Description

TECHNICAL FIELD

[0001] The utility model relates to continuous mould technology field especially is related to a continuous mould of row position auxiliary demoulding. BACKGROUND

[0002] In the workpiece stamping forming process after the installation of the female die plate in the traditional continuous mould, some tricky problems are often faced. The working principle of the continuous mould is to continuously stamp the plate through the cooperation of the male die and the female die, so as to efficiently produce a large number of workpieces. However, in the actual production process, the workpiece demolding inner wall may encounter the situation of being pulled, which brings great trouble to production.

[0003] This pulling problem mainly comes from the following aspects. First, in the stamping process of the continuous mould, due to the close cooperation of the male die and the female die and the strong stamping force, the friction between the workpiece and the inner wall of the mould after forming is large. When the demolding operation is carried out, this friction is easy to cause the inner wall of the workpiece to be pulled, which affects the surface quality and dimensional accuracy of the workpiece. Secondly, for some workpieces with complex shape and special inner wall structure, the traditional demolding method is often difficult to meet the requirements. Figure 1 As shown, the workpiece with the undercut structure a or the deep cavity structure is more likely to be pulled in the demolding process.

[0004] In addition, with the continuous improvement of the quality requirements of industrial production on workpieces, the demolding method of the traditional continuous mould has been difficult to meet the production needs of high-precision and high-quality workpieces.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] Please refer to Figures 2-8In the embodiment of the present invention, a continuous mold with slide-assisted demoulding is proposed, which includes an upper mold body and a lower mold body. The lower end of the upper mold body is fixedly installed with an upper clamping plate 10, and the lower end of the upper clamping plate 10 is installed with a female template 11. The upper end of the lower mold body is installed with a lower clamping plate 20, and the upper end of the lower clamping plate 20 is installed with a male template 21. The lower end of the upper mold body is also connected to an upper stripping plate 12 surrounding the female template 11, and the upper end of the lower mold body is also connected to a male template. The lower stripper plate 22 of 21, the upper mold body and the lower mold body are movably connected with a long rod half-thread screw 30 that can move within a certain stroke. The upper stripper plate 12 is limited to the bottom of the upper mold body by the long rod half-thread screw 30, and the lower stripper plate 22 is limited to the top of the lower mold body by the long rod half-thread screw 30; the upper stripper plate 12 is also slidably connected with a sliding block 40 corresponding to the two sides of the mother template 11, and the upper splint 10 is installed with a shovel base 41 that is guided and connected to the sliding block 40.

[0033] During the stamping preparation phase, the upper and lower mold bodies are separated. The upper stripper plate 12, restrained by the long-stem, half-thread screws 30, is in its initial position below the upper mold body. The lower stripper plate 22, also restrained by the long-stem, half-thread screws 30, is in its initial position above the lower mold body. The slide blocks 40, driven by the shovel base 41 and the upper stripper plate 12, are also in their initial positions, located on either side of the mother mold plate 11.

[0034] During the stamping stage, the upper mold body moves downward, driving the upper clamping plate 10, the female mold plate 11 and the upper stripper plate 12 to move downward together. At the same time, the lower mold body remains stationary, and the male mold plate 21 and the lower stripper plate 22 also remain stationary. As the upper mold body continues to descend, the upper stripper plate 12 first contacts the workpiece or plate, playing a certain pressing role. Then, the female mold plate 11 cooperates with the male mold plate 21 to stamp the plate.

[0035] During the demoulding stage, after the stamping is completed, the upper mold body begins to move upward. At this time, the upper stripper plate 12, restricted by the long-rod half-thread screw 30, moves upward along with the upper mold body, stripping the stamped workpiece from the male mold plate 21. At the same time, the shovel base 41 installed on the upper clamping plate 10 also moves upward. The shovel base 41, through the guiding connection with the slide block 40, pushes the slide block 40 on the upper stripper plate 12 to slide toward the outside of the female mold plate 11; the sliding of the slide block 40 can assist the workpiece in demoulding from the female mold plate 11, reducing the friction between the inner wall of the workpiece and the female mold plate 11, and preventing the inner wall of the workpiece from being scratched; the lower stripper plate 22, under the elastic restoring force of the long-rod half-thread screw 30, also moves upward, pushing the waste material from the male mold plate 21.

[0036] In the above technical scheme, by arranging the row position sliding block 40 in the continuous die with row position auxiliary demolding, in the demolding process, the row position sliding block 40 slides to the outside of the female die plate 11, which can effectively reduce the friction between the inner wall of the workpiece and the female die plate 11, thereby avoiding the situation that the inner wall of the workpiece is pulled and damaged. This greatly improves the surface quality and dimensional accuracy of the workpiece, and reduces the difficulty and cost of subsequent processing;

[0037] The upper stripper plate 12 and the lower stripper plate 22 of the die can quickly and accurately perform the pressing and demolding operation under the limitation of the long rod half tooth screw 30. At the same time, the sliding auxiliary demolding of the row position sliding block 40 also makes the demolding process more smooth and efficient, thereby improving the production efficiency of the whole continuous die;

[0038] For workpieces of different shapes and sizes, especially workpieces with complex shapes such as reverse clamping structure or deep cavity structure, the continuous die with row position auxiliary demolding can adapt to different demolding requirements by adjusting the position and sliding stroke of the row position sliding block 40, and has strong applicability;

[0039] The use of the long rod half tooth screw 30 can not only limit the movement range of the upper stripper plate 12 and the lower stripper plate 22, but also provide a certain elastic restoring force, thereby ensuring the stability and reliability of the die in the working process. At the same time, the guide connection structure of the shovel base 41 and the row position sliding block 40 also makes the movement of the row position sliding block 40 more accurate and stable.

[0040] Please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 In the embodiment of the utility model, further propose that the upper die main body includes upper supporting plate 13, upper pad 14 installed at the lower end of upper supporting plate 13 and upper die seat 15 installed at the lower end of upper pad 14, upper clamping plate 10 is installed at the lower end of upper die seat 15, and upper accommodating hole 16 accommodating the end of long rod half tooth screw 30 is formed on upper die seat 15, and upper limiting through hole for passing long rod half tooth screw 30 and limiting the end of long rod half tooth screw 30 is formed on upper clamping plate 10;The lower die main body includes lower pad 23 and lower die seat 24 installed on lower pad 23, and lower clamping plate 20 is installed on lower die seat 24, lower accommodating hole 26 accommodating the end of long rod half tooth screw 30 is formed on lower die seat 24, and lower limiting through hole for passing long rod half tooth screw 30 and limiting the end of long rod half tooth screw 30 is formed on lower clamping plate 20.

[0041] The upper supporting plate 13 is the top supporting structure of the upper die body, bears the pressure from the stamping equipment and transmits it to the upper cushion block 14 and the upper die seat 15; when the stamping process starts, the upper die seat 15 drives the upper clamping plate 10, the female die plate 11 and the upper stripper plate 12 to move downward. The end of the long rod half-dog screw 30 is movable within a certain range in the upper accommodating hole 16 of the upper die seat 15; the upper limiting through hole on the upper clamping plate 10 limits the long rod half-dog screw 30, so that the long rod half-dog screw 30 does not displace laterally when moving with the upper die seat 15, ensuring the stability of the movement. The lower cushion block 23 provides support and buffering for the lower die seat 24; after the stamping is completed, the upper die body moves upward, the lower die seat 24 remains relatively stable under the elastic restoring force of the long rod half-dog screw 30, and the lower clamping plate 20 and the male die plate 21 also remain stationary; the end of the long rod half-dog screw 30 is movable in the lower accommodating hole 26 of the lower die seat 24, and the lower limiting through hole on the lower clamping plate 20 limits the end of the long rod half-dog screw 30, ensuring the correct position of the long rod half-dog screw 30 during the demolding process.

[0042] Therefore, by further setting the structure of the upper die body and the lower die body, the combination of the upper supporting plate 13, the upper cushion block 14 and the upper die seat 15, and the combination of the lower cushion block 23 and the lower die seat 24, a more stable structural support is provided for the die, which can withstand a larger stamping force without deforming during the stamping process, ensuring the precision and service life of the die; the cooperation of the long rod half-dog screw 30 with the upper accommodating hole 16, the upper limiting through hole, and the lower accommodating hole 26, the lower limiting through hole further enhances the stability of the die during the movement process, reducing the errors caused by vibration or displacement; the upper accommodating hole 16 and the upper limiting through hole, the lower accommodating hole 26 and the lower limiting through hole limit the long rod half-dog screw 30 of the upper die body and the lower die body respectively, which can accurately control the movement stroke of the upper stripper plate 12 and the lower stripper plate 22, making the die more accurate and reliable during stamping and demolding, improving the quality of the workpiece and the production efficiency; this structure design makes the connection between the various components of the die clearer and more explicit, facilitating installation and disassembly, and when the die fails or needs maintenance, the problem can be quickly located and repaired, reducing maintenance cost and time.

[0043] Please refer to Figures 2-5 In the embodiment of the utility model, further propose that the long rod half-dog screw 30 has a cup head 31, a threaded long rod 32 integrally formed on the cup head 31, and an external thread 33 arranged at the end of the threaded long rod 32 for threadedly connecting the upper stripper plate 12 or the lower stripper plate 22, a limiting sleeve 34 abutting against the cup head 31 is fixedly sleeved on the threaded long rod 32, a flange part 35 is arranged at the end of the limiting sleeve 34, the long rod half-dog screw 30 corresponding to the upper die body is limited by abutting against the upper accommodating hole 16 through the flange part 35, and the long rod half-dog screw 30 corresponding to the lower die body is limited by abutting against the lower accommodating hole 26 through the flange part 35.

[0044] In the process of assembling the mold, the threaded shank 32 of the long shank half tooth screw 30 is sequentially threaded through the upper clamp plate 10 and the upper die seat 15 of the upper mold body, or the lower clamp plate 20 and the lower die seat 24 of the lower mold body, the limiting sleeve 34 is fixedly sleeved on the threaded shank 32, and the flange portion 35 is close to one side of the cup head portion 31; for the upper mold body, the flange portion 35 of the long shank half tooth screw 30 abuts against the upper accommodating hole 16 to limit, preventing the long shank half tooth screw 30 from moving upward excessively, and for the lower mold body, the flange portion 35 abuts against the lower accommodating hole 26 to limit, preventing the long shank half tooth screw 30 from moving downward excessively; in the process of stamping, the upper mold body moves downward, the long shank half tooth screw 30 moves upward accordingly, the distance between the cup head portion 31 and the upper die seat 15 or the lower die seat 24 gradually decreases, at this time, the flange portion 35 of the limiting sleeve 34 keeps abutting against the upper accommodating hole 16 or the lower accommodating hole 26; when entering the demolding stage, the upper mold body moves upward, the long shank half tooth screw 30 moves downward under the action of the elastic restoring force, pushes the upper stripper plate 12 or the lower stripper plate 22 to push the workpiece or waste out of the mold, and the flange portion 35 of the limiting sleeve 34 continues to play a limiting role, preventing the long shank half tooth screw 30 from moving downward excessively. Through the abutting limiting of the flange portion 35 of the limiting sleeve 34 and the upper accommodating hole 16 or the lower accommodating hole 26, the position of the long shank half tooth screw 30 in the mold can be accurately controlled, ensuring that the movement stroke of the upper stripper plate 12 and the lower stripper plate 22 in the stamping and demolding processes is accurate and correct, which helps to improve the dimensional accuracy and quality stability of the workpiece; the long shank half tooth screw 30 bears a large force in the working process of the mold, the setting of the limiting sleeve 34 can increase the stability of the screw, the flange portion 35 can be limited in the accommodating hole, so that the upper stripper plate 12 or the lower stripper plate 22 can only be separated by a certain distance; the fixed sleeving mode of the limiting sleeve 34 makes the installation of the long shank half tooth screw 30 more convenient and fast, at the same time, if it is necessary to adjust the position or stroke of the long shank half tooth screw 30, it can be realized by replacing the limiting sleeve 34 with different thickness, which has high flexibility and operability; accurate limiting and stable structure can reduce the wear and damage of the mold in the working process, prolong the service life of the mold, and reduce the production cost.

[0045] Please refer to Figures 2-5The utility model discloses further propose in the cup head 31 on the sleeve setting spring 36, install fixed block 37 in the upper accommodating hole 16 and lower accommodating hole 26, spring 36 abuts between flange portion 35 and fixed block 37. When the upper die body moves downward and carries out stamping, long rod half tooth screw 30 moves upward along with the movement of the upper die body, at this time, spring 36 on the cup head 31 is compressed, and one end of spring 36 abuts on flange portion 35, and the other end abuts on fixed block 37. For the lower die body, during the stamping process, the lower die body is relatively stationary, but long rod half tooth screw 30 will also be subjected to certain pressure, so that spring 36 is in the compression or pre-tightening state. After stamping is completed, the upper die body moves upward and carries out stripping, at this time, spring 36 starts to release elastic potential energy, and pushes long rod half tooth screw 30 to move downward, and long rod half tooth screw 30 drives upper stripping plate 12 to peel off the workpiece from female die plate 11, and meanwhile, lower stripping plate 22 also pushes the waste material out of male die plate 21 under the action of spring 36.

[0046] Through the setting, the setting of spring 36 provides additional elastic force for upper stripping plate 12 and lower stripping plate 22, so that the stripping process is more smooth. During stripping, the elastic force of spring 36 can help to overcome the friction force between the workpiece and the die, effectively prevents the workpiece inner wall from being scratched, and improves the stripping efficiency and workpiece quality. During the stamping process, spring 36 can play a buffering role, and reduces the impact force between the upper die body and the lower die body. This helps to protect the various components of the die and prolong the service life of the die. Spring 36 abuts between flange portion 35 and fixed block 37, can limit the movement range of long rod half tooth screw 30, and ensure that the screw does not displace excessively during the working process of the die, which helps to improve the movement stability and precision of the die.

[0047] Please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 The utility model discloses further propose that the upper end of upper clamping plate 10 still is equipped with stop plate 17, and stop plate 17 is fixedly installed at the lower end of upper die body. The installation of stop plate 17 increases the structural strength and stability of the upper die part. When bearing the stamping force, the deformation and vibration of the upper die body can be effectively reduced, and the overall performance and service life of the die are improved.

[0048] Please refer to Figures 6-8 The utility model discloses further propose that the guide inclined hole 42 is seted up on the line position sliding block 40, and the spade base 41 is fixedly connected to the upper clamping plate 10, and the spade base 41 and the guide inclined hole 42 slide fit. Through the slide fit of guide inclined hole 42 and spade base 41, the movement direction and stroke of line position sliding block 40 can be accurately controlled. During the stripping process, it can be ensured that line position sliding block 40 slides according to the predetermined trajectory, accurately assists the stripping of the workpiece, and improves the reliability and stability of stripping.

[0049] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments, but that the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments should, therefore, be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
