Problems solved by technology
Disadvantages of the mechanism: 1) The design and machining accuracy of the cam flange or groove profile of the cylindrical space cam is high, the installation and positioning of the cam is difficult, and the rotor is easily stuck; 2) The contact surface between the rotor and the cylindrical space cam profile is easy to form Point contact, large compressive stress, easy damage to the rotor or easy wear on the cam surface; 3) limited by the space size, usually the pressure angle of the cam in the cylindrical space is too large, similarly, the rotor is easy to damage or the cam surface is easy to wear

Embodiment Construction
[0029] The technical solutions of the present invention will be further described below in combination with specific embodiments and accompanying drawings.
[0030] see Figure 1-4 As shown, this embodiment provides a full-link type bottom mold lifting mechanism for single mold opening of blow molding machine, which includes a mold frame bracket 1, which is connected to the mold frame bracket 1 and can swing around the axis line of the first shaft 2. The bottom mold support 3 on the top, the first slide block 4 that can be lifted on the bottom mold support 3, and the second slide block 5 that can slide along the first direction and is located on the bottom mold support 3. The first shaft 2 extends in a vertical direction.
[0031] The movable side mold and the fixed side mold (not shown in the figure) are respectively installed on the formwork bracket 1, and the bottom mold bracket 3 is driven to swing by an independent drive mechanism or a linkage mechanism linked to the mov...

The invention discloses a full connecting rod type bottom die lifting mechanism for a single open die of a bottle blowing machine. The full connecting rod type bottom die lifting mechanism comprises a die frame support, a bottom die support connected to the die frame support in a swinging mode, a first sliding block arranged on the bottom die support in a lifting mode, a second sliding block which is arranged on the bottom die support and is capable of sliding in the first direction, a connecting rod mechanism connected between the second sliding block and the first sliding block, and a first connecting rod with the two ends rotationally connected with the die frame support and the second sliding block correspondingly. The connecting rod mechanism comprises a second connecting rod, a third connecting rod, a fourth connecting rod and a fifth connecting rod; one end of the second connecting rod is rotationally connected to the second sliding block; one end of the third connecting rod is rotationally connected to the other end of the second connecting rod; one end of the fourth connecting rod is rotationally connected to the bottom die support; the two ends of the fifth connecting rod are rotationally connected with the first sliding block and the other end of the fourth connecting rod correspondingly; and the third connecting rod is fixedly connected to the fourth connecting rod. The rotating planes of the second connecting rod, the third connecting rod, the fourth connecting rod and the fifth connecting rod are parallel to a first plane. The bottom die lifting mechanism can accurately control the movement rule of a bottom die.
Description
technical field [0001] The invention relates to the technical field of bottle blowing, in particular to a full-link bottom mold lifting mechanism for a single mold opening of a bottle blowing machine. Background technique [0002] Blow molding machine is the key equipment for producing plastic bottles for various liquid packaging. Each process of the bottle blowing machine has strict requirements and high requirements for mutual cooperation, especially for the synchronous control of the bottom mold swing and lifting movement of the single mold opening. [0003] In the prior art, the linkage between the bottom mold swing and the lifting motion is generally realized through a cylindrical space cam mechanism. Mechanism advantages: simple mechanism, few moving parts. Disadvantages of the mechanism: 1) The design and machining accuracy of the cam flange or groove profile of the cylindrical space cam is high, the installation and positioning of the cam is difficult, and the roto...
