Problems solved by technology

The thimble mechanism is an important part of the injection mold. It is mainly used in the injection mold to separate the product from the mold and stabilize the mold base. The thimble mechanism reciprocates, which is prone to wear and poor movement. In turn, the thimble will scratch the product, reducing the yield of the product and wasting costs

Embodiment Construction

[0013] The present invention is described below in conjunction with accompanying drawing.

[0014] Moisturizing thimble mechanism for mold base of the present invention, as attached figure 1 As shown, it includes a fixed base plate 1, a guide column 2 and a guide sleeve 3; a plurality of annular grooves 4 are provided on the outer circumference of the guide column 2; a solid lubricant is embedded in the annular groove 4; the solid lubricant The agent is graphite; the material of the guide column 2 is high-strength brass.

[0015] To further illustrate, there are three annular grooves, which are evenly distributed on the outer circumference of the guide post.

[0016] The self-lubricating thimble plate guide mechanism for the mold base of the present invention has a simple structure and a reasonable design. The column makes the solid lubricant rub against the mold base through frictional heat, forming an excellent condition for oil and powder coexistence lubrication, which no...

Abstract

The invention discloses a self-lubricating centre plate guide mechanism for mold bases. The self-lubricating centre plate guide mechanism comprises a fixed bottom plate, a guide column and a guide sleeve; a plurality of annular grooves are formed in the outer periphery of the guide column; solid lubricants are embedded into the annular grooves and are made of graphite; the guide sleeve is made of high-strength brass. The self-lubricating centre plate guide mechanism for the mold bases is simple in structure and reasonable in design and is a high-performance lubrication product with the graphite embedded into the guide column on the basis of the guide column made of high-strength brass. In the use process, the guide column enables the solid lubricants to rub against the mold bases through the friction heat, the excellent condition of both oil lubrication and powder lubrication is formed, the centre plate guide mechanism is protected against abrasion, the solid lubrication property is permanent, the hardness and the abrasive resistance of the centre plate guide mechanism are effectively improved, and the service life of the centre plate guide mechanism is greatly prolonged.

Description

technical field [0001] The invention relates to a component for a mold base, in particular to a self-lubricating thimble plate guide mechanism for a mold base. Background technique [0002] With the continuous improvement of technology and the rapid development of the plastic product industry, the diversified structure of various plastic parts is becoming more and more complex, the quality requirements are becoming more and more stringent, the requirements for the plastic product industry are getting higher and higher, and the competition is also increasing. The more intense it is, how to ensure that there are no abnormalities in the production process of similar plastic products, and to maximize the effective and stable production cycle of product processing. The thimble mechanism is an important part of the injection mold. It is mainly used in the injection mold to separate the product from the mold and stabilize the mold base. The thimble mechanism reciprocates, which is ...
