The die with the inclined rubber inlet structure comprises a rear die 1 and an inclined rubber 2 which is arranged on the rear die 1 and matched with the rear die 1 to form a forming cavity surface, wherein a rubber inlet 3 which penetrates through the forming surface of the inclined rubber 2 to feed rubber is formed in the rear die 1.

The embodiment provides a mold with an oblique-square glue feeding structure, which comprises a rear mold and an oblique square which is arranged on the rear mold and matched with the rear mold to form a molding cavity surface, wherein a glue feeding opening penetrating through a molding surface of the oblique square for feeding glue is formed in the rear mold. Through set up into jiao kou on the back mould for the molten plastic can fill uniformly in the die cavity at rhombus and back mould place, avoids the plastic to be difficult to the condition on the rhombus shaping face that flows, can make and obtain good injection moulding effect, reaches improvement production efficiency and practices thrift the cost.

Further, as a preferred embodiment of the present invention, but not limited thereto, a cavity 11 for accommodating the oblique direction 2 is disposed on the rear mold 1, an insertion guide post 12 for inserting and matching with the oblique direction 2 is disposed on the cavity 11, and the glue inlet 3 is disposed on the insertion guide post 12. The inclined square is arranged on the cavity and is in plug-in fit with the plug-in guide pillar, the matching mode is simple and reliable, and the inclined square can be fixed on the rear die to form a cavity surface in a common shape. The matching mode of splicing is adopted, so that the splicing guide post is close to the central position of the oblique direction, the glue inlet can conveniently feed glue at the central position close to the oblique direction, and the glue can be uniformly fed when the size of the oblique direction is larger. Meanwhile, the rear die is large in size and high in strength, and the cavity arranged on the rear die has little influence on the strength of the rear die. The cavity surface in this embodiment refers to the surface of the cavity.

Further, as a preferred embodiment of the present invention, but not limited thereto, the plug guide post 12 includes a forming top surface 121 for cooperating with the forming surface of the rhombus 2, and the glue inlet 3 is located on the forming top surface 121. After the inserting guide pillar is inserted and matched with the oblique direction, the top surface of the inserting guide pillar is positioned on the oblique direction forming surface, so that the top surface is defined as the forming top surface. When advancing gluey mouth and being located the shaping top surface, the plastic can follow and advance gluey mouthful outflow and directly reach the shaping top surface, and then flow until filling up the die cavity along the shaping face of below one side, can avoid like this to lead to the cooling to influence the mobility of plastic after contacting with other positions of mould.

Further, as a preferred embodiment of the present invention, but not limited thereto, the present invention further includes a B plate 4, the inclined portion 2 is provided with a forming platform 21 flush with the forming top surface 121, and the forming platform 21 and the forming top surface 121 are horizontally disposed with respect to the B plate 4. The forming platform is flush with the forming top surface, and plastic can flow to an oblique direction from the inserting guide pillar. And the forming platform and the forming top surface are horizontally arranged relative to the plate B, so that the influence of a complex structure of an oblique square or a rear die on the flowability of the plastic can be avoided, and the plastic always passes through the forming platform and the forming top surface, so that the situation that the plastic is gathered at a glue inlet to cause data stagnation can be avoided.

Further, as a preferred embodiment of the present invention, but not limited thereto, the present invention further includes a thimble sleeve 5 disposed inside the insertion guide pillar 12, and the forming top surface 121 is provided with a concave 1211 communicated with the glue inlet 3 and the thimble sleeve 5. The concave station can be used for filling the plastic in advance and is communicated with the thimble, which is beneficial to thickening the thickness of the concave station position of the product, and the plastic which just enters the concave station is uniformly filled on the concave station and then flows to the periphery, and the concave station can also serve as a cold material hole.

Further, as a preferred embodiment of the present invention, but not limited thereto, the forming top surface 121 is provided with a flow channel 6 communicating the glue inlet 3 and the recessed platform 1211, and the flow channel 6 extends toward the glue inlet 3 and the recessed platform 1211.

Further, as a preferred embodiment of the present invention, but not limited thereto, an insert 7 detachably connected to the insert guide post 12 is disposed on the rear mold 1, and a portion of the runner 6 extending to the outside of the glue inlet 3 is located on the insert 7. The extended part of the glue inlet part is positioned on the insert and used as a cold material hole for placing the front cold material. The mold insert can also be provided with a cavity for producing injection molding parts with complex shapes,

further, as a preferred embodiment of the present invention, but not limited thereto, the inserting guide post 12 extends from the side wall of the cavity 11 and gradually increases toward the direction of inserting the inclined direction 2 into the rear mold 1. In this embodiment, the plug-in guide pillar is narrow from top to bottom wide shape, can strengthen the intensity of plug-in guide pillar like this.

Further, as a preferred embodiment of the present solution, but not limited thereto, the plug guide post 12 becomes gradually wider from the direction away from the rear mold. The inserting guide pillar gradually becomes wider from the direction far away from the rear die, and is used for limiting the oblique direction not to transversely move with the rear die, so that the oblique direction and the rear die can only be longitudinally inserted. Make between back mould and the rhombus can closely cooperate, reduce the clearance to reduce and drape over one's shoulders the cutting edge of a knife or a sword, make the injection molding reach good shaping effect.

Further, as a preferred embodiment of the present invention, but not limited thereto, the glue inlets 3 are respectively provided at positions of the rear mold 1 corresponding to both end portions of the rhombus 2. When the rhombus is too long, in order to accelerate the glue feeding speed and improve the production efficiency, the glue feeding ports are arranged at the two ends of the rhombus, so that the risks of glue leakage and glue shortage can be reduced.

The working principle of the embodiment is as follows:

The foregoing is illustrative of embodiments provided in connection with the detailed description and is not intended to limit the disclosure to the particular forms set forth herein.
