Technical Field

[0001] The utility model relates to the technical field of polymer injection molding molds, in particular to a mold foot component based on a polymer injection molding mold and a device thereof. Background Art

[0002] In the field of injection molding production, plastic is an important organic synthetic polymer material. Injection molding technology can be used to mass-produce plastic products with complex structures and specific shapes and sizes. For example, plastic products around electronic products include common button knobs, plastic brackets, panels or back covers, etc. The above plastic products require the use of injection molds to complete injection molding.

[0003] Among them, during the production and transportation of the matching molds of the above-mentioned plastic products, it is necessary to install mold feet on the periphery of the mold to support the dry placement of the mold to facilitate the later use and maintenance of the mold. However, the traditional mold foot installation is to directly lock one end of the cylindrical mold foot on the mold. Although the cylindrical mold foot is easy to install, the other end of the cylindrical mold foot has a small grounding area. Therefore, it is easy for workshop production personnel or other transportation equipment to accidentally hit the mold, causing the mold to be more likely to roll over and cause safety accidents.

[0033] The present invention provides a mold foot assembly based on a polymer injection molding mold, comprising a mold foot body and a grounding support. One end of the mold foot body is connected to the mold foot mounting hole of the mold. The grounding support is formed with a connecting mounting portion and a grounding support portion perpendicular to each other, the connecting mounting portion is detachably connected to the outer peripheral wall of the other end of the mold foot body, and the grounding support portion is formed with an anti-skid and wear-resistant support surface, and the anti-skid and wear-resistant support surface is flush with the end surface of the other end of the mold foot body.

[0034] See also Figures 1 to 5 In order to better understand the mold foot assembly 10 based on the polymer injection molding mold of the present application, the mold foot assembly 10 based on the polymer injection molding mold is further explained below:

[0035] A mold foot assembly 10 based on a polymer injection molding mold in one embodiment includes a mold foot body 100 and a ground support 200. One end of the mold foot body 100 is connected to the mold foot mounting hole 401 of the mold. The ground support 200 is formed with a mutually perpendicular connecting mounting portion 210 and a ground support portion 220, the connecting mounting portion 210 is detachably connected to the outer peripheral wall of the other end of the mold foot body 100, and the ground support portion 220 is formed with an anti-skid and wear-resistant support surface 2210, and the anti-skid and wear-resistant support surface 2210 is flush with the other end surface of the mold foot body 100.

[0036] In this embodiment, the mold foot assembly 10 based on the polymer injection molding mold can increase the number of grounding supports 200 so that the anti-slip and wear-resistant support surface 2210 of the grounding support 200 can effectively increase the grounding area of ​​the other end of the mold foot body 100, and at the same time improve the overall grounding friction of the other end of the mold foot body 100, so that the mold foot body 100 can provide stable and reliable support and anti-slip effect for the mold, thereby making the mold have better stability, which effectively prevents production personnel or other transportation equipment from colliding with the mold and causing it to roll over, thereby causing safety accidents.

[0037] like Figure 1 and Figure 4 As shown, in one embodiment, a structural reinforcement rib 2110 is welded between the connection mounting portion 210 and the ground support portion 220. In one embodiment, the outer peripheral wall of the mold body 100 is surrounded by a gripping recess 110, and the gripping recess 110 is covered with a gripping rubber sleeve 500.

[0038] It can be understood that by welding the structural reinforcement rib 2110 between the connection and installation part 210 and the ground support part 220, the structural strength of the vertical connection between the connection and installation part 210 and the ground support part 220 can be significantly improved, that is, the ground support 200 has better structural strength support. And through the combination of the gripping recess 110 and the gripping rubber sleeve 500, it is convenient for production personnel to hold the mold foot body 100 for corresponding installation, disassembly and transportation, that is, the mold foot body 100 is more operable.

[0039] like Figure 4 As shown, in one embodiment, the outer peripheral wall of the other end of the mold body 100 is provided with a positioning groove 101 and a guide groove 102 that are connected in sequence. The connecting and mounting portion 210 is provided with a slide bar 2120, and the connecting and mounting portion 210 is located in the positioning groove 101, and the slide bar 2120 is slidably connected to the guide groove 102. In one embodiment, the connecting and mounting portion 210 is screwed or clamped to the positioning groove 101.

[0040] It can be understood that the convex strip of the connecting and mounting part 210 is slidably connected to the guide groove 102, ensuring the parallelism of the connecting and mounting part 210 and the central axis of the mold foot body 100, and because the connecting and mounting part 210 and the grounding support part 220 are perpendicular to each other, it can effectively ensure that the anti-skid and wear-resistant support surface 2210 of the grounding support part 220 is flush with the other end surface of the mold foot body 100, so that the grounding area of ​​the other end of the mold foot body 100 can be increased, and the flatness of the grounding surface can be ensured. Among them, in this embodiment, the connecting and mounting part 210 and the positioning groove 101 are connected by screws or buckles, which is convenient, reliable and has good operability.

[0041] like Figures 1 to 3 As shown, in one embodiment, a butt joint 120 is formed at one end of the mold foot body 100, and a positioning block 1210 is distributed on the outer peripheral wall of the butt joint 120, and the positioning block 1210 is formed with a guiding inclined surface 1211, and the number of the positioning block 1210 is at least one. In one embodiment, the mold foot mounting hole 401 includes a clearance hole 401a and a butt joint hole 401b that are connected in sequence; one end portion of the mold foot body 100 is located in the clearance hole 401a, and the butt joint 120 is arranged in the butt joint hole 401b, and a positioning notch 401c matching the positioning block 1210 is opened on the inner peripheral wall of the butt joint 401b.

[0042] It can be understood that by arranging the docking head 120 in the docking hole 401b, the positioning block 1210 and the positioning recess 401c can be quickly matched and docked, thereby improving the installation efficiency of the mold foot body 100 and the mold.

[0043] like Figure 1 and Figure 5 As shown, in one embodiment, a countersunk hole 103 is provided on one end face of the mold foot body 100, and a second threaded connection hole 1201 is provided on the end face of the docking joint 120, and the second threaded connection hole 1201 is connected to the bottom of the countersunk hole 103; a first threaded connection hole is provided at the bottom of the docking hole 401b. In one embodiment, the mold foot assembly 10 based on the polymer injection molding mold further includes a fastening screw 300, one end of which is formed with an external thread, and one end of the fastening screw 300 is screwed to the second threaded connection hole 1201 and the first threaded connection hole in sequence through the countersunk hole 103.

[0044] It can be understood that by quickly matching and docking the positioning block 1210 with the positioning recess 401c, and then using the fastening screw 300 to lock the mold foot body 100 to the mold foot mounting hole 401 of the mold, the mold foot assembly 10 based on the polymer injection molding mold can be quickly and reliably installed and connected.

[0045] like Figure 1 As shown, in one embodiment, the ground support member 200 is an integrally formed structure. In one embodiment, the mold base body 100 is an integrally formed structure.

[0046] It is understandable that the mold foot assembly 10 based on the polymer injection molding mold needs to have a good load-bearing effect, so it is necessary to adopt an integrated molded structure of the ground support 200 and the mold foot body 100, which is also convenient for the production of the ground support 200 and the mold foot body 100.

[0047] The present application also provides a mold foot device, including a mold foot assembly 10 based on a polymer injection molding mold as described in any of the above embodiments.

[0048] In this embodiment, the mold foot assembly based on the polymer injection molding mold can increase the number of grounding supports so that the anti-slip and wear-resistant supporting surface of the grounding support can effectively increase the ground contact area of ​​the other end of the mold foot body, and at the same time improve the overall grounding friction of the other end of the mold foot body, so that the mold foot body can provide stable and reliable support and anti-slip effect for the mold, thereby making the mold have better stability, which effectively prevents production personnel or other transportation equipment from colliding with the mold and causing it to roll over, thereby causing safety accidents.

[0049] Compared with the prior art, the utility model has at least the following advantages:

[0050] The mold foot assembly based on the polymer injection molding mold can increase the number of grounding supports so that the anti-slip and wear-resistant supporting surface of the grounding support can effectively increase the grounding area of ​​the other end of the mold foot body, and at the same time improve the overall grounding friction of the other end of the mold foot body, so that the mold foot body can provide stable and reliable support and anti-slip effect for the mold, thereby making the mold have better stability, which effectively prevents production personnel or other transportation equipment from colliding with the mold and causing rollover, thereby causing safety accidents.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
