Description

Technical Field

[0001] This utility model relates to the field of production mold technology, specifically a precision metal product production mold for quick demolding. Background Technology

[0002] In the traditional field of precision metal product manufacturing, the mold technology employed has revealed numerous problems that urgently need to be addressed. Existing metal product manufacturing molds face the dilemma of low efficiency in the demolding process. In most cases, the demolding process relies on manual operation or simple mechanical assistance. Manual demolding is not only labor-intensive but also extremely inefficient, making it difficult to meet the fast-paced demands of large-scale industrial production. Demolding methods relying on simple mechanical assistance, due to technological limitations, often result in an uneven demolding process, significantly extending the production cycle.

[0003] From the perspective of product quality, traditional molds are prone to damage during demolding. For example, during the demolding process, the ejection force of the ejector device is difficult to distribute evenly, often resulting in scratches, deformation, and other defects on the surface of precision metal products. This seriously affects product quality and yield, and increases production costs. Utility Model Content

[0004] The purpose of this invention is to provide a rapid demolding precision metal product manufacturing mold, solving the technical problems of low demolding efficiency and easy damage to products caused by traditional metal product manufacturing molds. This achieves the goals of improving production efficiency, ensuring product quality, and enhancing mold stability and reliability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release precision metal product manufacturing mold, comprising a support fixing plate, a quick-release part, and a lifting mold closing forming part, wherein support pads are symmetrically fixedly installed on the bottom outer wall of the support fixing plate; the quick-release part is disposed on the top of the support fixing plate; and the lifting mold closing forming part is disposed on the top of the quick-release part.

[0006] Preferably, the quick demolding part specifically includes: a support fixing plate, symmetrically fixedly installed on the top outer wall of the support fixing plate; a fixing lug, fixedly installed on the top outer wall of the support fixing plate; and a support fixing frame, disposed on the top of the support fixing plate.

[0007] Preferably, a lower mold is fixedly installed between the fixed ear blocks, the support fixing frame is fixedly installed on the bottom outer wall of the lower mold, a pneumatic telescopic rod is fixedly installed inside the support fixing frame, a forming chamber is opened inside the lower mold, an interlocking groove is opened at the bottom of the inner wall of the forming chamber, and side plate sliding grooves are fixedly installed at equal intervals around the inner wall of the lower mold.

[0008] A molding chamber is installed, which works in conjunction with a support frame and a pneumatic telescopic rod. After the product is molded, the pneumatic telescopic rod can precisely drive the demolding top plate and demolding side plate to rise from the bottom of the molding chamber, achieving rapid demolding and effectively shortening the production cycle. The side plate grooves on the inner wall of the molding chamber slide in conjunction with the demolding side plate, playing a guiding role in the demolding process, ensuring smooth demolding action and avoiding damage to the product due to uneven force.

[0009] Preferably, a demolding top plate is fitted inside the fitting groove, and demolding side plates are fixedly installed at equal intervals around the top circumference of the demolding top plate. The demolding side plates are slidably installed inside the side plate groove. An opening is provided on the inner wall of the fitting groove, and the telescopic end of the pneumatic telescopic rod extends into the interior of the fitting groove through the opening.

[0010] A pneumatic telescopic rod is installed, which works in conjunction with the support frame, demolding top plate, and demolding side plate. After the metal product is formed, it can precisely drive the demolding top plate and demolding side plate to rise from the bottom of the forming chamber. The support frame provides a stable installation base for the pneumatic telescopic rod, ensuring that its thrust can be transmitted stably and that the demolding action is fast and powerful, effectively shortening the demolding time. The demolding side plate slides in conjunction with the side plate groove on the inner wall of the forming chamber. When the pneumatic telescopic rod pushes the demolding top plate up, the side plate groove plays a guiding role, ensuring that the demolding side plate moves smoothly and avoiding damage to the product due to uneven force during the demolding process, thus improving the product yield.

[0011] Preferably, the telescopic end of the pneumatic telescopic rod is fixedly connected to the bottom outer wall of the demolding top plate, and a sliding rod is fixedly connected circumferentially to the bottom outer wall of the demolding top plate.

The other end of the spring is fixedly connected to the top outer wall of the limiting plate and the other end of the spring is fixedly connected to the bottom outer wall of the lower mold.

[0013] Preferably, the lifting and mold-closing forming part specifically includes: a support guide rod, symmetrically fixedly installed on the top outer wall of the fixed ear block; a support plate is fixedly installed on the top outer wall of the support guide rod, a hydraulic telescopic rod frame is fixedly installed on the top outer wall of the support plate, a hydraulic telescopic rod is fixedly installed inside the hydraulic telescopic rod frame, connecting rods are symmetrically fixed on the bottom outer wall of the support plate, the other end of the connecting rod is connected to the top outer wall of the lower mold, and the telescopic end of the hydraulic telescopic rod movably penetrates the top outer wall of the support plate and extends to the bottom of the support plate.

[0014] Preferably, a mold closing upper mold cover is fixedly installed at the telescopic end of the hydraulic telescopic rod. A positioning sleeve is fixed on the top outer wall of the mold closing upper mold cover. The positioning sleeve is sleeved on the outer wall of the telescopic end of the hydraulic telescopic rod. Guide sleeves are symmetrically installed on the bottom outer wall of the mold closing upper mold cover. The mold closing upper mold cover is movably sleeved on the outer wall of the supporting guide rod through the guide sleeves. The mold closing upper mold cover is adapted to the molding chamber. A feed pipe is provided inside the mold closing upper mold cover.

[0015] A feed pipe is installed, and its coordination with other mold components provides strong support for the efficient production of precision metal products. During the metal product forming process, the feed pipe is tightly connected to the upper mold cover of the mold closing mechanism. The upper mold cover moves downward along the support guide rod via a guide sleeve, forming a closed forming chamber with the lower mold. The feed pipe passes through the upper mold cover, enabling the delivery of metal raw materials into the forming chamber after mold closing. This design ensures a smooth and stable raw material injection process, avoiding material waste and product defects caused by spillage or injection position deviations, thus guaranteeing the quality of the formed metal products.

[0016] This invention provides a quick-release precision metal product manufacturing mold. It has the following beneficial effects:

[0017] (1) This utility model uses a pneumatic telescopic rod to directly act on the demolding top plate. By exerting force through the through-hole, it can quickly push the demolding top plate and demolding side plate to rise in the side plate slide groove, and quickly eject the metal products in the molding chamber, shortening the demolding time. The sliding fit between the demolding side plate and the side plate slide groove, as well as the locking design between the demolding top plate and the fitting groove, not only ensure the smoothness of the demolding process, but also protect the metal products. The demolding side plate rises smoothly along the side plate slide groove, and the force is uniform when ejecting the metal products, avoiding defects such as scratches and deformation on the surface of the products due to uneven force, and effectively improving the product qualification rate.

[0018] (2) This utility model enables the upper mold cover to be positioned during the lifting and lowering process by the cooperation of the support guide rod and the guide sleeve, avoiding deviation and shaking, ensuring that the upper mold cover and the lower mold are tightly fitted to form a molding chamber with accurate dimensions and good sealing, laying the foundation for high-precision molding of metal products, effectively ensuring the dimensional accuracy and appearance quality of the products. The positioning sleeve is fitted on the outer wall of the extension end of the hydraulic telescopic rod, further enhancing the stability of the hydraulic telescopic rod during the extension and retraction process, preventing it from tilting during operation, and ensuring the reliability of the mold closing and demolding actions.

[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0027] Addressing the problems of low demolding efficiency and easy damage to products caused by traditional metal product manufacturing molds, this utility model provides a preferred embodiment of a rapid demolding precision metal product manufacturing mold, for example... Figures 1-5 As shown: A quick-release precision metal product manufacturing mold includes a fixed plate 1, a quick-release part 3, and a lifting mold closing forming part 4. Support pads 2 are symmetrically fixedly installed on the bottom outer wall of the fixed plate 1; the quick-release part 3 is located on the top of the fixed plate 1; and the lifting mold closing forming part 4 is located on the top of the quick-release part 3.

[0028] The quick demolding part 3 specifically includes: a support fixing plate 311, which is symmetrically fixedly installed on the top outer wall of the fixing plate 1; a fixing ear block 312, which is fixedly installed on the top outer wall of the support fixing plate 311; and a support fixing frame 313, which is set on the top of the fixing plate 1.

[0029] A lower mold 315 is fixedly installed between the fixed ear blocks 312. A support frame 313 is fixedly installed on the bottom outer wall of the lower mold 315. A pneumatic telescopic rod 314 is fixedly installed inside the support frame 313. A forming chamber 316 is opened inside the lower mold 315. A fitting groove 3111 is opened at the bottom of the inner wall of the forming chamber 316. Side plate sliding grooves 317 are fixedly installed at equal intervals around the inner wall of the lower mold 315.

[0030] The inner wall of the fitting groove 3111 is fitted with a demolding top plate 3115. The top circumference of the demolding top plate 3115 is fixedly fitted with demolding side plates 319 at equal intervals. The demolding side plates 319 are slidably installed inside the side plate slide groove 317. The inner wall of the fitting groove 3111 is provided with a through opening 318. The telescopic end of the pneumatic telescopic rod 314 extends into the interior of the fitting groove 3111 through the through opening 318.

[0031] The telescopic end of the pneumatic telescopic rod 314 is fixedly connected to the bottom outer wall of the demolding top plate 3115. The bottom outer wall of the demolding top plate 3115 is circumferentially fixedly connected with a sliding rod 3113. The other end of the sliding rod 3113 movably passes through the bottom outer wall of the fitting groove 3111 and extends to the bottom outer wall of the mold 315.

[0032] The other end of the slide bar 3113 is fixedly installed with a limiting plate 3114. A spring 3112 is movably sleeved on the outer wall of the slide bar 3113. The other end of the spring 3112 is fixedly connected to the top outer wall of the limiting plate 3114, and the other end of the spring 3112 is fixedly connected to the bottom outer wall of the lower mold 315.

[0033] In this embodiment, the pneumatic telescopic rod 314 inside the support frame 313 is activated. The telescopic end of the pneumatic telescopic rod 314 pushes the demolding top plate 3115 upward within the fitting groove 3111 through the through-hole 318. The demolding top plate 3115 drives the demolding side plates 319, which are equidistantly installed on the top circumference, to rise synchronously along the side plate slide groove 317, ejecting the metal product from the molding chamber 316 and completing the rapid demolding operation. During this process, the slide rod 3113 at the bottom of the demolding top plate 3115 slides at the bottom of the fitting groove 3111, and the limiting plate 3114 and the return spring 3 112 together ensure the smoothness and accuracy of the demolding process, enabling the demolding top plate and demolding side plate to rise quickly within the side plate slide groove, rapidly ejecting the metal product from the molding chamber and shortening the demolding time. The sliding fit between the demolding side plate and the side plate slide groove, as well as the locking design between the demolding top plate and the fitting groove, not only ensure the smoothness of the demolding process but also protect the metal product. The demolding side plate rises smoothly along the side plate slide groove, and the force is even when ejecting the metal product, avoiding defects such as scratches and deformation on the product surface due to uneven force, effectively improving the product qualification rate. Example

[0034] Please see Figures 1-5 Furthermore, based on Embodiment 1, the lifting and closing molding part 4 specifically includes: a support guide rod 411, symmetrically fixedly installed on the top outer wall of the fixed ear block 312; a support plate 413 is fixedly installed on the top outer wall of the support guide rod 411; a hydraulic telescopic rod frame 417 is fixedly installed on the top outer wall of the support plate 413; a hydraulic telescopic rod 415 is fixedly installed inside the hydraulic telescopic rod frame 417; a connecting rod 412 is symmetrically fixed on the bottom outer wall of the support plate 413; the other end of the connecting rod 412 is connected to the top outer wall of the lower mold 315; the telescopic end of the hydraulic telescopic rod 415 moves through the top outer wall of the support plate 413 and extends to the bottom of the support plate 413.

[0035] The telescopic end of the hydraulic telescopic rod 415 is fixedly equipped with a mold closing upper mold cover 419. A positioning sleeve 418 is fixed on the top outer wall of the mold closing upper mold cover 419. The positioning sleeve 418 is sleeved on the outer wall of the telescopic end of the hydraulic telescopic rod 415. Guide sleeves 414 are symmetrically installed on the bottom outer wall of the mold closing upper mold cover 419. The mold closing upper mold cover 419 is movably sleeved on the outer wall of the supporting guide rod 411 through the guide sleeves 414. The mold closing upper mold cover 419 is compatible with the molding chamber 316. A feed pipe 416 is provided inside the mold closing upper mold cover 419.

[0036] In this embodiment, the hydraulic telescopic rod 415 inside the hydraulic telescopic rod frame 417 is activated. The hydraulic telescopic rod 415 drives the upper mold cover 419 to move downward along the support guide rod 411. During this process, the guide sleeve 414 at the bottom of the upper mold cover 419 slides on the support guide rod 411 to ensure the precise descent of the upper mold cover 419. When the upper mold cover 419 and the lower mold 315 are completely fitted together, a closed molding chamber 316 is formed, completing the mold closing operation. This effectively ensures the dimensional accuracy and appearance quality of the product. The positioning sleeve is fitted on the outer wall of the telescopic end of the hydraulic telescopic rod, further enhancing the stability of the hydraulic telescopic rod during the telescopic process and preventing it from tilting during operation, thus ensuring the reliability of the mold closing and demolding actions.

[0037] Working principle: When using:

[0038] Step 1: Place the fixing plate 1 on a flat and stable work site. Use the support pads 2 symmetrically installed at its bottom to ensure the overall stability of the mold. Check the connection status of each component of the quick demolding part 3 and the lifting mold closing forming part 4. Ensure that the supporting fixing plate 311, fixing ear block 312, supporting fixing frame 313 and other components are firmly installed, and that the power devices such as pneumatic telescopic rod 314 and hydraulic telescopic rod 415 are in normal standby state.

[0039] Step 2: Activate the hydraulic telescopic rod 415 inside the hydraulic telescopic rod frame 417. The hydraulic telescopic rod 415 drives the upper mold cover 419 to move downward along the support guide rod 411. During this process, the guide sleeve 414 at the bottom of the upper mold cover 419 slides on the support guide rod 411 to ensure that the upper mold cover 419 descends accurately. When the upper mold cover 419 and the lower mold 315 are completely fitted together, a closed molding chamber 316 is formed, and the mold closing operation is completed.

[0040] Step 3: The metal raw material is injected into the molding chamber 316 through the feed pipe 416 set inside the mold cover 419. During the injection process, the raw material is evenly distributed to provide sufficient material for the molding of metal products.

[0041] Step 4: After the raw material is injected, keep the mold closed and allow the metal raw material to undergo a certain period of cooling and solidification in the forming chamber 316 to complete the forming of the precision metal product.

[0042] Step 5: After the metal product is formed, activate the hydraulic telescopic rod 415 to drive the mold cover 419 to move upward along the support guide rod 411, open the mold, and leave space for demolding operation;

[0043] Step Six: Activate the pneumatic telescopic rod 314 inside the support frame 313. The telescopic end of the pneumatic telescopic rod 314 pushes the demolding top plate 3115 upward in the fitting groove 3111 through the through port 318. The demolding top plate 3115 drives the demolding side plates 319, which are equidistantly installed on the top circumference, to rise synchronously along the side plate slide groove 317, pushing out the metal product in the molding chamber 316 and completing the rapid demolding operation. During this process, the slide rod 3113 at the bottom of the demolding top plate 3115 slides at the bottom of the fitting groove 3111. The limiting plate 3114 and the return spring 3112 together ensure the stability and accuracy of the demolding process.

[0044] Step 7: After demolding is completed, close the pneumatic telescopic rod 314. Under the action of the return spring 3112, the demolding top plate 3115 and demolding side plate 319 will return to their original positions along the original path. Then, start the hydraulic telescopic rod 415 again to lower the mold closing cover 419, so that the mold is restored to the mold closing preparation state and ready for the next production.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
