Description

Technical Field

[0001] This utility model belongs to the field of rapid plastic production technology, specifically a rapidly cooling injection mold. Background Technology

[0002] A plastic mold is a tool used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product. Injection molds are classified into two types according to their molding characteristics: thermosetting plastic molds and thermoplastic plastic molds. Existing injection molds have a relatively slow cooling rate during use, lack good cooling devices, which reduces production efficiency, prolongs processing time, and makes them difficult to disassemble after processing, causing inconvenience in use.

[0003] Meanwhile, a rapidly cooling injection mold with the publication number CN109130091A is disclosed, including a lower mold and an upper mold. A first rectangular groove is opened on one surface of the lower mold; a first water storage tank is opened on the inner surface of the lower mold; two first water inlet pipes are provided on one surface of the lower mold; a second rectangular groove is opened on one surface of the upper mold; a second water storage tank is opened on the inner surface of the upper mold; two first through holes are opened on one surface of the upper mold; the inner surface of the first through hole is sleeved with the peripheral side of the first water inlet pipe.

[0004] The aforementioned rapid-cooling injection mold does not collect the cooled water during use, thus wasting water resources. Furthermore, it does not filter impurities in the cooling water, which can easily clog the cooling pipes, making maintenance more difficult, resulting in longer downtime and reduced production efficiency.

[0005] Therefore, a rapidly cooling injection mold is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an injection mold that can be rapidly cooled, which has the advantages of secondary cooling, enabling the mold to cool down faster, filtering impurities in the water, and reducing the blockage of cooling pipes.

[0011] By adopting the above technical solution, the heat dissipation of the upper mold can be accelerated through the heat sink and fan.

[0012] Preferably, a water tank is fixedly installed on the left side of the upper end face of the base plate, a water pump is fixedly installed in the middle of the upper end face of the base plate, a filter box is fixedly installed on the left side of the water pump and the filter box is located on the right side of the water tank, a filter screen is fixedly installed inside the filter box, and a baffle is fixedly installed on the front end face of the filter box.

[0013] By adopting the above technical solution, impurities in the water can be filtered out through the filter screen to prevent clogging of the cooling pipes during cooling.

[0014] Preferably, a water distribution plate is fixedly provided on the left side of the water pump, a connection port is fixedly provided behind the water distribution plate, and a connector is fixedly provided on the outside of the connection port.

[0017] By adopting the above technical solution, the water pump can collect the cooled water in the cooling pipe and perform secondary heat dissipation.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses a transfer box to collect warm water after heat dissipation. A square plate can fix a fan to prevent it from deviating from the center during operation. The fan can cool the water in the transfer box. The nozzle can spray the water in the transfer box to achieve secondary heat dissipation and make the mold cool down faster.

[0020] 2. This utility model uses heat sinks to absorb heat from the upper mold. The motor and fan can dissipate heat from the heat sinks, allowing the mold to cool down more quickly. The water pump collects the cooled water from the cooling pipes, allowing new cooling water to enter the cooling pipes and cool the mold. The filter box reduces impurities in the water and prevents clogging of the cooling pipes. Attached Figure Description
