Description

Technical Field

[0001] The utility model relates to the field of plastic product forming molds, in particular to a storage basket forming mold. Background Art

[0002] Existing storage basket forming molds are generally composed of two or more sets of mold cores, and the mold cores are generally installed between the upper module and the lower module. The mold core is mainly composed of a core seat, an upper core block and side core blocks on four sides. During injection molding, the core seat, the upper core block and the side core blocks on four sides form an injection space to allow the molten plastic to flow in. When the injection molding is completed, the lower module drives the core seat to separate, allowing the robotic arm or workers to take out the injection molded product. At present, the four side core blocks of the mold core are all moved and separated in one horizontal direction, so that a sufficiently long moving distance is required between the two mold cores, which increases the size of the entire storage basket forming mold and increases the volume and weight of the mold. Such a mold requires a higher-powered injection molding machine to be used for injection molding, which is cumbersome to operate and has high energy consumption. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a storage basket forming mold with a relatively small volume and light weight.

[0004] The utility model achieves the above-mentioned purpose in the following way:

[0005] A storage basket forming mold includes an upper module, a middle module, a lower module and a mold core. The mold core is installed between the middle module and the lower module. The mold core is mainly composed of a mold core seat, an upper core block and side core blocks on four sides. The side core blocks on the four sides can be slidably installed on the guide tube of the middle module. The guide tube is arranged tilted from bottom to top. The side core blocks and the middle module are connected to a power actuator that drives the side core blocks to slide along the guide tube.

[0006] Wherein, the power actuator is an oil cylinder or an air cylinder, the main body of which is fixed on the side core block, and the movable end is connected to the middle module.

[0007] Wherein, a T-shaped joint is fixed to the movable end of the power actuator, and the cylinders on both sides of the T-shaped joint are embedded in a groove of the U-shaped piece, and the U-shaped piece is fixedly connected to the middle module.

[0008] The bottom of the core seat is connected to the lower module, and the lower module is connected to the middle module and the upper module through a sleeve and a slide column.

[0009] Among them, the power actuator is installed on the outside of the side core block, and each mold core has two, which are arranged opposite to each other. The side core block equipped with the power actuator is connected to the adjacent side core blocks on both sides by a connecting arm. The connecting arm is fixed on one of the side core blocks and is movably connected to the other side core block.

[0010] The corners of the side core blocks are provided with grooves No. 2, and the connecting arms are provided with convex strips, which are sunk into the grooves No. 2 to realize the connection between the connecting arms and the side core blocks.

[0011] Each side core block is slidably connected to two guide tubes, which are fixed on the middle module.

[0012] The beneficial effects of the present invention are as follows: since the side core blocks on all sides are mounted on the conduit, when the power actuator is activated, the side core blocks will move along the conduit. When the side core blocks move upward, the side core blocks on all sides will be close together, waiting for the injection molding operation; when the side core blocks move downward, the side core blocks on all sides will separate from each other, making it easier to remove the injection molded parts. In addition, since the conduit is tilted from bottom to top, the power actuator can also be tilted, thereby saving the need to increase the distance between the two mold cores when setting it horizontally, effectively reducing the horizontal size of the mold. The mold thus produced is smaller in size and smaller in volume, avoiding the need for high-power injection molding machines for injection molding, facilitating operation, and saving energy consumption.

[0017] Reference Figures 1 to 3A storage basket forming mold includes an upper module 1, a middle module 2, a lower module 3 and a mold core 4. The mold core 4 is installed between the middle module 2 and the lower module 3. The mold core 4 is mainly composed of a mold core seat 41, an upper core block 42 and four side core blocks 43. The four side core blocks 43 are slidably installed on the guide tube 5 of the middle module 2. The guide tube 5 is tilted from bottom to top. The side core blocks 43 and the middle module 2 are connected to a power actuator 6 that drives the side core blocks 43 to slide along the guide tube 5. Since the side core blocks 43 on all sides are installed on the guide tube 5, when the power actuator 6 is activated, the side core blocks 43 will move along the guide tube 5. When the side core blocks 43 move upward, the side core blocks 43 on all sides will be close together, waiting for the injection molding operation; when the side core blocks 43 move downward, the side core blocks 43 on all sides will separate from each other, making it convenient to remove the injection molded parts. In addition, since the conduit 5 is tilted upward, the power actuator 6 can also be tilted, thereby saving the need to increase the distance between the two mold cores 4 when it is set horizontally, effectively reducing the lateral size of the mold. The mold made in this way is smaller in size and smaller in volume, avoiding the use of high-power injection molding machines for injection molding, facilitating operation, and saving energy consumption.

[0018] The power actuator 6 is a hydraulic cylinder or a pneumatic cylinder, the main body of which is fixed to the side core block 43 and the movable end is connected to the middle module 2. When the power actuator 6 is actuated, the main body and the side core block 43 move together with the middle module 2, facilitating injection molding or removal of the molded workpiece.

[0019] Furthermore, a T-joint 7 is fixed to the movable end of the power actuator 6. The cylindrical portions 71 on either side of the T-joint 7 are recessed into grooves 81 of the U-shaped member 8, which is fixedly connected to the middle module 2. With the T-joint 7, the power actuator 6 can be more conveniently installed on the side core block 43 and the middle module 2.

[0020] In addition, the bottom of the core seat 41 is connected to the lower module 3, and the lower module 3 is connected to the middle module 2 and the upper module 1 through the sleeve 9 and the slide 10. This facilitates the separation of the lower module 3 and the middle module 2.

[0021] To further reduce the mold's size, the power actuators 6 are mounted on the outsides of the side core blocks 43. Each mold core has two actuators 6, positioned opposite each other. Connecting arms 11 connect the side core blocks 43 with the actuators 6 and the adjacent side core blocks on either side. These arms 11 are fixed to one of the side core blocks 43 and movably connected to the other side core blocks 43. Only two power actuators 6 are required to engage or disengage the four side core blocks 43, reducing mold production costs and facilitating the synchronous movement of the surrounding side core blocks 43.

[0022] The corners of the side core blocks 43 are provided with second grooves 431, and the connecting arm 11 is provided with protrusions 111, which sink into the second grooves 431 to connect the connecting arm 11 to the side core blocks 43. When the side core blocks 43 move, the protrusions 111 can move in the second grooves 431 while pushing the side core blocks 43 to move, thereby achieving the joining or separation of the surrounding side core blocks 43.

[0023] In order to ensure the precise movement of the side core blocks 43 , each side core block 43 is slidably connected to two guide tubes 5 , which are fixed on the middle module 2 .
