Technical Field

[0001] This utility model relates to the field of mold technology, specifically a modular template for injection molds that can be quickly assembled. Background Technology

[0002] Injection molds are components that give shape and size to plastic in the plastic injection molding process. They include punches, dies, and cores, which confine molten material and allow it to cool and solidify into a specific shape. Generally, one mold corresponds to one molded shape, that is, one product. Modular injection mold templates are a technology that designs the various functional parts of an injection mold as independent modules. These modules can be combined and replaced according to different production needs, allowing molds to be combined to form a variety of different products, reducing production and maintenance costs.

[0003] Chinese patent CN213440830U discloses a modular injection mold, including an upper mold plate, a lower mold plate, and multiple lower mold cores. The top surface of the lower mold plate has multiple mounting holes for mounting the lower mold cores. These mounting holes have the same structure and are arranged in an array. Each of the multiple lower mold cores corresponds to one of the mounting holes, and the lower mold cores are installed in the corresponding mounting holes. The multiple lower mold cores are divided into multiple rows along the front-back direction, and the lower mold cores in the same row are arranged along the left-right direction. The multiple lower mold cores have the same structure, and the outer edge of each of the multiple lower mold cores includes a pair of parallel positioning straight edges. The pair of positioning straight edges on the same lower mold core are symmetrically arranged from left to right, and the pair of positioning straight edges on the same lower mold core includes a left positioning straight edge and a right positioning straight edge.

Multiple through cooling channels are formed on both the first lower mold 21 and the second lower mold 22. Connecting ports 23 are fixedly installed at both ends of the cooling channels. Adjacent connecting ports 23 are connected by hoses to form a passage for cooling the first lower mold 21 and the second lower mold 22.

[0032] A third lower mold 26 is provided on the left side of the first lower mold 21, and the third lower mold 26 and the second lower mold 22 are mirror images of each other.

[0033] The module forming device 2 can be combined in various ways to form different modules, and the synchronous locking device 3 is used to quickly lock the module forming device 2.

The rotating handle 312 is fixedly mounted on one side of the shaft of the worm gear 310 for rotating the worm gear 310 for adjustment.

[0045] The rotating handle 312 of the fixed component rotates, causing the worm gear 310 to rotate. The worm gear 310 rotates, causing the worm wheel 39 to rotate. The worm wheel 39 rotates, causing the hollow rod 36 to rotate. The hollow rod 36 rotates, causing the third gear 37 to rotate. The third gear 37 rotates, causing the first gear 34 and the second gear 35 to rotate respectively. The first gear 34 rotates, causing the left and right rotating blocks 31 to rotate. The second gear 35 rotates, causing the front and rear rotating blocks 31 to rotate. The rotating blocks 31 rotate into the irregular slots 25 of the first lower mold 21 and the second lower mold 22, which is used to quickly lock the first lower mold 21 and the second lower mold 22 in the horizontal and vertical directions, which is conducive to locking the first lower mold 21 and the second lower mold 22 in one step.
