Description

Technical Field

[0001] This utility model relates to the field of auxiliary demolding structure production technology, and in particular to a demolding aid for hollow silicone rubber seals. Background Technology

[0002] Hollow silicone rubber seals, due to their excellent elasticity, temperature resistance, and sealing performance, are widely used in electronic equipment, automotive parts, and medical devices. After molding, they need to be removed from the mold through a demolding process. The demolding efficiency and the integrity of the finished product directly affect the production progress and product quality. These seals are mostly produced using compression molding. Due to the high viscosity of silicone rubber and the weak rigidity of the hollow structure, problems such as seals sticking to the inner wall of the mold, local tearing, or deformation can easily occur during demolding. Existing demolding auxiliary equipment lacks reliable synchronous ejection and anti-sticking designs. Simple mechanical ejection structures are mostly single-point ejection, and the concentrated ejection force can easily cause excessive local stress on the seals, leading to damage. At the same time, the poor stability of the fixed structure between the mold and the worktable means that the mold is prone to displacement due to vibration during demolding, resulting in deviation of the ejection position and exacerbating damage to the seals.

[0003] In view of the above reasons, this application proposes a demolding aid for hollow silicone rubber seals that enables rapid mold fixing and smooth demolding. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a demolding aid for hollow silicone rubber seals that enables rapid mold fixing and smooth demolding.

[0005] The technical solution of this utility model: a demolding aid for hollow silicone rubber seals, including a mounting base, a support frame fixedly provided on the top of the mounting base, a top plate fixedly provided on the top of the support frame, a plurality of push rod motors fixedly provided on the bottom of the top plate, the same upper template fixedly provided at the output end of the push rod motors, a pop-out structure fixedly provided on the top of the mounting base, and a lower template corresponding to the cavity of the upper template provided above the pop-out structure.

[0006] The bottom of the lower template is fixedly provided with an insert block, and a second locking block is provided on one side of the insert block. The pop-out structure includes a connecting plate. The top of the connecting plate is provided with multiple insertion holes and slots. A pull rod is movably provided on the front of the connecting plate. One end of the pull rod extends into the slot and is fixedly provided with a first locking block. Both the first locking block and the second locking block have inclined surfaces on their adjacent sides. The inclined surface on one side of the first locking block and the inclined surface on one side of the second locking block are parallel. A miniature drive cylinder is connected to the side of the pull rod located at the outer end of the connecting plate.

[0007] Optionally, the front of the connecting plate is provided with two round holes and a through hole, the through hole being located between the two round holes, the pull rod being movably connected to the through hole, and two limiting rods being fixedly provided on one side of the first locking block, the two limiting rods being movably connected to the two round holes.

[0008] Optionally, limiting grooves are provided on both inner walls of the slot, and limiting strips are fixedly provided on both sides of the insert block, with the limiting grooves and limiting strips being compatible.

[0009] Optionally, the top of the connecting plate is provided with multiple slots, each slot having a spring fixedly installed therein, and a connecting rod is movably installed on the top of the connecting plate, with a disc fixedly installed on the top of the connecting rod.

[0010] Optionally, a second spring is fitted onto the pull rod, with one end of the second spring fitting against one side of the first locking block, and the other end of the second spring fitting against the inner wall of the slot.

[0011] Optionally, a coolant filling pipe is fixedly provided at the top of the lower template, and multiple insert rods are fixedly provided at the bottom of the lower template. The insert rods are adapted to the insertion holes. A liquid storage chamber is provided inside the lower template, and a circulation structure is fixedly provided on one side of the lower template.

[0012] Optionally, the circulation structure includes a horizontal plate fixedly connected to one side of the lower template, a water pump fixedly mounted on the top of the horizontal plate, a water suction pipe and a water discharge pipe fixedly mounted on both sides of the water pump, and a plurality of heat dissipation fins fixedly mounted on the water discharge pipe.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention utilizes a pull rod, a locking block, a limiting rod, a spring, and a disc. Pulling the pull rod moves the locking block. When the locking block disengages from the locking block, multiple springs apply a pushing force to the lower mold plate. The lower mold plate moves upward rapidly under this force, and the two discs block the lower mold plate. The contact between the lower mold plate and the discs generates vibration, thereby assisting in demolding. Furthermore, the increased contact area prevents stress concentration during ejection, reducing the probability of damage to the seals. In cases where the finished product and mold are stuck together, there is no need for personnel to use clamps to remove the finished product. This not only improves the equipment's efficiency but also prevents the product from being damaged or deformed.

[0015] This utility model uses automated mechanical structure to fix and demold the mold, reducing manual intervention and lowering the difficulty of operation. The matching of the insertion rod and the insertion hole can be adapted to different specifications of the lower template. With the adjustable push rod motor stroke, it can meet the demolding requirements of hollow silicone rubber seals of various sizes, improve the versatility of the equipment, and adapt to multi-variety small batch production scenarios.

[0016] This invention utilizes a water pump and heat dissipation fins. The water pump draws in the coolant from the storage chamber and guides it into the storage chamber of the lower mold through a drain pipe. While the coolant is in the drain pipe, the heat dissipation fins cool the coolant, accelerating the cooling speed and enabling the liquid material in the lower mold to be formed quickly, thus ensuring the forming efficiency of the equipment.

[0017] In summary, the demolding aid proposed in this utility model, with synchronous drive and auxiliary ejection, achieves uniform ejection, reduces the breakage rate of seals, improves the pass rate, accelerates heat dissipation through the circulating cooling system, shortens cooling time, reduces dimensional deviations, facilitates mechanical automation, is compatible with multiple specifications of templates and seals, and has strong versatility.

[0040] Example

[0041] like Figures 1-4 As shown, the present invention proposes a hollow silicone rubber seal demolding aid, including a mounting base 1, a support frame 2 fixedly mounted on the top of the mounting base 1, a top plate 3 fixedly mounted on the top of the support frame 2, a plurality of push rod motors 4 fixedly mounted on the bottom of the top plate 3, the same upper template 5 fixedly mounted on the output end of the push rod motors 4, a pop-out structure 6 fixedly mounted on the top of the mounting base 1, and a lower template 7 corresponding to the cavity of the upper template 5 set above the pop-out structure 6.

[0042] Combination Figure 2As shown, the bottom of the lower template 7 is fixedly provided with an insert block 10, and a second locking block 11 is provided on one side of the insert block 10. The pop-out structure 6 includes a connecting plate 601. Limiting grooves are provided on both sides of the inner wall of the slot 603. Limiting strips that are adapted to the limiting grooves are fixedly welded to both sides of the insert block 10. The limiting strips are made of wear-resistant steel, which can prevent wear when the insert block slides, and at the same time ensure the accurate positioning of the lower template. The limiting grooves and limiting strips are adapted to each other to avoid lateral displacement of the lower template.

[0043] Reference Figure 3 As shown, the top of the connecting plate 601 has multiple slots, each containing a fixed spring 607. A connecting rod is movably mounted on the top of the connecting plate 601, and a disc 608 is fixedly mounted on the top of the connecting rod. The front of the connecting plate 601 has two round holes and a through hole, with the through hole located between the two round holes. The top of the connecting plate 601 has multiple insertion holes 602 and slots 603. A pull rod 604 is movably mounted on the front of the connecting plate 601. One end of the pull rod 604 extends into the slot 603 and is fixedly mounted with a locking block 605. A second spring is fitted on the pull rod 604, providing preload to ensure a tight fit between the locking block 1 and the locking block 2. One end of the second spring and the locking block 1... One side of 605 is fitted, and the other end of spring 2 is fitted with the inner wall of slot 603; pull rod 604 is movably connected to through hole; two limit rods 606 are fixedly provided on one side of the first locking block 605. The limit rods can prevent the pull rod from rotating and ensure that the inclined surface of the first locking block and the inclined surface of the second locking block are precisely matched. The two limit rods 606 are movably connected to two round holes. Both the first locking block 605 and the second locking block 11 have inclined surfaces on the side that are close to each other. The inclined surface design makes it easy to automatically push the first locking block to move when the plug is inserted, so as to achieve quick locking. The inclined surface on one side of the first locking block 605 and the inclined surface on one side of the second locking block 11 are parallel. A miniature drive cylinder 609 is connected to the side of the pull rod 604 located at the outer end of the connecting plate 601.

[0044] Combination Figure 1 and Figure 4 As shown, a coolant injection pipe 8 is fixedly installed on the top of the lower template 7, and multiple stainless steel rods are fixedly installed on the bottom of the lower template 7 by welding. Stainless steel has high strength and is not easy to rust. The rods and the insertion holes can further improve the stability of the lower template. The rods 9 and the insertion holes 602 are compatible. The lower template 7 has a liquid storage chamber inside, which can hold a sufficient amount of coolant to achieve uniform cooling of the mold. A circulation structure 12 is fixedly installed on one side of the lower template 7. The circulation structure 12 includes a horizontal plate 121 fixedly connected to one side of the lower template 7. The horizontal plate can stably support the water pump. A water pump 122 is fixedly installed on the top of the horizontal plate 121. The water pump 122 is a micro water pump. The micro water pump is small in size and has a stable flow rate, which can drive the coolant circulation. A suction pipe 123 and a drain pipe 124 are fixedly installed on both sides of the water pump 122, respectively. Multiple aluminum alloy heat dissipation fins 125 are fixedly fitted on the drain pipe 124. Aluminum alloy has good thermal conductivity and can quickly dissipate the heat in the coolant to improve the cooling efficiency.

[0045] In this embodiment, the insertion rod 9 at the bottom of the lower template 7 is first aligned with the insertion hole 602 of the connecting plate 601, and the limiting strips on both sides of the insertion block 10 are inserted along the limiting groove of the slot 603. During the insertion process, the inclined surface of the second locking block 11 on one side of the insertion block 10 contacts the inclined surface of the first locking block 605, driving the micro-drive cylinder 609 to push the first locking block 605 to move the pull rod 604 to the outside of the connecting plate 601. At this time, the second spring is compressed. When the insertion block 10 is fully inserted into the slot 603, the micro-drive cylinder 609 reverses its operation, and the second spring elastically rebounds, pushing the first locking block 605 to reset and tightly engage with the second locking block 11 to fix the lower template 7.

[0046] After the hollow silicone rubber seal is molded by the upper and lower mold plates, coolant is injected into the annular reservoir inside the lower mold plate 7 through the copper coolant injection pipe 8 at the top of the lower mold plate 7. The micro water pump 122 on the horizontal plate 121 is started. The water pump 122 draws the warm coolant from the reservoir through the PVC suction pipe 123. When it is transported through the drain pipe 124, the aluminum alloy heat dissipation fins 125 outside the drain pipe 124 quickly dissipate the heat in the coolant. The cooled coolant flows back into the reservoir, forming a circulating cooling system, so that the lower mold plate 7 and the internal seal are cooled evenly, avoiding the problems of long natural cooling time or uneven temperature of external water cooling, and quickly cooling the seal to a suitable demolding temperature.

[0047] After cooling is complete, multiple DT series push rod motors 4 at the bottom of the top plate 3 are activated. The push rod motors 4 synchronously drive the upper aluminum alloy template 5 to move upward smoothly and separate from the lower template 7. Then, the micro drive cylinder 609 is activated, and the pull rod 604 is pulled outward. The pull rod 604 drives the first locking block 605. When the first locking block 605 disengages from the second locking block 11, multiple springs 607 apply a pushing force to the lower template 7. The lower template 7 moves upward rapidly under the force. As the lower template 7 is pushed upward, it suddenly contacts the lower surface of the disc 608. The two discs 608 will block the lower template 7 and generate vibration, thereby achieving the purpose of assisting demolding.

[0048] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
