Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically an injection mold for a stirring cup filter. Background Technology

[0002] The blending cup filter is a key component in blenders or juicers used to separate liquids from solid residues. Its design and materials directly affect the smoothness of the beverage and the ease of cleaning. Its main function is to filter out residues such as fruit pulp and soybean pulp to ensure a smooth taste. The cylindrical part of the blending cup filter is usually made using injection molding.

[0003] Chinese patent CN206568459U discloses an injection mold for molding a mixing cup. It designs different demolding mechanisms for different parts of the product. The cavity side fasteners are demolded using a front mold core-pulling mechanism, the multiple fasteners on the outer side of the core are demolded using a double slider core-pulling mechanism, the multiple fasteners on the inner side of the core are demolded using a slanted ejector mechanism, and the complete ejection of the product is achieved by ejecting the part through a push plate. This successfully demolds the various fastener features on the product and realizes automated injection molding production.

[0004] The above solution uses the movement of the left and right core inserts to release the limiting position of the molded part, and relies on the movement of the lower core insert to complete the unloading of the molded part. However, since the cross-section of the mixing cup filter screen cylinder is usually frustum-shaped or cylindrical, relying solely on the movement of the inserts is insufficient to achieve complete demolding of the molded part. Therefore, we provide a mixing cup filter screen injection mold to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the existing technology and provide an injection mold for a stirring cup filter.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a stirring cup filter injection mold, comprising an upper mold plate, an upper mold box, a lower mold plate, a pad block, and a lower mold box. The upper mold box has an upper mold cavity, in which an upper mold insert and an inclined block are installed. The lower mold box has a lower mold cavity, in which a lower mold insert and a ejector ring are installed, and the ejector ring is slidably connected to the lower mold insert. The lower mold box is provided with two side mold inserts, and the opening and closing of the two side mold inserts is completed by the upper mold box driving the inclined block to move.

[0007] The lower template is provided with an mounting plate and a blanking plate, and the mounting plate is installed on the blanking plate. A first push rod and a second push rod are installed on the blanking plate. The top end of the second push rod passes through the lower mold box and is installed on the ejector ring. A through hole is opened on the lower mold insert, and the top end of the first push rod passes through the lower mold box and is inserted into the through hole.

[0008] Furthermore, two fixing blocks are installed on the lower mold box, and guide grooves are provided on both side mold inserts, and the side mold inserts are slidably connected to the fixing blocks through the guide grooves.

[0009] Furthermore, guide rods are fixedly connected to both ends of the fixing block, and guide holes are provided on both side mold inserts, with the side mold inserts slidably connected to the guide rods through the guide holes.

[0010] Furthermore, the side mold insert has an angled slot, and the bottom end of the angled insert is slidably connected to the angled slot.

[0011] Furthermore, the unloading plate is provided with an installation groove, and the bottom end of the second push rod passes through the unloading plate and is bolted to install an installation block, which is located in the installation groove.

[0012] Furthermore, the two ends of the pad are fixedly connected to the lower template and the lower mold box, respectively. A guide rod is installed on the lower template, and the top end of the guide rod is installed on the lower mold box. The mounting plate and the material cutting plate are slidably connected to the guide rod. A spring is sleeved on the guide rod, and the spring is located above the material cutting plate.

[0013] Furthermore, L-shaped grooves are provided on both the ejector ring and the side mold insert.

[0014] (III) Beneficial Effects: Compared with existing technologies, this stirring cup filter injection mold has the following advantages: I. This utility model uses a material ejection ring and a side mold insert in combination. The side mold insert first moves laterally to achieve side separation. Then, the material ejection ring rises under the drive of the second ejector rod, pushing the molded part away from the lower mold insert. This forms a dual demolding mechanism of side separation and top ejection. For the common frustum or cylindrical structure of the mixing cup filter cylinder, this ensures that the molded part can completely detach from the mold, avoids residue or deformation, and improves the reliability of demolding.

[0015] Second, in this utility model, the side mold insert is slidably connected to the fixed block through the guide groove, and moves on the guide rod with the help of the guide hole, which effectively constrains the lateral movement trajectory of the side mold insert. The inclined combination of the inclined insert and the inclined slot allows the lifting motion of the upper mold box to be accurately converted into the opening and closing action of the side mold insert, reducing the offset or jamming during the movement process, ensuring the consistency of the mold in the repeated opening and closing process, and reducing the product defect rate caused by component misalignment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-5As shown, this utility model provides a technical solution: a stirring cup filter injection mold, including an upper mold plate 1, an upper mold box 2, a lower mold plate 6, a pad block 7, and a lower mold box 8. The upper mold box 2 has an upper mold cavity 3, in which an upper mold insert 4 and an inclined insert block 5 are installed. The lower mold box 8 has a lower mold cavity 10, in which a lower mold insert 11 and a ejector ring 12 are installed. The ejector ring 12 is slidably connected to the lower mold insert 11. The lower mold box 8 is provided with two side mold inserts 9, and the opening and closing of the two side mold inserts 9 is completed by the upper mold box 2 driving the inclined insert block 5 to move.

[0020] Both the ejector ring 12 and the side mold insert 9 are provided with L-shaped grooves 20. After the side mold insert 9 moves, it will abut against the ejector ring 12 through the L-shaped grooves 20, so that the side mold insert 9 and the ejector ring 12 form the protruding part of the cylinder.

[0021] Two side mold inserts 9 cover the lower mold insert 11 and the ejector ring 12, and the upper mold insert 4 covers the top of the cavity formed by the two side mold inserts 9, thereby forming a molded part. Injection channels are provided on the upper mold plate 1 and the upper mold insert 4, through which the injection liquid is transported to the molding cavity and formed into a molded part after cooling.

[0022] In this embodiment, two fixing blocks 21 are installed on the lower mold box 8, and guide grooves 23 are provided on both side mold inserts 9. The side mold inserts 9 are slidably connected to the fixing blocks 21 through the guide grooves 23.

[0023] When the side mold insert 9 moves laterally, it moves to the fixed block 21 through the guide groove 23, and the fixed block 21 slides in the guide groove 23 to limit the side mold insert 9.

[0024] Both ends of the fixed block 21 are fixedly connected to guide rods 22, and both side mold inserts 9 are provided with guide holes 24, and the side mold inserts 9 are slidably connected to the guide rods 22 through the guide holes 24.

[0025] When the side mold insert 9 moves laterally, the side mold insert 9 will slide on the guide rod 22 through the guide hole 24 to ensure the stability of the lateral movement of the side mold insert 9.

[0026] Specifically, the side mold insert 9 has an angled slot 25, and the bottom end of the angled insert 5 is slidably connected to the angled slot 25.

[0027] Both the inclined insert 5 and the inclined slot 25 are inclined designs. After the inclined insert 5 is inserted into the inclined slot 25, the side mold insert 9 moves synchronously by means of the cooperation between the inclined insert 5 and the inclined slot 25. When the inclined insert 5 moves downward, the two side mold inserts 9 will perform a mold closing movement. When the inclined insert 5 moves upward, the two side mold inserts 9 will perform a mold opening movement.

[0030] After injection molding, the upper mold plate 1 and the upper mold box 2 are moved upward and the upper mold insert 4 is pulled out. The two side mold inserts 9 move towards each other to complete the side extraction. Then, the mounting plate 13 is moved upward and the first ejector rod 16 is used to push the gating channel of the molded part. The second ejector rod 17 drives the ejector ring 12 to move upward and push the molded part away from the lower mold insert 11.

[0031] The two ends of the pad 7 are fixedly connected to the lower template 6 and the lower mold box 8, respectively. A guide rod is installed on the lower template 6, and the top of the guide rod is installed on the lower mold box 8. The mounting plate 13 and the blanking plate 14 are slidably connected to the guide rod. A spring 26 is sleeved on the guide rod, and the spring 26 is located above the blanking plate 14. The guide rod guides the movement of the mounting plate 13 and the blanking plate 14.
