Re-use of cold and hot frame standard parts model

In the process of one parting, the movable core 17 is pulled by the chute in the fixed mold plate 18, and the movable core is further guided under the guiding hole of the fixed mold insert 23 to complete the pumping of the movable core. Core action. When the mold is opened 6mm, the movable core is cored and put into a safe position. At this time, the fixed die plate 24 starts to be separated from the movable die by the action of the stopper screw 13, and the fixed die plate 24 is separated from the movable die plate 25 to complete the secondary splitting.

Subsequently, the plastic part is pushed out by the push rod. When the mold is closed, the movable core 17 is pushed by the backing plate 16, while the movable core is again reset under the guide of the fitting hole in the fixed mold insert 23. After the mold is closed, the entire cycle of plastic injection is completed. It is more common to design plastic parts with inclined holes, which also brings certain difficulties to the mold design.

The difference in the arrangement of the inclined holes in the plastic parts and the difference in the relevant parameters require a corresponding change in the mold structure. After the specific analysis of the plastic part, the mold structure that relies on the chute sliding is adopted. The practical application proves that the mold test mold is injection-molded once, the quality of the plastic parts is good, and the mold structure is simple and convenient to use. For similar parts, the mold structure has good practicality.

The collection and storage of scrap molds are first selected from the scrap molds, and then discarded by the professional technicians. Then the labels are sorted by professional technicians. The cold and hot emblems are used to classify the special warehouses. The storage personnel are classified according to the material and geometric size of the molds. Place it, and register it for the people's library, so that it can be used for restructuring.

The method of recycling the mold for the hexagonal head bolt is mainly based on the principle of "small to large". For example, if the M10 hex head bolt cold shrinkage die and die are scrapped due to wear, the reduced diameter die and the die used in the M12 hex head bolt can be modified. When machining, the mold can be trimmed only for the mold without damage and wear on the outer circle, and the outer diameter can be selected as the machining reference. For the mold whose outer circle has been scratched, the inner hole can be ground to the size before machining, and then the outer circle can be grounded with the inner hole as the reference.

Machining process of mold recycling (1) Firstly, the professional technicians design the required mold according to the product specifications to be processed, and then prepare the repair processing according to the size and material number of the mold in the scrap mold stacking warehouse.

(2) The scrap mold is repaired and processed by a special mold processing workshop and specialized workers. (3) Inspection and acceptance of the repaired mold by special quality inspectors.

(4) Repair the processed mold to send and repair the mold finished product warehouse for storage and standby. Standard fasteners are cold.

The recycling of the heat emblem mold seems to be an insignificant task, but through the above work, it can save the company's capital and reduce the production cost of the product.
