The development of my country’s mold industry is obvious to all. Although there are still many problems that cannot be ignored, its development is unstoppable. The development of the industry is inseparable from its various branch industries. An important part of the mold is mold spare parts.
Mold parts are the components and basic components of the mold. A complete mold consists of a mold base, guide components, punching components, nitrogen gas springs, pneumatic components, fixed seats, sliding and wear-resistant guide plates, wedge mechanisms, etc. It is assembled from parts and functional components. Mold accessories are widely used in various types of plastic molds, stamping molds, automobiles, electrical and aviation fields.
1,Do you know the main characteristics of mold accessories?
Wear resistance: When the blank plastically degenerates in the mold cavity, it both flows and slides along the cavity surface, causing severe friction between the cavity surface and the blank, causing the mold to fail due to wear. Therefore, the wear resistance of materials is one of the most important properties of mold accessories.
Strong toughness: Most of the working conditions of molds are not good, and some often bear large impact loads, resulting in brittle fracture. In order to prevent the mold parts from suddenly breaking during operation, the mold parts must have high strength and toughness. The toughness of mold parts mainly depends on the carbon content, grain size and organizational state of the material.
Corrosion resistance: When the plastic mold is working, due to the presence of chlorine, fluorine and other elements in the plastic, highly corrosive gases such as HCL and HF are decomposed after being heated, eroding the surface of the mold cavity, increasing its surface roughness, and aggravating wear and failure.
Corrosion resistance, wear resistance and strength and toughness are the three major characteristics of mold parts. However, the current production requirements are becoming more and more stringent. These three characteristics alone can no longer meet the application of mold parts in production. Then, new mold parts are still needed. What features are required?
Fatigue fracture resistance Fatigue fracture resistance is a property that all new mold parts have now. Because in the high-intensity production process, mold parts are prone to fatigue fracture under long-term force, so they have fatigue fracture resistance. Mold parts are now very important, and the fatigue fracture resistance of mold parts depends on its strength, toughness, hardness and the process and materials used to make the mold parts.
High temperature resistance is a basic performance that is currently required for mold parts. Because molds are constantly entering and exiting the production line during the production process, high temperature work will weaken the hardness and strength of mold parts. Therefore, molds with tempering resistance stability Accessories can ensure the stability of the production process and the high quality of the product in high temperature environments.
2,Do you know what common mold accessories are?
Mold parts are divided into automotive plastic mold parts, non-standard mold parts, plastic mold parts, and metal stamping mold parts. Mold accessories is the full name of a category, which can be subdivided into hundreds of parts.
(1)Products include: inclined top device, air top, positioning beads, resin shutter, date stamp, mold locking buckle, limit clamp, secondary ejection, reset mechanism, mold counter, auxiliary device, positioning parts, cooling parts, Steel ball sleeves, guide column guide sleeves, inclined roof devices, air caps, etc.
(2)Automotive plastic mold parts
Cylinder pin: used to form the column hole of the product, used with the cylinder, not for demoulding;
support column (support head): supports the B plate, which is deformed due to pressure during injection molding;
garbage nail: supports the ejector pin Plate, due to its small area, can prevent garbage from accumulating on it and causing the ejector plate to be uneven or deformed;
water hole: used for effective cooling of the mold to keep the mold temperature within a certain range; t
hroat nozzle: installed on the mold transport The water hole is used to connect the cooling water pipe of the beer machine, and is generally made of copper.
(3)Non-standard mold accessories
Non-standard mold accessories refer to the general name of metal accessories used exclusively in the mold industry for stamping molds, plastic molds or FA automation equipment. Mold accessories include: punch needle, punch head, guide post, guide sleeve, ejector pin, cylinder, steel ball sleeve, non-lubrication guide bush, non-lubrication slide plate, guide pin assembly, etc.
(4)Hardware stamping mold accessories
Hardware mold accessories: heavy head, concave mold, discharge insert, slight nail, guide post, guide sleeve, guide pin, spring.
