A hollow blow molding machine

Abstract

The invention provides a hollow blow molding machine, which includes a frame, an extruding device, an air blowing device and a mold opening and closing device, and also includes an oil wiping device, an edge beating device and a separating device. The extruding device and the blowing device The devices are arranged side by side horizontally, the oil wiping device, the edge beating device and the separating device are arranged vertically from top to bottom and are all located on the side of the blowing device away from the extruding device. The mold clamping device includes a mold base, a secondary mold and an assembly for driving the mold base and a sliding assembly. After the blow molding is completed, the forming mold is opened to obtain a semi-finished product before the blowing rod of the blowing device is moved up, and then the semi-finished product is clamped by the secondary mold, and the blowing rod is then moved up to realize the release of the bottle, and then the edge beating device will The nozzle is cut off to form a finished product, and the nozzle falls from the hopper of the separation device. Finally, the cylinder drives the baffle to overturn, and at the same time, the secondary mold opens to make the finished product fall from the hopper of the separation device to another position. The labor intensity of workers is low and the production efficiency is high.

Description

technical field [0001] The invention relates to a molding device, especially a hollow blow molding machine. Background technique [0002] Hollow blow molding machine is a kind of equipment that sprays out liquid plastic and uses the wind blown out by the machine to blow and attach the plastic body to a mold cavity of a certain shape to make a product. The traditional hollow blow molding machine usually only includes extrusion device, blowing device and mold opening and closing device. The products obtained by using this type of hollow blow molding machine are only semi-finished products, and the nozzle needs to be removed manually or by edge beating equipment (that is, It is the material head) to form the real finished product. At the same time, it is necessary to manually place the spout and the finished product in classification. The labor intensity of the workers is relatively high, and the production efficiency is high. [0003] With the rapid development of the economy...

Problems solved by technology

The traditional hollow blow molding machine usually only includes extrusion device, blowing device and mold opening and closing device. The products obtained by using this type of hollow blow molding machine are only semi-finished products, and the nozzle needs to be removed manually or by edge beating equipment (that is, It is the material head) to form the real finished product. At the same time, it is necessary to manually place the spout and the finished product in classification. The labor intensity of the workers is relatively high, and the production efficiency is high.

[0003] With the rapid development of the economy, the products of packaging bottle manufacturers are also increasing, and the production efficiency of traditional hollow blow molding machines is difficult to meet the production needs of enterprises. In view of this, the applicant has carried out research on the structure of hollow blow molding machines In-depth research led to this case
