Embodiment 1

[0014] Embodiment one, such as image 3 As shown, the positioning block 321 is a rectangular block whose width matches the specification spacing of the two metal protruding feet 12, and the positioning block 321 is embedded between the two metal protruding feet 12 to avoid the shrinkage of the two metal protruding feet during the cooling process. The distance between the protruding feet changes; the pressure equalizing plate 322 is covered on the top 1 of the vehicle cushion next to the metal protruding feet 12 , and the locking lever 23 is crimped on the pressure equalizing plate 322 . During specific implementation, put the injection-molded uncooled vehicle cushion into the water-cooled shaping tool, place the open inner cavity of the vehicle cushion in a matching manner with the punch, and then insert the positioning block between the two metal protruding feet, and then Set the pressure equalizing plate cover on the top of the vehicle cushion, lock the lever to press and fi...

Embodiment 2

[0015] Embodiment two, such as figure 1 and 2 As shown, the positioning block 321 and the pressure equalizing plate 322 are integrally formed and have two pressing blocks 31 with slots 311. The spacing between the slots 311 matches the spacing between the two metal protruding feet 12; the pressing block 31 is sleeved on the metal protruding pins The foot 12, and the locking lever 23 is crimped on the pressing block 31. During specific implementation, put the injection-molded uncooled vehicle cushion into the water-cooled shaping tool, match the open inner cavity of the vehicle cushion with the punch, and then place the briquetting block on the top of the vehicle cushion. The protruding feet are connected to the grooves of the press block, and the press block is against the top of the vehicle cushion, and the locking lever presses and fixes the press block, and finally the water-cooled shaping tool loaded with the vehicle cushion is placed in the water tank to cool After the ...

Abstract

The invention discloses a water-cooling setting manufacturing tool for an automobile buffering pad. An open inner cavity is formed in the bottom of the automobile buffering pad, and two metal convex pins are integrally embedded into the top of the automobile buffering pad; particularly, the water-cooling setting manufacturing tool comprises an L-shaped base and a fastening unit, and a male die matched with the open inner cavity is arranged on a seat plate of the L-shaped base; the fastening unit comprises a positioning block, a pressure equalization plate and a locking lever pivoted to the top of the side wall of the L-shaped base; the male die is sleeved with the open inner cavity of the automobile buffering pad; the positioning block is connected to the two metal convex pins in an assembled manner; the locking lever presses the automobile buffering pad and is locked. By the adoption of a water-cooling setting mode, a water-cooling setting clamp of the water-cooling setting manufacturing tool speeds up solidification-molding of a molded product, and the production period of the automobile buffering pad is shortened; in a water-cooling setting process, the phenomenon that the inner cavity is contracted or a distance between the metal convex pins is reduced due to cold contraction of the molded product can be effectively avoided; the production efficiency is improved, and the quality of the product is also guaranteed.

Description

technical field [0001] The invention relates to a fixture, in particular to a water-cooled and shaped production auxiliary tool. Background technique [0002] Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. [0003] In the prior art, due to the high structural precision requirements of the automotive cushion pad, it is generally cooled naturally in the mold cavity and then withdrawn to obtain a semi-molded product, which needs to be naturally cooled. However, it takes a long time for natural cooling and solidification, generally more than 24 hours, which has a high requirement for production time, affects production efficiency, and there is a risk of serious product shrinkage, which is not conducive to mass production of molded products.
