[0002] With the rapid development of the mold industry, the trend of mold standardization is becoming increasingly obvious.

[0039] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0040] The present application embodiment provides a method for processing a plug, referring to Figure 1 The insert processing method is used to prepare the insert as described above, comprising the following steps:

[0041] Step S10, obtaining the sheet material to be processed;

[0042] In this embodiment, it should be noted that the insert refers to an irregular mold part used to be embedded in the mold, and plays the role of fixing the template and filling the space between the templates. The processing of the insert is mostly done by wire cutting, such as Figure 2 As shown, after the shape is processed by online cutting, the insert 1 is connected to the sheet material 2 to be processed by the rib structure 3. At this time, the rib structure 3 needs to be cut off, usually at a position outside the insert adjacent to the insert, such as the position of the cutting position indicated by the dotted line 4 in the figure, so that the insert 1 is separated from the sheet material 2 to be processed. The original preset edge of the workpiece should be at the position of the preset edge of the insert indicated by the dotted line 5. After such cutting, the actual edge of the workpiece extends outward to the position of the cutting position indicated by the dotted line 4, thereby leaving ribs protruding outward on the workpiece. The protruding ribs may cause the insert to be unable to be smoothly inserted into the mold and / or removed from the mold. Therefore, at present, after the online cutting process, it is necessary to further remove the protruding ribs through a surface grinder. In the case where the mold requires a large number of inserts, such as a stamping mold, each insert needs to have its protruding ribs removed individually by a grinder, which is costly, labor-intensive, and has a low degree of automation.

[0043] As an example, the sheet material to be processed can be selected according to the size specifications, material, etc. of the insert to be processed, wherein the thickness of the sheet material to be processed can be the same as or different from the height of the insert to be processed. When the thickness of the sheet material to be processed is different from the height of the insert to be processed, the height of the insert needs to be ground to the required target height after wire cutting. When the thickness of the sheet material to be processed is the same as the height of the insert to be processed, there is no need to grind the height of the insert after wire cutting, and the time cost and labor cost of grinding the height of the insert can be further saved. Moreover, the original processing process of the insert is wire cutting, grinder grinding and other processing steps in sequence, wherein grinder grinding is used to remove the protruding ribs and grind the height of the insert. When there is no need to grind the height of the insert, the step of grinder grinding can be completely omitted in the insert processing process, which not only saves labor cost and time cost, but also simplifies the process flow, reduces equipment investment, and effectively reduces the processing cost of the insert.

[0044] As an example, a sheet to be processed can be used to process one or more inserts. In the case where a sheet to be processed is used to process multiple inserts, layout can be performed in advance, and inserts of the same height specification can be laid out on the same sheet to be processed for processing. In this way, compared with the method of grinding each insert to a high degree after online cutting, the high degree grinding of multiple inserts of the same height specification can be achieved through one grinding, which reduces the labor cost and time cost exponentially.

[0045] Optionally, the step of obtaining the sheet material to be processed includes:

[0046] Select the sheet material to be processed whose thickness is the same as the preset insert height.

[0047] As an example, the thickness of the sheet material to be processed can be determined according to the preset insert height, so that the sheet material to be processed of the corresponding thickness can be directly purchased so that the thickness of the sheet material to be processed is the same as the insert height required for processing.

[0048] Optionally, the step of obtaining the sheet material to be processed includes:

[0049] Step S11, obtaining an initial sheet material;

[0050] Step S12, processing the thickness of the initial sheet material to a preset insert height to obtain a sheet material to be processed.

[0051] As an example, when the thickness of the initial sheet material that can be obtained is inconsistent with the preset insert height, after obtaining the initial sheet material, the thickness of the initial sheet material can be processed to the preset insert height by grinding, cutting, etc. to obtain the sheet material to be processed. By advancing the insert height processing step to before wire cutting, the height processing of inserts of the same height specification can be completed in batches, thereby reducing labor costs and time costs exponentially.

[0052] Optionally, the step of processing the initial sheet material to a preset entry height to obtain the sheet material to be processed comprises:

[0053] The initial sheet material is ground to a preset insert height by a large water-grinding machine to obtain the sheet material to be processed.

[0054] As an example, when the thickness of the initial sheet material that can be obtained is inconsistent with the preset insert height, after obtaining the initial sheet material, the initial sheet material can be ground to the preset insert height through a large water grinding machine to obtain the sheet material to be processed.

[0055] Step S20, performing wire cutting processing on the sheet material to be processed to obtain an insert with rib grooves.

[0056] In this embodiment, it should be noted that wire cutting refers to a processing method that uses a moving metal wire (molybdenum wire, copper wire or alloy wire) as an electrode wire, generates high temperature to melt or vaporize the metal by pulsed electric spark discharge between the electrode wire and the workpiece, forms a slit, and then cuts out parts. For ease of explanation, this embodiment is subsequently described with the case where the conductive path of the wire cutting is parallel to the thickness direction of the sheet to be processed, but in the actual processing process, the cutting direction can be adjusted according to the structure, shape, specifications, etc. of the insert to be processed, and this embodiment does not limit this.

[0057] As an example, the sheet material to be processed is placed on a workbench, and the wire cutting device is started. The metal wire on the wire cutting device moves based on a preset cutting path to cut the sheet material to be processed. In the process of cutting the sheet material to be processed, the outer shape of the side of the insert will be trimmed first, and at least one rib structure will be left between the insert and the sheet material to be processed. The rib structure is used to fix the insert so that the side areas of the insert except the side areas connected to the rib structure can complete the wire cutting, thereby ensuring that the insert can complete the entire wire cutting process without falling off midway. After the side areas of the insert except the side areas connected to the rib structure are all wire cut, the rib structure is cut off in the preset outer surface of the insert, so that the rib position that was originally convex is recessed into the inside of the insert, and an insert with a rib position groove is obtained. Among them, the wire cutting device can be a slow wire cutting machine, a medium wire cutting machine, etc. The shape of the rib position groove can be a square depression, an arc depression or an irregular depression, which is not limited in this embodiment.

[0058] In one practicable manner, referring to Figure 3 , Figure 3 It is a top view of the insert with rib grooves described in the embodiment of the present application, wherein the thickness direction of the insert is perpendicular to the paper surface, and the insert 1 has a rib groove 11.

[0059] In one practicable manner, referring to Figure 4 , Figure 4 This is a schematic diagram of an insert having a rib position groove that is actually obtained by processing in an embodiment of the present application. The depression marked by a square in the figure is the rib position groove.

[0060] Optionally, the depth of the rib groove is 0.2-1.0 mm.

[0061] In this embodiment, the depth of the rib groove can be as small as possible based on the achievable level of the wire cutting equipment to avoid the rib groove affecting the main structure and function of the insert. Therefore, the depth of the rib groove can be 0.2-1.0mm, for example, 0.2mm, 0.5mm, 0.8mm, 1.0mm, etc.

[0062] Optionally, the step of performing wire cutting on the sheet material to be processed to obtain an insert having rib grooves includes:

[0063] Step S21, obtaining a cutting pattern corresponding to the insert having the rib position groove;

[0064] Step S22, writing a wire cutting program according to the cutting graph;

[0065] Step S23, using a wire cutting device, based on the wire cutting program, and according to the cutting path, the sheet material to be processed is subjected to wire cutting processing to obtain an insert having rib position grooves.

[0066] As an example, the position and specification of the rib groove can be determined in advance according to the shape structure of the insert to be processed, and the corresponding cutting pattern can be drawn. According to the cutting pattern, a wire cutting program can be written, and the wire cutting program can be executed through a wire cutting device to control the metal wire on the wire cutting device to move according to the cutting path, and the sheet to be processed can be processed by wire cutting. In the process of cutting the sheet to be processed, the outer shape of the side of the insert will be trimmed first, and at least one rib structure will be left between the insert and the sheet to be processed. The rib structure is used to fix the insert so that the side areas of the insert except the side areas connected to the rib structure can be wire cut, thereby ensuring that the insert can complete the entire wire cutting process without falling off midway. After the side areas of the insert except the side areas connected to the rib structure are wire cut, the rib structure is cut off in the preset outer surface of the insert, so that the ribs that were originally convex are recessed into the inside of the insert, and an insert with rib grooves is obtained. Among them, the wire cutting equipment can be a slow wire cutting machine, a medium wire cutting machine, etc.

[0067] Optionally, the wire cutting equipment is a slow wire cutting machine.

[0068] Optionally, the step of performing wire cutting on the sheet material to be processed to obtain an insert having rib grooves includes:

[0069] Step A10, performing wire cutting processing on the sheet material to be processed to obtain an initial product connected to the sheet material to be processed via a rib structure;

[0070] Step A20, cutting from the connection area between the rib structure and the initial product to the inner side of the initial product to separate the initial product from the sheet material to be processed, and forming a rib position groove on the cut surface of the initial product to obtain an insert with a rib position groove.

[0071] In this embodiment, the rib grooves may be processed by wire cutting so that the rib grooves are formed simultaneously when the rib structure is cut.

[0072] As an example, the step of synchronously forming a rib position groove when cutting the rib structure includes: placing the sheet material to be processed on a workbench, starting the wire cutting device, and moving the metal wire on the wire cutting device based on a preset cutting path to cut the sheet material to be processed. In the process of cutting the sheet material to be processed, the shape of the side of the insert will be trimmed first, and after the side areas other than the side areas connected to the rib structure are all wire-cut, an initial product connected to the sheet material to be processed through the rib structure is obtained; then, the metal wire on the wire cutting device is controlled to cut from the connection area between the rib structure and the initial product to the inside of the initial product, so that the initial product is separated from the sheet material to be processed, and a rib position groove is formed on the cutting surface of the initial product, so that the rib position originally convex is recessed into the inside of the insert, and an insert with a rib position groove is obtained. Wherein, the connection area refers to an area on the surface of the initial product within a certain range from the position where the rib structure is connected to the initial product.

[0073] In one practicable manner, referring to Figure 5 , can control the wire extension on the wire cutting equipment Figure 4 The rib structure 3 can be separated from the insert 1 by cutting along the dotted line 41 or the dotted line 42 .

[0074] Optionally, the step of performing wire cutting on the sheet material to be processed to obtain an insert having rib grooves includes:

[0075] Step B10, performing wire cutting on the sheet material to be processed to obtain an initial product having a groove structure, wherein the initial product is connected to the sheet material to be processed via the rib structure, and a connection between the rib structure and the initial product is located in the groove structure;

[0076] Step B20, cutting the rib structure in the groove space surrounded by the groove structure to obtain an insert with rib position grooves.

[0077] In this embodiment, the rib groove is processed by wire cutting in a manner of first processing the rib groove and then cutting off the rib structure in the rib groove.

[0078] As an example, the steps of first machining a rib groove and cutting off the rib structure in the rib groove include: placing the sheet material to be processed on a workbench, starting a wire cutting device, and moving the metal wire on the wire cutting device based on a preset cutting path to cut the sheet material to be processed. In the process of cutting the sheet material to be processed, the outer shape of the side of the insert will be trimmed first, and a rib groove will be cut at the connection between the rib structure and the insert, so that the connection between the rib structure and the initial product is located in the groove structure. After the wire cutting of the other side areas except the side areas connected to the rib structure is completed, an initial product having a groove structure and connected to the sheet material to be processed through the rib structure is obtained; then, the metal wire on the wire cutting device is controlled to move into the rib groove, and the rib structure is cut from any position on the rib structure located in the rib groove, so that the initial product is separated from the sheet material to be processed. Since the position of cutting the rib structure is located in the rib groove, a rib groove can be formed on the cutting surface of the initial product, so that the originally convex ribs are recessed into the inside of the insert, and an insert with a rib groove is obtained.

[0079] In one practicable manner, referring to Figure 6 , can control the wire extension on the wire cutting equipment Figure 4 The dotted line 43 in the middle cutting position is used for cutting. After the rib structure is cut off, the height of the rib protruding outward is less than the depth of the rib groove 11, so a raised rib is formed inside the insert, which will not affect the insertion or removal of the insert, so there is no need to perform the rib removal process.

[0080] In this embodiment, the insert processing method includes the following steps: obtaining a sheet material to be processed; performing a wire cutting process on the sheet material to be processed to obtain an insert with a rib position groove. In this way, by converting the rib position that originally protrudes outward after the wire cutting process into an inward groove, it can not only overcome the defect of the rib position protruding outward, but also save the process of further removing the ribs by a surface grinder after the wire cutting process, effectively saving the manpower cost and time cost of the rib removal process, and overcoming the problem that after the wire cutting process, the workpiece is cut off, and the rib position protruding outward will be left on the workpiece. Therefore, at present, after the wire cutting process, it is necessary to further remove the ribs and process the height by a surface grinder, which has a complex process and consumes a lot of manpower and time costs. The processing cost of the insert can be effectively reduced.

[0081] Furthermore, the present invention also provides an insert, which is manufactured using the insert processing method as described above.

[0082] The insert provided by the present invention solves the technical problem of high insert processing cost in the prior art. Compared with the prior art, the beneficial effects of the insert provided by the embodiment of the present invention are the same as the beneficial effects of the insert processing method provided by the above embodiment, and the other technical features of the insert are the same as the features disclosed in the above embodiment method, which will not be repeated here.
