[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A stepless flow channel filling and balancing molding die structure includes a primary flow channel regulating valve component for controlling the volume of the flow channel, a flow channel regulating valve stop pin for adjusting in conjunction with the primary flow channel regulating valve component, and a secondary flow channel regulating valve component for secondary control. The filling flow channel is installed on the die. The primary flow channel regulating valve component and the secondary flow channel regulating valve component are respectively installed at the intersection of multiple flow channels in the filling flow channel. The flow channel regulating valve stop pin is installed on the primary flow channel regulating valve component.

[0006] The bottom of the mold is provided with a forming mold, and the forming mold has a plurality of mold forming grooves formed on it. The upper end of the mold forming groove is provided with a flow channel bottom nozzle corresponding to the position of the filling flow channel.

[0007] Preferably, the filling channel includes several main channels and branch channels, and the primary channel regulating valve component is installed on the main channel of the molding die.

[0008] Preferably, the stop pin of the flow channel regulating valve is connected to the primary flow channel regulating valve component via a thread.

[0009] Preferably, the secondary flow channel regulating valve component is installed on one side of the primary flow channel regulating valve component and located at the branch channel position of the filling flow channel.

[0010] Preferably, the flow channel bottom nozzle is vertically arranged, and the mold forming groove is provided with 10 independent structures.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By using stepless flow channel balancing technology, the volume of adhesive in the flow channel is controlled by adjusting the primary flow channel regulating valve to achieve initial flow channel balance; then, the flow rate of the adhesive entering the product is further controlled by the secondary flow channel regulating valve to achieve overall product filling balance; the parts are simple in design, quick and effective in adjustment, and easy to use.

The filling flow channel 4 is installed on the die. The primary flow channel regulating valve part 1 and the secondary flow channel regulating valve part 3 are respectively installed at the intersection of multiple flow channels in the filling flow channel 4. The flow channel regulating valve stop pin 2 is installed on the primary flow channel regulating valve part 1.

[0023] A forming mold 5 is provided at the bottom of the mold, and a number of mold forming grooves 51 are formed on the forming mold 5. A flow channel bottom nozzle 41 is provided at the upper end of the mold forming groove 51 corresponding to the position of the filling flow channel 4.

[0024] In this embodiment, the filling channel 4 includes several main channels and branch channels, and the primary channel regulating valve component 1 is installed on the main channel of the molding die 5.

[0025] In this embodiment, the stop pin 2 of the flow channel regulating valve is connected to the first-stage flow channel regulating valve component 1 by means of a thread.

Figure 1The filling channel 4 and the bottom nozzle 41 correspond to 10 mold forming slots 51. During the filling process, the volume of glue in the flow channel is first adjusted by the primary flow channel regulating valve part 1 to balance the flow channel injection synchronization. After the adjustment is completed, the primary flow channel regulating valve part 1 is fixed by the stop pin 2 of the flow channel regulating valve (which essentially adjusts the lateral position of the primary flow channel regulating valve part 1, thereby adjusting the flow size of the flow channel). Then, the flow rate is adjusted by the filling channel 4 to achieve injection balance of 10 independent products.
