Embodiment 1

[0037] see Figure 1 to Figure 3 , the present invention discloses a blow molding device, comprising: a frame 6, an extrusion mechanism 4, a die head 1, a mold clamping mechanism 2, a blowing mechanism 3, a manipulator 10, a controller 20 (including an electrical system 5, a pneumatic System 7, hydraulic system 9), pipeline system 8, hydraulic servo power supply 11. The controller 20 is respectively connected to the extrusion mechanism 4, the die head 1, the mold clamping mechanism 2, the down blowing mechanism 3, and the manipulator 10 to control the extrusion mechanism 4, the die head 1, the mold clamping mechanism 2, and the down blowing mechanism 3 , Manipulator 10 cooperative action.

[0038] The frame 6 is mainly composed of pillars and frame-shaped beams to support the manipulator 10 and the die head 1. The pillars are formed columnar members, the bottom end of which is provided with a flange for fixed connection with the common base, and the top end is used to support ...

Abstract

The invention discloses a stretching type blow molding machine and a blow molding method thereof. The blow molding machine comprises a machine frame, an extrusion mechanism, a mold head, a mold clamping mechanism, a lower blowing mechanism, a mechanical hand and a controller, wherein the mechanical hand comprises at least one pair of clamping mechanisms, a transmission mechanism and a mechanical hand driving mechanism, and the controller comprises a mechanical hand position driving unit which is used for controlling the downwards pipe blank stretching speed of the mechanical hand so that the moving speed of mechanical hand stretching pipe blanks in the vertical downwards direction of a second guide rail is higher than the free falling speed of the pipe blank forming extrusion, further, the pipe blanks are longitudinally stretched by the mechanical hand in the falling process, and the intensity of products is improved. The stretching type blow molding machine and the blow molding method have the advantages that the mechanical hand is controlled for longitudinally stretching the pipe blanks in the pipe blank dragging process, and molecular chains in the pipe blanks are effectively carded, so the toughness and the intensity of the products are improved, and a product cannot be easily destroyed.

Description

technical field [0001] The invention belongs to the technical field of blow molding, and relates to a blow molding machine, in particular to a stretch blow molding machine; at the same time, the invention also relates to a blow molding method of the above stretch blow molding machine; in addition, the invention also relates to It relates to a product blow-molded by the above-mentioned blow-molding method. Background technique [0002] The existing blow molding machine mainly includes a frame, an extrusion mechanism, a die head, a mold clamping mechanism, a blow down mechanism, and a manipulator. The tube embryo moves downward; the plastic body is blown and attached to the mold cavity of a certain shape by using the wind blown by the machine, so as to make the product. [0003] Among them, the speed at which the manipulator pulls the tube embryo down is usually only along the tube embryo, allowing it to sag freely, and the speed is usually relatively low; the role of the man...
