Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a mold structure with a locking mechanism. Background Technology

[0002] Molds are an indispensable basic process device in industrial production. Their main function is to process metal or non-metal materials into parts of specific shapes by changing pressure or physical state. By making molds of suitable styles, the production cost of some complex parts can be reduced. At the same time, molds can often be reused, thus saving certain costs.

[0003] During the processing of parts using molds, it is sometimes necessary to shake the mold to ensure that the solution inside the mold is fully filled. However, traditional molds are often fixed with bolts, which can easily loosen when subjected to external influences, thus affecting the mold's sealing performance. To solve this problem, there is an urgent need for a mold structure with a locking mechanism. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that during the processing of parts through a mold, it is sometimes necessary to shake the mold to ensure that the solution inside the mold is fully filled. However, since traditional molds are often fixed with bolts, the bolts are prone to loosening when subjected to external influences, thus affecting the sealing of the mold. Therefore, a mold structure with a locking mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold structure with a locking mechanism, including a lower mold, a skirt fixedly installed on the top surface of the lower mold, a sealing strip fixedly installed on the top surface of the skirt, a sealing component provided on the top surface of the skirt, and an adjustment component provided inside the sealing component;

[0006] The sealing assembly includes a mounting plate, on both sides of which mounting frames are fixedly mounted. Hooks are slidably mounted on the mounting frames through grooves opened therein. A connecting rod is fixedly mounted on the top of the hooks. A first spring is fixedly mounted on one side of the hooks. A sliding rod is slidably mounted on the mounting plate through a through hole opened therein. A cover plate is fixedly mounted on the bottom of the sliding rod. A second spring is provided on the outer wall of the sliding rod.

[0007] As a further description of the above technical solution:

[0008] The other end of the first spring is fixedly connected to the mounting frame, and the cover plate has openings on both sides corresponding to the hook claws.

[0009] As a further description of the above technical solution:

[0010] The second spring is located between the mounting plate and the cover plate, and the bottom surface of the cover plate is provided with a groove corresponding to the sealing strip.

[0011] As a further description of the above technical solution:

[0012] The skirt has grooves on both sides corresponding to the hook claws, and the bottom end of the second spring is fixedly connected to the cover plate.

[0013] As a further description of the above technical solution:

[0014] The adjustment assembly includes an airbag, a fixing plate is fixedly installed on the top surface of the airbag, an air inlet check valve is fixedly installed on the top surface of the fixing plate, and an air outlet check valve is fixedly installed on the top surface of the fixing plate.

[0015] As a further description of the above technical solution:

[0016] The top of the air inlet check valve and the air outlet check valve are fixedly installed with mounting sleeves. A sealing plate is slidably installed on the mounting sleeve through a groove opened inside it. An air tube is fixedly installed at the bottom of the airbag, and a baffle is slidably installed inside the air tube.

[0017] As a further description of the above technical solution:

[0018] A round rod is fixedly installed on the top surface of the baffle. The top end of the round rod is fixedly connected to the fixing plate. The top surface of the fixing plate is fixedly connected to the mounting plate. The airbag is located between the mounting plate and the cover plate.

[0019] As a further description of the above technical solution:

[0020] Both the inlet check valve and the outlet check valve are fixedly connected to the mounting plate through through holes in the mounting plate, and the air pipe is fixedly connected to the mounting plate through through holes in the cover plate.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by providing hooks inside, when sealing the lower mold, pulling the connecting rod drives the hooks to move to both sides, further compressing the first spring. At the same time, the cover plate is placed on the top surface of the lower mold and fits against the skirt. Simultaneously, pressing down the mounting plate drives the hooks downward, causing them to hook into the grooves on both sides of the skirt. Through this design, when sealing the mold, the hooks can hook onto the skirt on the top surface of the lower mold, and the compression of the cover plate by the second spring ensures that the cover plate is tightly connected to the lower mold. This prevents the cover plate from loosening during processing and affecting the sealing performance of the mold. Furthermore, since the hooks are located in the grooves of the skirt, they can limit the cover plate, thus preventing the cover plate from shifting.

[0023] 2. In this utility model, by incorporating an airbag, when the mounting plate is pressed, the inlet one-way valve is first blocked by the sliding sealing plate, thereby compressing the airbag when the mounting plate is pressed. The round rod drives the baffle to move downward, thus clearing the air pipe. Simultaneously, due to the compression of the airbag, gas can be discharged outward from the outlet one-way valve. When the hook is connected to the skirt and the mounting plate is moved upward by the second spring, the airbag expands and draws the gas in the lower mold into the airbag through the air pipe. As the mounting plate moves upward, the round rod drives the baffle to move upward, thus blocking the air pipe. Through this design, when sealing the lower mold, a portion of the gas in the lower mold can be drawn out by the airbag, thereby reducing the air content in the lower mold, reducing the air pressure in the lower mold, and further ensuring the sealing performance of the mold.

Detailed Implementation

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a mold structure with a locking mechanism, including a lower mold 1, a skirt 2 fixedly installed on the top surface of the lower mold 1, a sealing strip 3 fixedly installed on the top surface of the skirt 2, a sealing component 4 provided on the top surface of the skirt 2, and an adjustment component 5 provided inside the sealing component 4;

[0032] The sealing assembly 4 includes a mounting plate 41, on both sides of which mounting frames 42 are fixedly mounted. Hooks 44 are slidably mounted on the mounting frames 42 through grooves opened therein. A connecting rod 45 is fixedly mounted on the top of the hooks 44. A first spring 43 is fixedly mounted on one side of the hooks 44. A sliding rod 46 is slidably mounted on the mounting plate 41 through a through hole opened therein. A cover plate 48 is fixedly mounted on the bottom of the sliding rod 46. A second spring 47 is provided on the outer wall of the sliding rod 46.

[0033] The other end of the first spring 43 is fixedly connected to the mounting frame 42. The cover plate 48 has openings on both sides corresponding to the hook claw 44. The second spring 47 is located between the mounting plate 41 and the cover plate 48. The bottom surface of the cover plate 48 has a groove corresponding to the sealing strip 3. The skirt 2 has grooves on both sides corresponding to the hook claw 44. The bottom end of the second spring 47 is fixedly connected to the cover plate 48.

[0034] The specific implementation method is as follows: When sealing the lower mold 1, the connecting rod 45 is pulled to move the hook 44 to both sides and further compress the first spring 43. At the same time, the cover plate 48 is placed on the top surface of the lower mold 1 and fits against the skirt 2. At the same time, the mounting plate 41 is pressed down to move the hook 44 downward. When the hook 44 descends to a certain height, the connecting rod 45 is released and the hook 44 is moved by the first spring 43, so that the hook 44 contacts the notches on both sides of the skirt 2. Then the mounting plate 41 is released and the second spring 47 moves the mounting plate 41 and the hook 44 upward, so that the hook 44 hooks the grooves on both sides of the skirt 2.

[0035] The adjusting assembly 5 includes an airbag 56. A fixing plate 55 is fixedly installed on the top surface of the airbag 56. An inlet one-way valve 53 and an outlet one-way valve 54 are fixedly installed on the top surface of the fixing plate 55. An installation sleeve 52 is fixedly installed on the top of the inlet one-way valve 53 and the outlet one-way valve 54. A sealing plate 51 is slidably installed on the installation sleeve 52 through a groove opened therein. An air tube 59 is fixedly installed on the bottom end of the airbag 56. A baffle 58 is slidably installed inside the baffle 59. A round rod 57 is fixedly installed on the top surface of the baffle 58. The top end of the round rod 57 is fixedly connected to the fixing plate 55. The top surface of the fixing plate 55 is fixedly connected to the mounting plate 41. The airbag 56 is located between the mounting plate 41 and the cover plate 48. The inlet one-way valve 53 and the outlet one-way valve 54 are both fixedly connected to the mounting plate 41 through the through hole opened in the mounting plate 41. The air pipe 59 is fixedly connected to the cover plate 48 through the through hole opened in the cover plate 48.

[0036] The specific implementation method is as follows: When the mounting plate 41 is pressed, the inlet check valve 53 is first blocked by the sliding sealing plate 51, thereby compressing the airbag 56 when the mounting plate 41 is pressed. The round rod 57 drives the baffle 58 to move downward, thereby clearing the air pipe 59. At the same time, due to the compression of the airbag 56, the gas can be discharged outward from the outlet check valve 54. When the hook 44 is connected to the skirt 2 and the mounting plate 41 is moved upward by the second spring 47, the airbag 56 inflates and passes through the air pipe 59. The air tube 59 draws the gas from the lower mold 1 into the airbag 56. As the mounting plate 41 moves upward, the baffle 58 moves upward via the round rod 57, thus blocking the air tube 59. When the cover plate 48 is removed, the sealing plate 51 slides to the air outlet check valve 54. When the mounting plate 41 is pressed down, the hook 44 separates from the skirt 2, the airbag 56 is compressed, and the baffle 58 separates from the top of the air tube 59, allowing the gas in the airbag 56 to enter the lower mold 1.

[0037] Working principle: When sealing the lower mold 1, pulling the connecting rod 45 moves the hook 44 to both sides, further compressing the first spring 43. Simultaneously, the cover plate 48 is placed on the top surface of the lower mold 1 and abuts against the skirt 2. At the same time, pressing down the mounting plate 41 moves the hook 44 downwards. When the hook 44 descends to a certain height, the connecting rod 45 is released, and the first spring 43 moves the hook 44, bringing it into contact with the notches on both sides of the skirt 2. Then, the mounting plate 41 is released, and the second spring 47 moves the mounting plate 41 and hook 44 upwards, causing the hook 44 to hook onto the grooves on both sides of the skirt 2. When pressing the mounting plate 41, the sliding sealing plate 51 first blocks the air intake check valve 53, compressing the airbag 56 and releasing it through the round rod. 57 moves the baffle 58 downward, thereby clearing the air pipe 59. At the same time, the compression of the airbag 56 allows the gas to be discharged from the exhaust check valve 54. When the hook 44 is connected to the skirt 2 and the mounting plate 41 is moved upward by the second spring 47, the airbag 56 expands and draws the gas in the lower mold 1 into the airbag 56 through the air pipe 59. As the mounting plate 41 moves upward, the baffle 58 moves upward by the round rod 57, thereby blocking the air pipe 59. When the cover plate 48 is removed, the sealing plate 51 slides to the exhaust check valve 54. When the mounting plate 41 is pressed down, causing the hook 44 to separate from the skirt 2, the airbag 56 is compressed and the baffle 58 separates from the top of the air pipe 59, allowing the gas in the airbag 56 to enter the lower mold 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
