Description

Technical Field

[0001] This invention relates to the field of mold cooling technology, specifically a quick-connect cooling device for large interior molds. Background Technology

[0002] The quick-connect cooling system for large interior molds is a modular and rapid water circuit docking system specifically designed for large automotive interior injection molds. It uses standardized quick connectors (corresponding to quick-connect strips in this article, and will be referred to as quick-connect strips in the following text) in conjunction with integrated water distribution blocks (corresponding to water distribution blocks in this article, and will be referred to as water distribution blocks in the following text) to replace the traditional single-pipe threaded connection, enabling one-click plugging and unplugging of the entire liquid circuit, making it more convenient.

[0003] The existing water distribution drain is fixed in the mold end and connected to the cooling circuit in the mold through multiple pipes. The quick-connect plug is connected to the existing external mold temperature controller for pumping in coolant and pumping out high-temperature liquid. During use, the quick-connect plug is mainly manually held and docked with the water distribution drain. Then, the operator manually rotates the crank handle on the quick-connect plug to switch the two working states, so that the cooling circuit can be switched between locked state, water inlet state, water outlet state, and water outlet state.

[0004] The existing quick-connect cooling process has the following problems: During mold use, quick-connect cooling is frequently required, necessitating repeated connection actions between the quick-connect strip and the water distribution strip. Currently, the connection process mainly relies on manual visual inspection and hand-held connection, with single-point locking at the center using a threaded locking method. This connection method is inefficient and exacerbates component wear after frequent connection, potentially affecting the final sealing performance. Secondly, the cooling process requires manual operation of the handle, which causes overall shaking. The single-point locking method cannot ensure the stability of the overall connection, and wear after long-term connection reduces the locking effect, thus affecting the overall sealing performance. Summary of the Invention

[0005] Therefore, it is necessary to provide a quick-connect cooling device for large interior molds, which aims to solve the problems of the prior art.

[0006] This application provides a quick-connect cooling device for a large interior mold, which is fixedly installed on the water collection plate at the mold end, including: a water distribution bar, wherein the water distribution bar is fixedly installed on the front end face of the mold end, and a quick-connect bar is installed on the front side of the water distribution bar.

[0010] The external locking assembly includes an operating frame disposed on both sides of the quick-connect strip and a connecting frame disposed on both sides of the water distribution strip. A locking frame between the water distribution strip and the quick-connect strip is formed by locking the operating frame and the connecting frame.

[0013] According to an advantageous embodiment, the front side of the mating sleeve, the rear side of the mating hole, the rear side of the mating seat, the first extrusion ring, and the second extrusion ring are all chamfered.

[0014] The quick-connect strip has guide holes corresponding to the guide posts.

[0015] According to an advantageous embodiment, the rear side of the operating pile and the front side of the central groove are both chamfered, and two centrally symmetrical spiral grooves are formed on the operating pile, with the rear side of the spiral grooves extending to the rear end face of the operating pile.

[0018] According to an advantageous embodiment, both operating frames are hinged to the left and right sides of the quick-connect strip, and two horizontally oriented locking rods are slidably arranged on the water distribution strip, with both locking rods penetrating into the central groove.

[0019] The operating stake has a self-locking groove that engages with two locking rods. When the operating handle is rotated from horizontal to a set oblique position, the docking seat is engaged in the docking groove, the fixed stake moves to the foremost side of the spiral groove, and the self-locking groove rotates to a horizontal position and is opposite to the locking rod.

[0020] The connecting frame is rotatably positioned at the end of the locking rod away from the water distribution drain, and the rearward movement of the operating frame causes the locking rod to insert into the self-locking groove.

In summary, the overall sealing performance and docking stability are improved. Attached Figure Description

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, a quick-connect cooling device for a large interior mold is fixedly installed on the water collection plate (hereinafter referred to as mold end 7) at the mold end 7, including: a water distribution drain 1, the water distribution drain 1 is fixedly installed on the front end face of the mold end 7, the water distribution drain 1 is connected to the inner channel of the mold end 7 through multiple pipes, and a quick-connect strip 2 is installed on the front side of the water distribution drain 1, the quick-connect strip 2 is connected to the mold temperature controller (not shown in the figure) through two main pipes.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the front end face of the water distribution drain 1 is provided with a docking groove 10, the rear end face of the quick-connect plug 2 is fixedly provided with a docking seat 20, the inner wall of the docking groove 10 is fixedly provided with docking sleeves 11 that correspond one-to-one with the pipes and are distributed circumferentially, the rear end face of the docking seat 20 is provided with docking holes 21 that correspond one-to-one with the docking sleeves 11, and the water distribution drain 1 and the quick-connect plug 2 are jointly provided with an inner and outer sealing assembly 3.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the front end face of the water distribution drain 1 is fixedly provided with four guide columns 4 arranged in a matrix and extending forward and backward along their axes.

[0037] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the quick-connect strip 2 is provided with an inner locking component 5 in the middle, and the water distribution strip 1 and the quick-connect strip 2 are provided with outer locking components 6 on both sides. The inner locking component 5 includes an operating stake 50. The operating stake 50, which extends forward and backward along the axis, is rotatably passed through the central area of ​​the quick-connect strip 2. A central groove 51 is provided through the water distribution strip 1. By inserting the operating stake 50 into the central groove 51, not only is the docking of the water distribution strip 1 and the quick-connect strip 2 guided, but the water distribution strip 1 and the quick-connect strip 2 are also locked by rotating the operating stake 50.

[0038] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the external locking assembly 6 includes an operating frame 60 disposed on both sides of the quick-connect strip 2 and a connecting frame 61 disposed on both sides of the water distribution strip 1. A locking frame between the water distribution strip 1 and the quick-connect strip 2 is formed by the locking steps between the operating frame 60 and the connecting frame 61.

[0039] Additional explanations are needed regarding the quick-connect and cooling operation steps: multiple pipes in the water distribution duct 1 are divided into inlet and outlet pipes, which correspond to the two main pipes on the quick-connect duct 2, thereby controlling the cooling circuit through an external mold temperature controller. In addition, a crank handle is installed on top of the quick-connect duct 2 to switch the cooling operation status. The cooling operation is performed manually by cranking the handle. The crank handle is an existing mature technology and is therefore not shown in the figure. Furthermore, operating the crank handle will cause the quick-connect duct 2 and the water distribution duct 1 to shake.

[0040] The operator manually holds the operating frame 60 and moves the quick-connect strip 2 so that the guide post 4 passes through the quick-connect strip 2, guiding the subsequent precise docking process (so that the operating post 50 and the center groove 51 are aligned front to back, and the docking sleeve 11 and the docking hole 21 are aligned front to back). This reduces excessive wear on components caused by manual docking and improves the overall docking accuracy and sealing. Then, the operator continuously pushes the quick-connect strip 2 backward so that the operating post 50 is engaged in the center groove 51. This completes the manual pushing step. At this point, the quick-connect strip 2 and the water distribution strip 1 are initially closed, that is, the docking seat 20 is initially engaged in the docking groove 10, and the docking sleeve 11 is initially engaged in the corresponding docking hole 21. Subsequently, the operator manually rotates the operating post 50 so that the quick-connect strip 2 and the water distribution strip 1 are completely closed and internally locked. At the same time, after this step is completed, the docking seat 20 is fully engaged in the docking groove 10, and the docking sleeve 11 is engaged in the corresponding docking hole 21. The mating holes 21 are fitted together front and back, forming an inner sealing ring for each pipe at the mating holes 21, while an overall outer sealing ring is formed at the mating seat 20. The internal and external sealing improves the overall sealing effect after mating. Then, the operating frame 60 is connected to the connecting frame 61, and the two are fixed as a whole. The operating frame 60 is pushed backward by hand to completely lock the operating stake 50 in the front-back direction, thus forming a locking frame with the operating frame 60, connecting frame 61 and operating stake 50 as a whole. This improves the stability of the quick-connect strip 2 and the water distribution strip 1 during cooling operations and the sealing effect of their mating. It should be further noted that the stability of the mating and operation processes is improved by the four guide pillars 4, and in conjunction with the internal and external locking process, the impact of shaking during operation on the connection effect is reduced, avoiding leakage problems caused by shaking operation.

[0041] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the inner and outer sealing assembly 3 includes an inner annular groove 30. The mating groove 10 is provided with an inner annular groove 30 corresponding to the mating sleeve 11. An extrusion ring 31 is fixedly provided on the inner wall of the inner annular groove 30. A rubber ring 32 corresponding to the mating hole 21 is fixedly provided on the rear end face of the mating seat 20. The axis of the inner annular groove 30, the axis of the rubber ring 32 and the axis of the mating sleeve 11 are collinear.

[0042] The inner and outer sealing assembly 3 also includes an outer annular groove. The circumferential surface of the mating seat 20 is provided with an outer annular groove. A rubber ring 34 is installed in the outer annular groove. A compression ring 35 is fixedly provided on the circumferential inner wall of the mating groove 10.

[0043] The front side of the mating sleeve 11, the rear side of the mating hole 21, the rear side of the mating seat 20, the compression ring 31 and the compression ring 35 are all chamfered.

[0044] The quick-connect strip 2 has a guide hole 40 corresponding to the guide post 4, and the rear side of the guide hole 40 is chamfered.

[0045] During the docking process between quick-connect strip 2 and water distribution strip 1, the quick-connect strip 2 is manually held and the guide posts 4 are aligned with the corresponding guide holes 40. This allows the quick-connect strip 2 to be docked onto the four guide posts 4. At this time, the quick-connect strip 2 and water distribution strip 1 are directly opposite each other, guiding the docking process of the subsequent docking seat 20 and docking groove 10, as well as the docking process of the docking sleeve 11 and docking hole 21. At the same time, the four guide posts 4 serve as the main force-bearing points during the docking process, improving the accuracy of the docking process and the stability of the operation.

[0046] During the process of connecting and locking the quick-connect strip 2 and the water distribution strip 1, the connecting sleeve 11 gradually engages into the corresponding connecting hole 21, and the rubber ring 32 enters the corresponding inner annular groove 30. The compression ring 31 compresses the rubber ring 32, causing it to deform, thus filling the inner annular groove 30 with the rubber ring 32, forming an inner sealing ring for a single connecting sleeve 11 and connecting hole 21, thereby forming multiple inner sealing rings for the connecting sleeve 11. Next, the connecting seat 20 drives the rubber ring 34 to move synchronously until it contacts the compression ring 35. The compression ring 35 compresses the rubber ring 34 and causes it to deform. Through the deformation of the rubber ring 34, an outer sealing ring is formed in the connecting groove 10. (See reference...) Figure 8 In summary, by using multiple inner and outer sealing rings to form a sealing environment, the overall sealing effect after docking is improved, and the impact of wear caused by repeated docking operations on the sealing performance is reduced.

[0047] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, an operating handle is fixedly installed on the front side of the operating pile 50. In the initial state, the operating handle is horizontal. The rear side of the operating pile 50 and the front side of the central groove 51 are both chamfered. Two centrally symmetrical spiral grooves 52 are opened on the operating pile 50. The rear side of the spiral grooves 52 extends to the rear end face of the operating pile 50.

[0048] Two symmetrical fixed piles 53 are fixedly installed on the inner wall of the central groove 51. The vertical end face of the fixed pile 53 is chamfered and corresponds to the spiral groove 52. As the operating pile 50 rotates, the fixed pile 53 moves relative to each other from back to front along the spiral groove 52, and the docking seat 20 gradually gets into the docking groove 10.

[0049] The operating pile 50 is fitted with a rubber ring 3 54 near the docking seat 20. The rear side of the rubber ring 3 54 is chamfered and fits into the chamfered area of ​​the front side of the central groove 51.

[0050] When quick-connect strip 2 and water distribution strip 1 are connected, the operating stake 50 enters the central groove 51, and the rear end opening of the spiral groove 52 is aligned with the corresponding fixed stake 53, with the fixed stake 53 located at the rear end opening of the spiral groove 52. At this time, quick-connect strip 2 and water distribution strip 1 are initially connected, that is, the connecting sleeve 11 is initially inserted into the connecting hole 21 and the connecting seat 20 is inserted into the connecting groove 10. At this time, the operator rotates the operating handle to drive the operating stake 50 to rotate synchronously. During this process, through the threaded engagement between the spiral groove 52 and the fixed stake 53, quick-connect strip 2 and water distribution strip 1 are completely connected and joined together during the rotation of the operating stake 50. The initial center locking between quick-connect strip 2 and water distribution strip 1 is completed through the threaded engagement between the two, thus completing the quick connection step of quick-connect strip 2.

[0051] During the above process, the docking seat 20 presses the rubber ring 54 against the inner wall of the docking groove 10, and makes the rubber ring 54 located in the peripheral area of ​​the front opening of the central groove 51. As the docking seat 20 fully penetrates into the docking groove 10, the rubber ring 54 deforms and fills the area between the operating pile 50 and the central groove 51, forming an internal seal for the area of ​​the central groove 51. Together with the inner and outer sealing components 3, it ensures the sealing performance of the overall circuit after quick connection.

[0052] like Figure 5 , Figure 6 and Figure 7 As shown, the two operating frames 60 are hinged to the left and right sides of the quick-connect strip 2. Two horizontally oriented locking rods 62 are slidably mounted on the water distribution strip 1. The opposing surfaces of the two locking rods 62 are chamfered and both penetrate into the central groove 51.

[0053] The operating stake 50 has a self-locking groove 63 that engages with two locking rods 62. Both ends of the self-locking groove 63 are chamfered. When the operating handle is rotated from horizontal to the set oblique state, the docking seat 20 is inserted into the docking groove 10, the fixed stake 53 moves to the foremost side of the spiral groove 52, and the self-locking groove 63 rotates to the horizontal orientation and is opposite to the locking rod 62.

[0054] The connecting frame 61 is rotatably mounted at the end of the locking rod 62 away from the water distribution drain 1. The operation frame 60 moves backward, causing the operation frame 60 to push the connecting frame 61 and the locking rod 62, and the locking rod 62 is inserted into the self-locking groove 63.

[0055] The connecting frame 61 is slidably fitted with a threaded rod 64, and a screw cap 65 is threadedly fitted at the upper end of the threaded rod 64. The operating frame 60 is provided with a slot 66 that mates with the threaded rod 64.

[0056] In order to limit the threaded rod 64 to be within a set height before docking, a limiting ring 67 is fixedly sleeved on the threaded rod 64. The limiting ring 67 is located between the middle of the connecting frame 61 and the lower end of the threaded rod 64. The rotating cap 65 is located above the operating frame 60. When the threaded rod 64 is inserted into the slot 66, the connecting frame 61 and the operating frame 60 are locked together by rotating the rotating cap 65.

[0057] During the quick-connection process, the operator can manually use the operating frame 60 to drive the quick-connect strip 2 for docking, improving the ease of operation. After the quick-connect strip 2 is initially inserted into the water distribution strip 1, the operator inserts the threaded rod 64 into the corresponding slot 66 and tightens the cap 65 to fix the operating frame 60 and the connecting frame 61 on the same side as a whole. At this time, the quick-connect strip 2 and the water distribution strip 1 are fully docked and the self-locking groove 63 has rotated from a vertical state to a horizontal state. Subsequently, the operator continues to push the operating frame 60 backward. The operating frame 60 pushes the corresponding locking rod 62 to move through the connecting frame 61, so that both locking rods 62 move and lock into the self-locking groove 63, thereby locking the operating post 50 in the front-back direction and circumferential direction. The operating post 50, locking rod 62, operating frame 60 and connecting frame 61 together form a locking frame. Therefore, the internal locking between the inner operating post 50 and the fixed post 53, combined with the above-mentioned external locking, improves the stability of the quick-connect strip 2 and the water distribution strip 1 after docking, avoiding the problem of shaking during the cooling operation affecting the quick-connection effect.

[0058] It should be further explained that: Existing technology uses a single-locking mode at the center position for the quick-connect locking of quick-connect strip 2 and water distribution strip 1. During the connection process, the docking of quick-connect strip 2 and water distribution strip 1 requires manual visual adjustment, which can easily exacerbate wear in the docking area due to lack of guidance, thus affecting the final sealing performance. Furthermore, during cooling operations after quick connection, manual operation can cause quick-connect strip 2 to wobble to a certain extent. The single-point locking mode cannot ensure stability after docking, easily leading to seal defects that affect cooling operations. This technical solution adds internal and external sealing components 3, guide posts 4, and an internal lock. The fixed component 5 and the external locking component 6 firstly guide the docking process through four guide pillars 4, thereby improving the docking stability during operation and shaking. Subsequently, the internal and external seals formed by the internal and external sealing components 3 ensure the overall sealing performance during shaking operation. Secondly, the internal lock first locks the quick-connect state and forms a self-locking state through the external lock. Thus, the two work together to ensure the stability and sealing performance of the connection state after quick-connection. Furthermore, the ease of operation is improved by changing the operation method. In addition, the added mechanical parts are all existing conventional parts, which can be used for a long time after a single installation. In summary, this technical solution is a specific improvement made entirely based on the defects of existing technology and to solve these defects.
