Description

Technical Field

[0001] This utility model relates to the field of mold design and manufacturing, and in particular to a mold for manufacturing the outer frame of a bank teller machine display screen. Background Technology

[0002] As a crucial component of ATMs, the outer frame of a bank teller machine not only protects and supports the display screen but also directly affects the overall structural strength and appearance quality of the machine. Therefore, the injection molds used to produce these frames must possess high precision, strong stability, and smooth demolding. Especially in mass production, the mold's structural design has a decisive impact on molding efficiency, finished product consistency, and production costs.

[0003] Existing molds used for molding the outer frame of ATM displays often rely on external hydraulic systems to drive the core-pulling mechanism when handling lateral grooves or undercut structures. This results in complex structures, high manufacturing costs, inconvenient maintenance, and a tendency for mold jamming and part breakage during repeated molding processes. Furthermore, some molds still require manual demolding, which is not only inefficient but also poses certain safety hazards, failing to meet the dual requirements of efficiency and reliability for modern automated production lines.

[0004] To address this issue, a mold for manufacturing the outer frame of a bank teller machine display screen is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mold for manufacturing the outer frame of a bank teller machine display screen, which aims to improve the problems of complex side core pulling, low demolding efficiency, and difficult structural maintenance of existing molds.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mold for manufacturing the outer frame of a bank teller machine display screen, comprising a mold blank base plate, a pin base plate fixedly connected to the top of the mold blank base plate, two mold blank square irons fixedly connected to the top of the mold blank base plate and symmetrically distributed, a pin plate fixedly connected to the top of the pin base plate, a plurality of pin plate return springs fixedly connected to the top of the pin plate, a mold blank B plate fixedly connected to the top of the mold blank B plate, a plurality of inclined ejectors fixedly connected to the top of the mold blank B plate, a plurality of pins fixedly connected to the top of the mold blank B plate, two sliders symmetrically distributed on the top of the mold blank B plate, a plurality of inclined guide pillars fixedly connected to the top of the sliders, a mold blank A plate on the top of the mold blank B plate, and a nozzle installed in the middle of the mold blank A plate.

[0007] As a further description of the above technical solution:

[0008] The ejector plate reset springs are evenly distributed on the top of the ejector plate to provide uniform elastic force to the ejector plate.

[0009] As a further description of the above technical solution:

[0010] The inclined ejectors are symmetrically arranged and work in conjunction with the ejector pins to smoothly eject the molded part from the mold.

[0011] As a further description of the above technical solution:

[0012] The nozzle is connected to the injection molding machine and is used to inject molten plastic into the mold cavity. The nozzle is sealed with the mold groove on the mold blank A plate to prevent leakage.

[0013] As a further description of the above technical solution:

[0014] Multiple positioning pins are provided between mold plate A and mold plate B to achieve precise alignment during mold closing.

[0015] As a further description of the above technical solution:

[0016] The mold blank A plate has mold grooves on both sides.

[0017] As a further description of the above technical solution:

[0018] The mold blank B plate has a rear mold core installed in the middle, and the outer frame of the bank teller machine display screen is set on the outside of the rear mold core. Guide posts are fixedly connected to the four corners of the top of the mold blank B plate.

[0019] As a further description of the above technical solution:

[0020] The guide post is inserted inside the mold plate A.

[0021] This utility model has the following beneficial effects:

[0022] This invention employs a linkage structure between a slider and an inclined guide post to achieve automatic core-pulling and demolding of the lateral structure of the product, achieving the technical effect of rapid lateral release without manual assistance. Compared with traditional molds where the concave side part requires manual disassembly or uses a complex hydraulic structure, this significantly improves demolding efficiency, reduces structural complexity, avoids errors and safety hazards caused by human intervention, and solves the fundamental problems of existing technologies where lateral core-pulling relies on external systems and is costly and has a high failure rate.

[0023] This invention achieves highly efficient demolding through the coordinated operation of the angled ejector and ejector pins. In traditional molds, product damage or jamming can easily occur during demolding, while this solution effectively prevents these problems, improving production efficiency and product molding quality.

[0024] This invention employs a multi-positioning pin precision alignment technology, achieving high-precision positioning during mold closing. Compared to existing mold structures that rely solely on a single positioning pin, this solution addresses the issues of large mold alignment errors and inconsistent part dimensions, ensuring accuracy and stability in each molding process.

[0032] Reference Figures 1-4This utility model provides an embodiment of a mold for manufacturing the outer frame of a bank teller machine display screen, including a mold base plate 6, a pin base plate 8 fixedly connected to the top of the mold base plate 6, two mold square iron pieces 5 fixedly connected to the top of the mold base plate 6 and symmetrically distributed, a pin plate 9 fixedly connected to the top of the pin base plate 8, a plurality of pin plate return springs 7 fixedly connected to the top of the pin plate 9, a mold B plate 4 fixedly connected to the top of the mold square iron pieces 5, a plurality of inclined ejectors 14 fixedly connected to the top of the mold B plate 4, a plurality of ejector pins 13 fixedly connected to the top of the mold B plate 4, two sliders 10 symmetrically distributed on the top of the mold B plate 4, a plurality of inclined guide pillars 11 fixedly connected to the top of the sliders 10, a mold A plate 1 on the top of the mold B plate 4, and a nozzle installed in the middle of the mold A plate 1. 2. The ejector plate return springs 7 are evenly distributed on the top of the ejector plate 9 to provide uniform elastic force to the ejector plate 9. The inclined ejectors 14 are symmetrically arranged and work together with the ejector pins 13 to smoothly push the molded part out of the mold. The nozzle 2 is connected to the injection molding machine and is used to inject molten plastic into the mold cavity. The nozzle 2 is sealed with the mold groove 3 on the mold blank A plate 1 to prevent leakage. Multiple positioning pins 12 are set between the mold blank A plate 1 and the mold blank B plate 4 to achieve precise alignment during the mold closing process. Mold grooves 3 are opened on both sides of the mold blank A plate 1. The rear mold core 17 is installed in the middle of the mold blank B plate 4. The outer frame body 16 of the bank teller machine display screen is set on the outside of the rear mold core 17. The four corners of the top of the mold blank B plate 4 are fixedly connected with guide pins 15, which are inserted into the inside of the mold blank A plate 1.

[0033] The mold base plate 6 serves as the fundamental support structure for the entire mold, bearing all upper components and providing overall structural stability. The ejector base plate 8 is fixedly mounted on the mold base plate 6, undertaking the installation and guiding functions of the ejector mechanism, ensuring stable movement of the ejection mechanism. Two symmetrically arranged mold base square iron plates 5 are fixedly connected to the mold base plate 6, supporting the mold base plate B 4 and ensuring the verticality and rigidity of the mold structure. The ejector plate 9 is mounted on the ejector base plate 8, bearing and guiding the vertical movement of the ejector pins 13. Multiple ejector plate return springs 7 are fixed to the top of the ejector plate 9, providing a restoring force after demolding, allowing the ejector plate 9 to return to its initial position, ensuring the continuity of cyclic molding operations. The mold base plate B 4 is fixed above the mold base square iron plates 5, serving as the intermediate clamping structure of the mold, used to install multiple actuating mechanisms such as the slider 10, the angled ejector 14, and the ejector pins 13. The angled ejector 14 is fixed to the top of the mold blank B plate 4, arranged symmetrically, and works in conjunction with the ejector pins 13 to smoothly eject the molded part with a side concave structure from the mold, preventing damage during demolding. Multiple ejector pins 13 are also mounted on the mold blank B plate 4, providing vertical ejection force after molding to eject the product from the cavity. Two sliders 10 are provided on the top of the mold blank B plate 4, arranged symmetrically, for lateral parting action and to release the side structure of the product through sliding. Multiple angled guide pillars 11 are mounted on the top of the sliders 10, guiding the sliders 10 to move in a predetermined direction, realizing lateral core-pulling action during mold opening or demolding. The mold blank A plate 1 is mounted on the top of the mold blank B plate 4, serving as the upper mold plate. A nozzle 2 is located in the middle of its structure, connected to the injection molding machine, for accurately injecting molten plastic into the mold cavity. The nozzle 2 and the mold groove 3 on the mold blank A plate 1 are sealed together to prevent material leakage during injection molding. The mold blank A plate 1 has mold grooves 3 on both sides for centering and positioning with the nozzle 2. Multiple positioning pins 12 are also provided between the mold blank A plate 1 and the mold blank B plate 4 to achieve precise positioning during mold closing, avoid misalignment, ensure mold cavity alignment accuracy, and thus improve the dimensional consistency and quality stability of the molded parts. The rear mold core 17 is installed in the middle of the mold blank B plate 4 and is one of the key molding components of the mold cavity. It directly forms the back structure of the display screen frame and is a core element affecting the molding size and accuracy. The main body 16 of the bank teller machine display screen frame is located outside the rear mold core 17 and is the actual contour area of ​​the product formed by the mold. Through cooperation with other walls of the mold cavity, it forms a complete product shape structure. Guide pins 15 are inserted into the mold blank A plate 1 to ensure precise mold alignment and ensure precise alignment of all components during mold closing, avoiding errors.

[0034] Working Principle: In the production of the outer frame for a bank teller machine display screen, firstly, during the mold closing stage, mold blank A plate 1 and mold blank B plate 4 are aligned under the closing force of the injection molding machine. Simultaneously, multiple positioning pins 12 positioned between them achieve precise alignment, ensuring a tight seal in the mold cavity. The nozzle 2 is sealed to the mold groove 3 on mold blank A plate 1 and connected to the injection molding machine. Molten plastic is then injected from the nozzle 2 into the closed mold cavity, filling the entire cavity. After injection molding, the process enters the pressure holding and cooling stage. The plastic cools and solidifies within the mold cavity. The mold blank base plate 6, mold blank B plate 4, and mold blank A plate 1 act as a structural frame, bearing the molding pressure and maintaining the stability of the mold cavity dimensions.

[0035] After cooling, the mold begins to open. Under the pulling force of the injection molding machine, mold blank A plate 1 moves upward, opening the mold, while mold blank B plate 4 and mold blank base plate 6 remain stationary. During this process, the slider 10 located at the top of mold blank B plate 4 slides laterally under the guidance of the inclined guide post 11, thereby causing the inclined ejector 14 embedded on the side of the product to move to both sides, releasing the concave structure of the product. Next, the ejection mechanism, composed of the ejector base plate 8 and ejector plate 9, begins to operate. The ejector plate return spring 7 releases its elastic force under compression, pushing the ejector plate 9 upward, simultaneously causing the multiple ejector pins 13 mounted on it to rise, thereby ejecting the molded product from the mold cavity. The inclined ejector 14 and ejector pins 13 work together to provide both vertical and lateral demolding forces during the ejection process, ensuring the complete removal of the molded part.

[0036] After the main body 16 of the bank teller machine display screen is completely ejected, the ejector pins 13 and slanted ejectors 14 automatically return to their original positions under the elastic force of the ejector plate return spring 7, and the ejector plate 9 and ejector base plate 8 return to their initial positions. The slider 10 also returns to its original position under the guidance of the slanted guide post 11, ready for the next round of molding operations. The entire mold structure ensures the vertical support stability of the mold blank B plate 4 through the mold blank square iron 5. The components coordinate with each other and move in a continuous manner, which significantly improves the demolding efficiency and molding quality of the mold, and is particularly suitable for the mass production of injection molded parts such as bank teller machine display screen frames with side concave structures.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
