Embodiment

[0022] refer to Figure 1-2 , a uniformly processed general-purpose blow molding mold, including a base body 1, the base body 1 is divided into two half parts, the two half parts are fixed to each other by a buckle structure, and the inside of the two half parts are common A mold cavity is opened and a mold cover 3 is fixedly connected in the mold cavity. A connecting layer 6 is provided on the upper side of the mold cover 3, and an air injection pipe 2 is inserted in the connection layer 6. The air injection pipe 2 runs through the top wall of the base body 1 and is connected with the It communicates with the external high-pressure air pump. The base body 1 is provided with an annular circulation chamber 5, and the outer side of the cavity is provided with a fixed groove 6. The side of the fixed groove 6 close to the mold casing 2 is provided with multiple sets of heat exchange structures;

[0023] Each set of heat exchange structures includes a piezoelectric sheet 7 symmetri...

Abstract

The invention discloses a universal blow molding mold for uniform machining. The universal blow molding mold comprises a base body, wherein the base body is divided into two half body parts; the two half body parts are fixed to each other through a buckle structure; a cavity is formed in the two half body parts; a mold sleeve is fixedly connected in the cavity; a connecting layer is arranged on the upper side of the mold sleeve; an air spraying pipe is inserted into the connecting layer; the air spraying pipe penetrates through the top wall of the base body and communicates with an external high-pressure air pump; an annular circulating cavity is formed in the base body; a fixing groove is formed in the outer side of the cavity; and a plurality of groups of heat exchange structures are arranged on one side, close to the mold sleeve, of the fixing groove. The universal blow molding mold has the advantages that the thickness of the inner wall of the plastic subjected to blow molding machining is kept uniform through branch current detection of a bridge circuit, and after forming, the machining is accelerated through the double effects of compressed gas and thermoelectric cooling.

Description

technical field [0001] The invention relates to the technical field of blow molds, in particular to a uniformly processed universal blow mold. Background technique [0002] Blow molding can be divided into extrusion blow molding and injection blow molding. Extrusion blow molding is a method of manufacturing hollow thermoplastic parts. Well-known blow molding objects include bottles, barrels, cans, boxes, and all containers for packaging food, beverages, cosmetics, medicines, and daily necessities. Large blow molded containers are often used for packaging of chemical products, lubricants and bulk materials. Other blow molding products are balls, bellows and toys: [0003] For the blow mold, since the high-temperature raw material is squeezed into the mold opening while it is hot, the compressed air is injected into the parison immediately after the mold is closed, so that the plastic parison is inflated and clings to the inner wall of the mold, so in actual use , it is oft...
