Abstract
The utility model relates to a special cylinder piston assembly for a hot runner. The special cylinder piston assembly comprises a cylinder body and a piston arranged inside the cylinder body, wherein a seal ring is arranged on the contact surface between the cylinder body and the piston; a vent hole is formed in the cylinder body; the vent hole is vertical to the cylinder body; the seal ring is arranged inside a seal ring groove formed in the piston. The special cylinder piston assembly for the hot runner, which is provided by the utility model, is simple in structure; the vertical vent hole in the cylinder body and the seal ring groove in the piston are easy to machine, short in machining time, and high in efficiency. Thus, the production cost can be reduced.
Description
Technical field
The utility model relates to hot flow path Special cylinder piston component, particularly a kind of simple in structure, be easy to processing hot flow path Special cylinder piston component.
Background technology
In Hot runner Technology field, needle valve type hot runner to be to save material, plastic surface aesthetic, simultaneously internal soundness closely, intensity advantages of higher and being widely used.Along with the development of Hot runner Technology, start needle valve type hot runner system and be widely used in injection molding process.Cylinder is as the critical component of needle valve hot flow passage system, and the optimal design of its structure, directly affects the result of use of TOP-TIP and the manufacturing cost of TOP-TIP.At present in TOP-TIP, conventional cylinder as shown in Figure 1, comprises and is placed in the cylinder block 1 of hot flow path template and is arranged at the piston 4 in cylinder block 1; On described cylinder block 1, be provided with oblique passage 2, difficulty of processing is large, rotate processing, long processing time, and efficiency is low, and cost is high; The contact-making surface of described cylinder block and piston is provided with sealing ring, for the seal groove 3 of described sealing ring is installed, processes at cylinder block 1, and inside groove is too dark, processing difficulties, and long processing time, efficiency is low, and cost is high.
Utility model content
The utility model object be in order to overcome the deficiencies in the prior art, provide a kind of simple in structure, be easy to processing hot flow path Special cylinder piston component.
For achieving the above object, the technical solution adopted in the utility model is: hot flow path Special cylinder piston component, comprise cylinder block and be arranged at the piston in described cylinder block, the contact-making surface of described cylinder block and piston is provided with sealing ring, on described cylinder block, be provided with passage, described passage is perpendicular to described cylinder block, and described sealing ring is arranged in the seal groove of offering on described piston.
Preferably, the afterbody of described cylinder block is provided with boss, and described passage is arranged on the shoulder of described boss.
Preferably, described piston comprises piston crown, piston skirt, the excircle that described seal groove is opened in described piston crown and piston skirt axially on.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The hot flow path Special cylinder piston component of the utility model scheme, oblique passage of the prior art is changed into the passage perpendicular to cylinder block, on the shoulder of described passage perpendicular to cylinder block afterbody boss, make only to need clamped one time just two passages all can be processed, do not need rotation processing, process time is short, and efficiency is high, and then can reduce production costs; To be arranged on piston for the seal groove of sealing ring is installed, compared with process inside groove on cylinder block, same groove depth, handling ease on piston, process time is short, and efficiency is high, and then can reduce production costs.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation of the hot flow path Special cylinder piston component that accompanying drawing 1 is prior art;
Accompanying drawing 2 is the structural representation of hot flow path Special cylinder piston component of the present utility model;
Wherein: 1, cylinder block; 2, oblique passage; 3, seal groove; 4, piston; 5, passage; 6, boss; 7, piston crown; 8, piston skirt.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 2 is hot flow path Special cylinder piston component described in the utility model, comprise cylinder block 1 and be arranged at the piston 4 in described cylinder block 1, described cylinder block 1 is provided with sealing ring with the contact-making surface of piston 4, on described cylinder block 2, be provided with passage 5, described passage 5 is perpendicular to described cylinder block 2, and described sealing ring is arranged in the seal groove 3 of offering on described piston 4; The afterbody of described cylinder block 1 is provided with boss 6, and described passage 5 is arranged on the shoulder of described boss 6; Described piston 4 comprises piston crown 7, piston skirt 8, in the present embodiment, on the excircle of described piston crown 7 and piston skirt 8 is axial, is equipped with a seal groove 3, and two seal grooves can certainly be set.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The hot flow path Special cylinder piston component of the utility model scheme, oblique passage of the prior art is changed into the passage perpendicular to cylinder block, on the shoulder of described passage perpendicular to cylinder block afterbody boss, make only to need clamped one time just two passages all can be processed, do not need rotation processing, process time is short, and efficiency is high, and then can reduce production costs; To be arranged on piston for the seal groove of sealing ring is installed, compared with process inside groove on cylinder block, same groove depth, handling ease on piston, process time is short, and efficiency is high, and then can reduce production costs.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
