Description

Technical Field

[0001] The utility model relates to the technical field of raw material impurity removal devices, in particular to a raw material impurity removal device for injection molding of automobile air-conditioning panels. Background Art

[0002] The automobile air-conditioning panel is mainly used to seal the air outlet of the automobile air-conditioner, and at the same time guide the air outlet position of the automobile air-conditioner through the air outlet pipe. The automobile air-conditioning panel needs to be injection molded during the processing. The injection molding machine needs to use a de-impurity device to remove impurities from the molten plastic raw materials when loading.

[0003] For example, the announcement number is: CN213500497U (named as a kind of impurity removal device for feeding injection molding machine), which includes an impurity removal barrel with an opening at the top, a discharge pipe is connected to the bottom of the impurity removal barrel, two layers of impurity removal boxes are arranged horizontally inside the impurity removal barrel, the bottom plates of the two layers of impurity removal boxes are both magnet adsorption plates, and a plurality of filtering holes are opened on the bottom plates of the two layers of impurity removal boxes, and a cover body is arranged on the top of the impurity removal barrel. Plastic particles are poured into the impurity removal barrel from the top of the impurity removal barrel, and the plastic particles first pass through the impurity removal box located on the upper layer. Since the bottom plate of the impurity removal box is a magnet adsorption plate, impurities such as iron filings in the plastic particles can be adsorbed, and some larger ones can be removed. The impurities remain in the upper impurity removal box, and then the plastic particles passing through the filter holes pass through the lower impurity removal box. The bottom plate of the impurity removal box adsorbs and filters the impurities such as iron filings in the plastic particles again. After that, the plastic particles passing through the filter holes enter the feed barrel of the injection molding machine from the discharge pipe connected to the bottom of the impurity removal barrel. The iron filings and other impurities in the plastic particles are adsorbed and filtered through the two layers of impurity removal boxes, reducing the possibility of damage to the injection molding machine equipment caused by impurities such as iron filings, thereby improving the injection molding quality of the product; at the same time, during the filtering process, the cover is placed in the impurity removal barrel, which can reduce the impurities in the external environment from entering the impurity removal barrel and affecting the impurity removal effect of the impurity removal barrel.

[0004] The above-mentioned raw material impurity removal device removes impurities from the plastic raw materials through the pull-out perforated plate structure. However, once the sieve holes are blocked during the impurity removal process, the injection will be blocked, resulting in poor feeding efficiency of the injection molding machine. For this reason, we provide a raw material impurity removal device for injection molding of automobile air-conditioning panels. Utility Model Content
