Abstract
The invention discloses an internal cooling effect improvement structure of an injection mold. The internal cooling effect improvement structure of the injection mold comprises a movable mold plate, a fixed mold plate, a water returning device, a water distributor and a water returning tank, wherein a male mold is fixed to the movable mold plate; a female mold is fixed to the fixed mold plate; the water distributor is fixed to the movable mold plate and connected with the water returning device; the water returning device is connected with the water returning tank. The water distributor is composed of a main water inlet, a transverse pipe and a vertical pipe, wherein the main water inlet is fixedly connected with one end of the transverse pipe; the other end of the transverse pipe is connected with the vertical pipe in a seamless mode; a plurality of water diversion inlets are evenly distributed in two sides of the transverse pipe; a plurality of first water diversion outlets are evenly distributed in one lateral surface of the vertical pipe and each provided with a first water outlet pipe nozzle; a plurality of second water diversion outlets are evenly distributed in the front end surface of the vertical pipe. The internal cooling effect improvement structure of the injection mold is simple in structure, obviously improves the cooling effect, relieves the workload of workers, relieves labor intensity of mold-replacement workers and largely improves production efficiency.
Description
【Technical field】 [0001] The invention relates to the technical field of mold structures, in particular to a structure for improving the cooling effect inside an injection mold. 【Background technique】 [0002] The injection mold consists of a movable mold and a fixed mold. The movable mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a gating system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product. At present, the injection molding of PVC pipe fittings generally cannot use hot runners, which are all cold runners with large nozzles. When the mold workers change the mold, due to the many, complex and disordered cooling water pipes, not only the overall appearance of the machine is affected, but also the normal opera...
