Technical Field

The invention discloses a water cooling structure for an insert pin of an automobile plastic die, and belongs to the technical field of dies.

Background

The insert pin of the plastic mould is inconvenient to be provided with a transverse flow channel close to liquid plastic for cooling due to the limitation of the structure and the size, a deep hole groove is generally formed in the insert pin body at present, and cold water is input into the deep hole groove by using external equipment for cooling.

The car plastic mold who uses now inlays needle water-cooling structure and has certain defect, lacks the drainage function, has moisture to stay in the deep hole inslot after rivers accomplish the cooling, causes the inside corrosion of inlay needle body easily for a long time, reduces the life who inlays the needle body, so needs a car plastic mold to inlay needle water-cooling structure and solve above-mentioned problem.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the water cooling structure for the insert pin of the automobile plastic mold, which is used for solving the problems in the background art and has the advantages of convenience in use, convenience in drainage and good cooling effect.

In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides a car plastic mold inlays needle water-cooling structure, includes and inlays needle body, deep hole groove, support column, pipe, outlet pipe and drainage mechanism, deep hole groove is seted up at and is inlayed needle body upper end, the support column is fixed at deep hole inslot portion upside, the pipe passes through the support column and installs in deep hole inslot portion, the outlet pipe is installed at inlays needle body annular side upside, drainage mechanism installs at inlays needle body annular side downside, drainage mechanism includes rubber buffer, arc, stay cord and gim peg, inlay needle body annular side downside and set up the outlet and the outlet left end leads to with deep hole groove mutually, the rubber buffer is installed inside the outlet, the rubber buffer right-hand member is fixed at the arc left end, the arc left end is laminated with inlaying needle body annular side mutually, the stay cord left end is fixed on the arc, the gim peg is installed on inlaying needle body annular side, the rear end of the pull rope is fixed on the annular side face of the fixing bolt.

Furthermore, stay cord and gim peg all are equipped with two sets ofly, and are two sets of stay cord symmetry is installed both ends around the arc, and is two sets of gim peg symmetry is installed in inlaying both sides around the needle body annular side, and is two sets of stay cord left end is all installed couple and is installed on gim peg annular side.

Further, a threaded hole is machined in the upper end of the support column, an external thread is machined on the annular side face of the guide pipe, the guide pipe is installed in the threaded hole, and a sealing ring is installed at the upper end of the support column.

Furthermore, a water delivery pipe is arranged at the upper end of the guide pipe and is connected with external water delivery equipment.

The invention has the beneficial effects that: according to the water-cooling structure for the insert pin of the automobile plastic die, the water outlet, the rubber plug, the arc plate, the pull rope and the fixing bolt are added, so that the water in the deep hole groove can be conveniently discharged, the service life of the insert pin body is prolonged, and the problems that the existing water-cooling structure for the insert pin of the automobile plastic die is lack of a water discharging function, water is remained in the deep hole groove after water flow is cooled, the interior of the insert pin body is easily rusted for a long time, and the service life of the insert pin body is shortened are solved.

The design is convenient for replacing the guide pipe due to the addition of the threaded hole and the external thread, improves the sealing property between the support column and the guide pipe due to the addition of the sealing ring, and is convenient for conveying cold water to the interior of the deep hole groove due to the addition of the water conveying pipe and the external water conveying equipment.
