Background

Blow molding is a common method for manufacturing hollow articles, and is another method which is most commonly used in plastic article processing methods besides extrusion, injection molding and mold pressing, and the development is rapid, and the method belongs to the secondary molding technical field. The method comprises the steps of firstly obtaining a semi-molten tubular parison by extrusion or injection molding of thermoplastic resin, then placing the parison in molds of various shapes while the parison is hot or heated to a softened state, immediately introducing compressed air into the parison after the molds are closed, and blowing the closed parison in a rubber-like state in a mold cavity by means of gas pressure so as to enable the parison to cling to the inner wall of the mold cavity to form a hollow product. The parison making and the inflation can be performed separately and independently.

The conventional blow molding equipment for the stacking barrel comprises an extruding unit and a blow molding unit; the extruding unit is used for extruding the tubular blank; the blow molding unit mainly comprises a stacking barrel opening and closing die and a blowing mechanism, and the operation flow of the stacking barrel opening and closing die generally comprises material receiving, molding and demolding. Traditionally, in order to improve the production efficiency of the stacking barrels, one extruding unit can be correspondingly provided with two stacking barrel opening and closing dies, and the two stacking barrel opening and closing dies alternately operate. In actual production, the extrusion unit can extrude a cylindrical material blank only in the process of opening and closing the die and receiving the material by the stacking barrel, and once the opening and closing die of the stacking barrel is moved away from the lower part of the discharge hole of the extrusion unit, the extrusion unit can stop extruding the material and is in a standby state; although the arrangement of the two stacking barrel opening and closing dies can enable the extrusion unit to have shorter standby time to some extent, the standby time is still longer, so that the working efficiency of the stacking barrel blow molding equipment is improved.
