Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing and processing technology, specifically relating to a circulating casting device for automotive parts processing. Background Technology

[0002] In the automotive industry, parts casting is an essential and critical process. Generally, a metal film is used to pour molten metal into a mold cavity to obtain parts of various shapes and sizes. As the application fields of metal castings become wider and wider, the quantity and precision requirements of their production and processing are becoming higher and higher. Therefore, it is necessary to design a circulating casting device for automotive parts processing.

[0003] Traditional automotive parts casting equipment mostly adopts a single-mold intermittent operation mode in practical applications. After completing one casting, it is necessary to wait for the mold to cool and be demolded before the next round of operation can be carried out. This results in a long production cycle for individual parts. This intermittent operation makes the equipment utilization rate low and it is difficult to meet the ever-increasing production demand of the automotive industry. In addition, external mold opening tools are required during the mold opening process, which increases the inconvenience and cumbersomeness of the subsequent mold opening for operators. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed circulating casting device for processing automotive parts in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A circulating casting device for processing automotive parts includes a base, characterized in that a protective component is fixedly installed at the top edge of the base, a circulating component is rotatably installed on the top of the base and placed inside the protective component, a mold component is slidably passed through the top of the circulating component and placed inside the protective component, and an arc-shaped push block is fixedly installed on the top of the base and placed below the circulating component and cooperating with the mold component.

[0007] As a further optimization of this utility model, the protective component includes a protective shell fixedly installed at the top edge of the base. Both ends of one side of the protective shell are fixedly installed with semiconductor cooling chips.

An internal gear ring is fixedly mounted on the inner side of the mounting ring. A servo motor is fixedly mounted on one side at the middle position of the top of the base. A gear located inside the mounting ring and meshing with the internal gear ring is fixedly mounted on the output end of the top of the servo motor.

[0009] As a further optimization of this utility model, the mold assembly includes multiple lower molds fixedly installed on the top of the mounting ring. Multiple upper molds are placed on the top of the multiple lower molds and placed on the top of the inner side of the protective shell. The top of the multiple upper molds is provided with a casting port that communicates with the inside of the casting guide port and the inside of the lower molds. Limiting rods that slide through to the outside of the mounting ring are fixedly installed at the four corners of the bottom of the multiple upper molds. Springs are fitted and fixed to the bottom of the outer side of the multiple limiting rods.

[0010] As a further optimization of this utility model, the arc-shaped push block is fixedly installed on one side of the top edge of the base and placed below the limiting rod. One side of the arc-shaped push block is provided with a guide slope that cooperates with multiple limiting rods.

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 , Figure 2 , Figure 4As shown, a circulating casting device for processing automotive parts includes a base 1, which serves as the mounting base. The base 1 is made of high-strength cast iron, and its surface is subjected to aging treatment to eliminate internal stress. A protective shell 200 is fixedly installed at the top edge of the base 1 by bolts. The protective shell 200 has a circular structure, and a circular sealing plate is fixedly installed on the top. A notch is opened on one side of the protective shell 200 and the sealing plate to facilitate the installation, removal, and observation of parts later, and to prevent heat dissipation during the casting process. Semiconductor cooling chips 203 are symmetrically fixedly installed at both ends of one side of the protective shell 200. The cooling surface of the semiconductor cooling chip 203 faces the inside of the device, which can facilitate targeted cooling of the mold after casting and accelerate the cooling and forming of the casting. An opening groove 201 is opened at one end of the back side of the top side of the protective shell 200. A casting guide port 202 is fixedly installed on the top of the opening groove 201 by a flange. The casting guide port 202 has a funnel-shaped structure, and its bottom is connected to the opening groove 201 to guide the molten metal into the mold.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, to achieve the cyclic conveying of the mold, a mounting ring 302 is horizontally rotated above the top of the base 1. The mounting ring 302 is a ring-shaped steel structure located inside the protective shell 200. An annular groove is provided on the outside of the mounting ring 302. A sliding ring extending to the outside of the annular groove is slidably provided inside the annular groove. Multiple support rods are evenly fixedly installed on the outside of the sliding ring. The bottom of the support rods is fixedly connected to the top of the base 1. Through the cooperation of the sliding ring and the annular groove, the mounting ring 302 is ensured to rotate stably. An internal gear ring 300 is fixedly installed on the inner side of the mounting ring 302 by bolts. A servo motor 303 is fixedly installed on one side at the middle position of the top of the base 1. The servo motor 303 is a Siemens 1FT7. A gear 301 is fixedly installed on the top output end of the servo motor 303 through a coupling. The gear 301 is placed inside the mounting ring 302 and meshes with the internal gear ring 300. When the servo motor 303 works, the mounting ring 302 is driven to rotate smoothly through the transmission of the gear 301 and the internal gear ring 300.

[0026] like Figure 2 , Figure 3As shown, to achieve the core work of casting, lower molds 401 are evenly distributed and fixed to the top of the mounting ring 302 with bolts. These lower molds 401 can rotate synchronously with the mounting ring 302. An upper mold 400 is placed on top of each lower mold 401, and the upper mold 400 cooperates with the lower mold 401. The upper part of the upper mold 400 is placed inside the top of the protective shell 200, forming a sliding fit with the protective shell 200. Each upper mold 400 has a pouring port 404 on its top. When the upper mold 400 and the lower mold 401 rotate to a specific position simultaneously, casting begins. The inlet 404 is connected to the interior of the casting guide inlet 202 and the interior of the lower mold 401, forming a molten metal injection channel. Limiting rods 402 are vertically fixed at the four corners of the bottom of the upper mold 400. The limiting rods 402 slide through to the outside of the mounting ring 302 to guide the mold closing and opening process of the upper and lower molds. Springs 403 are fitted and fixed to the bottom of the outer side of the limiting rods 402. The top of the springs 403 abuts against the bottom of the mounting ring 302, and the bottom abuts against the limiting block at the bottom of the limiting rods 402, providing upward elastic support for the upper mold 400.

[0027] like Figure 2 , Figure 5 , Figure 6 As shown, to achieve mold opening and closing control, the arc-shaped push block 5 is fixedly installed on one side of the top edge of the base 1 by bolts, located below the limit rod 402. A guide slope is provided on one side of the arc-shaped push block 5. The guide slope cooperates with multiple limit rods 402. When the mounting ring 302 drives the upper mold 400 and the lower mold 401 to rotate, the bottom of the limit rod 402 will contact the guide slope of the arc-shaped push block 5. As the rotation process proceeds, the limit rod 402 moves upward along the guide slope, driving the upper mold 400 to move upward to open the mold. When the limit rod 402 disengages from the arc-shaped push block 5, it resets under the action of the spring 403, driving the upper mold 400 to move downward to close the mold. When the mold is opened, it is convenient for the operator to pick up the casting, thus realizing the cyclic pouring operation of the device.

[0028] It should be noted that, in the operation of this circulating casting device for automotive parts processing, the operator can first move the base 1 and above to the designated position and connect the power supply. Then, the servo motor 303 is started, which drives the mounting ring 302 to rotate through the gear 301 and the internal gear ring 300. This causes the lower mold 401 to move synchronously with the mounting ring 302. When a set of molds moves to below the casting guide port 202, the casting port 404 is aligned with the casting guide port 202. The molten metal is injected into the mold cavity through the casting guide port 202 and the casting port 404. The mold continues to rotate and, after leaving the casting position, the semiconductor cooling chip 2... 03. Cool the mold. When the mold rotates to the part removal position, the limit rod 402 contacts the arc-shaped push block 5, which drives the upper mold 400 to rise and the lower mold 401 to open, completing the placement and removal of the casting. The limit rod 402 disengages from the arc-shaped push block 5, and the upper mold 400 descends and closes under the action of the spring 403. Then, as the mounting ring 302 continues to rotate, it drives the lower mold 401 and the upper mold 400 to be placed at the pouring position, thereby realizing the cyclic pouring function. At the same time, the servo motor 303 controls the start and stop operations of the entire pouring process. The whole process realizes the continuous cyclic pouring of automotive parts, which greatly improves production efficiency.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
