Description

Technical Field

[0001] The invention belongs to the technical field of demoulding mechanisms, and in particular relates to a lateral demoulding mechanism for a refrigerator foaming mold. Background Art

[0002] At present, the internal structure of refrigerators is becoming more and more complicated. Some small and medium-sized direct cooling refrigerators usually install the lighting integrated components (commonly known as light boxes) on one side of the box lining. The area that accommodates the light box components is called the light box slot. The production line usually installs the light box after the box is foamed. During the foaming process, the refrigerator box (refrigerated and frozen compartments) is supported by the box foaming mold. If the light box slot lacks effective support inside during the foaming process, it will be deformed due to the pressure of the foaming liquid, resulting in the inability of the light box to be inserted later. Due to the large volume and depth of the light box slot, the corresponding support lining mold will be difficult to be directly installed on the outer wall of the foaming mold because the mold cannot provide enough clearance space. The traditional method is usually to manually attach the lining mold to the light box slot during the pre-installation process before foaming.

[0003] The traditional method of dealing with partial foaming of the lamp box has many disadvantages: 1. The manual attachment of the lamp box slot lining mold increases labor costs and material costs; 2. Manual attachment of the lining mold takes up the production hours of the refrigerator and reduces efficiency; 3. In actual production, manual attachment is prone to errors such as the lining mold not matching the lamp box slot, resulting in damage to the foaming of the lamp box slot; in addition, due to the limitations of the box release fixture itself, many old-style box release lines do not have pneumatic functions, and the existing mechanical lifting rod structure of the box release mold in the industry is difficult to achieve. Summary of the invention

[0004] The purpose of the present invention is to provide a lateral demoulding mechanism for the side of a refrigerator foaming mold, which solves the problems of high cost, low efficiency and poor precision of the existing manually attached lamp box slot lining mold through the functions of a mechanism mounting frame, a short connecting rod, a lining mold and a lining mold mounting seat.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a lateral demolding mechanism for the side of a refrigerator foaming mold, comprising a mechanism mounting frame fixed on a side plate of a box foaming mold; a lining mold is detachably mounted on the rear side of the mechanism mounting frame; a lining mold mounting seat is installed in the lining mold, and a short connecting rod is rotatably arranged on the lining mold mounting seat; the short connecting rod is rotatably connected to a long connecting rod and a fixed connecting plate fixed to a mold fixing plate in turn; a through groove is provided in the middle of the front side of the mechanism mounting frame, and a pair of inclined guide rail grooves are symmetrically provided on both sides of the mechanism mounting frame; the long connecting rod is movably fitted in the inclined guide rail groove.

[0007] Furthermore, a pair of positioning holes are symmetrically provided at the upper and lower ends of the front side of the mechanism mounting frame; and a mounting hole for fixing to the side plate of the box-launching mold is provided on the mechanism mounting frame.

[0008] Furthermore, the front side of the lining mold is provided with an assembly hole corresponding to a pair of positioning holes; a guide column is installed between the positioning hole and the assembly hole, and is matched with a guide sleeve; one end of the guide column is provided with a connecting hole corresponding to the assembly hole, and is matched with a connecting piece.

[0009] Furthermore, a mounting groove cooperating with the lining mold mounting seat is provided on the front side of the lining mold; and a through hole A corresponding to the lining mold mounting seat is provided on the inner bottom surface of the mounting groove.

[0010] Furthermore, a connecting base is provided on the liner mold mounting seat; and a through hole B corresponding to the through hole A is opened on the liner mold mounting seat.

[0011] Furthermore, the short connecting rod is a connecting rod structure with holes at both ends; the holes at both ends of the short connecting rod are respectively equipped with a rotating shaft A assembled with the liner mold mounting seat and the long connecting rod; the circumferential side of the rotating shaft A is equipped with a shaft sleeve.

[0012] Furthermore, the long connecting rod is a connecting rod structure with holes at both ends; a through hole C for installation is opened on the fixed connecting plate; a mounting platform is provided on the fixed connecting plate; a rotating shaft B assembled with the long connecting rod is passed through the mounting platform.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention is fixed to the side plate of the box hair-making mold by a mechanism mounting frame, and a lining mold is detachably installed on the rear side of the mechanism mounting frame. By directly installing the lining mold for the lamp box on the side plate of the hair-making mold, the lining mold is connected to the demoulding mechanism shown in the device, and the lining mold can be automatically ejected and retracted with the up and down movement of the side plate, thereby realizing automatic attachment of the lamp box core-pulling lining mold, improving production efficiency and reducing production costs.

[0015] 2. The present invention is connected to a long connecting rod and a fixed connecting plate fixed to a mold fixing plate by a short connecting rod, and the gravity is converted into a lateral demoulding force through the short connecting rod. The lining mold of the lamp lining is driven to move into the mold through natural sagging by the short connecting rod; the long connecting rod is movably fitted in the inclined guide rail groove, and the movement trajectory is limited by the inclined guide rail groove.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figure 6 As shown, the front side of the liner 4 is provided with assembly holes 403 corresponding to the pair of positioning holes 103; a guide column 7 is installed between the positioning hole 103 and the assembly hole 403, and is matched with a guide sleeve 701; one end of the guide column 7 is provided with a connecting hole 702 corresponding to the assembly hole 403, and is matched with a connecting piece.

[0037] Working principle: before foaming, the clamp is opened, and the pre-installed box enters the clamp. At this time, the side plate of the box foaming mold falls due to gravity, driving the mechanism mounting frame 1 fixed on the side plate to move synchronously in the Y-axis direction. The long connecting rod 6 and the fixed connecting plate 9 are fixed on the mold fixing plate 5 and remain relatively static during the entire movement process; the mechanism mounting frame 1 is processed with an inclined guide groove 101, which drives the rotating shaft A3 and the sleeve 301, the short connecting rod 2, and the liner mold mounting seat 8 to move in the X-axis direction during the movement, pulling the liner mold 4 inward and retracting. This state allows the foaming mold to avoid all the gaps in the pre-installed box. During foaming, the clamp closes and rises, and the box foaming mold rises and expands under the action of the side wall of the clamp. The liner mold 4 is ejected according to the above principle and fits the light box groove in the pre-installed box.
