Abstract
The utility model foaming mould exhaust structure, including the multiple screw thread gas vents being arranged in upper mold and the screw thread pin being arranged in each screw thread gas vent, screw thread pin outer surface is equipped with the external screw thread matched with the internal screw thread of screw thread gas vent inner wall, screw thread pin is equipped with the regular hexagon groove that can be matched with allen wrench in upper center, is equipped on the downside of regular hexagon groove and is connected to regular hexagon groove bottom end and runs through the stepped hole of screw thread pin lower end surface.Since multiple screw thread gas vents being arranged in upper mold, screw thread pin is set in each screw thread gas vent, gas in foaming mould can be by the stepped hole discharge in the middle part of the thread pitch and screw thread pin between screw thread gas vent and screw thread pin, thread pitch and stepped hole are not easy all to be plugged, facilitate smooth exhaust, when exhaust passage blocking, disassembly screw thread pin is easy for by allen wrench, cleaning is convenient.
Description
Technical field
The utility model relates to a kind of exhaust structure of mold, in particular to a kind of foaming mould exhaust structure.
Background technique
In low pressure foam production technique, in order to guarantee the air-tightness of shaped article, need in the upper mold of foaming mould
Exhaust structure is set, and present foaming mould is that multiple straight hole gas vents are arranged in upper mold, is easy blocking after foamed material curing
Gas vent, exhaust hole plug inconvenience mold inner-cavity exhaust are easy to influence product quality, and need often cleaning gas vent, straight hole
Gas vent is inconvenient to clear up.
Summary of the invention
The purpose of this utility model is in view of the above-mentioned drawbacks of the prior art, providing one kind is not easy blocking, exhaust
Good, also easy to clean foaming mould exhaust structure.
The utility model to achieve the above object the technical solution adopted is that: a kind of foaming mould exhaust structure, including set
The screw thread pin setting multiple screw thread gas vents in upper mold and being arranged in each screw thread gas vent, screw thread pin outer surface are set
There is the external screw thread matched with the internal screw thread of screw thread gas vent inner wall, screw thread pin is equipped in upper center can be with allen wrench
The regular hexagon groove matched, regular hexagon groove downside, which is equipped with, to be connected to regular hexagon groove bottom end and runs through screw thread pin
The stepped hole of lower end surface.
The further technical solution of the utility model is: stepped hole on the downside of the hexagonal indentations be upper end aperture it is big and
The small stepped hole in lower end aperture.
The utility model foaming mould exhaust structure has the following beneficial effects: since multiple screw thread rows being arranged in upper mold
Stomata, screw thread pin is arranged in each screw thread gas vent, and the gas in foaming mould can pass through screw thread gas vent and threaded
Stepped hole discharge in the middle part of thread pitch and screw thread pin between son, thread pitch and stepped hole are not easy all to be plugged, side
Just smooth exhaust is easy for disassembly screw thread pin by allen wrench, cleaning is convenient when exhaust passage blocking.
The utility model foaming mould exhaust structure is further described with reference to the accompanying drawings and examples.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model foaming mould exhaust structure；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is enlarged view at the A of Fig. 2；
Drawing reference numeral explanation: 1- upper mold, 2- screw thread gas vent, 3- screw thread pin, 4- foaming model cavity, 5- regular hexagon are recessed
Slot, 6- stepped hole.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model foaming mould exhaust structure, including the multiple screw threads being arranged in upper mold 1
Gas vent 2 and the screw thread pin 3 being arranged in each screw thread gas vent 2, screw thread gas vent 2 through upper mold 1 template and with it is outer
Boundary's connection.3 outer surface of screw thread pin is equipped with the external screw thread matched with the internal screw thread of 2 inner wall of screw thread gas vent, and screw thread pin 3 exists
Upper center is equipped with the regular hexagon groove 5 that can be matched with allen wrench, is equipped with and positive six side on the downside of regular hexagon groove 5
5 bottom end of connected in star is connected to and runs through the stepped hole 6 of 3 lower end surface of screw thread pin, and the stepped hole 6 on the downside of the hexagonal indentations is
Upper end aperture is big and stepped hole 6 that lower end aperture is small.
When installation mold, screw thread pin 3 is mounted in each screw thread gas vent 2 by allen wrench, is being foamed
When mold forming foamed material, the gas that foams in model cavity 4 by thread pitch between screw thread gas vent 2 and screw thread pin 3 and
The stepped hole 6 at 3 middle part of screw thread pin is discharged, and after multiple contoured foam product, when exhaust passage blocking, passes through allen wrench
It is easy for disassembly screw thread pin 3, cleaning is convenient.
Above embodiments are only the preferred embodiment of the utility model, and the structure of the utility model is not limited to above-mentioned implementation
The form enumerated of example, any modification made within the spirit and principle of the present invention, equivalent replacement etc. should all include
It is within the protection scope of the utility model.
