The injection mold 10 includes a liquid outlet assembly 100, a first molding die 200, a second molding die 300, and a positioning ring 400. The liquid outlet assembly 100 is used for providing injection molding liquid, a through hole 340 is formed in the second molding die 300, the first molding die 200 is inserted into the second molding die 300 by penetrating through the through hole 340, and a gap is formed between the inner walls of the first molding die 200 and the second molding die 300 to form the mold cavity 500. The liquid outlet assembly 100 is communicated with the mold cavity 500, and the injection molding liquid is injected into the mold cavity 500 through the liquid outlet assembly 100 and is cooled and solidified, so that a molded product is obtained. The positioning ring 400 has a positioning hole 410 and a positioning groove 420 at the middle and the periphery thereof, wherein the positioning hole 410 penetrates through the positioning ring 400, and the positioning groove 420 is located on one side of the positioning ring 400 in the axial direction. The first molding die 200 passes through the positioning hole 410 and the through hole 340, and one end of the second molding die 300 is in insertion fit with the positioning groove 420, so that the first molding die 200 and the second molding die 300 are simultaneously fixed by the positioning ring 400 to fix the relative position between the first molding die 200 and the second molding die 300, thereby ensuring that no relative displacement occurs between the first molding die 200 and the second molding die 300 in the injection molding process, and further ensuring that the wall thickness of the finally obtained product is uniform.
The injection liquid may be a liquid plastic or a liquid silicone rubber, and after the injection liquid is cooled and solidified in the cavity 500, a product having the same shape as the cavity 500 may be formed.
Note that, in the present embodiment, the perpendicularity of the first molding die 200 and the second molding die 300 in the axial direction is within 0.01 mm.
Referring to fig. 3, the liquid outlet assembly 100 includes a liquid outlet pipe 110, a liquid inlet pipe 120 and a connecting block 130, wherein the connecting block 130 is connected to the liquid outlet pipe 110 and the liquid inlet pipe 120 respectively. The injection liquid enters from the liquid inlet pipe 120, flows into the liquid outlet pipe 110 through the connecting block 130, and is injected into the mold cavity 500 from the liquid outlet pipe 110.
It can be understood that the connecting block 130 has a channel formed therein for communicating the liquid inlet pipe 120 and the liquid outlet pipe 110, and the injection liquid flows into the liquid outlet pipe 110 in the channel after entering from the liquid inlet pipe 120.
Referring to fig. 4 and 5, the second molding die 300 includes an injection molding portion 310, a molding portion 320, and a positioning portion 330, and the injection molding portion 310 and the positioning portion 330 are located at two opposite sides of the molding portion 320. The through hole 340 penetrates the injection portion 310, the molding portion 320 and the positioning portion 330, and the first molding die 200 penetrates the through hole 340 and cooperates with the second molding die 300 to form the mold cavity 500. The liquid outlet assembly 100 injects the injection liquid into the mold cavity 500, and after the injection liquid is cooled and solidified, a product with the same shape as the mold cavity 500 is formed.
Specifically, the first molding die 200 passes through the through-hole 340, and a gap exists between the inside of the through-hole 340 and the inner wall of the second molding die 300 to form the mold cavity 500. More specifically, after the first molding die 200 passes through the through hole 340, one end of the first molding die is flush with the injection portion 310, and the other end of the first molding die passes through the positioning portion 330 and is exposed out of the through hole 340. The size of the through-hole 340 at the positioning portion 330 is adapted to the first molding die 200 so that the first molding die 200 contacts the inner wall of the second molding die 300 at the positioning portion 330 of the second molding die 300, thereby closing the gap between the first molding die 200 and the second molding die 300 at the positioning portion 330. As shown in fig. 5, the liquid outlet pipe 110 of the liquid outlet assembly 100 is located at the injection portion 310 side of the second molding die 300, and after flowing out from the liquid outlet pipe 110, the injection liquid flows into the through hole 340 through the injection portion 310, and flows to the positioning portion 330 through the molding portion 320 along the gap between the first molding die 200 and the second molding die 300. Since the first molding die 200 is in contact with the inner wall of the second molding die 300 at the positioning portion 330, the flow of the injection liquid is stopped when the injection liquid flows thereto, and after the injection liquid fills the gap between the first molding die 200 and the second molding die 300, that is, the mold cavity 500, and is cooled and solidified, a product having a shape in accordance with the mold cavity 500 is formed.
It should be noted that a sealing ring (not shown) is further disposed between the positioning portion 330 of the second molding die 300 and the first molding die 200, so as to further increase the sealing performance between the positioning portion 330 of the second molding die 300 and the first molding die 200, and prevent the injection liquid in the mold cavity 500 from flowing out from the positioning portion 330.
Further, the positioning groove 420 is an annular groove, which is concentric with the positioning hole 410, and the positioning groove 420 is set to be annular, so that the contact area of the second molding die 300 and the positioning groove 420 during the insertion and matching is larger than that of the positioning grooves 420 in other shapes, and the insertion and matching between the second molding die 300 and the positioning groove 420 is firmer.
Referring to fig. 6 to 8, after the first molding die 200 passes through the through hole 340 and the positioning hole 410, the positioning portion 330 of the second molding die 300 is clamped with the positioning ring 400 at the positioning groove 420 of the positioning ring 400, so that the relative position between the first molding die 200 and the second molding die 300 is fixed by the positioning ring 400. Then, in the process of injecting the injection liquid into the mold cavity 500 through the liquid outlet pipe 110 to produce a product, since the relative positions of the first molding die 200 and the second molding die 300 are fixed, the shape of the mold cavity 500 is also fixed, and further, the shape of the product obtained by cooling and solidifying the injection liquid is kept consistent with the shape of the mold cavity 500 actually designed, and the condition that the shape of the mold cavity 500 is changed due to the displacement of the first molding die 200 relative to the second molding die 300 in the injection process, so that the final molded product has uneven wall thickness, etc. is avoided.
It should be noted that the relative position between the first molding die 200 and the second molding die 300 includes the distance between the inner walls of the through holes of the first molding die 200 and the second molding die 300, and the included angle between the axial direction of the first molding die 200 and the axial direction of the second molding die 300.
Further, as shown in fig. 1, 7 and 8, a groove 210 is formed on one surface of the first molding die 200, and the groove 210 is located on one surface of the first molding die 200 close to the liquid outlet assembly 100. When the injection liquid flows out from the outlet pipe 110, the injection liquid enters the groove 210, and when the groove 210 is filled, the injection liquid overflows from the groove 210 and flows into the mold cavity 500. Like this, through setting up recess 210, can avoid moulding plastics liquid directly to fall on the plane when flowing out from drain pipe 110, take place to mould plastics the sputtering of liquid, cause the potential safety hazard.
In the present embodiment, both the first molding die 200 and the second molding die 300 are cylindrical, but in other embodiments, the first molding die 200 and the second molding die 300 may also be rhombic, as long as the first molding die 200 and the second molding die 300 can be matched to form the cavity 500.
Referring to fig. 9 and 10, the injection mold 10 further includes a cooling member 600, and the cooling member 600 is located inside the first molding die 200 and is communicated with an external water source for increasing a cooling speed when the injection liquid is cooled in the mold cavity 500.

One end of the cooling member 600 is communicated with an external water source so that water flows into the cooling member 600 and flows out from the other end, thereby cooling the first molding die 200. By cooling the first forming die 200, the temperature of the injection molding liquid in the die cavity 500 is reduced, and the solidification speed of the injection molding liquid is increased.
Further, one end of the cooling member 600, which is not communicated with a water source, extends along the axial direction of the second molding die 300, and spirally surrounds one surface of the second molding die 300, which is away from the first molding die 200, so that the contact area between the coolant and the first molding die 200 and the second molding die 300 is further increased, and the cooling effect is further improved.
