[0002] In the field of plastic workpiece production and processing, in order to make the injection-molded workpiece have higher strength and durability while meeting the requirements of light weight, in the existing injection molding process, generally, a metal insert is directly combined with the plastic part to form an integral structure during the injection molding process of the plastic workpiece. Thus, the metal insert part can reliably connect fasteners, and the overall injection-molded workpiece also has a lighter mass. This processing method combines the advantages of both plastic and metal materials, increases the product designability, and at the same time avoids using other complex processes to assemble the two together additionally, and the overall strength of the workpiece is also improved.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 As shown, this embodiment provides an injection mold 10 for integrally forming an insert 30 and a workpiece 20, including a first mold structure 100, a second mold structure 200, and a positioning component 300. The first mold structure 100 and the second mold structure 200 serve as the mold base of the injection mold 10. The positioning component 300 is used to carry the insert 30 and to drive the insert 30 to move relative to the first mold structure 100 and / or the second mold structure 200.

[0033] Specifically, please refer to Figure 1 and Figure 4 As shown, the first mold structure 100 has an insertion surface 121; the second mold structure 200 is relatively movably arranged with respect to the first mold structure 100, and the first mold structure 100 can be combined with the second mold structure 200 to form an injection cavity, and the insertion surface 121 is located in the injection cavity; the positioning component 300 is relatively movably arranged with respect to the first mold structure 100. When the first mold structure 100 and the second mold structure 200 are separated, the positioning component 300 is relatively spaced from the plane where the insertion surface 121 is located; during the process of the first mold structure 100 and the second mold structure 200 moving relatively closer, the positioning component 300 is used to drive at least a part of the insert 30 to move into the injection cavity.

[0034] Compared with the traditional injection mold 10, in the injection mold 10 of this embodiment, by providing a positioning component 300 that is movably arranged relative to the first mold structure 100, during the injection molding process, the insert 30 is carried on the positioning component 300, and at this time, the positioning component 300 is arranged at a relative interval with respect to the plane where the insertion surface 121 is located. With this arrangement, during the process of the first mold structure 100 approaching the second mold structure 200, both the insert 30 and the positioning component 300 can avoid the insertion surface 121 in the first mold structure 100, thereby preventing a collision between the insert 30 and the insertion surface 121. After the first mold structure 100 and the second mold structure 200 are combined, the positioning component 300 can drive the insert 30 into the injection cavity to achieve the integral molding process of the insert 30 and the workpiece 20.

[0035] In the injection mold 10 of this embodiment, by providing a movably positioning component 300, during the mold closing process of the first mold structure 100 and the second mold structure 200, the positioning component 300 can drive the insert 30 to move to avoid the insertion surface 121 of the first mold structure 100, thereby preventing damage to the insertion surface 121 caused by the insert 30 and / or the positioning component 300, ensuring the yield rate of the injection molded workpiece 20, with a simple structure and good use effect.

[0036] It should be noted that in this embodiment, during the process of the first mold structure 100 approaching the second mold structure 200, the positioning component 300 can be driven to move by the first mold structure 100 or the second mold structure 200, that is, driven by a separate component, and the positioning component 300 can also be driven simultaneously by both the first mold structure 100 and the second mold structure 200, as long as it can move during the process of the first mold structure 100 and the second mold structure 200 moving relatively closer; it can be understood that the positioning component 300 can also be driven by an external driving device, and this is not uniquely limited here.

[0037] In addition, the positioning component 300 can be movably connected to the first mold structure 100 or the second mold structure 200. Regardless of whether the positioning component 300 is movably connected to the first mold structure 100 or the second mold structure 200, this structure only serves as the bearing base of the positioning component 300. In other embodiments, the positioning component 300 can also be supported by other external structures, such as components for bearing the movement of the positioning component 300, bearing workpieces, etc., and this is not uniquely limited again.

[0038] Refer to Figure 1 and Figure 4 In the shown embodiment, the positioning component 300 is movably connected to the second mold structure 200, and during the process of the first mold structure 100 approaching the second mold structure 200, the first mold structure 100 is used to drive the positioning component 300 to move.

[0039] Specifically, referring to Figure 4 and Figure 5 As shown, the positioning assembly 300 includes a positioning member 310 and a connecting member 320 that are joined. The positioning member 310 is provided at one end of the connecting member 320 and is used to carry the insert 30. An abutting inclined surface 3241 is provided at the end of the connecting member 320 away from the positioning member 310, and the abutting inclined surface 3241 inclines away from the injection cavity in the direction from the first mold structure 100 to the positioning assembly 300; during the process of the first mold structure 100 approaching the second mold structure 200 relatively, the first mold structure 100 and / or the second mold structure 200 abuts against the abutting inclined surface 3241 to drive the positioning member 310 to move toward the insertion surface 121.

[0040] Referring to Figure 4 and [[ID= twelfth]] Figure 5 As shown, in this embodiment, the positioning member 310 and the abutting inclined surface 3241 are respectively located at opposite ends of the connecting member 320. During the process of the first mold structure 100 approaching the second mold structure 200, relative sliding occurs between the first mold structure 100 and the abutting inclined surface 3241, and the connecting member 320 is driven to move in the direction from the abutting inclined surface 3241 to the positioning member 310, so as to drive the insert 30 located on the positioning member 310 to move into the injection cavity. After the first mold structure 100 and the second mold structure 200 are closed, at least part of the insert 30 is located in the injection cavity, and the insert 30 and the workpiece 20 are integrally formed by injection molding.

[0041] Furthermore, referring to Figure 6 and Figure 7 As shown, the positioning assembly 300 further includes a suction member 330. The suction member 330 is provided at the end of the connecting member 320 close to the positioning member 310 and is used to adsorb the insert 30.

[0042] With this setting, on the one hand, the suction member 330 can fix the insert 30 installed on the positioning member 310 to prevent the insert 30 from shifting during the movement of the connecting member 320, and at the same time, it can also position the installation of the insert 30.

[0043] In this embodiment, the suction member 330 is a magnet, and the insert 30 is ferromagnetic. It can be understood that when the insert 30 is installed on the positioning member 310, the magnet can adsorb the insert 30 to achieve the fixing function, and during the installation process of the insert 30, the magnet can adsorb the insert 30 through magnetic force, thereby improving the installation efficiency and positioning accuracy of the insert 30.

[0044] In still other embodiments, the attracting member 330 may also be an electromagnet. After the electromagnet is energized, it can generate a magnetic force to attract the ferromagnetic insert 30. In some embodiments, the attracting member 330 may also be an element with an adsorption function such as a suction cup, and is not limited to this.

[0045] Referring to Figure 6 As shown, in this embodiment, an installation groove 3211 is formed at one end of the connecting member 320 facing the positioning member 310, and the attracting member 330 is embedded in the installation groove 3211.

[0046] With this arrangement, when installing the attracting member 330, the attracting member 330 can be received in the installation groove 3211. On the one hand, the installation of the attracting member 330 can be positioned. At the same time, since the attracting member 330 is received in the installation groove 3211, the overall structure of the positioning assembly 300 can also be made more compact.

[0047] Furthermore, the number of the attracting members 330 is multiple, and the multiple attracting members 330 are uniformly arranged along the circumferential direction of the central axis of the connecting member 320.

[0048] It can be understood that by providing multiple attracting members 330, when the insert 30 is installed on the positioning member 310, the multiple attracting members 330 can all adsorb and fix the insert 30, thereby improving the fixing effect of the positioning assembly 300 on the insert 30, further ensuring the installation accuracy of the insert 30, and preventing the insert 30 from separating from the positioning assembly 300.

[0049] Furthermore, referring to Figure 4 As shown, the positioning assembly 300 further includes a reset member 340, and the reset member 340 is used to drive the positioning member 310 to move away from the plane where the insertion surface 121 is located.

[0050] By providing the reset member 340, during the separation process of the first mold structure 100 and the second mold structure 200, the reset member 340 can drive the positioning member 310 to move away from the injection molding cavity, so that one end of the positioning member 310 away from the abutting inclined surface 3241 can be separated from the plane where the insertion surface 121 is located, thereby preventing the positioning assembly 300 from colliding with the insertion surface 121 during the mold closing process of the first mold structure 100 and the second mold structure 200.

[0051] Furthermore, the number of the reset members 340 is multiple, and the multiple reset members 340 are uniformly arranged along the circumferential direction of the central axis of the connecting member 320.

[0052] With this arrangement, after the driving force of the first mold structure 100 is removed, the multiple reset members 340 can all generate a force for driving the positioning assembly 300 to reset, so that the positioning member 310 moves away from the plane where the insertion surface 121 is located.

[0053] In this embodiment, the reset member 340 is a helical spring. In other embodiments, the reset member 340 can also be an elastic member such as a shrapnel or a hydraulic spring. In some embodiments, the reset member 340 can also be an external driving device and can drive the positioning assembly 300 to reciprocate along the direction from the abutting inclined surface 3241 to the positioning member 310.

[0054] Refer to Figure 4 and Figure 7 As shown, the connecting member 320 has a connecting portion 321, a top plate portion, and an abutting portion 324 arranged in sequence. The abutting inclined surface 3241 is provided on the side of the abutting portion 324 away from the top plate portion. One end of the reset member 340 abuts against the top plate portion, and one end of the connecting portion 321 away from the top plate portion is connected to the positioning member 310.

[0055] It can be understood that through the above settings, the connecting member 320 has a split structure, and each component can be detachably connected, which not only does not affect the processing effect, but also facilitates the assembly and maintenance of the connecting member 320. The structure is simple and the use effect is good.

[0056] Specifically refer to Figure 7 In the shown embodiment, the top plate portion includes a front top plate portion 322 and a rear top plate portion 323, and the front top plate portion 322 is detachably connected to the rear top plate portion 323. During the assembly process of the connecting member 320 in this embodiment, first, the abutting portion 324 is passed through the front top plate portion 322, and the rear top plate portion 323 is fixedly connected to the abutting portion 324. Then, the rear top plate portion 323 is connected to one end of the abutting portion 324 away from the abutting inclined surface 3241. Thus, the connecting portion 321 becomes an integral structure. When it is necessary to replace one of the components, only the corresponding component needs to be removed and a new component replaced, and the assembly and disassembly are convenient. Specifically, the detachable connection includes but is not limited to detachable connection methods such as screw connection, magnetic attraction connection, and pin connection.

[0057] Specifically, the orthographic projection of the insert 30 along the direction from the connecting member 320 to the positioning member 310 is located within the connecting member 320. In this embodiment, the positioning assembly 300 is movably connected to the second mold structure 200. When the first mold structure 100 is separated from the second mold structure 200, the positioning assembly 300 can drive the insert 30 to move in a direction away from the injection cavity and can cause the insert 30 to retract into the second mold structure 200, thereby avoiding collisions between the insert 30 and the piercing surface 121.

[0058] Refer to Figure 5 In the shown embodiment, the positioning member 310 is inserted into the insert 30. With this setting, on the one hand, it is convenient for the insert 30 to be assembled and disassembled on the positioning member 310, and at the same time, through the inlay fit, the positioning accuracy of the insert 30 can be ensured, and the specific tolerance is 0.02.

[0059] It should be noted that in this embodiment, the insertion surface 121 is perpendicular to the central axis of the connecting member 320. In other embodiments, the insertion surface 121 may also be inclined relative to the central axis of the connecting member 320.

[0060] The present application also provides an injection mold 10. It should be noted that this embodiment is improved based on any one of the above embodiments, and only the differences are listed below;

[0061] In this embodiment, the injection mold 10 further includes a bearing core 400 and a moving mechanism 500. The bearing core 400 is movably arranged relative to the second mold structure 200. The bearing core 400 can be combined with the first mold structure 100 and the second mold structure 200 to form an injection cavity; the positioning assembly 300 is arranged on the bearing core 400 and is movably connected to the bearing core 400. The positioning assembly 300 is used to carry the insert 30; the moving mechanism 500 is connected to the bearing core 400 and is used to drive the bearing core 400 to move in a direction close to or away from the injection cavity.

[0062] In the injection mold 10 provided in this embodiment, by providing a movable bearing core 400 and a moving mechanism 500 for driving the bearing core 400 to move, during the processing flow, the moving mechanism 500 can drive the bearing core 400 to move away from the injection cavity so as to install the insert 30 on the positioning assembly 300. After the insert 30 is installed, the moving mechanism 500 drives the bearing core 400 to move towards the injection cavity, so that at least part of the insert 30 moves into the injection cavity, thereby realizing one-piece forming processing.

[0063] In the injection mold 10 of this embodiment, by setting the cooperation between the bearing core 400 and the moving mechanism 500, on the premise of ensuring the installation accuracy of the insert 30, the processing efficiency of the workpiece 20 can be improved, and the first mold structure 100 and / or the second mold structure 200 can be avoided from being damaged during the installation of the insert 30. The processing effect of injection molding is ensured, the structure is simple, and the use effect is good.

[0064] Specifically refer to Figure 1 and Figure 8 As shown, the first mold structure 100 includes a first template 110 and a first core 120. The first template 110 is provided with a first receiving cavity 111 for receiving the first core 120. During the process of the first mold structure 100 approaching the second mold structure 200, the first template 110 can abut against one end of the positioning assembly 300 away from the insert 30 and is used to drive the positioning assembly 300 to move towards the injection cavity; the first core 120, the second mold structure 200, and the bearing core 400 can be combined to form an injection cavity, and the insertion surface 121 is located on the first core 120.

[0065] In this embodiment, the first template 110 can move relative to the positioning component 300. During the process of the first mold structure 100 approaching the second mold structure 200, the first template 110 can serve as a power source to drive one end of the positioning component 300 to move towards the insertion surface 121. During the movement, the positioning of the insert 30 at the corresponding position of the workpiece 20 can be achieved.

[0066] Specifically refer to Figure 8 As shown, in this embodiment, the first template 110 is provided with a spade base position 112, and the opening of the spade base position 112 is located on the inner wall of the first accommodation cavity 111. The spade base position 112 is used to drive the positioning component 300 towards the injection cavity; at least one positioning component 300 is provided, and the orthographic projections of the positioning component 300 on the spade base position 112 are all located within the spade base position 112.

[0067] Furthermore, the spade base position 112 has an abutting surface 1121, and the abutting surface 1121 is inclined away from the injection cavity along the direction from the first template 110 to the positioning component 300.

[0068] It can be understood that since the spade base position 112 has an inclined abutting surface 1121, a driving force can be applied to the positioning component 300 when the abutting surface 1121 contacts the positioning component 300. Through the mutual friction between the abutting surface 1121 and the positioning component 300, the positioning component 300 is driven to drive the insert 30 to move to a preset position.

[0069] Refer to Figure 4 As shown, specifically in this embodiment, the connecting member 320 is slidably matched with the bearing die core 400, and the reset member 340 is respectively connected to the connecting member 320 and the bearing die core 400, and is used to drive the positioning member 310 to move away from the plane where the insertion surface 121 is located.

[0070] Furthermore, the connecting member 320 has a connecting portion 321, a top plate portion, and an abutting portion 324 arranged in sequence. An abutting inclined surface 3241 is provided on the side of the abutting portion 324 away from the top plate portion. One end of the reset member 340 abuts against the top plate portion, and the end of the connecting portion 321 away from the top plate portion is connected to the positioning member 310.

[0071] Refer to Figure 2 As shown, in this embodiment, the bearing die core 400 has an abutting die core body 410 and a mounting plate 420. The die core body 410 is provided with a mounting cavity 412 for accommodating the top plate portion, and the connecting portion 321 penetrates through the die core body 410. The mounting plate 420 covers the opening at one end of the mounting cavity 412 away from the connecting portion 321, and the abutting portion 324 penetrates through the mounting plate 420; the reset member 340 is accommodated in the mounting cavity 412, and the opposite ends of the reset member 340 respectively abut against the die core body 410 and the top plate portion.

[0072] In this embodiment, the opening of the mounting cavity 412 is located on the side away from the injection cavity. When assembling the injection mold 10 of this embodiment, the positioning assembly 300 is first passed through the mounting cavity 412, and the positioning member 310 and the connecting member 320 are passed through one end of the supporting mold core 400. At this time, the top plate portion is located in the mounting cavity 412, and then the mounting plate 420 is covered on the opening of the mounting cavity 412, and the abutment portion 324 is passed through the mounting plate 420 and extends in the direction away from the injection cavity.

[0073] Specific as Figure 4 In the illustrated embodiment, a positioning groove 411 is defined within the core body 410 and communicates with the mounting cavity 412. The reset member 340 is received within the positioning groove 411. This arrangement not only positions the reset member 340 for installation, but also allows for a more compact installation of the positioning assembly 300 and the carrier core 400.

[0074] Further, see Figure 2 As shown, the supporting mold core 400 also includes a limit plate 430, which is arranged on the side of the mold core body 410 away from the injection cavity; on the moving path of the first template 110, the limit plate 430 can abut against the first template 110; specifically, the limit plate 430 is detachably connected to the mold core body 410.

[0075] It is understandable that, under normal circumstances, in order to reduce the processing error of the injection molded workpiece 20, the gap between the first mold structure 100 and the second mold structure 200 after the mold is closed needs to be as small as possible. However, due to the existence of processing errors, friction loss is inevitable between the first mold structure 100 and the load-bearing core 400. By providing a limit plate 430 on the core body 410, on the one hand, the movement of the first template 110 can be limited to prevent the first mold structure 100 from squeezing or wearing the load-bearing core 400 and causing damage to the load-bearing core 400. When the limit plate 430 is worn to a certain extent, the limit plate 430 can be easily disassembled and replaced. Preferably, the limit plate 430 is made of wear-resistant material, so that the loss of the limit plate 430 can be reduced.

[0076] See Figure 1 and Figure 2 As shown, the second mold structure 200 includes a second mold plate 210 and a second mold core 220. The second mold plate 210 defines a second accommodating cavity 211 for accommodating the second mold core 220. The second mold core 220, the first mold structure 100, and the supporting mold core 400 can be combined to form an injection cavity. The second mold core 220 is arranged opposite to the first mold structure 100, and the supporting mold core 400 is located on one side of the second mold core 220.

[0077] In this embodiment, the carrier core 400 is slidably engaged with the second mold structure 200 and can move in the positive or negative direction of the X-axis. The direction from the first mold structure 100 to the second mold structure 200 is perpendicular to the X-axis. When using the injection mold 10 of this embodiment, the moving mechanism 500 first drives the carrier core 400 to move along the X-axis. Then, the insert 30 is installed on the positioning component 300. The moving mechanism 500 then drives the carrier core 400 to move in the reverse direction of the X-axis, so that the insert 30 can move towards the injection cavity. After the carrier core 400 moves to a preset position, the first mold structure 100 moves towards the second mold structure 200. During the movement of the first mold structure 100, the first mold structure 100 can abut against the positioning component 300 and drive the positioning component 300 to move towards the injection cavity, thereby driving the insert 30 to move into the injection cavity. After the first mold structure 100 and the second mold structure 200 are closed, the insert 30 can be at least partially located in the injection cavity, and the first mold structure 100, the second mold core 220, and the carrier core 400 enclose a closed injection cavity.

[0078] It should be noted that the "closed injection cavity" described here means that the entire injection cavity is enclosed by the first mold structure 100, the second mold core 220, and the carrier core 400. However, there are also holes such as injection holes, and it is not an absolute seal.

[0079] Further, the moving mechanism 500 includes a driving component 510. The driving component 510 is respectively connected to the second mold structure 200 and the carrier core 400 and is used to drive the carrier core 400 to move relative to the second mold structure 200.

[0080] Specifically refer to Figure 3 As shown, the driving component 510 includes a linear driving member 511 and a connecting frame 512. The connecting frame 512 is connected to the carrier core 400. The linear driving member 511 is arranged on the second template 210 and is used to drive the connecting frame 512 to move so as to drive the carrier core 400 to move closer to or away from the second mold core 220.

[0081] In this embodiment, the linear driving member 511 is a hydraulic cylinder. In other embodiments, the linear driving member 511 can also be a linear driving structure such as a linear motor, an electric push rod, or a lead screw slider structure, and is not limited uniquely here.

[0082] Refer to Figure 3 As shown, in one embodiment, the connecting frame 512 includes a detachable connecting frame body 5121 and a connecting block 5122. The connecting block 5122 is connected to the output end of the linear driving member 511, and the connecting frame body 5121 is connected to the carrier core 400.

[0083] By setting the connecting frame body 5121 and the connecting block 5122 which are detachably connected, when assembling the movable mechanism 500 of this embodiment, after connecting the connecting frame body 5121 and the connecting block 5122 to the bearing die core 400 and the linear driving member 511 respectively, the two can be connected again, improving the assembly efficiency. At the same time, it is also convenient for later maintenance, with a simple structure and good use effect.

[0084] Refer to Figures 1 to 3 As shown, further, the movable mechanism 500 further includes a limiting component 520. The limiting component 520 is arranged on the second template 210 and is used to limit the movement of the bearing die core 400.

[0085] With this setting, during the movement of the bearing die core 400, the limiting component 520 can limit it, so that the bearing die core 400 can move within a preset range, avoiding damage to the injection mold 10 caused by the bearing die core 400 separating from the second mold structure 200.

[0086] Specifically, in one embodiment, the limiting component 520 includes a limit switch 521 and a sensing member 522. The limit switch 521 and the sensing member 522 are respectively arranged on the bearing die core 400 and the second template 210. On the moving path of the sensing member 522, the sensing member 522 can abut against the limit switch 521.

[0087] When using the injection mold 10 of this embodiment, the sensing member 522 can move together with the bearing die core 400. After the bearing die core 400 moves to a specified position, the sensing member 522 abuts against the limit switch 521, and the limit switch 521 controls the linear driving member 511 to stop running, thereby controlling the movement of the bearing die core 400.

[0088] Further, at least two limit switches 521 are provided, and two of the limit switches 521 are arranged at intervals along the moving direction of the bearing die core 400.

[0089] Refer to Figure 2 As shown, in this embodiment, two limit switches 521 are provided, and the two limit switches 521 are arranged in sequence along the X direction. When the bearing die core 400 moves to the end in the positive or negative direction along the X direction, the sensing member 522 can contact the corresponding limit switch 521, and the position control of the bearing die core 400 is realized; in other embodiments, by setting multiple limit switches 521, the multiple moving positions of the bearing die core 400 can be positioned.

[0090] Refer to Figure 2As shown, the limit component 520 further includes a limit frame 523, the limit frame 523 is arranged on the second template 210, on the moving path of the connecting frame 512, the connecting frame 512 can pass through the limit frame 523, and the bearing die core 400 and / or the connecting frame 512 can abut against the limit frame 523.

[0091] With this arrangement, after the bearing die core 400 moves to the extreme position, one end of the bearing die core 400 facing the limit frame 523 can abut against the limit frame 523, and the connecting frame 512 can pass out of the limit frame 523; the limit frame 523 can limit the bearing die core 400, and the limit frame 523 can also avoid movement interference with the connecting frame 512. The structure is simple and the use effect is good.

[0092] Further, referring to Figure 2 and Figure 3 as shown, the second mold structure 200 further includes a guide block 230, the guide block 230 is arranged on the second template 210, and the bearing die core 400 is in sliding fit with the guide block 230.

[0093] By arranging the guide block 230 on the second template 210, a sliding groove for accommodating the bearing die core 400 can be formed between the guide block 230 and the second template 210, and the bearing die core 400 is in sliding fit with the sliding groove, so as to guide the bearing die core 400 to enable the bearing die core 400 to slide smoothly.

[0094] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
