Abstract
The utility model provides an evacuating device, which comprises an upper die, a lower die, a first open cavity, a second open cavity and an exhausting mechanism. The lower die is used for being fittingly assembled with the upper die, the integral upper die is positioned in the first open cavity, the integral lower die is positioned in the second open cavity, when the lower die moves towards the upper die, the first open cavity and the second open cavity are staggered mutually and are tightly attached to each other to form a sealed cavity, and the exhausting mechanism is used for exhausting air in the cavity.
Description
Technical field
The utility model relates to vacuum extractor, relates in particular to the vacuum extractor on a kind of LED of being used for compression forming equipment.
Background technology
By use LED compression forming device fabrication LED product the time, the specific glue that is used for making the LED lens to be poured into the mould of LED compression forming equipment, matched moulds by mould makes that the glue solidifies forms fixed shape, but mould is understood the glue that make because of the intervention of air and problems such as bubble, burr, air spots cunning occurred in the process of matched moulds, and then has influence on the quality of LED lens at last.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of vacuum extractor.
The utility model provides a kind of vacuum extractor, comprise patrix and be used for carrying out the counterdie that matched moulds cooperates with described patrix, this vacuum extractor also comprises the first open type cavity, the second open type cavity, described patrix integral body is positioned at the described first open type cavity, and described counterdie integral body is positioned at the described second open type cavity; Described counterdie carries out when mobile to described patrix, and described first open type cavity and the described second open type cavity stagger mutually and fit tightly the chamber that forms sealing; This vacuum extractor also comprises the extraction sector that is used for the extraction of the air in the described chamber.
As further improvement of the utility model, the opening shape of the opening shape of the described first open type cavity, size and the described second open type cavity, measure-alike, the described first open type cavity position and the second open type cavity are staggeredly located out.
As further improvement of the utility model, this vacuum extractor also comprises the driving mechanism that the described counterdie of driving is in vertical motion, and described driving mechanism is installed on the below of described counterdie.
The beneficial effects of the utility model are: because patrix integral body is positioned at the described first open type cavity, counterdie integral body is positioned at the described second open type cavity, after so the first open type cavity and the second open type cavity form the chamber of sealing, upper die and lower die just can be finished mould assembling action, and will be in the chamber that forms sealing by extraction sector with the air sucking-off in the chamber, making does not have air in matched moulds process middle chamber, so glue can not produce bubble when matched moulds, guaranteed the quality of LED lens.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of vacuum extractor, comprise patrix 1 and be used for carrying out the counterdie 2 that matched moulds cooperates with described patrix 1, this true evacuator also comprises the first open type cavity 3, the second open type cavity 4, described patrix 1 integral body is positioned at the described first open type cavity 3, and described counterdie 2 integral body are positioned at the described second open type cavity 4; Described counterdie 2 carries out when mobile to described patrix 1, and the described first open type cavity 3 staggers mutually with the described second open type cavity 4 and fits tightly the chamber that forms sealing; This vacuum extractor also comprises the extraction sector that is used for the extraction of the air in the described chamber.
The opening shape of the opening shape of the described first open type cavity 3, size and the described second open type cavity 4, measure-alike, the described first open type cavity, 3 positions and the second open type cavity 4 are staggeredly located out.
This vacuum extractor also comprises the driving mechanism 5 that the described counterdie of driving is in vertical motion, and described driving mechanism 5 is installed on the below of described counterdie.
During work, driving by driving mechanism 5 makes the second open type cavity 4 and the first open type cavity 3 form the chamber of sealing, continuation by driving mechanism 5 drives again, make counterdie 2 and patrix 1 matched moulds together, and in the process of matched moulds, the air in the chamber is extracted out by vacuum device, make chamber be in vacuum state, the glue that is arranged in counterdie 2 so just bubble can not occur in the matched moulds process.
Because after the described first open type cavity 3 forms the chamber of sealing with the described second open type cavity 4, described patrix 1 carries out matched moulds again with described counterdie 2, and in the time of matched moulds by extraction sector with the air sucking-off in the chamber, make and do not have air in the chamber, so glue can not produce bubble when matched moulds, guaranteed the quality of LED lens.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
