Problems solved by technology
[0002]The production of the existing rear large connecting rod generally adopts a two-step processing method. First, the rough workpiece is rough-machined by injection molding, and then drilling, turning and milling are carried out. The fine processing in the aspect finally forms the final formed rear dragging large connecting rod workpiece. The operation is more troublesome, and in order to facilitate the mold taking, an ejection mechanism that can be operated externally must be installed in the lower mold, which makes the mold structure complicated and increases the cost. The cost of the mold is higher, so the efficiency is lower and the cost is higher

The invention discloses an injection mould for a large rear-towing connecting rod. The injection mould comprises an upper mould and a lower mould, wherein a horizontal hole channel and a vertical hole channel which are intercommunicated are formed on the lower mould; a mould picking block and a mould core which are interconnected are arranged in the horizontal hole channel and the vertical hole channel; a mould core hole is formed in the top part of the mould core; a cavity body is formed on the back surface of the upper mould; a connector forming cavity and a pouring channel which can be folded to each other are oppositely formed on the back surface of the upper mould and the front surface of the lower mould; the mould core hole, the vertical hole channel wall, the cavity body and the connector forming cavity form a mould cavity which can form the large rear-towing connecting rod; a positioning hole channel which passes through the front surface of the upper mould and the cavity body is arranged; and a bolt which passes through the positioning hole channel and then is inserted into the mould core is arranged; and the bolt can form a through hole for the large rear-towing connecting rod during the injection mould. By adopting the injection mould for the large rear-towing connecting rod, a component can be formed by once injection molding; and the injection mould is low in cost and high in efficiency.
Description
technical field [0001] The invention relates to an injection mold for trailing a large connecting rod. Background technique [0002] The production of the existing rear-drag connecting rod generally adopts a two-step processing method. First, the rough workpiece is rough-machined by injection molding, and then the fine machining of drilling, turning and milling is carried out, and finally the final-shaped rear-drag Dalian is formed. Rod workpieces are cumbersome to operate, and in order to facilitate mold taking, an ejection mechanism that can be operated externally must be installed in the lower mold, which makes the mold structure more complex and increases the cost of the mold, which is less efficient and more costly. Contents of the invention [0003] The purpose of the present invention is to provide an injection mold for trailing large connecting rods which is easy to operate, can be molded at one time, has high efficiency and low cost. [0004] In order to achieve ...
