Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically to a foam mold that is beneficial to foam molding. Background Art

[0002] A foam mold is a special tool for manufacturing foam plastic products. A foam mold usually refers to a mold used in the foam molding process. This mold is used to fill a foaming resin into its interior, and then the resin is melted by heating, and a gas-liquid saturated solution is formed therein. Subsequently, a large number of tiny bubbles are formed in the material through nucleation. These bubbles grow and solidify, and finally a foam plastic part with a specific shape and structure is made. Foam products are applied in various fields, such as industry, construction, and transportation. Foam appliances are widely used because of their good heat insulation performance, strong shock absorption performance, and moisture-proof performance.

[0003] As shown in the application document with the publication number CN213797736U in the prior art, it includes a cabinet body, an upper mold, and a lower mold. There are a through hole one and a through hole two on the upper surface of the cabinet body. There is a vertically movable feed pipe in the through hole one, and a vertically movable water inlet one in the through hole two. The lower end of the feed pipe is connected with a feed pipe, and the lower end of the feed pipe passes through the support plate and is connected with a four-way joint. There is a mold cavity in the upper mold, and the lower end of the four-way joint is connected to the upper end of the mold cavity. The water inlet one is connected with a water storage chamber one through a water pipe. There is a submersible pump one in the water storage chamber one. There is a water pipe in the upper mold. One end of the upper mold is connected with a water inlet pipe one and a water outlet pipe one. Both the water inlet pipe one and the water outlet pipe one are connected with the water pipe.

Sealing plates 4 are arranged inside both the front and rear ends of the top flow cavity 3. A telescopic rod 5 connecting to the top of the inner cavity of the top flow cavity 3 is installed on the top of the sealing plate 4. A spring 6 is sleeved outside the bottom end of the telescopic rod 5. A through hole 7 is formed on one side of the bottom of the top mold base 2 corresponding to the sealing plate 4. Two connecting cylinders 9 communicating with the bottom flow cavity 8 are installed on the top of the bottom mold base 1. The top end of the connecting cylinder 9 penetrates through the through hole 7 and extends into the top flow cavity 3, and the top end of the connecting cylinder 9 is in contact with the bottom of the sealing plate 4. A plurality of openings 10 distributed at intervals are formed outside the top end of the connecting cylinder 9.

[0025] As Figures 1-4 shown, a transfer box 11 is installed on the top of the top mold base 2. A telescopic pipe 12 is fixedly communicated with the top of the transfer box 11.
