Forming die for an energy-saving anti-kink edge refrigerator door seal

Abstract

This utility model provides a molding die for an energy-saving, anti-tangle refrigerator door seal, relating to the field of refrigerator door seal molding technology. It includes: a fixed base plate; grooves at both ends of the fixed base plate; and a heating mold shell fixedly installed in the middle of the fixed base plate. By using two mold frames in conjunction with a sealing plate to effectively block and restrict the material in the door seal groove, material loss is prevented. The opposing mold frames and sealing plate form a tightly closed space, completely preventing material from flowing to non-target areas and avoiding uneven filling due to material loss. The closed mold automatically presses down to compress and shape the material in the door seal groove. In this closed environment, pressure can be evenly transmitted to the entire material, solving the problem that refrigerator door seal material needs to be injected into the door seal groove for compression molding, thus requiring mold frames and sealing plates to automatically seal the material in the door seal groove, otherwise the material in the door seal groove will leak during the molding process.

Description

Technical Field

[0001] This utility model relates to the field of refrigerator door seal molding technology, and in particular to a molding die for an energy-saving anti-tangle refrigerator door seal. Background Technology

[0002] The refrigerator door seal is a crucial sealing component between the refrigerator door and the refrigerator body. Its performance directly affects the refrigerator's insulation effect and energy consumption. Traditional refrigerator door seals are prone to edge twisting during long-term use, meaning the edges of the door seal curl and deform due to repeated opening and closing or external forces, leading to poor sealing, cold air leakage, and increased energy consumption. Furthermore, existing door seal molding molds often use single materials or simple structural designs, making it difficult to balance flexibility and deformation resistance. The molded door seals are susceptible to fatigue damage under complex stress environments. In existing technologies, the cooling system of the door seal molding mold is inefficient, resulting in long production cycles, high energy consumption, and difficulty in guaranteeing molding precision, all of which affect the sealing performance and service life of the door seal.

[0003] During the use of the molding die, since the refrigerator door seal material needs to be injected into the door seal groove and pressed into shape, the mold frame and sealing plate are needed to automatically seal the material in the door seal groove; otherwise, the material in the door seal groove will be lost during the molding process. Utility Model Content

[0004] This utility model relates to a molding die for an energy-saving, anti-tangle refrigerator door seal. It uses two mold frames and a sealing plate to effectively block and restrict the material in the door seal groove, preventing material loss. The opposing mold frames and the sealing plate form a tightly closed space, completely preventing the material from flowing to non-target areas and avoiding uneven filling caused by material loss. In this way, the closed mold automatically presses down to compress the material in the door seal groove. Under closed conditions, the pressure can be evenly transmitted to the entire material, ensuring density consistency and structural integrity. It is especially suitable for anti-tangle refrigerator door seals.

[0005] In a first aspect, this utility model provides a molding die for an energy-saving, anti-tangle refrigerator door seal, specifically comprising: a fixed base plate; grooves respectively provided at both ends of the fixed base plate; a heating mold shell fixedly installed in the middle of the fixed base plate, and heating tubes evenly installed in the middle of the heating mold shell; an upper frame installed at the upper end of the heating mold shell, and a door seal groove provided on the outer side of the upper frame of the heating mold shell. Fixed bases are fixedly installed at the grooves at both ends of the fixed base plate, and the upper end of the fixed base plate has a groove; a support frame is fixedly installed at the upper end of the fixed base plate, and a round hole is opened in the middle of the support frame, and four through guide holes are opened on the support frame. An electric cylinder is fixedly installed through the round hole in the middle of the support frame. A connecting plate is fixedly installed at the lower end of the electric cylinder. Vertically upward guide rods are fixedly installed at the four corners of the connecting plate. A ring of through bolts is inserted into the connecting plate. A closed mold is installed at the bottom of the connecting plate.

[0006] Furthermore, each of the two fixed bases has a through anti-detachment hole at both ends, and an electric push rod is fixedly installed in the groove of each of the two fixed bases.

[0007] Furthermore, mold frames are fixedly installed at opposite ends of the two electric push rods, and symmetrical anti-detachment rods are fixedly installed on the outer side of the mold frames.

[0008] Furthermore, symmetrical inserts are fixedly installed on the right side of the left mold frame, symmetrical slots are opened on the left side of the right mold frame, and c-shaped sealing plates are fixedly installed on the bottom of the two mold frames respectively.

[0009] This utility model provides a molding die for an energy-saving, anti-tangle refrigerator door seal, which has the following beneficial effects: In this invention, the forming mold uses two mold frames in conjunction with a sealing plate to effectively block and restrict the material in the door seal groove, preventing material loss. The opposing mold frames and the sealing plate form a tightly closed space, completely preventing the material from flowing to non-target areas and avoiding uneven filling caused by material loss. In this way, the closed mold automatically presses down to compress and shape the material in the door seal groove. Under closed conditions, the pressure can be evenly transmitted to the entire material, ensuring density consistency and structural integrity. It is especially suitable for refrigerator door seals that are resistant to edge twisting.

[0010] By activating the electric cylinder to push the connecting plate downwards, the sealing mold at the bottom of the connecting plate will also move downwards, smoothly placing the sealing mold onto the mold frame to seal the mold frame and the heating mold shell. The smooth downward movement of the electric cylinder seals the mold, ensuring that the sealing mold and the mold frame make even contact, avoiding local pressure leakage, and ensuring that the door seal groove material (such as PVC or TPE) is fully filled and the edges are tightly sealed. At this time, the sealing mold will press the material in the door seal groove into shape, and then the sealing mold will be moved upwards to facilitate the removal of the pressed refrigerator door seal.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example 1: Please refer to Figures 1 to 4 : This utility model proposes a molding die for an energy-saving, anti-tangle refrigerator door seal, comprising: a fixed base plate 1; grooves at both ends of the fixed base plate 1; a heating mold shell 101 fixedly installed in the middle of the fixed base plate 1, and heating tubes evenly installed in the middle of the heating mold shell 101; an upper frame installed at the upper end of the heating mold shell 101, and a door seal groove 102 provided on the outer side of the upper frame of the heating mold shell 101; the heating tubes in the heating mold shell 101 are activated to heat the mold frame, and at the same time, the material in the door seal groove 102 is heated and melted to facilitate subsequent molding; fixed bases 2 are fixedly installed in the grooves at both ends of the fixed base plate 1, and grooves are provided at the upper ends of the fixed bases 2; a support frame 3 is fixedly installed at the upper end of the fixed base plate 1, and a round hole is provided in the middle of the support frame 3.

[0016] The two fixed bases 2 each have through anti-detachment holes 201 at both ends. Electric push rods 202 are fixedly installed in the grooves of the two fixed bases 2. The two electric push rods 202 are used to push the two mold frames 203 in opposite directions, inserting the insert block 205 into the slot 206. The two mold frames 203 are then aligned with the edge of the heating mold shell 101 to form a door seal groove 102. Material is then injected into the door seal groove 102. Simultaneously, the sealing plates 207 at both ends are attached to the side walls of the heating mold shell 101. The two mold frames 203, in conjunction with the sealing plates 207, effectively block and restrict the material in the door seal groove 102. After the refrigerator door seal is formed, the two electric push rods 202 are used to pull the two mold frames 203 in opposite directions. To prevent the two mold frames 203 from obstructing the removal of the refrigerator door seal, mold frames 203 are fixedly installed at opposite ends of the two electric push rods 202. Symmetrical anti-detachment rods 204 are fixedly installed on the outer side of the mold frames 203. The anti-detachment rods 204 are slidably installed in the anti-detachment holes 201. When the mold frames 203 slide left and right, the anti-detachment rods 204 are restricted by the anti-detachment holes 201, and the mold frames 203 can only slide left and right, preventing the mold frames 203 from shifting or tilting when sliding left and right. Symmetrical inserts 205 are fixedly installed on the right side of the left mold frame 203, and symmetrical slots 206 are opened on the left side of the right mold frame 203. C-shaped sealing plates 207 are fixedly installed at the bottom of the two mold frames 203 respectively.

[0017] The support frame 3 has four through guide holes 301. A through electric cylinder 302 is fixedly installed at the central hole of the support frame 3. When the electric cylinder 302 is activated, it pushes the connecting plate 303 downward. At this time, the sealing mold 306 at the bottom of the connecting plate 303 also moves downward, placing the sealing mold 306 smoothly onto the mold frame 203, sealing the mold frame 203 and the heating mold shell 101. The heating mold shell 101 then heats the material in the door seal groove 102 to form a refrigerator door seal. Then, the sealing mold 306 is moved upward to remove the processed refrigerator door seal. The lower end of the electric cylinder 302 is fixedly installed with the connecting plate 303, and vertically upward guides are fixedly installed at the four corners of the connecting plate 303. The guide rod 304 slides through the guide hole 301. When the connecting plate 303 slides up and down, the guide rod 304 is restricted by the guide hole 301, and the connecting plate 303 can only slide up and down to prevent the connecting plate 303 from shifting or tilting when sliding up and down. The closing mold 306 will also tilt and cannot fall smoothly onto the mold frame 203. A ring of through bolts 305 is installed on the connecting plate 303. The bolts 305 on the connecting plate 303 are rotated and installed on the closing mold 306 to fix the connecting plate 303 and the closing mold 306 together. The connecting plate 303 and the closing mold 306 will not separate when they are touched. The closing mold 306 is installed at the bottom of the connecting plate 303.

[0018] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, a ring of through bolts 305 is inserted on the connecting plate 303. The bolts 305 on the connecting plate 303 are rotated and inserted into the closed mold 306, fixing the connecting plate 303 and the closed mold 306 together. The connecting plate 303 and the closed mold 306 will not separate when touched. The bolts 305 are removed, and then the bottom of the connecting plate 303 is fixedly welded to the closed mold 306, fixing the connecting plate 303 and the closed mold 306 together. The closed mold 306 will not fall off when touched, avoiding the bolts 305 from loosening and failing to secure the closed mold 306 after long-term use, and also saving on parts costs.

[0019] The working principle of this embodiment is as follows: In use, two electric push rods 202 push two mold frames 203 in opposite directions, insert the insert block 205 into the slot 206, and align the two mold frames 203 at the edge of the heating mold shell 101 to form a door seal groove 102. Then, the material is injected into the door seal groove 102. At the same time, the sealing plates 207 at both ends will also stick to the side wall of the heating mold shell 101 to seal the edge of the heating mold shell 101. The heating tube in the heating mold shell 101 is activated to heat the mold frame, and at the same time, the material in the door seal groove 102 will be heated and melted. Then, the electric cylinder 302 is activated to push the connecting plate 303 downward. At this time, the closing mold 306 at the bottom of the connecting plate 303 will also move downward, and the closing mold 306 will be placed smoothly on the mold frame 203 to seal the mold frame 203 and the heating mold shell 101. At this time, the closing mold 306 will press the material in the door seal groove 102 into shape. Then, the closing mold 306 is moved upward to remove the pressed refrigerator door seal.
