Abstract
The utility model relates to a can realize that little hydro-cylinder wall and big hydro-cylinder terminal surface port form good sealing performance's zip fastener injection moulding machine, including zip fastener injection moulding machine, be fixed with the sealing washer on the little hydro-cylinder exit end wall that lies in big hydro-cylinder oil cavity among the zip fastener injection moulding machine. The advantages are that: the sealing ring is arranged on the end wall of the inlet and the outlet of the small oil cylinder positioned in the oil cavity of the large oil cylinder in the zipper injection molding machine, so that the movable cavity of the small oil cylinder formed by the small oil cylinder and the large oil cylinder can form a reliable dynamic sealing state, and the reliable work of the small oil cylinder is ensured.
Description
Technical Field
The utility model relates to a can realize that little hydro-cylinder wall and big hydro-cylinder terminal surface port form zipper injection moulding machine of good sealing performance.
Background
CN2475543Y, entitled zipper injection molding machine, mainly comprises a mold opening and closing device, a glue injection device (6) and an oil pressure control system, and is characterized in that the mold opening and closing device adopts an oil pressure composite cylinder structure, and a movable template (3) is fixed at one end of a rod shaft of a large oil cylinder (1) for pressure locking the template; an oil inlet rod matched with the large oil cylinder (1) is sleeved in the other end of the rod shaft of the large oil cylinder (1) to form a small oil cylinder (2) for fast die assembly. The method has the following defects: the other end of the rod shaft of the large oil cylinder (1) is internally sleeved with an oil inlet rod matched with the rod shaft, so that the sealing performance between the small oil cylinders (2) for quickly closing the dies is not ideal.
Disclosure of Invention
The design purpose is as follows: the defects in the background technology are avoided, and the zipper injection molding machine capable of realizing good sealing performance of the small oil cylinder wall and the end face port of the large oil cylinder is designed.
The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses on the basis of earlier all background art of this applicant, through being fixed with the sealing washer on the end wall is imported and exported to the little hydro-cylinder that lies in big hydro-cylinder oil chamber in zip fastener injection moulding machine, make it form good dynamic seal, ensure the reliability of little hydro-cylinder work.
The technical scheme is as follows: a zipper injection molding machine comprises a zipper injection molding machine, wherein a sealing ring is fixed on the end wall of an inlet and an outlet of a small oil cylinder positioned in an oil cavity of a large oil cylinder in the zipper injection molding machine.
Compared with the prior art, the utility model, the sealing washer setting is imported and exported to the little hydro-cylinder that lies in big hydro-cylinder oil chamber among the zip fastener injection moulding machine, makes to constitute little hydro-cylinder activity chamber in little hydro-cylinder and the big hydro-cylinder and can form reliable dynamic seal state, has ensured the reliable work of little hydro-cylinder.
Drawings
FIG. 1 is a schematic view of a zipper injection molding machine.
Fig. 2 is a schematic cross-sectional view of the end face of the seal ring of fig. 1.
Detailed Description
Example 1: reference is made to figures 1 and 2. A zipper injection molding machine comprises a zipper injection molding machine, namely, on the basis of the prior CN2475543Y and the name of the zipper injection molding machine, a sealing ring 01 is fixed on the end wall of an inlet and an outlet of a small oil cylinder 2 positioned in an oil cavity of a large oil cylinder 1 in the zipper injection molding machine. An annular oil cavity 02 is formed in the annular inner part of the sealing ring 01, hydraulic oil is filled in the annular oil cavity through an oil valve (not shown in the figure) communicated with the annular oil cavity. The thickness of the inner ring of the sealing ring forming the built-in annular oil cavity 2 is smaller than that of the outer ring, namely the thickness of the inner wall of the annular oil cavity (02) is smaller than that of the outer wall, so that the sealing surface of the inner ring is in sealing fit with the outer wall of the small oil cylinder 2 under the action of hydraulic oil.
It is to be understood that: although above-mentioned embodiment is right the utility model relates to a making detailed description of characters of thinking, but the description of these characters is only right the utility model relates to a simple description of characters of thinking, it is right not the utility model relates to a restriction of thinking, any not surpass the utility model relates to a combination, increase or the modification of thinking all fall into the utility model discloses a within the protection scope.
Claims (3)
