Description

Technical Field

[0001] This application relates to the field of injection molding technology, and in particular to an injection mold, an injection system and a control method thereof. Background Technology

[0002] Injection molds are tools used to produce plastic parts, and the process is carried out using an injection molding machine. For example, molten plastic material is injected into the closed cavity of a mold, and after cooling and solidification, a product of a specific shape is formed. This technology is widely used in the manufacture of various products, such as daily necessities, automotive parts, and electronic device housings. However, some plastic products do not meet practical requirements in terms of physical properties such as strength and rigidity.

[0003] In related technologies, high-performance inserts are placed on the wall of the injection mold and cooled and molded together with the fluid plastic to become part of the product wall thickness, thereby significantly improving the physical properties of the product. However, this method can only improve the physical properties of the product in a localized area. For example, the strength and rigidity of the product will be improved in the area near the high-performance insert. Moreover, the insert may detach from the product during use. Summary of the Invention

[0004] This application aims to at least address the problems existing in the prior art, which can only improve the local physical properties of the product and still face the issue of inserts detaching from the product during use. To this end, this application proposes an injection mold, an injection molding system, and a control method thereof.

[0005] In a first aspect, this application provides an injection mold, comprising: Upper mold, which defines the upper mold groove and the injection runner; The lower mold defines a lower mold groove corresponding to the upper mold groove. The upper mold groove is adapted to enclose the lower mold groove to form a closed mold cavity, and the closed mold cavity is connected to the injection runner. A reinforcing plate, the reinforcing plate including a cutting area and a reinforcing area connected to the cutting area; The upper mold has a first position and a second position. When the upper mold is in the first position, both the upper mold and the lower mold abut against the cutting area, and the reinforcing area is located within the sealed mold cavity. When the upper mold is in the second position, the upper mold is separated from the cutting area.

[0006] By adopting the above technical solution, both the upper and lower molds abut against the cutting area of ​​the reinforcing plate, thereby fixing the reinforcing area of ​​the reinforcing plate in the middle of the sealed mold cavity. After the product is formed, the reinforcing area of ​​the reinforcing plate is inside the product, which can improve the overall strength and rigidity of the product, and at the same time prevent the reinforcing area of ​​the reinforcing plate from detaching from the product during use, thereby improving the reliability and durability of the product.

[0007] According to one embodiment of this application, the cutting area is located on at least one side of the reinforcing area, the lower mold has a notch, and the cutting area overlaps the notch.

[0008] By adopting the above technical solution, the cutting area overlaps with the notch of the lower mold, and when both the upper and lower molds abut against the cutting area of ​​the reinforcing plate, a better sealed mold cavity can be formed.

[0009] According to one embodiment of this application, the reinforced region is provided with reinforcing patterns, which are distributed on at least one side of the reinforced region.

[0010] By adopting the above technical solution, the strength and rigidity of the molded product can be increased under this implementation method.

[0011] According to one embodiment of this application, the upper mold includes: a first mold body and a first mold core, the first mold core being detachably connected to the first mold body, and the first mold core defining the upper mold groove; The lower mold includes a second mold body and a second mold core, the second mold core being detachably connected to the second mold body, and the second mold core defining the lower mold groove.

[0012] By adopting the above technical solution and through this design, on the one hand, different first mold cores and second mold cores can be disassembled and replaced, thereby defining different sealed mold cavities between the first mold core and the second mold core, and forming products of different shapes. On the other hand, the detachable connection method also facilitates the replacement of damaged first mold cores and second mold cores.

[0013] According to one embodiment of this application, the injection mold further includes: a cutting component; The cutting component is disposed between the first mold core and the first mold body. The first mold core has a cutting hole, and the second mold core has a cutting groove corresponding to the position of the cutting hole. The cutting end of the cutting component is adapted to pass through the cutting hole to cut the cutting area.

[0014] By adopting the above technical solution, after the product is formed, the cutting end of the cutting component passes through the cutting hole to cut the cutting area, so as to separate the cutting area from the reinforcing area. This design improves the product production efficiency compared to cutting off the cutting area on the side of the product after taking the product out of the closed mold cavity.

[0015] According to one embodiment of this application, a first cooling channel is provided in the upper mold, and the first cooling channel is arranged around the sealed mold cavity; a second cooling channel is provided in the lower mold, and the second cooling channel is arranged around the sealed mold cavity.

[0016] By adopting the above technical solution, the first cooling channel is arranged around the closed mold cavity, and the second cooling channel is arranged around the closed mold cavity. This can transfer heat from the inside of the closed mold cavity more evenly and effectively, accelerate the cooling process of the product, and at the same time, uniform cooling helps to reduce uneven stress distribution inside the product caused by uneven cooling, thus avoiding product deformation and cracks.

[0017] According to one embodiment of this application, the bottom surface of the lower mold groove is provided with a through hole, and the lower mold groove is provided with a receiving piece suitable for closing the through hole; When the upper mold is in the second position, the through hole is used for the telescopic end of the lifting device to pass through, and the telescopic end of the lifting device pushes the receiving piece out of the lower mold groove.

[0018] By adopting the above technical solution, the telescopic end of the lifting device contacts the receiving plate, and the product is pushed out through the receiving plate, thus protecting the integrity of the product.

[0019] Secondly, this application provides an injection molding system, including: an injection mold, a lifting device, a positioning device, a material handling device, and a controller; The injection mold is used for injection molding products. The lifting device is located below the injection mold, the positioning device is located above the injection mold, and the material handling device is located on the side of the injection mold.

[0020] By adopting the above technical solution and electrically connecting the lifting device, positioning device, and material handling device through the controller, the entire injection molding process is automated, reducing manual intervention and operation, and improving production efficiency and consistency. Furthermore, the optimized process flow reduces unnecessary waiting and repetitive actions, thereby shortening the production cycle and increasing production efficiency.

[0021] According to one embodiment of this application, the injection molding system further includes: a base; The lifting device, the positioning device, and the material handling device are all mounted on the base.

[0022] Thirdly, this application provides a control method for an injection molding system, including: The telescopic end of the lifting device is controlled to pass through the through hole, abut against the receiving piece, and move upward to the third position in sequence. When the receiving piece moves to the third position, the clamping end of the positioning device is sequentially controlled to clamp and fix the upper mold. When the telescopic end of the lifting device abuts against the receiving piece, the telescopic end of the lifting device is controlled to move down to the fourth position, and the material handling device is controlled to remove the product.

[0023] By adopting the above technical solution and electrically connecting the lifting device, positioning device, and material handling device through the controller, the entire injection molding process is automated, reducing manual intervention and operation, and improving production efficiency and consistency. Furthermore, the optimized process flow reduces unnecessary waiting and repetitive actions, thereby shortening the production cycle and increasing production efficiency.

Detailed Implementation

[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] First, in order to facilitate the description of the relative positions and locations of the various institutions in this application, the implementation scenarios of the embodiments of this application will be explained here.

[0033] An injection mold is a tool used to produce plastic parts, which is done using an injection molding machine. For example, molten plastic material is injected into the closed cavity of a mold, and after cooling and solidification, it forms a product of a specific shape.

[0034] This technology is widely used in the manufacture of various products, but some products made of plastic do not meet practical requirements in terms of physical properties such as strength and rigidity. Examples include everyday consumer goods, car dashboards, and implantable medical devices.

[0035] In related technologies, high-performance inserts are placed on the walls of injection molds and cooled and molded together with the fluid plastic to become part of the product wall thickness, thereby significantly improving the physical properties of the product.

[0036] However, this approach often only improves the physical properties of the product in certain areas. For example, the strength and stiffness of the product may be improved in the area near the high-performance insert, but the insert may also detach from the product during use.

[0037] The following is for reference. Figures 1-11 This application describes an injection mold 10, an injection system, and a control method thereof according to embodiments thereof.

[0038] like Figures 1-3 As shown, the injection mold 10 includes: an upper mold 100, a lower mold 200, and a reinforcing plate 300.

[0039] The upper mold 100 defines the upper mold groove 111 and the injection runner 112.

[0040] The lower mold 200 defines a lower mold groove 211 corresponding to the upper mold groove 111. The upper mold groove 111 is adapted to enclose the lower mold groove 211 to form a closed mold cavity a, and the closed mold cavity a is connected to the injection flow channel 112.

[0041] The reinforcing plate 300 includes a cutting area 310 and a reinforcing area 320 connected to the cutting area 310.

[0042] The reinforcing plate 300 should have good mechanical strength, rigidity and good bonding ability with plastic. The reinforcing plate 300 can be made of metal materials such as steel, aluminum or copper, or composite materials. This embodiment does not impose any restrictions.

[0043] It should be noted that the reinforced area 320 and the cutting area 310 can be formed using the same material, or they can be formed using different materials.

[0044] When the reinforcing region 320 and the cutting region 310 are made of the same material, the connection area between the reinforcing region 320 and the cutting region 310 can be designed with a weak point where stress is concentrated, so as to facilitate the separation of the reinforcing region 320 and the cutting region 310 in subsequent steps.

[0045] When the reinforcing area 320 and the cutting area 310 are formed from different materials, the cutting area 310 can be made of a material with lower strength to facilitate the separation of the reinforcing area 320 and the cutting area 310 in subsequent steps.

[0046] The upper mold 100 has a first position and a second position.

[0047] like Figure 1 As shown, when the upper mold 100 is in the first position, both the upper mold 100 and the lower mold 200 abut against the cutting area 310, and the reinforcing area 320 is located in the sealed mold cavity a.

[0048] Both the upper mold 100 and the lower mold 200 abut against the cutting area 310 of the reinforcing plate 300, thereby fixing the reinforcing area 320 of the reinforcing plate 300 in the middle of the sealed mold cavity a. The middle refers to any position between the bottom wall surface and the top wall surface of the sealed mold cavity a. In implementation, the dimensions of the upper mold 100 and the lower mold 200 can be adjusted according to actual needs to change the actual position of the middle part. This embodiment does not limit this.

[0049] In this embodiment, molten plastic can be injected into the injection runner 112, which fills the closed mold cavity a, thereby wrapping the reinforcing area 320 of the reinforcing plate 300. After the molten plastic cools down, product b is formed, at which time product b has the reinforcing area 320 of the reinforcing plate 300.

[0050] like Figure 2 and Figure 3 As shown, when the upper mold 100 is in the second position, the upper mold 100 is separated from the cutting area 310.

[0051] In this embodiment, product b can be removed from the sealed mold cavity a. Since the cutting area 310 of the reinforcing plate 300 is outside the product b, the cutting area 310 of the reinforcing plate 300 can be separated from the product b by cutting.

[0052] In the above embodiments of this application, both the upper mold 100 and the lower mold 200 abut against the cutting area 310 of the reinforcing plate 300, thereby fixing the reinforcing area 320 of the reinforcing plate 300 in the middle of the sealed mold cavity a. After the product b is formed, the reinforcing area 320 of the reinforcing plate 300 is located inside the product b. This can improve the overall strength and rigidity of the product b, and at the same time, it can prevent the reinforcing area 320 of the reinforcing plate 300 from detaching from the product b during use, thereby improving the reliability and durability of the product b.

[0053] like Figure 4 As shown, in some embodiments, the cutting area 310 is located on at least one side of the reinforcing area 320, and the lower mold 200 has a notch, with the cutting area 310 overlapping the notch.

[0054] In this embodiment, the cutting area 310 overlaps the notch of the lower mold 200. When both the upper mold 100 and the lower mold 200 abut against the cutting area 310 of the reinforcing plate 300, a sealed mold cavity a can be formed more effectively.

[0055] like Figure 4 As shown, in actual implementation, the reinforced region 320 is provided with reinforcing ridges 321, which are distributed on at least one side of the reinforced region 320.

[0056] For example, there are multiple reinforcing ridges 321, which are distributed at intervals on the upper and lower sides of the reinforcing area 320 of the reinforcing plate 300. The extension direction of each reinforcing ridge 321 can be perpendicular to the reinforcing area 320 of the reinforcing plate 300. In this embodiment, the strength and rigidity of the molded product b can be increased.

[0057] like Figure 5 and Figure 6 As shown, in some embodiments, the upper mold 100 includes a first mold body 120 and a first mold core 110, the first mold core 110 being detachably connected to the first mold body 120, and the first mold core 110 defining an upper mold groove 111.

[0058] The lower mold 200 includes a second mold body 220 and a second mold core 210. The second mold core 210 is detachably connected to the second mold body 220, and the second mold core 210 defines a lower mold groove 211.

[0059] In this embodiment, the first mold core 110 is detachably connected to the first mold body 120, and the second mold core 210 is detachably connected to the second mold body 220. The detachable connection methods of the two include, but are not limited to, snap-fit ​​and / or threaded connection.

[0060] For example, the first mold core 110 is detachably fixed and embedded in the first mold body 120 by screws, and the second mold core 210 is detachably fixed and embedded in the second mold body 220 by screws.

[0061] With this design, on the one hand, different first mold cores 110 and second mold cores 210 can be disassembled and replaced, thereby defining different sealed mold cavities a between the first mold core 110 and the second mold core 210 to form products b of different shapes. On the other hand, the detachable connection method also makes it easy to replace the damaged first mold core 110 and second mold core 210.

[0062] like Figure 7 and Figure 8 As shown, in some embodiments, the injection mold 10 further includes a cutting assembly 400.

[0063] The cutting component 400 is disposed between the first mold core 110 and the first mold body 120. The first mold core 110 has a cutting hole 113, and the second mold core 210 has a cutting groove 213 corresponding to the position of the cutting hole 113. The cutting end of the cutting component 400 is adapted to pass through the cutting hole 113 to cut the cutting area 310.

[0064] In this embodiment, after product b is formed, the cutting end of the cutting component 400 passes through the cutting hole 113 to cut the cutting area 310, so that the cutting area 310 is separated from the reinforcing area 320. This design improves the production efficiency of product b compared to cutting off the cutting area 310 on the side of product b after taking product b out of the closed mold cavity a.

[0065] In actual implementation, the cutting assembly 400 may include a cylinder and a cutting blade mounted on the telescopic end of the cylinder, the cutting blade being the cutting end of the cutting assembly 400.

[0066] like Figure 7 As shown, in some embodiments, the upper mold 100 has a first cooling channel 510, which surrounds the closed mold cavity a; the lower mold 200 has a second cooling channel 520, which surrounds the closed mold cavity a.

[0067] In this embodiment, the first cooling channel 510 is arranged around the closed mold cavity a, and the second cooling channel 520 is arranged around the closed mold cavity a. This allows heat to be transferred out from the inside of the closed mold cavity a more evenly and effectively, accelerating the cooling process of product b. At the same time, uniform cooling helps to reduce uneven stress distribution inside product b caused by uneven cooling, thus avoiding deformation and cracks in product b.

[0068] like Figure 6 As shown, in some embodiments, the bottom surface of the lower mold groove 211 is provided with a through hole, and the lower mold groove 211 is provided with a receiving piece 212 suitable for closing the through hole.

[0069] When the upper mold 100 is in the second position, the through hole is used for the telescopic end of the lifting device 20 to pass through, and the telescopic end of the lifting device 20 pushes the receiving piece 212 out of the lower mold groove 211.

[0070] It should be noted that the telescopic end of the lifting device 20 directly pushes product b out, which may cause deformation of the contact area between the telescopic end of the lifting device 20 and product b.

[0071] In this embodiment, the telescopic end of the lifting device 20 contacts the receiving plate 212, and the product b is pushed out through the receiving plate 212, thus protecting the integrity of the product b.

[0072] In actual implementation, the lifting device 20 includes, but is not limited to, a cylinder.

[0073] The embodiments of this application will be described in detail below from three different implementation perspectives.

[0074] I. The injection mold 10 includes: an upper mold 100, a lower mold 200, and a reinforcing plate 300.

[0075] The upper mold 100 defines the upper mold groove 111 and the injection runner 112; The lower mold 200 defines a lower mold groove 211 corresponding to the upper mold groove 111. The upper mold groove 111 is adapted to enclose the lower mold groove 211 to form a closed mold cavity a, and the closed mold cavity a is connected to the injection flow channel 112. The reinforcing plate 300 includes a cutting area 310 and a reinforcing area 320 connected to the cutting area 310; The upper mold 100 has a first position and a second position. When the upper mold 100 is in the first position, both the upper mold 100 and the lower mold 200 abut against the cutting area 310, and the reinforcing area 320 is located in the sealed mold cavity a. When the upper mold 100 is in the second position, the upper mold 100 is separated from the cutting area 310.

[0076] In this embodiment, both the upper mold 100 and the lower mold 200 abut against the cutting area 310 of the reinforcing plate 300, thereby fixing the reinforcing area 320 of the reinforcing plate 300 in the middle of the sealed mold cavity a. After the product b is formed, the reinforcing area 320 of the reinforcing plate 300 is inside the product b. This can improve the overall strength and rigidity of the product b, and at the same time, it can prevent the reinforcing area 320 of the reinforcing plate 300 from detaching from the product b during use, thereby improving the reliability and durability of the product b.

[0077] II. The injection mold 10 also includes: a cutting component 400.

[0078] The cutting component 400 is disposed between the first mold core 110 and the first mold body 120. The first mold core 110 has a cutting hole 113, and the second mold core 210 has a cutting groove 213 corresponding to the position of the cutting hole 113. The cutting end of the cutting component 400 is adapted to pass through the cutting hole 113 to cut the cutting area 310.

[0079] In this embodiment, after product b is formed, the cutting end of the cutting component 400 passes through the cutting hole 113 to cut the cutting area 310, so that the cutting area 310 is separated from the reinforcing area 320. This design improves the production efficiency of product b compared to cutting off the cutting area 310 on the side of product b after taking product b out of the closed mold cavity a.

[0080] 3. A through hole is provided on the bottom surface of the lower mold groove 211. The lower mold groove 211 is provided with a receiving piece 212 suitable for closing the through hole. When the upper mold 100 is in the second position, the through hole is used for the telescopic end of the lifting device 20 to pass through, and the telescopic end of the lifting device 20 pushes the receiving piece 212 out of the lower mold groove 211.

[0081] It should be noted that the telescopic end of the lifting device 20 directly pushes out product b, which may cause deformation, scratches or damage to the contact area between the lifting device 20 and product b.

[0082] In this embodiment, the telescopic end of the lifting device 20 contacts the receiving plate 212, which is parallel to the bottom surface of product b. Product b is pushed out through the receiving plate 212, thus protecting the integrity of product b. like Figures 9-11 As shown, this application also proposes an injection molding system, including an injection mold 10, a lifting device 20, a positioning device 30, a material handling device, and a controller as described in any of the above embodiments.

[0083] Injection mold 10 is used to injection mold product b. Lifting device 20 is located below injection mold 10, positioning device 30 is located above injection mold 10, and material taking device is located on the side of injection mold 10. The controller is electrically connected to the lifting device 20, the positioning device 30, and the material handling device. The controller is configured to control the telescopic end of the lifting device 20 to pass through the through hole, abut against the receiving piece 212, and move upward to the third position. When the receiving piece 212 moves to the third position, the controller sequentially controls the clamping end of the positioning device 30 to clamp and fix the upper mold 100. When the telescopic end of the lifting device 20 abuts against the receiving piece 212, the controller controls the telescopic end of the lifting device 20 to move downward to the fourth position and controls the material handling device to remove the product b.

[0084] In this embodiment, the electrical connection of the lifting device 20, positioning device 30, and material handling device via the controller automates the entire injection molding process, reducing manual intervention and improving production efficiency and consistency. Furthermore, the optimized workflow reduces unnecessary waiting and repetitive actions, thereby shortening the production cycle and increasing production efficiency.

[0085] like Figure 11 As shown, in actual implementation, the injection molding system also includes: base 40.

[0086] The lifting device 20, the positioning device 30, and the material handling device are all mounted on the base 40.

[0087] like Figures 9-11 As shown, this application also proposes a control method for an injection molding system, including steps 610 and 620.

[0088] like Figure 9 As shown in step 610, the telescopic end of the control lifting device 20 passes through the through hole, abuts against the receiving piece 212, and moves upward to the third position.

[0089] In this step, if the telescopic end of the lifting device 20 directly pushes out the product b, the telescopic end of the lifting device 20 may cause deformation of the contact area with the product b. However, by contacting the receiving piece 212, the telescopic end of the lifting device 20 can push out the product b, the upper film and the first mold core 110 together, thus protecting the integrity of the product b.

[0090] like Figure 9 and Figure 10 As shown, in step 620, when the receiving piece 212 moves to the third position, the clamping end of the positioning device 30 is sequentially controlled to clamp and fix the upper mold 100. When the telescopic end of the lifting device 20 is in contact with the receiving piece 212, the telescopic end of the lifting device 20 is controlled to move down to the fourth position and the material handling device is controlled to move out of the product b.

[0091] In this step, when the telescopic end of the lifting device 20 is in contact with the receiving piece 212, the telescopic end of the lifting device 20 is controlled to move down to the fourth position. At this time, product b, upper film and first mold core 110 will move down with the telescopic end of the lifting device 20.

[0092] The fourth position can be directly below the third position, and there is a gap between the fourth position and the third position for the material handling device to remove product b.

[0093] In this embodiment, the electrical connection of the lifting device 20, positioning device 30, and material handling device via the controller automates the entire injection molding process, reducing manual intervention and improving production efficiency and consistency. Furthermore, the optimized workflow reduces unnecessary waiting and repetitive actions, thereby shortening the production cycle and increasing production efficiency.

[0094] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
