Description

Technical Field

[0001] This utility model relates to the technical field of molds, and in particular to a mold for simultaneously producing a refrigerated upper end cap and a frozen lower end cap. Background Technology

[0002] In modern refrigerator design, the refrigerator compartment and freezer compartment are usually separated into upper and lower sections. The refrigerator compartment is located at the top, and its top is usually equipped with a top cover to seal off the upper space of the refrigerator compartment, which may also support components such as lighting and air duct vents. The freezer compartment is located at the bottom, and its bottom is usually equipped with a bottom cover to seal off the lower space of the freezer compartment, which supports components such as drawer slides and evaporator coils, and also provides insulation and support.

[0003] In existing technology, the two end caps are made using separate molds, which means that two sets of targeted molds are required, leading to increased production costs. Furthermore, because the structures of the refrigerated upper end cap and the frozen lower end cap are different, the amount of glue injected is different, and the injection speed is different, it becomes difficult to manufacture them simultaneously in the same mold.

[0037] Combination Figures 1 to 4 As shown, this utility model provides a mold for simultaneously manufacturing a refrigerator top cover 310 and a freezer bottom cover 320, comprising: a front mold having an injection port; and a rear mold 10 having a first molding cavity 110 for manufacturing the refrigerator top cover 310 and a second molding cavity 120 for manufacturing the freezer bottom cover 320 between the rear mold and the front mold. The first molding cavity 110 and the second molding cavity 120 are respectively connected to the injection port through a branch channel 152 and a main channel 151.

[0038] Multiple flow-stop valves 130 are provided, and the multiple flow-stop valves 130 are divided into a first flow-stop valve 130 group corresponding to the first molding cavity 110 and a second flow-stop valve 130 group corresponding to the second molding cavity 120; each flow-stop valve 130 is provided with an adjusting flow channel 1311, which is located between the main flow channel 151 and the branch flow channel 152. The adjusting flow channel 1311 changes the amount of glue flowing from the main flow channel 151 to the branch flow channel 152 under the action of the position change of the flow-stop valve 130;

[0039] Two sets of slider groups 140 are respectively movably disposed on both sides of the rear mold 10. Each set of slider groups 140 is provided with a first inclined ejector 141 and a second inclined ejector 142. When the mold is closed, the first inclined ejector 141 is connected to the first molding cavity 110, and the second inclined ejector 142 is connected to the second molding cavity 120. When the mold is opened, the first inclined ejector 141 is separated from the first molding cavity 110, and the second inclined ejector 142 is separated from the second molding cavity 120.

[0040] Specifically, this application defines the shut-off valve 130 as a first shut-off valve group 130 and a second shut-off valve group 130, depending on the different molding cavities. The first shut-off valve group 130 corresponds to the first molding cavity 110 and contains three shut-off valves 130, which are respectively positioned at the front, middle, and rear of the first molding cavity 110. Similarly, the second shut-off valve group 130 corresponds to the second molding cavity 120 and also contains three shut-off valves. 130, three flow control valves 130 are respectively set at the front, middle and rear positions of the second molding cavity 120; when the mold is closed, the first inclined ejector 141 is connected to the first molding cavity 110, and the second inclined ejector 142 is connected to the second molding cavity 120; molten plastic enters the main flow channel 151 from the injection port, and the main flow channel 151 enters the branch flow channel 152 through the regulating flow channel 1311 in the flow control valve 130, and finally is injected into the first molding cavity 110 and the second molding cavity 120.

[0041] Because the products (i.e., the refrigerated top cover 310 and the frozen bottom cover 320) have large differences in shape and size, the positions of the three throttling valves 130 in the first throttling valve group and the three throttling valves 130 in the second throttling valve group are adjusted accordingly based on the different products in the first molding cavity 110 and the second molding cavity 120. This changes the amount of glue injected into the branch channel 152 from the main channel 151 where the throttling valves 130 are located, making the glue injection in the two molding cavities uniform. This allows for the simultaneous production of both the refrigerated top cover 310 and the frozen bottom cover 320 in the same mold, improving production efficiency.

[0042] During mold opening, the two sets of sliders 140 are located on the left and right sides of the rear mold 10, respectively. The two sets of sliders 140 move outward, thereby separating the first inclined ejector 141 from the first molding cavity 110 and the second inclined ejector 142 from the second molding cavity 120, and demolding the refrigerated upper end cover 310 and the frozen lower end cover 320.

[0043] Compared with the prior art, this application innovatively designs two molding cavities in the same mold, and adjusts the injection amount at the corresponding position by changing the position of the cut-off valve 130 to make the injection of the two molding cavities uniform; moreover, the first inclined ejector 141 and the second inclined ejector 142 of the two slider groups 140 can be separated from the two molding cavities when the mold is opened, which facilitates product demolding.

[0044] In this embodiment, the number of shut-off valves 130 in the first shut-off valve group 130 is the same as the number of shut-off valves 130 in the second shut-off valve group 130. The first shut-off valve group 130 is distributed sequentially along the length direction of the first molding cavity 110, and is respectively distributed at the front, middle and rear positions of the first molding cavity 110. The second shut-off valve group 130 is distributed sequentially along the length direction of the second molding cavity 120, and is respectively distributed at the front, middle and rear positions of the second molding cavity 120.

[0045] Furthermore, the first molding cavity 110 and the second molding cavity 120 are arranged in parallel.

[0046] In this embodiment, the first throttling valve group 130 and the second throttling valve group 130 are both located between the first molding cavity 110 and the second molding cavity 120, so that the first throttling valve group 130 and the second throttling valve group 130 can share the main flow channel 151.

[0047] In this embodiment, the rear mold 10 is provided with a plurality of receiving grooves 160; the flow-stopping valve 130 is slidably disposed in the receiving groove 160 so as to slide in the receiving groove 160 and change the position of the flow-stopping valve 130, thereby adjusting the amount of glue injected from the main channel 151 into the branch channel 152.

[0048] Furthermore, the shut-off valve 130 includes a sliding seat 131 and a locking member 1312. The sliding seat 131 is provided with an elongated hole 1313. After determining the position of the sliding seat 131 relative to the receiving groove 160, the locking member 1312 passes through the elongated hole 1313 and is fixedly connected to the fixing hole of the receiving groove 160 to fix the sliding seat 131 on the mold.

[0049] Furthermore, the sliding seat 131 is also provided with the regulating flow channel 1311 and the baffle 1314, the baffle 1314 being arranged adjacent to the regulating flow channel 1311. The sliding seat 131 has three states relative to the receiving groove 160; the first is the fully open state, where the main flow channel 151, the regulating flow channel 1311, and the branch flow channel 152 are on the same straight line, and the amount of glue flowing from the main flow channel 151 into the branch flow channel 152 is 100%; the second is the fully closed state, where the main flow channel 151, the regulating flow channel 1311, and the branch flow channel 152 are not on the same straight line, and the main flow channel 151 and the branch flow channel... The flow is blocked by the flow-blocking part 1314 between 152, and the amount of glue flowing from the main flow channel 151 into the branch flow channel 152 is 0% at this time; the third is a partial flow state, where the flow-blocking part 1314 partially blocks the main flow channel 151, and the main flow channel 151 can flow to the branch flow channel 152 through the adjustment channel 1311. At this time, the amount of glue flowing from the main flow channel 151 into the branch flow channel 152 is 0% to 100%.

[0050] In this embodiment, the slider assembly 140 is provided with a longitudinal inclined groove; the front mold is provided with an inclined guide rod 143, which is inserted into the longitudinal inclined groove; when the mold is opened, the front mold drives the inclined guide rod 143 to move upward, and the slider assembly 140 moves laterally outward under the driving action of the inclined guide rod 143, so that the first inclined top 141 separates from the first molding cavity 110 and the second inclined top 142 separates from the second molding cavity 120, so as to facilitate the demolding of the refrigerated upper end cover 310 and the frozen lower end cover 320.

[0051] Furthermore, the slider assembly 140 is provided with a first transverse inclined groove and a second transverse inclined groove, the first transverse inclined groove and the second transverse inclined groove are distributed in a figure-eight shape; the first transverse inclined groove is provided with a first inclined top 141, and the second transverse inclined groove is provided with a second inclined top 142, thereby facilitating the opening of the first inclined top 141 and the second inclined top 142, and facilitating the disengagement of the refrigerator upper end cover 310 and the freezer lower end cover 320.

[0052] Furthermore, the first inclined top 141 is provided with a first contouring part at one end facing the first molding cavity 110; the second inclined top 142 is provided with a second contouring part at one end facing the second molding cavity 120.

[0053] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model.
