[0031] Specifically, the plug 3 is an integrated plug, specifically including a nut 4, a screw 5 and a sealing portion 6 which are connected in sequence. A torsion hole 8 is opened at one end of the nut 4, and the torsion hole 8 is a screw slot or a wrench position. The screw slot is a cross slot, a cross cut slot, a Pozidriv slot, a plum blossom slot or a slot; the wrench position is a triangular slot, a hexagonal slot, a square slot, a hexagonal column slot or an H-shaped slot; the thread on the screw 5 is a triangular thread, a rectangular thread, a trapezoidal thread, a serrated thread, a pipe thread, a cylindrical thread or a conical thread; the sealing portion 6 has a taper, which can pass through The inclined surface of the side surface abuts against the inner wall of the sealed component for sealing. When the plug 3 and the diverter plate 9 cooperate for sealing, the plug 3 is threadedly matched with the plug mounting position of the diverter plate 9, and the sealing portion 6 passes through the diverter plate 9 and extends to the inside of the branch flow channel 10. At this time, the sealing portion 6 has a tapered inclined surface abutting against the inner wall of the plug mounting position, and when a torsional force is applied to the torsional hole 8, as the locking force of the plug 3 increases, the tapered inclined surface of the sealing portion 6 abuts against the inner wall of the plug mounting position for sealing, and the sealing effect is better.

[0032] During operation, force can be applied to the torsion hole 8 to drive the screw 5 to lock with the thread of the sealed part, and the tapered inclined surface of the sealing portion 6 can be abutted against the inner wall of the sealed part for sealing; the tapered inclined surface is fitted to the inner wall of the sealed part for sealing, and the number of accessories of the plug 3 is reduced to one piece, which effectively reduces the number of parts. During assembly, there is no need to consider the assembly size relationship between multiple parts; and the integrated plug uses a bevel to wedge with the sealed part, so the sealing effect is better.

[0033] Please refer to Figure 3 In one embodiment of the present invention, the taper value of the sealing portion 6 is α, wherein 0°<α≤5°.

[0034] Specifically, the taper value α of the sealing portion 6 is 0°<α≤5°, and it can be sealed by abutting the inner wall of the sealed component through the inclined surface of the side. When the plug 3 and the diverter plate 9 are sealed together, the plug 3 and the plug mounting position of the diverter plate 9 are threadedly matched, and the sealing portion 6 passes through the diverter plate 9 and extends to the inside of the branch flow channel 10. At this time, the sealing portion 6 has a tapered inclined surface that abuts the inner wall of the plug mounting position, and when a torsional force is applied to the torsional hole 8, as the locking force of the plug 3 increases greatly, the tapered inclined surface of the sealing portion 6 abuts the inner wall of the plug mounting position to seal, and the sealing effect is better.

[0035] In one embodiment of the present invention, the bevel angle tolerance of the sealing portion 6 is -0.01°.

[0036] Specifically, the bevel angle tolerance of the sealing portion 6 is -0.01°, so that the inclined surface of the sealing portion 6 of the plug 3 can fit more tightly with the inner wall of the plug installation position of the manifold, which can largely avoid the leakage of molten plastic.

[0037] Please refer to Figure 4 and Figure 5 One embodiment of the utility model further includes: a diverter plate 9, which has a plurality of branch channels 10 arranged therein, each of the branch channels 10 is connected to a corresponding plug installation position, and one end of the plug installation position close to the branch channel 10 is in shape with the sealing portion 6.

[0038] Specifically, a main channel 11 is opened in the middle of the diverter plate 9, and a plurality of branch channels 10 are opened inside the diverter plate. The branch channels 10 are all connected to the main channel 11, and the plurality of branch channels 10 are radially divergently distributed along the main channel 11, so that the molten plastic inside the channel can be evenly injected into each branch channel 10; each of the branch channels 10 is connected to a corresponding plug installation position, and the end of the plug installation position close to the branch channel 10 is in shape with the sealing portion 6, and the plug 3 is locked with the plug installation position to seal any branch channel 10, and the assembly is simple, with good sealing effect.

[0039] In one embodiment of the present invention, the plug installation position is threadedly matched with the plug 3 , and the plug 3 abuts against the plug installation position through the side of the sealing portion 6 to seal the branch flow channel 10 .

[0040] Specifically, the plug installation position is threadedly matched with the plug 3, and the plug 3 is abutted against the plug installation position through the side of the sealing portion 6, so that any branch flow channel 10 can be sealed, and the assembly is simple and has a good sealing effect.

[0041] In one embodiment of the present invention, the torsion hole 8 is a wrench position.

[0042] Specifically, the wrench position is a triangular groove, a hexagonal groove, a square groove, a hexagonal groove with a column or an H-shaped groove, which is more labor-saving and convenient when twisting the plug 3.

[0043] In one embodiment of the present invention, the diverter plate 9 and the plug 3 are made of the same material.

[0044] Specifically, in order to facilitate the subsequent processing of the branch flow channel inside the diverter plate 9 and the end 7 of the plug 3, the present application sets the diverter plate 9 and the plug 3 to be made of the same material, which can be more conveniently cut or polished, so that a smooth and dead-angle-free seal is formed between the plug 3 and the diverter plate 9.

[0045] In one embodiment of the present invention, the flow channel inside the diverter plate 9 is smoothly arranged.

[0046] Specifically, when molding plastic products with high transparency, in order to avoid the problem of glue hiding in dead corners inside the flow channel, the traditional method is to use the technical process of the plug 3 plus sandpaper polishing to achieve it, and the plug needs to be connected to the flow channel through a ball cutter after assembly, and the end of the plug needs to be polished after the plug 3 is plugged on the plug installation position of the diverter plate 9. Improper handling of this process will also cause deviations in the flow channel size, resulting in poor matching and glue hiding problems, causing the molten plastic in the flow channel to be contaminated and affecting the product quality; the structure of the diverter plate 9 and the plug 3 used in this application is to use the method of sealing the glue portion 6 with the inclined surface of the glue sealing portion 6 fitting the side wall of the plug installation position of the diverter plate 9. In terms of the method of polishing the flow channel, the past sandpaper manual polishing method is abandoned, and the fluid polishing process is used for polishing. The manual polishing is changed to a machine-controlled polishing method, which can further improve the overall dimensional consistency of the processing surface of the plug 3 and the flow channel, thereby avoiding the problem of glue hiding in the diverter plate and improving the quality of plastic parts.

[0047] Please refer to Figure 6 In one embodiment of the present utility model, the sealing portion 6 is provided with an arc-shaped inner corner at one end away from the nut 4 to form a molding surface 12 .

[0048] In one embodiment of the present invention, the molding surface 12 forms a smooth transition with the inner wall of the branch flow channel 10 .

[0049] Specifically, the present application processes the plug 3 using the same material as the diverter plate 9, and opens a wrench position on the nut 4 of the plug 3, which can be tightened with a wrench. A thread is set on the outer side of the screw 5, and the thread is a fine-pitch thread in the present application. The plug 3 is threadedly connected to the plug installation position of the diverter plate 9 through the thread in the middle, and at the same time, the locking force of the thread is used to make the tapered inclined side surface of the plug 3 fit more tightly with the inner wall of the plug installation position of the diverter plate 9, which can avoid glue seepage to a large extent. The angle tolerance of the inclined side surface of the plug 3 is -0.01 degrees during actual processing. After the plug 3 is assembled to the plug installation position of the diverter plate 9, the plug is formed with a ball cutter through the glue outlet. 3 is processed, and the diameter of the molding ball cutter used is equal to the caliber of the glue outlet. At this time, the ball cutter molding surface of the plug 3 is relatively rough; the flow channel of the diverter plate 9 and the additional processing surface of the plug 3, that is, the molding surface 12 need to be polished, and the fluid polishing equipment pressurizes the polishing fluid to 120 MPa, enters the flow channel of the diverter plate 9 through the fluid polishing inlet of the diverter plate 9, and then discharges the polishing fluid from the glue outlet of the diverter plate 9. This process is circulated for 30 minutes. The polishing fluid includes corundum and hydraulic oil. The polishing fluid will polish the flow channel and the molding surface 12 during its flow in the flow channel, which can form a smooth transition between the flow channel of the diverter plate 9 and the molding surface 12 of the plug 3, and the use effect is better.

[0050] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
