Embodiment Construction

[0018] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] Such as figure 1 , figure 2 As shown, a mold adjusting device is installed on the end face of the mold adjusting template 1 of the injection molding machine. The oil motor 2 is supported and fixed on the adjusting template 1 by the mold adjusting motor seat 10. The first gear 3 (the module is 3.5 and the number of teeth is 20 , the diameter of the indexing circle is 70mm) is connected with the oil motor 2, the middle part of the adjusting plate 1 is provided with a ring gear 4, and the outer side of the ring gear 4 is evenly distributed with four second gears 5 (the module is 3.5, the number of teeth is 53, and the indexing The diameter of the circle is 185...

Abstract

The invention discloses a mold adjusting apparatus of a drawbar type injection molding machine. The apparatus is arranged on an end face of an injection molding machine mold adjusting template. The apparatus comprises a motor, and mold adjusting nuts. The mold adjusting nuts rotate under the driving of the motor. The motor is connected to a first gear. A gear ring is arranged at the center of the end face of the mold adjusting template. The first gear is engaged with the gear ring. Four second gears are uniformly distributed on the outer side of the gear ring. Each second gear is connected to the mold adjusting template through a core shaft arranged at the center of the second gear. The second gears are respectively engaged with the gear ring. A third gear is linked on the outer diameter of each mold adjusting nut. The third gears are engaged with the second gears. Each second gear is positioned between a corresponding third gear and the gear ring. With the mold adjusting apparatus provided by the invention, a driving force chain-transmission characteristic of prior arts is eliminated, and the driving force is transmitted by gear engagement, such that the purpose of mold adjusting is achieved. The transmission precision is high, the transmission process is smooth, the structure is simple, and the installation is convenient. Therefore, the mold adjusting process can be carried out more convenient, and the mold adjusting controlling is more precise.

Description

technical field [0001] The invention relates to a mold adjusting system of an injection molding machine, in particular to the structural design of a mold adjusting device located in a pull rod type injection molding machine. Background technique [0002] It has been more than 50 years since the technological innovation launched the screw type plastic injection molding machine in the 1950s. At present, in the engineering plastics industry, 80% of plastic products are injection molded. In recent years, the increasing demand for injection molding products in industries such as automobiles, construction, household appliances, food, and medicine has promoted the development and improvement of injection molding technology. The sales volume of China's plastic machinery in 2000 was about 7 billion yuan, about 85,000 units in terms of the number of units, of which about 40% were injection molding machines. Judging from major producing countries such as the United States, Japan, Ger...
