2results about How to "Reduce sticking phenomenon" patented technology

The utility model belongs to the technical field of injection molds, and particularly relates to a pre-pumping mechanism for preventing vacuum adsorption mold sticking, which comprises a fixed mold seat plate, the lower side of the fixed mold seat plate is vertically connected with a fixed mold plate in a sliding manner, an elastic reset piece is arranged between the fixed mold seat plate and the fixed mold plate, and a fixed mold insert is arranged in the fixed mold plate; a mold cavity is formed in the fixed mold insert, a sprue bush and a plastic part which are located on the upper side of the fixed mold insert are fixedly connected to the fixed mold seat plate, a screw mounting groove is formed in the fixed mold seat plate, an equal-height screw vertically slides in the screw mounting groove, the lower end of the equal-height screw is fixedly connected with the fixed mold plate, and the elastic reset part is a return spring. A spring mounting groove is formed in the upper side of the fixed mold plate, and the return spring is mounted in the spring mounting groove. According to the utility model, the top of the plastic part can be communicated with the outside, the mold sticking phenomenon of the plastic part caused by vacuum adsorption is reduced, the mold sticking risk of the plastic part is reduced, and the product percent of pass is greatly improved.

This invention relates to the field of pet material technology, and more particularly to a multi-layered coated olive pit cat litter granule, comprising a core layer, a middle layer, and an outer layer. The core layer contains olive pit particles with a particle size of 1.5–3.0 mm. The middle layer coats the outer surface of the core layer and contains guar gum, sodium carboxymethyl cellulose, and zeolite powder. The outer layer coats the outer surface of the middle layer and contains ZAG complex, sodium bicarbonate, vegetable oil, and surfactant. The multi-layered coated olive pit cat litter granule provided by this invention achieves significant improvements in comprehensive performance across multiple dimensions, including water absorption, breakage resistance, deodorization, and antibacterial properties.
