Abstract
The utility model discloses a sealed translucent cover of display backplate advances glued structure with injection mould, including upper die benevolence and lower mould benevolence, be equipped with two die cavities between upper die benevolence and the lower mould benevolence, be equipped with between the die cavity into rubber tube and with advance the cushion chamber that rubber tube is connected, sealed translucent cover includes the lid of the first half and the portion of inserting of the latter half, the both sides slant downwardly extending that the cushion chamber is close to mutually with the die cavity has dive to water, the side direction that bottom below was connected with vertical setting in the die cavity advances gluey chamber, dive water and side direction advance gluey chamber and be linked together. The liquid glue enters the buffer cavity through the glue inlet pipeline and then enters the submarine gate, and due to the design of the large part and the small part of the submarine gate, the liquid glue can be quickly injected into the lateral glue inlet cavity, the liquid glue in the lateral glue inlet cavity enters the bottom of the cavity from bottom to top, so that the whole cavity is completely filled, the liquid glue cannot impact and advance in the arc-shaped surface on the cavity, the circulation cannot occur, and no serpentine exists on the arc-shaped surface of a product discharged from the die.
Description
Technical Field
The utility model relates to a sealed transparent lid of display backplate is with injection mould advances glued structure.
Background
At present, a transparent sealing cover is usually adopted for sealing a screw hole and a large plug jack, the transparent sealing cover has higher visual requirements on an arc surface of the outer surface of a cover body, and various lines and scratches cannot be formed on the screw hole and the large plug jack, but during injection molding, liquid entering a glue inlet pipeline in a general injection molding method shown in a figure 3 enters a buffer cavity and then directly enters an upper cover in the cavity from a sprue at the side edge, liquid glue can form circulation in the buffer cavity due to a large-area arc surface and a high flow rate, and after mold stripping and cooling, the arc surface of the transparent cover has more serpentine lines, so that the factory requirements of products are not met.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a sealed transparent lid of display backplate is with injection mold advances glued structure.
The utility model discloses technical scheme as follows: the utility model provides a sealed transparency of display backplate is with injection mould advances glued structure, includes upper die benevolence and lower die benevolence, be equipped with two die cavities between upper die benevolence and the lower die benevolence, be equipped with between the die cavity into glue pipe and with advance the cushion chamber that glue pipe is connected, sealed transparency is covered including the lid of first half and the portion of inserting of latter half, the both sides slant downwardly extending that cushion chamber and die cavity are close to mutually has the dive to water, the side direction that bottom below was connected with vertical setting in the die cavity advances gluey chamber, the dive water advances gluey chamber with the side direction and is linked together.
Specifically, the method comprises the following steps: the inner diameter of the submarine gate gradually decreases from top to bottom, and an acute angle formed by the extension line of the submarine gate and the horizontal line is 45-60 degrees.
The beneficial effects of the utility model reside in that: the liquid glue enters the buffer cavity through the glue inlet pipeline and then enters the submarine gate, and due to the design of the large part and the small part of the submarine gate, the liquid glue can be quickly injected into the lateral glue inlet cavity, the liquid glue in the lateral glue inlet cavity enters the bottom of the cavity from bottom to top, so that the whole cavity is completely filled, the liquid glue cannot impact and advance in the arc-shaped surface on the cavity, the circulation cannot occur, and no serpentine exists on the arc-shaped surface of a product discharged from the die.

Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, a glue inlet structure of an injection mold for a display back plate sealing transparent cover comprises an upper mold core 1 and a lower mold core 7, wherein two mold cavities 4 are arranged between the upper mold core 1 and the lower mold core 7, a glue inlet pipeline 2 and a buffer cavity 3 connected with the glue inlet pipeline 2 are arranged between the mold cavities 4, the sealing transparent cover comprises a cover body 8 of an upper half part and an inserting part 9 of a lower half part, two sides of the buffer cavity 4 close to the mold cavities 4 extend downwards in an inclined mode to form a down-gate 5, a vertically arranged lateral glue inlet cavity 6 is connected to the bottom of the mold cavity 4, and the down-gate 5 is communicated with the lateral glue inlet cavity 6.
In the utility model, the inside diameter of the submarine gate 5 is gradually reduced from top to bottom, and the acute angle formed by the extension line of the submarine gate 5 and the horizontal line is 45-60 degrees.
In the actual use process, the liquid glue enters the buffer cavity 3 from the glue inlet pipeline 2 and then enters the submarine gate 5, due to the design of the size of the upper part of the submarine gate 5, the liquid glue can be rapidly injected into the lateral glue inlet cavity 6, the liquid glue in the lateral glue inlet cavity 6 enters the bottom of the cavity from bottom to top and then completely fills the whole cavity, the liquid glue cannot impact and advance in the upper arc-shaped surface of the cavity, circulation cannot occur, and no serpentine exists on the upper arc-shaped surface of a product after mold stripping.
The drawings and the embodiments are only for illustrating the present invention, and any suitable changes or modifications made by those skilled in the art should not be considered as departing from the scope of the present invention.
