Description

Technical Field

[0001] The utility model belongs to the technical field of step-difference molds, and particularly relates to a novel V-shaped step-difference middle mold. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In short, molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. With the development of society, the demand for metal product processing is increasing, and step-down molds are needed for production and manufacturing. Step-down molds are specially designed molds used for one-time forming of multiple sections or sections in a product. This mold design allows multiple movable or adjustable parts to be included in a mold to facilitate the formation of different parts or features of the product in a single forming process.

[0003] At present, the existing V-shaped step-difference middle die is made by machining the inner hole by wire walking, and the V-shaped step of the middle die is machined by discharge using copper male. Due to the deep depth of the middle die step and the high cost of copper male, the mold cost is high, the discharge machining time is long, and the production efficiency is low. At the same time, discharge machining is difficult, carbon deposition is easy to occur on the bottom, and there are certain safety hazards.

[0004] Therefore, a new type of V-shaped step-difference middle mold is needed to solve the problems of high processing cost and low processing efficiency of the V-shaped step-difference middle mold in the prior art. Utility Model Content

[0005] The purpose of the present invention is to provide a novel V-shaped step-difference middle mold to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new V-shaped step-difference middle mold, including an upper middle mold step, the top of the upper middle mold step is detachably connected to the lower middle mold inner hole, and positioning pins are provided inside the upper middle mold step and inside the lower middle mold inner hole.

[0007] It should be noted in the solution that the top of the upper middle mold step and the bottom of the inner hole of the lower middle mold are in contact with each other.

[0008] It is further worth mentioning that the upper middle mold step difference and the inner hole of the lower middle mold are fixed by a bolt combination.

[0009] It should be further explained that the step difference of the upper middle mold and the inner hole of the lower middle mold are both cylindrical in design.

[0010] Compared with the prior art, the novel V-shaped step-difference middle mold provided by the present invention has at least the following beneficial effects:

[0011] (1) The manufacturing process is changed by dividing the mold into the upper mold segment and the lower mold inner hole for separate processing. The original discharge processing of the mold segment is changed to the wire-cut processing of the segment slope, which saves the cost and time of discharge. After the upper mold segment and the lower mold inner hole are processed separately, they are combined together using positioning pins and bolts to form a V-shaped segment center mold. Through this structure, the V-shaped segment center mold can be processed efficiently in a split manner, which increases the service life of the mold, improves the processing efficiency, and saves the mold processing time and copper public discharge cost.

[0012] (2) By dividing the mold into the upper middle mold segment and the lower middle mold inner hole, and then using a combination of positioning pins and bolts, the precise positioning and stability of the mold during processing can be ensured. At the same time, the possibility of carbon deposition at the bottom can be reduced, which helps to improve the ventilation and sewage discharge capacity of the bottom of the mold, reduce the failure and maintenance costs caused by carbon deposition, and reduce safety hazards.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] See also Figure 1-5 The utility model provides a new type of V-shaped step-difference middle mold, including an upper middle mold step 1, the top of the upper middle mold step 1 is detachably connected to the lower middle mold inner hole 2, and positioning pins 3 are provided inside the upper middle mold step 1 and the lower middle mold inner hole 2.

[0021] Further as Figure 1 and Figure 2As shown, it is worth mentioning that the top of the upper middle mold segment 1 and the bottom of the lower middle mold inner hole 2 are in close contact with each other. The close contact design of the top and bottom ensures the precise alignment of the upper middle mold segment 1 and the lower middle mold inner hole 2 when they are assembled. This precise positioning can effectively prevent the mold from moving or offsetting slightly during operation, and maintain the stability and consistency between the mold components. When the top and bottom are in close contact, problems caused by gaps or errors in the assembly process can be reduced, and the various parts of the mold can fit more closely, which is very important for applications requiring high-precision processing and assembly, especially in micro-scale or high-precision processing. Tight top and bottom fit can It effectively reduces the internal movement and vibration of the mold during operation. This stability not only improves processing quality, but also helps to extend the service life of the mold and equipment, and reduce maintenance costs and downtime. The top and bottom fitting design enhances the stability and rigidity of the overall mold structure, which is especially important for large molds or molds used in high-pressure and high-temperature environments. It can effectively prevent mold deformation or damage caused by changes in working conditions. The tightly fitting top and bottom design helps reduce the occurrence of accidents. Operators can use mold equipment more safely because the structural stability and precision of the mold are enhanced, reducing safety risks during use.

[0022] Further as Figure 1 、 Figure 2 and Figure 5 As shown, it is worth mentioning that the upper middle mold step 1 and the lower middle mold inner hole 2 are fixed by a bolt combination, and the locating pins 3 and bolts make the mold assembly process simpler and more efficient. The operator can easily assemble the different parts of the mold together, reducing errors or problems that may occur during the assembly process and improving production efficiency. The fixed locating pin and bolt structure can effectively reduce the internal movement and vibration of the mold during operation; the locating pin 3 and bolt design makes the maintenance and replacement of parts of the mold more convenient. When maintenance or replacement of parts is required, the operator can quickly disassemble and reassemble the mold, reducing maintenance time and downtime and improving production efficiency.

[0023] According to the above working process, it can be seen that: by dividing the mold into the upper mold segment 1 and the lower mold inner hole 2 for separate processing, the manufacturing process is changed, and the original discharge processing mold segment difference is changed to the slow wire processing segment difference slope, which saves the cost and time of discharge. After the upper mold segment 1 and the lower mold inner hole 2 are processed separately, the positioning pin 3 and the bolt are used to combine them together to form a V-shaped segment difference mold. Through this structure, the V-shaped segment difference mold can be processed efficiently in a split manner, which increases the service life of the mold, improves the processing efficiency, saves the mold processing time and copper public discharge cost.

[0024] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the upper middle die segment 1 and the lower middle die inner hole 2 are both cylindrical in design. The cylindrical design is usually easier to process, especially in CNC processing, and can be completed more efficiently. In addition, cylindrical parts are also easier to assemble, reducing assembly difficulties or failures caused by insufficient processing accuracy or fit. The cylindrical design helps to ensure the precise alignment and fit of parts during assembly, especially in the fit between the upper middle die segment 1 and the lower middle die inner hole 2, to ensure the accuracy and stability of their relative positions; the cylindrical design can provide a uniform contact surface, reduce friction and wear during assembly, which is especially important for mechanical devices that are used and maintained for a long time, and can extend the service life of parts. The cylindrical design is relatively uniform, which is conducive to the stability of the overall structure. A stable structure in mechanical equipment can improve its working efficiency and safety.

[0025] This solution has the following working process: in actual use, the mold middle mold is divided into the upper middle mold segment 1 and the lower middle mold inner hole 2 and processed separately, then the upper middle mold segment 1 and the lower middle mold inner hole 2 are fitted together, and the positioning pin 3 is used to position the upper middle mold segment 1 and the lower middle mold inner hole 2, and then they are locked with bolts to combine them into a V-shaped segment middle mold.

[0026] In summary: by dividing the mold middle die into the upper middle die segment 1 and the lower middle die inner hole 2 for separate processing, the manufacturing process is changed, and the original discharge processing middle die segment is changed to the wire-cut processing segment slope, which saves the cost and time of discharge. After the upper middle die segment 1 and the lower middle die inner hole 2 are processed separately, the positioning pin 3 and the bolt are used to combine them together to form a V-shaped segment difference middle die mold. Through this structure, the V-shaped segment difference middle die mold can be processed efficiently in a split manner, thereby increasing the service life of the mold, improving the processing efficiency, saving the mold processing time and copper male discharge cost; by dividing the mold into the upper middle die segment 1 and the lower middle die inner hole 2, and then using the positioning pin 3 and the bolt combination, the precise positioning and stability of the mold during the processing can be ensured, and the possibility of carbon deposition on the bottom can be reduced, which helps to improve the ventilation and sewage discharge capacity of the bottom of the mold, reduce the failure and maintenance cost caused by carbon deposition, and reduce safety hazards.
