Nozzle shearing equipment

Abstract

The invention provides water gap shearing equipment, comprising a main body machine case and a main body frame, wherein the main body frame comprises an upper platform and a lower platform; a linear lead rail and a horizontal propelling cylinder are arranged on the lower platform; a plastic product positioning device is arranged on the linear lead rail; the horizontal propelling cylinder is used for propelling the plastic product positioning device; a main cutting cylinder and an upper knife rest connected with the main cutting cylinder are arranged on the upper platform; at least two guide shafts for shearing and positioning and a guide post for guiding the upper knife rest to move up and down are arranged on the upper knife rest; the main body frame is provided with an adjusting screw for adjusting change of a front position between the main body machine case and the main body frame; at least one plastic product positioning die is arranged on the plastic product positioning device; a lower auxiliary shearing knife is arranged on the positioning die; at least one knife tackle positioning template is arranged below the upper knife rest; and an upper shearing knife tackle is arranged on the knife tackle positioning template. Thus, the cost can be reduced; and the shearing efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a nozzle shearing device. Background technique [0002] Both the nozzle punching device and the nozzle shearing equipment have started to be used in the field of injection molding. Most of the existing nozzle punching devices are made according to the punching position of the plastic product, referring to the way of metal stamping. The cutting device is completely positioned, and the cut plastic parts have to be taken out manually, which is unsafe and the production efficiency is not high; the cutting of the nozzle is to cut the plastic parts by the upper and lower fixed knives, and the position of the knives has been fixed. Adjustment, the design of the knife group cannot perform shear correction on the offset of the plastic part, and cannot adapt to the shear position offset caused by the deformation of the plastic product, which often causes the shear position to shift and...

Problems solved by technology

[0002] Both the nozzle punching device and the nozzle shearing equipment have started to be used in the field of injection molding. Most of the existing nozzle punching devices are made according to the punching position of the plastic product, referring to the way of metal stamping. The cutting device is completely positioned, and the cut plastic parts have to be taken out manually, which is unsafe and the production efficiency is not high; the cutting of the nozzle is to cut the plastic parts by the upper and lower fixed knives, and the position of the knives has been fixed. Adjustment, the design of the knife group cannot perform shear correction on the offset of the plastic part, and cannot adapt to the shear position offset caused by the deformation of the plastic product, which often causes the shear position offset and the shear surface is not smooth; the position of the tool deviates The time adjustment is uncontrollable, and it is inconvenient to replace the tool when it is damaged. The actual production efficiency is not high, and the effect is very unsatisfactory. It is very inconvenient to adjust the positioning of the parts; generally, two-dimensional moving cutters are used for cutting processing. The cutting tool does not have the position correction when the plastic product is deviated. When the plastic part is deformed, the cutting position of the nozzle will deviate accordingly. The surface is uneven or the plastic product is damaged; when there are many nozzle positions that need to be cut, the two-dimensional movement method takes a long time to cut, and the efficiency is not high, and the automatic separation of the plastic parts is not convenient to realize, and the processing volume of the plastic parts is not large. Easy to set

[0003] In summary, the existing nozzle shearing equipment obviously has inconvenience and defects in actual use, so it is necessary to improve it
