The cooling table includes a box body and partition plates symmetrically installed on the top of the inner wall of the box body. The bottom of the partition plate is fixedly connected to the top of the through pipe. Through the design of wrapping the lower mold by the cooling cavity, the present invention greatly increases the contact area between the lower mold and the cooling water, which can not only carry away a large amount of heat in the cooling cavity, but also keep the temperature inside the cooling cavity at a relatively low temperature during the shaping process of the tableware, enabling the large-sized lunch box to be quickly cooled and shaped after injection molding, improving the injection molding and shaping rate of the tableware, and also improving the overall production efficiency of the tableware.

[0004] The existing lunch boxes are quickly cooled and formed by water cooling, which improves the processing efficiency of plastic lunch boxes. However, although the existing plastic lunch boxes can be pushed out of the mold cavity by the ejector pins arranged at the bottom after forming, the operator still needs to manually take away the ejected plastic lunch boxes to enable the mold to continue forming the next group of plastic lunch boxes, which consumes a large amount of manpower and reduces the processing efficiency of plastic lunch boxes at the same time.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figures 1-8 As shown, a molding mold for producing plastic lunch boxes includes an upper bearing plate 1. The bottom end of the upper bearing plate 1 is fixedly connected with an upper mold 2. The bottom end of the upper mold 2 is inserted into the interior of a lower mold 3. The bottom end of the lower mold 3 is fixedly connected with a connection seat 4. The bottom end of the connection seat 4 is fixedly connected with a lower bearing plate 5. An ejection and ejection mechanism is arranged inside the upper mold 2, the lower mold 3 and the connection seat 4. The ejection and ejection mechanism is used to eject the formed plastic lunch box from the interior of the lower mold 3 and eject it from the lower mold 3.

[0034] The ejection and ejection mechanism includes an ejection component and an ejection component. The ejection component is arranged at the bottom end of the lower mold 3 and inside the connection seat 4. The ejection component is used to eject the formed plastic lunch box from the lower mold 3. The ejection component is arranged between the rear side of the top end of the lower mold 3 and the bottom end of the upper mold 2. The ejection component is used to push the ejected plastic lunch box off the lower mold 3. Through the structural design of the ejection and ejection mechanism, the function of pushing the plastic lunch box to move upward synchronously during the process of the upper mold 2 lifting upward after the plastic lunch box is cooled and formed, and automatically ejecting the plastic lunch box from the lower mold 3 after the upper mold 2 is separated from the plastic lunch box is realized. There is no need for an operator to manually take the plastic lunch box, and the plastic lunch box can be automatically ejected from the lower mold 3 as the upper mold 2 rises.

[0035] Further, the ejection assembly includes a pressing plate 51 which is fixedly connected to both sides of the bottom end of the upper mold 2, and the pressing plate 51 is inserted into the interior of the receiving cavity 52 which is opened in the interior of the connecting seat 4. The bottom end of the pressing plate 51 abuts against the connecting plate 53. The connecting plate 53 is sleeved on the outer side of the guide rod 54 at positions near both sides. The guide rod 54 is fixedly connected to positions near both sides inside the receiving cavity 52. A first spring 55 is also wound around the outer side of the guide rod 54. A plurality of ejector pins 56 are fixedly connected to the top end of the connecting plate 53. The bottom end of the first spring 55 is fixedly connected to the top end of the connecting plate 53, and the top end of the first spring 55 is fixedly connected to the top end of the inner wall of the receiving cavity 52. The top ends of the ejector pins 56 are inserted into the interior of the lower mold 3, and holes matching the ejector pins 56 are opened at the bottom end of the lower mold 3.

[0036] During operation, when the plastic lunch box is to be injection-molded, the downward movement of the upper mold 2 drives the fixedly connected pressing plate 51 to move downward synchronously, so that the pressing plate 51 pushes the connecting plate 53 to drive the ejector pins 56 to move downward synchronously into the interior of the receiving cavity 52. During the downward movement of the connecting plate 53, the connecting plate 53 pulls the first spring 55 to generate elastic deformation. After the plastic lunch box is cooled and formed, the upward lifting of the upper mold 2 drives the pressing plate 51 to move upward synchronously. With the upward movement of the pressing plate 51, the connecting plate 53 and the ejector pins 56 move upward synchronously under the restoring force of the first spring 55, pushing the plastic lunch box formed inside the lower mold 3 upward, achieving the effect of automatically demolding the plastic lunch box.

[0037] Further, the ejection mechanism includes an energy storage cavity 57 which is opened at the rear side of the top end of the lower die 3. A baffle 58 is fixedly connected to a position on the inner wall of the energy storage cavity 57 close to the rear side. A plug rod 59 is fixedly connected to the front side of the baffle 58. The plug rod 59 is slidably connected to a slot 60 which is opened at the rear side of the ejection plate 61. A second spring 64 is further arranged at the rear side of the ejection plate 61. A lower hook 65 is fixedly connected to the rear side of the top end of the ejection plate 61. The lower hook 65 is engaged with an upper hook 66. The upper hook 66 is fixedly connected to the rear side of the bottom end of a rotating plate 67. A dial 68 is fixedly connected to the left side of the front end of the rotating plate 67. The right side of the rotating plate 67 is rotatably connected to the inner wall of the energy storage cavity 57. The dial 68 is also rotatably connected to the inner wall of the energy storage cavity 57. A driving assembly is arranged on the left side of the ejection plate 61. An ejection port 80 is opened at the front side of the energy storage cavity 57. A slider 62 is fixedly connected to the rear side of the bottom end of the ejection plate 61. The slider 62 is slidably connected to the inside of a chute 63 which is opened at the bottom end of the inner wall of the energy storage cavity 57. When the ejection plate 61 moves, the slider 62 fixedly connected to the ejection plate 61 slides synchronously inside the chute 63 along with the movement of the ejection plate 61. The combination of the slider 62 and the chute 63 functions to limit the moving distance of the ejection plate 61, preventing the ejection plate 61 from moving excessively and disengaging from the inside of the energy storage cavity 57 under the restoring force of the second spring 64. The front end of the second spring 64 is fixedly connected to the rear end of the ejection plate 61, and the rear end of the second spring 64 is fixedly connected to the baffle 58. A buffer block 79 is fixedly connected to the front end of the ejection plate 61. The buffer block 79 is made of sponge material. An inclined surface is opened at the rear side of the lower hook 65, and an arc surface is opened at the front side of the lower hook 65. Inclined surfaces are opened at both the front and rear sides of the upper hook 66. The inclination angle of the inclined surface opened at the front side of the upper hook 66 is greater than that of the inclined surface opened at the rear side of the upper hook 66. The driving assembly includes a first rack plate 69 which is fixedly connected to the bottom end of the front side of a connecting rod 70. The connecting rod 70 is arranged inside a storage groove 71 which is opened at the bottom end of the energy storage cavity 57. A lower top block 72 is fixedly connected to the bottom end inside the storage groove 71. An inclined surface is opened at the left side of the lower top block 72. A guiding groove 73 is opened at the left side of the connecting rod 70. An upper top block 74 which is fixedly connected to the top end of the inner wall of the energy storage cavity 57 is slidably connected to the inside of the guiding groove 73. The top end of the connecting rod 70 is slidably connected to the outside of a sliding rod 75. The sliding rod 75 is fixedly connected to the inside of a sliding groove 76 which is opened at a position close to the rear side of the bottom end of the upper die 2. A second rack plate 77 is fixedly connected to the left side of the ejection plate 61. The second rack plate 77 is engaged with a transmission gear 78. The transmission gear 78 is rotatably connected to the inner wall of the energy storage cavity 57;

[0038] During operation, when the upper mold 2 moves downward, the sliding rod 75 drives the connecting rod 70 and the first rack plate 69 to move downward synchronously and insert into the interior of the storage groove 71. The initial state of the connecting rod 70 is on the right side of the sliding rod 75. During the downward movement of the connecting rod 70, the first rack plate 69 fixedly connected to the connecting rod 70 drives the transmission gear 78 to rotate counterclockwise, so that the transmission gear 78 drives the second rack plate 77 to move backward. The backward movement of the second rack plate 77 drives the fixedly connected pop-up plate 61 to move backward synchronously. During the backward movement of the pop-up plate 61, the second spring 64 is squeezed to cause the second spring 64 to produce elastic deformation, and the fixed connecting rod 70 is fixedly connected to the pop-up plate 61. The lower hook 65 at the top of the pop-up plate 61 moves with the pop-up plate 61, and the inclined surface on its rear side abuts with the inclined surface on the front side of the upper hook 66. Under the action of the two sets of inclined surfaces, the lower hook 65 pushes the upper hook 66 to rotate slightly clockwise, so that the upper hook 66 releases the obstruction of the lower hook 65. After the lower hook 65 passes, the upper hook 66 automatically falls back under the action of gravity. At this time, the inclined surface on the rear side of the upper hook 66 abuts with the inclined surface on the front side of the lower hook 65, blocking the lower hook 65, so that the lower hook 65 and the pop-up plate 61 cannot move forward. The second spring 64 keeps the energy stored. As the upper mold 2 continues to move downward, the connecting rod When the upper mold 2 moves upward after the plastic lunch box is formed, the upper top block 74 slides in the guide groove 73. When the upper top block 74 slides to the bottom of the guide groove 73, the inclined surface at the bottom end of the upper top block 74 pushes the connecting rod 70 to move rightward, so that the first rack plate 69 contacts the dial wheel 68 and dials the dial wheel 68 slightly. The slight rotation causes the dial wheel 68 to drive the rotating plate 67 to rotate synchronously, so that the upper hook 66 fixedly connected to the rotating plate 67 releases the obstruction to the lower hook 65 as the rotating plate 67 rotates. At this time, the pop-up plate 61 pops out of the energy storage chamber 57 from the ejection outlet 80 under the action of the restoring force of the second spring 64, and collides with the molded plastic lunch box. The buffer block 79 has the effect of buffering the collision, so as to prevent the plastic lunch box from being damaged by the impact of the pop-up plate 61. Under the action of the collision, the plastic lunch box is ejected forward from the top of the lower mold 3 to avoid affecting the subsequent processing of the plastic lunch box, so as to achieve the effect of uninterrupted injection molding of the plastic lunch box.

[0039] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
