Description

Technical Field

[0001] This invention belongs to the technical field of molds, and particularly relates to a multi-segment molding mold. Background Technology

[0002] Injection molds are production equipment used to inject molten plastic material into a mold cavity, which then cools and solidifies to obtain a molded product. In conventional mold structures, the fixed mold side cavity and the moving mold side cavity are usually in fixed positions. Therefore, when the final product is made of various plastic materials with different properties, composed of various different shapes, or does not meet the conditions for complete demolding (such as a plastic box for wrapping an item), it is necessary to complete the initial injection molding on one injection molding machine and then place it on another injection molding machine for a second injection molding to complete the production of a complete product. This results in low production efficiency and increased costs for equipment use, labor, and warehousing. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-segment molding die, which enables multiple injection molding processes on the same die to form a complete product composed of various plastic materials with different properties, various shapes, or products that do not meet the conditions for complete demolding. This improves production efficiency and reduces equipment usage costs, labor costs, and warehousing costs.

[0004] The multi-segment molding die includes a moving mold plate and a fixed mold plate. The moving mold plate is equipped with a moving mold side rotating wheel and a moving mold side motor that drives the moving mold side rotating wheel. A moving mold side rotating mold core is installed on the moving mold side rotating wheel. A moving mold side movable cavity is provided on the moving mold side rotating mold core. The fixed mold plate is equipped with a fixed mold side fixed mold core and a fixed mold side movable cavity located above the moving mold side movable cavity. The fixed mold side fixed mold core and the fixed mold side movable cavity are respectively provided with feed channels connected to the injection molding machine pipeline.

[0005] According to the technical solution, when the moving mold plate and the fixed mold plate are closed for the first time, the moving cavity on the moving mold side and the fixed mold core on the fixed mold side are combined to injection mold a semi-finished product. After that, the moving mold plate and the fixed mold plate are opened for the first time. The motor on the moving mold side drives the moving cavity on the moving mold side to rotate through the rotating wheel on the moving mold side, so as to move the moving cavity on the moving mold side containing the semi-finished product to below the moving cavity on the fixed mold side. After that, the moving mold plate and the fixed mold plate are closed for the second time, and the moving cavity on the moving mold side and the moving cavity on the fixed mold side are combined to injection mold a semi-finished product.

[0006] This allows the multi-segment molding mold to perform multiple injection moldings on the same mold to form a complete product with different plastic materials for each part, thereby improving production efficiency and reducing equipment usage costs, labor costs, and warehousing costs.

[0007] In some embodiments, the rotating mold core on the moving mold side is provided with at least two moving mold side movable cavities, the fixed mold core on the fixed mold side is located directly above one part of the moving mold side movable cavities, and the fixed mold side movable cavity is located directly above another part of the moving mold side movable cavities; according to the above technical solution, multiple moving mold side movable cavities can be alternately combined with the fixed mold core and the fixed mold side movable cavity for injection molding, thereby improving injection molding efficiency.

[0008] In some embodiments, the fixed mold core on the fixed mold side is provided with a fixed mold side ejector pin, and the fixed mold side ejector pin is provided with a fixed mold side push plate; according to the above technical solution, during the first mold opening, the injection molding machine drives the fixed mold side ejector pin through the fixed mold side push plate to separate the semi-finished product from the fixed mold core on the fixed mold side, so that the semi-finished product remains more stably in the moving mold side moving cavity and moves to the bottom of the fixed mold side moving cavity.

[0009] In some embodiments, a moving mold side rotating mold core is provided at its center and mounted on the moving mold plate; according to the above technical solution, the moving mold side rotating mold core and the moving mold side rotating wheel are supported, so that the moving mold side rotating mold core and the moving mold side rotating wheel do not contact the moving mold plate, thereby reducing the frictional force generated between the moving mold side rotating mold core and the moving mold side rotating wheel and the moving mold plate.

[0010] In some embodiments, the moving mold plate is equipped with a moving mold side fixed mold core, the fixed mold plate is equipped with a fixed mold side rotating wheel and a fixed mold side motor that drives the fixed mold side rotating wheel, the fixed mold side rotating mold core is installed on the fixed mold side rotating wheel, and the fixed mold side movable cavity is provided with at least two fixed mold side movable cavities, one of which is located directly above the moving mold side movable cavity, and the moving mold side fixed mold core is located directly below the other part of the fixed mold side movable cavity;

[0011] According to the technical solution, when the moving mold plate and the fixed mold plate perform the first mold closing, the moving cavity on the moving mold side and the fixed mold core on the fixed mold side are combined and injection molded into a semi-finished product. At the same time, the fixed mold core on the moving mold side and the moving cavity on the fixed mold side are combined and injection molded into another semi-finished product. After that, the moving mold plate and the fixed mold plate open for the first mold opening. The moving mold side motor drives the moving cavity on the moving mold side to rotate through the moving mold side rotating wheel, so as to move the moving cavity on the moving mold side containing the semi-finished product to below the moving cavity on the fixed mold side. At the same time, the fixed mold side motor drives the moving cavity on the fixed mold side to rotate through the fixed mold side rotating wheel, so as to move the moving cavity on the fixed mold side containing the other semi-finished product to above the moving cavity on the moving mold side (that is, above the first half of the finished product). After that, the moving mold plate and the fixed mold plate perform the second mold closing, and the moving cavity on the moving mold side and the moving cavity on the fixed mold side are combined and injection molded to connect the two semi-finished products.

[0012] This allows the multi-segment molding mold to assemble semi-finished products of different shapes into a complete product on the same mold, or to form a complete product by injection molding multiple times using plastic materials with different properties in each part, or to disassemble a complete product that does not meet the conditions for complete demolding, then injection mold it and then reassemble it, thereby improving production efficiency and reducing the cost of equipment use, labor and warehousing.

[0013] In some embodiments, the top wall of the movable cavity on the fixed mold side is provided with a movable insert that can be ejected downwards. A reset plate is installed on the top of the movable insert. A spring hole is provided next to the movable insert. A first reset spring connected to the reset plate is placed in the spring hole. A push rod is passed through the fixed mold plate and is located above the movable cavity on the moving mold side, the movable cavity on the fixed mold side, and the reset plate. A shim is fixed at the top of the push rod. A second reset spring is directly provided between the shim and the fixed mold plate. A pressure plate for pressing down the shim is provided above the fixed mold plate.

[0014] According to the technical solution, during the second mold closing of the moving mold plate and the fixed mold plate, the injection molding machine drives the pressure plate to press down the pressure pad, so that the pressure pad pushes the moving insert out of the moving cavity on the fixed mold side through the push rod, thereby pushing out the semi-finished product in the moving cavity on the fixed mold side and pressing it onto the semi-finished product in the moving cavity on the moving mold side, and freeing up space in the moving cavity on the fixed mold side to inject plastic material, thereby realizing the sealing and encapsulation of a local part of the product in the same mold.

[0015] In some embodiments, the moving mold side fixed mold core is provided with a moving mold side fixed cavity that can enter the fixed mold side movable cavity; according to the above technical solution, a portion of the fixed mold side movable cavity is filled during the first mold closing injection, so that more space is available for injecting plastic material for overmolding during the second mold closing.

[0016] In some embodiments, the fixed cavity on the moving mold side is provided with a moving mold side ejector pin, and the moving mold side ejector pin is provided with a moving mold side push plate; according to the above technical solution, during the first mold opening, the injection molding machine drives the moving mold side ejector pin through the moving mold side push plate to separate the other semi-finished product from the fixed mold core on the moving mold side, thereby making the semi-finished product more stably stay in the moving cavity on the fixed mold side and move to the top of the moving cavity on the moving mold side.

[0017] In some embodiments, a fixed mold side rotating mold core is provided at its center and mounted on a fixed mold plate; according to the above technical solution, the fixed mold side rotating mold core and the fixed mold side rotating wheel are supported, so that the fixed mold side rotating mold core and the fixed mold side rotating wheel do not contact the fixed mold plate, thereby reducing the frictional force generated between the fixed mold side rotating mold core and the fixed mold side rotating wheel and the fixed mold plate.

[0018] In some embodiments, the rotating mold core on the moving mold side has four movable cavities on the moving mold side, which are symmetrical about the central axis of the rotating mold core on the moving mold side. The fixed mold core on the fixed mold side is located above two of the rotating mold cores on the moving mold side on one side. The rotating mold core on the fixed mold side has four movable cavities on the fixed mold side, which are symmetrical about the central axis of the rotating mold core on the fixed mold side. Two of the movable mold cores on one side are located above two of the rotating mold cores on the moving mold side on the other side, and the fixed mold core on the moving mold side is located above two of the movable mold cores on the other side. According to the above technical solution, the injection volume during a single mold closing can be increased, thereby further improving the injection molding efficiency. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0028] like Figures 1 to 5 As shown in the figure, this specific embodiment provides a multi-segment molding die, which includes a moving mold plate 1 and a fixed mold plate 2. The moving mold plate 1 is equipped with a moving mold side rotating wheel 11 and a moving mold side motor 12 that drives the moving mold side rotating wheel 11. A moving mold side rotating mold core 13 is installed on the moving mold side rotating wheel 11. The moving mold side rotating mold core 13 is provided with a moving mold side movable cavity 131. The fixed mold plate 2 is equipped with a fixed mold side fixed mold core 25 and a fixed mold side movable cavity 231 located above the moving mold side movable cavity 131. The fixed mold side fixed mold core 25 and the fixed mold side movable cavity 231 are respectively provided with feed channels 24 connected to the injection molding machine pipe.

[0029] During operation, the moving mold plate 1 and the fixed mold plate 2 perform the first mold closing, and the moving cavity 131 on the moving mold side and the fixed mold core 25 on the fixed mold side are combined to injection mold the lower shell product 3. After that, the moving mold plate 1 and the fixed mold plate 2 open the mold for the first time. The moving mold side motor 12 drives the moving cavity 131 on the moving mold side to rotate through the moving mold side rotating wheel 11, so as to move the moving cavity 131 containing the lower shell product 3 to below the moving cavity 231 on the fixed mold side. After that, the moving mold plate 1 and the fixed mold plate 2 perform the second mold closing, and the moving cavity 131 on the moving mold side and the moving cavity 231 on the fixed mold side are combined to injection mold the lower shell product 3 for a second injection.

[0030] In some embodiments, the rotating mold core 13 on the moving mold side is provided with at least two moving mold side movable cavities 131, the fixed mold core 25 on the fixed mold side is located directly above one of the moving mold side movable cavities 131, and the fixed mold side movable cavity 231 is located directly above the other part of the moving mold side movable cavity 131.

[0031] During the second mold closing of the moving mold plate 1 and the fixed mold plate 2, the moving cavity 131 on the moving mold side containing the lower shell product 3 is injection molded together with the moving cavity 231 on the fixed mold side. At the same time, the other moving cavity 131 on the moving mold side is injection molded together with the fixed mold core 25 on the fixed mold side to form the lower shell product 3.

[0032] In some embodiments, the fixed mold core 25 on the fixed mold side is provided with a fixed mold side ejector pin 251, and the fixed mold side ejector pin 251 is provided with a fixed mold side push plate 252;

[0033] During the first mold opening, the injection molding machine drives the fixed mold side push plate 252 to descend, and the fixed mold side push plate 252 drives the fixed mold side ejector pin 251 to eject the lower shell product 3 and separate it from the fixed mold core 25 on the fixed mold side.

[0034] In some embodiments, the center of the rotating mold core 13 on the moving mold side is provided with a rotating mold side bearing 10 mounted on the moving mold plate 1 to support the rotating mold core 13 on the moving mold side and the rotating wheel 11 on the moving mold side, thereby preventing the rotating mold core 13 on the moving mold side and the rotating wheel 11 on the moving mold side from contacting the moving mold plate 1 and reducing the frictional force generated between the rotating mold core 13 on the moving mold side and the rotating wheel 11 on the moving mold side and the moving mold plate 1.

[0035] In some embodiments, the moving mold plate 1 is equipped with a moving mold side fixed mold core 14, the fixed mold plate 2 is equipped with a fixed mold side rotating wheel 21 and a fixed mold side motor 22 that drives the fixed mold side rotating wheel 21, a fixed mold side rotating mold core 23 is installed on the fixed mold side rotating wheel 21, and the fixed mold side movable cavity 231 is provided with at least two fixed mold side movable cavities 231, one of which is located directly above the moving mold side movable cavity 131, and the moving mold side fixed mold core 14 is located directly below the other part of the fixed mold side movable cavity 231;

[0036] During operation, when the moving mold plate 1 and the fixed mold plate 2 close for the first time, the moving cavity 131 on the moving mold side merges with the fixed mold core 25 on the fixed mold side to injection mold the lower shell product 3. At the same time, the fixed mold core 14 on the moving mold side merges with the moving cavity 231 on the fixed mold side to injection mold another upper cover product 4. After that, the moving mold plate 1 and the fixed mold plate 2 open for the first time. The moving mold side motor 12 drives the moving cavity 131 on the moving mold side to rotate through the moving mold side rotating wheel 11, so as to move the moving cavity 131 containing the lower shell product 3 to the fixed mold. Below the side moving cavity 231, the fixed mold side motor 22 drives the fixed mold side moving cavity 231 to rotate via the fixed mold side rotating wheel 21, so as to move the fixed mold side moving cavity 231 containing the upper cover product 4 to above the moving mold side moving cavity 131 (that is, above the moving mold side moving cavity 131 containing the lower shell product 3). After that, the moving mold plate 1 and the fixed mold plate 2 perform a second mold closing, and the moving mold side moving cavity 131 and the fixed mold side moving cavity 231 are combined for injection molding to splice the upper cover product 4 and the lower shell product 3.

[0037] Based on the above-described scheme, the following features can be further selected and supplemented: the top wall of the fixed mold side movable cavity 231 is provided with a downward ejectable movable insert 232, the top of the movable insert 232 is equipped with a reset plate 233, a spring hole 234 is provided next to the movable insert 232, a first reset spring 235 connected to the reset plate 233 is placed in the spring hole 234, the fixed mold plate 2 is provided with a lower push rod 236 that is simultaneously located above the moving mold side movable cavity 131, the fixed mold side movable cavity 231 and the reset plate 233, the top of the lower push rod 236 is fixed with a shim 237, the shim 237 and the fixed mold plate 2 are directly provided with a second reset spring 238, and a pressure plate 239 that presses down on the shim 237 is provided above the fixed mold plate 2;

[0038] When the moving mold plate 1 and the fixed mold plate 2 are closed for the second time, the injection molding machine drives the pressure plate 239 to descend. The descending pressure plate 239 presses down the gasket 237, so that the pressing gasket 237 pushes the moving insert 232 out of the moving cavity 231 on the fixed mold side through the lower push rod 236. This pushes out the upper cover product 4 in the moving cavity 231 on the fixed mold side and presses it onto the lower shell product 3 in the moving cavity 131 on the moving mold side. This frees up space in the moving cavity 231 on the fixed mold side to inject plastic material, so as to fix the upper cover product 4 on the lower shell product 3 with glue.

[0039] Based on the above-described scheme, the following feature can be further selected and added: the moving mold side fixed mold core 14 is provided with a moving mold side fixed cavity 141 that can enter the fixed mold side movable cavity 231;

[0040] When the moving mold plate 1 and the fixed mold plate 2 are closed for the first time, the fixed cavity 141 on the moving mold side is located in the moving cavity 231 on the fixed mold side. The periphery of the cavity of the fixed cavity 141 on the moving mold side fills the position in the moving cavity 231 on the fixed mold side where no plastic is to be injected, so that when the moving mold plate 1 and the fixed mold plate 2 are opened for the first time, there is a reserved space for the top cover product 4 in the moving cavity 231 on the fixed mold side for plastic wrapping.

[0041] Based on the above-described scheme, the following features can be further selected and added: the moving mold side fixed cavity 141 is provided with a moving mold side ejector pin 142, and the moving mold side ejector pin 142 is provided with a moving mold side push plate 143.

[0042] During the first mold opening, the injection molding machine drives the moving mold side push plate 143 to rise, and the moving mold side push plate 143 drives the moving mold side ejector pin 142 to lift the upper cover product 4 and separate it from the moving mold side fixed mold core 14.

[0043] Based on the above-described scheme, the following feature can be further selected and added: the center of the fixed mold side rotating mold core 23 is provided with a fixed mold side bearing 20 installed on the fixed mold plate 2 to support the fixed mold side rotating mold core 23 and the fixed mold side rotating wheel 21, so that the fixed mold side rotating mold core 23 and the fixed mold side rotating wheel 21 do not contact the fixed mold plate 2, thereby reducing the frictional force generated between the fixed mold side rotating mold core 23 and the fixed mold side rotating wheel 21 and the fixed mold plate 2.

[0044] Based on the above-described scheme, the following features can be further selected and supplemented: the moving mold side rotating mold core 13 is provided with 4 moving mold side movable cavities 131, the 4 moving mold side movable cavities 131 are symmetrical about the central axis of the moving mold side rotating mold core 13, and the fixed mold side fixed mold core 25 is located above the two moving mold side rotating mold cores 13 on one side; the fixed mold side rotating mold core 23 is provided with 4 fixed mold side movable cavities 231, the 4 fixed mold side movable cavities 231 are symmetrical about the central axis of the fixed mold side rotating mold core 23, the two fixed mold side movable cavities 231 on one side are located above the two moving mold side rotating mold cores 13 on the other side, and the moving mold side fixed mold core 14 is located above the two fixed mold side movable cavities 231 on the other side.

[0045] The technical features described in the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. Furthermore, to more clearly understand the effects, functions, and advantages of the combinations of technical features in certain embodiments of the present invention, the following embodiments are provided as examples.

The fixed mold side movable cavity 231 is provided with a feed channel 24 connected to the injection molding machine pipeline.

[0059] The following is the working process of a multi-segment molding die described in this embodiment:

[0060] When the moving mold plate 1 and the fixed mold plate 2 are closed for the first time, the two moving mold side movable cavities 131 located on one side merge with the fixed mold side fixed mold core 25 to injection mold the lower shell product 3. At the same time, the two moving mold side fixed mold cores 14 located on one side merge with the fixed mold side movable cavity 231. The moving mold side fixed cavity 141 is located in the fixed mold side movable cavity 231. The injection molding machine injection molds the moving mold side fixed cavity 141 to form the upper cover product 4.

[0061] Subsequently, the moving mold plate 1 and the fixed mold plate 2 open for the first time. The injection molding machine drives the fixed mold side push plate 252 to descend. The fixed mold side push plate 252 drives the fixed mold side ejector pin 251 to eject the lower shell product 3 and separate it from the fixed mold core 25 on the fixed mold side. The lower shell product 3 remains in the moving cavity 131 on the moving mold side. At the same time, the injection molding machine drives the moving mold side push plate 143 to rise. The moving mold side push plate 143 drives the moving mold side ejector pin 142 to lift the upper cover product 4 and separate it from the fixed mold core 14 on the moving mold side. The upper cover product 4 remains in the moving cavity 231 on the fixed mold side.

[0062] Subsequently, the moving mold side motor 12 drives the moving mold side movable cavity 131 to rotate via the moving mold side rotating wheel 11, so as to move the moving mold side movable cavity 131 containing the lower shell product 3 to below the fixed mold side movable cavity 231. At the same time, the fixed mold side motor 22 drives the fixed mold side movable cavity 231 to rotate via the fixed mold side rotating wheel 21, so as to move the fixed mold side movable cavity 231 containing the upper cover product 4 to above the moving mold side movable cavity 131 (that is, above the moving mold side movable cavity 131 containing the lower shell product 3).

[0063] Subsequently, the moving mold plate 1 and the fixed mold plate 2 are closed for the second time. The moving mold side movable cavity 131 containing the lower shell product 3 is merged with the fixed mold side movable cavity 231 containing the upper cover product 4. The two empty moving mold side movable cavities 131 are merged with the fixed mold side fixed core 25 to injection mold a new lower shell product 3. The two empty moving mold side fixed cores 14 are merged with the fixed mold side movable cavity 231. The moving mold side fixed cavity 141 is located inside the fixed mold side movable cavity 231. The injection molding machine injection molds the moving mold side fixed cavity 141 to form a new upper cover product 4.

[0064] Subsequently, the injection molding machine drives the pressure plate 239 to descend, which presses down the gasket 237. This causes the pressure gasket 237 to push the movable insert 232 out of the fixed mold side movable cavity 231 via the push rod 236. This pushes the upper cover product 4 out of the fixed mold side movable cavity 231 and presses it onto the lower shell product 3 in the moving mold side movable cavity 131, freeing up space in the fixed mold side movable cavity 231 for the injection of plastic material, so that the upper cover product 4 can be glued onto the lower shell product 3.
