The utility model relates to the technical field of hollow blow molding machines, in particular to a demolding assembly and a novel high-speed multi-layer hollow blow molding machine for chemical industry, comprising: clamping plates and positioning holes, the positioning holes are formed at the top end of a bottom plate, two groups of clamping plates are provided, ejector rods are fixed at the ends of the two groups of clamping plates away from each other, the ejector rods are movably inserted into the surfaces of clamping plate mounting rods, a limit mechanism is arranged between the ejector rods and the clamping plate mounting rods, a side plate is fixed at one end of the clamping plate mounting rods away from the ejector rods, the side plate is fixed at the top end of the bottom plate, and a mold is arranged at the top end of the bottom plate. The beneficial effects are that: after the blow molding of chemical products is completed, part of the residual material is filled in the space formed between the positioning holes at the top end of the bottom plate and the two groups of clamping plates. When the ejector rods of the hydraulic ejector mechanism retract to make the mold away from the products, the two groups of clamping plates and the inner walls of the positioning holes play a positioning role on the products, preventing the products from being adsorbed on the inner walls of the mold cavity and moving along with the mold, thereby achieving an automatic demolding effect.
