Description

Technical Field

[0001] This invention belongs to the field of mold parts processing technology, specifically relating to a curved surface forming mold for daily necessities. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. In the mold processing industry, curved surface molds are a type of mold used to manufacture curved workpieces.

[0003] A Chinese patent application discloses a method and mold for integral forming of irregularly shaped curved thin-walled titanium alloy parts. The purpose is to overcome the shortcomings of existing technologies, such as limited part shapes or high processing steps and costs, and to effectively ensure the precision forming of irregularly shaped thin-walled components. The method includes the following steps: determining the parting surface; blanking; pre-forming: bending the sheet metal from a flat state into an arc using a bending die or bending machine; welding; thermoforming: at room temperature, placing a thermoforming mold inside the welded part, using the mold's own weight to support the part and heating it in a thermoforming machine; when the part is heated to a softened state, a press applies pressure to the thermoforming mold to bring the part to the required dimensions. This method comprehensively utilizes the advantages of various processes, requiring only two welds to obtain large-sized irregularly shaped curved thin-walled titanium alloy parts with high surface quality.

[0004] In the mold processing industry, for curved mold parts, positional errors during processing can cause joint marks after the mold is processed, resulting in unsightly products. In mild cases, washing and processing are required, while in severe cases, the mold is scrapped, affecting production quality and wasting materials. To address this, we propose a curved surface forming mold for daily necessities. Summary of the Invention

[0053] Example

[0054] Please see Figures 1-9 The technical solution provided in this embodiment is as follows:

[0055] A curved surface forming mold for daily necessities includes a main body 1, a processing table 2, a positioning table 3, a frustum 5, a five-axis machining component 28, a horizontal adjustment mechanism, and a vertical adjustment mechanism. The main body 1 has a processing chamber 101 and a tool changer 102 inside. The processing table 2 is located inside the processing chamber 101. The positioning table 3 is rotatably mounted on the upper end of the processing table 2, and a positioning plate 4 is fixedly connected to its upper end. The frustum 5 is detachably connected to the upper end of the positioning plate 4, has a positioning groove 501 at its lower end, and a main mold is detachably connected to its upper end. 6. The top of the main mold 6 is provided with an upper connecting groove 601, and the auxiliary mold 7 is detachably connected in the upper connecting groove 601; the five-axis machining part 28 is set on the lower inner wall of the machining chamber 101, and its output end is detachably connected to a cutting tool 29, which is used to machine the surfaces of the main mold 6 and the auxiliary mold 7; the horizontal adjustment mechanism is set on the machining table 2, which is used to drive the positioning table 3 to rotate horizontally to adjust the horizontal machining surface; the longitudinal adjustment mechanism is set on both sides of the machining table 2, which is used to drive the positioning table 3 to rotate longitudinally to adjust the longitudinal machining surface.

[0056] In a specific embodiment of the present invention, the upper side of the positioning platform 3 is uneven, the frustum 5 is used to install and fix the main mold 6, the cutting tool 29 is located on the upper side of the main mold 6, the limiting ring 11 is located on the lower side of the processing table 2, and the positioning platform 3 is located on the upper side of the processing table 2. The limiting ring 11, the positioning platform 3, the frustum 5 and the main mold 6 are connected by the support shaft 8. The output end of the first motor 9 drives the support shaft 8 to rotate, and the support shaft 8 drives the limiting ring 11, the positioning platform 3, the frustum 5 and the main mold 6 to rotate synchronously, thereby adjusting the main mold 6 horizontally. The auxiliary mold 7 is threaded to the upper end of the shaft top post 10, and the auxiliary mold 7 is inserted into the upper groove 601 from top to bottom. Then the auxiliary mold 7 is tightened to fix the auxiliary mold 7 to the upper end of the shaft top post 10, so that the auxiliary mold 7 and the shaft top post 10 form a whole, and the surface of the auxiliary mold 7 is in contact with the upper side of the main mold 6. After assembly, the auxiliary mold The main mold 6 and the auxiliary mold 7 form a whole. At this time, the main mold 6 and the auxiliary mold 7 are machined by the cutting tool 29, so that the main mold 6 and the auxiliary mold 7 are processed at the same time. This effectively solves the problem of joint marks after the existing mold is processed, making the product more beautiful after production and improving the quality of mold processing. Moreover, when machining the curved surface, only one surface of the main mold 6 and the auxiliary mold 7 needs to be machined. Then, the first motor 9 drives the rotary table 5 to rotate, so that the surface to be machined of the main mold 6 and the auxiliary mold 7 rotates continuously. The processing process is reasonable. At the same time, when the side of the main mold 6 needs to be machined, the output end of the second motor 22 drives the worm gear 23 to rotate. The worm gear 23 drives the worm wheel 21 to rotate slowly, which in turn drives the processing table 2 to rotate longitudinally. The angle of the main mold 6 and the auxiliary mold 7 can be adjusted longitudinally, so that the side of the main mold 6 can be machined. The processing range is wider and the operation is more convenient.

[0057] Specifically, the horizontal adjustment includes a first motor 9, a support shaft 8, a shaft top post 10, and a limiting ring 11. The first motor 9 is fixedly connected to the bottom of the processing table 2. One end of the support shaft 8 is fixedly connected to the output end of the first motor 9. Its upper half has a shaped section 801, and its lower half has two through holes 802. The shaped section 801 passes through the positioning groove 501 and is inserted into the main mold 6. The shaft top post 10 is inserted from top to bottom into the upper receiving groove 601 and is fixedly connected to the upper end of the shaped section 801. The secondary mold 7 is fixedly connected to the upper end of the shaft top post 10. The limiting ring 11 is located on the lower side of the processing table 2 and is detachably connected to the support shaft 9. The circumferential surface of shaft 8; preferably, the circumferential surface of positioning platform 3 is provided with a first positioning hole 301, and a positioning rod 302 is provided in the first positioning hole 301. The positioning rod 302 passes through the first positioning hole 301 and the through hole 802 located on the upper side and extends to both ends. Both ends of the rod are threaded with nuts. The circumferential surface of limiting ring 11 is provided with a second positioning hole 1101, and a second positioning rod 1102 is provided in the second positioning hole 1101. The second positioning rod 1102 passes through the second positioning hole 1101 and the through hole 802 located on the lower side and extends to both ends. Both ends of the second positioning rod 1102 are threaded with nuts.

Figure 5 and Figure 6 As shown, the connection points of the limiting ring 11 and the positioning table 3 with the processing table 2 are both embedded in the processing table 2. During assembly, the limiting ring 11 and the positioning table 3 are both sleeved on the circumferential surface of the support shaft 8. Then, the positioning rod 302 passes through the first positioning hole 301 and one of the through holes 802, and the second positioning rod 1102 passes through the second positioning hole 1101 and the other through hole 802. After tightening the nut, the positioning table 3 is fixed to the circumferential surface of the support shaft 8 under the restriction of the positioning rod 302, and the limiting ring 11 is fixed to the circumferential surface of the support shaft 8 under the restriction of the second positioning rod 1102. The portions of the limiting ring 11 and the positioning table 3 embedded in the processing table 2 are both cylindrical, making the first The output end of motor 9 drives the support shaft 8 to rotate. The support shaft 8 can simultaneously drive the limit ring 11 and the positioning table 3 to rotate without affecting the processing table 2. The irregular part 801 has an irregular structure. After being inserted into the positioning groove 501 and the main mold 6, the frustum 5 and the main mold 6 can rotate with the support shaft 8. The secondary mold 7 is fixed on the upper end of the shaft top column 10. The shaft top column 10 rotates with the support shaft 8, thereby causing the secondary mold 7, the main mold 6 and the frustum 5 to rotate synchronously. The structure is reasonably assembled. When disassembling, the secondary mold 7 is first separated from the shaft top column 10, and then the shaft top column 10 is separated from the support shaft 8. The main mold 6 and the secondary mold 7 can then be taken out. The disassembly method is simple and facilitates the processing of the next mold.

The processing table 2 is fixed between the two horizontal shafts 13, and the processing table 2 follows the horizontal shaft 13 to rotate longitudinally, thereby adjusting the longitudinal processing angle, which is more convenient for the operator to use. There are two slides 19, and the two horizontal shafts 13 have the same center. Compared with single-axis rotation, dual-axis rotation is more stable and effectively extends the service life.

[0061] Specifically, there are installation areas 103 on both sides of the machining chamber 101. Tracks 20 are fixedly connected in both installation areas 103. Two slides 19 are slidably connected to the upper side of the track 20. An electric push rod 27 is fixedly connected in the tool change chamber 102.

Two shaft holes 502 are provided on the circumferential surface of the frustum 5. Each clip 18 is inserted into the adjacent shaft hole 502.

[0064] In specific embodiments of the present invention, such as Figure 5 and Figure 7 As shown, when installing the frustum 5, first place the frustum 5 on the upper side of the positioning plate 4, then tighten the two locking screws 17, and the two rectangular blocks 14 move closer to each other, so that the two locking pins 18 move towards the frustum 5. Finally, the two locking pins 18 are engaged in the two shaft holes 502.

The screw conveyor 31 rotates under the drive of the third motor 30, which can transport the waste and water, automatically clean up the waste, and reduce manual operation.

[0067] Specifically, a protective shell 12 is fixedly connected to the lower end of the processing table 2, and the first motor 9 is located inside the protective shell 12.

[0069] The working principle or process of the curved surface forming mold for daily necessities provided by this invention is as follows: The output end of the first motor 9 drives the support shaft 8 to rotate, and the support shaft 8 drives the limiting ring 11, the positioning table 3, the frustum 5 and the main mold 6 to rotate synchronously, thereby adjusting the main mold 6 horizontally. The auxiliary mold 7 is threadedly connected to the upper end of the shaft top column 10, and the auxiliary mold 7 is inserted into the upper groove 601 from top to bottom. Then, the auxiliary mold 7 is tightened to fix the auxiliary mold 7 to the upper end of the shaft top column 10, so that the auxiliary mold 7 and the shaft top column 10 form a whole, and the surface of the auxiliary mold 7 is in contact with the upper side of the main mold 6. After assembly, the auxiliary mold 7 and the main mold 6 form a whole. At this time, the main mold 6 and the auxiliary mold 7 are machined by the cutting tool 29. This design allows for simultaneous processing of the main mold 6 and the auxiliary mold 7, effectively solving the problem of joint marks after existing mold processing. This results in a more aesthetically pleasing product and improves mold processing quality. Furthermore, for curved surface processing, only one surface of the main mold 6 and the auxiliary mold 7 needs to be processed. The first motor 9 drives the rotary table 5 to rotate, causing the surfaces of the main mold 6 and the auxiliary mold 7 to rotate continuously. This streamlined processing process is efficient. Simultaneously, when the side of the main mold 6 needs processing, the output of the second motor 22 drives the worm gear 23 to rotate. The worm gear 23 then drives the worm wheel 21 to rotate slowly, which in turn drives the processing table 2 to rotate longitudinally. This allows for longitudinal adjustment of the angles of the main mold 6 and the auxiliary mold 7, enabling processing of the side of the main mold 6. This provides a wider processing range and more convenient operation.
