete shaping groove 309. Finally, the top plate 405 is placed on the middle mold 3 and the lower mold 2 under the push of the second electric telescopic rod 403. Then, the liquid material is injected into the complete shaping groove 309 through the injection pipe 406 to form the required shape. The positioning copper block 3014 absorbs and stores heat, and then conducts it to the middle shaping mold core 308 in a relatively comprehensive and uniform manner. Driven by the fan 3017 (EBM PapstG1G 100), the external airflow circulates in the heat conduction air pipe 3016. The heat conduction air pipe 3016, together with the heat conduction plate 3015, guides and discharges the heat in the positioning copper block 3014, thereby assisting the mold in heat dissipation. The heating module 407 can reduce the possibility of liquid material solidifying in the injection pipe 406 by connecting an external power source.
