Description

Technical Field

[0001] The utility model belongs to the technical field of multi-cavity runner balance molds, and more specifically, particularly relates to a multi-cavity runner balance mold. Background Technique

[0002] The use of multi-cavity injection molding for plastic products is becoming more and more common. The most important factor to consider in the design of such molds is filling balance. In multi-cavity injection molding molds, the runner system is usually designed in an "H" shape or a "king" shape. The runners from the injection nozzle to each cavity in the "H" type runner system and the "king" type runner system are geometrically completely symmetrical, so they are also called "geometric balance" or "natural balance" runner system designs.

[0003] Based on the above, the inventor found the following problems: After the current plastic products are molded in the multi-cavity runner balance mold, the staff needs to use tools to loosen the bolts one by one to disassemble the upper part of the mold, and then demold the molded products. This method reduces work efficiency. At the same time, the multi-cavity runner balance mold will be worn after long-term use, which has a certain impact on the accuracy of subsequent products. The existing replacement method is to replace the whole, which increases the replacement cost.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a multi-cavity runner balance mold is provided with the expectation of achieving a more practical value. Content of the Utility Model

[0005] The purpose and effect of a multi-cavity runner balance mold of the utility model are achieved by the following specific technical means:

[0006] A multi-cavity runner balance mold includes a connecting plate. A cooling device is installed inside the connecting plate. A molding diversion core plate is installed on the top of the connecting plate. A shunt plate is installed on the top of the molding diversion core plate. A pin assembly is installed between the shunt plate and the molding diversion core plate. A glue injection port is installed on the top of the shunt plate. An inclined hole communicating with the glue injection port is opened inside the shunt plate. A groove is opened inside the molding diversion core plate. A group of support plates are installed on both sides of the groove. A mold body is installed on the top of the support plates. An installation assembly is installed between the mold body and the support plates.

[0007] Further, the pin assembly includes two chambers opened inside the shunt plate. A spring is installed inside the chamber. A limiting plate is installed on one side of the spring. A handle is installed on the top of the limiting plate. A clamping block is installed on the bottom of the limiting plate. An installation slot is opened inside the molding diversion core plate. A clamping slot is opened on one side of the installation slot. The clamping slot is matched with the clamping block.

[0008] Further, the installation component includes two sets of threaded holes opened in the support plate and the mold body. Bolts are installed inside the threaded holes, and the bolts match the threaded holes.

[0009] Further, the number of the card slots corresponds to that of the card blocks.

[0010] Further, a transverse runner is opened at the center of the mold body. Three shunt runners are sequentially opened at the opening of the transverse runner, and injection ports are opened at both ends of each shunt runner.

[0011] Further, the inclined holes are located directly above the transverse runner.

[0012] Further, the transverse runner and the shunt runners are in the shape of the Chinese character 'Wang'.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the combined use of the spring, the limit plate, the handle, the installation groove, the card slot and the card block, when it is necessary to demold the formed product, pull the handle. Under the expansion and contraction of the spring, drive the limit plate to move into the chamber, so that the card block can be disengaged from the card slot. The card block is in the installation groove, and then the shunt plate can be separated from the formed diversion die core plate, and the formed product can be taken out from the mold body. Through the above design, the demolding speed is greatly improved, the work efficiency is further improved, and at the same time, the working intensity of the staff is reduced.

[0015] Through the combined use of the support plate, the mold body, the threaded holes and the bolts, due to the long-term use of the multi-cavity runner balance mold, the mold body needs to be replaced. The staff twists the bolts to disengage the bolts from the threaded holes, and then the mold body can be taken out of the groove. Through the above design, it is convenient to replace the worn mold body, the accuracy and quality of the product are greatly improved, and at the same time, mold bodies of different models can be installed, further improving the practicability.
