[0006] The front mold is arranged on the rear mold, and the front mold includes a frame plate, and the front mold core is fixedly embedded on the front side of the frame plate. A glue inlet is opened on the frame plate, and a glue inlet channel part is arranged inside the glue inlet. An extended glue inlet channel is opened on the front mold core directly below the glue inlet, and the diameter of the extended glue inlet channel is smaller than the glue inlet channel part and is connected with the glue inlet channel part.
[0007] In a specific embodiment, the glue inlet channel portion includes a glue inlet flow channel, which is located inside the glue inlet. A heat flow protection sleeve is also provided inside the glue inlet, and the heat flow protection sleeve is located outside the glue inlet flow channel.
[0008] In a specific embodiment, the top of the glue inlet flow channel is also connected to a glue inlet sleeve, the glue inlet sleeve is provided with a glue inlet port, and the glue inlet port is communicated with the glue inlet flow channel.
[0009] In a specific embodiment, a mold groove is provided on the rear mold, and the extended glue inlet channel is connected to the mold groove.
[0010] In a specific embodiment, the rear mold includes a base and a mold plate, the mold plate is arranged on the base, and the mold groove is arranged on the mold plate.
[0011] In a specific embodiment, a resilient member is provided between the base and the module plate.
[0012] In a specific embodiment, equal-height bolts are provided between the base and the module plate.
[0013] On the other hand, the present application also provides a car dashboard mold, and
[0014] The above-mentioned glue inlet channel and mold product.
[0015] The mold product is arranged on the rear mold.
[0016] Beneficial effect: By setting an extended glue feeding channel on the back of the front mold core, the diameter of which is smaller than the conventional glue feeding hot runner, the main flow channel of the front mold core can be directly extended to the parting surface, so that when the space at the glue feeding position of the mold is small, it is still convenient to feed the glue into the mold, and the glue feeding channel of the mold can be set normally.

[0024] See also Figure 1-4 The present application provides a glue inlet channel, including a front mold 1 and a rear mold 2.
[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The front mold 1 is arranged on the rear mold 2. The front mold 1 includes a frame plate 11. The front mold core 12 is fixedly embedded on the front of the frame plate 11. A glue inlet is provided on the frame plate 11. A glue inlet channel is provided inside the glue inlet. The front mold core 12 is located directly below the glue inlet and is provided with an extended glue inlet channel 8. The diameter of the extended glue inlet channel 8 is smaller than the glue inlet channel and is connected to the glue inlet channel. When the mold is injected, the front mold 1 is clamped on the rear mold 2, and then the glue is injected through the glue inlet on the frame plate 11. Then the hot glue flows into the extended glue inlet channel 8 through the glue inlet channel, and then enters the mold groove 3 for injection. The extended extended glue inlet channel 8 is provided on the back of the front mold core 12 to inject glue, so that its diameter is smaller than the conventional glue inlet hot runner, so that the main flow channel directly cut on the front mold core 12 extends to the parting surface, so that when the space at the mold injection position is small, the mold injection is still convenient, and the mold injection channel can be normally set.
