Description

Technical Field

[0001] This utility model relates to the field of molding and processing technology, and in particular to a mold. Background Technology

[0002] When using molds for molding, the workpiece (e.g., a titanium strip) is typically placed on the lower mold first. Then, the upper mold moves closer to the lower mold to close the mold, forming a sealed molding cavity. Next, molten plastic or molten metal is poured into the molding cavity to solidify onto the workpiece inside, forming the product. Finally, the upper mold moves away from the lower mold, and the molded product is removed after the mold is opened. However, the workpiece placement process in this molding process is cumbersome, leading to reduced molding efficiency. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a mold to improve molding efficiency.

[0004] This application provides a mold, including: Upper mold component; The lower mold assembly includes a lower mold core, a support member, and two forming members. The lower mold core and the upper mold assembly can be closed together. The lower mold core has a forming position. The support member is slidably disposed on the lower mold core. The two forming members are spaced apart on the support member along the sliding direction of the support member. The forming members are configured to carry the workpiece and move to the forming position under the drive of the support member, so as to cooperate with the support member, the lower mold core, and the upper mold assembly to form a forming cavity.

[0005] In actual use, the aforementioned mold works as follows: First, a workpiece is placed on one of the molding components, causing the carrier component to move the molded component carrying the workpiece to the molding position. This, along with the carrier component, lower mold core, and upper mold assembly, forms a molding cavity, allowing the workpiece to be molded into a product within the cavity. Simultaneously, another workpiece is placed on another molding component. Then, after the product is formed, the upper mold assembly moves away from the lower mold assembly, and the carrier component moves the molded component carrying the product out of the molding position, while simultaneously moving the molded component carrying the workpiece to be molded to the molding position. Finally, the upper mold assembly moves closer to the lower mold assembly, allowing the molded component, carrier component, and lower mold core to form the molding cavity. At the same time, another workpiece to be molded replaces the product on the molded component that moved out of the molding position. In this way, the mold uses two molding components to alternately move the workpieces to be molded to the molding position, effectively utilizing the time for mold closing and product forming to place the workpiece, optimizing the molding process, and improving molding efficiency.

[0006] In some embodiments, the mold further includes a guide assembly, which is disposed on one side of the lower mold core along the sliding direction of the carrier and connected to the lower mold core.

The guide groove is formed between the two guide bodies. Each guide body has an extension at one end away from the third groove wall. The extension is used to abut against the upper surface of the carrier.

[0012] In some embodiments, the molded part includes: A support body is embedded in and detachably connected to the carrier. The support body has a support position, a sliding groove, and a receiving groove. The support position is configured to support the workpiece. The sliding groove is inclined relative to the mold opening direction and is located adjacent to the support position.

A second elastic body is disposed in the receiving groove; and The clamping body is slidably disposed in the sliding groove and abuts against the two ends of the second elastic body, respectively, with the bottom of the receiving groove. The clamping body is configured to push the workpiece under the drive of the second elastic body, so that the workpiece abuts against the reference body and the abutting body, respectively.

[0013] In some embodiments, the lower mold core is provided with a through groove, an opening, and a guide groove.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0026] Please see Figure 1 This application provides a mold 100, which includes an upper mold assembly 110 and a lower mold assembly 120, for molding products to improve molding efficiency.

[0027] Please see Figure 1 and Figure 2 The lower mold assembly 120 includes a lower mold core 10, a support member 20, and two molding members 30. The lower mold core 10 and the upper mold assembly 110 can be closed together. The lower mold core 10 is provided with a molding position 14. The support member 20 is slidably disposed on the lower mold core 10. The two molding members 30 are spaced apart on the support member 20 along the sliding direction of the support member 20. The molding members 30 are configured to support the workpiece and move to the molding position 14 under the drive of the support member 20, so as to cooperate with the support member 20, the lower mold core 10, and the upper mold assembly 110 to form a molding cavity (not shown in the figure).

[0028] In actual use, the mold 100 described above first places a workpiece on one of the molding parts 30, so that the carrier 20 moves the molding part 30 carrying the workpiece to the molding position 14, so that the carrier 20, the lower mold core 10 and the upper mold assembly 110 can surround and form a molding cavity, so that the workpiece is formed into a product in the molding cavity. At the same time, another workpiece is placed on another molding part 30. Then, after the product is formed, the upper mold assembly 110 moves away from the lower mold assembly 120, and the carrier 20 moves the molding part 30 carrying the product out of the molding position 14, and moves the molding part 30 carrying the workpiece to be formed to the molding position 14. Finally, the upper mold assembly 110 moves closer to the lower mold assembly 120, so that the molding part 30, the carrier 20 and the lower mold core 10 that have moved to the molding position 14 can surround and form a molding cavity. At the same time, another workpiece to be formed replaces the product on the molding part 30 that has moved out of the molding position 14. In this way, the mold 100 uses two molding parts 30 to move the workpiece to be molded alternately to the molding position 14, making reasonable use of the time for mold closing and product molding to place the workpiece, thus optimizing the molding process and improving molding efficiency.

[0029] It should be noted that the mold 100 injects molten plastic into the molding cavity, so that the plastic solidifies on the periphery of the workpiece in the molding cavity, thus forming a product.

[0030] Please see Figure 1 In some embodiments, the mold 100 further includes a guide assembly 130. The guide assembly 130 is disposed on one side of the lower mold core 10 and connected to the lower mold core 10 along the sliding direction of the support member 20. The guide assembly 130 is provided with a guide groove 41, which extends along the movement direction of the support member 20. The guide groove 41 is configured to receive the support member 20 and guide the support member 20 to move to the forming position 14.

[0031] Thus, by setting the aforementioned guide component 130, the guide groove 41 can guide the movement direction of the carrier 20, enabling the carrier 20 to accurately move the molded part 30 to the molding position 14, thereby improving the molding accuracy.

[0032] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, the guide assembly 130 includes a guide member 40 and a bearing member 50. The guide member 40 is connected to the lower mold core 10 and has a guide groove 41. The guide groove 41 includes a first groove wall 411, a second groove wall 412, and a third groove wall 413. The first groove wall 411 and the second groove wall 412 are arranged opposite each other in a direction perpendicular to the direction of movement of the carrier member 20. The third groove wall 413 is connected to the first groove wall 411 and the second groove wall 412 respectively. The bearing member 50 is disposed on the first groove wall 411 or the second groove wall 412 and is rotatably connected to the guide member 40. The bearing member 50 is configured to abut against the side wall of the carrier member 20 located in the guide groove 41. Exemplarily, the bearing member 50 can be a bearing.

[0033] Thus, by setting the specific structure of the guide component 130, the bearing component 50 can prevent the carrier component 20 from directly contacting the groove wall of the guide groove 41, allowing the carrier component 20 to slide smoothly, reducing the wear of the guide component 40 and the carrier component 20, and improving the service life of the mold 100.

[0034] Please see Figure 2 Specifically, there are two guide members 40. The two guide members 40 are respectively located on both sides of the lower mold core 10 along the sliding direction of the support member 20 and are respectively connected to the lower mold core 10. Each guide member 40 has a guide groove 41. In this way, by setting two guide members 40, the guiding distance of the guide assembly 130 to the support member 20 can be increased, ensuring that the support member 20 can move to the forming position 14 under the guidance of either guide member 40.

[0035] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, both the first groove wall 411 and the second groove wall 412 are provided with multiple bearing components 50, which are spaced apart along the movement direction of the carrier 20. In this way, by providing multiple bearing components 50, it is possible to stably separate the carrier 20 from the first groove wall 411 and the second groove wall 412, and avoid contact between the carrier 20 and the first groove wall 411 and the second groove wall 412.

[0036] Please see Figure 1 and Figure 3 In some embodiments, the first groove wall 411 or the second groove wall 412 is provided with a receiving groove 42, and the bearing member 50 is rotatably disposed in the receiving groove 42 and extends out of the receiving groove 42.

[0037] Thus, through the above arrangement, the guide component 40 and the bearing component 50 can be reasonably arranged, reducing the space occupied by the guide assembly 130.

[0038] In this embodiment, both the first groove wall 411 and the second groove wall 412 are provided with multiple receiving grooves 42, and the multiple receiving grooves 42 correspond one-to-one with multiple bearing components 50.

[0039] Please see Figure 1 In some embodiments, the guide assembly 130 further includes an elastic element 60. The elastic element 60 is disposed on the third groove wall 413 and connected to the guide 40, and the elastic element 60 is used to elastically support the carrier 20.

[0040] Thus, through the above-mentioned arrangement, the elastic element 60 can provide elastic support for the carrier 20, preventing the carrier 20 from abutting against the bottom of the guide groove 41 after the workpiece is clamped, thereby increasing the friction force on the carrier 20 and ensuring that the carrier 20 slides smoothly. In addition, when the carrier 20 is subjected to external interference or uneven force, the carrier 20 compresses the elastic element 60 to adjust its orientation and position, ensuring that the carrier 20 stably supports the workpiece and drives the workpiece to move, further improving the molding quality.

[0041] In this embodiment, there are multiple elastic elements 60, which are spaced apart along the movement direction of the support member 20. Thus, by providing multiple elastic elements 60, they can abut against different positions on the support member 20, thereby increasing the elastic support force on the support member 20.

[0042] Please see Figure 1 and Figure 3In some embodiments, the elastic element 60 includes a fixing body 61, a connecting body 62, and a first elastic body 63. The fixing body 61 is disposed on the third groove wall 413 and connected to the guide member 40, and the fixing body 61 has a receiving groove 611. The connecting body 62 passes through the receiving groove 611 and extends out of the receiving groove 611, and the first elastic body 63 is disposed in the receiving groove 611, with its two ends elastically abutting against the connecting body 62 and the bottom of the receiving groove 611, respectively. Exemplarily, the first elastic body 63 can be a spring.

[0043] Thus, through the above settings, the supporting force provided by the elastic element 60 can be flexibly adjusted according to the different weights and motion states of the carrier 20, ensuring that the elastic element 60 stably supports the carrier 20 and avoids the carrier 20 from contacting the bottom of the guide groove 41.

[0044] Please see Figure 3 Specifically, the connecting body 62 includes a connecting part 621 and a bearing part 622. The connecting part 621 is movably inserted through the receiving groove 611 and abuts against the first elastic body 63. The bearing part 622 is rotatably connected to the connecting part 621 and extends out of the receiving groove 611. The bearing part 622 rolls against the lower surface of the bearing member 20.

[0045] Thus, through the above arrangement, the connecting body 62 forms a rolling contact with the carrier 20 through the bearing part 622, reducing the friction between the carrier 20 and the connecting body 62, and ensuring that the carrier 20 slides smoothly.

[0046] Please see Figure 1 and Figure 3 In some embodiments, each guide member 40 includes two guide bodies 43, which are spaced apart in the direction perpendicular to the sliding direction of the carrier member 20 and located on the same side of the lower mold core 10. A guide groove 41 is formed between the two guide bodies 43. Each guide body 43 has an extension 431 at one end away from the third groove wall 413. The extension 431 is used to abut against the upper surface of the carrier member 20.

[0047] Thus, through the above-mentioned arrangement, the extension 431 abuts against the upper surface of the support member 20, which can limit the support member 20 along the mold opening direction, prevent the support member 20 from swinging up and down during the sliding process, so as to ensure the movement stability of the support member 20 and improve the molding quality.

[0048] Please see Figure 1 , Figure 4 and Figure 5In some embodiments, the molded part 30 includes a support body 31, a reference body 32, an abutment body 33, a second elastic body 34, and a clamping body 35. The support body 31 is embedded in and detachably connected to the carrier 20. The support body 31 has a support position 311, a sliding groove 312, and a receiving groove 313. The support position 311 is configured to support the workpiece. The sliding groove 312 is inclined relative to the mold opening direction and is located adjacent to the support position 311. The receiving groove 313 is located at the bottom of the sliding groove 312, and its extension direction is parallel to the mold opening direction. The reference body 32 is located adjacent to the support position 311 and connected to the support body 31. The abutment body 33 is located on one side of the support position 311 and connected to the support body 31. The setting direction of the abutment body 33 is perpendicular to the setting direction of the reference body 32. The second elastic body 34 is disposed in the receiving groove 313, and the clamping body 35 is slidably disposed in the sliding groove 312, and abuts against the bottom of the receiving groove 313 at both ends of the second elastic body 34. The clamping body 35 is configured to push the workpiece under the drive of the second elastic body 34, so that the workpiece abuts against the reference body 32 and the abutment body 33 respectively. For example, the second elastic body 34 can be a spring.

[0049] Thus, with the above configuration, when the workpiece is placed in the support position 311, the clamping body 35 pushes the workpiece under the drive of the second elastic body 34, so that the workpiece abuts against the reference body 32 and the abutment body 33 respectively, so that the clamping body 35 cooperates with the reference body 32 and the abutment body 33 to clamp and fix the workpiece, thereby positioning the workpiece to the support position 311, preventing the workpiece from shaking or shifting during the movement driven by the carrier 20, thereby improving the forming accuracy.

[0050] Please see Figure 1 and Figure 6 In some embodiments, the lower mold core 10 is provided with a through groove 11, an opening 13, and a guide groove 12. The through groove 11 extends through the lower mold core 10 along the sliding direction of the support member 20 and is configured to receive and guide the support member 20. The opening 13 is located at the forming position 14 and is provided on the side of the lower mold core 10 facing the upper mold assembly 110. The opening 13 communicates with the through groove 11 and is configured to avoid the formed member 30 displaced to the forming position 14. The guide groove 12 is located on one side of the opening 13 and is provided on the side of the lower mold core 10 facing the upper mold assembly 110. The guide groove 12 communicates with the opening 13, and the groove wall of the guide groove 12 away from the through groove 11 is provided with a guide slope 121. It should be noted that the through groove 11 is connected to the guide groove 41.

[0051] Thus, through the above-mentioned arrangement, the through groove 11 guides the movement direction of the support member 20, ensuring that the support member 20 is accurately molded to position 14, thereby improving molding accuracy. The opening 13 can prevent the molded part 30 from moving to the molding position 14, ensuring that the molded part 30 cooperates with the support member 20, the lower mold core 10 and the upper mold assembly 110 to form a molding cavity. The guide groove 12 guides the upper mold assembly 110 through the guide slope 121, so that the upper mold assembly 110 and the lower mold assembly 120 are accurately molded together, while reducing the resistance and error of the mold 100 during the mold closing process, thereby improving molding accuracy and stability.

[0052] Please see Figure 1 and Figure 6 In some embodiments, the wall of the through groove 11 is provided with a retaining slope 111. The retaining slope 111 is located near the opening 13. The side wall of the support member 20 is provided with a matching slope 21 on the side facing the retaining slope 111. The matching slope 21 is used to abut against the retaining slope 111 when the mold is closed.

[0053] Thus, through the above arrangement, when the mold is closed, the upper mold assembly 110 moves close to the support member 20 and presses against the support member 20, so that the support member 20 moves close to the bottom of the guide groove 41, so that the adapting inclined surface 21 of the support member 20 abuts against the holding inclined surface 111 to seal the gap between the support member 20 and the lower mold core 10, preventing molten plastic from leaking out from between the support member 20 and the lower mold core 10, thereby improving the molding quality.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
