Abstract
The utility model relates to a sealant cavity adjusting mechanism for an encapsulation injection mold. The sealant cavity adjusting mechanism comprises a movable mold and a mold core on the movable mold, wherein a cavity for accommodating a workpiece to be encapsulated is formed in the mold core; a movable insert is arranged in the cavity; the upper end surface of the movable insert is matched with the workpiece to be encapsulated in appearance; at least one spring hole is formed in the bottom surface of the movable insert; and a strong spring for supporting the movable insert is arranged in each spring hole. As the movable insert is arranged in the cavity of the mold core, and the strong spring is arranged at the bottom of the movable insert, the change of thickness tolerance of an iron product can be absorbed through up-down fluctuation of the movable insert under the action of the strong spring when the iron product is subjected to the thickness tolerance change, thereby facilitating the control on sealants and preventing the sealants from spilling. The sealant cavity adjusting mechanism is convenient and quick to operate, simple and stable in structure and low in cost, is safe and reliable, avoids the product scrap, greatly improves the production efficiency, and ensures the product quality.
Description
Technical field
The utility model relates to a kind of injection mold, what be specifically related to is a kind of for the injection moulding encapsulation die of adjusting sealing die cavity size sealing die cavity governor motion.
Background technology
Injection mold is to use very general a kind of mould in the present industrial processes, mainly by cover half, dynamic model, ejecting mechanism forms, ejecting mechanism is often on dynamic model, during the mould die sinking, dynamic model retreats with workbench, decide dynamic model separately, after dynamic model retreats into certain position, the ejecting mechanism that push pedal on the injection machine promotes mould ejects product, to the recessed product of some sides, often will finish die sinking by pitched roof mechanism is set, to offer corresponding molding character in oblique top, after formed product, oblique top ejects at the promotion decline shaped article of injection machine, finishes die sinking.
Yet injection mold is when encapsulate ironware product, especially the encapsulate of vehicle dormer window spare product, also need to be at the functional area encapsulate on the basis of general stamping parts, but stamping parts raw material thickness generally has ± error of 0.1mm, therefore when encapsulate, it is different that the different-thickness stamping parts is placed on the gap of die die cavity, but during excesssive gap, its sealing is difficult to control, and product rejection rate is high; And because sealing point is many, and existing die cavity Space adjustment complex structure and difficult control, efficient is low, and cost is high, the efficient that impact is produced and the quality of product.
The utility model content
For the deficiency that exists on the prior art, it is a kind of simple in structure, stable that the utility model purpose is to provide, cost is low, be convenient to sealing control and the injection moulding encapsulation die of the glue that prevents from overflowing with sealing die cavity governor motion, solved the product thickness tolerance variation and the problem that is difficult to sealing brought.
To achieve these goals, the utility model is to realize by the following technical solutions:
Injection moulding encapsulation die sealing die cavity governor motion, it comprises dynamic model and the die that is arranged on the dynamic model, it is characterized in that, is provided with the die cavity for the treatment of the encapsulate workpiece for placement at described die, is provided with movable insert in described die cavity; The upper end face of described movable insert with treat that encapsulate workpiece profile is suitable, at least be provided with a spring eye on its lower surface, brute spring for the movable support mold insert is installed in described spring eye, guaranteed that the ironware product is when thickness deviation has change, can sponge by the dipping and heaving of movable insert under the brute spring effect variation of thickness deviation, be convenient to the control of sealing, prevent the generation of excessive glue phenomenon.
Above-mentioned injection moulding encapsulation die sealing die cavity governor motion, wherein, in described die, also be provided with stopper slot, the bottom of described movable insert is provided with the limited block of inserting in the stopper slot, be provided with the free gap between described limited block and the stopper slot, what be convenient to movable insert fluctuates to change sealing die cavity size.
Above-mentioned injection moulding encapsulation die sealing die cavity governor motion, wherein, described free gap is 0.1mm.
The utility model is by arranging movable insert in the die die cavity, and in its bottom brute spring is set, and guaranteed that the ironware product is when thickness deviation has change, can sponge by the dipping and heaving of movable insert under the brute spring effect variation of thickness deviation, be convenient to the control of sealing, prevent the generation of excessive glue phenomenon, it is easy to operate, quick, simple in structure, stable, avoid scrapping of product, safe and reliable, cost is low, improve greatly production efficiency, guaranteed the quality of product.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
