Description

Technical Field

[0001] The utility model relates to the technical field of raw material screening of injection molding machines, and specifically relates to a raw material screening device for injection molding machines. Background Technique

[0002] An injection molding machine is also known as an injection molding machine or an injection machine. It is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies, and is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] For example, a raw material screening mechanism of an injection molding machine with the publication number CN220409471U solves the problem that in the prior art, affected by the characteristics of injection molding raw materials, some injection molding raw materials will have a certain viscosity, resulting in the situation that during the screening process, a small part of the raw materials may adhere to the inside of the screening mechanism, thereby affecting the subsequent screening operation efficiency. A raw material screening mechanism of an injection molding machine includes a housing. One side of the top of the housing is fixedly connected with a feed hopper. Two screening frames are fixedly connected inside the housing along the vertical direction of the housing. Both sides of the outer wall of one side of the housing are fixedly connected with storage housings. The utility model enables the personnel to perform rapid screening operations on the raw materials remaining on the surface of the screening frame after each use of the screening device, thereby avoiding the situation of blockage of the screening frame caused by the residue of the raw materials, strengthening the practicability of the screening mechanism, and reducing the number of subsequent maintenance times for the personnel.

[0004] However, according to the working principle proposed in the above patent, the applicant believes that although the above device can enhance the practicability to a certain extent, in actual use, the melting efficiency of the subsequent process may be affected due to the different sizes of the injection molding machine raw materials, and there may be metal materials in some raw materials, further affecting the melting efficiency.

[0005] Therefore, in view of the above problems, a raw material screening device for injection molding machines is proposed. Content of the Utility Model

[0013] Preferably, a control panel is fixedly installed outside the vibration motor, and operation buttons are arranged on the surface of the control panel.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. Through the cooperative setting of multiple sieve frames, the utility model can classify the raw materials of the injection molding machine with different volumes and sizes. The mesh of the upper sieve frame is relatively large, which can screen and retain the raw materials with larger volumes in the upper sieve frame. The sieve plate inside the magnetic sieve frame uses magnetic materials, which can adsorb some metal materials that may exist in the raw materials, so as to separate them from the raw materials. Moreover, the mesh of the magnetic sieve frame is finer than that of the upper sieve frame, and the mesh of the lower sieve frame will be further reduced. The three-layer sieve frame can screen the raw materials multiple times, so as to better form multi-level screening of the raw materials according to the different volumes and sizes.
