Problems solved by technology
[0003] The currently used injection molds are all condensed through the external condensation pipe during hot injection molding, that is, the condensation pipe is evenly laid on the outside of the mold, which leads to the poor position of the condensation pipe and the cavity. The condensation effect can only be determined according to the position, that is, the condensation effect is poor at the position with large thickness, and the condensation effect is good at the position with small thickness, and the condensation pipe set in this way generally only has one-way flow capacity, which is not suitable for hot injection molding. Condensation molding of the mold is not good

The invention discloses a plastic injection mold with high production efficiency. The plastic injection mold with high production efficiency comprises a movable mold plate, a fixed mold plate and a jet pipe; a cavity is formed in a shaping plate; a condensation pipe is further arranged in the shaping plate; the condensation pipe is located on the side face of the cavity; the condensation pipe andthe side face of the cavity are laid at equal intervals; a hole is formed in one side of the condensation pipe; a driving rod is arranged in the hole in an attached and sliding mode; the executing endof the driving rod stretches into the condensation pipe; and the driving end of the driving rod is connected to an executing mechanism used for driving the driving rod to do reciprocating linear motion. Through equidistant laying of the condensation pipe and the side face of the cavity and the twitching effect of the driving rod in the condensation pipe, the condensation effect of condensate water in the condensation pipe can be improved under the premise of guaranteeing that the condensation of plastic in the cavity is uniform, that is, the relative volume in the condensation pipe is changedthrough reciprocating motion of the driving rod, then the flowing direction of the condensate water is changed, the exchange frequency of heat is increased, the condensation effect is improved, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of plastic molding, in particular to a plastic injection mold with high production efficiency. Background technique [0002] Injection molding is a method for the production of industrial products. Products usually use rubber injection molding and plastic injection molding; injection molding can also be divided into injection molding molding method and die-casting method. [0003] The currently used injection molds are all condensed through the external condensation pipe during hot injection molding, that is, the condensation pipe is evenly laid on the outside of the mold, which leads to the poor position of the condensation pipe and the cavity. The condensation effect can only be determined according to the position, that is, the condensation effect is poor at the position with large thickness, and the condensation effect is good at the position with small thickness, and the condensation pipe set in this way generall...
