Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of injection mold, and particularly relates to a movable mold structure for producing a turnover basket and an injection mold. BACKGROUND

[0002] The turnover basket, also commonly known as a logistics turnover basket, a logistics turnover box or a logistics box, is a kind of reusable container widely used in logistics, warehousing, production and distribution links.

[0003] Most of the commonly used turnover baskets are integrally formed by using the injection molding process. Figure 1 As shown in a kind of turnover basket, including frame body 1, inner cavity 3 and setting in frame body 1 outside the reverse buckle structure 2. The traditional injection mold is usually set in the movable mold part for forming the inner cavity 3 of the core, and the movable slider is set in the fixed mold part. When the injection mold works, in the opening stage, first, the movable mold is separated from the fixed mold by the injection molding machine, and then the core is taken out of the turnover basket; then drive the slider on the fixed mold side to slide horizontally, so that the reverse buckle structure 2 on it is separated from the frame body 1, and finally the formed turnover basket can be taken out from the fixed mold part.

[0004] Although this operation mode can realize the forming of the turnover basket, there are obvious problems in actual application: because the core is separated from the turnover basket in advance, the turnover basket is suspended only by the adhesion between the fixed mold slider under the condition of losing internal support. When the slider performs the core pulling action (i.e. separates from the reverse buckle structure 2), it is easy to drive the turnover basket to deviate on the fixed mold, so that it cannot be kept in the center position of the fixed mold assembly, but deviates and adheres to one side of the slider. At this time, the turnover basket cannot be automatically taken out, and must rely on the manual operation of the operator, which is difficult to realize automatic production.

[0005] In addition, when the volume of the turnover basket is large (for example: 600mm long, 400mm wide and 200mm high), the operator needs to enter the inside of the injection molding machine to take out the turnover basket between the separated movable mold and fixed mold, which has serious safety hazards and threatens personal safety. SUMMARY

[0006] The present application solves the technical problems of the prior art and provides a movable mold structure for producing a turnover basket and an injection mold.

[0007] The technical scheme adopted by the present application to solve the above technical problems is to provide a movable mold structure for producing a turnover basket, comprising: a movable mold frame;

[0008] A first forming block is arranged on the movable mold frame and used for forming the inner cavity of the turnover basket.

[0009] A plurality of sliders are arranged circumferentially on the first forming block, the sliders are movably arranged on the movable die frame, and the moving direction of the sliders is arranged at an angle with the normal direction of the end face of the movable die frame away from the first forming block;

[0010] A second forming block is arranged at one end of the first forming block towards the first forming block, and the second forming block is used for forming the reverse buckle structure on the turnover basket;

[0011] A middle frame is movably abutted on the movable die frame and sleeved on the outside of the first forming block, and when the middle frame moves relative to the movable die frame, it is used to drive the sliders and the turnover basket to move relative to the movable die frame; wherein,

[0012] When the sliders move, the second forming block is used to separate the reverse buckle structure of the turnover basket at the same time as the turnover basket is separated from the first forming block.

[0013] In the above-mentioned movable die structure for producing a turnover basket, the first forming block is circumferentially arranged with at least two sliders uniformly.

[0014] In the above-mentioned movable die structure for producing a turnover basket, a plurality of sliders are arranged with the second forming block at both ends along the normal direction.

[0015] In the above-mentioned movable die structure for producing a turnover basket, a pushing block is arranged on the middle frame, a lifting block is arranged on the slider, the pushing block and the lifting block are movably abutted, and one end of the pushing block extends into the first forming block to form the end face structure of the turnover basket.

[0016] In the above-mentioned movable die structure for producing a turnover basket, a receiving groove is arranged on the slider, the lifting block is detachably arranged in the receiving groove, and one end of the lifting block extends out of the receiving groove and movably abuts with the pushing block.

[0017] In the above-mentioned movable die structure for producing a turnover basket, the first forming block has four side walls, one slider is arranged on each side wall, four pushing blocks are arranged on the middle frame, one lifting block is arranged on each adjacent side of every two adjacent sliders, and each pushing block is abutted with two lifting blocks at the same time.

[0018] In the above-mentioned movable die structure for producing a turnover basket, the middle frame is a square structure, each inner corner of the middle frame extends towards the first forming block to form a connecting seat, and the pushing block is fixed on the connecting seat.

[0019] In the above-mentioned movable die structure for producing the turnover basket, each of the sliders is provided with an abutting block at one end away from the first forming block, and the abutting block is in movable abutment with the end face of the middle frame towards the movable die frame, for bringing the sliders back to the original position when the middle frame is reset.

[0020] In the above-mentioned movable die structure for producing the turnover basket, further comprising:

[0021] A driving member is installed on the middle frame, and the output end of the driving member is connected to the movable die frame.

[0022] A connecting block is arranged between each two adjacent sliders, for keeping the sliders moving synchronously.

[0024] The present application solves the above-mentioned technical problems and further provides an injection mold comprising the above-mentioned movable die structure for producing the turnover basket.

[0028] (3) By arranging the abutting block on the slider and cooperating with the end face of the middle frame, the sliders can be automatically reset by the middle frame during the mold closing stage, thereby realizing the bidirectional linkage reset of the sliders without the need of additional reset mechanism. This not only simplifies the mold structure and reduces the manufacturing cost, but also improves the reliability and response speed of the action. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0038] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0040] As Figures 1 to 8 shown, a movable mold structure for producing a turnover basket of the present application comprises a movable mold frame 100, a first forming block 200, a second forming block 400, a middle frame 500 and a plurality of sliding blocks 300.

[0041] Specifically, the movable mold frame 100 is configured as the main part of the movable mold structure, and is used to be connected with the driving device of the injection molding machine. Under the driving of the injection molding machine driving device, the movable mold frame 100 can be close to or away from the fixed mold part of the injection mold, so as to realize the mold closing and opening actions.

[0042] In one embodiment, a partition is further provided between the movable mold frame 100 and the injection molding machine driving device. On the one hand, the partition facilitates the installation connection between the movable mold frame 100 and the injection molding machine, and on the other hand, the partition can block heat transfer to prevent heat generated when the movable mold frame 100 is working from being conducted to the injection molding machine body.

[0043] The first forming block 200 is used for forming the inner cavity 3 of the turnover basket and is arranged on the movable mold frame 100. Preferably, the first forming block 200 is located at the center of the movable mold frame 100 and is fixed to the movable mold frame 100 by a threaded connection.

[0044] In one embodiment, the first forming block 200 is internally provided with a cooling water channel to achieve cooling. In another embodiment, the first forming block 200 is further provided with an insert to prevent injection molding defects (such as shrinkage and air marks) on the wall of the inner cavity 3 of the turnover basket.

[0045] The slider 300 is arranged in the circumferential direction of the first forming block 200 and forms a forming space for the outer wall of the turnover basket together with the first forming block 200. The slider 300 is movably installed on the movable mold frame 100, and the moving direction 900 of the slider 300 forms an angle with the normal direction 800 of the end face of the movable mold frame 100 away from the first forming block 200 (the angle is 10°-14°). When the slider 300 moves, the outer wall structure of the formed turnover basket can be separated, facilitating demolding.

[0046] The second forming block 400 is arranged on the slider 300, and at least one end of the slider 300 towards the first forming block 200 is provided with the second forming block 400. The second forming block 400 is used for forming the undercut structure 2 on the turnover basket.

[0047] The middle frame 500 is movably abutted against the movable mold frame 100 and is sleeved on the outside of the first forming block 200. The middle frame 500 serves as a driving component and drives the slider 300 and the formed turnover basket to move relative to the movable mold frame 100 during movement.

[0048] When the middle frame 500 drives the slider 300 to move, since the second forming block 400 is fixed to the slider 300, the formed turnover basket is driven by the middle frame 500 to move away from the first forming block 200. At the same time, the slider 300 moves in an inclined direction, thereby driving the second forming block 400 to be extracted from the undercut structure 2 of the turnover basket.

[0049] During the above demolding process, since the inner cavity 3 of the turnover basket is always in contact with the first forming block 200 until the undercut is completely demolded, the first forming block 200 can provide continuous internal support for the turnover basket, effectively preventing the turnover basket from being deviated to one side of the movable mold structure during core pulling by the second forming block 400, thereby ensuring the accuracy and stability of the demolding position.

[0050] In the present scheme, by arranging the first forming block 200 on the movable mold frame 100 and driving the circumferentially arranged slider 300 to move in an inclined manner under the driving of the middle frame 500, the first forming block 200 is synchronously completed with the withdrawal of the undercut during the demolding process.

[0051] Since the turnover basket is still internally supported by the first forming block 200 at the initial stage of demolding, the problems of turnover basket deviation and adhesion caused by the premature separation of the core in the traditional structure are effectively avoided, and the demolding stability is significantly improved.

[0052] At the same time, this structure ensures that the turnover basket is stably retained on the movable mold side after demolding, facilitating automatic part taking, solving the serious safety hazards caused by manual part taking in the large turnover basket, and greatly improving the production automation degree and operation safety.

[0053] Preferably, the first forming block 200 is circumferentially and uniformly provided with at least two sliding blocks 300.

[0054] By uniformly arranging at least two sliding blocks 300 circumferentially on the first forming block 200, the core pulling action of the undercut structure 2 is simultaneously and symmetrically performed in multiple directions, effectively balancing the stress distribution during demolding, preventing the turnover basket from being twisted or deformed due to uneven stress on one side, and improving the product forming quality and dimensional accuracy. At the same time, the coordinated work of multiple sliding blocks 300 enhances the stability of the overall structure, further ensuring the reliability of the demolding process.

[0055] The second forming block 400 is arranged on the movable mold structure.

[0056] By arranging the second forming block 400 of the two layers of undercut structure 2 on the outer side wall of the turnover basket on the movable mold structure, rather than arranging one layer of undercut structure 2 on the movable mold structure and the fixed mold structure, there are double advantages: on the one hand, during the demolding process of the first forming block 200 and the turnover basket, the second forming block 400 is separated from the undercut structure 2, and the first forming block 200 provides internal support, effectively preventing the molded turnover basket from deviating; on the other hand, when the sliding block 300 moves away from the movable mold frame 100, it can simultaneously drive the two layers of undercut structure 2 and the second forming block 400 to separate, without the need to add additional demolding mechanism on the fixed mold structure, thereby reducing the design and manufacturing difficulty of the injection mold.

[0057] In addition, by arranging the second forming block 400 at both ends of the sliding block 300, the upper and lower undercut structures 2 on the turnover basket can be molded at the same time, realizing integrated molding of bidirectional undercut, without the need to increase additional processes or molding mechanisms. This design improves the integration of the mold, reduces the space occupation, and is especially suitable for large turnover baskets with complex undercut structures 2, significantly enhancing the adaptability and functionality of the mold.

[0058] It is worth mentioning that the middle frame 500 is provided with a pushing block 510, and the sliding block 300 is provided with a lifting block 310, the pushing block 510 and the lifting block 310 are in movable abutment, and one end of the pushing block 510 extends into the first forming block 200 for molding the end face structure of the turnover basket.

[0059] When the middle frame 500 moves relative to the movable mold frame 100, the sliding block 300 can be driven to move in a predetermined direction through the cooperation of the pushing block 510 and the lifting block 310. At the same time, the part of the pushing block 510 extending into the first forming block 200 participates in forming, which can push the formed turnover basket out of the first forming block 200 synchronously during mold opening, realizing the demolding auxiliary action.

[0060] This design not only realizes reliable transmission of the middle frame 500 to the sliding block 300, but also enables the pushing block 510 to have the functions of structural forming and ejection assistance, which can accurately shape the detailed structure of the end face of the turnover basket and improve the structural integrity and appearance quality of the product.

[0061] Further, the sliding block 300 is provided with a containing groove 320, and the lifting block 310 is detachably installed in the containing groove 320, and one end of the lifting block 310 extends out of the containing groove 320 and movably abuts against the pushing block 510.

[0062] The detachable connection between the lifting block 310 and the containing groove 320 can be realized by threaded connection. The lifting block 310 is detachably arranged in the containing groove 320 of the sliding block 300, which facilitates individual replacement after wear without the need for overall replacement of the sliding block 300 or shutdown overhaul, significantly reducing the maintenance difficulty and cost. At the same time, this structure effectively ensures the stability and cooperation precision of the transmission contact surface, ensuring long-term stable and reliable operation of the core-pulling action.

[0063] In a preferred scheme, the first forming block 200 has four side walls, one sliding block 300 is arranged on each side wall, four pushing blocks 510 are arranged on the middle frame 500, one lifting block 310 is arranged on each adjacent side of every two adjacent sliding blocks 300, and each pushing block 510 abuts against two lifting blocks 310 at the same time.

[0064] The four sliding blocks 300 are symmetrically arranged, and the two lifting blocks 310 of every two adjacent sliding blocks 300 are driven at the same time by each pushing block 510, realizing four-way synchronous core-pulling and greatly improving the balance and coordination of the demolding process. This structure is particularly suitable for square or rectangular turnover baskets, which can effectively prevent product deformation or flash defects caused by asynchronous core-pulling, and ensure stable production of large turnover baskets with high quality.

[0065] The middle frame 500 is a square structure, each inner corner of which extends towards the first forming block 200 to form a connecting seat 520, and the pushing block 510 is fixed on the connecting seat 520.

[0066] The pushing block 510 is preferably fixed with the connecting seat 520 through threaded connection. The middle frame 500 installs the pushing block 510 through the connecting seat 520 formed by extending the inner corner thereof towards the first forming block 200, which is compact in structure, reasonable in force, and effectively enhances the connection rigidity and stability between the middle frame 500 and the pushing block 510. The design is beneficial to accurate transmission of driving force, reduces shaking or deviation in the transmission process, ensures accurate driving of the pushing block 510 on the sliding block 300, and further improves the stability and reliability of the mold operation.

[0067] Each sliding block 300 is provided with an abutting block 330 away from the first forming block 200, which movably abuts with the end face of the middle frame 500 towards the movable mold frame 100, and is used to reset the sliding block 300 when the middle frame 500 is reset.

[0068] The abutting block 330 is a transmission structure for resetting the sliding block 300 during the closing process of the injection mold. When the middle frame 500 moves towards the movable mold frame 100, the end face thereof abuts against the abutting block 330 and drives the sliding block 300 to move towards the movable mold frame 100, thereby accurately resetting the sliding block 300. In an embodiment, the movable mold frame 100 is provided with a positioning groove for accommodating the abutting block 330 after the sliding block 300 is reset, so as to ensure the accuracy of the position of the sliding block 300 and the stability of the mold closing.

[0069] In order to further improve the stability and synchronism of the sliding block 300 during movement, two abutting blocks 330 are arranged on each sliding block 300. The abutting blocks 330 are fixed with the sliding block 300 through threaded connection, which is convenient for individual replacement after wear or damage, without the need to replace the entire sliding block 300, thereby reducing maintenance cost.

[0070] By arranging the abutting block 330 on the sliding block 300 and cooperating with the end face of the middle frame 500, the sliding block 300 can be automatically reset by the middle frame 500 during the mold closing stage, realizing bidirectional linkage reset of the sliding block 300, without the need to additionally configure a reset mechanism, which not only simplifies the mold structure and reduces manufacturing cost, but also improves the reliability and response speed of the action.

[0071] The scheme further includes a driving member 600 installed on the middle frame 500, an output end of the driving member 600 being connected with the movable mold frame 100; a connecting block 340 arranged between every two adjacent sliding blocks 300, for keeping the sliding blocks 300 moving synchronously; and an inclined guide column 700 obliquely fixed on the movable mold frame 100 and penetrating through the sliding blocks 300, for guiding the oblique movement of the sliding blocks 300.

[0072] The driving member 600 is configured as a power component for moving the middle frame 500, and preferably adopts an oil cylinder. The connecting block 340 is used for realizing the synchronous movement of the plurality of sliders 300, and is preferably arranged between two adjacent sliders 300, and is fixed at one end of one slider 300 through screw connection, and is connected to the other slider 300 through plug-in mode. The inclined guide column 700 is fixed on the movable mold frame 100 and penetrates through the slider 300, and is used for guiding the slider 300 to move along a predetermined inclined path, and ensures that the core-pulling action is stable and accurate.

[0073] In the structure, the inclined guide column 700 provides accurate guidance, the connecting block 340 forcibly synchronizes, and the driving member 600 directly drives the middle frame 500, so as to realize the automatic control of the demolding process. The three cooperate with each other, and significantly improve the synchronization, movement accuracy and automation level of the mold operation, and are particularly suitable for efficient production of large and high-precision turnover baskets.

[0074] In the scheme, an injection mold for a turnover basket is also provided, which comprises the movable mold structure for a turnover basket.

[0075] In summary, the present application provides a movable mold structure and an injection mold for producing a turnover basket. Through innovative integrated design of the first forming block 200, the slider 300, the second forming block 400, the middle frame 500, the pushing block 510, the lifting block 310, the abutting block 330, the connecting block 340, the inclined guide column 700 and the driving member 600, efficient, safe and automatic demolding of large turnover baskets during injection molding is realized. The structure integrates the core (first forming block 200) and the undercut forming mechanism (second forming block 400) on the movable mold side, and drives the slider 300 to move along an inclined path by using the middle frame 500, so as to ensure that the turnover basket is internally supported by the first forming block 200 during the whole demolding process, and effectively avoids the problems of product deviation and sticking caused by premature core pulling in the traditional fixed mold core-pulling structure. Through the transmission cooperation of the pushing block 510 and the lifting block 310, the synchronous constraint of the connecting block 340, the accurate guidance of the inclined guide column 700 and the resetting function of the abutting block 330, the bidirectional linkage and accurate resetting of the slider 300 are realized, without the need for an additional resetting mechanism, which simplifies the mold structure and improves the operation stability and reliability. The scheme not only significantly improves the degree of demolding automation, solves the safety hazard of manual part taking of large turnover baskets, but also enhances the adaptability of the mold to the complex undercut structure 2.
