Injection molding machine for flat needle material strap

Abstract

The invention relates to an injection molding machine for a flat needle material strap. The injection molding machine comprises a machine frame, an injection molding mechanism and an injection mold located on the injection molding procedure. The injection mold comprises an upper mold body and a lower mold body. The upper mold body comprises an upper mold base plate, a stripper plate, an upper mold core board and an upper mold core which are correspondingly matched. The lower mold body comprises an ejection mechanism, a lower mold core board and a lower mold core. The lower mold core is installed on the lower mold core board, and the upper mold core and the lower mold core are correspondingly matched. The lower mold core is provided with a plurality of pouring cavities. The lower mold core is provided with a material strap guide base which is correspondingly matched with the pouring cavity. The material strap guide base is provided with a material strap guide groove with the two ends being through. A material strap feeding device is arranged at the material strap led-in end opening side of the material strap guide groove, and a material strap intermittent traction device which is adapted to the injection molding procedure and used for intermittent traction of the flat needle material strap is arranged at the material strap led-out end opening side of the material strap guide groove. The injection molding machine can automatically convey the flat needle material strap and has the advantages of being high in degree of automation and high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, specifically a flat needle strip injection molding machine. Background technique [0002] Such as figure 1 As shown, the flat needle strip 9 includes a plurality of units. The flat needle strip includes two side plates 91 and flat needles 92 connecting the two side plates 91. The side plates 91 are provided with positioning holes 191. The flat needle strip 9 Plastic block 93 needs to be injection molded on the flat pin 92. Injecting plastic blocks on the flat needles is completed by an injection molding machine. The existing flat needle strip injection molding machine is a semi-automatic equipment. Its main structure includes a frame, an injection mechanism installed on the frame, and an injection mold. The upper mold and the lower mold, the upper mold includes the upper mold base plate, the stripper plate, the upper mold core installation plate and the upper mold core embed...

AI Technical Summary

Problems solved by technology

The flat needle material belt adopts short material belt (the flat needle material belt has only a few flat needle units), which leads to the manual operation of placing and taking the product on the mold of the injection molding machine, and it is impossible to realize the material belt directly passing through the mold for flat needle material With automatic distribution, which reduces production efficiency and increases enterprise costs
