Description

Technical Field

[0001] This utility model relates to the technical field of foaming molds, and in particular to a foaming mold for a vehicle refrigerator body. Background Technology

[0002] With the increasing popularity of car refrigerators, their appearance and performance directly influence users' vehicle choices. Therefore, the manufacturing quality of car refrigerators is a crucial factor for manufacturers. A car refrigerator consists of a body and a closable lid. The structure of the refrigerator body is typically as follows... Figure 6 As shown, it consists of a shell 21 and a foamed layer in the interlayer, which plays a key role in heat preservation and shock absorption.

[0003] However, current foaming molds for vehicle refrigerator bodies have the following problems: Currently, vehicle refrigerator bodies are mainly assembled structures, meaning that several single-panel side panels are formed through a foaming process and then assembled into a whole body. Vehicle refrigerator bodies produced in this way have poor insulation performance, and when installed in a car, gaps are easily created due to vibration, further weakening the insulation effect. Therefore, it is desirable to design the refrigerator body as a one-piece molded structure. However, a refrigerator body with a one-piece foamed layer has the following drawbacks: during the foaming process, the expansion force of the foaming material (such as polyurethane) directly acts on the inner and outer walls of the shell 21. Due to the lack of effective support structures on the inner and outer walls, the shell 21 deforms or even cracks, resulting in poor molding quality and low precision of the vehicle refrigerator body. Therefore, to solve the above problems, the vehicle refrigerator body foaming mold of this application is proposed. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] like Figures 1 to 3As shown, a foaming mold 10 for a vehicle refrigerator body includes a base 100, an inner clamping assembly 200, and an outer clamping assembly 300. The inner clamping assembly 200 includes an inner top plate 210, an inner clamping drive member 220, a push block 230, and four inner side plates 240. The inner top plate 210 is disposed on the base 100. The push block 230 is slidably disposed between the base 100 and the inner top plate 210 in a vertical direction. The inner clamping drive member 220 is disposed on the base 100, and its output shaft is connected to the push block 230. The four inner side plates 240 are slidably disposed on the base 100 around the push block 230, and all four inner side plates 240 are slidably connected to the push block 230. When the inner clamping drive member 220 drives the push block 230 to slide closer to the base 100, the push block 230 drives each inner side plate 240 away from each other to support the inner wall of the housing 21. Component 300 includes a cover plate 310, a cover-closing drive member 320, four enclosing drive members 330, and four outer side plates 340. The four outer side plates 340 are slidably / rotatably mounted on the base 100 and are located on the outer periphery of the inner clamping component 200. The four enclosing drive members 330 are all mounted on the base 100 and are connected to the outer side plates 340 respectively. The four enclosing drive members 330 are used to drive the four outer side plates 340 to move closer to each other to support the outer side wall of the housing 21. The cover plate 310 is rotatably mounted on one of the outer side plates 340. The cover-closing drive member 320 is mounted on the base 100 and its output shaft is connected to the cover plate 310. When the cover plate 310 is engaged with the four outer side plates 340, the cover plate 310 supports the top surface of the housing 21.

[0035] It should be noted that the housing 21 is placed on the base 100, so that the inner clamping assembly 200 is located inside the inner wall of the housing 21. The inner clamping drive 220 drives the push block 230 to move vertically along the base 100. In one embodiment, the inner clamping drive 220 is a cylinder. Further, the four surfaces of the push block 230 are designed with inclined surfaces, which are slidably connected to the four inner side plates 240. When the push block 230 is pressed down, the vertical force is converted into a horizontal component force through the mechanical decomposition of the inclined surfaces, forcing the four inner side plates 240 to expand radially outward synchronously and precisely abut against the inner wall of the housing 21. When the inner clamping drive 220 drives the push block 230 to rise, the push block 230 can drive the inner side plates 240 to move closer to each other, so that the inner side plates 240 release their support on the housing 21, allowing the housing 21 to be removed from the base 100. Furthermore, the four enclosing drive members 330 respectively control the four outer side plates 340 to slide or rotate along the base 100, so that the four outer side plates 340 can approach each other to enclose the inner clamping assembly 200 or move away from each other. When the four outer side plates 340 approach each other, the four outer side plates 340 can abut against the outer side wall of the housing 21. Furthermore, the cover plate 310 is rotatably mounted on the top of one of the outer side plates 340 by a pin, and the cover closing drive member 320 drives the cover plate 310 to rotate, so that the cover plate 310 can engage with or open with each of the outer side plates 340. In one embodiment, the cover closing drive member 320 and the enclosing drive member 330 are both cylinders. Thus, the function of the vehicle refrigerator body foaming mold 10 of this application is as follows: the lid-closing drive 320 drives the lid plate 310 to flip open; the four enclosing drive 330 respectively drive the four outer side plates 340 to move away from each other; the inner clamping drive 220 drives the push block 230 to rise in the vertical direction, so that the push block 230 drives each inner side plate 240 to move closer to each other; then the shell 21 is placed on the base 100; then the inner clamping drive 220 drives the four inner side plates 240 to move away from each other through the push block 230, so that the four inner side plates 240 support and fix the inner side wall of the shell 21; then the four enclosing drive 330 respectively drive the four outer side plates 340 to enclose each other, so that the four outer side plates 340 support the four outer side walls of the shell 21; finally, the lid-closing drive 320 drives the lid plate 310 to fasten with the four outer side plates 340, so that the lid plate 310 supports the top surface of the shell 21. In this way, the inner and outer walls of the shell 21 are supported and fixed. When the foam material is injected into the inner layer of the shell 21, the inner and outer walls of the shell 21 will not deform due to the expansion of the foam material, thus realizing the one-piece molding process and effectively improving the molding quality of the vehicle refrigerator body.

[0036] like Figure 1 As shown, in one embodiment, the base 100 includes a base plate 110 and a bottom plate 120. The bottom plate 120 is disposed on the base plate 110, the inner clamping component 200 is disposed on the bottom plate 120, and the four enclosing driving members 330 are all disposed on the base plate 110.

[0037] It should be noted that the base plate 120 is mounted parallel to the substrate 110, and there is a gap between the base plate 120 and the substrate 110. The inner top plate 210 is mounted on the base plate 120, and the inner clamping drive member 220 is mounted on the bottom of the base plate 120. The push block 230 is slidably mounted on the base plate 120 in the vertical direction, and the four inner side plates 240 are all located on the side of the base plate 120 away from the substrate 110. In this way, the housing 21 is placed on the base plate 120 for fixation. Furthermore, the four outer side plates 340 can be partially rotatably mounted on the base plate 120, or can be fully rotatably mounted on the base plate 120, or can be partially slidably mounted on the substrate 110, or can be fully slidably mounted on the substrate 110. For ease of description, this application will describe an embodiment in which three outer side plates 340 are rotatably mounted on the base plate 120 and one outer side plate 340 is slidably mounted on the substrate 110.

[0038] In one embodiment, one end of the outer side plate 340 is rotatably mounted on the base plate 120. Specifically, one end of the outer side plate 340 is rotatably connected to the edge of the base plate 120 via a pin.

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, the base 100 further includes a support plate 130, which is disposed on the base plate 110, and the outer side plate 340 is slidably disposed on the support plate 130 along the normal direction.

[0040] It should be noted that the support plate 130 is bolted to the base plate 110, and one side of the support plate 130 abuts against the end face of the base plate 120. One of the outer plates 340 slides relative to the support plate 130 along the normal direction of the support plate 130 via a guide post, so that the outer plate 340 can slide relative to the base plate 110 to move closer to or away from the inner clamping assembly 200.

[0041] like Figure 2 and Figure 5 As shown, in one embodiment, a core block 351 is slidably disposed along the normal direction on the side surface of the outer plate 340 near the inner clamping assembly 200, and a side insertion drive 352 is disposed on the side surface of the outer plate 340 away from the inner clamping assembly 200, and the output shaft of the side insertion drive 352 is connected to the core block 351.

[0042] It should be noted that when the housing 21 has a lateral cavity, in order to ensure that the inner wall of the cavity is supported and not deformed by the expansion of the foam material, a side insertion drive 352 is installed on the slidingly mounted outer side plate 340. In one embodiment, the side insertion drive 352 is a cylinder. The core block 351 is mounted on the output shaft of the side insertion drive 352, and the side insertion drive 352 drives the core block 351 to slide laterally relative to the outer side plate 340 to insert into the lateral inner cavity of the housing 21 for support and fixation.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, an inclined top block 361 is provided on the outer side plate 340, and an inclined pressure block 362 is provided on the cover plate 310. When the cover plate 310 is engaged with each outer side plate 340, the inclined pressure block 362 pushes the inclined top block 361.

[0044] It should be noted that, in order to ensure that the cover plate 310 can be accurately fastened to each of the outer side plates 340, an appropriate inclined top block 361 and an inclined pressure block 362 are provided. The inclined top block 361 and the inclined pressure block 362 are respectively provided with appropriate inclined surfaces. In this way, by using the pushing action of the inclined surfaces, the cover plate 310 can tighten the top of each of the outer side plates 340.

[0045] like Figure 1 As shown, in one embodiment, the outer fitting assembly 300 further includes a fastening post 371, a fastening block 372, and a fastening drive member 373. The fastening post 371 is disposed on the cover plate 310, the fastening block 372 is rotatably disposed on the outer side plate 340, and the fastening drive member 373 is disposed on the outer side plate 340. The output shaft of the fastening drive member 373 is connected to one end of the fastening block 372. When the fastening drive member 373 drives the fastening block 372 to rotate, the fastening block 372 engages with the fastening post 371.

[0046] It should be noted that this embodiment is designed to ensure that the cover plate 310 can be stably engaged with each of the outer side plates 340. Specifically, the fastening block 372 is rotatably mounted on the outer side plate 340 via a pin, and the fastening drive member 373 is mounted on the outer side plate 340. The output shaft of the fastening drive member 373 is rotatably connected to one end of the fastening block 372, and the other end of the fastening block 372 has a slot. In one embodiment, the fastening drive member 373 is a cylinder. Thus, the fastening block 372 is rotated by the fastening drive member 373, causing the slot to engage the fastening post 371, thereby ensuring that the cover plate 310 is stably engaged with each of the outer side plates 340.

[0047] like Figure 3 As shown, in one embodiment, the inner clamping assembly 200 further includes a plurality of guide posts 250, each guide post 250 being spaced apart on the base plate 120, the inner top plate 210 being disposed on the top of each guide post 250, and each guide post 250 having a push block 230 passing through it.

[0048] It should be noted that one end of each guide post 250 is fixedly mounted on the base plate 120, and the axis of each guide post 250 extends vertically, with a gap between each guide post 250. Each guide post 250 passes through the push block 230, allowing the push block 230 to slide along the axial direction of the guide post 250. In one embodiment, four guide posts 250 are provided.

[0049] like Figure 3 As shown, in one embodiment, an inclined T-block 261 is provided on the inner side plate 240, and an inclined T-groove 231 is provided on the push block 230. The inclined T-block 261 is adapted to slide within the inclined T-groove 231.

[0050] It should be noted that the cross-section of the inclined T-block 261 is T-shaped, and there is an angle between the inclined T-block 261 and the axis of the guide post 250. Similarly, the cross-section of the inclined T-slot 231 is also T-shaped, and there is an angle between the extension direction of the inclined T-slot 231 and the guide post 250. In this way, the inclined T-block 261 is fitted into the inclined T-slot 231. When the push block 230 moves up and down, through the decomposition of force, it can drive each inner side plate 240 to slide relative to the base plate 120 to move closer or further apart.

[0051] like Figure 3 As shown, in one embodiment, a plurality of protrusions 241 are provided on both sides of the inner side plate 240, such that a groove 242 is formed between any two adjacent protrusions 241. When the push block 230 drives each inner side plate 240 to move closer to each other, the protrusion 241 of any inner side plate 240 is adapted to be inserted into the groove 242 of the adjacent inner side plate 240.

[0052] It should be noted that, in order to ensure that the inner side plate 240 can stably push against the inner wall of the housing 21, that is, to ensure that the inner side plate 240 covers the inner wall of the housing 21 as much as possible, and to ensure that the inner side plates 240 can approach each other and close together, protrusions 241 distributed at intervals are provided on both sides of the inner side plate 240, such that the interval between any two adjacent protrusions 241 forms a groove 242. In this way, when the inner side plates 240 approach each other to close together, the protrusion 241 of one inner side plate 240 will fit into the groove 242 of the adjacent inner side plate 240, avoiding structural interference between the inner side plates 240.

[0053] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
