Description

Technical Field

[0001] This utility model relates to the field of core-making machine technology, specifically a dual-station single-shot sand head core-making machine that enables continuous core making. Background Technology

[0002] Sand core making machines are core equipment used in the foundry industry for manufacturing sand cores. They use a sand injection head to inject core sand into the cavity of a core box mold at high speed and evenly. After solidification, the desired shape of the sand core is obtained. Sand cores are mainly used to form the internal cavity, channel or complex structure of castings during the casting process. They are key process equipment to ensure the dimensional accuracy and internal quality of castings. However, some problems still occur in the actual use of existing sand core making machines. For example, patent application number CN202322839200.3 provides a sand-shooting head and a core-making machine. The sand-shooting head includes a sand-shooting head housing and a sand-shooting plate. The top of the sand-shooting head housing has an upwardly protruding cylinder for storing sand. The sand-shooting plate is detachably installed at the bottom of the sand-shooting head housing. The core-making machine includes the sand-shooting head and is characterized by easy cleaning of the sand head. Most existing sand-shooting head core-making machines have a simple structure and often use dual-head processing. This processing method has poor compatibility and low working efficiency during processing, thus affecting the use of the device.

[0003] To address the aforementioned problems, a dual-station single-shot core-making machine for continuous core production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a dual-station single-shot core making machine that enables continuous core making. By using this device, the problems of existing core making machines with single-shot heads, which are mostly simple in structure and often use dual heads for processing, are solved. This processing method has poor compatibility and low working efficiency during processing, thus affecting the use of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-station single-shot sand head core-making machine for continuous core making, comprising a mounting frame and a slide rail frame slidably connected inside the mounting frame. A coated sand storage tank is fixedly connected to the top of the slide rail frame. The mounting frame is provided with an adjustment mechanism, which adjusts the position of the sand head. The adjustment mechanism includes a telescopic cylinder fixedly connected to one side of the mounting frame, and the output end of the telescopic cylinder is fixedly connected to the slide rail frame.

[0006] Preferably, a telescopic cylinder three is fixedly connected inside the slide rail frame, and an upper mold is fixedly connected to the output end of the telescopic cylinder three. The upper mold is slidably connected to the bottom of the slide rail frame.

[0007] The design of the above structure allows for precise control of the lifting and lowering of the upper mold through the telescopic movement of the telescopic cylinder three, enabling rapid fitting or separation of the upper and lower molds. The sliding connection ensures stable movement trajectory of the upper mold, preventing offset from affecting mold closing accuracy and providing reliable mold closing conditions for sand injection molding.

[0008] Preferably, the mounting frame is internally fixedly connected to a fixing frame, and two sets of fixing frames are provided. A telescopic cylinder is fixedly connected to one side of the fixing frame.

[0009] With the above-mentioned structural design, the two sets of fixed frames correspond to two processing stations respectively, providing a stable installation and support foundation for the lower mold; the setting of telescopic cylinder two provides a power source for fine adjustment of the position of the lower mold, and can adjust the alignment accuracy of the lower mold and the upper mold according to the sand shooting requirements, adapting to the processing requirements of sand cores of different specifications.

[0010] Preferably, the output end of the telescopic cylinder is fixedly connected to a transmission block, the top of the transmission block is fixedly connected to a connecting frame, and the connecting frame is slidably connected inside the fixed frame.

[0011] With the above-mentioned structural design, the transmission block plays the role of force transmission, converting the linear power of the telescopic cylinder into the sliding power of the connecting frame; the sliding fit between the connecting frame and the fixed frame ensures that the lower mold moves smoothly along the preset direction during the fine adjustment process, avoiding sand core forming defects caused by positional deviation and improving the accuracy of the adjustment action.

[0012] Preferably, a mounting plate is fixedly connected inside the connecting frame, a lower mold is provided on the top of the mounting plate, and a bolt is provided through the bottom of the mounting plate.

[0013] With the above-mentioned structural design, the mounting plate provides a standardized mounting carrier for the lower mold, enabling a stable connection between the lower mold and the connecting frame; the bolts that pass through the bottom can be used to detachably fix the lower mold through threaded engagement, which not only ensures the installation stability of the lower mold during processing, but also provides a convenient operating structure for subsequent mold disassembly and maintenance.

[0014] Preferably, a locking block is fixedly connected to the bottom of the lower mold, and the locking block has a threaded groove that matches the bolt.

[0015] The design of the above structure, with the combination of the locking block and the threaded groove, forms a precise positioning and connection structure. During installation, the locking block can be quickly aligned with the corresponding position on the mounting plate to achieve the pre-positioning of the lower mold. The matching of the threaded groove and the bolt can firmly fix the lower mold on the mounting plate through the threaded locking force, preventing the mold from loosening during processing. At the same time, the mold can be separated simply by loosening the bolts during disassembly, which greatly improves the convenience of maintenance.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application achieves the effect of quickly adjusting the position of the sand-shooting head on the upper mold by setting up a telescopic cylinder, a connecting frame, and a slide rail frame, thereby improving the work efficiency of the workers and solving the problem that most existing sand-shooting head core-making machines have a simple structure and often use dual-shooting heads for processing. This processing method has poor compatibility and low work efficiency during the processing process, which affects the use of the device.

[0017] 2. This application, through the setting of bolts, mounting plates and threaded grooves, enables workers to easily remove the lower mold for maintenance, thereby improving the effectiveness of the device and solving the problem that the lower mold on existing sand-shooting core-making machines is generally fixed on the device, making it inconvenient for workers to remove it for maintenance when needed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figures 1-3 A dual-station single-shot core-making machine for continuous core making includes a mounting frame 1 and a slide rail frame 2 slidably connected inside the mounting frame 1. A coated sand storage tank 21 is fixedly connected to the top of the slide rail frame 2. The mounting frame 1 is provided with an adjustment mechanism, which adjusts the position of the sand-shooting head. The adjustment mechanism includes a telescopic cylinder 11 fixedly connected to one side of the mounting frame 1. The output end of the telescopic cylinder 11 is fixedly connected to the slide rail frame 2.

[0023] The present invention will be further described below with reference to the embodiments. Example 1:

[0024] To address the issue that most existing core-making machines using sand-shooting heads have a simple structure and often employ dual-screw operation, resulting in poor compatibility and low efficiency, thus affecting the usability of the equipment, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4 As shown, a telescopic cylinder 211 is fixedly connected inside the slide rail frame 2. An upper mold 212 is fixedly connected to the output end of the telescopic cylinder 211. The upper mold 212 is slidably connected to the bottom of the slide rail frame 2. A fixed frame 12 is fixedly connected inside the mounting frame 1. The fixed frame 12 has two sets. A telescopic cylinder 121 is fixedly connected to one side of the fixed frame 12. A transmission block 122 is fixedly connected to the output end of the telescopic cylinder 121. A connecting frame 123 is fixedly connected to the top of the transmission block 122. The connecting frame 123 is slidably connected inside the fixed frame 12. A mounting plate 124 is fixedly connected inside the connecting frame 123. A lower mold 13 is located on the top of the mounting plate 124. When in use, the workpiece to be processed can be placed at the lower mold 13. Then, the telescopic cylinder 211 located on the slide rail frame 2 can be activated. The telescopic cylinder 211 drives the upper mold 212 to move, thereby causing the upper mold 212 to... The lower mold 13 is fitted, and the sand injection head at the upper mold 212 is activated to achieve the processing effect. The operator can also activate the telescopic cylinder 121, which drives the transmission block 122 to move, thereby moving the connecting frame 123. The connecting frame 123 drives the mounting plate 124 to move, thereby fine-tuning the position of the lower mold 13. After one set of lower molds 13 is processed, the telescopic cylinder 11 located on one side of the mounting frame 1 can be activated. The telescopic cylinder 11 drives the slide rail 2 to move, which in turn drives the upper mold 212 to move to another set of lower molds 13. When the other set of lower molds 13 is processed, the previous lower mold 13 has just been heated and solidified, thus enabling mold opening and demolding operations. This achieves the effect of quickly adjusting the position of the sand injection head on the upper mold 212, thereby improving the work efficiency of the operator. Example 2:

[0025] To address the problem that the lower mold 13 on existing core-making machines is generally fixed to the device, making it inconvenient for workers to remove it for maintenance, this embodiment discloses the following technical solution, specifically as follows: Figure 4 and Figure 5 As shown, a bolt 125 is provided through the bottom of the mounting plate 124, and a locking block 131 is fixedly connected to the bottom of the lower mold 13. The locking block 131 has a threaded groove 132, which matches the bolt 125. When the lower mold 13 is damaged and needs maintenance, the bolt 125 located at the bottom of the mounting plate 124 can be rotated. The bolt 125 rotates and causes one end of the bolt 125 to come out from the inside of the threaded groove 132, so that the lower mold 13 can be removed from the mounting plate 124. When installing the lower mold 13, the locking block 131 at the bottom of the lower mold 13 is aligned with the mounting plate 124 and inserted. Finally, the bolt 125 is rotated in the opposite direction to fix the lower mold 13, thus completing the installation. This allows the staff to easily remove the lower mold 13 for maintenance, improving the efficiency of the device.
