Description

Technical Field

[0001] This utility model relates to the field of plastic part molding technology, and in particular to a mold assembly for adjusting the volume of a water chamber. Background Technology

[0002] The water chamber of an automotive radiator is a thin-walled injection-molded part that is prone to shrinkage during cooling, resulting in a reduction in cavity volume. Therefore, a specific mold is needed to shape and adjust it during cooling to ensure the qualified rate of its cavity volume. Chinese Patent No. CN216373233U discloses an automotive water chamber shaping device. The device includes a mounting frame, a shaping mold for mounting the water chamber on the mounting frame, and a cylinder assembly set on the mounting frame and able to extend downward to press the water chamber onto the shaping mold. The shaping mold has fixing buckles at both ends, and the two ends of the fixing buckles are fixedly connected to the mounting frame by screws. The middle of the fixing buckle has two screws that pass through the fixing buckle and connect to the shaping mold.

[0003] When the aforementioned mold is installed on the mounting frame, the fixing buckles at both ends of the mold must be fully locked, and all eight screws must be tightened to prevent the mold from shifting during use. When changing to other models of molds, the four screws connected to the mold must be removed, and at least one fixing buckle must be removed before the mold can be taken out, which means at least six screws must be removed. After the new mold is placed in the installation position, the fixing buckle and six screws are then installed. The process of removing and installing multiple screws is time-consuming. Therefore, there is room for improvement in the existing installation method of the water chamber volume adjustment mold. Utility Model Content

[0004] To address the drawback of inconvenient disassembly and assembly of existing water chamber volume adjustment molds, the purpose of this invention is to provide a water chamber volume change adjustment mold assembly that is easier to disassemble and assemble.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A water chamber volume change adjustment mold assembly includes a shaping mold and a mounting frame for mounting the shaping mold. A locking component is horizontally slidably disposed on the mounting frame. Both ends of the shaping mold are respectively provided with a locking structure for the locking component to be partially engaged and able to move vertically, and an adjustment component for connecting the locking component and driving it to move upward after the locking component is engaged with the locking structure. The locking component passes through the mounting frame and when it moves upward, its end abuts against the side of the mounting frame opposite to the shaping mold.

[0007] Using the above solution, the locking component in this solution is equivalent to the fixing buckle in the prior art. In the prior art, each fixing buckle needs to be fixed to the mounting bracket with two screws. However, the locking component in this solution only needs to slide and snap into the snap-fit ​​structure to be fully connected to the pre-positioned part of the shaping mold. Moreover, the gap between the locking component and the snap-fit ​​structure makes it easier to achieve snap-fit ​​and disengagement. In the prior art, the connection between the shaping mold and the fixing buckle requires tightening four screws at both ends of the shaping mold. However, in this solution, it is only necessary to operate two adjusting components to connect with and adjust the locking component to drive the locking component to cooperate with the shaping mold to clamp the mounting bracket, thereby achieving fixation. Therefore, the connection method between the shaping mold and the mounting bracket in this solution is easier to install and disassemble than the prior art.

[0008] Preferably, the adjusting component is elastically telescopic relative to the shaping mold, automatically moving away from the locking component when the adjusting component is not in contact with the locking component, and moving closer to the locking component when the adjusting component is under pressure.

[0009] Preferably, the shaping mold has a vertical through-hole for the installation of the adjusting component, and a first elastic element is provided in the mounting hole to drive the adjusting component away from the locking component.

[0010] In this scheme, the adjusting component is normally driven away from the locking component by the first elastic element, and the blocking component can always limit the adjusting component within the mounting hole. One function of this design is to avoid interference from the adjusting component when the locking component slides into and out of the locking structure. When the adjusting component is connected to the locking component, the second function is that when the adjusting component and the locking component are not aligned and need to be recalibrated, simply loosen the adjusting component, and after adjusting the position of the locking component, press the adjusting component down again. Therefore, this design simplifies the operation of connecting the locking component with the shaping mold and the adjusting component.

[0011] Preferably, the forming mold is provided with a limiting structure for limiting the maximum and minimum extension stroke of the adjusting component. The limiting structure includes a stepped surface protruding into the mounting hole to limit the downward movement of the adjusting component and a blocking member to limit the adjusting component from being driven out of the mounting hole by the first elastic member.

[0012] Preferably, a receiving groove is provided on the step surface, and the first elastic element includes springs at both ends that elastically abut against the bottom of the receiving groove and the adjusting component, respectively.

[0013] With the above solution, when the adjusting component is in the locked state, the spring is retracted in the receiving groove to prevent excessive compression of the spring due to the downward pressure when the adjusting component is locked, which could cause damage. When the adjusting component is not in contact with the locking component, the spring drives the adjusting component away from the locking component. In order to prevent the spring from directly popping the adjusting component out of the mounting hole, this solution provides a blocking component in the mounting hole to limit the maximum extension and retraction stroke of the adjusting component.

[0014] Preferably, the blocking member includes an annular groove formed near the opening of the mounting hole and a retaining spring disposed within the annular groove, which abuts against the retaining spring when the adjusting member moves upward.

[0015] Using the above solution, the retaining ring is a standard part. You only need to select a model with an inner diameter smaller than the mounting hole diameter to purchase and use. The end face of the retaining ring can effectively block the movement of the adjusting component. When installing the adjusting component, the operator only needs to install the spring, adjusting component and retaining ring in sequence to complete the assembly. The operation process is simple and easy to understand.

[0016] Preferably, the adjusting component includes an adjusting bolt disposed in the mounting hole, and the end of the locking component is provided with a threaded hole for connection when it is facing the adjusting bolt.

[0017] Using the above scheme, the adjusting bolt is used to connect the locking component to form a whole. The first elastic element can then drive the locking component to rise and abut against the mounting bracket through the adjusting bolt. At this time, it is only necessary to tighten the adjusting bolt until it abuts against the step surface to form a fixed structure.

[0018] Preferably, the snap-fit ​​structure includes snap-fit ​​grooves at both ends of the forming mold and a sliding groove at the bottom of the forming mold that connects the snap-fit ​​grooves and the snap-fit ​​groove openings. The locking component includes a rod that passes through the mounting bracket, a snap-fit ​​end at one end of the rod for sliding and snapping into the snap-fit ​​groove, and an abutment end at the other end of the rod for abutting against the mounting bracket.

[0019] Using the above solution, the locking component can be hung on the mounting bracket or in the slot after being snapped into it. When it is installed in the mold but not connected to the adjustment component, it does not need to be supported by hand. When it is removed, it does not need to be stored, which is very convenient.

[0020] This utility model, by adopting the above technical solutions, has significant technical advantages: the locking component in this solution is equivalent to the fixing buckle in the prior art. In the prior art, each fixing buckle needs to be fixed to the mounting bracket with two screws, while the locking component only needs to slide and snap into the snap-fit ​​structure to be fully connected to the pre-positioned part of the shaping mold. Moreover, the gap between the locking component and the snap-fit ​​structure makes it easier to achieve snap-fit ​​and disengagement. In the prior art, the connection between the shaping mold and the fixing buckle requires tightening four screws at both ends of the shaping mold, while in this solution, it is only necessary to operate two adjusting components to connect with and adjust the locking component to drive the locking component to cooperate with the shaping mold to clamp the mounting bracket, thereby achieving fixation. Therefore, the connection method between the shaping mold and the mounting bracket in this solution is easier to install and disassemble than the prior art. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] A water chamber volume change adjustment mold assembly, according to Figure 1 , 2 As shown, it includes a mounting frame 2, on which a shaping mold 1 for installing a water chamber is provided. A locking component is horizontally slidable on the mounting frame 2. Both ends of the shaping mold 1 are respectively provided with snap-fit ​​structures. Figure 3As shown, in this embodiment, the snap-fit ​​structure includes snap-fit ​​grooves 101 at both ends of the shaping mold 1, and a sliding groove 102 at the bottom of the shaping mold 1 that connects the snap-fit ​​grooves 101 and the openings of the snap-fit ​​grooves 101. The locking component includes a rod that passes through the mounting bracket 2. One end of the rod is provided with a snap-fit ​​end for sliding and snapping into the snap-fit ​​groove 101. The snap-fit ​​end is detachably connected to the rod. The other end of the rod is provided with an abutment end for abutting against the mounting bracket 2. In this embodiment, the locking component includes a T-shaped screw. 3 and a nut 4 screwed to the end of the T-screw 3. The T-screw is equivalent to the combination of the rod body and the abutment end, and the nut 4 is equivalent to the snap-fit ​​end. The mounting bracket 2 has a through groove 201 for the rod body to pass through and slide horizontally. Under normal conditions, the T-screw 3 and the nut 4 can move vertically in the snap-fit ​​groove 101. The base 301 of the T-screw 3 is equivalent to the abutment end. When the T-screw 3 moves upward, the base 301 can abut against the mounting bracket 2 and form a cooperation with the shaping mold 1 to clamp the mounting bracket 2.

[0032] The forming mold 1 is equipped with an adjusting component. When the T-screw 3 is engaged in the slot 101, the adjusting component can connect to the T-screw 3 and drive it upward through adjustment. Figure 3 , 6 As shown in Figure 7, in this embodiment, the adjusting component includes an adjusting bolt 5 vertically arranged inside the shaping mold 1. The end of the T-shaped screw 3 is provided with a threaded hole 6 for connecting the adjusting bolt 5. The shaping mold 1 is provided with a mounting hole 7 for installing the adjusting bolt 5. The mounting hole 7 is provided with a stepped surface 8 for the adjusting bolt 5 to abut. When the adjusting bolt 5 is connected to the T-shaped screw 3, it can abut against the stepped surface 8. During the tightening process, the distance between the shaping mold 1 and the base 301 of the T-shaped screw 3 is gradually reduced to clamp the mounting bracket 2. In this embodiment, when the T-shaped screw 3 slides to the end of the rod body abutting against the slide groove 102, the threaded hole 6 on the T-shaped screw 3 is aligned with the adjusting bolt 5. When the adjusting bolt 5 locks the T-shaped screw 3, a gap of 1~2mm is left between the T-shaped screw 3 and the nut 4 and the inner wall of the top of the slot 101.

[0033] The adjusting component is elastically telescopic relative to the shaping mold 1. When the adjusting component is not in contact with the locking component, it automatically moves away from the locking component; when the adjusting component is under pressure, it moves closer to the locking component. A first elastic element is provided in the mounting hole 7 to drive the adjusting component to move upward. Figure 6 , 7 As shown, in this embodiment, a receiving groove 801 is provided on the end face of the step surface 8. The first elastic element includes a spring 9 whose two ends are elastically abutting between the bottom of the receiving groove 801 and the large end of the adjusting bolt 5, respectively. When the adjusting bolt 5 locks the T-shaped screw 3, the spring 9 is curled up in the receiving groove 801.

[0034] The shaping mold 1 is provided with a limiting structure to prevent the adjusting component from being driven out of the mounting hole 7 by the first elastic element, according to Figure 3 , 6 As shown in Figure 7, the component includes an annular groove 10 located near the opening of the mounting hole 7. A blocking member is provided in the annular groove 10. In this embodiment, the blocking member includes a retaining spring 11 provided in the annular groove 10. When the adjusting component moves upward, it elastically abuts against the end face of the retaining spring 11.

[0035] Based on the above structure, refer to Figures 1-7 It can be seen that the water chamber volume change adjustment mold in this embodiment consists of three main parts: mounting frame 2, shaping mold 1, and installation components. The installation process of the three parts is as follows:

[0036] First, place the bottom of the shaping mold 1 directly above the through groove 201 and place it on the mounting bracket 2 to achieve initial alignment of the slot 101 and the T-screw 3. Next, slide the two locking components to the opening near the slot 101 and observe whether the current height of the nut 4 can enter the slot 101. If not, tighten the nut 4 to be slightly higher than the inner wall of the bottom of the slot 101. Then, slide the T-screw 3 and the nut 4 into the slot 101 and make the T-screw 3 abut against the end of the slide groove 102. Next, tighten the screw by pressing the adjusting bolt 5 downward with a screwdriver until it contacts the T-screw 3. Then, rotate the adjusting bolt 5 to engage with the threaded hole 6 on the T-screw 3, driving the T-screw 3 and the nut 4 upward until the base 301 abuts against the mounting bracket 2. Finally, tighten the adjusting bolt 5 to fix the shaping mold 1 on the mounting bracket 2.

[0037] In this embodiment, a water chamber volume change adjustment mold has a locking component that can be fully connected to the pre-positioned mold 1 simply by sliding and snapping into the snap-fit ​​structure. The gap between the locking component and the snap-fit ​​structure makes it easier to snap and detach. Then, by operating the two adjustment components to connect with and adjust the locking component, the locking component can be driven to cooperate with the mold 1 to clamp the mounting frame 2, thereby achieving fixation. Therefore, the connection method between the mold 1 and the mounting frame 2 in this solution is easier to install and disassemble than the prior art.

[0038] 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.
