Description

Technical Field

[0001] This utility model relates to the field of ductile iron casting technology, and in particular to a casting mold used for ductile iron casting. Background Technology

[0002] Ductile iron, a high-strength cast iron material developed in the 1950s, boasts comprehensive properties approaching those of steel. Based on its superior performance, it has been successfully used to cast parts subject to complex stresses and requiring high strength, toughness, and wear resistance. However, the production of ductile iron parts requires mold casting. Traditionally, the upper and lower molds are manually separated and closed, which is time-consuming and labor-intensive, and makes rapid mold cooling inconvenient. Furthermore, excessively rapid cooling can sometimes negatively impact the performance of the ductile iron parts. Traditional methods also lack the flexibility to adjust cooling efficiency as needed. Therefore, this paper proposes a casting mold for ductile iron parts to address these issues. Utility Model Content

[0003] The technical problem this invention aims to solve is to address the aforementioned technical deficiencies by providing a casting mold for ductile iron parts. This structure avoids the time-consuming and laborious process of manually separating and closing the mold in traditional methods. It allows for adjustment of cooling efficiency as needed, facilitating improved processing efficiency without affecting the performance of the ductile iron parts, and making it more convenient to use.

[0004] The technical solution adopted by this utility model is as follows: A casting mold for ductile iron parts is provided, comprising an upper mold and a lower mold, characterized in that: it further comprises a water tank; a water pump is installed in the water tank; multiple spiral holes are opened in both the upper and lower molds; the lower ends of the spiral holes are connected to the upper end of the water tank through water outlet pipes; the upper ends of the upper spiral holes are connected to the upper ends of the lower spiral holes through water inlet pipes; the water inlet pipes are connected to the water outlet of the water pump through regulating pipes; valves are installed on the regulating pipes; and a control device for controlling the upper mold is also included.

[0005] To further optimize this technical solution, a control device for a casting mold used for ductile iron parts includes a base; a lower mold is mounted on the base; a bracket is mounted on one side of the base; and an upper mold is threadedly connected to the bracket via a screw.

[0006] To further optimize this technical solution, a threaded block is rotatably connected to a support for a casting mold used as a ductile iron part; a screw is threadedly connected to the threaded block; the lower end of the screw is fixedly connected to the upper end of the upper mold; the upper mold is vertically slidably connected to the support via a slide rod; a drive motor is installed on one side of the support; the output end of the drive motor controls the rotation of the threaded block through a transmission chain mechanism.

[0007] To further optimize this technical solution, a water tank and water pump used as a casting mold for ductile iron parts are mounted on a base.

[0008] To further optimize this technical solution, the water outlet pipe and regulating pipe at the upper mold of a casting mold used for ductile iron parts are both telescopic flexible hoses.

[0009] Compared with traditional casting molds for ductile iron parts, the advantages of this invention are as follows:

[0010] 1. The design of the drive motor, transmission chain mechanism, threaded block, screw, slide bar, and upper mold facilitates casting and easy removal of ductile iron parts. It avoids errors caused by manual separation and closure in traditional methods, resulting in higher precision. The motor-driven operation is also more labor-saving.

[0011] 2. The design of the upper mold, lower mold, valve, water pump, water tank, regulating pipe, water inlet pipe, spiral hole, and water outlet pipe facilitates rapid cooling of the ductile iron parts inside the mold, thereby increasing the cooling speed and processing efficiency.

[0012] The multiple valves allow for adjustment of cooling efficiency as needed, facilitating processing efficiency without affecting the performance of ductile iron parts, and making it more convenient to use.

[0013] 3. The water outlet pipe and regulating pipe at the upper mold are both telescopic hoses. When the upper mold moves up and down, the telescopic hoses can be easily extended and retracted to ensure that cooling liquid can be delivered. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3As shown, a casting mold for ductile iron parts includes an upper mold 1 and a lower mold 2, characterized in that: it further includes a water tank 3; a water pump 4 is installed in the water tank 3; both the upper mold 1 and the lower mold 2 have multiple spiral holes 5; the lower ends of the spiral holes 5 are connected to the upper end of the water tank 3 through water outlet pipes 6; the upper ends of the upper spiral holes 5 are connected to the upper ends of the lower spiral holes 5 through water inlet pipes 7; the water inlet pipes 7 are connected to the water outlet of the water pump 4 through regulating pipes 8; each regulating pipe 8 is equipped with a valve 9; it also includes a control device for controlling the upper mold 1; the control device includes a base 10; the lower mold 2 is installed... On the base 10; a bracket 11 is installed on one side of the base 10; the upper mold 1 is threadedly connected to the bracket 11 via a screw 13; a threaded block 12 is rotatably connected to the bracket 11; the screw 13 is threadedly connected to the threaded block 12; the lower end of the screw 13 is fixedly connected to the upper end of the upper mold 1; the upper mold 1 is vertically slidably connected to the bracket 11 via a slide rod 14; a drive motor 15 is installed on one side of the bracket 11; the output end of the drive motor 15 controls the rotation of the threaded block 12 through a transmission chain mechanism 16; the water tank 3 and the water pump 4 are installed on the base 10; the water outlet pipe 6 and the regulating pipe 8 at the upper mold 1 are both telescopic flexible hoses 17.

[0020] In use, by turning on the drive motor 15, the drive motor 15 controls the rotation of the threaded block 12 through the transmission chain mechanism 16. According to the threaded connection between the threaded block 12 and the screw 13, and according to the sliding limit of the upper mold 1 by the slide rod 14, when the threaded block 12 rotates, the screw 13 will drive the upper mold 1 to move vertically up and down, which facilitates the downward movement of the upper mold 1 and its cooperation with the lower mold 2 for casting. It also facilitates the removal of the cast ductile iron part after the upper mold 1 moves upward. This avoids the errors caused by manual separation and closure in the traditional process, resulting in higher precision. The motor-driven operation is also more labor-saving.

[0021] After the upper mold 1 and lower mold 2 are closed for casting, valve 9 is opened, and then water pump 4 is turned on. Water pump 4 transports the liquid in water tank 3 to regulating pipe 8. Regulating pipe 8 transports the liquid to spiral hole 5 through water inlet pipe 7. The liquid in spiral hole 5 cools the upper mold 1 and lower mold 2. Finally, the liquid returns to water tank 3 through water outlet pipe 6, which facilitates rapid cooling of upper mold 1 and lower mold 2, thereby cooling the ductile iron parts in the mold, improving the cooling speed, and improving the processing efficiency.

[0022] The presence of multiple valves 9 may sometimes cause the ductile iron parts to cool down too quickly, which could affect their performance. The cooling efficiency can be adjusted according to the situation, making it easier to improve processing efficiency without affecting the performance of the ductile iron parts, and making it more convenient to use.

[0023] The water outlet pipe 6 and the regulating pipe 8 at the upper mold 1 are both telescopic hoses 17. When the upper mold 1 moves up and down, the telescopic hoses 17 can be easily used to extend and retract, while ensuring that cooling liquid can be transported.

[0024] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0025] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
