Technical field
The utility model relates to a kind of high-speed injection molding machine, specifically a kind of glue injection oil cylinder end cap of high-speed injection molding machine.
Background technology
Injection molding machine injection action affects very large on injection machine performance and quality of item, especially on high speed machine, can injection speed directly affects entire machine get qualified products.Wherein injection molding machine injection action is directly driven by injection cylinder, and injection cylinder comprises cylinder body and glue injection oil cylinder end cap.
At present, the main steel part of glue injection oil cylinder end cap is processed, and general blank source has two kinds, and wherein one is directly cut out by steel plate or forged into blank shape, and then carry out fine finishining, stock utilization is not high.As shown in Figure 5-Figure 7, it is now widely used glue injection oil cylinder lid, owing to considering material and cost, the thickness of glue injection oil cylinder lid is restricted, during design oil cylinder port, the oilhole Y of a vertical hydraulic fluid port X and a transverse direction can only be, owing to being subject to structure restriction, horizontal oilhole Y diameter can not do greatly, at this moment can only make profiled holes to meet with by the shape of horizontal oilhole Y.This kind of design is violent in horizontal oilhole Y changes of section, it is caused to be easy to form throttling, add resistance, there is the larger pressure loss, accelerate when being unfavorable for high speed injection, and when directly forwarding horizontal oilhole Y to by vertical hydraulic fluid port X, namely hydraulic oil is when from Fig. 7, Z haircut direction is passed through, hydraulic oil at a high speed on the corner easily forms eddy current and spins, and causes hydraulic system abnormal sound, can not meet the function demand of current high speed machine.Therefore, further improvement is necessary.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, dependable performance, and asphalt channel is large, and the pressure loss is little, and dismounting is quick, changes the glue injection oil cylinder end cap of high-speed injection molding machine easily, to overcome weak point of the prior art.
The glue injection oil cylinder end cap of a kind of high-speed injection molding machine designed by this object, comprise glue injection oil cylinder lid main body and seal sleeve of piston rod, it is characterized in that: glue injection oil cylinder lid main body adopts spheroidal graphite cast-iron casting to form and be provided with in side, center and installs room, seal sleeve of piston rod adopts steel part to process and is arranged on and installs on room, and coordinates fixing with glue injection oil cylinder lid main body by hold-down screw.
Described glue injection oil cylinder lid main center place's opposite side is provided with the horizontal oil cylinder chamber passed through for hydraulic oil and corresponding horizontal oil cylinder chamber is provided with longitudinal oilhole, is provided with hydraulic oil cushion chamber between longitudinal oilhole and horizontal oil cylinder chamber; Described horizontal oil cylinder chamber, hydraulic oil cushion chamber and longitudinal oilhole are interconnected.
Described horizontal oil cylinder chamber and hydraulic oil cushion chamber are ringwise and water conservancy diversion inclined plane is provided therebetween.
The inwall of described seal sleeve of piston rod is provided with piston rod packing groups of slots and is connected with piston rod packing by arranging sealing ring in piston rod packing groups of slots.
The outer wall of described seal sleeve of piston rod is provided with O type circle sealed groove and is tightly connected by the installation room arranged in O type circle and glue injection oil cylinder lid main body on O type circle sealed groove.
Described glue injection oil cylinder lid main body adopts spheroidal graphite cast-iron casting form and be provided with some reinforcements thereon, and the upper end of glue injection oil cylinder lid main body is provided with valve plate or Pipe installing platform, and valve plate or Pipe installing platform are provided with longitudinal oilhole.
Described piston rod packing is set on the side of glue injection oil cylinder lid main body, the opposite side of glue injection oil cylinder lid main body is provided with positioning spigot and o-ring groove, glue injection oil cylinder lid main body is located by positioning spigot and high-speed injection molding machine and mutually by arranging sealing ring and high-speed injection molding machine is tightly connected on o-ring groove, glue injection oil cylinder lid main body is also provided with installing hole and passes through to arrange securing member on installing hole and high-speed injection molding machine is connected.
The utility model, by the improvement of said structure, adopts separation design scheme, forms glue injection oil cylinder end cap by glue injection oil cylinder lid main body and seal sleeve of piston rod.Wherein glue injection oil cylinder lid main body adopts spheroidal graphite cast-iron casting to form, and the center has been emptied and installed room and horizontal oil cylinder chamber, casts glue injection oil cylinder lid main body simultaneously and adopts reinforcing rib structure, therefore greatly can save material, improve stock utilization; Seal sleeve of piston rod adopts plain steel to process, because each seal groove requires that machining accuracy is high, this part is separated from glue injection oil cylinder end cap and arranges in addition, part entirety is made to diminish, lighten, machining accuracy easily ensures, inspection each several part groove dimensions is also easier, ensure that the qualification rate of part widely; Seal sleeve of piston rod and the split of glue injection oil cylinder lid main body arrange and bring convenience machine later period maintenance in addition, because seal belongs to consumable accessory, fault rate is higher, can wear and tear after practicality is long-time causes sealing property to decline, only seal sleeve of piston rod need be pulled down from glue injection oil cylinder lid main body when seal changed by needs, without the need to pulling down whole glue injection oil cylinder end cap, avoiding prior art needs whole glue injection oil cylinder lid to pull down from machine to change, and causes dismounting to keep in repair the problem wasted time and energy.It has simple and reasonable, dependable performance, and asphalt channel is large, and the pressure loss is little, and dismounting is quick, changes the features such as convenient, practical.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
See Fig. 1-Fig. 4, the glue injection oil cylinder end cap of this high-speed injection molding machine, comprise glue injection oil cylinder lid main body 1 and seal sleeve of piston rod 2, glue injection oil cylinder lid main body 1 adopts spheroidal graphite cast-iron to cast and forms and be provided with some reinforcements 1.4 thereon, and the center side is provided with installs room 1.8, seal sleeve of piston rod 2 adopts steel part to process and is arranged on and installs on room 1.8, and is coordinated fixing with glue injection oil cylinder lid main body 1 by hold-down screw 3.
The upper end of glue injection oil cylinder lid main body 1 is provided with valve plate or Pipe installing platform 1.1, valve plate or Pipe installing platform 1.1 are provided with longitudinal oilhole 1.2, glue injection oil cylinder lid main body 1 center opposite side is provided with the horizontal oil cylinder chamber 1.9 passed through for hydraulic oil, corresponding and be provided with hydraulic oil cushion chamber 1.5 between horizontal oil cylinder chamber 1.9 with longitudinal oilhole 1.2; Described horizontal oil cylinder chamber 1.9, hydraulic oil cushion chamber 1.5 and longitudinal oilhole 1.2 are interconnected; Wherein, horizontal oil cylinder chamber 1.9 and hydraulic oil cushion chamber 1.5 are ringwise and water conservancy diversion inclined plane 1.10 is provided therebetween.As shown in Figure 4, hydraulic oil passes through along B haircut direction, hydraulic oil at a high speed passes through between horizontal oil cylinder chamber 1.9, hydraulic oil cushion chamber 1.5 and longitudinal oilhole 1.2, the hydraulic oil that efficiently avoid prior art easily forms eddy current by corner and spins, and causes the phenomenon of hydraulic system abnormal sound.
