Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder components, and more specifically, to an oil cylinder component used for a hot runner mold. Background Art

[0002] Hot runner molds are molds that use a heating device to keep the melt in the runner from solidifying. When using hot runner molds for mold manufacturing, the telescopic rod on the oil cylinder needs to be extended and retracted so that the fixed mold plate presses the end surface of the nozzle connecting plate before injection molding.

[0003] During use, the telescopic rod inside the oil cylinder needs to be extended and retracted back and forth. During the extension and retraction period, dust and debris from the outside will enter the oil cylinder through the telescopic rod, causing damage to the oil cylinder. The prior art only blocks the entry of dust by adding a gasket between the oil cylinder and the telescopic rod. After multiple uses, some dust will still enter the oil cylinder. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a cylinder assembly for a hot runner mold with a decontamination function.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model is further configured as follows: the clamping mechanism includes a plurality of connecting blocks, the outer sides of the connecting blocks are fixedly connected to the anti-blocking box, two round rods are welded in the upper and lower connecting blocks, two springs are fixedly connected on both sides of the round rods, a slide plate is welded on the other side of the spring, the slide plate is slidably connected to the round rod, and a clamping plate is installed on the slide plate.

[0008] The utility model is further configured as follows: a sealing plug is fixedly connected inside the anti-blocking box, and the sealing plug is slidably connected to the telescopic rod.

[0009] The utility model is further configured as follows: the dirt removal mechanism comprises a rotating shaft, the rotating shaft is rotatably connected to the clamping plate, a dirt removal wheel is fixedly connected to the rotating shaft, and a groove is provided in the clamping plate.

[0010] The utility model is further configured as follows: the mud scraping mechanism comprises an electric telescopic rod, one side of the electric telescopic rod is welded to the anti-blocking box, the other side of the electric telescopic rod is welded with a backing plate, and the backing plate is fixedly connected with a scraper.

[0011] The utility model is further configured as follows: a plurality of dirt removing blocks are installed on the dirt removing wheel, and the dirt removing blocks are abutted against the telescopic rod.

[0012] The utility model is further configured as follows: a base is welded on the left side of the main body, and a threaded hole is opened on the base.

[0013] The advantages of the utility model are:

[0014] 1. When the hot runner mold is used for injection molding, the fixed mold fixing plate is driven by the oil cylinder to press the nozzle connecting plate for injection molding. The telescopic rod in the oil cylinder reciprocates and retracts. The dirt on the telescopic rod can be removed by the rotation of the dirt removal wheel. The sealing block can prevent external dust from entering the oil cylinder and causing damage to the oil cylinder.
