Embodiment 1

[0040] Embodiment 1, with reference to figure 1 , a one-step extrusion blow molding pot process special molding extrusion molding blow mold, including a two-part mold mold 3 and a forming pot body cavity 5 on it, and the mouth of the forming pot body cavity 5 passes through a connecting ring Die cavity 1 communicates with pot lid die cavity 4. The cavity 5 of the forming pot body communicates with the cavity of the handle.

[0041] The connecting ring cavity 1 communicates with the pot lid cavity 4 and the kettle body cavity 5 through the pot lid notch cavity and the pot mouth notch cavity. In order to make a qualified product of the pot lid and the pot body at the same time, a double incision with a vertical angle of less than 40 degrees is designed between the pot lid and the spout. Finally, cut off the connecting ring in the middle along the incision, and the pot lid can be properly fastened on the spout, thus ensuring the integrity of the two products. And the pot lid a...

Embodiment 2

[0043] Embodiment 2, with reference to figure 2 , a one-step extrusion blow molding pot process special molding extrusion molding blow mold, including a two-part mold mold 3 and a forming pot body cavity 5 on it, and the mouth of the forming pot body cavity 5 passes through a connecting ring Die cavity 1 communicates with pot lid die cavity 4. There is no handle cavity on the cavity of the forming pot body. The rest are the same as embodiment 1.

Embodiment 3

[0044] Embodiment 3, a kind of one-step extruding and blowing into the product that pot technology produces, comprises forming kettle blank, cleans and shapes the flash overflow, burr etc. of this molding kettle blank parting surface place, cuts off this molding kettle blank simultaneously The connecting ring connecting the pot lid and the pot body makes the pot lid and the mouth of the pot body snap together to form the plastic pot product with no color difference in each part of the present invention.

Abstract

The invention discloses a one-step extrusion-blown molding pot forming technology. According to the one-step extrusion-blown molding pot forming technology, a mold pressing forming technology and an extrusion-blown molding technology are combined into a whole. An air inlet core bar of the extrusion-blown molding technology is also a male mold of the mold pressing forming technology. A pot cover, a spout and a pot body of a formed pot can be formed in an extrusion-blown molding mode with one mold in one step. The technological advance of the hollow forming technology field is promoted, the complex and refine development tendency of current hollow products is met, and more complex products can be developed through the idea.

Description

technical field [0001] The present invention relates to the technical field of compression molding extrusion blow molding production technology, specifically refers to the one-step extrusion blow molding pot process and its special molding extrusion molding blow molding mold, especially refers to the simultaneous production of pot lid, spout and pot body in one mold Advanced compression molding extrusion blow molding process and special compression extrusion blow molding mold. Background technique [0002] Extrusion hollow blow molding process is to blow compressed air into the parison melted by the extruder to make it expand horizontally. Under the action of internal pressure, the parison is tightly attached to the surface of the mold cavity, and after cooling, it becomes a hollow product after demoulding. [0003] The extrusion hollow blow molding process usually produces products with relatively simple shapes, usually bottles, such as beverage bottles, cosmetic bottles, ...
