Panel Injection Mold Design

In the design of the panel injection mold, Shanghai Mulan Injection Mold Factory has two positions for the panel in the injection mold, so there are two forms of the injection mold structure scheme. One of them is a simple and easy solution, and the other is a complex and impractical solution. Only through the analysis of the feasibility of the injection mold structure optimization scheme, can we find such a simple and feasible scheme, so as to effectively avoid the failed scheme. Once the injection mold structure scheme is determined,
The specific design or shape of the injection mold is relatively easy.





Shanghai Mulan Injection Mold Factory can design the injection mold according to the conclusion of the demonstration after the shape analysis of the panel and the feasibility analysis and demonstration of the injection mold structure scheme. A total of three horizontal core-pulling mechanisms are used at the left end of the panel injection mold, and the three 'grooves' at the left end of the molded injection molded part adopt a moving mold oblique demoulding mechanism; the dominant 'obstacle body' on the forming panel and the ' Type hole', using the point gate of the latent runner. The location of the point gate is set on the reverse side of the panel, thus ensuring the 'appearance' requirement on the front side of the panel. Because of the point gate of the latent runner, the formwork adopts the form of two templates.


(1) The design of the three-groove core-pulling mechanism at the left end of the panel. The left slider is installed in the groove formed by two left pressure plates, and the left upper core, left middle core and left lower core are fixed in the left slider by cylindrical pins. When the fixed platen is opened, the left curved pin moves The center of the left slider and the upper left core, the middle left core and the lower left core perform core pulling and resetting movements.


(2) The core-pulling design of the two grooves at the right end. The right slider and the right core are installed in the T-shaped groove composed of two right pressing plates. When the fixed platen is opened, the right bending pin moves the right slider and the right core to perform core pulling and reset movement.





(3) The design of front-end groove core pulling. The front slider is installed in the T-shaped slot composed of two front pressure plates. When the fixed mold is opened, the front bending pin moves the front slider to perform core pulling and reset movement.


(4) The design of core-pulling with oblique holes at the end. Diagonal hole forming and core pulling can be formed by a fixed core installed between the inclined push plate and the inclined push backing plate, and the ejection movement of the inclined push plate is pushed by the ejector rod of the injection machine to perform core pulling and reset.


In this way, the forming of the holes and grooves and the core-pulling action can be completed normally. In addition to the above-mentioned design of the panel demoulding and gating system and the design of the de-running condensate, the injection mold can meet the requirements of the appearance of the panel. . Before the design of the panel injection mold, it is necessary to analyze the 'six elements' of the panel shape and the feasibility analysis and demonstration of the injection mold structure optimization plan before the design and modeling of the injection mold structure can be carried out. If a panel sample is provided, be sure to check the structure of the injection molded part, and you can also check the
Check the structure of the injection mold. This is a relatively complete case of feasibility analysis and demonstration of injection mold structure scheme. With this analysis and demonstration method, the blindness of injection mold design can be avoided, and the correctness of injection mold structure design can be independently judged. .





The design of the panel injection mold, Shanghai Mulan Injection Mold Factory injection mold structure molding trace analysis method on the injection sample has the advantage of being intuitive; the disadvantage is poor organization and logic, especially the indirect determination of the injection mold structure plan There are certain concealment, abstraction and hypothetical when using the method. Of course, for the formulation of simple injection mold structure schemes, it can be used; for the formulation of medium-complexity injection mold structure schemes, it can be used reluctantly; for the formulation of complex injection mold structure schemes, there is uncertainty. and limitations. But in any case, a successful injection molded prototype can be regarded as
The reference for the structural design of the injection mold still has great reference value.
