Molding device for high-precision plastic carrier tape product

Abstract

The invention discloses a molding device for a high-precision plastic carrier tape product. A feeding mechanism, an actuating mechanism and a constant-speed drawing mechanism are arranged sequentially between a raw material tray and a material collecting tray, wherein heating blocks are arranged between the feeding mechanism and the actuating mechanism; one end of the actuating mechanism is fixed on a worktable, and the lower part of the other end of the actuating mechanism is connected with a mold; the actuating mechanism comprises a support upright column, a rocker link, a mold hoisting device and a travel adjusting device; the mold comprises an upper mold assembly and a lower mold assembly; the upper mold assembly comprises a face plate, an upper mold seat and an upper mold unloading plate; the lower mold assembly comprises a cavity plate, a lower mold unloading block and a lower mold unloading block fixing plate; an unloading fixing plate ejection pin is arranged on the lower mold unloading block fixing plate; and an unloading plate jacking spring is arranged at the lower part of the lower mold unloading block fixing plate and fixed on an equipment bottom plate at the lower part of the worktable. The molding device for the high-precision plastic carrier tape product is simple in structure, easy to operate and stable in quality, raw materials are uniformly heated and is good in molding consistency, so that stretching sinking of edge lines is avoided.

Description

technical field [0001] The invention relates to the technical field of carrier tape products, in particular to a molding device for high-precision plastic carrier tape products with simple structure, convenient operation, stable operation, uniform heating of raw materials, good molding consistency, and no sideline stretching and collapse. Background technique [0002] Carrier Tape refers to a strip-shaped product used in the field of electronic packaging. It has a specific thickness and has holes (also known as pockets) equidistantly distributed in its length direction for holding electronic components. and pilot holes for indexing. Carrier tapes are mainly divided into plastic carrier tapes and paper carrier tapes according to their materials. At present, plastic carrier tapes are widely used. Plastic carrier tape products were usually used as packaging carriers for electronic components such as crystal oscillators, inductors, capacitors, etc. in the early days. The overal...

Problems solved by technology

Although the above method has produced a plastic carrier tape for microchips, there are certain shortcomings: it cannot meet the higher demand standards for microchip packaging during use, for example: the bottom is not formed properly (rounded corners), because Various serious problems such as inconsistent stamping and warping of the mold caused by uneven heating
