Description

Technical Field

[0001] The utility model relates to the technical field of cooling of foaming molds, in particular to a cooling mechanism for a foaming mold. Background Technique

[0002] A foaming mold is a special mold for manufacturing foam products. A foaming mold is usually divided into a movable mold and a fixed mold. When the two are combined, a cavity of the mold is formed. In this cavity, a heating source is used to heat the mixture of the foaming agent and the plastic raw material in the mold. As the temperature rises, the foaming agent begins to decompose to generate gas. These gases are mixed with the plastic raw material and expand to fill the entire mold cavity, thereby producing a foaming product. After the foaming process is completed, it is necessary to cool the foaming product. Existing foaming molds integrate a circulation channel inside the fixed mold. These channels are connected to an external cooling source through cooling pipes on the outer wall of the fixed mold. The traditional operation method is to introduce a coolant into these circulation channels and use the flow of the coolant to absorb and carry away the heat inside the fixed mold, thereby realizing the cooling of the product;

[0003] The method of introducing a coolant into the circulation channel can only cool the part of the foaming product in contact with the inner wall of the fixed mold, and cannot directly act on the outer surface of the foaming product, resulting in insufficient surface cooling of the product and low overall cooling efficiency.

[0004] To solve the above problems, a cooling mechanism for a foaming mold is proposed in this application. Content of the Utility Model

[0005] Based on the technical problems existing in the background technique, the utility model proposes a cooling mechanism for a foaming mold.

[0006] A cooling mechanism for a foaming mold proposed by the utility model includes a cooling water tank;

[0007] A fixed mold is installed on the cooling water tank, and a movable mold that can be separated from the fixed mold is arranged on the fixed mold;

[0008] A circulation channel is opened in the fixed mold. An inlet pipe and an outlet pipe communicated with the circulation channel are respectively connected to both sides of the fixed mold. The end of the outlet pipe away from the fixed mold is communicated with the cooling water tank. The end of the inlet pipe away from the fixed mold is communicated with an overcurrent air blowing member, and a water supply member for guiding water into the overcurrent air blowing member is installed on the cooling water tank;

[0009] A tubular air blowing member for blowing air on the foaming product in the fixed mold is sleeved on the movable mold, and the overcurrent air blowing member and the tubular air blowing member are communicated through a duct.

[0010] Preferably, the overcurrent air blowing member includes a water passing cylinder connected to the end of the water inlet pipe away from the fixed mold. An overcurrent chamber communicating with the water inlet pipe is formed in the water passing cylinder. A wind cylinder is installed on the top of the water passing cylinder, and a wind chamber is formed in the wind cylinder. A fan blowing portion is rotatably installed in the overcurrent chamber, and the top end of the fan blowing portion rotatably passes through the bottom of the wind cylinder and extends into it.

[0011] Preferably, the fan blowing portion includes a rotating rod vertically arranged in the overcurrent chamber. The bottom end of the rotating rod is rotatably connected to the bottom inside the water passing cylinder. The top end of the rotating rod rotatably passes through the top of the water passing cylinder and the bottom of the wind cylinder and extends into it. Axial flow blades are installed at both ends of the rotating rod, and the two axial flow blades are respectively located in the overcurrent chamber and the wind chamber.

[0012] Preferably, the water supply member includes a water pump and a water supply pipe. The water pump is installed at the bottom of the cooling water tank and communicates with it. The two ends of the water supply pipe are respectively connected to the water inlet end of the water pump and the side of the water passing cylinder away from the water inlet pipe, and the water supply pipe communicates with the overcurrent chamber.

[0013] Preferably, the tubular air blowing member includes a frame-shaped air blowing pipe fixedly sleeved on the moving mold. A plurality of blowing nozzles arranged at intervals and facing the middle of the fixed mold are connected to the bottom of the frame-shaped air blowing pipe. The two ends of the air guide pipe are respectively connected to one side of the frame-shaped air blowing pipe and the top of the wind cylinder, and the air guide pipe communicates with the frame-shaped air blowing pipe and the wind chamber respectively.

[0014] The above technical solution of the present invention has the following beneficial technical effects:

[0015] By providing the overcurrent air blowing member and the tubular air blowing member, when the product is molded, the cold water in the cooling water tank can be guided to the overcurrent air blowing member through the water supply member. The cold water entering the overcurrent air blowing member is guided to the circulation channel formed in the cooling water tank along the water inlet pipe under pressure, and then flows back to the cooling water tank along the water outlet pipe to form a reciprocating cycle. When the water flows through the overcurrent air blowing member, it can drive its operation and generate wind, which is guided to the tubular air blowing member along the air guide pipe, so that the moving mold can be separated from the fixed mold. The surface of the foaming product can be blown by the tubular air blowing member to play a role in air cooling. This structure utilizes the water cooling cycle of the mold itself to drive the operation of the overcurrent air blowing member, realizing air cooling of the surface of the foaming product, enabling the foaming product to be cooled more fully and improving the cooling efficiency.

[0020] As Figure 1 shown in Figure 2 a cooling mechanism for a foaming mold proposed by the present utility model includes a cooling water tank 1;

[0021] In this embodiment, a fixed mold 2 is installed on the cooling water tank 1, and a moving mold 3 that can be separated from the fixed mold 2 is arranged on the fixed mold 2.

[0022] In this embodiment, a circulation channel is opened in the fixed mold 2. The two sides of the fixed mold 2 are respectively connected with a water inlet pipe 4 and a water outlet pipe 5 that communicate with the circulation channel. The end of the water outlet pipe 5 far from the fixed mold 2 is communicated with the cooling water tank 1, and the end of the water inlet pipe 4 far from the fixed mold 2 is communicated with an overcurrent fan component 6. The overcurrent fan component 6 includes a water passing cylinder 61. The water passing cylinder 61 is connected to the end of the water inlet pipe 4 far from the fixed mold 2. An overcurrent chamber communicating with the water inlet pipe 4 is opened in the water passing cylinder 61. An air duct 62 is installed on the top of the water passing cylinder 61. An air chamber is opened in the air duct 62. A fan part 63 is rotatably installed in the overcurrent chamber, and the top end of the fan part 63 rotatably passes through the bottom of the air duct 62 and extends into it. The fan part 63 includes a rotating rod 631. The rotating rod 631 is vertically arranged in the overcurrent chamber, and the bottom end of the rotating rod 631 is rotatably connected to the bottom in the water passing cylinder 61. The top end of the rotating rod 631 rotatably passes through the top of the water passing cylinder 61 and the bottom of the air duct 62 and extends into it. Axial flow blades 632 are installed at both ends of the rotating rod 631, and the two axial flow blades 632 are respectively located in the overcurrent chamber and the air chamber.

[0023] In this embodiment, a water supply component 7 for guiding water into the overcurrent fan component 6 is installed on the cooling water tank 1. The water supply component 7 includes a water pump 71 and a water supply pipe 72. The water pump 71 is installed at the bottom of the cooling water tank 1 and communicates with it. The two ends of the water supply pipe 72 are respectively connected to the water inlet end of the water pump 71 and the side of the water passing cylinder 61 far from the water inlet pipe 4, and the water supply pipe 72 communicates with the overcurrent chamber.

[0024] In this embodiment, a tubular blowing member 8 for blowing air on the foamed product in the fixed mold 2 is sleeved on the moving mold 3, and the cross-flow air blowing member 6 is communicated with the tubular blowing member 8 through a duct 9. The tubular blowing member 8 includes a frame-shaped blowing duct 81 which is fixedly sleeved on the moving mold 3.
