detailed description

The following will be described in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present utility model.

As shown in Figures 1-3, a button pen driving core mold structure of the present invention includes a female mold fixing plate 1, a female mold plate 2, a male mold plate 3, a male mold bearing plate 4, a mold foot 6 and a male mold plate connected in sequence. Die fixing plate 7, described male mold fixing plate 7 is provided with panel guide post 12, and panel guide post 12 runs through thimble panel 10 and thimble base plate 11, and thimble panel 10 is installed limit stop column 5 and thimble 9, and thimble The linear motion of 9 depends on the movement of the thimble panel 10 and the thimble bottom plate 11, and the panel guide post 12 cooperates with the panel guide sleeve arranged on the thimble panel 10 and the thimble bottom plate 11, so as to realize the linear movement accuracy requirement of the thimble 9, limit The stop post 5 is to limit the moving distance of the thimble 9 on the basis of ensuring the smooth demoulding of the product, so as to avoid the excessive length of the head of the thimble 9 during the mold clamping process, causing the thimble 9 to be deformed under pressure; the male template 3 is provided with Male mold 17, male mold 17 is connected with branch flow channel 13, and branch flow channel 13 is connected with main flow channel 14, and main flow channel 14 and branch flow channel 13 are arranged in I shape, guarantees that the injection pressure of each cavity is equal, increases injection molding simultaneously The number of products, the branch flow channel 13 is also connected to the exhaust groove 15, and the exhaust groove 15 is also connected to the male mold 17.
