Abstract

The invention discloses a mold for producing warm air pipes, comprising an upper mold and a lower mold. The lower mold has a mold cavity, a hole for positioning the mold cavity, grooves on both sides, a blanking piece positioning block, and a positioning groove on the positioning block. The positioning block can rotate freely around the X-axis of the product. The upper mold is provided with a pressing block and a forming convex mold block. The convex mold adopts a half-split structure and is dovetail-connected with a middle oblique block. A spring is installed at the bottom. After the upper and lower molds are completely closed, the forming upper mold is combined with a fixing plate of the middle oblique block. The invention can simply and quickly process the warm air pipe and avoid complicated processes.

Description

Mold for heating pipe production

technical field

The invention relates to a mold for the production of warm air pipes.

Background technique

The shape of the heater pipe is a long sheet, with two ends bent toward the middle to form a three-quarter circle shape. The shape is unique, and the radius of the two circles exceeds the Y axis by 20MM. It cannot be processed with a normal mold structure. The general processing procedures are: blanking punching, preforming, forming, the procedures are complicated and the production efficiency is low.

Contents of the invention

The purpose of the present invention is to provide a mold for the production of warm air pipes, which can produce warm air pipes simply and quickly, avoid complicated procedures and improve production efficiency.

In order to realize above technology, the present invention provides following scheme:

A mold for the production of warm air pipes, including an upper mold and a lower mold, characterized in that: the lower mold has a mold cavity, holes for positioning on the mold cavity, grooves on both sides, and positioning blocks for blanking pieces , there is a positioning groove on the positioning block, the positioning block can rotate freely around the X-axis of the product, the upper mold is provided with a pressing block, and the convex module is formed. The spring is installed, the upper and lower molds are completely closed, and the forming upper mold is combined with the middle inclined block fixing plate.

In the present invention, the upper mold adopts a half-cut structure, which is connected with the middle inclined block by a dovetail, and a spring is installed at the bottom. Squeeze to both sides to process two three-quarter rings. When the upper and lower molds are separated, under the action of the spring, the upper mold springs up and breaks away from the grooves on both sides of the cavity. The slope is calculated based on the product , to ensure that the upper and lower molds are completely closed and then the forming upper mold is combined with the middle inclined block fixing plate.

Detailed ways

A mold for the production of warm air pipes, including an upper mold 1 and a lower mold 2, a cavity 3 on the lower mold, holes for positioning 4 on the cavity, grooves 5 on both sides, and blanking piece positioning blocks 6 , a positioning groove 7 is opened on the positioning block, and the positioning block 6 can freely rotate around the X-axis of the product. The lower mold 2 is provided with a pressing block 8 and a forming convex module 9. The convex mold adopts a half-cut structure, and the middle inclined block adopts a dovetail 10 Connection, spring 11 is installed at the bottom. During the processing, when the upper and lower molds are closed, the two halves of the upper mold are cut and squeezed to both sides through the action of the chute connected by the dovetail 10, and two three-quarter rings are processed. , when the upper and lower molds are separated, under the action of the spring 11, the upper mold bounces upwards and breaks away from the grooves on both sides of the cavity. The slope is calculated based on the product to ensure that the upper and lower molds are completely closed and the upper mold and the middle inclined block are fixed. plate binding.

Claims (1)

1. one kind is used for the mould that the warm braw pipe is produced, and the bag upper die and lower die is characterized in that: on the described counterdie die cavity is arranged, porose location on the die cavity, both sides have groove, blanking sheet locating piece, have locating slot on the locating piece, described locating piece can rotate freely around the product X-axis, and described patrix is established briquetting, the forming convax mould piece, punch takes half-and-half to cut open structure, take dovetail to be connected with middle skewback, the bottom mounting spring, the complete closed aftershaping patrix of mould combines with middle skewback fixed head up and down.
