Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0013] Such as Figure 1~4 As shown: four male molds 4 are vertically fixed on the back of the upper formwork 1 through the fixing plate 10, and there is an inverted convex structure connected to it by a plurality of unloading bolts (not shown in the figure) below the fixing plate 10. Unloading block 6, between the unloading block and the fixed plate 10, there are first springs 9 respectively sleeved on each unloading bolt, and the lower part of the unloading block 6 is provided with a concave mold on the lower template 7; Through grooves 5 matching the male mold 4 are distributed on the discharge block.

[0014] In order to compress the water chamber body 12 conveniently, and also in order to facilitate unloading, the female mold is composed of an L-shaped fixed block 8 fixed on the lower template 7, an inverted L-shaped slide block 3 arranged on t...

Abstract

The invention discloses a punching pressing trap die and belongs to stamping dies. According to the punching pressing trap die, a plurality of welding-locating groove dies can be machined on the inner wall of a water chamber body by one-time stamping. The punching pressing trap die comprises an upper die plate, a lower die plate, male dies, a female die and a discharging device. The male dies (4) are fixed on the back face of the upper die plate through a fixing plate (10). A discharging block (6) connected with the fixing plate (10) through a discharging bolt is arranged below the fixing plate (10). A first spring (9) is arranged between the discharging block and the fixing plate (10). A concave-shaped female die arranged on the lower die plate (7) is arranged below the discharging block (6). The discharging block (6) is of a reversed-convex-shaped structure. Through grooves (5) matched with the male dies (4) are distributed in the discharging block. The punching pressing trap die has the advantage of being simple in structure, convenient to use, high in efficiency and the like, and the punching pressing trap die is a stamping die which is used for machining radiator water chamber inner wall welding locating grooves.

Description

technical field [0001] The invention relates to a grooving die, in particular to a punching and pressing die which integrates grooving and stamping grooves. Background technique [0002] The water chamber is an important part of the radiator. It is usually composed of a water chamber body and a partition welded in the water chamber body to divide it into multiple cavities; A concave welding positioning groove is provided on the inner wall. At present, milling is generally used for processing, which is low in efficiency and high in cost, and cannot meet the requirements of large-scale production; there is an urgent need for a mold that can process multiple welding positioning grooves on the inner wall of the water chamber body in one stamping to meet large-scale production. production needs. Contents of the invention [0003] In order to overcome the defects in the prior art, the present invention aims to provide a punching and pressing die that can process multiple weldi...
