A kind of detecting device of the vacuum tightness for detection of the compact disc mold minute surface
Technical field
The present invention relates to a kind of compact disc mold servicing unit, particularly a kind of detecting device of the vacuum tightness for detection of the compact disc mold minute surface.
Background technology
As everyone knows, in compact disc mold, its minute surface all requires to have the function that holds stamper, so each compact disc mold is in process of manufacture, and finished product all needs to test the vacuum tightness of its minute surface, thereby judges whether it has the function that holds stamper.
At present, the vacuum tightness of people's testing optical disk mould mirror surface mainly is to use the suction vacuum plant of injection machine that it is detected, because the startup of whole injection machine and auxiliary device all needs a preheating and stabilization process, so probably need to measure in one hour the vacuum tightness of minute surface.If injection machine has other operation, then can affect the progress of its test minute surface vacuum tightness, and during injection machine work, need all kinds of motors that start more, power consumption is large, has increased the production cost of enterprise.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of simple in structurely, both can detect the vacuum tightness of compact disc mold minute surface, can reduce again the detecting device of energy consumption.
The present invention for the technical scheme that solves its technical matters and adopt is:
A kind of detecting device of the vacuum tightness for detection of the compact disc mold minute surface, comprise vacuum sucker base, the inside of this vacuum sucker base is provided with the vacuum passage that is connected for test product, the upper surface of described vacuum sucker base is provided with a vacuum transmitter seat that includes vacuum generator, be respectively arranged with pressurized air input port, vacuum suction mouth and the exhausr port that is connected with vacuum generator on the described vacuum transmitter seat, described vacuum suction mouth is connected with described vacuum passage sealing, also is connected with vacuum meter on the described vacuum passage.
As improvement of the technical scheme, be provided with the suction inlet that is connected for test product on the described vacuum passage, this suction inlet is arranged on the left surface of vacuum sucker base.
As further improvement in the technical proposal, be provided with the joint that is connected for described vacuum suction mouth on the described vacuum passage, this joint is arranged on the trailing flank of vacuum sucker base, is connected by a sealed tube sealing between described joint and the vacuum suction mouth.
The invention has the beneficial effects as follows: because the present invention adopts the structure that a vacuum transmitter seat is set at vacuum sucker base; with the opening part of test product shutoff at vacuum passage; only need to be filled with pressurized air toward the pressurized air input port of vacuum transmitter seat; can start vacuum generator; people just can measure the vacuum tightness of test product by vacuum meter; the suction vacuum plant that does not need to use in addition injection machine detects the minute surface of compact disc mold; effectively reduced energy consumption; not only reduce the production cost of enterprise, also helped protection of the environment.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is front view of the present invention;
Fig. 2 is the vertical view of the present invention when vacuum meter not being installed.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of detecting device of the vacuum tightness for detection of the compact disc mold minute surface, comprise vacuum sucker base 1, here, preferentially vacuum sucker base 1 is processed into strip, the inside, left side of this vacuum sucker base 1 is provided with for the vacuum passage 10 that is connected with test product, as the preferred embodiments of the present invention, the opening part of these vacuum passage 10 front ends is provided with one for the suction inlet 100 that is connected with test product, this suction inlet 100 is arranged on the left surface of vacuum sucker base 1, above-mentioned suction inlet 100 can so that test product and vacuum passage 10 are tightly connected, prevent gas leakage; The center of this vacuum pipe 10 also offers a hickey 102, be threaded on the described hickey 102 vacuum meter 3 is installed, since between vacuum meter 3 and the hickey 102 for being threaded, therefore, people can pull down vacuum meter 3 at any time from hickey 102, be convenient for people to change or maintenance vacuum meter 3; Therefore the rear end of described vacuum passage 10 also arranges a joint 101 that is connected with its inside, and this joint 101 is arranged on the trailing flank of vacuum sucker base 1, and above-mentioned joint 101 is mutual vertical with described suction inlet 100; The upper surface of described vacuum sucker base 1 is provided with a vacuum transmitter seat 2 that includes vacuum generator, be respectively arranged with pressurized air input port 20, vacuum suction mouth 21 and the exhausr port 22 that is connected with vacuum generator on the described vacuum transmitter seat 2, described vacuum suction mouth 21 is connected with described joint 101 sealings by a sealed tube 4, here the above-mentioned sealed tube 4 preferential rubber hose that adopt.
The course of work of the present invention is as follows:
Minute surface with test product compresses shutoff at suction inlet 100 places of vacuum passage 10 first; and then the pressurized air input port 20 of past vacuum transmitter seat 2 is filled with pressurized air; at this moment; vacuum generator in the vacuum transmitter seat 2 starts; vacuum suction mouth 21 places begin vacuum passage 10 is inhaled vacuum; therefore people namely can measure the vacuum tightness of test product by vacuum meter 3; the described pressurized air that is filled with is drained from the exhausr port 22 of vacuum transmitter seat 2; because when detecting device of the present invention is surveyed vacuum tightness; only need to be filled with pressurized air toward the pressurized air input port of vacuum transmitter seat; can start vacuum generator; people just can measure the vacuum tightness of test product by vacuum meter; the suction vacuum plant that does not need to use in addition injection machine detects the minute surface of compact disc mold; effectively reduced energy consumption; not only reduce the production cost of enterprise, also helped protection of the environment.
The above only is preferential embodiment of the present invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
