a remote controller key area glue feeding mechanism comprises an upper base plate, a water gap plate, an upper die core and a sprue bush; a groove is formed in one side, close to the water gap plate, of the upper mold core, an area glue inlet groove is formed in the bottom of the groove, and a plurality of flow channels communicated with a forming groove in the other side of the upper mold core are formed in the area glue inlet groove; the filling block is arranged in the groove and connected to the water gap plate through screws, an area glue inlet cavity is formed between the filling block and the area glue inlet groove, and the sprue bush sequentially penetrates through the upper padding plate, the water gap plate and the filling block and is communicated with the area glue inlet cavity.

Furthermore, one side of the upper backing plate, which is close to the water gap plate, is connected with a connecting plate through another screw, one end of each waste pulling rod is connected onto the connecting plate, and the other end of each waste pulling rod sequentially penetrates through the water gap plate and the filling block to be positioned in the area glue inlet cavity; the waste pulling rods are arranged corresponding to the runners.

Furthermore, the runner is close to recess one end and is equipped with the counter bore, draw useless pole to be close to regional gluey chamber one end of advancing and be connected with the back-off, the back-off is located the counter bore.

Furthermore, the side surface of the groove is inclined inwards, the side surface of the filling block is inclined inwards, and the section of the groove is matched with the section of the filling block.

The utility model has the advantages that: the utility model adopts the region to feed glue, reduces the length and the number of the flow channels, and avoids the flow channel interference condition and the condition of incomplete cavity filling; adopt the mouth of a river board to connect and draw useless pole, be convenient for pull out the remaining waste material in the runner after moulding plastics, be convenient for clear up the waste material.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 5, a remote controller key area glue feeding mechanism comprises an upper backing plate 1, a nozzle plate 2, an upper die plate 3, an upper die core 4 and a sprue bush 7; a groove 41 is formed in one side, close to the water gap plate 2, of the upper mold core 4, an area glue inlet groove 42 is formed in the bottom of the groove 41, and a plurality of flow channels 43 communicated with a forming groove in the other side of the upper mold core 4 are formed in the area glue inlet groove 42; the filling block 5 is arranged in the groove 41, the filling block 5 is connected to the water gap plate 2 through a screw, an area glue inlet cavity 6 is formed between the filling block 5 and the area glue inlet groove 42, and the sprue bush 7 sequentially penetrates through the upper padding plate 1, the water gap plate 2 and the filling block 5 to be communicated with the area glue inlet cavity 6.
