Description

An easily disassembled two-color injection molding machine

technical field

The utility model relates to an injection molding machine, in particular to an easily disassembled two-color injection molding machine.

Background technique

Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms: plunger type, screw type, and screw pre-molded plunger injection type. The most widely used is the screw type. Its function is that in a cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized within a specified time, and then the molten plastic can be injected into the mold cavity through the screw under a certain pressure and speed.

At present, there are many injection molding machines in the prior art, such as the Chinese utility model patent "An Improved Two-color Injection Molding Machine with Preheatable Mold" with the application number CN201420298735.2, which includes a motorized injection molding template and a fixed template of the injection molding machine. A two-color injection molding machine turntable is arranged on the two-color injection molding machine, and a primary male mold and a secondary male mold with symmetrical positions are fixed on the two-color injection molding machine rotary table. A primary female mold and a secondary female mold corresponding to the position of the male mold, an infrared radiator and a controller for controlling the opening and closing of the infrared radiator are arranged in the primary female mold. However, due to the vertical design of the injection molding machine in this solution, it needs to be manually lifted for cleaning and maintenance, which is time-consuming and laborious, and only one end can discharge the material, so the material rate is low.

Utility model content

In order to solve the above problems, the utility model is realized through the following technical solutions:

An easy-to-disassemble two-color injection molding machine, including a box body. The middle part of the box body is a feeding chamber, and the two sides are pushing chambers. The lower part of the feeding chamber is equipped with a heating furnace. The box body is an arched tubular structure. The feeding chamber is an inclined cylindrical pipe with an open end and communicates with the inside of the feeding chamber. A rolling and stirring structure is arranged in the feeding chamber, and a screw is arranged in the pushing chamber. The screw is driven by a motor and the motor is connected with the pushing chamber. Ends are detachable.

The rolling and mixing structure includes an upper roller set and a lower mixer.

The threaded end surface of the screw rod is provided with an axially penetrating through hole.

Two feeding funnels are arranged side by side on the top of the feeding chamber, and the two feeding funnels are located above the rolling and stirring structure.

The roller set includes two rollers arranged side by side and running opposite to each other.

A nozzle for injecting molten material into the mold cavity is provided under the end of the pushing cavity.

Beneficial effect:

The utility model provides an easy-to-disassemble two-color injection molding machine, which has the following advantages: 1) Compared with the traditional injection molding machine, when disassembling the screw rod, it needs to be lifted from the bottom up, and the weight is heavy, and the labor efficiency is low. It is improved to use the self-weight drop disassembly of the screw, which is very convenient for cleaning and maintenance; 2) The arched structure is adopted to prevent the accumulation of materials in the middle, and the materials enter from the highest position in the middle, and are rolled and stirred and heated by the heating furnace in the lower part. This link is as follows: Preheating, compared with the traditional screw injection molding machine, makes the material soften earlier; 3) The screw thread in the pushing chamber is provided with a through hole, which is designed to achieve maximum contact with the molten material during the process of rotating the pushing material 4) The inclined material pushing chamber can allow the molten material to flow down due to its own weight, reducing the energy consumption of the motor. To sum up, the utility model improves the structure of the existing injection molding machine to make it easier to load and unload during maintenance and cleaning, and the unique structure of the box body greatly improves the efficiency and practicability of injection molding.
