Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing.
[0019] like figure 1 , figure 2 , image 3 As shown, the transparent knob injection mold of the present invention includes a movable mold 1 and a fixed mold 2. The center of the movable mold 1 is provided with a stem 3 matching the inner cavity of the transparent knob. A set of transparent knob positioning grooves can be formed and a slider mechanism with a linearly telescopic slider 4 is provided. The slider mechanism is set on the movable mold 1, and the movable mold 1 is provided with a limit corresponding to each set of slider mechanisms. The front positioning device and the rear positioning device of the linear telescopic position of the slider 4, the fixed mold 2 is provided with a driving block 5 that drives the slider 4 corresponding to each group of slider mechanisms, and the movable mold 1 is also provided with three for jacking. The square ejector pin of the ...

The invention discloses a transparent knob injection mould which comprises a movable mould (1) and a fixed mould (2), a core column (3) matched with a transparent knob inner cavity is arranged on the center position of the movable mould (1), four groups of slide block mechanisms which mouldable transparent knob positioning grooves can be formed in and are provided with slide blocks (4) linearly telescopic are arranged on the periphery of the core column (3), the slide block mechanisms are arranged on the movable mould (1), a front positioning device and a rear positioning device correspond to linear telescopic position of the slide block (4) of each slide block mechanism in a limiting mode and are arranged on the movable mould (1), and a driving block (5) which corresponds to the slide block (4) of each slide block mechanism in a driving mode is arranged on the fixed mould (2). The transparent knob injection mould can prevent split joint lines from being left on the top surface and side faces of a transparent knob and can completely meet technical requirements of products.
Description
technical field [0001] The invention relates to the technical field of injection molds, in particular to a transparent knob injection mold. Background technique [0002] At present, there is a transparent knob, which is in the shape of a cover and has four positioning grooves at the bottom of the inner wall. After the transparent knob is molded, there should be no splicing lines on the top and side surfaces, so the conventional diagonal tie rod method cannot be used for injection molding, because in this way, splicing lines must be left on the top and side surfaces of the transparent knob, so that The technical requirements of the product cannot be met. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an injection mold for transparent knobs that avoids splicing lines on the top and side surfaces of the transparent knobs and can fully meet product technical requirements. [0004] The technical solution of the pre...
