AI Technical Summary
[0003]基于上述，本发明人发现存在以下问题：现在的五金模具在使用过程中，由于冲压时顶模具与冲压件外壁紧密贴合，开模时若冲压件带翻边或卡扣等结构，容易嵌合在顶模具内部，导致冲压件随顶模具上升，无法自然脱落，操作人员需用镊子夹取或工具撬动才能取出冲压件，耗时长，同时工具撬动会损伤顶模具内壁
[0009]采用上述进一步方案的有益效果是，开模时负压泵启动，向支座外部抽气，通过连通管将吸力依次传递至连通腔、连通座，最终经第一顶孔、第一侧孔作用于冲压件，可使冲压件紧贴底模具内壁，避免冲压后顶模具上移导致冲压件随顶模具一同移动；当顶模座恢复原位后负压泵停止工作不再向支座外部抽气，连通管与连通腔形成的密闭通路快速泄压，吸附力瞬间消失，而后在顶升组件的作用下将冲压件与顶模具分离。

Description
Technical Field
[0001] This utility model relates to the field of hardware mold technology, specifically a hardware mold with a quick demolding structure. Background Technology
[0002] As core equipment in the hardware processing industry, metal molds play a crucial role in stamping metal sheets into specific shapes (such as electronic component housings, precision automotive parts, and household appliance hardware). Through cylinders or hydraulic pressure, the top mold base descends to close the mold, stamping the metal sheet into a pre-set shape. After mold closure, the top mold base rises to open the mold, and the stamped part is then manually removed by the operator. Metal molds can be classified according to their process characteristics into blanking dies, bending dies, drawing dies, and forming dies.
[0003] Based on the above, the inventors have discovered the following problems: In the current use of hardware molds, because the top mold is tightly fitted to the outer wall of the stamped part during stamping, if the stamped part has a flange or buckle structure, it is easy to get stuck inside the top mold when the mold is opened. This causes the stamped part to rise with the top mold and cannot fall off naturally. Operators need to use tweezers or tools to pry it out, which is time-consuming. At the same time, prying with tools will damage the inner wall of the top mold.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a hardware mold with a quick demolding structure in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this utility model is to provide a hardware mold with a quick demolding structure to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A hardware mold with a rapid demolding structure includes a mold assembly, an adsorption assembly, and a lifting assembly. The mold assembly includes a bottom mold base, with a top mold base at its upper end. A first circular hole is located at the center of the bottom mold base, and a second circular hole is located at the center of the top mold base. A bottom mold is installed in the first circular hole, and a top mold is installed in the second circular hole. The bottom mold has a plurality of first top holes circumferentially arranged on its inner bottom surface, and a plurality of first side holes circumferentially arranged on its outer wall. An installation cavity is formed inside the bottom mold. The adsorption assembly includes a connecting seat and a support. The connecting seat is installed in the installation cavity, with a plurality of second top holes circumferentially arranged on its top surface and a plurality of second side holes circumferentially arranged on its outer wall. The support is installed on the bottom surface of the bottom mold, and a connecting cavity is formed inside the support. A negative pressure pump is installed on the outer wall of the support.
[0008] Furthermore, a connecting pipe is installed inside the connecting cavity, the air outlet of the connecting pipe passes through the connecting seat and extends into the connecting seat, and the air inlet of the negative pressure pump passes through the air inlet of the connecting pipe and extends into the air inlet.
[0009] The beneficial effect of adopting the above-mentioned further solution is that when the mold is opened, the negative pressure pump starts and draws air to the outside of the support. The suction force is transmitted to the connecting cavity and the connecting seat in sequence through the connecting pipe, and finally acts on the stamping part through the first top hole and the first side hole. This can make the stamping part stick tightly to the inner wall of the bottom mold, and prevent the stamping part from moving with the top mold after stamping. When the top mold seat returns to its original position, the negative pressure pump stops working and no longer draws air to the outside of the support. The closed passage formed by the connecting pipe and the connecting cavity is quickly depressurized, and the suction force disappears instantly. Then, under the action of the lifting component, the stamping part is separated from the top mold.
[0010] Furthermore, a number of the first top holes are aligned with a number of the second top holes, and a number of the first side holes are aligned with a number of the second side holes.
[0011] The beneficial effects of adopting the above-mentioned further solution are that the first top hole and the second top hole are aligned one by one, which can adsorb the central area of the bottom surface of the stamped part; the first side hole and the second side hole are aligned one by one, which can adsorb the side wall area of the stamped part; during demolding, the pressure relief airflow can flow quickly through the aligned holes.
[0012] Furthermore, grooves are provided on both sides of the outer wall of the bottom mold base, and cylinders are installed inside the two grooves. The telescopic ends of the two cylinders are fixedly connected to the two sides of the bottom surface of the top mold base, respectively.
[0013] The beneficial effects of adopting the above-mentioned further solution are that the groove facilitates the installation of the cylinder; when the cylinder is started, its telescopic end can drive the top mold base to move stably in the vertical direction; when the mold is closed, the cylinder retracts and drives the top mold base to descend, so that the top mold and the bottom mold are precisely fitted; when the mold is opened, the cylinder extends and drives the top mold base to rise, quickly separating from the bottom mold base, leaving sufficient space for subsequent demolding operations.
[0014] Furthermore, the lifting assembly includes a base plate, the top surface of which is in contact with the bottom surface of the support. Electric slide rails are installed on both sides of the top surface of the base plate. Electric sliders are slidably connected to the outside of the two electric slide rails. Push blocks are installed on the top surfaces of the two electric sliders. Lifting blocks are provided on one side of the two push blocks. The top surfaces of the two lifting blocks are fixedly connected to the two sides of the bottom surface of the bottom mold base. The two electric slide rails drive the two electric sliders to move in the same direction and at the same speed.
[0015] The beneficial effect of adopting the above-mentioned further solution is that when the electric slide rail is activated, it drives the electric slider to slide the push block in the horizontal direction. The push block, in cooperation with the lifting block, converts the horizontal movement into a vertical lifting force. When the push block moves towards the lifting block, the lifting block, under the pushing force of the push block, drives the bottom mold base to rise, so that the bottom mold is separated from the stamped part, which facilitates material removal and demolding. Through the overall lifting of the bottom mold base, the stamped part is subjected to uniform force, avoiding deformation of the hardware caused by local force.
[0016] Furthermore, both the push block and the lifting block are trapezoidal, and the opposite sides of the push block and the lifting block are inclined. The opposite sides of the push block and the lifting block are in contact with each other. The lifting block has a groove on the side near the push block. A slider is provided inside the groove. One side of the slider is fixedly connected to the inclined side of the push block. The outer wall of the slider slides in cooperation with the inner wall of the groove.
[0017] The beneficial effects of adopting the above-mentioned further solution are that the inclined surfaces of the push block and the lifting block can transmit a larger lifting force, and the sliding cooperation of the inclined surfaces can efficiently convert the horizontal thrust into the vertical lifting force; the sliding cooperation of the slider and the slide groove provides directional guidance for the lifting block, prevents the bottom mold base from shifting during the lifting process, and ensures that the bottom mold and the top mold always keep their center lines aligned.
[0018] Furthermore, the bottom mold has a stamped part on its outer wall at the end away from the bottom plate. The inner wall of the stamped part is in contact with the outer wall of the bottom mold at the end away from the bottom plate, and the outer wall of the stamped part is in contact with the inner wall of the top mold.
[0019] The beneficial effect of adopting the above-mentioned further solution is that when the top mold base and the bottom mold base are closed, the metal sheet is stamped into a matching stamped part under the cooperation of the top mold and the bottom mold (the inner wall of the stamped part is in contact with the outer wall of one end of the bottom mold, and the outer wall of the stamped part is in contact with the inner wall of the top mold).
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This hardware mold with a quick demolding structure, when the top mold base and bottom mold base are closed, stamps the metal sheet into a matching stamped part under the cooperation of the top and bottom molds; when the mold opens, the negative pressure pump starts, drawing air out of the support, and the suction force is sequentially transmitted to the connecting cavity and connecting seat through the connecting pipe, finally acting on the stamped part through the first top hole and the first side hole, which can make the stamped part tightly adhere to the inner wall of the bottom mold, preventing the stamped part from moving with the top mold after stamping; when the top mold base returns to its original position, the negative pressure pump stops working and no longer draws air out of the support, and the connecting pipe and connecting cavity... The formed closed passage quickly releases pressure, and the adsorption force disappears instantly. Then, under the action of the lifting component, the stamped part is separated from the top mold. The electric slide rail is activated, which drives the electric slider to move the push block horizontally. The push block, in cooperation with the lifting block, converts the horizontal movement into a vertical lifting force. When the push block moves towards the lifting block, the lifting block, under the pushing force of the push block, drives the bottom mold base to rise, separating the bottom mold from the stamped part, facilitating material removal and demolding. Through the overall lifting of the bottom mold base, the stamped part is subjected to uniform force, avoiding deformation of the hardware caused by localized force; effectively preventing the stamped part from being embedded inside the top mold, which would cause demolding difficulties.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5 This utility model provides a technical solution: a hardware mold with a quick demolding structure, including a mold assembly 1, an adsorption assembly 2, and a lifting assembly 3. The mold assembly 1 includes a bottom mold base 11, a top mold base 12 is provided at the upper end of the bottom mold base 11, a first circular hole is provided at the center of the bottom mold base 11, and a second circular hole is provided at the center of the top mold base 12. A bottom mold 15 is installed in the first circular hole, and a top mold 14 is installed in the second circular hole. The bottom surface of the bottom mold 15 has a plurality of first top holes 17 arranged circumferentially, and the outer wall of the bottom mold 15 has a plurality of first side holes 16 arranged circumferentially. An installation cavity is opened inside the bottom mold 15. The adsorption assembly 2 includes a connecting seat 21 and a support 24. The connecting seat 21 is installed in the installation cavity. The top surface of the connecting seat 21 has a plurality of second top holes 23 arranged circumferentially, and the outer wall of the connecting seat 21 has a plurality of second side holes 22 arranged circumferentially. The support 24 is installed on the bottom surface of the bottom mold 15. An internal connecting cavity is provided. A negative pressure pump 26 is installed on the outer wall of the support 24. A connecting pipe 25 is installed inside the connecting cavity. The air outlet of the connecting pipe 25 passes through the connecting seat 21 and extends into the interior of the connecting seat 21. The air inlet of the negative pressure pump 26 passes through the air inlet of the connecting pipe 25 and extends into the interior of the air inlet. Several first top holes 17 are respectively aligned with several second top holes 23, and several first side holes 16 are respectively aligned with several second side holes 22. The electric slide rail 32 is activated. The electric slider 33 drives the push block 34 to slide horizontally. The push block 34, in cooperation with the lifting block 35, converts the horizontal movement into a vertical lifting force. When the push block 34 moves toward the lifting block 35, the lifting block 35, under the pushing force of the push block 34, drives the bottom mold base 11 to rise, so that the bottom mold 15 is separated from the stamping part 4, making it easier to remove the material and demold. By lifting the bottom mold base 11 as a whole, the stamping part 4 is subjected to uniform force, avoiding deformation of the hardware caused by local force.
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-5 This utility model provides a technical solution: Grooves are provided on both sides of the outer wall of the bottom mold base 11. Cylinders 13 are installed inside each of the two grooves. The telescopic ends of the two cylinders 13 are fixedly connected to both sides of the bottom surface of the top mold base 12. The lifting assembly 3 includes a base plate 31, the top surface of which is in contact with the bottom surface of the support 24. Electric slide rails 32 are installed on both sides of the top surface of the base plate 31. Electric sliders 33 are slidably connected to the outside of each of the two electric slide rails 32. Push blocks 34 are installed on the top surfaces of each of the two electric sliders 33. Each side of the push block 34 is provided with a lifting block 35. The top surfaces of the two lifting blocks 35 are fixedly connected to the two sides of the bottom surface of the bottom mold base 11, respectively. Both the push block 34 and the lifting block 35 are trapezoidal, and the opposite sides of the push block 34 and the lifting block 35 are inclined, and the opposite sides of the push block 34 and the lifting block 35 are in contact with each other. A sliding groove is opened on the side of the lifting block 35 near the push block 34. A slider is provided inside the sliding groove. One side of the slider is fixedly connected to the inclined side of the push block 34. The outer wall of the slider slides in cooperation with the inner wall of the sliding groove. A stamped part 4 is provided on the outer wall of the bottom mold 15 at the end away from the base plate 31. The inner wall of the stamped part 4 fits against the outer wall of the bottom mold 15 at the end away from the base plate 31, and the outer wall of the stamped part 4 fits against the inner wall of the top mold 14. When the cylinder 13 is activated, its telescopic end can drive the top mold base 12 to move stably in the vertical direction. When the mold is closed, the cylinder 13 retracts and drives the top mold base 12 to descend, so that the top mold 14 and the bottom mold 15 fit precisely. When the mold is opened, the cylinder 13 extends and drives the top mold base 12 to rise, quickly separating from the bottom mold base 11, so as to prepare for subsequent... Sufficient space is reserved for demolding operation; the electric slide rail 32 is activated, which drives the electric slider 33 to move the push block 34 horizontally. The push block 34, in cooperation with the lifting block 35, converts the horizontal movement into a vertical lifting force. When the push block 34 moves toward the lifting block 35, the lifting block 35, under the pushing force of the push block 34, drives the bottom mold base 11 to rise, so that the bottom mold 15 is separated from the stamped part 4, which facilitates material removal and demolding. The overall lifting of the bottom mold base 11 makes the stamped part 4 evenly stressed, avoiding deformation of the hardware caused by local stress.
[0031] Specifically, the working principle of this type of hardware mold with a quick demolding structure is as follows: During use, the metal sheet is placed on the bottom mold 15; the cylinder 13 is activated, and its telescopic end drives the top mold base 12 to move stably in the vertical direction. When the mold closes, the cylinder 13 retracts, causing the top mold base 12 to descend, so that the top mold 14 and the bottom mold 15 precisely fit together. The metal sheet is stamped into a matching stamped part 4 under the cooperation of the top mold 14 and the bottom mold 15. Simultaneously, when the mold opens, the negative pressure pump 26 is activated to draw air out of the support 24. The suction force is transmitted sequentially to the connecting cavity and the connecting seat 21 through the connecting pipe 25, and finally acts on the stamped part 4 through the first top hole 17 and the first side hole 16, ensuring that the stamped part 4 fits tightly against the inner wall of the bottom mold 15, preventing the top mold 14 from moving upwards after stamping and causing the stamped part 4 to move with the top mold 14. When the cylinder 13 extends, it drives... The top mold base 12 rises and quickly separates from the bottom mold base 11. After the top mold base 12 returns to its original position, the negative pressure pump 26 stops working and no longer draws air out of the support 24. The closed passage formed by the connecting pipe 25 and the connecting cavity quickly releases pressure, and the adsorption force disappears instantly. Then, under the action of the lifting component 3, the stamping part 4 is separated from the top mold 14. The electric slide rail 32 is activated, which drives the electric slider 33 to drive the push block 34 to slide in the horizontal direction. The push block 34, through cooperation with the lifting block 35, converts the horizontal movement into a vertical lifting force. When the push block 34 moves towards the lifting block 35, the lifting block 35 drives the bottom mold base 11 to rise under the pushing force of the push block 34, so that the bottom mold 15 is separated from the stamping part 4, which facilitates material removal and demolding. Through the overall lifting of the bottom mold base 11, the stamping part 4 is subjected to uniform force, avoiding deformation of the hardware caused by local force.
