The invention relates to the technical field of plastic forming processing, in particular to a bottle plastic accessory forming machine. The machine comprises a box body and further comprises a mold body structure and a water circulation structure. The mold body structure comprises an upper mold body and a lower mold body, the lower mold body is fixedly connected with the box body and the upper mold body is connected with the lower mold body in a sliding manner. The water circulation structure is used for conveying heat and regulating and controlling the volume of a water bag, the water circulation structure is installed in the box body and comprises a reversing valve structure, the reversing valve structure is fixedly connected with a first water pumping mechanism and a water return pipe, the first water pumping mechanism is connected with the water bag through a first through pipe, and the water bag is fixedly connected with a second through pipe; and the first through pipe and the second through pipe are provided with hose sections, a control valve is installed on the second through pipe, and one end of the second through pipe is connected with a pipe connecting piece communicated with a water return pipe. Under the action of compressed water, self-adaptive adjustment of mold locking force is carried out, and the upper mold body and the lower mold body are locked under the condition of protecting the integrity of the mold body structure.
Description
technical field [0001] The invention relates to the technical field of plastic molding processing, in particular to a molding machine for plastic accessories of bottles. Background technique [0002] Most of the existing plastic accessories are produced by injecting molten plastic into the mold through the injection molding machine, that is, the thermoplastic plastic is made into accessories of various shapes by means of the mold, and the bottle body carrying high-pressure gas needs to be installed at the valve body and the handle. Plastic accessories, which are used to protect the gas cylinder and improve the durability of the gas cylinder. [0003] In the existing injection molding production, in order to increase the quality of the final produced plastic parts, it is necessary to carry out pressure-holding treatment on the plastic parts in the mold, and in the process of pressure-holding treatment, due to the existence of mold expansion force, the formed finished product ...
