Description

Technical Field

[0001] The invention relates to the technical field of shaping material forming, in particular to a quantitative automatic opening door foaming production line. Background Art

[0002] The foam layer of the refrigerator door plays a vital role in the refrigerator. First of all, the foam layer can prevent heat exchange between the inside of the refrigerator and the external environment, thereby keeping the temperature inside the refrigerator constant. Specifically, the foam layer is wrapped between the outer shell and the inner tank of the box, effectively preventing the leakage of cold air in the box and maintaining a constant low temperature inside the box. In addition, the foam layer can also play a heat-insulating role and reduce the effect of heat and cold transfer. The foam layer can reduce the impact of external temperature on the inside of the refrigerator, ensuring the freshness and storage time of food.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-7 The embodiment of the present invention provides a quantitative automatic opening door body foaming production line, comprising a support frame 1, an electric slide rail 2 provided on the support frame 1, a plurality of lower molds 3 being slidably connected to the electric slide rail 2, each of the plurality of lower molds 3 being provided with a driving component 4 at one end, and each of the plurality of driving components 4 being provided with an upper mold 5 at the other end, and the driving component 4 being capable of driving an upper mold 5 and a lower mold 3 to fit together;

[0032] An operating table 6 is provided next to the support frame 1;

[0033] A blanking assembly 7 is provided on the electric slide rail 2. When the blanking assembly 7 contacts a lower mold 3, the blanking assembly 7 can flow the raw material into the lower mold 3.

[0034] When the lower material assembly 7 is not in contact with the lower mold 3 , the output end of the discharge pipe 77 in the lower material assembly 7 is changed from the downward direction to the upward direction.

[0035] Preferably, each of the lower molds 3 is provided with an abutment rod 31. The length of the abutment rod 31 is adjusted so that the discharge assembly only discharges the raw material when the lower mold 3 is located below the discharge tube 77. This prevents the raw material from being discharged after the lower mold 3 has left the discharge tube 77, preventing it from dripping onto the electric slide 2 and thus preventing the raw material from affecting the movement of the electric slide 2. Furthermore, this prevents any disruption to equipment maintenance by personnel.

[0036] Preferably, the driving assembly 4 includes a plurality of cross bars 41 respectively corresponding to the plurality of lower molds 3, three limit members 42 are respectively provided on the plurality of cross bars 41, an electric telescopic rod 43 is respectively provided at the bottom of the plurality of limit members 42, and the plurality of electric telescopic rods 43 respectively pass through the plurality of limit members 42 in a one-to-one manner, and an arc block 44 is respectively provided at the output end of the plurality of electric telescopic rods 43, and one end of each arc block 44 is rotatably connected to a connecting member 45. The arc block 44 is driven to move up or down by the electric telescopic rod 43, so that the connecting member 45 can move up and down, driving the upper mold 5 to move up and down.

[0037] Preferably, the driving assembly 4 also includes a plurality of motors 46 that are slidably connected to the plurality of limit members 42 in a one-to-one manner, and each of the limit members 42 is provided with a through slot. The output ends of the plurality of motors 46 pass through the plurality of through slots to the interior of the plurality of limit members 42 in a one-to-one manner, and the output ends of the plurality of motors 46 are fixedly connected to one end of the plurality of connecting members 45 close to the arc block 44 in a one-to-one manner. The motor 46 drives the connecting member 45 to rotate, so that the upper mold 5 can rotate. At the same time, the upper mold 5 is lifted and lowered by the electric telescopic rod 43, so that the upper mold 5 can be fitted and separated with the lower mold 3, which is convenient for adding raw materials and removing the workpiece after forming.

[0038] Preferably, the other ends of the plurality of connectors 45 are fixedly connected to the plurality of upper molds 5 respectively.

[0039] Preferably, the blanking component 7 includes a fixed seat 71 fixedly set on the electric slide rail 2, and two first spring telescopic members 72 are provided in the fixed seat 71. An inclined block 73 is provided at the output end of the two first spring telescopic members 72, and the inclined block 73 passes through the outside of the fixed seat 71. The inclined block 73 corresponds to the position of the abutment rod 31, and the abutment rod 31 contacts the inclined surface of the inclined block 73, so that the inclined block 73 moves toward the inside of the fixed seat 71, causing the two first spring telescopic members 72 to contract. Through the setting of the two first spring telescopic members 72, when the abutment rod 31 no longer contacts the inclined block 73, the inclined block 73 can be driven to reset under the reset of the two first spring telescopic members 72.

[0040] Preferably, one end of the inclined block 73 located inside the fixed seat 71 is provided with one end of a first wire 74, and the other end of the first wire 74 is provided with a clamping rod 75. The clamping rod 75 is slidably connected to the inside of the fixed seat 71. The limiting assembly also includes two fixed blocks 76 arranged inside the fixed seat 71. The two fixed blocks 76 correspond to the positions of the clamping rod 75. After the inclined block 73 contacts and moves with the abutment rod 31, the first wire 74 is released for a distance, so that the clamping rod 75 is no longer pulled, and the two discharge pipes 77 are no longer clamped, so that the discharge pipe 77 can discharge at this time.

[0041] Preferably, the blanking assembly 7 also includes two discharge pipes 77 with one end passing through the fixed seat 71. The two discharge pipes 77 pass through the bottom of the fixed seat 71 and are each provided with a limit sleeve 78 on one end. The two limit sleeves 78 are rotatably connected to the two ends of a connecting rod 79 in a one-to-one manner. The tops of the two discharge pipes 77 are connected to the barrel. When the abutment rod 31 no longer contacts the inclined block 73, the two first spring telescopic members 72 are released to drive the inclined block 73 to reset so that the first wire 74 is pulled, driving the clamping rod 75 to move, so that the clamping rod 75 moves toward the two fixed blocks 76, so that the two discharge pipes 77 are clamped by the two fixed blocks 76 and a clamping block, so that the discharge pipe 77 is closed, so that the raw material no longer flows out of the discharge pipe 77, so that the discharge pipe 77 can only discharge when the lower mold 3 is located below the discharge pipe 77.

[0042] Preferably, the blanking component 7 also includes a second wire 710 having one end fixedly connected to the inclined block 73, and the other end of the second wire 710 is fixedly connected to the connecting rod 79. After the inclined block 73 contacts and moves with the abutting rod 31, the second wire 710 is released for a distance. By setting the two discharge pipes 77 to be made of rubber material, the output ends of the two discharge pipes 77 are directed toward the lower mold 3 under the gravity of the two limit sleeves 78. After the inclined block 73 no longer contacts the abutting rod 31, the inclined block 73 is reset, so that the second wire 710 is pulled for a distance, so that the connecting rod 79 is pulled, driving the two limit sleeves 78 to move, so that the output ends of the two discharge pipes 77 are pulled to the pipe mouth facing upward, preventing the residual raw material in the discharge pipe 77 from dripping onto the electric slide rail 2.

[0043] Preferably, the blanking assembly 7 also includes a torsion spring member 711 arranged on the fixed seat 71, and one end of a third wire 712 is connected to the torsion spring member 711, and the other end of the third wire 712 passes through a limit frame 713 and is connected to the connecting rod 79. The third wire 712 is limited by two limit guide wheels 714, and the two limit guide wheels 714 are arranged on the fixed seat 71 through a fixed frame 715. After the output ends of the two discharge pipes 77 are directed toward the lower mold 3, the torsion spring winds on the third wire 712, so that the connecting rod 79 is pulled, and the two limit sleeves 78 are pulled and abutted against the limit frame 713. When the discharge pipe 77 is no longer directed toward the lower mold 3, the second wire 710 pulls the movement of the connecting rod 79, so that the third wire 712 pulls the torsion spring to store force for the next movement.

[0044] Working principle: Start the electric slide rail 2 to drive the lower molds 3 to move, so that the abutting rods 31 move, so that the abutting rods 31 contact the inclined surface of the inclined block 73, so that the inclined block 73 moves toward the inside of the fixed seat 71, so that the two first spring telescopic members 72 contract, so that the first wire 74 is released for a distance, so that the clamping rod 75 is no longer pulled, so that the two discharge pipes 77 are no longer clamped, and at the same time, due to the movement of the inclined block 73, the second wire 710 is released for a distance, and by setting the two discharge pipes 77 to be made of rubber material, the output ends of the two discharge pipes 77 are in the two limit sleeves 78. When the clamping rod 75 is no longer clamped on the discharge pipe 77 , the raw material flows into the lower mold 3 through the two discharge pipes 77 . Later, due to the continuous movement of the abutting rod 31 , when the abutting rod 31 is no longer in contact with the inclined block 73 , the two first spring telescopic members 72 are released, driving the inclined block 73 to reset, causing the first wire 74 to be pulled, driving the clamping rod 75 to move , so that the clamping rod 75 moves toward the two fixed blocks 76, so that the two discharge pipes 77 are clamped by the two fixed blocks 76 and a clamping block, so that the discharge pipe 77 is closed, so that the raw material no longer flows out of the discharge pipe 77. At the same time, due to the movement of the inclined block 73, the second wire 710 is pulled a distance, so that the connecting rod 79 is pulled, driving the two limit sleeves 78 to move, so that the output ends of the two discharge pipes 77 are pulled to the pipe mouth facing upward, preventing the residual raw material in the discharge pipe 77 from dripping onto the electric slide rail 2. After that, after the lower mold 3 moves away from under the discharge pipe 77, the motor 46 is started to drive the connecting rod 79 to move. The connecting piece 45 rotates, causing the upper mold 5 to rotate to a horizontal state, and then the electric telescopic rod 43 is started to drive the upper mold 5 to move downward, so that the upper mold 5 and the lower mold 3 are fitted together, and then the raw material is foamed to fill the mold. After the raw material is foamed and formed, the electric telescopic rod 43 is started to drive the arc block 44 to move upward, so that the connecting piece 45 moves upward, driving the upper mold 5 to move upward, and then the motor 46 is started to drive the connecting piece 45 to rotate, so that the upper mold 5 rotates, so that the workpiece after foaming and forming can be taken out, and then the lower mold 3 of the workpiece after being taken out continues to move and contact the blanking component 7 again to carry out the blanking and foaming of the raw material.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
