Description

Technical Field

[0001] This utility model relates to the field of foamed rotating hub technology, specifically to an ice-making door foamed rotating hub assembly mechanism. Background Technology

[0002] Currently, in the ice-making industry, refrigerator doors are manufactured by placing the door liner and door shell into a door foaming mold, pouring foaming material between them, and then closing the mold to perform the foaming process. The door foaming mold itself lacks a power mechanism and needs to be placed in a fixture to complete the production process. The door foaming mold consists of two main parts: an upper mold and a lower mold. The upper mold is fixed to the upper template of the foaming line fixture using front and rear side strips, and the lower mold is also fixed to the lower template of the foaming line fixture using front and rear side strips. The foaming line fixture performs a large-angle opening and closing motion, which in turn drives the door foaming mold to open and close, thus performing the foaming operation on the door.

[0003] In existing foaming drum upper and lower mold frames, multiple electronic locking modules are usually required for locking and positioning during mold assembly. Each locking module is independent of the others. If a set of locking modules is damaged, the upper and lower mold frames cannot be locked and fixed, requiring machine shutdown for inspection and affecting the normal operation of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide an ice-making door foaming hub assembly mechanism to solve the following technical problems:

[0005] In the existing foaming hub, the upper mold frame and lower mold frame are assembled in mold closing. Each electronic locking module is independent of the others. If any group is damaged, it will affect the normal mold closing assembly of the upper mold frame and the lower mold frame.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An ice-making door foaming hub assembly mechanism includes an upper mold frame and a lower mold frame, characterized in that one side of the upper mold frame is rotatably connected to the lower mold frame through a plurality of sets of hinged movable shafts, and the other side of the upper mold frame is locked to the lower mold frame through a locking module;

[0008] The locking module includes a first locking frame that is slidably arranged on one side of the upper mold frame. Several sets of locking plates are fixedly arranged at equal intervals on the side of the first locking frame away from the upper mold frame. Each locking plate is perpendicular to the first locking frame. A first locking block and a second locking block are fixedly arranged on the end of the locking plate near the side of the upper mold frame. A locking groove is formed between the first locking block and the second locking block.

[0009] Among them, a number of locking pins corresponding to the locking grooves are fixedly arranged on one side of the lower mold frame.

[0010] Preferably, a wedge-shaped protrusion is fixedly arranged on the side of the first locking block that is close to the second locking block. The wedge-shaped protrusion has a first inclined surface on the side of the second locking block that is close to the second locking block. The second locking block has a second inclined surface that is parallel to the first inclined surface on the side of the first locking block. The first inclined surface and the second inclined surface together form an inclined groove that is connected to the locking groove.

[0011] Preferably, the hinge movable shaft includes a guide shaft arranged on one side of the upper mold frame, and the end of the guide shaft away from the upper mold frame is rotatably connected to a limiting frame fixedly arranged on the upper mold frame.

[0012] Preferably, the guide shaft and the limiting frame are evenly distributed in four sets.

[0013] Preferably, an adjustment part is provided on one side of the upper mold frame, which is used to adjust the distance between the guide shaft and the lower mold frame.

[0014] Preferably, several sets of positioning seats are fixedly arranged on the side of the upper mold frame away from the first locking frame, and each guide shaft is slidably inserted into the positioning seat.

[0015] Preferably, a second locking frame is slidably arranged on the side of the upper mold frame away from the first locking frame, the second locking frame is slidably connected to the positioning seat, and the lifting part includes a guide groove opened on the second locking frame, the guide groove receiving the inclined limiting groove;

[0016] The limiting groove contains a limiting pin that is fixed to the guide shaft.

[0017] Preferably, the locking plates are arranged in four sets.

[0018] Preferably, each of the locking plates is connected and fixed by reinforcing ribs.

[0019] Preferably, the reinforcing rib is connected to the locking plate by bolts.

[0020] The beneficial effects of this utility model are:

[0021] (1) When locking and fixing the upper mold frame and the lower mold frame, the present invention first slides the first locking frame so that each locking plate and locking pin are in a misaligned state, and then slides the first locking frame back to reset so that the locking pin can be embedded in the locking groove, thereby achieving the locking effect. Only the sliding of the first locking frame needs to be adjusted to realize the mold closing and opening of the upper mold frame and the lower mold frame. Compared with the existing technology that uses several independent sets of electronic locking modules, the locking module of the present invention is an integrated structure with higher stability and synchronization and longer service life.

[0022] (2) During the mold assembly process, when the drive locking plate and the locking pin are misaligned, the locking pin first corresponds to the position of the inclined groove. As the drive first locking frame is reset and slides, the locking pin slides along the inclined groove. During the sliding process, the distance between the upper mold frame and the lower mold frame can be further reduced so that the tightness and sealing of the upper mold frame and the lower mold frame when they are molded are higher.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figure 1 As shown, this utility model is an ice-making door foaming hub assembly mechanism, including an upper mold frame 1 and a lower mold frame 2. One side of the upper mold frame 1 is rotatably connected to the lower mold frame 2 through several sets of hinged movable shafts, and the other side of the upper mold frame 1 is locked to the lower mold frame 2 through a locking module.

[0034] It should be noted that when the mold is closed, the upper mold frame 1 and the lower mold frame 2 are set in parallel relative to each other. When it is necessary to adjust the mold opening, first adjust the locking module to the open state, and then drive the lower mold frame 2 to deflect away from the upper mold frame 1 around the hinge axis.

[0035] Please see Figures 1-4 Specifically, the locking module includes a first locking frame 4 slidably arranged on one side of the upper mold frame 1. Several sets of locking plates 202 are fixedly arranged at equal intervals on the side of the first locking frame 4 away from the upper mold frame 1. Each locking plate 202 is perpendicular to the first locking frame 4. A first locking block 401 and a second locking block 402 are fixedly arranged on the end of the locking plate 202 near the side of the upper mold frame 1, respectively. A locking groove 406 is formed between the first locking block 401 and the second locking block 402. Several sets of locking pins 302 corresponding to the locking grooves 406 are fixedly arranged on one side of the lower mold frame 2.

[0036] It can be explained that when locking and fixing the upper mold frame 1 and the lower mold frame 2, in this embodiment, the first locking frame 4 is first slid to make each locking plate 202 and the locking pin 302 misaligned. Then, the first locking frame 4 is slid back to its original position so that the locking pin 302 can be embedded in the locking groove 406, thereby achieving the locking effect. In this embodiment, only the sliding of the first locking frame 4 needs to be adjusted to realize the mold closing and opening of the upper mold frame 1 and the lower mold frame 2. Compared with the existing technology that uses several independent sets of electronic locking modules, the locking module of this embodiment is an integrated structure, which has higher stability and synchronization and a longer service life.

[0037] In addition, the locking plates 202 in this embodiment are arranged in four sets, and the specific number of them is not limited, as long as the actual locking effect between the mold frame 1 and the lower mold frame 2 is met.

[0038] It should also be noted that when driving the first locking frame 4 to slide, a servo drive device such as a pneumatic cylinder or an electric cylinder can be used, and there is no restriction on the specific model, as long as it meets the actual needs of driving the first locking frame 4 to slide.

[0039] Example 2

[0040] Based on Example 1, please refer to Figure 4 and Figure 6 To improve the locking stability of the upper mold holder 1 and the lower mold holder 2, in this embodiment, a wedge-shaped protrusion 403 is fixedly arranged on the side of the first locking block 401 facing the second locking block 402. The wedge-shaped protrusion 403 has a first inclined surface 405 on the side facing the second locking block 402, and the second locking block 402 has a second inclined surface 404 parallel to the first inclined surface 405 on the side facing the first locking block 401. The first inclined surface 405 and the second inclined surface 404 together form a locking groove 406. The inclined groove 407 is used to explain that during the mold closing process of the upper mold frame 1 and the lower mold frame 2, when the driving locking plate 202 and the locking pin 302 are in a misaligned state, the locking pin 302 first corresponds to the position of the inclined groove 407. As the driving first locking frame 4 resets and slides, the locking pin 302 slides along the inclined groove 407. During the sliding process, the distance between the upper mold frame 1 and the lower mold frame 2 can be further reduced, so that the tightness and sealing of the upper mold frame 1 and the lower mold frame 2 when they are closed are higher.

[0041] In addition, in order to improve the stability of each locking plate 202, each locking plate 202 is connected and fixed by a reinforcing rib 203, and the reinforcing rib 203 is connected to the locking plate 202 by bolt fixing.

[0042] In this embodiment, please refer to Figures 1-2 The hinge axis includes a guide shaft 102 arranged on one side of the upper mold frame 1. The end of the guide shaft 102 away from the upper mold frame 1 is rotatably connected to a limiting frame 201 fixed on the upper mold frame 2. It can be explained that when the mold is opened, as the lower mold frame 2 deflects away from the upper mold frame 1, the lower mold frame 2 rotates around the guide shaft 102 through the limiting frame 201.

[0043] Specifically, in this embodiment, the guide shaft 102 and the limiting frame 201 are evenly distributed in four sets, and the specific number of them is not limited.

[0044] As a further solution in this embodiment, please refer to Figures 1-2 and Figure 5 When the locking pin 302 slides along the inclined groove 407, as the distance between the upper mold frame 1 and the lower mold frame 2 decreases, in order to avoid interference with the guide shaft 102 and the limiting frame 201, an adjustment part is provided on one side of the upper mold frame 1. The adjustment part is used to adjust the distance between the guide shaft 102 and the lower mold frame 2. It can be explained that as the distance between the upper mold frame 1 and the lower mold frame 2 decreases, in this embodiment, the guide shaft 102 can be adjusted to slide away from the lower mold frame 2 in sync through the adjustment part, so that the distance between the guide shaft 102 and the lower mold frame 2 also decreases in sync, thereby ensuring the consistency of the distance between the two sides of the upper mold frame 1 and the lower mold frame 2.

[0045] Specifically, several sets of positioning seats 101 are fixedly arranged on the side of the upper mold frame 1 away from the first locking frame 4, and each guide shaft 102 is slidably inserted into the positioning seat 101; specifically, when adjusting the position of the guide shaft 102, the guide shaft 102 can slide in the positioning seat 101 to improve the stability of the guide shaft 102 when sliding.

[0046] A second locking frame 3 is slidably arranged on the side of the upper mold frame 1 away from the first locking frame 4. The second locking frame 3 is slidably connected to the positioning seat 101. The lifting part includes a guide groove 301 opened on the second locking frame 3. The guide groove 301 is received by an inclined limiting groove 304. A limiting pin 303 fixed to the guide shaft 102 is slidably embedded in the limiting groove 304. Specifically, in the initial state, the limiting pin 303 is located at the end of the guide groove 301 away from the limiting groove 304. When the distance between the upper mold frame 1 and the lower mold frame 2 decreases, the second locking frame 3 can be slid synchronously. During the sliding process, the second locking frame 3 drives the limiting pin 303 to slide along the guide groove 301 towards the limiting groove 304. Then, the limiting pin 303 can synchronously drive the guide shaft 102 to slide away from the lower mold frame 2, so as to reduce the distance between the guide shaft 102 and the lower mold frame 2, so that the change in the distance between the two sides of the upper mold frame 1 and the lower mold frame 2 remains consistent.

[0047] Furthermore, in this embodiment, a pneumatic cylinder or an electric cylinder can be used to drive the second locking frame 3 to slide, and the signal of the specific servo drive device is not limited.
