Abstract
The utility model discloses an ejecting formula plastic injection mould, it includes annular mold (1) and lies in endocentric air supply (2) that can produce positive negative pressure of annular mold and annular mold, a plurality of through -holes have evenly been seted up on annular mold 's outer loop surface, the adaptation has ball (3) in the through -hole, the rigid coupling has elastic support elements (4) between ball and the annular mold inner ring, elastic support elements is through the circle center extend's to annular mold pipeline (5) and circular coating (6) the intercommunication that surrounds the air supply. The beneficial effects of the utility model are that positive negative pressure through the air supply produces to provide thrust and pulling force to elastic support elements for the ball exposes in by the through -hole or retracts in the annular mold, and the ball exposes annular mold outer loop surface jack -up glass lined when the needs drawing of patterns, thus rapid demoulding.
Description
Technical field
This utility model relates to make the fiber reinforced plastic mold of fiberglass.
Background technology
The manufacture method of existing GRP pipe and glass steel container is usually: at die surface brushing release materials or the parcel mylar of mandrel shape, use hands to stick with paste method or winding method formed glass steel GRP pipe or glass steel container the most thereon, after fiberglass GRP pipe or glass steel container solidify, carry out the demoulding.Wherein, the demoulding is extremely important one procedure in forming process, currently mainly uses mechanical stripping method.After GRP pipe curing molding and seamless between mould, frictional resistance is the biggest, so generally knockout course is complicated, much all use traction machine to draw mould, also need to be equipped with big specification hydraulic means simultaneously and push mould, mould and GRP pipe could be separated.Though this release method safety and stability can realize the demoulding, but the equipment that need to configure is more, and each size pipeline also needs differently configured snap ring.Additionally, heavy gauge tube road or posted sides pipeline knockout course usually cause the motor of traction machine or hydraulic test to damage because resistance is excessive.Chinese utility model patent application number CN201210386667.0 discloses GRP pipe and the manufacture method of glass steel container and mould, including mandrel shape die ontology, described body be coated with corrugated board, described surface plate layer be coated with mylar.Corrugated board is wrapped up at die surface；Mylar is wrapped up again on corrugated board surface；At polyester film surface formed glass steel lining；After frp lining solidifies, frp lining is integral with mould shape, this entirety is rolled on the ground, and corrugated board is crushed under gravity, and frp lining increases with the gap of mould；Mould is extracted out from frp lining, completes the demoulding；But this device cannot ensure the degree that corrugated board is crushed when rolling, and the reliability of the demoulding is the highest, operates the most comparatively laborious.
Utility model content
The technical problems to be solved in the utility model is existing fiber reinforced plastic mold demoulding inconvenience, complex operation, and reliability is the highest, provides a kind of ejecting type fiber reinforced plastic mold for this.
The technical solution of the utility model is: ejecting type fiber reinforced plastic mold, it includes ring mould and is positioned at the source of the gas that can produce positive/negative-pressure that ring mould is concentric with ring mould, the external annular surface of described ring mould uniformly offers some through holes, it is fitted with ball in described through hole, being connected with elastic supporting member for supporting optical member between described ball and ring mould internal ring, described elastic supporting member for supporting optical member is connected with the circular clad surrounding source of the gas by the pipeline extended to the center of circle of ring mould.
Elastic supporting member for supporting optical member described in such scheme is corrugated tube.
Insulation material it is filled with in ring mould described in such scheme.
The beneficial effects of the utility model are that the positive/negative-pressure produced by source of the gas to provide thrust and pulling force to elastic supporting member for supporting optical member, make ball by exposing in through hole or in retraction ring mould, when the needs demoulding, ball exposes ring mould external annular surface jack-up frp lining, thus fast demoulding.

Fig. 1 is this utility model schematic diagram；
In figure, 1, ring mould, 2, source of the gas, 3, ball, 4, elastic supporting member for supporting optical member, 5, pipeline, 6, circular clad.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in Figure 1, this utility model includes ring mould 1 and is positioned at the source of the gas 2 that can produce positive/negative-pressure that ring mould is concentric with ring mould, the external annular surface of described ring mould uniformly offers some through holes, ball 3 it is fitted with in described through hole, being connected with elastic supporting member for supporting optical member 4 between described ball and ring mould internal ring, described elastic supporting member for supporting optical member is connected with the circular clad 6 surrounding source of the gas by the pipeline 5 extended to the center of circle of ring mould.
The ring footpath that the external diameter of ball surrounds with inner ring surface less than ring mould outer ring surface, coating work is not affected in ball retraction ring mould under normality, it is negative pressure by controlling source of the gas, negative pressure is transmitted to elastic supporting member for supporting optical member by pipeline by circular clad, in pulling elastic supporting member for supporting optical member and then plating ball retraction ring mould；When the needs demoulding, control source of the gas is malleation, and malleation is transmitted to elastic supporting member for supporting optical member by pipeline by circular clad, promotes elastic supporting member for supporting optical member and then promotes ball to expose ring mould outer ring surface, support force is provided so that it is disengage with ring mould to the frp lining of ring mould outer ring surface.
In order to ensure the sensitivity that elastic supporting member for supporting optical member responds, elastic supporting member for supporting optical member is preferably corrugated tube.
Cause the lost of life in order to avoid elastic supporting member for supporting optical member is affected by the external environment such as to expand with heat and contract with cold, in ring mould, be preferably filled with insulation material, such as mineral wool, phenol formaldehyde foam etc..
Claims (1)
