Abstract
The utility model discloses a hot runner mold's thermal -insulated sealing device, thermal -insulated sealing device includes a thermal -insulated sealing washer, is somebody's turn to do the elastic support elements of the thermal -insulated embedded annular structure of sealing washer, and this elastic support elements's rampart department has seted up a plurality of elasticity fabrication holes. Thermal -insulated sealing device will the free accommodation all around of hot mouth because of the device when injection forming, and the heat of protecting hot mouth can not lead to the heat to run off because of the inside cooling system's of mould forming module influence. The device's elastic support elements to open flexible fabrication hole on elastic support elements, the purpose of opening the elasticity fabrication hole is the elasticity function that increases elastic support elements, makes it to have more superior elastic expansion function when moulding plastics. Elastic support elements's good flexible function, what compensatied that accumulative error that a plurality of thermal -insulated sealing device that many types of chamber mould prepared caused because of processing, assembly difference causes is sealed not tight not enough, and hot mouth is sealed tight with the die cavity junction surface.
Description
Technical field
The utility model relates to hot runner mould machinery manufacturing technology field, and specifically one is for hot runner mould
Heat insulation sealing device.
Background technology
Each die cavity of hot runner mould, hot mouth is all configured with heat insulation sealing device.Traditional multi-cavity hot runner mould,
Heat insulation sealing device only has heat-insulating and sealing or elastic supporting member for supporting optical member or a combination of both, and elastic supporting member for supporting optical member does not has elastic process hole.
Because every secondary mould has the heat insulation sealing device identical with die cavity number, these sealing devices are formed by machining, and processing is by mistake
The accumulated errors such as difference, die assembly error, injection moulding process is accomplished by heat insulation sealing device and has good elastic telescopic function, comes
Make up because the shaping of injection-molded work may be adversely affected by these errors, as injection poorly sealed causes hot melting plastic to escape towards
The gap of mould.Traditional heat insulation sealing device is poor because of telescopicing performance, is difficult to eliminate this device at mechanical processing process, mould dress
Join the impact on injection moulding process of accumulated error that process causes, thus cause injection precision bad, injection-molded work to be difficult to control to,
Even escape towards other position of mould because of hot melt plastic from poorly sealed die clearance, cause burn failure.
Summary of the invention
The purpose of this utility model is to provide the heat insulation sealing device of a kind of hot runner mould, and this device coordinates at hot-fluid
On the hot mouth of road mould, when injection, i.e. protect the heat of mold hot mouth position, the sealing at mold hot mouth can be kept again
Can, prevent the glue that overflows, and then ensure the precision of injection-molded work.Overcome defect and deficiency that above-mentioned work on hand platform exists.
To achieve these goals, the technical solution of the utility model is: the heat insulation sealing device of a kind of hot runner mould,
It is characterized in that: described heat insulation sealing device includes a heat-insulating and sealing circle, the elasticity of the embedded circulus of this heat-insulating and sealing circle
Support member, offers some elastic process holes at the ring wall of this elastic supporting member for supporting optical member.
The utility model discloses the heat insulation sealing device of a kind of hot runner mould, when injection molded, because this device will
Hot mouth surrounding encases, and protects the heat of hot mouth will not cause heat stream because of the impact of the cooling system of mould molding inside modules
Lose.The elastic supporting member for supporting optical member of this device, and on elastic supporting member for supporting optical member, open flexible fabrication hole, the purpose opening elastic process hole is
Increase the spring function of elastic supporting member for supporting optical member, be allowed to that when injection there is more superior elastic telescopic function.Elastic supporting member for supporting optical member
Good Telescopic, compensate for the accumulation that multiple heat insulation sealing devices of multiple-cavity mold preparation cause because of processing, assembling difference
The poorly sealed deficiency that error causes, hot mouth and die cavity junction surface seal tight.Not only ensure that injection-molded work, improve
Injecting products quality stability, and improve mold use efficiency and service life, reduce mould maintenance cost, for enterprise
Industrial belt carrys out bigger economic benefit.

Detailed description of the invention
With reference to the accompanying drawings, the utility model is further described below.
The utility model is the heat insulation sealing device of a kind of hot runner mould, and it is different from prior art and is: described every
Apparatus for heat sealing includes a heat-insulating and sealing circle 1, the elastic supporting member for supporting optical member 3 of the embedded circulus of this heat-insulating and sealing circle 1, this elasticity
Some elastic process holes 2 are offered at the ring wall of support member 3.This sealing device is as the important composition portion of multi-cavity hot runner mould
Point, it coordinates with the hot mouth of hot runner mould, and playing injection is thermal insulation protection and sealing function.
In the specific implementation, described heat-insulating and sealing circle 1 is high-temperature resistance plastice material, is used for adapting at the hot mouth of hot runner mould
Hot environment.
In the specific implementation, described elastic supporting member for supporting optical member 3 is the metal material with elastic nature, such as steel alloy SKD61,
High-speed steel SKH51.
In the specific implementation, described elastic supporting member for supporting optical member 3 entirety structure in the form of a ring, offer at the upper limb of this elastic supporting member for supporting optical member 3
Some breach 4, described breach 4 is equally distributed at the upper limb of elastic supporting member for supporting optical member 3, breach act on suitable spring former
Reason, makes support member have bigger shrink space when shrinking.
In the specific implementation, described elastic process hole 2 can be octagon hole, hexagonal hole, pentagon hole, quadrilateral hole,
Tri-angle-holed or W shape hole, the unlatching in elastic process hole, make elastic supporting member for supporting optical member have the Telescopic that more top grade is good, thus have
Better seal effect.
In the specific implementation, above-mentioned quadrilateral hole and tri-angle-holed in, the adjacent joining place between the hole wall of both sides is one
Transition plane 5.
