Detailed Description
The invention is further described below with reference to examples and figures:
example 1
As shown in fig. 1, the mold comprises an upper mold plate 1 and a glue injection cylinder 2, wherein the lower end of the upper mold plate 1 is seamlessly connected with a cylindrical glue injection plug 11, an inward concave glue groove 21 is formed in the upper end of the glue injection cylinder 2, and the glue groove 21 is also cylindrical and matched with the position, shape and size of the glue injection plug 11. The bottom of the glue injection cylinder 2 is provided with two through glue injection holes 22, and the glue injection holes 22 are communicated with the bottom of the glue groove 21, in this embodiment, the number of the glue injection holes 22 is two. In the long-term use process of the die, the rubber injection plug 11 and the rubber groove 21 are worn continuously, so that a gap is formed between the rubber injection plug 11 and the rubber groove 21, and the gap is larger and larger. The glue material leaks from the gap between the glue injecting plug 11 and the glue groove 21, so that the glue material in the glue groove 21 is reduced, the pressure in the glue groove 21 is reduced, and the product quality is seriously affected.
In order to prevent the glue from leaking from the gap between the glue injection plug 11 and the glue groove 21, a glue overflow preventing structure is arranged between the glue injection plug 11 and the glue groove 21. The glue overflow preventing structure in this embodiment is a thin layer of flexible material 31. The manufacturing of the molded product is as follows: firstly, hot-melt sizing material is injected into the sizing groove 21 through the sizing hole 22, after the sizing material is injected, the flexible material 31 is covered at the sizing groove 21, and the size of the flexible material 31 is larger than the diameter of the sizing groove 21, so that the sizing groove 21 can be completely covered. Then the rubber injection plug 11 is pressed down into the rubber groove 21, and the rubber material in the rubber groove 21 is extruded and shaped. At this time, the rubber filling plug 11 presses the flexible material 31 into the rubber groove 21, so that the flexible material 31 fills up the gap between the rubber filling plug 11 and the rubber groove 21, high internal pressure can be generated in the rubber groove 21, and the product quality is ensured to be stable.
Example two
As shown in fig. 2, the difference between the present embodiment and the first embodiment is that the side wall of the glue groove 21 is first provided with an annular groove 32, and the glue entering the glue groove 21 from the glue injection hole 22 fills the groove 32. After the grooves 32 are filled with the rubber, the upper template 1 is pressed down, so that the rubber at the grooves 32 on the side wall of the rubber groove 21 can generate radial pressure on the rubber injection plug 11, and the rubber forms an anti-overflow structure at the grooves 32 on the side wall of the rubber groove 21. The glue overflow preventing structure formed by the glue in the embodiment can prevent the glue in the glue groove 21 from leaking from the gap between the glue injection plug 11 and the glue groove 21, ensure that high internal pressure is generated in the glue groove 21, and ensure stable product quality.
Example III
As shown in fig. 3, the difference between the present embodiment and the first embodiment is that in the present embodiment, an annular groove 32 is formed on the side surface of the rubber injection plug 11, and in the process of pressing down the upper mold plate 1, the rubber material in the rubber groove 21 gradually fills the annular groove 32 of the rubber injection plug 11. After the annular groove 32 is filled, the upper die plate 1 is continuously pressed down, so that the rubber material in the groove 32 of the rubber filling plug 11 can generate radial pressure on the rubber groove 21, and the rubber material forms a rubber overflow preventing structure at the groove 32. The glue overflow preventing structure formed by the glue in the embodiment can prevent the leakage of the gap between the glue injecting plug 11 in the glue groove 21 and the glue groove 21, ensure the high internal pressure in the glue groove 21 and ensure the stable quality of the product.
It will be apparent that several improvements or modifications may be made without departing from the principles of the invention.
