Three-dimensional blow molding device

Abstract

The invention relates to the technical field of blow molding devices, in particular to a three-dimensional blow molding device. The three-dimensional blow molding device comprises an extruder and a mold, wherein the extruder is arranged on a platen which can move along X-axis, Y-axis and Z-axis directions; an X-axis motor and a Y-axis motor and transmissions thereof are arranged in the X-axis and Y-axis directions; the transmissions are connected with a platen; a Z-axis motor is arranged in the Z-axis direction of the platen; the Z-axis motor is connected with an elevator rod which is connected to the bottom of the platen; the mold is installed in an inclined way and divided into an upper mold and a lower mold which are respectively arranged on a fixed template and a moveable template, a positioning rod is arranged between the fixed template and the moveable template, and the moveable template has a mold locking cylinder; and all X-axis, Y-axis and Z-axis motors, the extruder and the mold are connected with a programmable logic controller (PLC) control circuit. The device has the advantages that: multi-directional blow molding can be realized in the X-axis, Y-axis and Z-axis directions with the extruder, and influence of random mold displacement on the quality of tube blanks is avoided; 2. the PLC control circuit performs smart control, so production efficiency is improved; and 3. the mold is installed in an inclined way, so materials injected from the mold head are more closed to the mold, a tube blank holder clamps tube blanks and move along with the tube blanks, the tube blanks always fall in the centre of the mold cavity, and thus, adaptability and acceptance rate are improved.

Description

technical field [0001] The invention relates to the technical field of blow molding equipment, in particular to a three-dimensional blow molding equipment. Background technique [0002] In recent years, with the rapid development of hollow blow molding technology, hollow blow molding can not only be used to form various bottles, but also can be used to form containers for daily necessities and industrial products of different sizes and shapes, as well as to form containers of various complex shapes. Hollow industrial parts, such as auto parts can be manufactured through three-dimensional molding. The traditional three-dimensional hollow blow molding process is: first use different molds and blow molding machines to make several sections of products to be produced and parts, respectively cut off the nozzles and process ports of each section of products, and trim each interface and seam line, and then Use a leak tester to test the leaks of each section of the product, and the...

Problems solved by technology

However, the above-mentioned structure has disadvantages: due to the development of mold technology with the development of science and technology, the mold structure is becoming more and more complex, and the volume is getting larger and larger. It is difficult to load the weight of the mold by simply relying on the structure of the moving mold, and the frequent movement of the mold affects the accuracy of the mold blank. The shortcomings of low quality and unstable quality; at the same time, when the mold moves, the billet injected by the extruder die will move freely with the movement of the mold, which is easy to make the finished product irregular and affect the qualified rate of the finished product
