Description

Technical Field

[0001] The utility model relates to the field of mold structures, in particular to a novel double-strong demolding structure. Background Art

[0002] A mold is a tool that, under the action of external force, makes a blank into a part with a specific shape and size. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. After the mold is cooled after injection molding of the product, the mold needs to be opened and the product is taken out of the mold. Except for soft products such as silicone, the product basically needs to be ejected from the mold by the mold ejection system.

[0003] In the process of demoulding the bottle body or bottle cap, a single strong demoulding is basically used. Since the product itself has an undercut, the single strong demoulding method is easy to cause the product to deform, crack, break, etc. during the demoulding process, affecting the demoulding effect of the product. For this reason, we propose a new double strong demoulding structure. Utility Model Content

[0005] Technical solution: To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new double-strong demolding structure, including a base plate, support plates are fixedly connected to the two sides of the upper outer surface of the base plate, the upper outer surface of the support plate is movably connected to the lower mold frame, a mold is installed in the middle of the upper outer surface of the lower mold frame, the outer wall of the mold is detachably connected to the product, and the outer surfaces on both sides of the base plate are fixedly connected to limited buckle bases.

[0009] Preferably, the inner walls of the No. 6 steel plate, No. 7 steel plate, No. 8 steel plate and No. 9 steel plate are movably connected with guide columns, the upper outer surfaces of the guide columns are fixedly connected with the lower outer surface of the lower mold frame, the outer walls of the guide columns are sleeved with compression springs, and the upper and lower outer surfaces of the compression springs are respectively fixedly connected to the lower outer surface of the lower mold frame and the upper outer surface of the No. 6 steel plate.

[0010] Preferably, a top column is fixedly connected to the outer surface of the upper end of the No. 6 steel plate, and the top column runs through the interior of the mold.

[0011] Beneficial effects: Compared with the prior art, the utility model provides a new double-strong demolding structure, which has the following beneficial effects:

[0012] The novel double-strong demoulding structure has the characteristics of two strong demoulding and ejection, which can meet the integrity of the undercut shape characteristics after the product is formed, break through the bottleneck of the single strong demoulding structure, and meet the product requirements of customers. After the product is injected, it needs to be demoulded. First, the lower mold frame is separated from the upper mold frame, and the injection molding machine ejector is started to make the No. 6 steel plate, No. 7 steel plate, No. 8 steel plate, and No. 9 steel plate move upward at the same time. At this time, the ejector column first ejects the mold upward to create a space between the product and the mold. After ejecting a certain distance, the limit buckle base plays a role in locking the No. 8 steel plate and the No. 9 steel plate. At this time, the No. 6 steel plate and the No. 7 steel plate continue to be ejected upward so that the ejector column ejects the product for a second strong demoulding, and finally the demoulding is completed.
