The barrel mold is one of our most important injection molds. Our barrel molds include thin-walled barrel molds, food barrel molds, barrel molds, cylinder barrel molds, square barrel molds, and rectangular barrel molds. Industrial barrel and bucket molds, Bucket Mould, industrial paint bucket molds, fishing bucket molds, packaging bucket molds, trash bucket molds, cement bucket molds, plastic bucket molds, etc.
First of all, mold design and structure
High-quality mold structure is a prerequisite before qualified mold manufacturing. We attach great importance to the analysis of mold structure, including draft angle, product surface microcosm, gate system design, exhaust design, cooling system design, etc. Prone problems will be solved through trial and error in mold structure design.
2. Two, die steel
In order to improve mold life and product quality, we have improved the hardness of mold steel through heat treatment. In order to prevent mold eccentricity, our commonly used steels are H13 (48-52HRC), 2316 (45-50HRC), etc. We use a single piece of steel to make buckets. The cooling system is very important. We adopt a single-circuit cooling method and set up evenly distributed water channels as much as possible. In order to enhance the cooling effect, BeCu can be inserted into the core and cavity, as shown in the following figure:
Our bucket mold uses air assist device, ejector plate and center ejector for demolding (release in two steps). In order to improve the cooling performance, the center also has a water channel.
All small sliders will be nitrided to increase hardening.
Maintaining mold maintenance is very important. We should check to make sure that the water channel and air circuit are unlocked. Lubricate the muffler and clean the scraper and center ejector regularly.
3. Third, mold cooling system
The design of the cooling system is a relatively cumbersome task, that is, the uniformity and cooling effect of the cooling must be considered, and the entire mold structure must also be affected. The exact position and size of the cooling system must be determined; and the cooling of key locations, such as Movable plates or inserts, side sliders and side cores; standard cooling element design and selection of standard cooling components. Micon Plastic Mould analyzes all a series of factors when starting the mould design. Each part of the mold has circulating water flow, which reduces cooling time, improves production efficiency, and greatly reduces product costs.
