[0001] This invention relates to the field of surface treatment technology, and in particular to a method for processing mold parts. Background Technology

[0002] Currently, consumers have extremely high requirements for the appearance quality and assembly precision of plastic products such as headphone back covers, which requires the molds used to make these plastic products to have high quality.

[0003] In an existing surface treatment process for mold parts, such as polishing, polishing tools made of materials like oilstones are used. These polishing materials are consumed in large quantities and deform according to the shape of the object being polished. In addition, the same polishing tool is used throughout the entire polishing process, making it difficult to adapt to the polishing requirements of different polishing positions, thus making it difficult to guarantee the polishing effect.

[0004] Therefore, how to improve the surface treatment effect is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] The core of this invention is to provide a method for processing mold parts, which can improve the surface treatment effect of mold parts.

[0056] In a specific embodiment of the mold parts processing method provided by the present invention, such as Figure 1 and Figure 2 As shown, the mold part includes two sliders 31.

[0057] like Figure 6 As shown, the processing method specifically includes the following steps:

[0058] S1: Control the first polishing component 1 to perform polishing operations on the preset first polishing areas on the two sliders 31, either individually or simultaneously.

[0059] The first polishing part 1 includes a graphite structure. Graphite is a hard material with advantages such as wear resistance, lubrication, corrosion resistance, good thermal conductivity, low permeability, resistance to deformation, and low removal allowance. By adding a graphite structure to the polishing part, it can be ensured that the polishing part will not change due to the shape of the mold core during the polishing process, and the polishing part is consumed slowly.

[0060] The first polishing component 1 simultaneously polishes the preset first polishing areas on the two sliders 31. This can be determined based on the size and positional relationship between the first polishing component 1 and the two sliders 31. When the first polishing component 1 is large enough and different positions on it can simultaneously contact the preset first polishing areas on the two sliders 31, simultaneous polishing can be used to improve polishing efficiency. Otherwise, the preset first polishing areas on the two sliders 31 are polished correspondingly by the different split structures in the first polishing component 1.

[0061] S2: Controls the two sliders 31 to be assembled into a single slider group 3.

[0062] In the process of assembling in S2, there may be misalignment at the joint of the two sliders 31 that does not meet the requirements of subsequent mold work. At this time, the product size / contour cannot be guaranteed by the single-piece polishing operation in S1 alone. After S2, assembly polishing is required in S3, that is, polishing the gap to eliminate the gap and make the joint smooth.

[0063] S3: Control the second polishing part 2 to perform polishing operation in the preset second polishing area at the junction of the two sliders 31, so as to eliminate the discontinuity between the two sliders 31 in the preset second polishing area.

[0064] The second polished component 2 includes a graphite structure.

[0065] S4: Perform mirror polishing on the two sliders 31 to remove the machining marks left on the two sliders 31 by the first polished part 1 and / or the second polished part 2.

[0066] In particular, the mirror polishing in S4 can further remove the indentation and processing lines on the slider 31, so as to achieve a smooth and flat surface texture on the slider 31.

[0067] In this embodiment, the slider 31 is first polished individually, and then the two sliders 31 are assembled and polished as a whole to eliminate the discontinuity. In both the individual polishing and assembly polishing steps, the tools used include graphite structures. Graphite structures are wear-resistant, which can reduce the consumption rate and reduce the risk of deformation as the object is polished. In addition, the first polishing part 1 and the second polishing part 2 are used to perform the polishing action in these two polishing steps, which can effectively improve the polishing effect. Finally, through mirror grinding, an excellent processing effect is achieved.

[0068] Furthermore, in S1: the first polishing element 1 is controlled to perform polishing operations on the preset first polishing areas on the two sliders 31, either separately or simultaneously.

[0069] This step involves polishing each individual slider 31 before the two sliders 31 are assembled, while they are placed separately in a split configuration. Specifically, a fine polishing process can be directly applied. Each slider 31 has a parting cavity, and each parting cavity includes a strip groove 311 extending from the top surface of the slider 31 to its side surface. Furthermore, at least one end of the strip groove 311 has an opening in its extending direction. For example... Figure 1 As shown, in this embodiment, both ends of the strip groove 311 have openings, which can be directly utilized for operation during polishing. Figure 1 As shown, in this embodiment, the strip groove 311 is a bent groove, generally in the shape of an L. Of course, in other embodiments, depending on actual needs, the strip groove 311 can also be a straight groove extending in a straight direction from the top surface of the slider 31 to the side surface of the slider 31.

[0070] From the perspective of the polishing range, step S1 specifically includes: controlling the first polishing component 1 to perform polishing operations on the preset first wall surface A on the parting cavity of the two sliders 31, either separately or simultaneously.

[0071] In other words, the preset first polishing area includes the preset first wall surface A. For example... Figure 3 As shown, the first wall surface A is a portion of the groove wall of the strip groove 311. Before the slider 31 is assembled, the first wall surface A of the parting cavity of the slider 31 is polished. Compared with the embodiment where the same position is polished after the slider 31 is assembled, the parting cavity of the slider 31 is not obstructed and can be directly observed, which can reduce the polishing difficulty and improve the operation efficiency.

[0072] Optionally, in this embodiment, as Figure 3 As shown, the preset first wall surface A is the portion of the wall surface of the strip groove 311 near the side of the slider 31. Based on this, the polishing operation of the preset first wall surface A specifically includes: taking the first position on the preset first wall surface A with the largest distance from the preset center line S of the strip groove 311 as a reference, controlling the first polishing component 1 to polish the second position on the preset first wall surface A with the smallest distance from the preset center line S, until the distance between the second position and the first position from the preset center line S is the same.

[0073] Among them, such as Figure 3 As shown, the preset center line S is the center line extending along the extension direction of the strip groove 311. In this embodiment, the preset center line S of the L-shaped strip groove 311 is also generally L-shaped. Figure 3 Taking the orientation shown as an example, the preset center line S extends roughly in the left-right direction near the side of the slider 31, and the preset first wall surface A is located at the right end of the strip groove 311, near the side of the slider 31.

[0074] Before polishing the slider 31 in this type of mold, at the preset first wall surface A, the first position usually protrudes towards the preset center line S relative to the second position, causing uneven undercuts, embossing and other processing textures to form in this area. Polishing this area makes the protruding part connect smoothly with the second position, which can improve the smoothness and flatness of the surface texture of the parting cavity.

[0075] Of course, in other embodiments, the preset first polishing area may also include the outer surface of the slider 31, such as a set position on the top surface of the slider 31, or other positions on the slider 31.

[0076] From the perspective of the polishing tool, in controlling its action, S1 specifically includes: controlling the first polishing element 1 to extend into the strip groove 311 through the opening of the strip groove 311, and then performing a polishing operation on the preset first wall surface A. Depending on the polishing position, the first polishing element 1 may extend into only the opening of the strip groove 311 for polishing, or it may extend into the strip groove 311 sequentially from both openings for polishing.

[0077] In addition, before step S1, the manufacturing of the polishing tool may include: bonding and fixing a graphite structure to the first polishing tool to form the first polishing part 1. This manufacturing method is relatively simple and can reduce the manufacturing cost of the first polishing part 1. Preferably, diamond paste is applied to the graphite structure in the first polishing part 1 to improve the grinding effect.

[0078] Furthermore, in S2: control the two sliders 31 to be assembled into a single slider group 3.

[0079] This step assembles the two sliders 31. In fact, the two sliders 31, as assembled slider assembly 3, are applied to the mold. In slider assembly 3, the parting cavities of the two sliders 31 are interlocked. (Reference) Figure 2 When the two sliders 31 are assembled into slider group 3, the parting cavities on the two sliders 31 are engaged to form main cavity 4. Main cavity 4 is a through hole structure that extends from the top surface of slider group 3 to the side surface of slider group 3. Main cavity 4 has a top opening 41 on the top surface of slider group 3 and a side opening 42 on the side surface of slider group 3.

[0080] Furthermore, in S3: the second polishing element 2 is controlled to perform a polishing operation in a preset second polishing area at the junction of the two sliders 31.

[0081] From the perspective of the polishing range, step S3 specifically includes: controlling the second polishing part 2 to perform polishing operation in the irregular area B at the junction of the parting cavities of the two sliders 31;

[0082] Among them, such as Figure 4As shown, a portion of the inner wall of the parting cavity protrudes into the cavity to form an irregularly shaped region B. In other words, the pre-defined second polishing area includes the irregularly shaped region B. By polishing the irregularly shaped region B, the grooves 311 of the two sliders 31 can be smoothly and seamlessly joined.

[0083] Specifically, the irregular region B can be located in the middle of the extension direction of the through-hole structure. In this embodiment, the strip groove 311 is an L-shaped groove, and correspondingly, the main cavity 4 is also an L-shaped through-hole structure, which can be adapted to the shape of the earphone. Optionally, in the main cavity 4, the part between its bending position and the top opening 41 of the main cavity 4 is a horn hole structure, and one end of the horn hole structure on the top surface is the large-diameter end; while the part from the bending position to the side opening of the main cavity 4 is a linear tail hole structure. The irregular region B is located at the bending position, which is the connection position of the horn hole structure and the tail hole structure, specifically an irregular bending surface with a general angle of 90°. Polishing is used to remove the discontinuity at the connection between the two slider parting cavities of the horn hole structure and the tail hole structure, so that the two parting cavities transition smoothly at the position of the horn hole structure and smoothly transition at the position of the tail hole structure.

[0084] In addition, from the perspective of the polishing range, step S3 may also include: controlling the second polishing part 2 to perform polishing operation on the edge area C at the junction of the parting cavities of the two sliders 31.

[0085] Among them, such as Figure 4 As shown, the edge region C is a portion of the wall surface of the strip groove 311 near the opening of the strip groove 311. Specifically, the edge region C is located on the portion of the wall surface near the side opening in the tail hole structure. That is to say, in S3, the preset second polishing area includes not only the irregular region B, but also the edge region C, so as to meet the roughness requirements of this type of mold at the bend and near the opening, respectively.

[0086] Optionally, in terms of polishing sequence, the irregular region B can be polished first, followed by the edge region C, or the edge region C can be polished first, followed by the irregular region B.

[0087] Of course, in other embodiments, the preset second polishing area may include only one of the irregular area B and the edge area C, or may also include other locations of the main cavity 4.

[0088] From the perspective of polishing tools, S3 uses a second polishing element 2 for polishing, which includes a first polishing rod 21 and a second polishing rod 22. Combined with the structural feature of the main cavity 4 having two openings, S3 specifically includes: controlling the first polishing rod 21 and the second polishing rod 22 to extend into the main cavity 4 from the top opening 41 and the side opening 42 respectively, to perform polishing operations on the irregularly shaped area B, thereby improving polishing efficiency.

[0089] Preferably, regarding the power of the polishing tool, in step S3, specifically: after connecting the second polishing element 2 to the electric grinder, the second polishing element 2 is controlled to perform polishing operations in a preset second polishing area at the junction of the two sliders 31. Electric control can improve polishing efficiency. Of course, in other embodiments, the second polishing element 2 can also be manually controlled or controlled by other power mechanisms.

[0090] Preferably, before step S3, the manufacturing of the polishing tool can be performed by: attaching a second polishing tool with a graphite structure to a connecting rod to form a second polishing part 2, and then installing the connecting rod onto an electric grinder. This polishing tool has a simple structure and is easy to manufacture. Furthermore, this manufacturing step can be performed simultaneously with any step before S3, or interspersed before or after any step. The connecting rod can be made of bamboo chopsticks for easy material access, and the graphite structure can be attached to the chopsticks using adhesives such as glue. Of course, in addition to the graphite structure, the connecting rod can also include other consumables such as felt. Furthermore, diamond paste can be applied to the graphite structure in the second polishing part 2 to improve the grinding effect.

[0091] Furthermore, in S4: the two sliders 31 are mirror-polished to remove the machining marks left on the two sliders 31 by the first polished part 1 and / or the second polished part 2. That is, after the assembly operation in S2, S3 and S4 are performed in sequence, which is equivalent to performing rough polishing and fine polishing on the assembled slider group 3 in sequence.

[0092] Specifically, S4 can be performed using the following steps:

[0093] The graphite structure for grinding is finished with sandpaper until its surface reaches the set gloss standard.

[0094] Then, the first abrasive, consisting of a graphite structure for grinding and a first type (e.g., type 3.5#) of diamond paste, is used to remove the machining marks on the two sliders 31.

[0095] Then, the second abrasive, consisting of fine-textured tin foil 51 and diamond paste of a second type (e.g., type 2.5#) with a diamond paste particle diameter smaller than the first type, is used to remove the orange peel and pitting on the two sliders 31, thereby completing the mirror polishing of the two sliders 31.

[0096] The fine-textured tin foil 51 features circular textures less than 0.005mm raised on its surface, allowing for targeted grinding of specific areas. Multiple circular textures 511 are arranged in a matrix on the surface of the fine-textured tin foil, ensuring uniform grinding performance across different areas. Additionally, as... Figure 5As shown, the fine-textured tin foil 51 can be adhered to rod-shaped structures 52 such as bamboo chopsticks to provide a point of force for the operator, facilitating operation. Using the above method to perform mirror polishing step by step ensures the polishing effect.

[0097] Of course, in other embodiments, S4 can also employ a grinding structure made of wool felt to grind appropriate positions of the slider 31, removing the texture from the surface of the slider 31 and polishing it to a mirror finish, making the surface texture of the mold smooth and flat. Specifically, in this grinding structure, glossy paper and diamond paste can be applied to the wool felt. In addition, the wool felt can be fixed to one end of a bamboo chopstick to control its position. Furthermore, depending on the grinding precision requirements, the type of diamond paste used in this step can be selected between 1.5# and 5#.

[0098] Furthermore, after S4, it may also include: S5: detecting the roughness of the mirror-polished areas on the two sliders 31.

[0099] This step can be specifically performed using CMM (Coordinating Measuring Machine) / OMM (Optical Measuring Machine) to conduct three-dimensional and CAV (Computer Aided Verification) scans, which can specifically confirm whether there are defects such as orange peel, pitting, or rough lines on the surface of slider group 3.

[0100] By checking the surface roughness after mirror polishing and determining the current roughness, the next step can be determined based on the test results. If it passes the test, the polished slider group 3 constitutes at least part of the mold structure for continued use; if it fails, it can be scrapped or the unqualified areas can be repolished.
