[0028] In the current injection molding production field, traditional ejection and cut-off methods present numerous problems for products with extremely high requirements for appearance. With the rapid development of industries such as consumer electronics and high-end toys, product appearance design increasingly pursues the ultimate in smoothness and seamlessness. Many products cannot have ejection pin marks on the bottom, otherwise it will affect the product's aesthetics and quality, reducing its market competitiveness. Therefore, how to achieve product ejection and demolding without compromising the product's aesthetics and quality has become a pressing technical problem that needs to be solved.

[0029] This utility model proposes a mold structure.

[0030] Please see Figures 1 to 7In one embodiment of this utility model, the mold structure includes: a mold body 100, a demolding mechanism 400, and an ejector pin 530 assembly. The mold body 100 has a cavity adapted to the product 10. The mold body 100 also has a flow channel 200 communicating with the cavity, which allows raw material fluid to flow into the cavity and form the product 10 within it. The mold body 100 also has a molding part 300, one end of which extends into the cavity, and the product 10 is formed on the molding part 300. Above; the demolding mechanism 400 is located on the mold body 100, and the end of the mold part 300 away from the cavity is fixedly connected to the demolding mechanism 400; the lifting assembly 500 is movably connected to the mold body 100 and is connected to the demolding mechanism 400 and the runner 200 respectively. The lifting assembly 500 moves along the first direction and has a lifting position. The movement of the lifting assembly 500 drives the demolding mechanism 400 and the runner 200 to move synchronously along the first direction. In the lifting position, both the product 10 and the runner 200 leave the mold body 100.

[0031] It should be noted that the mold body 100 has a closed state and an open state. In the closed state, the mold part 300 cooperates with the cavity to form the raw material fluid into product 10. In the open state, product 10 is still formed on the mold part 300. The raw material can be a heated and melted injection molding material or a molten casting material. The runner 200 is a tubular structure for the flow of raw material fluid and is connected to the cavity. In order to ensure the quality and fullness of product 10, the raw material fluid is also formed into a raw material solid within the runner 200 and integrally formed with product 10.

[0032] refer to Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the mold body 100 is provided with a cavity, the raw material fluid flows into the cavity, and the mold part 300 extends into the cavity and cooperates with the cavity to form the product 10. The product 10 is formed on the mold part 300, and the mold part 300 moves in a first direction and drives the product 10 to move synchronously. The mold part 300 is also fixedly connected to the demolding mechanism 400. In specific implementation, the demolding mechanism 400 is movably disposed in the groove of the mold body 100, and the lifting component 500 extends into the groove and is fixedly connected to the bottom of the demolding mechanism 400, thereby driving the demolding mechanism 400 to move in the first direction. The first direction can be horizontal or vertical. In this embodiment, the first direction is vertical. The lifting component 500 drives the demolding mechanism 400 to lift vertically, and causes the mold part 300 to lift synchronously, thereby lifting the product 10 away from the cavity. It can be understood that at this time, the mold is in an open state, the cavity is open, and the product 10 can be lifted away from the cavity. In the open mold state, the runner 200 is exposed. Lifting the runner 200 allows it to detach from the mold body 100. Of course, the mold body 100 has a cavity for the runner 200 that is adapted to and accommodates it; this will not be described in detail here. In this embodiment, the lifting assembly 500 is also partially connected to the runner 200. The lifting assembly 500 can be detachably connected to the runner 200 via snap-fit ​​or plug-in methods. Moving the lifting assembly 500 along a first direction causes the runner 200 to lift away from the mold body 100. Furthermore, the lifting assembly 500 drives the demolding mechanism 400 to move synchronously with the runner 200, thereby preventing the product 10 from being pulled and scratched on its surface.

[0033] The present invention employs a flow channel 200 in the mold body 100 for the flow of raw material fluid, and a cavity adapted to the product 10 is also provided in the mold body 100. The raw material fluid flows into the cavity through the flow channel 200, and the mold part 300 cooperates with the cavity to form the product 10. The product 10 is formed on the mold part 300, that is, the product 10 and the mold part 300 are in a state of mutual contact and connection. The lifting assembly 500 is used to lift the runner 200 and the product 10. The mold part 300 is connected to the demolding mechanism 400. The lifting assembly 500 is connected to both the demolding mechanism 400 and the runner 200. The lifting assembly 500 drives the demolding mechanism 400 to move along a first direction and simultaneously drives the runner 200 to move away from the mold. The movement of the demolding mechanism 400 also drives the mold part 300 to move, thereby causing the product 10 to move away from the cavity. In this way, the lifting assembly 500 drives the product 10 to move through the demolding assembly and the mold part 300 without directly contacting the product 10. This avoids ejection marks on the outer wall of the product 10, ensuring the aesthetics and quality of the product 10 and improving its market competitiveness.

[0034] refer to Figure 2As shown, in one embodiment, the lifting assembly 500 includes a top plate 510 and a push rod 520 and an ejector pin 530 disposed on the top plate 510. The push rod 520 is fixedly connected to the demolding mechanism 400, and the ejector pin 530 is connected to the runner 200. The top plate 510 is externally connected to a lifting drive member, which drives the top plate 510 to move along a first direction, thereby causing the push rod 520 and the ejector pin 530 to move, so as to push the demolding mechanism 400 and the runner 200 to move.

[0035] In this embodiment, a lifting space is provided below the mold assembly, and the top plate 510 is located in the lifting space. One side of the top plate 510 is connected to a lifting drive component (not shown in the figure) that drives the top plate 510 to move. The lifting drive component can be a power structure such as a cylinder. The other side of the top plate 510 is fixedly connected to a push rod 520 and an ejector pin 530. The end of the push rod 520 away from the top plate 510 extends along the first direction and is fixedly connected to the demolding mechanism 400 through a bolt or other connecting component 432. The end of the ejector pin 530 away from the top plate 510 extends along the first direction and is inserted into the flow channel 200.

[0036] In addition, it should be noted that the number of push rods 520 and ejector pins 530, as well as the shape and size of the runner 200, should be reasonably set according to the number of products 10 formed by the mold body 100, so as to ensure that the products 10 and the runner 200 can be lifted stably.

[0037] refer to Figure 5 As shown, in one embodiment, the flow channel 200 is provided with a discharge port, and the cavity is provided with a feed port. The feed port and the discharge port are opposite to and connected to each other. The raw material fluid flows into the cavity from the discharge port and the feed port. The raw material fluid forms a raw material entity in the flow channel 200. The raw material entity is integrally formed with the product 10.

[0038] In this embodiment, the runner 200 has an outlet, and the cavity has an inlet. The outlet and inlet correspond to and are connected. It is understood that, to avoid overflow, the outlet and inlet are fitted together, and the product 10 and the runner 200 separate at the outlet and inlet. For the aesthetic appearance of the product 10 and to facilitate easy separation of the product 10 and the runner 200, the size of the outlet needs to be minimized while still allowing for the flow of raw material to complete the injection molding process, thus avoiding large residues on the outer wall of the product 10. In specific implementations, the outlet shape can be circular, square, or other shapes. When the shape is square, the outlet size can be 0.2mm*0.2mm, which has good residue control.

[0039] refer to Figure 5 and Figure 6As shown, in one embodiment, the demolding mechanism 400 includes a base 410, a slider 420, and a drive assembly 430. The lifting assembly 500 is connected to the base 410. The slider 420 is slidably disposed on the side of the base 410 away from the push rod 520. The molded part 300 is fixedly connected to the slider 420. The frictional force between the molded part 300 and the product 10 is greater than the holding force between the product 10 and the flow channel 200. In the lifted position, the drive assembly 430 is driven to connect with the slider 420 and drives the slider 420 to slide along the second direction, causing the product 10 to break away from the flow channel 200 from the feed port and leave the flow channel 200. The first direction is perpendicular to the second direction.

[0040] refer to Figure 7 As shown, the demolding mechanism 400 is also used to drive the molded part 300 away from the product 10. The demolding mechanism 400 pulls the molded part 300, thereby separating the molded part 300 from the product 10. Of course, when the demolding mechanism 400 pulls the product 10 away from the runner 200, the product 10 and the runner 200 have already been lifted away from the mold body 100, that is, the lifting assembly 500 is in the lifting position at this time.

[0041] In this embodiment, the push rod 520 is fixedly connected to the base 410, the slider 420 slides on the base 410 along the second direction, and the drive assembly 430 is fixed on the mold body 100. Specifically, the top surface of the base 410 is provided with a guide groove, and the slider 420 is slidably disposed in the guide groove. The mold part 300 is fixed on the side of the slider 420 facing the product 10. The drive assembly 430 drives the slider 420 to slide horizontally and pulls the mold part 300 to move horizontally, while simultaneously driving the product 10 to move horizontally and break apart from the runner 200, thereby achieving automatic gate breaking without manual operation, improving production efficiency and reducing labor costs. It should be noted that the mold 300 is used to form a through hole on the product 10. The through hole of the product 10 is opened in the horizontal direction. The mold 300 drives the product 10 to move in the horizontal direction, thereby separating the product 10 from the solid of the flow channel 200. It can be understood that in the specific implementation process, the frictional force between the mold 300 and the product 10 is greater than the holding force of the connection between the product 10 and the solid of the flow channel 200, so that the product 10 and the solid of the flow channel 200 can be easily broken. Furthermore, the size of the connection between the solid of the flow channel 200 and the product 10 is small. In the actual production process, the automatic separation of the product 10 and the solid of the flow channel 200 can be fully realized. It should also be noted that in this embodiment, the first direction is perpendicular to the second direction, as shown in the reference. Figure 1 As shown, the first direction is vertical, and the second direction is horizontal.

[0042] Continue to refer to Figure 7As shown, the base 410 is further provided with a blocking part 411. One end of the molded part 300 is connected to the slider 420, and the other end passes through the blocking part 411 and is connected to the product 10. The slider 420 slides and drives the molded part 300 to move so that the product 10 abuts against the blocking part 411 and leaves the molded part 300.

[0043] In the specific implementation process, the blocking part 411 is located on the top of the base 410 and near the product 10, protruding from the top surface of the base 410. When the molded part 300 moves through the blocking part 411, and the slider 420 drives the molded part 300 to move horizontally away from the flow channel 200, the molded part 300 pulls the product 10 to move synchronously until the edge of the product 10 contacts the blocking part 411. At this point, the slider 420 drives the molded part 300 to continue moving, causing the molded part 300 to detach from the product 10, thereby achieving automatic detachment of the product 10. Furthermore, the blocking part 411 and the base 410 are integrally formed to improve their strength.

[0044] In one embodiment, the molding component 300 includes a connecting plate 310 and a molding rod 320. The connecting plate 310 is disposed on the side of the slider 420 facing the product 10. One end of the molding rod 320 is connected to the connecting plate 310, and the other end passes through the blocking part 411 and is connected to the product 10.

[0045] In this embodiment, the molding rod 320 mates with the cavity to form the product 10, and the connecting plate 310 is connected to the slider 420 to facilitate the replacement of different molding parts 300 according to different products 10, thereby improving the applicability of the mold structure. In specific implementation, one end of the molding rod 320 is fixedly connected to the connecting plate 310, such as through integral molding or welding. The molding rod 320 passes through the blocking part 411 and slides along the blocking part 411. The connecting plate 310 is fixed to the side of the slider 420 facing the product 10 by bolts and slides synchronously with the slider 420.

[0046] refer to Figure 5 As shown, in one embodiment, the drive component 430 is disposed on the mold body 100, the slider 420 is provided with a limiting groove 421, and one end of the drive component 430 is movably disposed in the limiting groove 421.

[0047] Specifically, the drive assembly 430 is fixed on the mold body 100. The drive assembly 430 drives the slider 420 to move horizontally, and the slider 420 and the base 410 also move vertically. Thus, in this embodiment, a limiting groove 421 is provided on one side of the slider 420, and the limiting groove 421 extends vertically. One end of the drive assembly 430 used to connect to the slider 420 is movably disposed in the limiting groove 421 to avoid restricting the movement of the slider 420 in the vertical direction. In addition, the limiting groove 421 restricts the drive assembly 430 from disengaging from the slider 420 in the horizontal direction, so that the drive assembly 430 pulls the slider 420 to slide horizontally by connecting the slider 420 with one end located in the limiting groove 421.

[0048] Furthermore, the drive assembly 430 includes a drive body 431 and a connector 432. The drive body 431 is fixedly mounted on the mold body 100. The connector 432 is provided with a connecting part and a limiting part. The limiting part is located in the limiting groove 421. The slider 420 is also provided with a clearance opening 422 that communicates with the limiting groove 421. The connecting part moves through the clearance opening 422 and connects to the drive body 431.

[0049] In this embodiment, the drive body 431 is fixed on the mold body 100. The drive body 431 can be a power component such as a motor or a cylinder. The connector 432 is fixed on the output end of the drive body 431. The limiting part of the connector 432 is movably located in the limiting groove 421. The connecting part extends out of the limiting groove 421 through the clearance opening 422 and connects to the drive body 431. In the horizontal direction, when the drive assembly 430 drives the slider 420 to slide, the limiting part abuts against the inner wall of the limiting groove 421. When the slider 420 moves in the vertical direction, the slider 420 moves relative to the limiting part through the limiting groove 421 and also moves relative to the connecting part through the clearance opening 422, so that the movement of the slider 420 in the horizontal and vertical directions does not interfere with each other.

[0050] In one embodiment, the mold structure further includes a limiting plate 110 and a limiting switch 600. The limiting plate 110 is disposed on the mold body 100, and the limiting switch 600 is disposed on the limiting plate 110 for sensing the distance between the demolding mechanism 400 and the limiting plate 110. The limiting switch 600 is communicatively connected to the demolding mechanism 400.

[0051] Specifically, the limiting plate 110 is fixedly connected to the side of the mold body 100, and the limiting switch 600 is located on one side of the limiting plate 110. When the driving component 430 drives the slider 420 to slide horizontally and triggers the limiting switch 600, the limiting switch 600 generates a trigger signal. The controller controls the driving component 430 to stop according to the trigger signal, thereby stopping the slider 420 from sliding. In specific implementation, the limiting switch 600 can be a limit switch, where the slider 420 contacts and triggers the limit switch. Alternatively, the limiting switch 600 can be a photoelectric switch to sense the distance of the slider 420. When the slider 420 reaches a predetermined distance position, the limiting switch 600 is triggered.

[0052] refer to Figure 4 As shown, in one embodiment, cavities are provided on both sides of the flow channel 200, and the two sets of cavities are symmetrically arranged. Each set of cavities is provided with a set of mold parts 300, and the demolding mechanism 400 is provided with two symmetrical sets.

[0053] In this embodiment, the mold body 100 has two rows of cavities, and the flow channel 200 is located between the two rows of cavities and connects to the two rows of cavities respectively. Each row of cavities has multiple cavities, so multiple products 10 can be molded in one injection molding. It can be understood that each row of cavities corresponds to a set of demolding mechanisms 400, and also corresponds to a set of push rods 520.

[0054] refer to Figure 3 As shown, in one embodiment, the mold body 100 includes an upper mold 120 and a lower mold 130 that are detachably connected, and the two form a cavity and a flow channel 200. The demolding mechanism 400 and the lifting mechanism are both located in the lower mold 130. The upper mold 120 and the lower mold 130 have an open mold state and a closed mold state. In the closed mold state, the raw material fluid is formed into a product 10. In the open mold state, the lifting component 500 drives the demolding mechanism 400 and the flow channel 200 to move.

[0055] Understandably, the upper mold 120 and the lower mold 130 fit together to achieve mold closing and injection molding of product 10. The upper mold 120 and the lower mold 130 separate to achieve mold parting, allowing for the ejection and separation of product 10 and runner 200, and enabling automatic detachment of product 10. Both the upper mold 120 and the lower mold 130 have mold cores, and the cavity is formed in the mold cores. The two mold cores fit together to form the cavity. Different mold cores can be replaced according to different products 10, improving the applicability of the mold structure. It should be further explained that, in the mold-closed lifting state, the lifting component 500 lifts the product 10 and the runner 200 away from the lower mold 130. After the lifting is completed and the lifting component 500 is in the lifting position, the demolding mechanism 400 drives the mold part 300 to move horizontally to pull the product 10 to move and separate it from the runner 200. The demolding mechanism 400 drives the mold part to continue moving, causing the product 10 to abut against the blocking part 411 of the base 410. During the continued movement, the product 10 is disengaged from the mold part 300, thereby realizing the automatic release of the product 10.

[0056] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
