Technical Field
[0001] This utility model relates to the field of mixing cup body manufacturing technology, specifically to an injection mold for a mixing cup body. Background Technology
[0002] A blending cup consists of two small cylindrical cups of different sizes. Between the two cylindrical cups is a rotating plastic blade, resembling a propeller, with a protruding, nail-like spike on it. The whole assembly of these two parts is called a blending cup. The cup body is the main component of the blending cup, used to hold the ingredients or liquids to be blended. Its material, structure, and other design factors affect the performance and user experience of the blending cup.
[0003] Chinese patent CN206568459U discloses an injection mold for forming a mixing cup. The cavity side snap-fit uses a front mold core-pulling mechanism for demolding, the multiple snap-fits on the outer side of the core use a double slider core-pulling mechanism for demolding, the multiple snap-fits on the inner side of the core use a slanted ejector mechanism for demolding, and the complete ejection of the product uses a push plate ejection method. This successfully achieves the demolding of various local snap-fit features on the product, realizes automated injection molding production, and features a novel mold structure and excellent production results.
[0004] The above scheme uses two threaded hydraulic cylinders to drive the core inserts on both sides to demold the molded part, which is inefficient. Moreover, after demolding, a multi-point ejection method is used for ejection and unloading. Since the thickness of each part of the molded part is different, the point ejection method can easily affect the surface quality of the molded part.
[0005] Therefore, this utility model provides an injection mold for the body of a mixing cup to solve the above problems. Utility Model Content
[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides an injection mold for the body of a mixing cup, which solves the problem that using two threaded cylinders to drive the core inserts on both sides to demold the molded part is inefficient, and that after demolding, the multi-point ejection method is used for ejection and unloading, but since the thickness of each part of the molded part is different, the point ejection method can easily affect the surface quality of the molded part.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An injection mold for a mixing cup body includes an upper mold and a lower mold. The upper mold includes an upper template and an upper mold box. A pouring cap, two inclined rods, and two insert rods are installed on the upper mold box. A wedge-shaped rod is fixedly connected to each of the two insert rods.
[0008] The lower mold includes a lower template, a fixed mold box, a movable mold box, and a limiting component. An electric push rod is installed on the fixed mold box, and the telescopic end of the electric push rod is fixedly connected to the movable mold box. The limiting component releases the limiting of the fixed mold box and the movable mold box in the mold-opening state through a plug rod and a wedge rod. A core component is installed on the fixed mold box, and a through groove matching the core component is opened on the movable mold box. Two core inserts are slidably connected on the movable mold box. Both core inserts have inclined grooves, and the core inserts move closer to the core component by inserting an inclined plug rod into the inclined groove.
[0009] Preferably, the upper mold box has an installation cavity, and the pouring cover is installed in the installation cavity, and the installation cavity matches the state of the two core inserts after they are combined.
[0010] Preferably, a first guide pin is installed on the upper mold box, a first guide hole is opened on the bottom surface of the upper mold box, a second guide pin that matches the first guide hole is fixedly connected to the movable mold box, and a second guide hole that matches the first guide pin is opened on the movable mold box.
[0011] Preferably, the limiting component includes a sliding groove formed on the fixed mold box and the movable mold box, two sets of inserts and two linkage blocks. The inserts are embedded in the sliding groove, and the linkage blocks are slidably connected to the sliding groove through the two inserts. One end of the linkage block is fixedly connected to an I-beam, and the grooves on both sides of the I-beam are respectively engaged with the two inserts.
[0012] Preferably, the movable mold box has a slot, and the slot is connected to the sliding groove, and the linkage block has an extrusion groove that matches the wedge rod.
[0013] Preferably, the movable mold box has a movable groove, a guide block is fixedly connected in the movable groove, the core insert has a guide groove, and the core insert is slidably connected to the guide block through the guide groove.
[0014] The beneficial effects of this utility model are as follows: 1. Demolding is achieved by moving the entire mold box through an electric push rod. The mold box makes uniform contact with the molded part, and the force on each part is stable during demolding, avoiding defects such as deformation and scratches caused by excessive local force. At the same time, the cooperation between the inclined insert and the inclined groove of the core insert allows the core insert to move simultaneously during mold opening and closing, avoiding the time loss of step-by-step operation and significantly improving demolding and overall production efficiency.
[0015] 2. Through the precise cooperation of the first guide pin and the second guide hole, and the second guide pin and the first guide hole, high-precision alignment of the upper mold box and the moving mold box is achieved, reducing mold closing deviation from the source. The core insert is connected to the guide block and the guide groove through sliding connection, which improves the stability during the movement process, ensures the consistency of the forming cavity after mold closing, reduces the risk of product scrap due to mold misalignment, and ensures the stability of mass production.
[0016] 3. Through the cooperation of wedge rods, linkage blocks, extrusion grooves, and the snap-fit structure of I-beam blocks and inserts, a stable connection between the fixed mold box and the moving mold box is achieved when the mold is closed. When the mold is opened, the limit can be automatically released by pulling out the wedge rod, without the need for additional operation steps. This simplifies the mold opening and closing process, improves the convenience of operation, enhances the reliability of the overall mold structure, and reduces the probability of failure in the production process.

[0023] The following will refer to the attached reference. Figures 1 to 5 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.
[0024] An injection mold for a mixing cup body includes an upper mold and a lower mold. The upper mold includes an upper template 1 and an upper mold box 2. The upper template 1 and the upper mold box 2 are connected together by bolts. The upper mold box 2 is equipped with a pouring cap 7, two inclined rods 27 and two insert rods 9. Each of the two insert rods 9 is fixedly connected with a wedge rod 10. The wedge rod 10 is inclined, specifically with its upper end close to the central axis of the upper mold box 2 and its lower end away from the central axis of the upper mold box 2.
[0025] In this embodiment, the lower mold includes a lower template 3, a fixed mold box 4, a movable mold box 5, and a limiting component. The lower template 3 and the fixed mold box 4 are connected together by bolts. A first guide pin 11 is installed on the upper mold box 2, and a first guide hole 12 is opened on the bottom surface of the upper mold box 2. A second guide pin 13 that matches the first guide hole 12 is fixedly connected to the movable mold box 5, and a second guide hole 14 that matches the first guide pin 11 is opened on the movable mold box 5.
[0026] When the upper mold box 2 and the movable mold box 5 are closed, the second guide pin 13 will be inserted into the inside of the first guide hole 12, and the first guide pin 11 will be inserted into the inside of the second guide hole 14, so as to complete the alignment of the upper mold box 2 and the movable mold box 5 and avoid mold closing deviation.
[0027] An electric push rod 26 is installed on the fixed mold box 4, and the telescopic end of the electric push rod 26 is fixedly connected to the movable mold box 5. The limiting component releases the limiting of the fixed mold box 4 and the movable mold box 5 in the mold-opening state through the insert rod 9 and the wedge rod 10. The limiting component includes a sliding groove 21 opened on the fixed mold box 4 and the movable mold box 5, two sets of inserts 22 and two linkage blocks 23. The inserts 22 are embedded in the sliding groove 21, and the linkage blocks 23 are slidably connected to the sliding groove 21 through the two inserts 22. One end of the linkage block 23 is fixedly connected to an I-beam block 24, and the grooves on both sides of the I-beam block 24 are respectively engaged with the two inserts 22. A core part 28 is installed on the fixed mold box 4, and a through groove matching the core part 28 is opened on the movable mold box 5.
[0028] In the mold-closed state, when the I-beam 24 is inserted into the two inserts 22, the I-beam 24 will connect the fixed mold box 4 and the movable mold box 5 into a whole. In the mold-open state, the I-beam 24 slides out from the sliding groove 21, releasing the connection between the fixed mold box 4 and the movable mold box 5. The movable mold box 5 is driven to move upward by the telescopic end of the electric push rod 26, and the demolding of the molded part on the core part 28 can be completed with the help of the movable mold box 5.
[0029] The movable mold box 5 has a slot 20, which is connected to the sliding groove 21. The linkage block 23 has an extrusion groove 25 that matches the wedge rod 10. After the wedge rod 10 is inserted into the extrusion groove 25, the linkage block 23 will move toward the core part 28 in the sliding groove 21. When the wedge rod 10 is pulled out from the extrusion groove 25, the linkage block 23 will move away from the core part 28.
[0030] In this embodiment, two core inserts 16 are slidably connected to the movable mold box 5.

Both core inserts 16 have inclined grooves 17, and the core insert 16 moves closer to the core part 28 by inserting the inclined rod 27 into the inclined groove 17.
[0031] During mold closing, the angled insert 27 is inserted into the angled groove 17 to cause the core insert 16 to move closer to the core 28, and the two core inserts 16 form a molding cavity after mold closing. During mold opening, the angled insert 27 is pulled out from the angled groove 17, and the core insert 16 moves away from the core 28, thereby completing the mold opening.
[0032] The upper mold box 2 has an installation cavity 6, and the pouring cover 7 is installed in the installation cavity 6. The installation cavity 6 matches the state after the two core inserts 16 are combined. After the upper mold box 2 covers the movable mold box 5, the pouring cover 7 will abut against the structure after the two core inserts 16 are combined, and complete the entire molding cavity with the help of the core 28.
