Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to a fast cooling mold for buckle injection molding. Background Art
[0002] An injection mold is a mold used to produce plastic products. It forms a product with a specific shape by injecting molten plastic material into the mold and solidifying it under pressure and cooling. The structure of the injection mold usually includes a high-precision mold and a mold holder, which can manufacture plastic products of various shapes and sizes.
[0003] In order to speed up the cooling of plastic parts, some injection molds in the prior art will dissipate heat through cooling fans. However, the newly injected plastic parts are often placed in the mold cavity with less contact area with the external environment. Therefore, the wind from the cooling fan can only cool the local surface of the plastic parts, reducing the cooling efficiency. In view of this, we propose a rapid cooling mold for fastener injection molding. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet actual needs, and provide a fast cooling mold for fastener injection molding to solve the technical problem that some injection molds in the prior art will dissipate heat through a heat dissipation fan in order to speed up the cooling of plastic parts. However, the newly injected plastic parts are often placed in the mold cavity and have a small contact area with the external environment. Therefore, the wind from the heat dissipation fan can only cool the local surface of the plastic parts, reducing the cooling efficiency.
[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a rapid cooling mold for fastener injection molding, including a base, a fastener die is provided on the top of the base, two groups of hydraulic cylinders are provided on the surface of the fastener die, the upper end of the hydraulic cylinder is connected to a movable seat, a fluid channel is provided in the middle of the movable seat, a liquid inlet is provided inside the fluid channel, a fastener punch is connected to the bottom of the liquid inlet, an auxiliary mechanism is provided on the side of the movable seat, and a cooling mechanism is provided inside the fastener die.
[0006] Preferably, the auxiliary mechanism comprises an electric push rod, a movable end of the electric push rod is connected to a long rod, and an end of the long rod away from the electric push rod is connected to a baffle.
[0007] Preferably, the long rod is movably engaged in the movable seat, and the baffle forms a telescopic structure through the long rod and the electric push rod.
[0008] Preferably, the bottom of the baffle is fitted with the top of the liquid inlet, and the liquid inlet is connected to the buckle convex mold.
[0009] Preferably, the cooling mechanism comprises a liquid inlet pipe, the end of the liquid inlet pipe is connected to an annular pipe, adjacent annular pipes are connected via an inclined pipe, and the side of the top annular pipe is connected to a liquid outlet pipe.
[0010] Preferably, the liquid inlet pipe is connected to the liquid outlet pipe through an annular pipe and an inclined pipe.
[0011] Preferably, the annular tube is uniformly surrounded inside the fastener die, and the distribution state of the annular tube matches the shape of the groove cavity of the fastener die.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model guides external condensed water into the liquid inlet pipe. Since the liquid inlet pipe is connected with the liquid outlet pipe through the annular pipe and the inclined pipe, the condensed water can be filled in the inside of each layer of the annular pipe from bottom to top, thereby effectively cooling and dissipating the heat around the groove cavity of the fastener die, thereby accelerating the cooling of the fastener plastic parts. The uniform surrounding of the annular pipe inside the fastener die improves the cooling effect. The condensed water flowing out of the liquid outlet pipe can be uniformly collected and continued to condense, and repeatedly poured into the liquid inlet pipe, reducing the waste of water resources and realizing the recycling of water resources.
[0014] 2. When the utility model is performing injection molding, the electric push rod effectively drives the long rod and the baffle to move horizontally, thereby opening the fluid channel, making it convenient for the external injection port to inject the injection melt into the liquid inlet, and then the electric push rod drives the long rod and the baffle to return to their positions, effectively blocking the liquid inlet, thereby closing the fluid channel, preventing the injection melt that has been injected into the mold from continuing to contact with the external injection port, reducing the impact of low temperature on the external injection port, and reducing the possibility of solidification of the melt at the end of the external injection port.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0024] A fast cooling mold for buckle injection molding, see Figures 1 to 5 , including a base 1, a fastener die 2 is provided on the top of the base 1, two groups of hydraulic cylinders 3 are provided on the surface of the fastener die 2, the upper end of the hydraulic cylinder 3 is connected with a movable seat 4, a fluid channel 5 is provided in the middle of the movable seat 4, a liquid inlet 6 is provided inside the fluid channel 5, a fastener punch 7 is connected to the bottom of the liquid inlet 6, an auxiliary mechanism 8 is provided on the side of the movable seat 4, and a cooling mechanism 9 is provided inside the fastener die 2.
[0025] It is worth mentioning that the auxiliary mechanism 8 includes an electric push rod 801, a movable end of the electric push rod 801 is connected to a long rod 802, and an end of the long rod 802 away from the electric push rod 801 is connected to a baffle 803. Furthermore, the long rod 802 is movably engaged in the movable seat 4, and the baffle 803 forms a telescopic structure with the electric push rod 801 through the long rod 802. Furthermore, the bottom of the baffle 803 is in contact with the top of the liquid inlet 6, and the liquid inlet 6 is connected to the fastener punch 7. When the utility model performs injection molding, the electric push rod 801 effectively drives the long rod 802 and the baffle 803 to move horizontally, thereby opening the fluid channel 5, making it convenient for the external injection port to inject the injection melt into the liquid inlet 6. After that, the electric push rod 801 drives the long rod 802 and the baffle 803 to return to their original positions, effectively blocking the liquid inlet 6, thereby closing the fluid channel 5, preventing the injection melt that has been injected into the mold from continuing to contact with the external injection port, reducing the impact of low temperature on the external injection port, and reducing the possibility of solidification of the melt at the end of the external injection port.
[0026] It is worth noting that the cooling mechanism 9 includes a liquid inlet pipe 901, the end of which is connected to a ring-shaped pipe 902, adjacent ring-shaped pipes 902 are connected via an inclined pipe 903, and the side of the top ring-shaped pipe 902 is connected to a liquid outlet pipe 904. Furthermore, the liquid inlet pipe 901 is connected to the liquid outlet pipe 904 via the ring-shaped pipe 902 and the inclined pipe 903. Furthermore, the ring-shaped pipe 902 is evenly surrounded inside the fastener die 2, and the distribution state of the ring-shaped pipe 902 matches the shape of the groove cavity of the fastener die 2. The utility model guides external condensed water into the liquid inlet pipe 901. Since the liquid inlet pipe 901 is connected with the liquid outlet pipe 904 through the annular pipe 902 and the inclined pipe 903, the condensed water can be filled in the inside of each layer of the annular pipe 902 from bottom to top, thereby effectively cooling the surrounding of the groove cavity of the fastener die 2, thereby accelerating the cooling of the fastener plastic parts. The uniform surrounding of the annular pipe 902 inside the fastener die 2 improves the cooling effect. The condensed water flowing out of the liquid outlet pipe 904 can be uniformly collected and continued to condense, and repeatedly poured into the liquid inlet pipe 901, thereby reducing the waste of water resources and realizing the recycling of water resources.
[0027] Working principle: During injection molding, the electric push rod 801 drives the long rod 802 and the baffle 803 to move horizontally, thereby opening the fluid channel 5, so that the external injection port injects the injection melt into the liquid inlet 6. Then, the electric push rod 801 drives the long rod 802 and the baffle 803 to return to their original positions, blocking the liquid inlet 6, thereby closing the fluid channel 5, preventing the injection melt that has been injected into the mold from continuing to contact with the external injection port, reducing the impact of low temperature on the external injection port, and then guiding the external condensed water to the external injection port. In the liquid inlet pipe 901, since the liquid inlet pipe 901 is connected with the liquid outlet pipe 904 through the annular pipe 902 and the inclined pipe 903, the condensed water can be filled in the inside of each layer of the annular pipe 902 from bottom to top, thereby cooling the surrounding of the groove cavity of the fastener die 2, thereby accelerating the cooling of the fastener plastic parts. The condensed water flowing out of the liquid outlet pipe 904 can be collected and continued to condense, and repeatedly poured into the liquid inlet pipe 901, reducing the waste of water resources and realizing the recycling of water resources.
