An air fryer shell demolding structure

Abstract

This utility model discloses a demolding structure for an air fryer shell, belonging to the field of product demolding technology. The mold includes a mounting base plate, a lower mold, a sliding rod, a mounting top plate, a pressing cylinder, an upper mold, a filling pipe, a lifting plate, a plug-in column, and a telescopic component. After the product cools and solidifies, the pressing cylinder contracts, causing the upper mold to move upward, and the formed shell separates from the inner wall of the upper mold. At this time, the outermost lifting plates rise first, thereby increasing the contact area between the lifting plates and the formed shell during demolding, so that the formed shell will not deform or crack when lifted. When the outer lifting plates rise, the formed shell separates from the outer wall of the lower mold and the multiple lifting plates at the center, and also becomes adhered to the outer lifting plates. At this time, the outer lifting plates descend, causing the central lifting plate to rise, thereby separating the formed shell from the multiple outer lifting plates, resulting in a better demolding effect.

Description

Technical Field

[0001] This utility model belongs to the field of product demolding technology, specifically, it relates to a demolding structure for the outer shell of an air fryer. Background Technology

[0002] An air fryer is a machine that uses air to "fry" food. It mainly uses air to replace the hot oil in a frying pan to cook the food. At the same time, the hot air blows away the moisture on the surface of the food, giving the ingredients an effect similar to deep-frying.

[0003] The outer shell of an air fryer needs to be produced using injection molding tools. For example, Chinese utility model patent CN218615145U discloses a demolding structure for an air fryer outer shell. The ejection mechanism is designed to facilitate the ejection of the workpiece. The motor drives the cam to rotate, which in turn drives the ejection frame to swing up and down, making it easier for the workpiece to detach from the bottom mold. The protective cover is designed to better protect the motor. The spring is designed to facilitate the motor to drive the ejection frame to swing up and down. The first and second limit beads are designed to better reduce the friction between the first and second sliding plates and the mounting groove.

[0004] Although this mold allows for better demolding, the ejector is located in the center of the molded shell. When the ejector rises, the molded shell still adheres to the lower mold. The small ejection area makes the molded shell prone to cracking, resulting in defective products. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that although the mold can achieve better demolding, the ejector is located at the center of the molded shell, and the molded shell still adheres to the lower mold when the ejector rises, the small ejection area makes the molded shell prone to cracking and producing defective products, the present invention adopts the following technical solution.

[0007] An air fryer shell demolding structure includes a mounting base plate, a lower mold detachably connected to the upper end of the mounting base plate, sliding rods detachably connected to both sides of the upper end of the mounting base plate, a mounting top plate detachably connected to the top of the sliding rods, a pressing cylinder detachably connected to the upper end of the mounting top plate, the telescopic end of the pressing cylinder passing through the mounting top plate and detachably connected to the upper mold, an injection tube provided on the upper mold, multiple rectangular arrayed inner grooves provided on the upper end of the mounting base plate, a connecting hole provided on the bottom inner side of each inner groove, a mounting cavity provided on the bottom of the mounting base plate, the connecting hole communicating with the mounting cavity, a lifting plate installed inside each inner groove, a plug-in post fixedly connected to the bottom of each lifting plate, each plug-in post inserted into the interior of the connecting hole, a telescopic component installed inside the mounting cavity, the telescopic component enabling the multiple outer lifting plates and the multiple central lifting plates to rise and fall independently.

[0008] Preferably, the bottom of the outermost plurality of plug-in posts is detachably connected to a U-shaped connecting plate, and the bottom of the central plurality of plug-in posts is detachably connected to a rectangular connecting plate.

[0009] Preferably, a first electric telescopic rod is detachably connected to the upper center of the mounting base plate, and the telescopic end of the first electric telescopic rod is detachably connected to the bottom of the rectangular connecting plate. A second electric telescopic rod is detachably connected to one side of the upper end of the mounting base plate, and the telescopic end of the second electric telescopic rod is detachably connected to the bottom of the U-shaped connecting plate. Both the first electric telescopic rod and the second electric telescopic rod are located in the mounting cavity of the lower mold.

[0010] Preferably, a cross-shaped connecting frame is fixedly connected to the bottom of the U-shaped connecting plate, and each vertical side of the cross-shaped connecting frame is detachably connected to the bottom of each horizontal side of the U-shaped connecting plate. The telescopic end of the first electric telescopic rod passes through the cross-shaped connecting frame, and the telescopic end of the second electric telescopic rod is detachably connected to the bottom of the cross-shaped connecting frame.

[0011] Preferably, the two outer walls of the upper mold are detachably connected with sliding lugs, which are slidably connected to the outer wall of the sliding rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. After the product cools and solidifies, the downward pressure cylinder contracts, causing the upper mold to move upward. The outer shell of the molded product separates from the inner wall of the upper mold. At this time, the outermost lifting plates rise first, which increases the contact area between the lifting plates and the outer shell of the molded product during demolding. This prevents the outer shell of the molded product from deforming and cracking during the lifting process. When the outer lifting plates rise, the outer shell of the molded product separates from the outer wall of the lower mold and the multiple lifting plates at the center. It also becomes adhered to the outer lifting plates. At this time, the outer lifting plates descend, causing the lifting plate at the center to rise. This allows the outer shell of the molded product to separate from the multiple outer lifting plates, resulting in a better demolding effect and preventing the outer shell of the molded product from cracking.

[0014] 2. The first electric telescopic rod extends to enable the rectangular connecting plate to raise and lower multiple lifting plates in the middle, and the second electric telescopic rod enables the U-shaped connecting plate to raise and lower multiple lifting plates on the periphery.

[0015] 3. By setting the cross-shaped connecting frame, the force on the connecting plate can be more even when the second electric telescopic rod extends and raises multiple external lifting plates, thereby avoiding damage to the molded shell during demolding due to uneven force.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] like Figure 1 The diagram shown is a preferred embodiment of the air fryer shell demolding structure of this utility model. The air fryer shell demolding structure of this embodiment includes a mounting base plate 100. A lower mold 200 is detachably connected to the upper end of the mounting base plate 100. Sliding rods 101 are detachably connected to both sides of the upper end of the mounting base plate 100. A mounting top plate 102 is detachably connected to the top of the sliding rods 101. A pressing cylinder 103 is detachably connected to the upper end of the mounting top plate 102. The telescopic end of the pressing cylinder 103 passes through the mounting top plate 102. The upper mold 104 is detachably connected to the upper mold 104. Sliding lugs 105 are detachably connected to the outer walls of both sides of the upper mold 104. The sliding lugs 105 are slidably connected to the outer wall of the sliding rod 101. An injection tube is provided on the upper mold 104. In this embodiment, the upper mold 104 slides downward on the outer wall of the sliding rod 101 through the sliding lugs 105 on both sides by extending the lower mold 200 until the upper mold 104 and the lower mold 200 are in contact. The raw material is injected between the upper mold 104 and the lower mold 200 through the injection tube. The raw material is formed after cooling.

[0027] like Figure 2As shown, this is a schematic diagram of the lifting plate structure in this embodiment. The upper end of the mounting base plate 100 is provided with multiple rectangular arrayed recesses 201. Each recess 201 has a connecting hole 202 at its inner bottom. The bottom of the mounting base plate 100 has a mounting cavity, and the connecting hole 202 communicates with the mounting cavity. A lifting plate 203 is installed inside each recess 201. A plug-in post 204 is fixedly connected to the bottom of each lifting plate 203. Each plug-in post 204 is inserted into the connecting hole 202. The bottoms of the outermost plug-in posts 204 are detachably connected to a U-shaped connecting plate 205, and the bottoms of the central plug-in posts 204 are detachably connected to a rectangular connecting plate 206. In this embodiment, after the product cools and solidifies, downward pressure is applied... When cylinder 103 contracts, the upper mold 104 moves upward, and the molded outer shell separates from the inner wall of the upper mold 104. At this time, the outermost lifting plates 203 first rise, thereby increasing the contact area between the lifting plates 203 and the molded outer shell during demolding. This prevents the molded outer shell from deforming and cracking during lifting. When the outer lifting plates 203 rise, the molded outer shell separates from the outer wall of the lower mold 200 and the multiple lifting plates 203 at the center, and also becomes adhered to the outer lifting plates 203. At this time, the outer lifting plates 203 descend, causing the central lifting plate 203 to rise, thereby separating the molded outer shell from the multiple outer lifting plates 203, resulting in a better demolding effect and preventing the molded outer shell from cracking.

[0028] like Figure 3 As shown, this is a schematic diagram of the lifting assembly structure in this embodiment. A first electric telescopic rod 207 is detachably connected to the upper center of the mounting base plate 100. The telescopic end of the first electric telescopic rod 207 is detachably connected to the bottom of the rectangular connecting plate 206. A second electric telescopic rod 208 is detachably connected to one side of the upper end of the mounting base plate 100. The telescopic end of the second electric telescopic rod 208 is detachably connected to the bottom of the U-shaped connecting plate 205. Both the first electric telescopic rod 207 and the second electric telescopic rod 208 are located in the mounting cavity of the lower mold 200. In this embodiment, the extension of the first electric telescopic rod 207 enables the rectangular connecting plate 206 to drive the multiple lifting plates 203 in the middle to rise and fall. The extension of the second electric telescopic rod 208 enables the U-shaped connecting plate 205 to drive the multiple lifting plates 203 on the periphery to rise and fall.

[0029] like Figure 4As shown, this is a schematic diagram of the cross-shaped connecting frame structure in this embodiment. The bottom of the U-shaped connecting plate 205 is fixedly connected to the cross-shaped connecting frame 209. Each vertical side of the cross-shaped connecting frame 209 is detachably connected to the bottom of each horizontal side of the U-shaped connecting plate 205. The telescopic end of the first electric telescopic rod 207 passes through the cross-shaped connecting frame 209, and the telescopic end of the second electric telescopic rod 208 is detachably connected to the bottom of the cross-shaped connecting frame 209. In this embodiment, by setting the cross-shaped connecting frame 209, the force on the U-shaped connecting plate 205 can be more uniform when the second electric telescopic rod 208 extends to raise the multiple external lifting plates 203, thereby avoiding damage to the molded shell during demolding due to uneven force.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions.
