Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, and in particular to a method for producing a silicone bag mold and the mold itself. Background Technology

[0002] In existing mold production, the mold is usually cast first according to the required shape, and then the semi-finished mold is ground and polished to form the corresponding mold, which can then be used in mold production. This method of mold production has the advantages of simple production and low production cost. However, in order to meet different needs, many molds with complex structures have been produced. For example, the blank of a toothed mold has multiple arc protrusions spaced apart from one side to the other. Between two adjacent arc protrusions, there is an inner arc recess on the blank. When grinding this mold, the grinding tool must pass between the two protrusions to grind the inner arc-shaped recess on the blank. Because the diameter of the concave opening at the top of the concave is smaller than the diameter of the concave, and there are protrusions on both sides restricting it, the grinding head cannot enter the concave and cannot perform the inner arc grinding operation on the concave teeth, thus affecting the mold production. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a method for manufacturing silicone bag molds. The method involves processing a mold blank using machining equipment to manufacture a connecting component module for the silicone bag mold. The connecting component module is an annular body located on the upper part of the silicone bag mold, with its top and bottom surfaces forming arcs. The module contains a connecting channel penetrating the first and last sides. The top and bottom surfaces are respectively formed by concave areas of the same arc degree, creating a top concave area and a bottom concave area. The first and last sides of the top and bottom concave areas are connected to the outside, and the two ends of the last side are also connected to the outside, forming protruding limiting strips. Multiple arc-shaped recesses are recessed along the direction of the limiting strips in the top and bottom concave areas, with intervals between the recesses forming... Each of the interval portions is provided with convex teeth that match the shape of the concave teeth. The outer surfaces of the concave and convex teeth are connected to the inner surfaces of the corresponding limiting strips. The top concave area and the bottom concave area are respectively provided with a first groove and a second groove. The first groove has a first convex strip and a second convex strip protruding from the surface of the top concave area on both sides of the groove opening. The bottom of the second groove has a third convex strip that can protrude from the groove opening. The first groove, the second groove, the first convex strip, the second convex strip, and the third convex strip are all arranged at intervals along the arrangement direction of the limiting strips and the outer sides of the corresponding convex and concave teeth. The processing equipment includes a mounting base for fixing the mold blank and a switching mechanism for changing the 3D printer head and the grinding head. The production method specifically includes the following steps:

[0004] S1, after the mold blank is fixed on the mounting base, the grinding head mounted on the switching mechanism is controlled to move with the switching mechanism for the first processing. The grinding head can grind the mold blank to form a top concave area, a bottom concave area and a connecting channel.

[0005] S2, after the first processing movement of the switching mechanism is in place, the grinding part is controlled to move for the second processing movement with the switching mechanism. The grinding head can grind multiple concave teeth and a first groove placed on the top concave area, and multiple concave teeth and a second groove placed on the bottom concave part on the mold blank.

[0006] S3, after the second processing movement of the switching mechanism is in place, control the switching mechanism to change the grinding head to the 3D printer head. After the switching mechanism completes the switching of the 3D printer head, control the 3D printer head to perform the third processing movement with the switching mechanism to print and form multiple protruding teeth placed on the top surface of each interval in the top concave area and the top surface of each interval in the bottom concave area.

[0007] S4, after the third processing movement of the switching mechanism is in place, control the 3D printer head to perform a fourth processing movement with the switching mechanism to print and form the first and second convex strips placed on the top concave area, and the third convex strip placed on the bottom concave area.

[0008] Preferably, step S3 specifically includes:

[0009] S31, When the switching mechanism completes the switching of the 3D printer head, control the switching mechanism to move the 3D printer head to the preparation point above the mold blank. When the 3D printer head moves to the preparation point, control the mounting base to adjust the mold blank to the first preparation state with the top concave area facing upward.

[0010] S32, When the mold blank is in the first preparation state, control the 3D printer head to move to the top surface of each interval in the top recess and bottom recess in sequence by following the switching mechanism to perform the third processing movement. When the 3D printer head moves to the top surface of the interval, control the 3D printer head to complete the printing of the corresponding convex teeth on the top surface of the interval according to the convex tooth shape.

[0011] S33, when the switching mechanism completes the third processing movement, the control switching mechanism changes the 3D printer head to the grinding head. When the grinding head switching is completed, the control switching mechanism drives the grinding head to the preparation point. The mounting base can adjust the mold blank to the first preparation state after the grinding head reaches the preparation point.

[0012] S34, when the mold blank is in the first preparation state, control the 3D printer head to move around the outer wall of each tooth in sequence with the movement of the switching mechanism and complete the polishing of the tooth.

[0013] Preferably, the convex tooth includes a lower half of the convex tooth and an upper half of the convex tooth connected to the top surface of the lower half of the convex tooth, and the bottom surface of the lower half of the convex tooth is connected to the top surface of the corresponding spacer portion. Step 32 specifically includes:

[0014] S321, When the mold blank is in the first preparation state, control the 3D printer head to move the discharge port to the printing point on the top surface of the interval near the concave side.

[0015] S322, When the discharge port is placed at the printing point, control the discharge port to discharge material and simultaneously control the discharge port of the 3D printer head to move layer by layer to print the top surface of the interval according to the shape of the lower half of the protrusion. The discharge port can complete the printing of the lower half of the protrusion as the 3D printer head moves.

[0016] S323, When the discharge port moves with the 3D printer head after printing, stop the discharge port and simultaneously control the discharge port to move with the 3D printer head to the printing point on the top surface of the next interval.

[0017] S324, when the discharge port reaches the printing point on the top surface of the next interval section with the 3D printer head, repeat steps S322-S323 and sequentially complete the printing operation of the lower half of the protruding teeth placed on the top and bottom recessed areas.

[0018] Preferably, step S34 specifically includes:

[0019] S341, When the mold blank is in the first ready state, start the grinding head to rotate and at the same time control the grinding head to move to the polishing point on the outer wall of the lower half of the tooth near the top concave area.

[0020] S342, When the actuating head moves to the polishing point with the grinding head, the actuating head can move along the outer wall of the lower half of the tooth layer by layer with the grinding head and complete the polishing operation of the lower half of the tooth.

[0021] S343, after the actuating head finishes polishing the outer wall of the lower half of the protrusion, the actuating head is controlled to move to the polishing point on the outer wall of the lower half of the next protrusion and steps S342-S343 are repeated to complete the polishing operation of the lower half of each protrusion in sequence. After the actuating head finishes polishing the lower half of each protrusion, the rotation of the actuating head is stopped.

[0022] Preferably, step 4 specifically includes:

[0023] S41, After the grinding head finishes polishing each tooth, the control switching mechanism changes the grinding head to the 3D printer head. When the 3D printer head is switched, the control switching mechanism moves the 3D printer head to the preparation point. The mounting base can adjust the mold blank to the first preparation state when the 3D printer head moves to the preparation point.

[0024] S42, When the mold blank is adjusted to the first ready state, control the 3D printer head to move to the top concave area and complete the printing of the first convex strip and the second convex strip. The two sides of the opening of the first groove can be repeatedly moved between one side and the other side of the top concave area through the 3D printer head to complete the layer-by-layer printing of the first convex strip and the second convex strip.

[0025] S43, after the 3D printer head's ejector has completed the layer-by-layer printing of the first and second protrusions, the 3D printer head returns to the preparation point. When the 3D printer head reaches the preparation point, the mold blank is adjusted to the second preparation state with the concave surface facing upwards. When the mold blank is adjusted to the second preparation state, the ejector moves with the 3D printer head to the inner bottom wall of the second groove and completes the printing of the third protrusion. The third protrusion on the inner bottom wall can be repeatedly moved between one side and the other side of the concave area by the ejector through the ejector to complete the layer-by-layer printing of the third protrusion.

[0026] S44, after the 3D printer head's output port completes the layer-by-layer printing of the third convex strip, the control switching mechanism changes the 3D printer head to the grinding head and sequentially polishes the first, second, and third convex strips.

[0027] Preferably, step S2 specifically includes:

[0028] S21, After the grinding head completes the polishing operation on the bottom concave area, the control switching mechanism drives the grinding head to move to the preparation point. The mounting base can control the mounting base to adjust the mold blank to the first preparation state after the grinding head moves to the preparation point. When the mold blank is adjusted to the first preparation state, the control action head moves with the grinding head from one side of the top concave area to the other side to grind and form multiple concave teeth in sequence. After the action head completes the grinding of each concave tooth, the control action head moves back and forth between the other side of the top concave area and one side of the top concave area with the grinding head and grinds to form the first groove.

[0029] S22, after the actuating head completes the grinding of the first groove with the movement of the grinding cutter, the control switching mechanism drives the grinding cutter to the preparation position. The mounting base can control the mold blank to adjust to the second preparation state after the grinding cutter moves to the preparation position. When the mold blank is adjusted to the second preparation state, the control actuating head moves with the grinding cutter from one side of the bottom concave area to the other side and grinds in sequence at intervals to form multiple concave teeth. After the actuating head completes the grinding of each concave tooth, the control actuating head moves back and forth between the other side of the bottom concave area and one side of the bottom concave area with the grinding cutter and grinds to form the second groove. The actuating head can turn off the grinding rotation after completing the grinding operation of the second groove.

[0030] Preferably, step S3 specifically includes:

[0031] After the actuating head completes the polishing operation on the lower half of the protrusion with the grinding head, the control switching mechanism switches the grinding head to the 3D printer head. When the 3D printer head is switched, the discharge port is moved to the top surface of the lower half of the protrusion, and the actuating head can repeat the printing steps of the lower half of the protrusion and complete the printing operation of the upper half of each protrusion according to the shape of the upper half of the protrusion. After the upper half of each protrusion is printed, the control switching mechanism switches the 3D printer head to the grinding head. After the grinding head is installed, the actuating head can repeat the polishing operation on the lower half of the protrusion and complete the polishing operation of the upper half of each protrusion according to the shape of the upper half of the protrusion.

[0032] Preferably, step S3 specifically includes:

[0033] When the 3D printer head is installed, the discharge port of the 3D printer head is heated to the set temperature. When the 3D printer head or grinding head moves with the switching mechanism, the mounting base of the mold blank can cooperate with the movement of the 3D printer head or grinding head during the movement of the 3D printer head or grinding head. The fixing parts and bag body parts are formed by casting and then grinding and polishing. The silicone bag mold can be produced by connecting the fixing parts, connecting component modules and bag body parts.

[0034] The present invention also discloses a mold, including a silicone bag mold and a connecting component module placed on the silicone bag mold by processing a mold blank as described above. The silicone bag mold includes an upper mold, a lower mold and multiple molding components. The bottom of the upper mold can close with the top of the lower mold to form multiple storage cavities for accommodating the multiple molding components. The outer wall of the molding component can together with the inner wall of the storage cavity to form a molding space for forming a silicone bag.

[0035] Preferably, the forming component includes a fixing member, a bag body, and a connecting component module installed between the fixing member and the bag body. The tail end of the fixing member has a protrusion for the connecting component module to be fitted onto. The end of the protrusion away from the fixing member can be placed inside the head end of the bag body. The head end of the connecting component module is connected to the tail end of the fixing member, and the tail end is connected to the head end of the bag body.

[0036] This invention discloses a method for producing a mold and the mold itself. The mold blank can be formed by a combination of 3D printing and grinding. Compared to the traditional method of casting the protruding and concave teeth first and then grinding and polishing, grinding and polishing the concave teeth first facilitates their formation. During the grinding of the concave teeth, the absence of protruding teeth on both sides increases the movement space of the grinding head. The mold blank, driven by the mounting base, moves in conjunction with the grinding head, increasing the angle change of the grinding head during grinding. This facilitates grinding and polishing the inner arc of the concave teeth through the opening at the top, improving the grinding precision. After the grinding head finishes grinding and polishing each concave tooth, the mold blank can be printed with each convex tooth by the 3D printer head. This helps to ensure the integrity of the additional parts that need to be added to the mold blank after grinding and polishing the concave teeth, thereby completing the production of the mold blank into a connecting component module and completing the production of the silicone bag mold.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0053] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms “first,” “second,” and similar terms used in the specification and claims of this patent application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an” or “a” and similar terms do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0054] In this embodiment, as Figure 1 As shown, a mold is disclosed, comprising a silicone bag mold 2 and a connecting component module 1 formed from a mold blank and placed on the silicone bag mold 2. The silicone bag mold 2 includes an upper mold 21, a lower mold 23, and multiple molding components 224. The bottom of the upper mold 21 can close with the top of the lower mold 23 to form multiple storage cavities for accommodating the multiple molding components 224. The outer wall of the molding component 224 and the inner wall of the storage cavity together form a molding space for forming a silicone bag. When external silicone raw material is placed in the molding space, the silicone bag mold can remelt the silicone raw material into the molding space through heating. The silicone raw material molten in the molding space can form a silicone bag that fits onto the molding component after cooling, according to the shape of the molding space. The silicone bag can be demolded by separating the upper mold and the lower mold. After demolding, it can also be used to add external silicone raw material, improving the ease of operation of the equipment during the silicone bag manufacturing process.

[0055] In this embodiment, as Figure 2-5 As shown, the forming component 224 includes a fixing member 221, a bag body component 222, and a connecting component module 1 installed between the fixing member 221 and the bag body component 222. The tail end of the fixing member 221 protrudes with a protrusion 2211 for the connecting component module 1 to be fitted onto. The end of the protrusion 2211 away from the fixing member can be placed inside the head end of the bag body component. The head end of the connecting component module 1 is connected to the tail end of the fixing member 221, and the tail end is connected to the head end of the bag body component 222. The fixing member can limit the connection position between the fixing member and the bag body component through the connection between the protrusion and the bag body component, increasing the stability of the connection between the fixing member and the bag body component. The connecting component module can be attached to the protrusion by separating the fastener and the bag body, or it can be detached from the protrusion by separating the fastener and the bag body. This detachable method is conducive to replacing the connecting component module, thereby changing the shape of the molding space and changing the molding structure of the silicone bag. Moreover, the detachable method allows the fastener, connecting component module and bag body to be manufactured separately, and different production methods can be achieved by the differences in the shape of the fastener, connecting component module and bag body.

[0056] In this embodiment, the connecting component module 1 is an annular body with an arc-shaped top and bottom surface, located on the upper part of the silicone bag mold 2. The connecting component module 1 has a connecting channel 11 penetrating the first and last surfaces. The top and bottom surfaces are respectively formed by concave areas of the same arc degree, creating a top concave area 12 and a bottom concave area 13. The first and two sides of the top and bottom concave areas 12 and 13 are connected to the outside, and the two ends of the last surface are connected to the outside, forming a protruding limiting strip 14. Multiple arc-shaped concave teeth 15 are recessed along the direction of the limiting strip 14 on the top and bottom concave areas 12 and 13, respectively. Each spacer 16 formed between two concave teeth 15 has a protruding tooth 17 matching the shape of the concave tooth 15. The side of each concave tooth 15 and protruding tooth 17 near the limiting strip 14... The outer wall of the corresponding limiting strip 14, which is far from the tail side of the connecting component module, is connected to the outer wall. The continuous arrangement of the protruding teeth and concave teeth on the top concave area and the arrangement of the protruding teeth and concave teeth on the bottom concave area facilitates the cooling of the molten silicone raw material in the molding space to form two toothed protrusions placed on the two inner sides of the silicone bag opening. The corresponding arrangement of each protruding tooth on the top concave area and each concave tooth on the bottom concave area, and the corresponding arrangement of each concave tooth on the top concave area and each protruding tooth on the bottom concave area, allows each protruding tooth of one toothed protrusion to be embedded in each concave tooth of the other toothed protrusion, and each protruding tooth of the other toothed protrusion to be embedded in each concave tooth of one toothed protrusion. Thus, the mutual embedding and connection or separation of the two toothed protrusions provides a toothed locking element for sealing and opening the bag opening of the silicone bag. The top recessed area 12 and the bottom recessed area 13 are respectively provided with a first groove 121 and a second groove 131. The first groove 121 has a first convex strip 122 and a second convex strip 132 protruding from the surface of the top recessed area 12 on both sides of the groove opening. The second groove 131 has a third convex strip 132 protruding from the groove opening on the bottom of the groove. The first groove 121, the second groove 131, the first convex strip 122, the second convex strip 123 and the third convex strip 132 are all arranged at intervals along the arrangement direction of the limiting strip 14 and the outer side of the corresponding convex teeth 17 and concave teeth 15. The second groove can form a correspondence with the first convex strip and the second convex strip by the setting of the third convex strip on both sides of the third convex strip. The two concave sections and the third convex section correspond to the first groove. The arrangement of the first groove, the first convex section, and the second convex section facilitates the formation of a first connecting member on one inner side of the silicone bag opening by the molten silicone material within the molding space. The arrangement of the second groove and the third convex section facilitates the formation of a second connecting member on the other inner side of the silicone bag by the molten silicone material within the molding space. The first connecting member can be interlocked with or detached from the second connecting member, thereby providing a strip-shaped sealing element for the silicone bag that can seal or open at the bag opening. The strip-shaped sealing element and the toothed sealing element can provide a double sealing effect for the silicone bag, which helps to increase the sealing performance of the silicone bag. The processing equipment includes a mounting base for fixing the mold blank and a switching mechanism for changing the 3D printer head and the grinding head.The processing equipment is an integrated processing device combining 3D printing and five-axis CNC. The 3D printer head can perform 3D printing operations on the mold blank, and the grinding head can perform grinding and polishing operations on the mold blank. Compared with the traditional single grinding process, the alternating combination of 3D printing and grinding / polishing operations solves the technical difficulty that the traditional grinding head cannot enter the concave tooth to polish its inner wall due to the restriction of two adjacent convex teeth. By first grinding the concave teeth and then printing and polishing the convex teeth in a layer-by-layer manner, the grinding head can reduce the tilt angle of the blade without being restricted by the convex teeth, thereby completing the grinding and polishing of the inner curved wall of the concave teeth.

[0057] In this embodiment, the inner wall of the concave tooth near the limiting strip is the outer wall of the limiting strip and is arranged parallel to the inner wall away from the limiting strip. The peripheral wall arranged along the two inner walls is a continuous curved surface, forming an arc-shaped peripheral wall. The top of the concave tooth has an opening communicating with the outside. Adjacent concave teeth can form a gap between the two concave teeth through the arrangement of each opening. The gap has a convex tooth with a shape identical to each concave tooth. The convex tooth includes an upper half and a lower half. The bottom surface of the lower half of the convex tooth is connected to the top surface of the gap and is identical to the top surface of the gap. The top surface of the lower half of the tooth and the bottom surface of the upper half of the tooth are the surfaces with the largest cross-sectional area of ​​the tooth. The cross-sectional area of ​​the lower half of the tooth gradually decreases from top to bottom and is adapted to the upper half of the concave tooth with an opening. The cross-sectional area of ​​the upper half of the tooth gradually increases from top to bottom and is adapted to the lower half of the concave tooth away from the opening. The outer wall of the tooth can form a continuous curved surface with the inner wall of the concave tooth, which is conducive to the molten silicone raw material forming a tooth on the opening of the silicone bag on the concave tooth of the connecting component module, and forming a concave tooth on the tooth of the connecting component module that is adapted to the tooth on the opening of the silicone bag.

[0058] The method for producing silicone packaging bags disclosed in this embodiment can be used to produce silicone bag molds described in the foregoing embodiments, combined with the above structure and as follows. Figure 6 As shown, the production method of this silicone packaging bag may include the following steps.

[0059] Step S1: After the mold blank is fixed on the mounting base, the grinding head mounted on the switching mechanism is controlled to move for the first processing step. The grinding head can form a top recessed area, a bottom recessed area and a connecting channel by grinding and polishing the mold blank.

[0060] The mounting base can drive the mold blank to move at any angle, and the grinding head can increase the grinding angle on the mold blank through the cooperation of the mold blank, thereby increasing the structural complexity of grinding on the mold blank by the grinding head.

[0061] In this embodiment, after the grinding head is installed on the switching mechanism, the control processing equipment sets the working head at the bottom of the grinding head as the TCP point (tool coordinate center), that is, sets the working head as the tool coordinate origin of the switching mechanism. This is beneficial for the grinding head to move with the movement of the working head as the reference, thereby improving the accuracy of grinding when the working head rotates.

[0062] After the mold blank is fixed on the mounting base, the mounting base is controlled to adjust the mold blank to the first state with the head facing upward. After the mold blank is adjusted to the first state, the actuating head can move to the preparation point above the mold blank, which facilitates the grinding of the connecting channel on the mold blank. When the actuating head is placed at the preparation point, the grinding rotation of the actuating head is controlled and the actuating head is moved to the area where the connecting channel is located at the head of the mold blank. By confirming the starting grinding point of the connecting channel, it is beneficial for the actuating head to complete the grinding operation of the connecting channel from top to bottom according to the shape of the connecting channel. Moreover, the actuating head can complete the polishing operation of the inner wall of the connecting channel after the grinding of the connecting channel is completed.

[0063] After the actuating head completes polishing of the connecting channel, it returns to the preparation point without the grinding head touching the mold blank. This prepares the mounting base to adjust the mold blank to its second state with the top surface facing upwards, preventing collisions with the grinding head during mold blank assembly adjustment. When the actuating head reaches the preparation point, the mounting base moves the mold blank below the actuating head and adjusts it to the second state. When the mold blank is in the second state, the actuating head moves to one side of the area with the concave top surface on the mold blank. By confirming the starting grinding point of the concave top surface, the actuating head can complete the grinding operation of the concave top surface from one side to the other on the top surface of the mold blank, according to the formation of the concave top surface. Furthermore, the actuating head can complete the polishing operation of the inner wall of the concave top surface after grinding.

[0064] After the actuating head completes polishing of the top recessed area, it returns to the preparation point without the grinding head touching the mold blank. This prepares the mounting base to adjust the mold blank to the third state with the bottom surface facing upwards, preventing collisions with the grinding head during mold blank assembly adjustment. When the actuating head reaches the preparation point, the mounting base moves the mold blank below the actuating head and simultaneously adjusts the mold blank to the third state. When the mold blank is in the third state, the actuating head moves to the side of the bottom surface of the mold blank where the bottom recessed area to be ground is located. By confirming the starting grinding point of the bottom recessed area, the actuating head can complete the grinding operation of the bottom recessed area from one side of the mold blank to the other on the top surface of the mold blank according to the shape of the bottom recessed area. Furthermore, the actuating head can complete the polishing operation of the inner wall of the bottom recessed area after grinding.

[0065] The top and bottom surfaces of the mold blank are both arc-shaped. The mounting base can control the mold blank to cooperate with the operation of the working head during the grinding process. This is beneficial for the working head to perform grinding and polishing operations on the top and bottom concave areas according to the arc of the top and bottom surfaces of the blank.

[0066] Step S2: After the first processing movement of the switching mechanism is in place, the grinding head is controlled to move for the second processing movement with the switching mechanism. The grinding head can grind multiple concave teeth and a first groove placed on the top concave area, as well as multiple concave teeth and a second groove placed on the bottom concave area on the mold blank.

[0067] In this embodiment, the mold blank can be adjusted by the mounting base to cooperate with the actuating head. The adjustment of the mold blank facilitates the actuating head to form concave tooth structures with inner arc-shaped inner walls on the mold blank. It also facilitates the actuating head to grind the first groove, the second groove, and each concave tooth on the top and bottom concave areas, which are arranged with the same arc as the top surface of the top and bottom concave areas.

[0068] In this process, after the actuating head completes the grinding operation of a single structure, it completes the polishing operation of each concave tooth, the inner wall of the first groove and the second groove through the cooperation of the mold blank, which can improve the smoothness of the grinding part and thus improve the product quality.

[0069] In this embodiment, as Figure 7 As shown, step S2 can also specifically include the following steps:

[0070] Step S21: After the grinding head completes the polishing operation on the bottom concave area, the control switching mechanism drives the grinding head to the preparation point. The mounting base can control the mounting base to adjust the mold blank to the first preparation state with the top concave area facing upward after the grinding head moves to the preparation point. When the mold blank is adjusted to the first preparation state, the control action head moves with the grinding head from one side of the top concave area to the other side to grind and form multiple concave teeth in sequence. After the action head completes the grinding of each concave tooth, the control action head moves back and forth between the other side of the top concave area and one side of the top concave area with the grinding head and grinds to form the first groove.

[0071] In this embodiment, when the mold blank is adjusted to the first ready state, the control head moves to the concave tooth area closest to the bottom concave area. By confirming the starting position of the concave tooth, it is beneficial for the control head to perform layer-by-layer grinding operation on the concave tooth from top to bottom according to the shape of the concave tooth. After the grinding operation on the concave tooth is completed, the concave tooth can be polished. After the polishing operation on the concave tooth is completed, the control head can move to the top concave area without touching the grinding blank. This is beneficial for preparing the control head for the grinding operation on the next concave tooth and prevents the control head from contacting the mold blank when it moves to the starting grinding position of the next concave tooth.

[0072] In this embodiment, when the actuating head moves above the top concave area, it can repeat the grinding process of the previous concave tooth to sequentially grind and polish the remaining concave teeth. By sequentially grinding each concave tooth in the top concave area, the actuating head can reduce the required movement path, thereby improving the grinding efficiency. After completing the grinding and polishing of each concave tooth in the top concave area, when the actuating head moves above the top concave area, it is controlled to move to the area where the first groove is provided in the top concave area. By confirming the starting position of the first groove, it is beneficial for the actuating head to perform back-and-forth layer-by-layer grinding and polishing operations on the first groove along the direction of the limiting strip.

[0073] After polishing each tooth in the top concave area, the actuating head is placed on the other side of the top concave area. The grinding start position of the first groove is located on the other side of the top concave area. This allows the actuating head to start grinding the first groove with the shortest movement path after completing the sequential grinding of each tooth in the top concave area, thereby improving the working efficiency of the actuating head.

[0074] Step S22: After the actuating head completes the grinding of the first groove with the movement of the grinding cutter, the control switching mechanism drives the grinding cutter to the preparation point. The mounting base can control the mold blank to adjust to the second preparation state after the grinding cutter moves to the preparation point. When the mold blank is adjusted to the second preparation state, the control actuating head moves with the grinding cutter from one side of the bottom concave area to the other side and grinds in sequence at intervals to form multiple concave teeth. After the actuating head completes the grinding of each concave tooth, the control actuating head moves back and forth between the other side of the bottom concave area and one side of the bottom concave area with the grinding cutter and grinds to form the second groove. The actuating head can turn off the grinding rotation after completing the grinding operation of the second groove.

[0075] In this embodiment, when the mold blank is adjusted to the second ready state, the control head moves to the top surface of the toothed area on one side of the bottom recess. At this time, the control head can complete the grinding operation of each tooth in the bottom recess by repeating the grinding steps of each tooth in the top recess, so that the control head can complete the grinding operation of each tooth in the bottom recess sequentially from one side of the bottom recess to the other side. When the control head is placed above the bottom recess and on the other side of the bottom recess after completing the grinding operation of each tooth in the bottom recess, the control head moves to the top surface of the second groove area in the bottom recess. By confirming the starting position of the second groove, it is beneficial for the control head to perform back-and-forth layer-by-layer grinding operation on the second groove along the arrangement direction of the limiting strip.

[0076] In this process, after grinding each concave tooth in the concave area, the working head that moves to the top of the concave area is placed on the other side of the concave area. The grinding starting position of the second groove is located on the other side of the concave area. This allows the working head to start grinding the second groove with the shortest movement path after completing the grinding operation of each concave tooth in the concave area, thereby improving the grinding efficiency of the working head.

[0077] Step S3: After the second processing movement of the switching mechanism is in place, control the switching mechanism to change the grinding head to the 3D printer head. After the switching mechanism completes the switching of the 3D printer head, control the 3D printer head to perform a third processing movement with the switching mechanism to print and form multiple protruding teeth placed on the top surface of each interval in the top recessed area and the top surface of each interval in the bottom recessed area.

[0078] The mold blank can be adjusted by the mounting base to cooperate with the discharge port of the 3D printer head, which is beneficial for the 3D printer head to complete the printing operation of each tooth.

[0079] In this embodiment, as Figure 8 As shown, step S3 can also specifically include the following steps:

[0080] Step S31: When the switching mechanism completes the switching of the 3D printer head, control the switching mechanism to move the 3D printer head to the preparation point above the mold blank. When the 3D printer head moves to the preparation point, control the mounting base to adjust the mold blank to the first preparation state with the top concave area facing upward.

[0081] In this embodiment, after the working head completes the polishing operation on the second groove, the switching mechanism moves the grinding head to the replacement area and replaces the grinding head with the 3D printer head. When the switching mechanism completes the installation of the 3D printer head, the control processing equipment sets the discharge port at the bottom of the 3D printer head as the TCP point (tool coordinate center), that is, sets the 3D printer head as the tool coordinate origin of the switching mechanism. This is beneficial for the 3D printer head to move with the discharge port as the reference during the movement, thereby improving the accuracy of the 3D printer head during printing.

[0082] When the switching mechanism completes the installation of the 3D printer head, it controls the 3D printer head to heat the discharge port at a set temperature.

[0083] Step S32: When the mold blank is in the first preparation state, control the 3D printer head to move to the top surface of each interval in the top and bottom recesses in sequence by following the switching mechanism for the third processing movement. When the 3D printer head moves to the top surface of the interval, control the 3D printer head to print the corresponding convex teeth on the top surface of the interval according to the convex tooth shape.

[0084] Specifically, when the discharge port reaches the set printing area, the discharge operation of the discharge port is started; when the discharge port exceeds the set printing area, the discharge operation of the discharge port is stopped. This allows the discharge port to complete the corresponding printing operation by controlling the discharge of material.

[0085] In this embodiment, as Figure 9 As shown, step S32 may further include the following steps:

[0086] Step S321: When the mold blank is in the first preparation state, control the 3D printer head to move the discharge port to the printing point on the top surface of the interval near the concave side.

[0087] The printing point is the starting position for printing the lower half of the tooth on the top surface of the interval.

[0088] Step S322: When the discharge port moves to the printing point and the discharge port reaches the set temperature, control the discharge port to discharge material and simultaneously control the discharge port of the 3D printer head to move layer by layer to print the top surface of the interval part according to the shape of the lower half of the tooth. The discharge port can complete the printing of the lower half of the tooth with the movement of the 3D printer head.

[0089] Step S323: When the ejector port moves with the 3D printer head after printing, stop ejecting material from the ejector port and simultaneously control the ejector port to move with the 3D printer head to the printing point on the top surface of the next interval.

[0090] When the discharge port finishes printing the lower half of the protrusion, it controls the discharge port to move upward to a set lifting height. When the discharge port finishes moving to the lifting height, it controls the discharge port to move to the printing point on the top surface of the next interval. This helps to prevent the discharge port from contacting or colliding with the mold blank during the printing process of the part directly moving to the top surface of the next interval.

[0091] Step S324: When the discharge port reaches the printing point on the top surface of the next interval section with the 3D printer head, repeat steps S322-S323 and sequentially complete the lower half of the protruding teeth placed on the top and bottom recessed areas.

[0092] In this embodiment, when the discharge port completes the printing of the lower half of the protruding teeth on the top surface of each interval from one side of the top recess area to the other along the arrangement direction of the intervals on the top recess area, the discharge port is controlled to return to the preparation point without touching the mold blank. When the discharge port reaches the preparation point, the mounting base is controlled to adjust the mold blank to the second preparation state, which is beneficial for preparing for the printing of each protruding tooth on the bottom recess area. When the mold blank is in the second preparation state, the discharge port is controlled to move to the printing point on the top surface of the interval near the bottom recess area and repeat the printing steps of the lower half of the protruding teeth on the top recess area to complete the printing of the lower half of each protruding tooth on the bottom recess area.

[0093] When the printing operation at the discharge port is completed, the heating at the discharge port is stopped, which helps the discharge port to cool down as it moves to a specific point, thus improving the working efficiency of the equipment.

[0094] Step S33: When the switching mechanism completes the third processing movement, control the switching mechanism to change the 3D printer head to the grinding head. When the grinding head switching is completed, control the switching mechanism to drive the grinding head to the preparation point. The mounting base can adjust the mold blank to the first preparation state after the grinding head reaches the preparation point.

[0095] When the switching mechanism completes the installation of the grinding head, the control processing equipment sets the working head as the tool coordinate origin of the switching mechanism to facilitate the grinding operation of the working head.

[0096] Step S34: When the mold blank is in the first preparation state, control the 3D printer head to move around the outer wall of each tooth in sequence with the movement of the switching mechanism and complete the polishing of the tooth.

[0097] During the polishing process of the actuating head on the protruding teeth, the mounting base drives the mold blank to perform a polishing operation adapted to the actuating head, which is beneficial for the actuating head to perform a comprehensive polishing operation on the protruding teeth.

[0098] In this embodiment, as Figure 10 As shown, step S34 may further include the following steps:

[0099] Step S341: When the mold blank is in the first ready state, start the grinding head to rotate and simultaneously control the grinding head to move to the polishing point on the outer wall of the lower half of the protruding tooth near the top concave area.

[0100] The grinding point is the starting grinding position of the lower half of the corresponding tooth, which makes it easy for the working head to polish the outer wall of the lower half of the tooth according to the grinding point.

[0101] Step S342: When the actuating head moves with the grinding head to the polishing point, the actuating head can move along the outer wall of the lower half of the tooth layer by layer with the grinding head and complete the polishing operation of the lower half of the tooth.

[0102] Step S343: After the working head finishes polishing the outer wall of the lower half of the tooth, control the working head to move to the polishing point on the outer wall of the next lower half of the tooth and repeat steps S342-S343 to complete the polishing operation of each lower half of the tooth in sequence. After the working head finishes polishing the lower half of each tooth, stop the rotation of the working head.

[0103] In this process, after the actuating head completes the polishing operation on the lower half of the outer wall of each tooth in the top concave area, the mounting base is controlled to adjust the mold blank to the second ready state, which facilitates the actuating head to polish the lower half of each tooth in the bottom concave area. When the mold blank is adjusted to the second state, the actuating head is controlled to move to the polishing point on the lower half of the outer wall of the tooth on one side of the bottom concave area, which helps the actuating head to complete the polishing operation on the lower half of the outer wall of each tooth in the bottom concave area in sequence.

[0104] In this embodiment, when the actuating head completes polishing of the lower half of each tooth, by repeating the printing method of the actuating head on the top and bottom recessed areas of each tooth, the actuating head can complete the printing of the top and bottom recessed areas and the upper half of the tooth according to the shape of the upper half of the tooth based on the printing points on the top surface of each tooth. When the actuating head completes printing of the upper half of each tooth, by repeating the polishing method of the actuating head on the top and bottom recessed areas of each tooth, the actuating head can complete the polishing operation of the upper half of each tooth based on the polishing points on the outer wall of each tooth. Compared to printing the entire tooth, dividing the tooth into an upper and lower half for separate printing and polishing facilitates the polishing of the outer wall of the tooth by the actuating head. The lower half of the tooth has a curved surface that curves inward from top to bottom by changing its cross-sectional area. By printing and polishing the lower half of the tooth first, the upper half of the tooth, which is opposite to the polishing surface, can be prevented from restricting the actuating head or grinding head, which helps to increase the range of motion of the mold blank in relation to the actuating head.

[0105] Step S4: After the third processing movement of the switching mechanism is in place, control the 3D printer head to perform a fourth processing movement with the switching mechanism to print the first and second convex strips placed on the top concave area, and the third convex strip placed on the bottom concave area.

[0106] During the movement or printing process of the 3D printer head, the mold blank can be adjusted to cooperate with the movement of the 3D printer head through the adjustment of the mounting base, which is beneficial for the 3D printer head to print the first convex strip, the second convex strip and the third convex strip on the arc-shaped surface of the mold blank.

[0107] Specifically, when the discharge port reaches the set printing area, the discharge operation of the discharge port is started; when the discharge port exceeds the set printing area, the discharge operation of the discharge port is stopped. This allows the discharge port to complete the corresponding printing operation by controlling the discharge of material.

[0108] In this embodiment, as Figure 11 As shown, step S4 can also specifically include the following steps:

[0109] Step S41: After the grinding head completes the polishing operation on each tooth, the control switching mechanism changes the grinding head to the 3D printer head. When the 3D printer head switching is completed, the control switching mechanism moves the 3D printer head to the preparation point. The mounting base can adjust the mold blank to the first preparation state when the 3D printer head moves to the preparation point.

[0110] When the 3D printer head is installed, the ejector port is heated to a set temperature. This allows the ejector port to be heated during the preparation and adjustment process of the 3D printer head and the mold blank, which helps to shorten the waiting time for the ejector port to reach the set temperature when printing is required, thereby improving the working efficiency of the equipment.

[0111] Step S42: When the mold blank is adjusted to the first ready state, control the 3D printer head to move the discharge port to the top concave area and complete the printing of the first and second convex strips. The opening of the first groove can be repeatedly moved between one side and the other side of the top concave area by the discharge port of the 3D printer head to complete the layer-by-layer printing of the first and second convex strips.

[0112] Step S43: After the 3D printer head's ejector port completes the layer-by-layer printing of the first and second protrusions, control the 3D printer head to return to the preparation point. When the 3D printer head reaches the preparation point, control the mold blank to adjust to the second preparation state with the concave surface facing upwards. When the mold blank is adjusted to the second preparation state, control the ejector port to move with the 3D printer head to the inner bottom wall of the second groove and complete the printing of the third protrusion. The third protrusion on the inner bottom wall can be repeatedly moved between one side and the other side of the concave area by the ejector port to complete the layer-by-layer printing of the third protrusion.

[0113] In particular, after the third convex strip is printed at the discharge port, the heating at the discharge port is stopped, which helps to increase the cooling time of the discharge port.

[0114] Step S44: After the 3D printer head's output port completes the layer-by-layer printing of the third convex strip, the control switching mechanism changes the 3D printer head to the grinding head and sequentially polishes the first, second, and third convex strips.

[0115] In this embodiment, the polishing operation is performed after the first, second, and third convex strips are printed at the discharge port of the 3D printer head. Compared with the method of printing the first and second convex strips first and then polishing them, and then printing the third convex strip and then polishing them, the number of times the switching mechanism needs to switch and install the 3D printer head and the grinding head can be reduced, thereby improving the working efficiency of the equipment.

[0116] The fasteners and bag body are formed by casting followed by grinding and polishing. By casting the relatively simple fasteners and bag body, production costs can be reduced. Then, the connecting component module, which is processed from the mold blank, is fitted onto the protrusion of the fastener. The silicone bag mold can be produced by connecting the fasteners, the connecting component module, and the bag body.

[0117] In this embodiment, the processing equipment can complete the fabrication of the connecting component module by combining grinding operations on the mold blank with 3D printing operations. Compared with the traditional processing method of directly grinding the mold blank to form concave and convex teeth, this method can solve the problem that the grinding head cannot penetrate between two adjacent convex teeth due to the limitation of convex teeth, thus preventing the grinding head from completing the grinding operation on the concave teeth. The processing equipment can first complete the grinding operation on each concave tooth, the first groove and the second groove through the grinding head, so that the grinding head can increase the range of motion of the grinding head relative to the mold blank without the limitation of convex teeth, thereby completing the grinding and polishing of the inner arc wall of the concave teeth. This is beneficial for the molten silicone material placed in the molding space to form a double seal at the mouth of the silicone bag according to the outer wall of the connecting component module.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0119] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
