Detailed Description
The invention is further described below with reference to the following figures and specific examples.
As shown in fig. 1 to 6, the mixing section structure of the extruder comprises a base 1, a cover plate 2, a cover opening mechanism 3 and a forming die 5. The base 1 is provided with a die cavity with an upper opening, and the outer side of the die cavity is provided with a water heating pipe. Because the heating temperature of the foaming body is usually within 100 ℃, in order to enable the foaming body to be uniformly foamed and molded in the molding cavity, the water heating pipe adopts a water heating mode, a water inlet and a water outlet are formed in the water heating pipe, hot water enters from one end of the water inlet and is discharged from one end of the water outlet, and the heating temperature of the foaming body can be controlled by controlling the temperature and the flow rate of the hot water in the water heating pipe.
And the upper end opening of the die cavity is hinged with a cover plate 2, and the upper end of the cover plate 2 is connected with a cover opening mechanism 3. The lid opening mechanism 3 includes a connecting rod 31 and a driving cylinder 32. The cylinder body of the driving cylinder 32 is fixed on the base 1; the end of the piston of the driving cylinder 32 is hinged to one end of a connecting rod 31, and the other end of the connecting rod 31 is fixed on the cover plate 2. Under the linkage effect of the cover opening mechanism 3, the cover plate 2 can be automatically opened and closed, so that labor is saved.
A forming die 5 is arranged in the die cavity, and a plurality of forming grooves 51 are formed in the upper surface of the forming die 5. When the earplug is produced, after the foaming body is injected into the molding groove 51, the cover plate 2 is pressed on the mold cavity, the cover plate 2 is overlapped with the upper surface of the molding die 5, and the molding groove 51 forms a relatively sealed molding cavity, so that the earplug with a specific shape is formed in the molding cavity by the foaming body.
Because the foaming body can generate certain gas in the thermal forming process, in order to improve the stability of the cover plate 2 when being covered, the forming groove 51 forms a relatively sealed forming cavity, the base 1 is provided with a locking mechanism 4, and the locking mechanism 4 comprises a buckle 41 and a driving mechanism 42. The driving mechanism 42 is positioned below the base; a locking groove 421 is formed at an end of the driving mechanism 42, and the driving mechanism 42 can freely move along the horizontal direction. The lower end of the buckle 41 is fixed in the buckle groove 421, the middle part of the buckle 41 is provided with a fixing point 411, the buckle 41 is hinged on the base through the fixing point 411, and the buckle 41 can do circular motion along the fixing point 411 under the action of the cylinder; a limiting protrusion 412 is arranged at the upper end of the buckle 41, and the limiting protrusion 412 is positioned at the inner side of the buckle 41. Preferably, the limit protrusion 412 is a triangle, a semicircle, or the like, and has a certain sliding buffer structure.
When the cover 2 moves to the upper end of the buckle 41 under the action of the cover opening mechanism 3, the cover 2 continues to move downwards, at this time, after the buckle 41 slightly rotates along the fixing point 411 under the action of the cover 2, the cover 2 is closed, and the protrusion at the upper end of the buckle 41 is buckled above the cover 2. In the locking process, when the cover plate 2 is fastened to the buckle 41, the lower end of the buckle 41 is in rigid contact with the buckle groove 421, so that the lower end of the buckle 41 is worn after long-term use, and in order to prolong the service life of the buckle 41 and enable the buckle 41 to reset, the buffer spring 422 is further arranged in the buckle groove 421.
As a further technical solution of the present invention, the driving mechanism 42 is connected to the central control system, after the thermoforming is finished, the central control system sends a signal to the driving mechanism 42, the driving mechanism 42 pulls the lower end of the buckle 41 backwards, the upper end of the buckle 41 is far away from the cover plate 2, at this time, the protrusion is separated from the cover plate 2, the central control system sends a signal to the uncovering mechanism 3, and the uncovering operation is completed under the action of the driving cylinder 32.
As a further technical scheme of the invention, the forming die 5 and the base 1 are arranged in a split mode, and the forming die 5 is detachably fixed in the die cavity. When the forming die 5 is replaced, a dismounting hole 1 is formed in the bottom of one side of the die cavity for facilitating taking. When the forming die 5 needs to be replaced, the forming die 5 can be taken out through the dismounting hole 1 after the cover plate 2 is only needed to be opened, and the convenience and the rapidness are realized.
In the production of the foamed earplug, the molding die 5 is placed in the cavity, and the molding groove 51 is filled with the foam. The cover plate 2 is covered at the upper port of the die cavity under the action of the locking mechanism 4, the temperature and the flow rate of hot water in the water heating pipe are adjusted, the heating time is set, and the foaming body completes foaming in the molding groove 51. Under the action of the central control system, the locking mechanism 4 is separated from the cover plate 2, the cover plate 2 is opened under the action of the driving air cylinder 32, at the moment, the forming die 5 is exposed in the air and naturally cooled, and then an operator directly takes out the forming die 5 from the die cavity and puts the forming die 5 into a new forming die 5.
When the cover plate 2 is covered on the upper port of the mold cavity, the driving cylinder 32 is in a horizontal state, and at the moment, the axis of the driving cylinder 32 is 90 degrees with the axis of the molding groove 51, and the acting force of the driving cylinder 32 on the cover plate 2 is 0. In order to avoid the gas formed when the foaming body foams in the molding groove 51 from jacking up the cover plate 2, the locking mechanism 4 is additionally arranged on the thermoforming device, when the cover plate 2 is closed, on one hand, the sealing performance of the molding groove 51 can be improved, on the other hand, the action time of the driving air cylinder 32 can be reduced, and the service life of the driving air cylinder 32 can be prolonged.
