Embodiment Construction

[0022] see figure 1 , figure 2 , image 3 and Figure 4 , the characteristics of the ejection mechanism of the single-station foaming machine of the refrigerator in this embodiment are:

[0023] The front connecting frame rod 4, the rear connecting frame rod 7, the left camshaft 8, and the right camshaft 3 are hinged to form a parallel four-bar mechanism distributed in a rectangular frame on the plane. The parallel four-bar mechanism makes each ejector rod move well. consistency.

[0024] On the left camshaft 8 and the right camshaft 3, cams are respectively arranged one after the other. Taking the cam 9 arranged on the front side on the left camshaft 8 as an example, the cam 9 and the connecting rod 2 connected with the cam 9 , the ejector rod 1 that is connected with the connecting rod 2, and the foaming special machine bottom plate that is fixedly arranged on the ejector rod 1 constitutes a slider crank mechanism; in addition, the cam that is arranged on the rear side ...

Abstract

The invention discloses an ejector mechanism of a single-trip foaming special machine of a refrigerator and a control method of the ejector mechanism. The ejector mechanism is characterized in that a parallel four-bar mechanism is formed by articulating a front connecting rod frame, a rear connecting rod frame, a left camshaft and a right camshaft which are distributed as a rectangular frame on a plane, wherein cams are respectively arranged on the left camshaft and the right camshaft front and back, a slider-crank mechanism consists of the cams, connecting rods connected with the cams, ejector rods connected with the connecting rods, and foaming special machine bottom plates fixedly arranged on the ejector rods, a pre-positioned air cylinder and a post-positioned air cylinder are arranged as a driving mechanism, the left camshaft is driven to rotate by a piston rod of the pre-positioned air cylinder through a pre-positioned crank, and the right camshaft is driven to rotate by a piston rod of the post-positioned air cylinder through a post-positioned crank. According to the ejector mechanism, the foaming can be realized on the single foaming special machine.

Description

technical field [0001] The invention relates to refrigerator foaming equipment, more specifically to a single-station foaming machine ejection mechanism for a refrigerator and a control method thereof. Background technique [0002] As a daily household appliance, a refrigerator is mainly composed of various sheet metal parts, plastic liners, positioning plates, internal accessories, compressors, refrigeration pipes, and insulation materials. The foaming of refrigerator cabinets is an important part of refrigerator production. The efficiency of production and the quality of refrigerator products depend on the performance of foaming equipment and foaming molds. During the foaming and forming process of the refrigerator, each component in the box is pre-assembled in the pre-assembly team. After completion, it enters the foaming production line through the preheating oven. After reaching the position, the foaming mold is closed and the trolley is locked. When the outer panel of...
