The utility model discloses bulge tears thickness in limit groove in the middle of the control lower bolster makes it apart from cope match-plate pattern die joint 0.5-0.6mm, makes bridge portion tear limit groove thickness moderate and even, has improved the quality of sealing strip product and the efficiency that the limit was torn to the back way, reduces the cost of labor.
Description
Technical Field
The utility model relates to the technical field of mold, especially, relate to a take bridge sealing strip mould.
Background
With the rapid development of economy, the automobile industry is increasingly prosperous, various automobile products are more and more, the requirements on automobile parts are higher and higher, and the number of the parts is also increased rapidly. For production enterprises, the competitiveness is obviously enhanced, so that the manufacturing cost is reduced, the cost advantage is enlarged, the production efficiency is improved, the product quality is improved, and the method becomes the most important concern of the enterprises. In a factory for molding rubber products, the product is mainly made of rubber, the sealing strip is one of the main products, and compared with other sealing strips with a single structure, the bridged sealing strip has the difficulty and the product quality is relatively difficult to control, so that the product quality and the production efficiency of the bridged sealing strip are improved, and the control of the manufacturing cost is very urgent.
The existing sealing strip mold is of a mold pressing structure and is divided into an upper mold plate and a lower mold plate, the bridge part is matched in a shape shown in figure 1, a tearing groove at the matching part of a bridge part is communicated to the bottom, and inclined planes at four corners are matched and directly milled into vertical planes, so that the tearing groove at the bridge part is too thick and the tearing groove at the bottom is thicker, the flash of a product is too thick, the product is easy to break during edge tearing, and the condition of product cracking is caused; in addition, when the upper die and the lower die are assembled, the rubber fills the whole cavity and the edge tearing groove, when the upper die plate is lifted during demolding, the rubber is adsorbed on the upper die plate, and the flash and the product cannot be completely and completely scraped on the lower die plate, so that the subsequent demolding process is influenced.
SUMMERY OF THE UTILITY MODEL
Based on the technical problem who exists among the background art, the utility model provides a take bridge sealing strip mould.
The utility model provides a take bridge sealing strip mould, including cope match-plate pattern, the lower bolster of arranging from top to bottom, the die cavity that cope match-plate pattern and lower bolster formed is rectangular shape, and the bridge portion of bulge formation product in the middle of the concave part of cope match-plate pattern and the lower bolster has seted up with cope match-plate pattern parting department on the lower bolster and has torn the limit groove, and bulge's in the middle of the lower bolster tear limit groove apart from the cope match-plate pattern die joint 0.5-0.6mm.
Preferably, the edge of the tearing groove of the middle convex part of the lower template is provided with a fillet.
Preferably, the bottom of the middle protruding part of the lower template is circumferentially provided with a belt trough.
Preferably, the tape slot has a semi-circular cross-section.
Preferably, the number of the cavities is more than or equal to 1.
The utility model provides a take bridge sealing strip mould, the thickness of the tear edge groove of the middle bulge of control lower bolster makes it apart from cope match-plate pattern die joint 0.5-0.6mm, makes bridge portion tear edge groove thickness moderate and even; the edge of the tearing groove of the middle protruding part of the lower template is provided with a fillet transition, so that the bridge part tearing groove is prevented from being too deep, the problem of too thick bridge part tearing groove is avoided, the problem of product cracking is solved, and the product quality and the subsequent edge tearing efficiency are greatly improved; the belt material groove is added, when demoulding is carried out, the belt material groove completely carries the flash, the situation that the upper die is pulled by the flash is effectively avoided, products and the flash are completely pulled on the lower die plate, and the demoulding efficiency and the subsequent edge tearing efficiency are greatly improved when workers take off the lower die plate. The utility model discloses an increase in tearing the improvement in limit groove and taking the silo has improved the quality of sealing strip product and the efficiency on limit is torn to the back way, reduces the cost of labor.

Detailed Description
Referring to fig. 2-7, the utility model provides a take bridge sealing strip mould, including cope match-plate pattern 1, the lower bolster 2 of arranging from top to bottom, the die cavity that cope match-plate pattern 1 and lower bolster 2 formed is rectangular shape, and the number of die cavity is more than or equal to 1. The middle groove part of the upper template 1 and the middle bulge part of the lower template 2 form a bridge part of a product, the parting part of the lower template 2 and the upper template 1 is provided with a tearing groove 3, and the distance between the tearing groove 3 of the middle bulge part of the lower template 2 and the parting surface of the upper template 1 is 0.5-0.6mm.
The thickness of the tearing groove of the middle protruding part of the lower template 2 is controlled by the embodiment to be 0.5-0.6mm away from the parting surface of the upper template 1, so that the thickness of the tearing groove 3 of the bridge part is moderate and uniform.
In this embodiment, as shown in fig. 4 and 5, the edge of the tearing groove 3 of the middle protruding portion of the lower template 2 is provided with a rounded corner. Bulge's the limit groove 3 edges of tearing in the middle of the lower bolster is provided with the radius angle transition, has guaranteed that bridge portion tears limit groove 3 and can not be too dark, has avoided bridge portion to tear the problem that limit groove 3 is too thick, has solved the cracked problem of product, very big improvement the quality of product and the back pass efficiency of tearing the limit.
In this embodiment, as shown in fig. 6 and 7, the bottom of the middle protruding portion of the lower die plate 2 is circumferentially provided with a belt material groove 4, and the belt material groove 4 has a semicircular cross section. The belt material groove is added, when demoulding is carried out, the belt material groove 4 completely carries the flash, the condition that the upper template 2 is scraped by the flash is effectively avoided, products and the flash are completely scraped on the lower template 2, and the efficiency of demoulding and subsequent edge tearing are greatly improved as soon as workers take off the lower template.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
