[0002] TPO elastomer is a thermoplastic polyolefin elastomer material. TPO elastomer is mainly made of rubber and polyolefin. This blending system allows TPO elastomer to maintain the softness, elasticity and chemical corrosion resistance of rubber while also having the easy processing and recyclability of thermoplastics.

[0003] A molding machine is a device specially used to process plastic or other plastic materials into specific shapes and sizes. For TPO elastomers, they are usually provided to the molding machine in the form of granules or powders, and then go through processes such as heating, melting, injection, and cooling to finally form the desired product.

[0004] When using a molding machine to form a TPO elastomer through extrusion of a mold, the mold needs to be cooled to improve the production efficiency of the TPO elastomer. The mold can be cooled through a cooling channel, but the cooling channels of the upper mold and the lower mold in the TPO molding machine currently on the market are often not connected. In this way, it is necessary to design multiple cooling channels for cooling. The lines are too complicated and multiple refrigeration mechanisms are required, which will generate a lot of energy consumption and increase the production cost of the TPO elastomer.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-6 A molding machine for producing TPO elastomers includes a table body 1, an auger transmission mechanism 2 is arranged on one side above the table body 1, an upper mold 6 and a lower mold 7 are arranged on the other side above the table body 1, the upper mold 6 is located above the lower mold 7 and moves vertically, and the auger transmission mechanism 2 is connected to the mold cavity of the lower mold 7 through an injection tube. An upper cooling pipe 61 and a lower cooling pipe 71 are fixedly arranged inside the upper mold 6 and the lower mold 7, respectively, a plurality of upper connecting pipes 611 are arranged vertically downward on one side of the upper cooling pipe 61, and a plurality of lower connecting pipes 711 are arranged vertically upward on one side of the lower cooling pipe 71, and the upper connecting pipes 611 are adapted to be connected with the lower connecting pipes 711.

[0023] Among them, a top plate 3 is fixedly arranged on the table body 1 above the upper mold 6 through a plurality of support columns, and a cylinder 4 is fixedly arranged on the top of the top plate 3. The upper mold 6 can be driven downward to be extruded by the cylinder 4, and it is worth noting that the specific structure and working mode of the cylinder 4 are both existing technologies currently disclosed on the market, which are common knowledge well known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0024] The top extension end of the cylinder 4 vertically passes through the top plate 3 and is fixedly connected to the upper mold 6. A plurality of guide posts 5 are fixedly and vertically arranged on the upper part of the table body 1. The other ends of the guide posts 5 are connected to the top plate 3, and the upper mold 6 moves on the guide posts 5. The arrangement of the guide posts 5 can ensure that the upper mold 6 remains stable during the movement.

[0025] Among them, the upper connecting pipe 611 and the lower connecting pipe 711 extend from one side of the upper mold 6 and the lower mold 7 respectively, and the upper cooling pipe 61 and the lower cooling pipe 71 extend from the other side of the upper mold 6 and the lower mold 7 respectively. The ends of the upper cooling pipe 61 and the lower cooling pipe 71 extend from the upper mold 6 and the lower mold 7 respectively, and the extended parts are connected to the external pump body and the refrigerator through a corrugated hose. When cooling, cold air is produced by the refrigerator, and then the cold air enters the upper cooling pipe 61 through the lower cooling pipe 71, and then flows back to the cooling machine through the upper cooling pipe 61 to form a cycle. It is also worth noting that the specific structure of the refrigerator and the pump body and their working methods are all existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0026] The contacting parts of the upper connecting tube 611 and the lower connecting tube 711 are both provided with sealing sleeves, and the inner wall of the lower connecting tube 711 is fixedly provided with a sealing member 712. The sealing sleeve and the sealing member 712 ensure the sealing performance when the upper connecting tube 611 and the lower connecting tube 711 are in contact.

[0027] Among them, the lower mold 7 is fixedly provided with a reinforcing member 72 on the outer side of the protruding portion of the lower connecting tube 711, and the upper mold 6 is adapted to open a reinforcing cavity 62 corresponding to the reinforcing member 72. When the upper mold 6 is in contact with the lower mold 7, the reinforcing member 72 is adapted to enter the reinforcing cavity 62, and because the reinforcing member 72 is located on the outer side of the lower connecting tube 711, the sealing performance of the upper connecting tube 611 and the lower connecting tube 711 when in contact can be further enhanced.

[0028] In this embodiment, a feed pipe is provided above the auger transmission mechanism 2, and the raw material enters the auger transmission mechanism 2 through the feed pipe, and then is injected into the mold cavity between the upper mold 6 and the lower mold 7 through the injection tube, and then after cooling, the TPO elastomer can be produced by extrusion between the upper mold 6 and the lower mold 7. It is worth noting that the specific structure of the mold cavity in the auger transmission mechanism 2, the upper mold 6 and the lower mold 7 and their working methods are all existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0029] Furthermore, during injection molding, since the upper mold 6 and the lower mold 7 are in contact with each other, the reinforcing member 72 is located in the reinforcing cavity 62, and the upper connecting pipe 611 and the lower connecting pipe 711 are in contact and connected with each other, the user can inject cold air into the lower cooling pipe 61 through an external refrigerator, and the cooling enters from the lower cooling pipe 61, passes through the lower connecting pipe 711, the upper connecting pipe 611, and the upper cooling pipe 71 in sequence, and then flows back to the refrigerator, thereby realizing the circulation of the cooling pipeline. In this way, there is no need to set up multiple cooling channels and refrigeration mechanisms, saving costs.

[0030] In the utility model, the production of TPO elastomer can be achieved through the extrusion between the upper mold 6 and the lower mold 7. During the pressing process between the upper mold 6 and the lower mold 7, the upper cooling pipe 61, the upper connecting pipe 611, the lower cooling pipe 71, and the lower connecting pipe 711 are connected, so that the mold can be cooled by the flow of cold air in the pipeline. Only one cooling channel is required, which saves costs and improves economic benefits.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
