Description

Technical Field

[0001] The invention relates to the technical field of plastic molds, in particular to a plastic mold with small insert cooling. Background Art

[0002] A plastic mold with small insert cooling is a mold used to produce plastic products. It achieves rapid molding and cooling of plastic products by setting small inserts (i.e., embedded parts) and a cooling system inside the mold.

[0003] Today's plastic molds with small insert cooling have a single cooling method, and most of them are set on the outer surface of the mold, which may cause uneven cooling for hollow castings. Summary of the invention

[0004] The object of the present invention is to provide a plastic mold with small insert cooling to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a plastic mold with small insert cooling, comprising a cooling hood, an upper mold body, a protective cover and a lower mold, the upper surface of the upper mold body is sleeved with the cooling hood, and the lower surface of the upper mold body is plugged with a fixing cover, the lower surface of the lower mold is sleeved with the fixing hood, and the upper surface of the lower mold is plugged with a protective cover.

[0006] When using a plastic mold with small insert cooling in the technical solution, if the insert is hollow, remove the fixing block and the connecting block, insert the fixing cover into the lower surface of the upper mold body, and insert the protective cover into the upper surface of the lower mold. After the injection molding is completed, the gap between the fixing cover and the protective cover can be used to cool the inside of the hollow insert, thereby ensuring uniform cooling.

[0007] Preferably, a feed pipe is connected to one outer end surface of the cooling cover, and a feed valve is threadedly connected to the outer surface of the feed pipe. The feed valve is threadedly connected to the feed pipe to accurately control the flow of a fluid (such as coolant, gas or other medium).

[0008] Preferably, a fixing plate is fixed to one outer end surface of the cooling cover, and a supporting plate is fixed to one outer end surface of the fixing cover. The fixing plate and the supporting plate are fixedly connected to the cooling cover, which can significantly enhance the overall structural stability of the cooling cover.

[0009] Preferably, the fixing plate and the support plate are internally threadedly connected with a locking rod, and the outer end surfaces on both sides of the locking rod are threadedly connected with nuts. Threaded connection is a simple and reliable connection method. Through the cooperation of the locking rod with the threads of the fixing plate and the support plate, a large axial force can be generated, thereby ensuring the firmness of the connection.

[0010] Preferably, one side outer end surface of the fixed cover is connected to a discharge pipe, and the outer surface of the discharge pipe is threadedly connected to a discharge valve. The discharge valve is threadedly connected to the discharge pipe, and the flow rate and switch of the material can be accurately controlled as needed to ensure that the output of the material meets the process requirements.

[0011] Preferably, a fixing block is inserted into the lower surface of the upper mold body, and a mounting cover is inserted into the upper surface of the fixing block. The mounting cover is inserted into the upper surface of the fixing block, further increasing the structural strength of the mold and providing additional protection for the mold.

[0012] Preferably, a connection block is inserted into the upper surface of the lower mold, and a support cover is inserted into the lower surface of the connection block. The connection block is inserted into the upper surface of the lower mold, and the support cover is inserted into the lower surface of the connection block. This layered plug-in structure can significantly enhance the overall structural stability of the mold.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention achieves the effect of ensuring uniform cooling by arranging a fixing block, a connecting block and a protective cover. If the insert is hollow, the fixing block and the connecting block are removed, the fixing cover is plugged into the lower surface of the upper mold body, and the protective cover is plugged into the upper surface of the lower mold. After the injection molding is completed, the gap between the fixing cover and the protective cover can be used to cool the inside of the hollow insert, thereby ensuring uniform cooling.

[0014] The present invention achieves the effect of improving cooling efficiency by arranging a cooling hood, a fixed hood and a feed pipe. The cooling hood is sleeved on the upper surface of the upper mold body and can directly cool the upper mold body, ensuring that the upper mold body is quickly cooled during high-temperature injection molding and shortening the molding cycle. The fixed hood is sleeved on the lower surface of the lower mold and also plays a cooling role. This upper and lower double cooling design can more evenly control the temperature of the upper mold body and the lower mold and improve the cooling efficiency. The feed pipe is connected to the cooling hood for conveying coolant. The feed valve can accurately control the flow rate and switch of the coolant to ensure the stability and controllability of the cooling process. The discharge pipe is connected to the fixed hood for discharging the coolant. The discharge valve can also accurately control the flow rate to ensure smooth circulation of the coolant and avoid accumulation or leakage of the coolant. Through a uniform cooling system and good protection of the upper mold body and the lower mold, it can be ensured that the upper mold body and the lower mold maintain good dimensional accuracy and surface quality during use, thereby improving the quality of the product.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0020] Based on a plastic mold with small insert cooling according to Example 1, if the insert is hollow, remove the fixing block 15 and the connecting block 16, insert the fixing cover 3 into the lower surface of the upper mold body 2, and insert the protective cover 4 into the upper surface of the lower mold 5. After the injection molding is completed, the gap between the fixing cover 3 and the protective cover 4 can be used to cool the inside of the hollow insert to ensure uniform cooling.

[0021] The fixing plate 9 and the support plate 12 are connected to the locking rod 10 by threads and then locked by the nut 11. This design significantly enhances the structural stability of the cooling cover 1 and the fixing cover 6.
