TH3314C3 - Plastic Telephone Rail Mold Set - Google Patents

Abstract

The invention involved a set of plastic telephone trunking molds. With development Improved to have two exit channels of telephone rails resulting in higher production capacity. It can reduce the screw back pressure due to the resistance behind the hot mold, thus saving energy and reducing the cost of machine maintenance such as drive gears and bearings (barring) can be easily removed for cleaning. The die set consists of a hot die and a cooling die or vacuum sizer, where the hot die is characterized by having two outlet holes for the phone holder, and then forward to the cold mold. Number of two that can adjust the distance between them. The interior has a cross-section in the shape of a telephone cable. There is also a cooling system and a vacuum system for cooling from telephone rails.

Claims (3)

1. Plastic phone holder mold set consists of a hot die (1) where the hot die (1) consists of The rear hot mold (9) has a cavity inside for receiving the molten material from the extruder (3). One cavity is connected to the front hot die (10) where the inside has a cavity with a cross-section to form a cable rail phone For the outlet of the telephone trough (4), the exterior of the hot mold (1) was installed with at least 2 heaters (5) to heat the material. Inside the hot mold (1), the phone rack that is rolled out from the hot mold (1) is sent to the cold mold (2) not the cooling die or vacuum sizer (2) away from The mold is heated (1) in the same plane. The inside of the cold mold (2) consists of a cavity with a cross-section in the form of a trough parallel to the length of the cold mold Additionally, the exterior of the mold (2) contains at least one water inlet hole (6) and at least one water outlet (7) hole to cool the phone hose rail and also includes a suction hole. Air (8) is exited at least one hole from the cold mold to drain the heat from the phone rail and help shape the workpiece to be beautiful as desired. Such plastic telephone holder mold set Its characteristic is that the hot mold (1) has two outlets for telephone rails, where There are two C-shaped cross-sectional areas (C) of the cold mold (2) that can be adjusted between each other to suit the spacing of the telephone trough being rolled out of the hot die (1 ) 2.Plastic Telephone Rail Mold Set According to claim 1, where the front hot mold (10) and the rear hot mold (9) can be taken apart. 3.Plastic Telephone Rail Mold Set According to claim 1, where the cold mold (2) is a metal platform with a length of 15-50 centimeters.
