Description

Injection molding raw material drying device

Technical Field

The utility model relates to an injection molding machine technical field, a raw materials drying device moulds plastics specifically says so.

Background

An injection molding machine is also known as an injection molding machine or an injection machine. It is a main forming equipment for making various shaped plastic products from thermoplastic plastics or thermosetting plastics by using plastic forming mould. The device is divided into a vertical type, a horizontal type and a full-electric type. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

The injection molding machine mainly comprises an injection system, a mold closing system, a hydraulic system and an electric control system.

The role of the injection system: the injection system is one of the most important components of an injection molding machine, and generally has 3 main forms of plunger type, screw type and screw pre-molding plunger injection type. The most widely used is the screw type. The function of the injection molding machine is that after a certain amount of plastic is heated and plasticized in a specified time in one cycle of the injection molding machine, the molten plastic is injected into a mold cavity through a screw at a certain pressure and speed. After injection, the melt injected into the mold cavity remains set. Composition of the injection system: the injection system consists of a plasticizing device and a power transmission device. The screw injection molding machine plasticizing device mainly comprises a feeding device, a charging barrel, a screw, a glue passing assembly and a nozzle part. The power transmission device comprises an injection oil cylinder, an injection seat moving oil cylinder and a screw rod driving device (a glue melting motor).

The action of the mold closing system is as follows: the mold closing system has the function of ensuring that the mold is closed, opened and ejected. Meanwhile, after the mold is closed, enough mold clamping force is supplied to the mold to resist the mold cavity pressure generated when molten plastic enters the mold cavity, and the poor situation of a product caused by the opening of the mold is prevented. The composition of the mold closing system is as follows: the mold closing system mainly comprises a mold closing device, a machine winch, a mold adjusting mechanism, an ejection mechanism, a front fixed template, a rear fixed template, a movable template, a mold closing oil cylinder and a safety protection mechanism.

The hydraulic transmission system is used for realizing that the injection molding machine provides power according to various actions required by the technological process and meeting the requirements of pressure, speed, temperature and the like required by each part of the injection molding machine. The hydraulic injection molding machine mainly comprises respective hydraulic components and hydraulic auxiliary components, wherein an oil pump and a motor are power sources of the injection molding machine. Various valves control the pressure and flow of the oil, thereby meeting various requirements of the injection molding process.

The electric control system is reasonably matched with the hydraulic system, and the technological process requirements (pressure, temperature, speed and time) and various program actions of the injection machine can be realized. The device mainly comprises an electric appliance, an electronic element, an instrument (see the right lower drawing), a heater, a sensor and the like. Generally, there are four control modes, manual, semi-automatic, full-automatic and adjustment.

Except for the injection molding machine, the quality of injection molding raw materials also relates to the quality of injection molding machine products, and at present, when polypropylene and polyethylene raw materials in the market enter the injection molding machine (or a film coating machine), if moisture exists, the phenomena of air bubbles, film breaking and poor forming can occur.

Disclosure of Invention

In order to solve the problem, the utility model aims at providing a raw materials drying device moulds plastics.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a raw materials drying device moulds plastics, includes feed cylinder and feeder hopper, and the feeder hopper passes through the one end intercommunication of tee bend and cartridge heater, and the other end of cartridge heater then gives vent to anger with the fan and holds the intercommunication, and the tee bend other end passes through blast pipe and feed cylinder top inner shed shower nozzle intercommunication down, is provided with the fan that can free rotation under the shower nozzle and chops and mix the blade, is provided with electric heating wire in the cartridge heater, and the upper end of feed cylinder sets up the gas outlet, and the lower extreme then is the feed opening of infundibulate, and the feed.

Further, the heating cylinder is provided with a thermocouple which extends into the heating cylinder, the thermocouple is electrically connected with the controller, and the controller controls the electric heating wire and the fan to rotate.

Furthermore, the fan chopping blade is rotatably fixed at one end of the horizontal support rod in the charging barrel through the rotating shaft at the bottom.

Through the arrangement, the heated materials are sprayed out by the spray head, and the sprayed materials are pushed to rotate quickly by the fan in a chopping mode, so that the materials are scattered, particles are prevented from being generated, and the dehydration effect of the materials is greatly improved.
