Description

Technical Field

[0001] This utility model relates to the technical field of fluororubber product processing equipment, and specifically to a molding device. Background Technology

It possesses high-temperature resistance, chemical resistance, oil resistance, and oxidation resistance, and is widely used in various manufacturing fields. However, under normal processing conditions (especially at room temperature or low temperatures), fluororubber exhibits characteristics of hardness, high viscosity, and poor flowability. When fluororubber in this state is placed into a mold for mold closing, it cannot smoothly fill all angles of the mold, leading to unclear outlines and air trapping in the fluororubber products.

[0021] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figures 1 to 5 This application provides a molding apparatus. It includes a worktable 1, a molding assembly 2, a storage tank 3, and a drive assembly 4.

[0024] For ease of description, Figure 1 The Z-direction defines the up and down directions, with Figure 1 The X direction is defined as the first direction, which is perpendicular to the vertical direction in this application. It is understood that the perpendicularity in this application is not absolute. Approximate perpendicularity due to processing and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of the perpendicularity in this application.

[0025] The workbench 1 has an injection station 10 and a molding station 11 arranged along a first direction to spatially separate the injection process and the molding process.

[0026] The molding assembly 2 includes an upper mold 20, a lower mold 21, and a displacement assembly 22 that drives at least one of the upper mold 20 or the lower mold 21 to move in the vertical direction. The upper mold 20 and the lower mold 21 are engaged with each other under the drive of the displacement assembly 22 to achieve mold closing and mold opening actions. The upper mold 20 is located at the molding station 11, and the lower mold 21 is provided with a molding cavity 210.

[0027] It should be noted that the molding cavity 210 referred to in this application is not limited to... Figure 1 The simplified frame structure shown in the diagram is for illustrative purposes only; it refers to all cavity structures within the mold used for molding fluororubber products. That is, this application does not limit the specific structure of the upper mold 20 and the lower mold 21, which can be adaptively designed and adjusted according to the shape and size of the fluororubber product.

[0028] The storage tank 3 is located at the injection station 10 and is used to temporarily store fluororubber compound. The storage tank 3 includes a material chamber 30, a heating element 31 for heating the material chamber 30, an inlet 32 ​​and an outlet 33 connected to the material chamber 30. The inlet 32 ​​is used to fill the fluororubber compound to be preheated, and the outlet 33 is used to discharge the preheated fluororubber compound.

[0029] The driving component 4 is used to drive the lower mold 21 to move along a first direction, so that the lower mold 21 moves between the injection station 10 and the molding station 11.

[0030] This invention adds a storage tank 3 to temporarily store the fluororubber compound, and a heating element 31 preheats the compound, allowing it to soften beforehand. This fundamentally solves the problems of incomplete filling and material accumulation in the molding cavity 210 due to the poor flowability of the fluororubber compound, thus significantly improving the molding quality of fluororubber products. Furthermore, during subsequent molding, the preheated fluororubber compound, with its excellent flowability, can fully fill all corners of the molding cavity 210, effectively preventing unclear outlines and air entrapment in the fluororubber products.

[0031] The separate design of the injection station 10 and the molding station 11, and the movement of the lower mold 21 between the injection station 10 and the molding station 11 driven by the drive component 4, allows the preheating process of the storage tank 3 and the molding process of the molding component 2 to be carried out in parallel, thereby improving efficiency.

[0032] In one application scenario, when the drive component 4 drives the lower mold 21 to move to the molding station 11, and the upper mold 20 and the lower mold 21 perform the mold closing action, the storage tank 3 can simultaneously preheat the fluororubber material to shorten the cycle time and improve the production cycle.

[0033] In a specific application scenario, the processing flow of the molding device is as follows: First, the fluororubber compound, which is at low or normal temperature, is injected into the storage tank 3 through the inlet 32. The compound is then preheated by the heating element 31 integrated into the storage tank 3 to soften it and improve its flowability.

[0034] Next, the drive assembly 4 drives the lower mold 21 to the injection station 10. The preheated fluororubber compound is injected into the molding cavity 210 of the lower mold 21 through the outlet 33. Since the compound has been softened at this time, its fluidity is strong, allowing the fluororubber compound to fully fill all areas of the molding cavity 210.

[0035] Subsequently, the drive assembly 4 drives the lower mold 21 filled with fluororubber material to the molding station 11. The displacement assembly 22 then drives one of the upper mold 20 or the lower mold 21, causing the upper mold 20 and the lower mold 21 to move towards each other and perform a mold closing action. Of course, the displacement assembly 22 can drive the upper mold 20 to move vertically to press against the lower mold 21, or it can drive the lower mold 21 to move vertically to fit against the upper mold 20, or it can drive the upper mold 20 and the lower mold 21 to move towards each other simultaneously to perform a mold closing action.

[0036] While researching related technologies, the inventors discovered two existing solutions in the industry for improving the flowability of fluororubber. One solution involves using a high-temperature mold with active heating for molding. While this method ensures complete filling of the fluororubber compound, the high manufacturing and maintenance costs of temperature-controlled molds, coupled with the difficulty of replacement, result in poor economic viability of the final fluororubber products.

[0037] Option two involves using an external, integrated heating device to heat a large quantity of fluororubber compound to the required temperature before transferring it as a whole and molding it in batches. However, in this process, the fluororubber compound may lose heat during preheating and transfer to the mold, leading to unstable preheating results. Especially for small or precision-structured fluororubber products, this large-scale, external preheating method makes it difficult to guarantee the flowability of the fluororubber compound during molding.

[0038] Compared to Schemes 1 and 2 mentioned above, this application's method of temporarily storing and preheating the fluororubber compound in the storage tank 3 has extremely low cost. After preheating the fluororubber compound in the storage tank 3, it is directly injected into the lower mold 21, and the lower mold 21 is immediately moved to the molding station 11 on the same workbench 1 to perform the molding action. This "heat and press immediately" method greatly shortens the exposure time of the preheated fluororubber compound in the air, effectively preventing heat loss.

[0039] To further ensure the precise positioning of the lower mold 21, the worktable 1 also has a guide groove 12 extending along the first direction. The lower mold 21 slides in conjunction with the guide groove 12 to provide a rigid physical constraint for the reciprocating movement of the lower mold 21, forcing it to displace along the first direction.

[0040] In a specific application scenario, the workbench 1 has multiple support legs 15, which together lift the table surface of the workbench 1 to improve the stability of the molding device.

[0041] The molding device also includes a frame 6, which is connected to the worktable 1.

[0042] Specifically, the frame 6 is provided with a first fixing frame 60 at the molding station 11, which is connected to the upper mold 20. This allows the upper mold 20 to move vertically under the drive of the displacement component 22. The frame 6 may also be provided with a second fixing frame 61 at the injection station 10, which is connected to the storage tank 3.

[0043] The first fixing frame 60 and the second fixing frame 61 are spaced apart along the first direction. This design allows the lower mold 21 to move only on the plane of the worktable 1, reducing the difficulty of driving the lower mold 21 to move.

[0044] The second fixing bracket 61 is connected to the rigid middle tank body of the storage tank 3 to stably suspend the storage tank 3 above the injection station 10. This facilitates the precise injection of the preheated fluororubber compound into the molding cavity 210 of the lower mold 21.

[0045] In one possible implementation, in order to efficiently heat the fluororubber compound temporarily stored in the storage tank 3, the heating element 31 is fitted onto the storage tank 3 to form a stable, circumferential heating and to make the temperature distribution within the entire material chamber 30 more uniform.

[0046] like Figure 2 As shown, the inlet 32 ​​and outlet 33 of the storage tank 3 are distributed at both ends of the storage tank 3 in the vertical direction. The heating element 31 is coaxially sleeved on the circumferential side wall of the storage tank 3 to radiate heat evenly to the internal fluororubber material.

[0047] Furthermore, the heating element 31 includes a first heating ring 310 and a second heating ring 311 spaced apart in the vertical direction, which are sleeved on the storage tank 3. The first heating ring 310 is located at the end of the storage tank 3 near the inlet 32, and the second heating ring 311 is located at the end of the storage tank 3 near the outlet 33. In this way, the first heating ring 310 and the second heating ring 311 can heat the main body of the tube in sections to expand the effective heating area and ensure the uniform heating of the fluororubber compound.

[0048] The storage tank 3 also includes a weight sensor 34 and an electric valve 35 communicatively connected to the weight sensor 34. The electric valve 35 can open or close the discharge port 33 and is located at the discharge port 33. This ensures that when the fluororubber material in the material chamber 30 reaches the preset threshold of the weight sensor 34, the weight sensor 34 will send a signal to close the electric valve 35, thereby ensuring that the amount of fluororubber material injected into the material chamber 30 each time is accurate, thus further avoiding defects in fluororubber products caused by excessive or insufficient material.

[0049] After the heating element 31 starts heating until the fluororubber material in the storage tank 3 is preheated, the electric valve 35 opens the discharge port 33, and the fluororubber material falls from the discharge port 33 into the molding cavity 210 that is connected to the discharge port 33.

[0050] For example, the discharge port 33 is specifically constructed as a guide pipe, fixed to the bottom of the storage tank 3 and extending downward in the vertical direction. This guides the softened fluororubber material with high fluidity into the molding cavity 210.

[0051] After the fluororubber compound in the storage tank 3 is injected, the electric valve 35 continues to close the outlet 33, and the next batch of fluororubber compound can be filled into the storage tank 3. Simultaneously, the drive assembly 4 drives the lower mold 21 filled with fluororubber compound to move to the molding station 11 to perform the mold closing action and manufacture fluororubber products.

[0052] To facilitate the collection of molded fluororubber products, the workbench 1 also has a demolding station. Depending on the positional relationship between the demolding station, the injection station 10, and the molding station 11, the following situations can be identified.

[0053] In one application scenario, the demolding station, the injection station 10, and the molding station 11 are arranged along a first direction. At this time, the driving component 4 is used to drive the lower mold 21 to move between the injection station 10, the molding station 11, and the demolding station.

[0054] For example, the demolding station can be located on the side of the injection station 10 away from the molding station 11 (e.g., Figure 1As shown, the demolding station, the injection station 10, and the molding station 11 are arranged sequentially along the first direction; or located on the side of the molding station 11 away from the injection station 10, so that operators can safely and conveniently collect fluororubber products.

[0055] Alternatively, in another application scenario, the demolding station can be co-located with the injection station 10 / molding station 11. In this case, the driving component 4 is used to drive the lower mold 21 to move between the injection station 10 and the molding station 11.

[0056] For example, if the demolding station and the molding station 11 are located together, the demolding action can be completed directly at the molding station 11, and demolding is performed after the mold is closed and opened; or if the demolding station and the injection station 10 are located together, demolding is performed first when returning to the injection station 10, and then injection is performed, so as to save equipment space.

[0057] In one specific embodiment, the molding apparatus further includes a demolding mechanism to perform automated demolding. The demolding mechanism includes a top plate 50 located in the molding cavity 210 and a lifting member 51 that drives the top plate 50 to move along the vertical direction. When the lower mold 21 is in the demolding position, the lifting member 51 drives the top plate 50 to rise along the vertical direction, thereby ejecting the fluororubber product located in the molding cavity 210 from the molding cavity 210.

[0058] Specifically, such as Figure 6 and Figure 7 As shown, the demolding mechanism also includes a third fixing frame 52 connected to the bottom of the lower mold 21, which can move together with the lower mold 21 in the guide groove 12.

[0059] The fixed end of the lifting component 51 is installed on the third fixed frame 52, and the movable end is connected to the lifting rod 51 to drive the lifting rod 51 to move, thereby improving space utilization.

[0060] For example, the lifting member 51 is an electric push rod.

[0061] In one possible application scenario, the aforementioned support leg 15 forms a space below the workbench 1, and the fixed ends of the third fixing frame 52 and the lifting member 51 can always be located within the space defined by the support leg 15 to avoid interfering with other equipment.

[0062] In one specific embodiment, the driving assembly 4 includes a driving rod 40 extending along the first direction and a driving source 41 connected to the driving rod 40. The driving rod 40 is connected to the lower mold 21, and the driving source 41 directly drives the driving rod 40 to extend and retract or reciprocate along the first direction, thereby driving the lower mold 21 to reciprocate along the first direction, thus enabling back-and-forth transfer between the injection station 10 and the molding station 11.

[0063] In another specific embodiment, the drive rod 40 includes a lead screw 400 and a guide rod 401 arranged in parallel on both sides of the lower mold 21. The drive source 41 is rotatably connected to the lead screw 400 to convert the rotational motion of the drive source 41 into the linear motion of the lower mold 21. This lead screw 400 transmission method can have high repeatability and self-locking capability, ensuring that the lower mold 21 can accurately remain stationary at the injection station 10, molding station 11, and molding station 12, and cooperate with the corresponding storage tank 3 and upper mold 20 respectively.

[0064] For example, the drive source 41 is a drive motor.

[0065] To cooperate with the lead screw 400 and the guide rod 401, the lower mold 21 includes a first lug 211 sleeved on the lead screw 400 and a second lug 212 sleeved on the guide rod 401. The lead screw 400, which is responsible for transmission, and the guide rod 401, which is responsible for guidance, are arranged parallel to each other on both sides of the lower mold 21 to effectively prevent the lower mold 21 from shifting, shaking, or jamming during movement.

[0066] The molding device is also equipped with a control system, which is communicatively connected to at least one or more of the drive assembly 4, the displacement assembly 22, and the storage tank 3.

[0067] In one specific implementation, the control system includes a first position sensor 13 that is communicatively connected to the drive assembly 4. The first position sensor 13 can monitor the current position of the lower mold 21 in real time and can trigger control actions according to preset target positions (such as injection station 10, molding station 11).

[0068] In one application scenario, if the first position sensor 13 detects that the lower mold 21 has moved to a predetermined station (such as the injection station 10 or the molding station 11), it can send a signal to the drive source 41 to stop moving the lower mold 21, so as to accurately control the distance that the drive rod 40 drives the lower mold 21 to move.

[0069] For example, the first position sensor 13 is disposed on the workbench 1 and may be located on the side of the workbench 1 close to the molding station 11, so as to directly monitor the displacement of the lower mold 21 in the first direction.

[0070] In another possible implementation, the control system further includes a second position sensor 14 communicatively connected to the displacement component 22. The second position sensor 14 is used to monitor the current position of the upper mold 20 in real time. If the upper mold 20 reaches a preset target position (such as the rising position of the upper mold 20 or the closing position of the upper mold 20), the displacement component 22 drives the upper mold 20 to rise or fall.

[0071] In one specific embodiment, the displacement component 22 is a hydraulic cylinder.

[0072] The second position sensor 14 is disposed on the worktable 1. Exemplarily, the second position sensor 14 is disposed on the first fixed frame 60 so as to directly monitor the vertical displacement of the upper mold 20 in the up-down direction.

[0073] In a specific application scenario, the first position sensor 13 is configured with a first threshold and a second threshold, and the second position sensor 14 is configured with a third threshold and a fourth threshold.

[0074] When the distance between the lower mold 21 and the first position sensor 13 reaches a first threshold preset by the first position sensor 13, the first position sensor 13 sends a signal to control the drive source 41 to stop working. At this time, the lower mold 21 is located directly below the upper mold 20 (i.e., molding station 11). Thus, the displacement component 22 drives the upper mold 20 to move downward, and when the distance between the upper mold 20 and the second position sensor 14 reaches a third threshold preset by the second position sensor 14, it indicates that the upper mold 20 has moved to the preset mold closing position, and the upper mold 20 is at least partially embedded in the molding cavity 210, thereby pressing and molding the fluororubber material.

[0075] At this time, pressure can be maintained for a certain period of time or the mold can be opened directly according to the actual application scenario. When the displacement component 22 drives the upper mold 20 to move upward, until the distance between the upper mold 20 and the second position sensor 14 reaches the fourth threshold preset by the second position sensor 14, the second position sensor 14 sends a signal to control the displacement component 22 to stop working, thus leaving enough space for the movement of the lower mold 21.

[0076] The second position sensor 14 can also be communicatively connected to the drive source 41, so that the second position sensor 14 can control the drive rod 40 to drive the lower mold 21 to move in the opposite direction. When the distance between the lower mold 21 and the first position sensor 13 reaches the second threshold of the first position sensor 13, the drive rod 40 stops driving the lower mold 21, at which time the lower mold 21 is located at the demolding station.

[0077] The lifting component 51 drives the top plate 50 to rise, thereby ejecting the fluororubber product from the molding cavity 210, making it easier for workers to collect the fluororubber product. After collection, the lifting component 51 drives the top plate 50 to descend to its reset position, and the drive rod 40 drives the lower mold 21 to move.

[0078] Of course, if the demolding station and the injection station 10 are not co-located, that is, when the injection station 10, the molding station 11, and the demolding station are arranged independently, the first position sensor 13 can also be set with a fifth threshold corresponding to the injection station 10. This allows the lower mold 21 to return to the injection station 10 located by the fifth threshold after demolding is completed, and start the next work cycle.

[0079] The control system further includes a controller 7 that is communicatively connected to one or more of the aforementioned weight sensor 34, first position sensor 13, and second position sensor 14. The controller 7 is located on the workbench 1 and is equipped with operation buttons and operation indicator lights for controlling the operation of the device.

[0080] For example, when the weight of the fluororubber compound in storage tank 3 reaches the preset value of weight sensor 34, the corresponding operating light will illuminate to indicate that the status is "preheating". Similarly, other statuses such as "mold closing", "mold demolding", "material injection", and "equipment malfunction" can be displayed by indicator lights of different colors to facilitate the monitoring of equipment operation status by the staff.

[0081] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
