Description

Technical Field

[0001] This invention belongs to the field of freezer manufacturing technology, specifically relating to a foaming equipment for a vertical display freezer body that can be quickly changed. Background Technology

[0002] Vertical display refrigerators are devices used for refrigerating and displaying food, medicine, beverages, and other items. They are commonly used in shopping malls, supermarkets, convenience stores, and similar establishments. Figure 1 As shown, the common upright display refrigerator body 1 is as follows: Figure 1 As shown, the display cabinet includes a compressor area 11, a main body area 12, and a light box area 13 arranged sequentially from bottom to top. Some vertical display freezers do not have a light box area 13 on the top of the cabinet body 1. The main body area 12 is a receiving cavity with a front opening for storing items. The compressor area 11 is open from front to back and is used to arrange refrigeration equipment such as compressors. The light box area 13 is also open from front to back and is used to arrange equipment such as light boxes.

[0003] Currently, most existing upright display refrigerators are manufactured using linear foaming equipment, such as... Figure 2 As shown, the linear foaming equipment includes a main frame 2a, a moving frame 3a, a foaming mold 4a, and a foaming fixture; the moving frame 3a is connected to the main frame 2a and can be raised and lowered. The foaming fixture specifically includes a base plate 51a, a front baffle and a rear baffle arranged opposite each other, and a left side plate 52a and a right side plate 53a arranged opposite each other; the base plate 51a is connected to the moving frame 3a; the left side plate 52a and the right side plate 53a are respectively hinged to a left fixed plate 54a and a right fixed plate 55a, which are connected to the moving frame 3a; the front baffle and the rear baffle are respectively hinged to a front hanging plate and a rear hanging plate, which are suspended on the top frame 21a of the main frame 2a. The foaming mold 4a is suspended on the top frame 21a of the main frame 2a. During production, the vertical display refrigerator body to be foamed adopts a forward foaming method, that is, the main body area 12 is placed on the base plate 51a with the opening facing upward. The moving frame 3a drives the base plate 51a, the left side plate 52a, the right side plate 53a and the body to be foamed to rise until they are closed with the foaming mold 4a, the front baffle and the rear baffle. That is, the foaming mold 4a and the foaming fixture jointly hold the body to be foamed, and then foaming is carried out to obtain the foamed body 1. The foaming process dimensions of the body 1 are achieved through the cooperation between the various components of the foaming mold 4a and the foaming fixture.

[0004] However, the foaming mold 4a of the existing vertical display refrigerator cabinet body usually adopts multiple sets of molds to realize the foaming of the cabinet body 1; specifically, the main body area 12 of the cabinet body 1 adopts a main body mold, the press area 11 adopts a cabinet bottom plug mold, and the lamp box area 13 adopts a cabinet top plug mold; before the molds are closed, the cabinet bottom plug mold and the cabinet top plug mold are pre-inserted into the cabinet body to be foamed, that is, the main body mold, the cabinet bottom plug mold and the cabinet top plug mold are independent of each other and have no connection relationship; after the molds are closed, the front and rear baffles of the foaming clamp are respectively pressed against the outside of the cabinet bottom plug mold and the cabinet top plug mold, and multiple locking mechanisms 6a arranged on the top frame 21a of the main frame 2a are pressed against the left side plate 52a and the right side plate 53a from the left and right sides to realize the cooperation between the main body mold and the foaming clamp. As can be seen from the above, the foaming mold 4a of the existing vertical display refrigerator cabinet body and the components (such as the front baffle, the rear baffle, the left side plate 52a, the right side plate 53a and the bottom plate 51a, etc.) of the foaming clamp have no direct matching positioning mechanism, so when the model or size of the vertical display refrigerator cabinet body 1 changes and needs to be changed, the following disadvantages may occur:

[0005] 1) Each time the foaming mold 4a is replaced, the components of the foaming clamp and the related mechanisms need to be adjusted and positioned one by one based on the main body mold in the foaming mold 4a, such as the left side plate 52a, the right side plate 53a and the related positioning and locking mechanisms, and the new cabinet bottom plug mold and the cabinet top plug mold need to be pre-inserted into the cabinet body to be foamed and adjusted into position; it can be seen that the mold changing operation is complex and tedious, requires a high level of mold changing workers to complete, and has problems such as low mold changing efficiency and high labor intensity;

[0006] 2) Since the foaming mold 4a and the foaming clamp have no direct matching positioning mechanism, that is, they have no correlation, after the foaming mold 4a is changed and adjusted, multiple cabinet bodies need to be used for mold testing verification, the pass rate of the mold testing after the change is low, and the mold testing foaming cabinet body is easily scrapped due to quality problems, which is not suitable for small batch cabinet production of multiple models. SUMMARY

[0007] In view of the deficiencies in the related art, the present application provides a vertical display refrigerator cabinet body foaming equipment capable of rapid model change, aiming to reduce the difficulty of mold changing and improve the efficiency of mold changing and the pass rate of cabinet body model change.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] like Figures 3-7 As shown, this invention provides a quick-change vertical display refrigerator body foaming device, including a main frame 2, a moving frame, a foaming fixture, and a foaming mold 4. The foaming fixture includes a left side plate 31 and a right side plate 32 arranged opposite to each other. Multiple first positioning pins 311 are spaced apart along the front-back direction on the top surface of the left side plate 31, and multiple second positioning pins 321 are spaced apart along the front-back direction on the top surface of the right side plate 32. The multiple first positioning pins 311 and multiple second positioning pins 321 correspond one-to-one to form multiple pairs of positioning pin groups. The foaming mold 4 includes a main body fixing frame 41, a main body mold core 42, a bottom mold core 43, a top mold core 44, and multiple side plate positioning mechanisms 45. The main body mold core 42, the bottom mold core 43, and the top mold core 44 are all installed on the bottom surface of the main body fixing frame 41. The multiple side plate positioning mechanisms 45 are installed on the upper part of the main body fixing frame 41 and spaced apart along the front-back direction. Each side plate positioning mechanism 45 is located opposite a pair of positioning pin groups.

[0041] Furthermore, the positioning mechanism 45 on each side plate specifically includes a connecting plate 451 and two locking arms 452. The connecting plate 451 spans across the main body fixing frame 41 and is connected to the main body fixing frame 41; the two locking arms 452 are respectively connected to both ends of the bottom surface of the connecting plate 451 and are both suspended outside the main body fixing frame 41. The bottom surface of each locking arm 452 is recessed with a positioning hole 453 to be inserted and positioned with a pair of positioning pins on the foaming fixture. To further explain, during foaming production, the moving frame drives the left side plate 31 and the right side plate 32 to move upward until they are closed with the foaming mold 4. At this time, the positioning pins on the foaming fixture are inserted into the positioning holes 453 of the positioning mechanism 45 on the side plate, thereby realizing the matching and positioning of the foaming fixture and the foaming mold 4.

[0042] The above-mentioned schematic embodiment realizes the integrated design and integral assembly of the components of the foaming mold 4 by mounting the main body mold core 42, the box bottom mold core 43, the box top mold core 44 and the plurality of side plate upper positioning mechanisms 45 on the main body fixing frame 41, thus, compared with the prior art vertical display refrigerator box body foaming mold which adopts the mode of separately pre-inserting the block mold into the box body to be foamed, the embodiment simplifies the assembly process flow of the foaming mold 4 during production, and can better ensure the size matching precision between the components of the foaming mold 4; on this basis, the side plate upper positioning mechanism 45 on the foaming mold 4 is inserted with the positioning pin group on the top surface of the left and right side plates of the foaming clamp to realize the matching positioning of the foaming mold 4 and the foaming clamp, thus, compared with the prior art mode of pressing the foaming clamp on the foaming mold by the external locking mechanism, the embodiment reduces the setting of the external locking mechanism 6a, and can better ensure the size matching precision between the foaming mold 4 and the foaming clamp; in addition, during the box body remodeling production, the embodiment directly replaces the entire foaming mold 4, and then realizes the direct matching positioning of the foaming mold 4 and the foaming clamp through the side plate upper positioning mechanism 45, thus, compared with the prior art, the embodiment omits the operation of adjusting and positioning the foaming clamp and the block mold after the box body remodeling, can make the mold loading and unloading of the foaming mold 4 more convenient and reliable, reduces the difficulty of mold replacement, and significantly improves the mold replacement efficiency; moreover, through the application of the integral foaming mold 4 and the side plate upper positioning mechanism 45, the embodiment makes the matching precision between the components of the foaming mold 4 and between the foaming mold 4 and the foaming clamp more accurate and reliable, thus making the foaming equipment more accurately hold the box body to be foamed, can significantly improve the one-time remodeling qualification rate of the box body, reduce the situation of scrapping the trial mold foaming box body due to quality problems, and is especially suitable for multi-model small-batch box body production.

[0043] As Figure 3 , Figure 7 , Figure 9As shown, in some embodiments, the foaming fixture further comprises a bottom plate 33 between the left side plate 31 and the right side plate 32, a front baffle 34 and a rear baffle 36 arranged oppositely. The front end of the front baffle 34 is hinged with a front hanging plate 35 fixedly hung under the top frame 21 of the main frame 2; the rear end of the rear baffle 36 is hinged with a rear hanging plate 37 hung under the top frame 21 of the main frame 2 and movable along the front-rear direction of the top frame 21. A plurality of pairs of baffle positioning holes 331 are arranged on the bottom plate 33 along the front-rear direction, and a pair of hanging plate positioning pins 371 are arranged on the bottom surface of the rear hanging plate 37 corresponding to each pair of baffle positioning holes 331. Those skilled in the art can understand that when the box is changed, the size of the box top mold core 44 is designed according to the size of the changed box, so that the rear hanging plate 37 can be positioned by inserting the hanging plate positioning pin 371 into the baffle positioning hole 331 on the bottom plate 33 after moving. In this illustrative embodiment, the matching arrangement of the baffle positioning hole 331 and the hanging plate positioning pin 371 realizes multi-stage distance adjustment of the position of the rear baffle 36, further reduces the difficulty of mold changing and improves the efficiency of mold changing.

The main core plate 421 is installed on the bottom surface of the main body fixing frame 41, and the expansion plate 422 is hinged to the outside of the main core plate 421. When foaming, the main mold core 42 is attached to the inner cavity of the main body area 12 of the box 1, and the action of the expansion plate 422 meets the foaming needs of the undercut surface in the inner cavity of the main body area 12 and the demolding needs after foaming.

[0045] As shown in Figure 1 , Figure 6 In some embodiments, the box bottom mold core 43 comprises a bottom core fixing plate 431 and a bottom core clamping plate 432. The bottom core fixing plate 431 is installed on the bottom surface of the main body fixing frame 41, and the bottom core clamping plate 432 is hinged to the side of the bottom core fixing plate 431 close to the main mold core 42. When the foaming equipment is foaming, the bottom core clamping plate 432 is attached to the inner cavity of the press area 11 of the box 1; when the foaming equipment is opened after foaming is completed, the bottom core clamping plate 432 acts downward to separate from the box 1, meeting the demolding needs of the box.

[0046] As shown in Figure 1 , Figure 6As shown in the drawings, in some embodiments, the box top mold core 44 comprises a top core fixing plate 441 and a top core clamping plate 442. The top core fixing plate 441 is installed on the bottom surface of the main body fixing frame 41, and the top core clamping plate 442 is hinged to one side of the top core fixing plate 441 close to the main body mold core 42. When the foaming device is closed for foaming, the top core clamping plate 442 is attached to the inner cavity of the lamp box area 13 of the box body 1, and if the box body 1 does not have a lamp box area 13, the top core clamping plate 442 is attached to the top surface of the box body 1. When the foaming device is opened after foaming is completed, the top core clamping plate 442 is actuated downward to disengage from the box body 1, meeting the needs of box demolding.

[0047] As shown in the drawings, Figure 3 , Figure 5 , Figure 7 As shown in the drawings, in some embodiments, a plurality of mold positioning pins 22 are arranged on the top frame 21 of the main frame 2 in the front-rear direction, and the top surface of the main body fixing frame 41 of the foaming mold 4 is provided with a plurality of mold positioning holes 411 matched with the mold positioning pins 22, so as to realize the assembly and positioning of the foaming mold 4 on the main frame 2.

[0048] As shown in the drawings, Figure 3 , Figure 5 , Figure 7 , Figure 8 As shown in the drawings, in some embodiments, the top frame 21 of the main frame 2 is provided with a mold locking device 23 to lock the foaming mold 4 on the top frame 21. Further, the mold locking device 23 specifically comprises a push plate 231, an air cylinder 232, two connecting strips 233 and a plurality of pairs of locking wheels 234. The two connecting strips 233 are arranged on the left and right sides of the top frame 21, and each connecting strip 233 extends in the front-rear direction. The plurality of pairs of locking wheels 234 are arranged on the top frame 21 in the front-rear direction and are all rotationally connected with the top frame 21 through rotating shafts, and each rotating shaft is connected with an adjacent connecting strip 233 through a pull plate. The push plate 231 extends in the left-right direction, and its two ends are connected with the two connecting strips 233, respectively. The output end of the air cylinder 232 is connected with the push plate 231. The movement of the push plate 231 is driven by the actuation of the air cylinder 232 to drive the movement of the two connecting strips 233, and the rotating shafts and the locking wheels 234 are deflected through the pull plates to lock the main body fixing frame 41 of the foaming mold 4, thereby realizing the locking of the foaming mold 4 on the top frame 21.

[0049] In summary, the vertical display freezer box foaming equipment of the present application can quickly change the type, through the application of the integrated foaming mold 4 and the positioning mechanism 45 on the side plate, solves the problems of high difficulty and low efficiency in changing the mold during the production of the existing vertical display freezer box, makes the mold assembly and disassembly of the foaming mold more convenient and reliable, reduces the difficulty of changing the mold, improves the efficiency of changing the mold, and makes the matching precision between the components of the foaming mold and between the foaming mold and the foaming clamp higher and more reliable, thereby significantly improving the one-time change qualification rate of the box body.
