Description

Technical Field

[0001] This application relates to the field of injection molding, and more particularly to an injection mold and injection molding equipment. Background Technology

[0002] Injection molds, as key process equipment for molding plastic products, are widely used in the automotive, electronics, and home appliance industries. In traditional injection molds, the core, as an important component of the molded plastic part's internal cavity or special structure, is usually fixed to the mold body by bolts, pins, or other means. This type of fixing method makes the disassembly process cumbersome and time-consuming when the core needs to be replaced or repaired, severely impacting production efficiency. Especially in multi-variety, small-batch production models, frequent core replacements lead to increased equipment downtime and significantly higher production costs. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an injection mold and injection equipment.

The mold body is provided with a first driving member on the side opposite to the mounting groove along the first direction. The core is provided with a positioning hole corresponding to the positioning post on the side facing the positioning post. The first driving member is used to drive the positioning post to extend into or disengage from the positioning hole.

[0005] Furthermore, the end of the positioning post opposite to the first driving member is provided with a guide surface.

The core is provided with a first protruding edge corresponding to the sliding groove on both sides along the third direction. The first protruding edge is slidably disposed in the sliding groove.

[0008] Furthermore, the cross-sectional shape of the groove is any one of rectangle, trapezoid, or triangle.

[0009] Furthermore, the core is provided with a second protruding edge on one side along the first direction, the second protruding edge is connected to the first protruding edge, and the second protruding edge extends through the entrance of the mounting groove to the outside of the mold body.

[0010] Furthermore, guide grooves extending along the third direction are provided on both the second and third surfaces. A locking block is slidably disposed in the guide groove. A second driving member is provided on the side of the mold body along the third direction and is connected to the locking block in a transmission manner. A locking groove is provided on the side of the first protruding edge facing the locking block. The second driving member is used to drive the locking block to extend into or disengage from the locking groove.

[0011] Furthermore, the locking groove has a first inclined surface, and the locking block has a second inclined surface corresponding to the first inclined surface.

[0012] Furthermore, the fourth surface is provided with a clearance groove along the first direction, the clearance groove forming a channel connecting the mounting groove and the outside of the mold body.

[0013] This application also provides an injection molding apparatus, including the injection mold described in any one of the above-mentioned methods.

[0014] This application achieves rapid installation and disassembly of the core by slidably setting the core in the mounting groove of the mold body and using the first driving component to drive the positioning pin to extend into or disengage from the positioning hole on the core.

[0024] This application provides an injection mold having a first direction X, a second direction Z, and a third direction Y arranged perpendicularly to each other. Specifically, the injection mold includes a mold body 100, a core 200, and at least one positioning post 300. The mold body 100 has an installation groove 101 communicating with the outside along the first direction X, and the installation groove 101 has an entrance along the first direction X. The core 200 is slidably disposed in the installation groove 101. At least one positioning post 300 is slidably connected to the mold body 100 along the second direction Z. A first driving member 310 is provided on the side of the mold body 100 facing away from the installation groove 101 along the first direction X. The side of the core 200 facing the positioning post 300 has a positioning hole 201 corresponding to the positioning post 300. The first driving member 310 is used to drive the positioning post 300 to extend into or disengage from the positioning hole 201.

[0025] Please see Figure 1 and Figure 2 as well as Figure 4As shown, in order to quickly install and remove the core 200, the mold body 100 has an installation groove 101 along the second direction Z, and the installation groove 101 is connected to the outside along one side of the first direction X to form an entrance. This entrance is used for the installation and removal of the core 200. Specifically, when the core 200 needs to be installed, the core 200 slides into the installation groove 101 through the entrance. After the core 200 slides into the preset position, the first driving component 310 is activated to drive the positioning pin 300 to move toward the core 200, thereby causing the locking block 400 to at least partially penetrate into the positioning hole 201, thereby limiting the core 200 in the first direction X and the third direction Y. The core 200 slides in the installation groove 101 to achieve the second direction Z limitation, thereby preventing the core 200 from falling out of the installation groove 101 and achieving quick installation.

[0026] It is understandable that the shape of the mounting groove 101 is adapted to the core 200. During installation, if the core 200 cannot slide within the mounting groove 101, it can be determined that the core 200 has reached the predetermined position.

[0027] Furthermore, if it is necessary to disassemble the core 200 to separate it from the mold body 100, it is only necessary to drive the positioning pin 300 out of the positioning hole 201 through the first driving component 310, thereby releasing the restriction on the core 200. At this time, it is only necessary to slide the core 200 out of the mounting groove 101 from the entrance of the mounting groove 101, thereby realizing the disassembly of the core 200.

[0028] In this embodiment, the core 200 is slidably connected to the mold body 100 to be installed in the mounting groove 101, and the positioning pin 300 is driven by the first driving member 310 to extend into or disengage from the positioning hole 201 to limit and fix the core 200, thereby realizing the installation and disassembly of the core 200, which greatly reduces the replacement time of the core 200 and the downtime of the injection molding machine. Furthermore, the mold provided in this application only requires the replacement of different cores 200, without the need to replace the entire mold.

[0029] For example, the first driving component 310 can be a linear drive module such as a cylinder, hydraulic cylinder, or electric cylinder; the specific type is not limited here.

[0030] In some embodiments, the end of the positioning post 300 opposite to the first driving member 310 is provided with a guide surface (not shown in the figure).

[0031] In one embodiment, in order to make it easier for the positioning post 300 to enter the positioning hole 201, a guide surface is provided on the periphery of the end face of the positioning post 300 facing the core 200. The guide surface can be an inclined guide surface or a circular arc guide surface, so that a section of the end face of the positioning post 300 has a diameter smaller than the diameter of the positioning hole 201, making it easier for the positioning post 300 to enter the positioning hole 201.

[0032] In another embodiment, a guide surface can be provided around the opening of the positioning hole 201 toward the positioning post 300. The guide surface can be an inclined guide surface or an arc guide surface, so that the opening diameter of the positioning hole 201 toward the positioning post 300 is larger than the diameter of the positioning post 300, thereby making it easier for the positioning post 300 to enter the positioning hole 201.

[0033] In this embodiment, both the positioning post 300 and the positioning hole 201 are circular.

[0034] In some embodiments, the core 200 is flush with the mold body 100 along the first direction X.

[0035] In some embodiments, the mounting groove 101 has a first surface 1011 along the second direction Z, a second surface 1012 and a third surface 1013 on both sides along the third direction Y, and a fourth surface 1014 along the first direction X. Sliding grooves 102 are provided on both the second surface 1012 and the third surface 1013. The core 200 has a first protruding edge 210 on both sides along the third direction Y that corresponds to the sliding groove 102. The first protruding edge 210 is slidably disposed in the sliding groove 102.

[0036] See Figure 2 As shown, since the mounting groove 101 has an inlet and is opened on the surface of the mold body 100 along the second direction Z, the mounting groove 101 has four surfaces. Specifically, the four surfaces are a first surface 1011, a second surface 1012, a third surface 1013, and a fourth surface 1014 that are connected to each other. The second surface 1012 and the third surface 1013 are located on both sides of the first surface 1011 along the third direction Y and are arranged opposite to each other. In order to enable the core 200 to be slidably disposed in the mounting groove 101, a sliding groove 102 is opened on both the second surface 1012 and the third surface 1013. Similarly, a first protruding edge 210 corresponding to the sliding groove 102 is provided on both sides of the core 200 along the third direction Y. The first protruding edge 210 can be slidably disposed in the sliding groove 102, thereby realizing the sliding of the core 200. Since the first protruding edge 210 extends into the sliding groove 102, the sliding groove 102 provides a limit for the first protruding edge 210 in the second direction Z.

[0037] In this embodiment, after the core 200 slides into the mounting groove 101 through the first protruding edge 210 and the sliding groove 102, when the end face of the core 200 away from the entrance of the mounting groove 101 touches and abuts the fourth surface 1014, it can be determined that the core 200 has moved to the predetermined position.

[0038] For example, the cross-sectional shape of the groove 102 is any one of rectangle, trapezoid, or triangle.

[0039] In this embodiment, the cross-sectional shape of the groove 102 is rectangular.

[0040] In some embodiments, the core 200 is provided with a second protruding edge 220 on one side along the first direction X. The second protruding edge 220 is connected to the first protruding edge 210 and extends through the inlet of the mounting groove 101 to the outside of the mold body 100.

[0041] like Figure 3 , Figure 4 as well as Figure 5 As shown, when disassembling the core 200, in order to provide a force point for the robotic arm or tool used to disassemble the core 200, a second protruding edge 220 is provided on the end face of the core 200 away from the relief groove 104, and the second protruding edge 220 extends at least partially to the outside of the mold body 100, so that the robotic arm or tool can drive the core 200 to enter or leave the mounting groove 101 through the second protruding edge 220 to achieve installation and disassembly.

[0042] In some embodiments, guide grooves 103 extending in the third direction Y are provided on both the second surface 1012 and the third surface 1013. A locking block 400 is slidably disposed in the guide groove 103. A second driving member 410 is provided on the side of the mold body 100 along the third direction Y and is connected to the locking block 400 in a transmission manner. A locking groove 202 is provided on the side of the first protruding edge 210 facing the locking block 400. The second driving member 410 is used to drive the locking block 400 to extend into or disengage from the locking groove 202.

[0043] Due to errors in the production and processing, there may be gaps between the positioning pin 300 and the positioning hole 201 after assembly, causing the core 200 to wobble relative to the mold body 100. Since there are also errors in the processing of the first protruding edge 210 and the slide groove 102, there may also be gaps between the first protruding edge 210 and the slide groove 102 after assembly, which will further cause the core 200 to wobble relative to the mold body 100.

[0044] See Figure 2 , Figure 3 , Figure 6 as well as Figure 7As shown, in order to prevent the core 200 from shaking relative to the mold body 100, guide grooves 103 are provided on both the second surface 1012 and the third surface 1013, and locking blocks 400 are slidably arranged in the guide grooves 103. Then, a second driving member 410 is fixedly installed on the outer wall of the mold body 100 to drive the locking block 400 to slide in the guide grooves 103. The second driving member 410 abuts against the core 200 to fix the core 200. Furthermore, in order to ensure that the locking block 400 abuts against the core 200, a locking groove 202 adapted to the locking block 400 is provided on the first protruding edge 210. That is, the locking block 400 extends into the locking groove 202 and gives the core 200 a fixing force to prevent the core 200 from shaking.

[0045] Understandably, the two locking blocks 400 provide a resisting force to both sides of the core 200 along the third direction Y to prevent the core 200 from shaking relative to the mold body 100.

[0046] It is understandable that the positioning pin 300 extends into the positioning hole 201, the first protruding edge 210 slides into the slide groove 102, and the locking block 400 abuts against the core 200, thereby limiting and fixing the position of the core 200.

[0047] For example, the second drive unit 410 can be a linear drive module such as a cylinder, hydraulic cylinder, or electric cylinder; the specific type is not limited here.

[0048] In some embodiments, the locking groove 202 has a first inclined surface 2021, and the locking block 400 has a second inclined surface 401 corresponding to the first inclined surface 2021.

[0049] See Figure 3 , Figure 4 as well as Figure 6 As shown, in order for the locking block 400 to fully apply force to the core 200, the surfaces of the locking groove 202 and the locking block 400 that abut against each other are inclined surfaces. That is, the surface of the locking groove 202 and the locking block 400 that abuts against each other is the first inclined surface 2021, and the surface of the locking block 400 and the locking groove 202 that abuts against each other is the second inclined surface 401. The two are fully combined to realize the transmission of force.

[0050] In some embodiments, the fourth surface 1014 is provided with a clearance groove 104 along the first direction X. The clearance groove 104 forms a channel communicating between the mounting groove 101 and the outside of the mold body 100. A connecting plate 500 is provided on the side of the mold body 100 away from the entrance of the mounting groove 101. A first quick connector 230 is provided on the side of the core 200 facing the connecting plate 500. A second quick connector 510 corresponding to the first quick connector 230 is provided on the side of the connecting plate 500 facing the core 200.

[0051] See Figure 5and Figure 7 As shown, since the injection-molded parts on the core 200 need to be cooled, the core 200 has a cooling channel. In order to provide coolant to the cooling channel, the inlet and outlet of the cooling channel are provided with a first quick connector 230. Correspondingly, the connecting plate 500 is also provided with a second quick connector 510 corresponding to the two first quick connectors 230. That is, one of the two second quick connectors 510 is the inlet and the other is the outlet, which is set to correspond to the first quick connector 230. The first quick connector 230 and the second quick connector 510 are connected at the clearance groove 104.

[0052] Understandably, when the core 200 contacts the fourth surface 1014, the first quick connector 230 will automatically connect to the second quick connector 510 to provide coolant to the cooling channel. When the core 200 needs to be disassembled, the first quick connector 230 and the second quick connector 510 can be manually separated, or a connector that can automatically separate and connect can be selected to achieve automatic connection and automatic separation between the first quick connector 230 and the second quick connector 510.

[0053] For example, the connection between the first quick connector 230 and the second quick connector 510 can be made using a quick-connect connector (such as a PU connector) or other types of connectors, which are not limited here.

[0054] This embodiment also provides an injection molding device, which includes an injection mold according to any one of the above.

[0055] It is understandable that, since injection molding equipment includes any of the above-mentioned injection molds, the injection molding equipment includes injection molds, which has the technical effect of this.
