Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a mold for the base shell of a mixing cup. Background Technology

[0002] A blending cup is a functional container composed of two cylinders of different sizes. Its core structure includes the cup body and the blending component. It achieves liquid blending by manually or mechanically driving the built-in propeller-shaped rotating parts (such as plastic discs, blades, etc.), effectively solving the problem of beverage particle sedimentation. Mechanically driven blending cups require the base to be placed on the drive unit. However, the base, which is placed by direct insertion, is prone to tipping over due to external force. Therefore, the factory designs a groove on the inner wall of the blending cup base shell to improve the stability of the base on the drive unit by using a snap-fit ​​method.

[0003] In the prior art, Chinese patent CN212860230U discloses an injection mold for processing the shell of a mixer. It uses locking core-pulling blocks to assist in the forming of the locking part. Two locking core-pulling blocks are driven by corresponding second driving blocks, and the remaining locking core-pulling block and the side hole core-pulling block are driven by the first driving block. This optimizes the number of driving components and greatly reduces the mold cost.

[0004] Although the above solution uses multiple locking core-pulling blocks to assist in the forming of the locking part to complete the final product forming, the produced molded part has a protruding mounting part, which has poor stability when placed on a flat surface. Moreover, by using multiple locking core-pulling blocks to move in the same direction, the groove on the inner wall of the product will limit the removal of the locking core-pulling blocks, making it inconvenient to unload the molded part.

[0005] Therefore, this utility model provides a mold for the base shell 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 a mold for the base shell of a mixing cup, which solves the problems of the produced molded parts having a protruding mounting part, resulting in poor stability when placed on a flat surface, and the use of multiple locking core-pulling blocks moving in the same direction, where the grooves on the inner wall of the product limit the removal of the locking core-pulling blocks, making it inconvenient to unload the molded parts.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mold for a base shell of a mixing cup, comprising: The upper template is equipped with a first inclined rod, a second inclined rod, and a second molded insert. The second molded insert has storage grooves on both sides.

[0008] An upper mold box is provided, on which a fourth molding insert is slidably connected. The upper part of the fourth molding insert has a second inclined groove, and a second inclined rod matches the second inclined groove. A hole molding rod is fixedly connected to the fourth molding insert. A first molding insert is provided inside the upper mold box. The first molding insert has a receiving hole that matches the hole molding rod. Two third molding inserts are slidably connected to the first molding insert. Both third molding inserts have a first inclined groove, and the first inclined groove matches the first inclined rod. An insert block is fixedly connected to the third molding insert. A protruding insert is fixedly connected to the insert block. The insert block is inserted into the receiving groove by inserting the first inclined rod into the first inclined groove, and the protruding insert forms a protrusion outside the second molding insert.

[0009] The lower mold box is equipped with a fifth molding insert.

[0010] The lower mold frame is equipped with a feeding assembly for ejecting material.

[0011] Preferably, the component also includes a finished part, the top of which is provided with a mounting groove, the inner wall of which is provided with a limiting groove, and the outer wall of which is provided with a through hole that matches the hole forming rod.

[0012] Preferably, the protrusion formed by the protruding insert and the second molded insert matches the cavity formed by the mounting groove and the limiting groove, and the finished part matches the cavity formed by the first molded insert and the fifth molded insert.

[0013] Preferably, an electric push rod is installed on the lower mold box, and the telescopic end of the electric push rod abuts against the upper mold box.

[0014] Preferably, a guide rod is installed on the lower mold box, and both the upper mold box and the upper template are slidably connected to the guide rod.

[0015] Preferably, the feeding assembly includes a top plate slidably connected to the lower mold frame, a top rod is installed on the top plate, and both the lower mold box and the fifth molding insert are provided with top holes, with the top end of the top rod located inside the top hole.

[0016] The beneficial effects of this utility model are as follows: 1. By adopting a drive structure that combines multiple sets of inclined rods and inclined slots, the orderly movement of the molding inserts is achieved. When the mold opens, the first inclined rod is pulled out from the first inclined slot, which drives the protruding insert on the third molding insert to be stored in the storage slot of the second molding insert. The second inclined rod is pulled out from the second inclined slot, which allows the hole forming rod on the fourth molding insert to be stored in the storage hole of the first molding insert. This effectively avoids the inner wall groove of the finished part from limiting the core-pulling component. With the help of the ejector assembly of the lower mold frame, demolding and material unloading can be completed smoothly, reducing material unloading obstacles and improving production efficiency.

[0017] 2. Through the precise cooperation of the first, second, third, fourth, and fifth molding inserts, the outer wall, top structure, protruding parts, through holes, and inner wall of the finished part are formed respectively. The gaps between each component are controllable, ensuring uniform wall thickness and shape accuracy of the finished part. The use of inclined rods to drive the inserts simplifies the design of the driving components, eliminating the need for multiple locking core-pulling blocks that move in the same direction. This reduces the complexity of the mold structure while ensuring the molding effect, and helps control production costs. Attached Figure Description

[0024] The following will refer to the attached reference. Figures 1 to 5The 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.

[0025] A mold for the base shell of a mixing cup includes an upper template 1, a finished part 2, an upper mold box 7, a lower mold box 8, and a lower mold frame 9.

[0026] The upper template 1 is equipped with a first inclined rod 15, a second inclined rod 18, and a second molding insert 13. The two sides of the second molding insert 13 are provided with a storage groove 25. The upper template 1 is provided with an injection channel. The two sections of the injection channel are located on the upper template 1 and the second molding insert 13, respectively, and the two sections are connected. The injection liquid is injected into the molding cavity through the injection section on the second molding insert 13 for molding.

[0027] A fourth molding insert 19 is slidably connected to the upper mold box 7. The upper part of the fourth molding insert 19 has a second inclined groove 20, and the second inclined rod 18 matches the second inclined groove 20. The upper mold box 7 is designed with a hole that communicates with the second inclined groove 20, so that the second inclined rod 18 can be inserted into the second inclined groove 20 and the fourth molding insert 19 can move toward the molding cavity. A hole molding rod 21 is fixedly connected to the fourth molding insert 19. A first molding insert 11 is provided in the upper mold box 7. The first molding insert 11 has a receiving hole 12 that matches the hole molding rod 21. When the fourth molding insert 19 moves toward the molding cavity, the hole molding rod 21 will be inserted into the receiving hole 12 and move within the receiving hole 12.

[0028] Two third molded inserts 14 are slidably connected to the first molded insert 11. Each of the two third molded inserts 14 has a first inclined groove 16, and the first inclined groove 16 matches the first inclined insertion rod 15. An insertion block 24 is fixedly connected to the third molded insert 14, and a protruding insert 17 is fixedly connected to the insertion block 24. The insertion block 24 is inserted into the receiving groove 25 by inserting the first inclined insertion rod 15 into the first inclined groove 16, and the protruding insert 17 forms a protrusion on the outside of the second molded insert 13.

[0029] When the first inclined insert 15 is inserted into the first inclined groove 16 on the upper template 1, the third molding insert 14 will move the insert block 24 toward the upper mold box 7, and the protruding insert 17 on the third molding insert 14 will protrude on the second molding insert 13 to form a protrusion. When the first inclined insert 15 is pulled out from the first inclined groove 16, the third molding insert 14 will move toward the second molding insert 13, and the protruding insert 17 will be stored in the storage groove 25 for easy unloading.

[0030] A fifth molding insert 22 is installed on the lower mold box 8, and the inner wall of the finished part 2 is formed by the fifth molding insert 22.

[0031] The top of the finished part 2 is provided with an installation groove 3, the inner wall of the installation groove 3 is provided with a limiting groove 4, and the outer wall of the finished part 2 is provided with a through hole 5 that matches the hole forming rod 21.

[0032] The protrusion formed by the protruding insert 17 and the second molding insert 13 matches the cavity formed by the mounting groove 3 and the limiting groove 4. Thus, the protruding insert 17 and the second molding insert 13 form the mounting groove 3 and the limiting groove 4 during the molding of the finished part 2. The finished part 2 matches the cavity formed by the first molding insert 11 and the fifth molding insert 22. The wall thickness of the finished part 2 is related to the gap between the first molding insert 11 and the fifth molding insert 22. Furthermore, the first molding insert 11 forms the outer wall shape of the finished part 2, and the fifth molding insert 22 forms the inner wall shape of the finished part 2. An electric push rod 6 is installed on the lower mold box 8. The telescopic end of the electric push rod 6 abuts against the upper mold box 7. The telescopic end of the electric push rod 6 extends to assist in opening the upper mold box 7.

[0033] A guide rod is installed on the lower mold box 8, and the upper mold box 7 and the upper template 1 are slidably connected to the guide rod to guide the upper template 1 and the upper mold box 7 when they are closed, so as to avoid deviation.

[0034] The lower mold frame 9 is provided with a material ejection assembly, which includes a material ejection plate 10 slidably connected to the lower mold frame 9. A material ejection rod 23 is installed on the material ejection plate 10. Material ejection holes are provided on the lower mold box 8 and the fifth molding insert 22, and the top end of the material ejection rod 23 is located in the material ejection hole.

[0035] During the unloading process, the upper template 1 and the upper mold box 7 are moved upward in sequence. After the upper template 1 moves upward, the first inclined insert 15 is pulled out from the first inclined groove 16, which can store the protruding insert 17 into the storage groove 25, so as to avoid the protruding insert 17 on the third molding insert 14 from obstructing the demolding of the finished part 2. At this time, the second molding insert 13 is removed from the top of the finished part 2, releasing the top limit of the finished part 2. Moreover, the second inclined insert 18 is pulled out from the second inclined groove 20, and the upper hole forming rod 21 of the fourth molding insert 19 is stored in the inside of the storage hole 12. When the upper mold box 7 moves upward again, the upper mold box 7 will drive the first molding insert 11 to move upward, thereby releasing the side limit of the finished part 2. Finally, the ejector rod 23 on the ejector plate 10 moves upward, and the ejector rod 23 completes the ejection of the finished part 2 on the fifth molding insert 22, thereby facilitating the demolding and removal of the finished part 2.
