Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, and in particular to a novel mold frame with a positioning structure. Background Technology

[0002] A mold frame is a complete mold support structure for producing specific powder products. It is a semi-finished product of the mold and consists of components such as an ejection mechanism, a guiding mechanism, and mold foot pads. As a mold skeleton, it is widely used in the automotive, electronics, medical equipment, and powder metallurgy fields, and can be standardized or customized to meet different precision requirements.

[0003] A mold base typically consists of a front mold base plate, a front mold base, a rear mold base, square iron, a rear mold base plate, positioning components, and lifting components. The front and rear mold bases usually use guide pillars and guide sleeves as the mold closing and positioning structure. However, the front and rear mold bases are two independent units, and slight deviations that are not visible to the naked eye can easily occur during installation, leading to deviations between the guide pillars and guide sleeves. Under frequent mold closing, friction between the guide pillars and guide sleeves can easily cause wear on the inner wall of the guide sleeve and the outer wall of the guide pillar, affecting the positioning accuracy in later use, shortening the service life of the mold, and potentially affecting product quality. Therefore, a new type of mold base with a positioning structure is needed to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to provide a novel mold frame with a positioning structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel mold frame with a positioning structure, comprising a front mold frame base plate, a front mold frame, a rear mold frame, a positioning component, a square iron, a lifting component, a first rear mold frame base plate, and a second rear mold frame base plate. The front mold frame is connected to the front mold frame base plate, and the square iron is connected between the first rear mold frame base plate and the rear mold frame. A support base is connected to the second rear mold frame base plate. The top of the support base has a first sliding hole, a second sliding hole, and a third sliding hole sequentially formed from top to bottom. The inner diameters of the first sliding hole and the third sliding hole are... The same, and all are smaller than the inner diameter of the second sliding hole. Several return springs are connected to the bottom inner wall of the third sliding hole. The return springs are evenly arranged in a circumferential shape. A slide block is connected to the bottom end of the first rear mold base plate. The outer diameter of the upper part of the slide block is smaller than the outer diameter of the lower part of the slide block and smaller than the inner diameter of the first sliding hole. The upper part of the slide block is horizontally slidably connected in the first sliding hole, and the lower part of the slide block is horizontally slidably connected in the second sliding hole. The outer diameter is smaller than the inner diameter of the second sliding hole and larger than the inner diameter of the first sliding hole. The bottom end of the slide block is connected to the top of several return springs.

[0006] Preferably, the second rear mold base plate and the support base are fastened together by a number of corresponding countersunk holes, screw holes and hex bolts.

[0007] Preferably, a plurality of ball bearings are rotatably connected to the top of the support base, and the plurality of ball bearings are evenly arranged in a circumferential shape, with the bottom end of the first rear mold base plate in contact with the top end of the plurality of ball bearings.

[0008] Preferably, the top of the support base has a plurality of semi-circular holes, and each ball is rotatably connected in the corresponding semi-circular hole, wherein the diameter of the opening at the top of the semi-circular hole is smaller than the diameter of the ball.

[0009] Preferably, an annular rubber ring is provided on the inner wall of the second sliding hole.

[0010] Preferably, the first rear mold base plate and the slide are fastened together by a number of corresponding countersunk holes, screw holes and hex bolts.

[0011] Preferably, the first rear mold base plate, the slide, the support base, and the second rear mold base plate are all provided with through holes for the telescopic shaft of the lifting mechanism to pass through.

[0012] The beneficial effects of this utility model are: This invention utilizes a floating support structure consisting of a support base, a slide block, and a return spring. This structure enables the first rear mold base plate and its rear mold assembly to have a certain degree of self-adaptive fine-tuning capability before mold closing. When there is a slight deviation between the front mold base and the rear mold base during the mold closing process, this structure can absorb and compensate for the deviation through the horizontal sliding of the slide block within the support base and the deformation of the return spring. This avoids rigid friction and wear caused by forced correction between the guide pillar and the guide sleeve, effectively improving the mold closing positioning accuracy and extending the service life of the mold.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-6 A novel mold frame with a positioning structure includes a front mold frame base plate 1, a front mold frame 2, a rear mold frame 3, a positioning component 4, a square iron 5, a lifting component 6, a first rear mold frame base plate 7, and a second rear mold frame base plate 8. The front mold frame 2 is connected to the front mold frame base plate 1. The square iron 5 is connected between the first rear mold frame base plate 7 and the rear mold frame 3. A support base 9 is connected to the second rear mold frame base plate 8. The top of the support base 9 has a first sliding hole 10, a second sliding hole 11, and a third sliding hole 12 sequentially formed from top to bottom. The inner diameters of the first sliding hole 10 and the third sliding hole 12 are the same, and both are smaller than the inner diameter of the second sliding hole 11. The inner diameter of the third sliding hole 12 is connected to the inner wall of the bottom end of the third sliding hole 12. The return springs 13 are evenly arranged in a circumferential shape. The bottom end of the first rear mold base plate 7 is connected to the slide seat 14. The outer diameter of the upper seat of the slide seat 14 is smaller than the outer diameter of the lower seat and smaller than the inner diameter of the first sliding hole 10. The upper seat of the slide seat 14 is horizontally slidably connected in the first sliding hole 10, and the lower seat is horizontally slidably connected in the second sliding hole 11. The outer diameter is smaller than the inner diameter of the second sliding hole 11 and larger than the inner diameter of the first sliding hole 10. The bottom end of the slide seat 14 is connected to the top end of the return springs 13.

[0017] Specifically, in this embodiment, the second rear mold base plate 8 and the support base 9 are fastened together by a number of corresponding countersunk holes, screw holes and hex bolts to ensure a stable and reliable connection and to achieve the detachable effect between the support base 9 and the second rear mold base plate 8.

[0018] Specifically, in this embodiment, a number of ball bearings 15 are rotatably connected to the top of the support base 9. The ball bearings 15 are evenly arranged in a circumferential shape. The bottom end of the first rear mold base plate 7 contacts the top end of the ball bearings 15 to avoid friction between the first rear mold base plate 7 and the support base 9, improve the smoothness of movement, and at the same time provide horizontal and stable support for the first rear mold base plate 7.

[0019] Specifically, in this embodiment, a plurality of semi-circular holes 16 are provided in the top end of the support base 9, and each ball 15 is rotatably connected in the corresponding semi-circular hole 16. The diameter of the opening at the top end of the semi-circular hole 16 is smaller than the diameter of the ball 15 to prevent the ball 15 from falling off.

[0020] Specifically, in this embodiment, an annular rubber ring 17 is provided on the inner wall of the second sliding hole 11, which can effectively buffer the impact force at the moment of mold closing, play a role in shock absorption and noise reduction, and protect the mold frame structure.

[0021] Specifically, in this embodiment, the first rear mold base plate 7 and the slide block 14 are fastened together by a number of corresponding countersunk holes, screw holes and hex bolts to ensure the strength and stability of the connection and to achieve the detachable effect between the slide block 14 and the first rear mold base plate 7.

[0022] Specifically, in this embodiment, the first rear mold base plate 7, the slide 14, the support base 9, and the second rear mold base plate 8 are all provided with through holes 18 for the telescopic shaft of the lifting mechanism to pass through. A lifting mechanism with an outer diameter of telescopic shaft smaller than the inner diameter of through hole 18 can be selected to ensure that the slide 14 can smoothly drive the first rear mold base plate 7 and the upper mold frame assembly to adjust their position in the horizontal direction.

[0023] During the mold closing process, when the front mold frame 2 and the rear mold frame 3 are close together, if there is a slight centering deviation, the lateral force acting on the rear mold frame 3 will be transmitted to the first rear mold frame base plate 7 and the slide block 14. The slide block 14 compresses the return spring 13 on one side and produces a slight horizontal sliding in the first slide hole 10 and the second slide hole 11 of the support seat 9. At the same time, the first rear mold frame base plate 7 rolls on the ball bearing 15, thereby driving the entire rear mold frame 3 assembly to produce adaptive fine adjustment, achieving precise mold closing. After the mold closing force is removed, under the restoring force of the return spring 13, the slide block 14 and the first rear mold frame base plate 7 return to the initial center position. The rubber ring 17 can effectively absorb the impact and vibration of mold closing.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
