Description

Technical Field

[0001] This utility model relates to the field of molding machines, specifically to a vertical molding machine. Background Technology

[0002] Existing horizontal parting molding machines employ a horizontal sand-shooting design. During sand shooting, the sand needs to be fed into the sand-shooting mechanism from the side sand magazine through a 90-degree angle. This angled design weakens the sand-shooting force, affecting the quality of the sand mold. Furthermore, the sand-shooting mechanism and the sand magazine require a movable sealing connection, and the sealing structure is prone to wear, leading to air and sand leakage.

[0003] While vertical parting flaskless injection molding machines offer high production efficiency, their "flaskless" nature makes them ineffective in addressing the expansion problem of sand molds during casting. Even with a flask, the rectangular shape of existing sand molds and the gap between the flask and the flask prevent the flask from effectively containing sand mold expansion. Therefore, a new type of vertical parting molding machine is needed, employing a taller and longer injection box design to reduce overall space requirements. The compact layout of the vertical parting improves processing efficiency and reduces energy consumption and failure rates. This new molding machine effectively solves the problems of insufficient injection force, high sand mold costs, and inability to control sand mold expansion inherent in existing technologies, meeting the requirements of modern production.

[0018] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0019] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] like Figure 1-4 As shown, a specific embodiment of this utility model is a vertical molding machine. The molding chamber 1 includes an upper sand box 101, an upper pressure plate, a lower pressure plate, a lower drive cylinder 102, a lower sand box 103, and a lifting rod 104. The upper sand box 101 is slidably mounted on the lifting rod 104 via a sliding sleeve, and the lower sand box 103 is also slidably mounted on the lifting rod 104 via a sliding sleeve. The lower drive cylinder 102 is drivenly connected to the lower pressure plate. The sand-shooting module 4 protrudes from the top of the frame 2, and the sand nozzles of the sand-shooting module 4 can respectively interact with the upper... The sand box 101 and the lower sand box 103 correspond to each other. Each side of the sand shooting module 4 is provided with an upper drive cylinder 105, which is driven and connected to the upper pressure plate. The sand shooting module 4 is composed of a sand shooting bucket 401, a movable seal 402 and a sand shooting box 403. The sand shooting box 403 is provided with at least one air inlet 404 that can be connected to an air compressor. The sand shooting bucket 401 is located on the top of the sand shooting box 403, and the movable seal 402 is installed between the sand shooting bucket 401 and the sand shooting box 403.

[0021] The upper and lower sand boxes slide on the lifting rod via sliding sleeves, making the up-and-down movement of the sand boxes smoother, reducing swaying during movement, and improving molding accuracy. The lower drive cylinder is connected to the lower pressure plate, and the extension and retraction of the drive cylinder controls the up-and-down movement of the lower pressure plate, thereby compacting the sand mold. The sand outlets of the sand-shooting module correspond to the upper and lower sand boxes respectively, ensuring that the sand is evenly injected into the sand boxes and avoiding uneven sand distribution. The upper drive cylinders on both sides of the sand-shooting module are connected to the upper pressure plate, and the extension and retraction of the upper drive cylinders controls the up-and-down movement of the upper pressure plate, further enhancing the compaction effect of the sand mold. The sand-shooting module consists of a sand-shooting hopper, a movable seal, and a sand-shooting box. The sand-shooting hopper is located on top of the sand-shooting box, and the movable seal is installed between the sand-shooting hopper and the sand-shooting box, ensuring sealing during the sand-shooting process and preventing sand leakage. The air inlet on the sand-shooting box can be connected to an air compressor, which uses compressed air to shoot sand into the sand box, improving the efficiency and power of sand shooting.

[0022] Specifically, the sand-shooting module's design allows sand to enter the sand box vertically, avoiding the problem of sand needing to enter the sand-shooting mechanism through a 90-degree turn, as in traditional horizontal sand-shooting designs. This reduces the loss of shooting force and improves the quality of the sand mold. Furthermore, the compact layout and vertical parting design of the sand-shooting module not only reduce the overall space occupied but also improve processing efficiency and reduce energy consumption and failure rate. Through the compact vertical parting layout, the expansion problem of the sand mold is effectively controlled, avoiding the problem in existing technologies where the casing cannot limit sand mold expansion.

[0023] Therefore, the vertical molding machine of this application effectively solves the problems of insufficient sand shooting force, high sand mold cost, and inability to control sand mold expansion in the prior art by optimizing the structural design of the sand shooting module and molding chamber, thus meeting the requirements of modern production.

[0024] Furthermore, the sand cleaning chamber 3 includes a mold frame 301, a discharge plate 302, a slide rail 303, a telescopic cylinder 304, and a sand cleaning table 305. The telescopic cylinder 304 is drivenly connected to the discharge plate 302. The mold frame 301 is slidably installed on the slide rail 303. The sand cleaning table 305 is located below the telescopic cylinder 304, and a sand storage box is provided inside the sand cleaning table 305.

[0025] Specifically, the movable door makes operating the sand cleaning chamber more convenient, the observation window facilitates real-time monitoring of the sand cleaning process, and the handle further enhances operational ease of use. The nylon bristles of the brush effectively remove residual sand from the sand mold surface, ensuring a high-quality cleaning effect. The sand storage box facilitates the collection of cleaned sand for subsequent reuse.

[0026] Therefore, this technical solution improves the efficiency and convenience of sand cleaning operations by optimizing the structure of the sand cleaning chamber. The design of the movable door and observation window allows operators to monitor the sand cleaning process more intuitively, improving operational accuracy. The nylon bristle structure of the brush section ensures thorough sand cleaning, reduces residual sand on the mold surface, and improves mold quality. The sand storage box enables sand recycling, reducing production costs. Compared with existing technologies, this solution has significant advantages in sand cleaning efficiency and mold quality.

[0027] Furthermore, the front of the molding room 1 is also equipped with a fixing slot 5, within which a control panel 6 is installed. Specifically, the control panel allows operators to intuitively operate the equipment and adjust parameters, improving the convenience and accuracy of operation.

[0028] Furthermore, a hydraulic pump station 7 for controlling the delivery of hydraulic oil is also installed on one side of the sand cleaning chamber 3. A cooling fan and heat dissipation fins are installed above the hydraulic pump station 7. An overflow valve (model: DBW10A-1-30B / 315-6EG24N9K4) and a pressure sensor (model: HM28-2X / 350BAR) are also installed on the hydraulic pump station. This technical solution effectively solves the problem of excessive oil temperature that may occur in the hydraulic system of the sand cleaning chamber during long-term operation by setting up an oil pump station and a cooling fan. The oil pump station can stably deliver hydraulic oil, ensuring the normal operation of the hydraulic actuators in the sand cleaning chamber, while the cooling fan can dissipate heat in a timely manner, preventing the oil pump station from overheating and affecting the performance of the hydraulic system. Compared with existing technologies, this solution not only improves the stability of the hydraulic system but also extends the service life of the oil pump station and reduces the equipment failure rate, thereby improving the working efficiency and reliability of the sand cleaning chamber. The design of the heat dissipation fins effectively reduces the internal temperature of the control box, preventing equipment failure due to overheating and extending the service life of the equipment. This design enables the molding machine to maintain efficient and stable operation even in high-temperature environments, solving the problem of equipment performance degradation caused by poor heat dissipation in existing technologies.

[0029] Furthermore, the sand cleaning chamber 3 also includes a movable door 306, which is slidably installed on the frame 2. The movable door 306 is also equipped with an observation window 307 and a handle 308.

[0030] The movable door design allows operators to monitor the sand removal process in real time through an observation window, ensuring the accuracy and safety of the operation. The handle design facilitates manual opening and closing of the movable door, improving operational convenience. The sliding installation of the movable door allows it to move smoothly on the frame, reducing its footprint within the sand removal chamber and facilitating maintenance and cleaning.

[0031] Specifically, the hatch can be made of aluminum alloy to improve its durability and lightness. The observation window can be made of tempered glass to ensure safety and transparency. The handle can have a non-slip design to increase operational comfort and safety.

[0032] Therefore, the technical solution of this application solves the problems of inconvenient operation and difficult monitoring of the sand cleaning chamber in the prior art by introducing a movable hatch. The sliding installation of the movable hatch and the design of the observation window not only improve the convenience and safety of operation, but also optimize the space utilization of the sand cleaning chamber, making the entire sand cleaning process more efficient and reliable.

[0033] Furthermore, a main control module 8 is also installed on one side of the molding chamber 1. The movable seal 402 includes a solenoid valve. The oil pump station and the solenoid valve are electrically connected to the main control module 8. The main control module contains a main controller (model: FX5U-32MT / ES), a power supply module (model: FX5U-PSU-30M), an analog input module (model: FX5-8AV), an analog output module (model: FX5-8YV), and a digital input / output module (model: FX5-32ET / ES). The main control module controls the hydraulic oil delivery of the oil pump station and the opening and closing of the solenoid valve, thereby achieving the sealing of the sand-shooting module and the automated control of the sand-shooting process. The solenoid valve, as part of the movable seal, can quickly open or close as needed during the sand-shooting process, ensuring the sealing of the sand-shooting box and preventing air and sand leakage. The electrical connection between the oil pump station and the main control module allows for precise adjustment of the hydraulic oil delivery according to actual needs, further improving the operating efficiency of the equipment.

[0034] Specifically, the solenoid valve can be a normally closed structure. When the main control module receives the sand-shooting signal, the solenoid valve opens rapidly, allowing the sand in the sand-shooting box to enter the upper or lower sand box through the sand outlet. After sand-shooting is completed, the solenoid valve closes immediately to ensure that the air pressure in the sand-shooting box remains stable. The oil pump station, controlled by the main control module, can automatically adjust the hydraulic oil delivery rate according to pressure changes during the sand-shooting process, thereby ensuring the stability of the sand-shooting force and the uniformity of the sand mold quality.

[0035] Through the above technical solution, this application effectively solves the problems of insufficient sand-shooting force and easy wear of the sealing structure leading to air and sand leakage in the prior art. The introduction of the main control module makes the sand-shooting process more automated, reduces manual intervention, and improves production efficiency. The coordinated work of the solenoid valve and the oil pump station ensures the stability and sealing of the sand-shooting process, reduces the equipment failure rate, and reduces sand waste, further reducing production costs.

[0036] Furthermore, a row of cleaning brushes is provided below the discharge plate 302, and the brushes are made of nylon bristles. The brushes effectively remove residual sand from the discharge plate, ensuring its cleanliness and preventing sand accumulation from affecting subsequent operations. The nylon bristles are wear-resistant and flexible, reducing wear on the discharge plate during cleaning and improving cleaning efficiency.

[0037] Specifically, the brush unit can be mounted below the discharge plate using a fixed bracket. The bracket can be adjusted according to the size and shape of the discharge plate to ensure that the brush unit covers the entire surface of the discharge plate. As a preferred embodiment, the brush unit can be designed as a detachable structure for easy maintenance and replacement. Furthermore, the nylon bristles of the brush unit can be selected with different densities and lengths to adapt to the sand cleaning requirements of different abrasives.

[0038] Therefore, this technical solution, by incorporating a brush unit, solves the problem of incomplete sand removal from the discharge plate, improving sand removal efficiency and the cleanliness of the discharge plate. Compared with existing technologies, this solution is not only simple in structure and easy to implement, but also extends the service life of the brush unit by using a nylon bristle structure, reducing maintenance costs and further enhancing the overall performance of the equipment.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
