Description

Technical Field

[0001] This utility model belongs to the field of injection molding material supply technology, and relates to a centralized material supply device for preventing blockage during tail box injection molding. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Existing injection molding machines typically employ automatic feeding, and the feeding process also includes a mixing function.

[0003] For example, patent number CN202221053217.5 discloses a feeding device for an injection molding machine, including a feeding shell disposed on the upper side of a spiral extrusion cylinder; a feeding port is provided on the feeding shell; a feeding chamber is provided inside the feeding shell; a transmission rod is provided inside the feeding chamber; an extrusion mechanism and a stirring mechanism are provided on the transmission rod; a discharge port is provided at the bottom of the feeding chamber; a heating component is provided inside the discharge port; a feeding port is provided at the top of the spiral extrusion cylinder opposite to the discharge port; a gate is provided inside the feeding port. When the raw material enters the feeding shell, the drive motor is started, and the drive motor drives the transmission rod to rotate; due to the circumferential limitation of the extrusion block, it can only move horizontally, thereby extruding the raw material and causing it to be extruded outward from the lower discharge port, and being heated during the process of passing through the discharge port.

[0004] The disadvantage of the aforementioned feeding device is that its bottom outlet is prone to blockage. To address this, we have designed a centralized feeding device for preventing blockage during tail box injection molding. Summary of the Invention

[0005] The purpose of this invention is to provide a centralized material supply device for preventing blockage during tail box injection molding, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: a centralized feeding device for preventing clogging during tail box injection molding, comprising an injection molding machine mounting plate, a feeding hopper, and a feeding pipe. The feeding hopper is installed at the center of the top of the injection molding machine mounting plate. One end of the feeding pipe is connected to the feeding port of the feeding hopper. The device also includes a circular air disc located inside the feeding hopper. A central stirring shaft is located at the center of the bottom of the circular air disc. A cross-shaped stirring part is fitted onto the outer surface of the central stirring shaft. A telescopic air rod is installed at the bottom of the circular air disc and connected to the cross-shaped stirring part. A detachable inflation connection is installed on the air inlet of the circular air disc.

[0007] In the aforementioned tail box injection molding anti-clogging centralized feeding device, a top plate is bolted to the center of the top of the feeding box. A servo motor is mounted on the top of the top plate, and a key shaft connecting plate is mounted on the output shaft of the servo motor. A key shaft connecting part is mounted at the center of the top of the circular air disc, and the key shaft connecting part is keyed to the key shaft connecting plate. The purpose of this arrangement is to utilize the power output of the servo motor, and then use the key shaft connecting plate to transmit the power to the key shaft connecting part, driving the circular air disc to rotate and achieve the mixing operation.

[0008] In the aforementioned tail box injection molding anti-clogging centralized feeding device, a centralized feeding section is installed at the bottom of the injection molding machine mounting plate. The top of the centralized feeding section has a main flow channel connecting to the material inlet of the feeding hopper, and the bottom of the centralized feeding section has two auxiliary flow channels. This design allows for centralized feeding to the two auxiliary flow channels, facilitating synchronous injection operations.

[0009] In order to reduce the impurities in the molten material, disc filter covers are installed at the bottom of the two auxiliary flow channels, and the bottom of the disc filter covers is provided with an inner filter screen.

[0010] In the aforementioned centralized material supply device for preventing blockage during tail box injection molding, bolt connecting discs are installed at both symmetrical corners of the injection molding machine mounting plate. This arrangement aims to achieve a better installation effect, making the connection between the injection molding machine mounting plate and the injection molding machine platform more secure.

[0011] In the aforementioned tail box injection molding anti-clogging centralized feeding device, a heating element is installed at the bottom of one side of the feeding box, and the heating wire of the heating element is arranged along the inner side wall of the feeding box. The purpose of this arrangement is to achieve a good heating effect, facilitate the heating of the material, and ensure good flowability of the material.

[0012] Compared with the prior art, the advantages of this utility model tail box injection molding anti-clogging centralized feeding device are as follows: by installing a telescopic air rod at the bottom of the circular air plate, the telescopic air rod is connected to the cross-shaped stirring part, and the air inlet of the circular air plate is equipped with a detachable inflation connection part. In this way, when it is necessary to clear the blockage, gas can enter the telescopic air rod, and the telescopic air rod extends so that the cross-shaped stirring part moves down to the discharge port of the feeding box to realize the blockage clearing operation and effectively prevent blockage.
