The invention relates to the technical field of plastic molds, in particular to a carbon fiber plate glue inlet structure.

[ background of the invention ]

As shown in fig. 1, in the production, a plastic frame 602 combined with a carbon fiber plate 601 is molded on the carbon fiber plate 601 using a plastic mold, and the plastic frame 602 has an inner edge and an outer edge. The inner edge of the plastic frame 602 is located inside the edge of the carbon fiber plate 601, and the outer edge of the plastic frame 602 is located outside the edge of the carbon fiber plate 601.

When the plastic frame 602 is molded by a plastic mold, there are two glue feeding manners in the prior art, namely, glue feeding from the outside and glue feeding from the inside.

Referring to the outer glue feeding point 701 in fig. 1, the outer glue feeding point is located near the outer side of the cavity for molding the plastic frame 602, which has the following disadvantages: the gas trapped inside the outer side and the inner side cannot be removed after molding, resulting in poor appearance after molding. Therefore, the inner side glue feeding mode is generally adopted.

Referring to the inner side glue feeding point 702 in fig. 1, the glue feeding point is located near the inner side of the cavity for molding the plastic frame 602, during the molding process, the inner side is molded first and then the outer side is molded, and the gas in the cavity is extruded and exhausted from the outer side. This method has a disadvantage that the molten plastic is directly punched on the carbon fiber sheet 601, and the impact force of the plastic is large, so that the carbon fiber sheet 601 has poor appearance (having a blanking mark) after receiving the impact.

Therefore, there is a need for improvements in the prior art.

The invention provides a carbon fiber plate glue feeding structure, which comprises:

the device comprises an inclined pin 1 and a mould core 2, wherein a plurality of hot nozzle heads 3 are arranged on the mould core 2.

Referring to fig. 4, when the taper pin 1 abuts against the mold core 2, a flow passage 4 and a discharge port 5 are formed between the taper pin 1 and the mold core 2. The flow passage 4 includes a first cavity 401 and a second cavity 402 which are communicated with each other, the second cavity 402 is narrowed with respect to the first cavity 401, and the second cavity 402 is gradually narrowed from a communication position where it is communicated with the first cavity 401 to the discharge port 5.

Here, both the first cavity 401 and the second cavity 402 are elongated and have the same length direction, and one side of the first cavity 401 is communicated with one side of the second cavity 402. The nozzle tip 3 is communicated with the first cavity 401, and the plurality of nozzle tips 3 are distributed along the length direction of the first cavity 401. The discharge port 5 is communicated with the second cavity 402, the discharge port 5 is long, and the length direction of the discharge port 5 is consistent with that of the second cavity 402.

It should be noted that, for the convenience of understanding, the stub bar 8 is shown in the figure, and the stub bar 8 is also called runner residue and is formed after plastic is solidified in the runner 4, so that the shape of the stub bar 8 is consistent with the shape of the runner 4. Meanwhile, the mold core 2 shown in fig. 3 and 4 is a partial structure of the mold core 2.

Specifically, referring to fig. 4 and 6, the mold core 2 has a recess on a side facing the taper pin 1, and the taper pin 1 has a buffer surface 101 on a side facing the mold core 2.

The inner wall of the recess has a first wall 201 and a second wall 202, the first wall 201 and the second wall 202 are both long planes, the first wall 201 and the second wall 202 have two long sides, and one long side of the first wall 201 is connected with one long side of the second wall 202. The first wall 201 and the second wall 202 form an angle of 90 degrees.

The second wall surface 202 is disposed opposite to the buffer surface 101. The cushioning surface 101 includes a first portion 1011 and a second portion 1012, the second portion 1012 being recessed relative to the first portion 1011. In the first portion 1011, the position farther from the second portion 1012 is inclined in the direction of the second wall surface 202.

The first wall 201 is located between the second wall 202 and the second portion 1012, and the thermal nozzle 3 penetrates the first wall 201 to communicate with the recess.

Referring to fig. 4, when the taper pin 1 abuts against the mold core 2, the other long side of the first wall 201 abuts against the second portion 1012, the first wall 201, the second wall 202 and the buffer surface 101 define a flow channel 4, and a discharge hole 5 is formed between the other long side of the second wall 202 and the first portion 1011. It should be noted that, at this time, a space sandwiched between the first portion 1011 of the buffer surface 101 and the second wall surface 202 is the second cavity 402, and a space sandwiched between the second portion 1012 of the buffer surface 101 and the second wall surface 202 is the first cavity 401.

Referring to fig. 4 and 7, fig. 7 is a diagram illustrating a state of use of a carbon fiber plate glue-inlet structure according to the present invention. When the carbon fiber plate glue feeding structure is used for feeding glue, the position of the discharge port 5 is close to the inner edge of a cavity for molding a plastic frame 602, plastic is flushed into the flow channel 4 from the hot nozzle head 3, firstly enters the first cavity 401 and flushes onto the second part 1012 of the buffer surface 101 to buffer part of impact force, secondly, as the second cavity 402 is tightened relative to the first cavity 401, part of the plastic preferentially flows in the first cavity 401 along the length direction thereof to remove part of the impact force and then flows into the second cavity 402, and finally, after the plastic flows into the second cavity 402, as the second cavity 402 is gradually narrowed from the communication part of the second cavity 402 and the first cavity 401 to the discharge port 5, part of the plastic preferentially flows in the second cavity 402 along the length direction thereof to further remove part of the impact force and then flows into the cavity from the discharge port 5, at the moment, the impact force of the plastic is greatly reduced, no stamping is left on the side of the carbon fiber plate 601 facing away from the plastic frame 602.

During the molding process, the inner side is molded first and then the outer side is molded, and the gas in the cavity is extruded and exhausted from the outer side.

When the carbon fiber plate glue feeding structure is used for feeding glue, plastic firstly passes through the first cavity 401, then passes through the second cavity 402 and finally flows out of the discharge hole 5, so that the impact of the plastic on the carbon fiber plate 601 is reduced, and the stamping mark left on the carbon fiber plate 601 is avoided.

Specifically, referring to fig. 5, fig. 5 is an exploded view of a carbon fiber plate glue-feeding structure according to the present invention. In this embodiment, the tilt pin 1 includes a head part 102 and a diagonal member 103, and the cushion surface 101 is located on the head part 102.

The diagonal draw bar 103 is inclined with respect to the head part 102.

The angle pin 1 is divided into a head part 102 and a diagonal draw bar 103, the head part 102 and the diagonal draw bar 103 are respectively machined when the angle pin 1 is manufactured, so that raw materials for manufacturing the head part 102 and the diagonal draw bar 103 can be conveniently selected, and the cushion surface 101 matched with the die core 2 is required to be positioned on the head part 102, so that the machining precision of the head part 102 is required to be higher than that of the diagonal draw bar 103, and the mode of assembly after separate machining is adopted, so that the angle pin is more convenient to machine.

It should be noted that the present invention is not limited to the above embodiments, and any simple modification, equivalent change and modification made to the above embodiments by those skilled in the art based on the technical solution of the present invention fall within the protection scope of the present invention.
