Description

Technical Field

[0001] This utility model is a quick demolding device for mold manufacturing, belonging to the field of mold manufacturing. Background Technology

[0002] Although molds are not conspicuous in people's lives, their influence can be felt everywhere. From large casting molds for car parts to small molds used to make ice cubes in refrigerators, molds play an irreplaceable role in manufacturing. Moreover, incomplete demolding often leads to mold breakage or scrap due to the complexity of the demolding process, which requires a significant investment of manpower and is time-consuming and labor-intensive.

[0003] Chinese patent CN220499679U proposes a rapid demolding device for mold manufacturing. The device uses a rotary controller to control the entire mold making and demolding process. However, uneven stress on the mold during demolding leads to mold damage, and the manual rotary controller results in poor demolding efficiency. There is an urgent need for a rapid demolding device for mold manufacturing to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a rapid demolding device for mold manufacturing, thereby solving the problems mentioned in the background section. This invention has a reasonable structure and solves the above problems by setting up several sleeve rods, each sleeve rod containing a spring. The sleeve rods are distributed in a rectangular plane, and the spring force generated when the hydraulic telescopic rod extends upward causes the cooled model to separate from the mold. This greatly reduces the problem of model damage and has high demolding efficiency.

[0005] To achieve the above objectives, this utility model provides a rapid demolding device for mold manufacturing, comprising a machine body, a control panel, a demolding device, and a storage bin. The control panel is mounted on the top of the machine body, the demolding device is mounted on the left side of the control panel, and the storage bin is mounted on the upper part of the control panel. The demolding device includes a material bin, a base, a lower mold, a hydraulic telescopic mechanism, an upper mold, and a connecting seat. The base is mounted on the upper surface of the machine body, the material bin is connected below the base, and the connecting seat is mounted on the upper part of the base. A hydraulic telescopic mechanism is installed inside the base, the lower mold is positioned above the connecting seat, and the upper mold is positioned above the lower mold.

[0006] Furthermore, the upper mold has a groove inside, the groove having the same shape and size as the outer surface of the lower mold, and a mold groove inside the groove having the same shape and size as the inner surface of the lower mold.

[0007] Furthermore, several positioning seats are provided at the four corners of the base, and several sets of hydraulic telescopic machines are installed inside the several sets of positioning seats. Hydraulic telescopic rods are connected to the upper ends of the several sets of hydraulic telescopic machines, and the upper ends of the hydraulic telescopic rods are welded to the upper mold.

[0008] Furthermore, the connector has mounting slots at its four corners, a first sleeve rod inside the mounting slot, a first spring inside the first sleeve rod, a first connecting post above the first spring, and the first connecting post is welded to the bottom of the lower mold.

[0009] Furthermore, a mounting base is provided at the center of the connecting seat, and a plurality of second sleeve rods are provided inside the mounting base. A second spring is provided inside the second sleeve rods, and a second connecting post is connected above the second spring.

[0010] Furthermore, the lower mold has several sets of positioning grooves inside, each positioning groove corresponding to a second connecting post. The upper end face of the several sets of second connecting posts is on the same plane as the lower end face of the positioning groove. The lower mold is connected to a grouting port on the outside.

[0011] The beneficial effects of this utility model: This utility model provides a quick demolding device for mold manufacturing. Because it includes a control panel, a hydraulic telescopic mechanism, a telescopic sleeve rod, a hydraulic telescopic rod, an upper mold, a lower mold, a first sleeve rod, a first spring, a first connecting rod, a second sleeve rod, a second spring, and a second connecting rod, the user can control the extension and retraction of the hydraulic telescopic rod of the hydraulic telescopic mechanism via the control panel to control the rising and falling of the upper mold for mold making. When the upper mold falls, mold making begins; the first and second connecting rods fall, causing the first and second springs to undergo elastic deformation. Once the mold has cooled, the upper mold rises to begin demolding, and the elastic deformation of the springs separates the mold from the lower mold. This design solves problems such as mold damage during demolding leading to mold scrap and poor demolding efficiency. This product is simple, convenient, and highly practical.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-6 This utility model provides a technical solution: a rapid demolding device for mold manufacturing, including a machine body 1, a control panel 2, a demolding device 4, and a storage tank 5. The control panel 2 is installed on the top of the machine body 1, the demolding device 4 is installed on the left end of the control panel 2, and the storage tank 5 is installed on the upper end of the control panel 2. The demolding device 4 includes a material box 3, a base 6, a connecting seat 10, a lower mold 9, a hydraulic telescopic mechanism 8, an upper mold 7, and the connecting seat 10. The material box 3 is connected to the lower part of the base 6, the connecting seat 10 is installed on the upper end of the base 6, the hydraulic telescopic mechanism 8 is installed inside the base 6, the lower mold 9 is installed above the connecting seat 10, and the upper mold 7 is installed above the lower mold 9.

[0022] As the first embodiment of this utility model: A groove 71 is provided inside the upper mold 7. The groove 71 has the same shape and size as the lower mold 9 and a smooth inner wall, allowing the upper mold 7 to engage with the lower mold 9 when pressing down. A mold groove 72 is provided inside the groove 71. The mold groove 72 has the same shape and size as the lower mold 9, similarly allowing it to engage with the lower mold 9. Several sets of positioning seats 41 are provided at the four corners of the base 6. Several hydraulic telescopic mechanisms 8 are installed inside the several sets of positioning seats 41. The upper part of the hydraulic telescopic mechanisms 8 is the output end. A hydraulic telescopic rod 82 is connected to the upper end of the several hydraulic telescopic mechanisms 8. The upper end of the hydraulic telescopic rod 82 is welded to the upper mold. The extension and retraction of the hydraulic telescopic rod 82 controls the rising and falling of the upper mold 7. An installation groove 101 is provided at the four corners inside the connecting seat 10. A first set of rods 11 is provided inside the installation groove 101. A first spring 111 is installed inside a set of rods 11. A first connecting post 112 is connected above the first spring 111. The first connecting post 112 is welded to the bottom of the lower mold 9. When the upper mold is pressed down, causing the lower mold 9 to move downward, the first spring 111 undergoes elastic deformation. A mounting seat 102 is provided at the center of the connecting seat 10. Several second rods 12 are installed inside the mounting seat 102. Second springs 122 are installed inside the second rods 12. A second connecting post 121 is connected above the second springs 122. Several positioning grooves 91 are opened inside the lower mold 9. The positioning grooves 91 correspond one-to-one with the second connecting posts 121. The upper end face of the second connecting posts 121 is on the same plane as the lower end face of the positioning grooves 91. Similarly, when the lower mold 9 is pressed down, the second spring 122 undergoes elastic deformation. A grouting port 92 is connected to the outside of the lower mold 9 to facilitate grouting during mold making.

[0023] As a second embodiment of this utility model: When using this new model for mold making, the user can pour the mold making material into the injection port 92, and then control the control panel 2 to operate the hydraulic telescopic rod 82 of the hydraulic telescopic machine 8 to retract. The upper mold 7 connected to the hydraulic telescopic rod 82 moves downward in the vertical direction until the model groove inside the groove 71 of the upper mold 7 engages with the lower mold 9. At this time, because the lower mold 9 moves downward under the pressure of the upper mold 7, the first connecting rod and the second connecting rod move downward, and the first spring 111 and the second spring 122 contract and undergo elastic deformation. When the model has cooled down, the user can control the control panel 2 to extend the hydraulic telescopic rod 82, and the upper mold 7 moves in the vertical direction. The model groove separates from the lower mold 9. The first spring 111, because its height is higher than the second spring 122, begins to elastically deform first, accelerating the upward movement of the lower mold 9. The second spring 122 begins to elastically deform, causing the second connecting rod to generate an upward elastic force, causing the model to separate from the lower mold 9. By taking out the release agent from the storage box 5 and putting it into the lower mold 9, the model can be better removed.
