[0024] Refer to Figure 1-2 as shown, which is a preferred embodiment provided by the present utility model.
[0025] The structure of the mold forming part includes a forming part 100. A sealing cavity is provided inside the forming part 100. A hollow tube 200 is provided in the sealing cavity. A hollow cavity 201 is provided in the hollow tube 200. A reflux interval 105 is formed between the outer periphery of the hollow tube 200 and the inner side wall of the sealing cavity. Here, the reflux interval 105 can be arranged in a full surround around the outer periphery of the hollow tube 200, or can be arranged in a set angle around it, which can be determined according to the actual situation.
[0026] The forming part 100 is provided with a liquid inlet 102 that communicates with the hollow cavity 201 and through which the coolant enters, and the forming part 100 is provided with a liquid outlet 103 that communicates with the reflux interval 105 and through which the coolant is discharged. The liquid inlet 102, the hollow cavity 201, the reflux interval 105, and the liquid outlet 103 form a one-way flow path.
[0027] In the above-provided structure of the mold forming part, during the process of the mold forming the workpiece, the temperature of the forming part 100 rises. The coolant enters the hollow cavity 201 through the liquid inlet 102 and flows from the hollow cavity 201 to the reflux interval 105. During the process of the coolant flowing along the reflux interval 105, it absorbs the heat of the forming part 100. After reducing the temperature of the forming part 100, it is discharged from the liquid outlet 103, thereby preventing the temperature of the forming part 100 from being too high and avoiding affecting the forming process of the workpiece due to the too high temperature of the forming part 100.
[0028] The formed part can be a formed part of a mold, a formed insert, a formed female die, a formed male die, etc. In some embodiments, the outer periphery of the hollow tube 200 is covered with a heat insulation structure. In this way, during the flow of the coolant in the hollow cavity 201, the heat in the return interval 105 will not be transferred to the inside of the hollow cavity 201, ensuring that after the coolant flows to the return interval 105, it can absorb heat from the formed part 100, and can make the coolant preferentially dissipate heat from the hottest position of the formed part, so as to improve the cooling effect.
[0029] In some embodiments, the heat insulation structure is a heat insulation coating or a heat insulation film coated on the outer periphery of the hollow tube 200. In this way, the structure is simple and it is convenient to arrange the heat insulation structure.
[0030] A one-way valve 302 for restricting the one-way flow of the coolant to the return interval 105 is provided in the hollow cavity 201. In this way, the coolant in the return interval 105 can be restricted from flowing back into the hollow cavity 201, ensuring the one-way flow of the coolant in the one-way flow path, and ensuring that the coolant can effectively and directly absorb heat from the formed part 100. Secondly, the heat of the formed part 100 can be prevented from flowing back into the hollow cavity 201, so that the hottest position of the formed part 100 can be preferentially dissipated heat.
[0031] In some embodiments, one end of the hollow tube 200 forms a liquid inlet section, and the liquid inlet 102 is communicated with the hollow cavity 201 through the liquid inlet section; the other end of the hollow tube 200 forms a communication section, and the hollow cavity 201 is communicated with the return interval 105 through the communication section, and the liquid inlet 102 and the liquid discharge port 103 are respectively arranged away from the communication section. In this way, the coolant can flow along the maximum length distance of the return interval 105 to realize wide-range contact heat absorption and temperature reduction of the formed part 100.
[0032] In addition, the communication section abuts against the end of the sealing cavity. The coolant coming out of the hollow cavity 201 first contacts the end of the sealing cavity and can absorb heat from the end of the formed part 100 first. Generally, the end of the formed part 100 is the part with the highest heat, so that more efficient heat absorption and temperature reduction can be realized.
[0033] In some embodiments, a return notch 202 is provided on the circumferential side of the communication section, and the hollow cavity 201 is communicated with the return interval 105 through the return notch 202. By arranging the return notch 202, the structure is simple, and a plurality of return notches 202 can be provided. The plurality of return notches 202 are arranged at intervals along the circumferential direction of the communication section. The coolant coming out of the hollow cavity 201 can flow back to the return interval 105 through the plurality of return notches 202, and the coolant can contact the formed part 100 in a circumferential shape to absorb heat and reduce the temperature.
[0034] In some embodiments, there is a liquid inlet interval 106 between the outer periphery of the liquid inlet section and the inner side wall of the sealing cavity. The liquid inlet interval 106 is arranged separately from the reflux interval 105. The liquid inlet 102 is communicated with the liquid inlet interval 106. The coolant entering through the liquid inlet 102 first enters the liquid inlet interval 106 and then enters the hollow cavity 201 from the liquid inlet interval 106, which facilitates the connection between the liquid inlet 102 and the hollow cavity 201 and also facilitates the delivery of the coolant to the hollow cavity 201.
[0035] In addition, a liquid inlet notch 203 is provided on the circumferential side of the liquid inlet section. The liquid inlet 102 is communicated with the hollow cavity 201 through the liquid inlet notch 203. According to actual needs, a plurality of liquid inlet notches 203 can be arranged, and the plurality of liquid inlet notches 203 are arranged at intervals along the outer periphery of the liquid inlet section, so that the coolant can be injected into the hollow cavity 201 in multiple directions.
[0036] In some embodiments, a sealing ring 301 is sleeved on the outer periphery of the hollow tube 200. The outer periphery of the sealing ring 301 is butted against the inner side wall of the sealing cavity. The sealing ring 301 separates the liquid inlet interval 106 from the reflux interval 105. The structure is simple and the sealing performance is good.
[0037] A counterbore 104 is further provided at the end of the molded part 100. The counterbore 104 is communicated with the sealing cavity, which facilitates the placement of the hollow tube 200 into the sealing cavity through the counterbore 104. A sealing block 300 is arranged in the counterbore 104. The sealing block 300 abuts against the hollow tube 200 to fix the hollow tube 200 firmly in the sealing cavity, and the sealing block 300 seals the counterbore 104. The sealing block 300 and the sealing ring 301 seal the end of the liquid inlet interval 106, so as to separate the liquid inlet interval 106 from the reflux interval 105 and also from the end of the molded part 100, and it is only communicated with the liquid inlet 102.
[0038] In some embodiments, the molded part 100 is arranged in a column shape, the sealing cavity extends in a column shape along the axial direction of the molded part 100, and the hollow tube 200 extends in a column shape along the axial direction of the molded part 100. In this way, the reflux interval 105 can extend along the axial direction of the molded part 100. During the flow of the coolant in the reflux interval 105, a wide range of contact heat absorption and temperature reduction of the molded part 100 can be achieved.
[0039] In some embodiments, a head plane part 101 is formed on the molded part 100, and the liquid inlet 102 and the liquid discharge port 103 are respectively formed on the plane part 101. In this way, it is convenient for the processing of the liquid inlet 102 and the liquid discharge port 103.
[0040] In this embodiment, a processing device is further provided, which includes the above-mentioned mold forming part structure. In the mold forming part structure, by utilizing the unidirectional flow of the coolant, most of the heat of the formed part 100 can be absorbed and carried away, thereby preventing the temperature of the formed part 100 from being too high, and ensuring that the processing device can form high-quality workpieces, such as stretch processing and so on.
[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
