[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a base 1 and a shaping block 2. The shaping block 2 is arranged on the base 1, and the shaping block 2 is used to be inserted in the mold.

[0033] A shaping surface 21 is arranged on the inner end surface of the shaping block 2, and the shaping surface 21 can reach into the mold cavity. If there is an injection molded product in the mold cavity, the shaping surface 21 can abut against the molded product. The outer end surface of the shaping block 2 is arranged on the base 1.

[0034] The shaping block 2 is provided with a temperature control hole 22 for the circulation of heat exchange medium. The heat exchange medium includes coolant for cooling or high-temperature hot oil for heating. Steam heating can also be used. The extension direction of the temperature control hole 22 is aligned with the shaping surface 21. The heat exchange medium flowing in the temperature control hole 22 causes the temperature of the shaping surface 21 to change, thereby reducing or increasing the temperature of the area where the shaping surface 21 is located.

[0035] A temperature control tube 10 for the circulation of heat exchange medium is provided on the base 1. The temperature control tube 10 extends into the temperature control hole 22. The outlet end of the temperature control tube 10 is aligned with the shaping surface 21. There is a gap between the outlet end of the temperature control tube 10 and the shaping surface 21. The heat exchange medium first changes the temperature of the shaping surface 21. Because there is a gap between the temperature control tube 10 and the wall where the temperature control hole 22 is located, the heat exchange medium first cools the shaping surface 21 at the bottom of the temperature control hole 22, and then the heat exchange medium rises along the wall.

[0036] The base 1 is provided with a liquid inlet 11 and a liquid outlet 12. The liquid inlet 11 is connected to the temperature control tube 10, and the liquid outlet 12 is connected to the temperature control hole 22. The heat exchange medium enters the temperature control tube 10 from the liquid inlet 11, and then the heat exchange medium comes out of the temperature control tube 10 and enters the temperature control hole 22. As the heat exchange medium increases, the heat exchange medium flows out from the liquid outlet 12, thereby lowering or raising the local temperature in the mold.

[0037] A sealing groove 17 is provided on the base 1, and a sealing ring 23 is provided on the outer end surface of the shaping block 2 to isolate the heat exchange medium. The sealing ring 23 is sleeved in the sealing groove 17, so that the heat exchange medium is prevented from overflowing between the shaping block 2 and the base 1.

[0038] The liquid inlet 11 is connected to a first adapter 111, which is used to connect a heat exchange medium. The first adapter 111 is connected to the heat exchange medium through a pipeline. The liquid outlet 12 is connected to a second adapter 112, which is used to recover the heat exchange medium. The second adapter 112 recovers the heat exchange medium through a pipeline.

[0039] The first adapter 111 is provided with a first groove 110 for fixing, and the second adapter 112 is provided with a second groove 120 for fixing. The first groove 110 and the second groove 120 are used for external accessories so that the first adapter 111 and the second adapter 112 can be fixed.

[0040] The base 1 is provided with a fixing groove 15 for connection. The fixing groove 15 and the temperature control tube 10 are respectively located on both sides of the base 1. The fixing groove 15 is used to fix the driving end of the cylinder (not shown in the figure).

[0041] The fixing groove 15 is set through the surface of the base 1, and the first limiting strip 151 and the second limiting strip 152 are symmetrically set on both sides of the opening of the fixing groove 15. The first limiting strip 151 is set at a distance from the bottom wall of the fixing groove 15, and the second limiting strip 152 is set at a distance from the bottom wall of the fixing groove 15. In this way, the driving end of the cylinder is limited by the first limiting strip 151 and the second limiting strip 152, and the driving end of the cylinder is limited in the fixing groove 15 and will not fall off.

[0042] A positioning groove 16 is provided on the base 1 . The positioning groove 16 is located on the first limiting strip 151 . The positioning groove 16 cooperates with the driving end of the cylinder to be clamped in the fixing groove 15 .

[0043] The base 1 is provided with a first fixing hole 13 and a second fixing hole 14 at intervals. The first fixing hole 13 and the second fixing hole 14 are both located on the bottom wall of the fixing groove 15 . The first fixing hole 13 and the second fixing hole 14 are used to fix the base 1 in cooperation with other accessories.

[0044] A first bottom surface 121 and a second bottom surface 122 are respectively provided on both sides of the fixed groove 15, and a first inclined surface 113 and a second inclined surface 114 are also respectively provided on both sides of the fixed groove 15. The first inclined surface 113 is connected to the first bottom surface 121 and forms an angle, and the second inclined surface 114 is connected to the second bottom surface 122 and forms an angle. The first inclined surface 113 and the second inclined surface 114 are used to cooperate with the mold to make the shaping block 2 more stably fixed in the mold.

[0045] A third inclined surface 153 is also provided in the extension direction of the bottom wall of the fixing groove 15. The third inclined surface 153 is connected to the bottom wall of the fixing groove 15 and forms an angle. The third inclined surface 153 is located between the first inclined surface 113 and the second inclined surface 114. The third inclined surface 153 also makes the shaping block 2 more stably fixed in the mold.

[0046] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
