[0002] In the field of injection mold manufacturing, with the continuous improvement of product complexity and production efficiency requirements, especially for products that require a large number of injection mold cavities, mold design and manufacturing face many challenges. In the structure of existing injection molds, when the number of mold cavities increases, the arrangement space of the mold often becomes messy, which not only increases the difficulty of mold design, but also directly leads to the complication of runner design and a significant increase in runner length. Specifically:

[0003] In multi-cavity injection molds, in order to accommodate more cavities, the arrangement of the molds often has to sacrifice a certain amount of space optimization, resulting in uneven spacing between cavities and complex flow channel layout. This chaotic arrangement not only increases the complexity of mold processing, but also limits the standardization and modular design of the mold, which is not conducive to rapid mold change and maintenance.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model provides a technical solution: a space-saving mold structure with a combined slider mechanism, which is composed of an upper mold 1, a lower mold 2 and two combined slider mechanisms 3, wherein the two combined slider mechanisms 3 are symmetrically arranged between the upper mold 1 and the lower mold 2, and the two combined slider mechanisms 3 can be moved closer or farther away during the process of closing or opening the upper mold 1 and the lower mold 2;

[0025] The specific structures of the upper die 1, the lower die 2 and the combined slider mechanism 3 are described below:

[0026] First, the upper die 1 includes an upper die base 11, the bottom end of the upper die base 11 is connected to an upper die core 12, the bottom end of the upper die core 12 is symmetrically connected to a plurality of inclined guide columns 13, and positioning holes 14 are provided through the corners of the upper die core 12;

[0027] Secondly, the lower die 2 includes a lower die base 21, the top of the lower die base 21 is connected to a lower die core 22, the top of the lower die core 22 is symmetrically provided with a guide hole 23 and a first-step slide rail 24, the first-step slide rail 24 is located between the guide holes 23, and the corners of the top of the lower die core 22 are connected with positioning columns 25;

[0028] Furthermore, the combined slider mechanism 3 includes a first-order slider 31 which is symmetrically and movably arranged between the upper mold 1 and the lower mold 2. A second guide hole 33 is reserved inside the first-order slider 31, and a plurality of force-guiding blocks 34 are connected to the adjacent ends of the first-order slider 31. A dovetail groove 35 is arranged between every two force-guiding blocks 34. The end of the force-guiding block 34 facing away from the first-order slider 31 is slidably connected to a second-order slider 37, and the sliding trajectory of the second-order slider 37 inside the dovetail groove 35 is in a diagonal shape.

[0029] During the above-described process, it should be noted that the bottom end of the guide post 13 is sequentially inserted into the second guide hole 33 and the first guide hole 23 and can slide relatively. The bottom end of the first-order slider 31 is provided with a first-order track groove 32, and the first-order track groove 32 is engaged with the outside of the first-order slide rail 24 and can slide relatively. When the upper mold 1 and the lower mold 2 are in the mold-closing state, the positioning post 25 is inserted into the positioning hole 14. The end of the force guide block 34 away from the first-order slider 31 is connected with a second-order slide rail 36. The side of the second-order slider 37 is provided with a second-order track groove 38, and the second-order track groove 38 is engaged with the outside of the second-order slide rail 36 and can slide relatively.

[0030] The processes of mold closing and mold opening of this mold structure are as follows:

[0031] During mold closing: The upper mold 1 gradually approaches the lower mold 2. During the approaching process, the guide post 13 will be sequentially inserted into the second guide hole 33 and the first guide hole 23. During the insertion into the second guide hole 33, because the guide post 13 is inclined outward, it will push the first-order slider 31 along the first-order slide rail 24 and move inward by means of the second guide hole 33. The first-order slider 31 will drive a plurality of force guide blocks 34 to move inward synchronously. Also, because the second-order slide rail 36 is inclined, when the force guide blocks 34 move inward, through the second-order track groove 38 and the second-order slide rail 36, the two second-order sliders 37 located inside the dovetail groove 35 will approach. After the distance between the two second-order sliders 37 is reduced, together with the lower mold core 22, they form a product molding cavity, and then injection molding is carried out;

[0032] During mold opening: The upper mold 1 gradually moves away from the lower mold 2. During the moving-away process, when the guide post 13 disengages from the second guide hole 33, because the guide post 13 is inclined outward, it will push the first-order slider 31 along the first-order slide rail 24 and move outward by means of the second guide hole 33. The first-order slider 31 will drive a plurality of force guide blocks 34 to move outward synchronously. Also, because the second-order slide rail 36 is inclined, when the force guide blocks 34 move outward, through the second-order track groove 38 and the second-order slide rail 36, the two second-order sliders 37 located inside the dovetail groove 35 will move away, and the distance between the two second-order sliders 37 increases, releasing the constraint on the product after injection molding, and that's it.

[0033] In summary, the first-order slider 21 drives the second-order slider 37 to act through the force guide block 34, and uses the inclined dovetail groove 35 to change the movement direction to the vertical direction, so that the second-order slider 37 can be made smaller and occupies less space, achieving the purpose of saving space.
