Single sub-surface injection mold services
Single sub-surface plastic injection mold is a mold by institutions, single-parting from the injection mold cavity, molding parts, casting systems, oriented institutions, the top of the device, temperature control system and structure of the component parts.
(1) cavity
Mold cavity for molding plastic parts part, because the cavity is directly molded plastic parts, hence the shape of the cavity should be the same rotten shape of plastic parts, generally by the cavity mold cavity, core components.
(2) forming parts
Constitute parts plastic mold cavity referred to as forming parts, typically including core (internal-shaped molding plastic parts
Like), cavity (the external shape of the molding plastic parts).
(3) pouring system
Plastic injection machine nozzle from the cavity of the lead runner is called gating system, casting sprue system points, runner, gate, four parts of cold material points, is set by the gate, pull the lever and set the template material flow channel component.
(4)-oriented institutions
To ensure the dynamic model with fixed mold clamping designed when precise orientation of the parts. Usually oriented columns, pilot hole or die in the dynamic model be consistent with each other were set on the inside and outside the cone formed.
(5) introduction of equipment
In the mold process, the plastic parts from the mold in the launch of the device. Some of the injection mold device to avoid the introduction of the process launched at the top of the board skew, also has a guide part, the push plate to maintain horizontal movement. By the fader, push plates, putting fixed plate, reset lever, pull the sprue material rod, bearing nails, push plate and push plate guide pin guide sleeve component.
(6) temperature control and exhaust systems
Injection process in order to meet the requirements of the mold temperature, mold with cooling or heating systems, cooling systems are generally set up in the mold cooling water, cooling system is formed by the cooling water and faucets. Heating is installed in or around the mold heating elements, such as electric heating elements. In the injection molding process, in order to exclude the gas cavity model, and often need to open the exhaust system.
(7) structural parts
Used for mounting or supporting parts forming the various parts of the aforementioned institutions and parts. Bearing parts assembled together, can constitute the basic skeleton of injection molds.
