Foam forming machine with stable and reliable moving and locking of movable mold

Abstract

The invention discloses a foam forming machine with stable and reliable moving and locking of a movable mold. The foam forming machine comprises a support, a fixed mold, the movable mold, a movable mold moving driving mechanism and a mold locking mechanism; the movable mold moving driving mechanism comprises a pair of first ball screws mounted at the top of the support and a pair of first servo motors for driving the first ball screws to act; and the mold locking mechanism comprises two mold locking pull rods located at the two sides of the fixed mold, two mold locking pull blocks matched with the mold locking pull rods, two pull rod driving assemblies for driving the mold locking pull rods to act and two pull rod locking assemblies matched with the mold locking pull rods. By means of the foam forming machine, the moving stability of the movable mold is high, the mold opening and closing stability and reliability are guaranteed, and the product forming effect and the product quality are guaranteed; all parts are long in service life and do not need to be replaced frequently, the production cost is reduced, and the production efficiency is improved; and the mold locking pull rods are locked after being lifted, the mold locking pull rods can be rapidly tensioned, rapid and stable mold locking is achieved, the fault occurrence rate is low, the maintenance cost is low, power transmission is rapid, and the mold locking efficiency is ensured.

Description

technical field [0001] The invention relates to a foam molding machine, in particular to a foam molding machine with stable and reliable mold transfer and locking. Background technique [0002] The mold shifting and moving drive mechanism of the existing foam molding machine usually uses a motor to drive the mold to move back and forth through the synchronous belt transmission assembly. This structure is greatly affected by the quality of the synchronous belt transmission assembly, especially in high-pressure and high-temperature environments. The transmission stability of the transmission components is not guaranteed, which affects the stability of mold opening and closing, affects the product molding effect, and thus affects product quality; and the service life of the timing belt is short, requiring frequent maintenance and replacement, which increases production costs. reduce production efficiency; [0003] The clamping mechanism of the existing foam molding machine usu...

[0002] The mold shifting and moving drive mechanism of the existing foam molding machine usually uses a motor to drive the mold to move back and forth through the synchronous belt transmission assembly. This structure is greatly affected by the quality of the synchronous belt transmission assembly, especially in high-pressure and high-temperature environments. The transmission stability of the transmission components is not guaranteed, which affects the stability of mold opening and closing, affects the product molding effect, and thus affects product quality; and the service life of the timing belt is short, requiring frequent maintenance and replacement, which increases production costs. reduce production efficiency;

[0003] The clamping mechanism of the existing foam molding machine usually adopts hydraulic power components to tighten or push the mold to move. This structure is greatly affected by the hydraulic power components. The failure rate of the hydraulic power components is relatively high, and the maintenance cost is high. Moreover, the power transmission of the hydraulic power component is relatively slow, which affects the clamping speed and reduces the production efficiency; at the same time, the hydraulic clamping structure is adopted, and there are many problems that the clamping pressure of the machine is not maintained, and it is easy to leak oil, causing oil pollution in the workshop
