Embodiment Construction

[0018] see Figure 1-3 The shown multi-row joist type large leakboard bottom plate molding die includes a corresponding upper mold (punch mold) 2 and a bottom mold (concave mold) 4 for pressing and forming a large leakboard bottom plate, and the two ends of the bottom mold are tightly Equipped with two positioning pins 1, holes corresponding to the positioning pins are provided at both ends of the upper mold. Two pairs of side stoppers 5 are respectively at the two ends near the bottom mold. Every pair of side stoppers is connected on the bottom mold by bolt 7. The inner surfaces of each pair of side stops are respectively in contact with the two side surfaces of the upper mold and the bottom mold. Two supporting plates 6 are fastened in the middle of both sides of the bottom mold by screws 3, and the upper surface of the supporting plate is flush with the upper surface of the bottom mold.

Abstract

The invention provides a molding mould which can guarantee the shape and position precisions of a multi-row joist type platinum alloy bushing baseplate convex groove and a manufacture method thereof. The molding mould mainly comprises an upper mould and a bottom mould for molding the baseplate convex groove, wherein the upper mould and the bottom mould are opposite to each other, both sides of the bottom mould are fixed with a side stop block for guaranteeing the mould closing precision, and both ends of the bottom mould are respectively provided with a positioning pin. The molding method comprises the following steps of: punching a discharge spout mounting hole and positioning holes on a plate, wherein each pair of positioning holes determine the position of a convex groove and are respectively arranged at both ends of the plate in the longitudinal direction, the distances between each pair of positioning holes are all equal, and spaces between every two adjacent pairs of positioning holes are equal; positioning and placing the plate on the bottom mould through the two positioning pins, then closing the mould and placing the molding mould in a press for pressing out the convex grooves; gradually molding to obtain a baseplate with multiple convex grooves; and finally, removing allowance parts with the positioning holes at both ends of the baseplate and shaping to obtain a baseplate conforming to the requirements.

Description

[0001] Field [0002] The invention relates to a molding method and a mold for a multi-row joist-type large bushing plate, which is applied to continuous glass fiber platinum (platinum-rhodium alloy) bushing processing, and belongs to the field of mechanical manufacturing (precious metal) cold processing technology and equipment. Background technique [0003] The bottom plate of the multi-row joist type large leakage board has multiple groups of leakage nozzle installation holes in the transverse direction, and one group of leakage nozzle installation holes has two rows. Convex grooves are formed between each group of leak nozzle installation holes. At present, there are mainly two processing methods, one is to visually determine the pressing position of the convex groove by scribing, and the other is an integral one-time molding method. Scribing and visual inspection cannot ensure that multiple rows of convex grooves are parallel and equidistant to each other, which not only...
