Pipe orifice whole-orifice mold of automobile heat exchange system and mold release method thereof

Abstract

The invention belongs to the technical field of automobiles and specifically relates to a pipe orifice whole-orifice mold of an automobile heat exchange system. The pipe orifice whole-orifice mold ofthe automobile heat exchange system comprises a pipe core embedded part, a small slide seat, a pipe orifice embedded part, a big slide seat, two press strips and multiple limiting blocks; the pipe core embedded part is connected with the small slide seat; the pipe orifice embedded part is connected with the big slide seat; a first guide groove is formed in the middle part of the big slide seat; the small slide seat is in sliding connection with the first guide groove; a small slide guide column on the small slide seat is matched with a second guide groove in the small slide seat; the two pressstrips are symmetrically arranged on the two sides of the big slide seat; the two press strips are in sliding connection with clamping projections on the two sides of the big slide seat; the pipe core embedded part is accommodated in the pipe orifice embedded part; a big slide guide column and a clearance groove are arranged on the big slide seat. The pipe orifice whole-orifice mold of the automobile heat exchange system has the advantages that the service life is long, the pipe orifice has no miscellaneous wire, and moreover, the strength is good, the pipe orifice is uneasy to wear, the maintenance cost is low, a water path can be additionally arranged on the circumferential ring of the pipe orifice, and the stability in the injection molding process is good. In addition, the invention further provides a mold release method to enhance the working stability and efficiency of the pipe orifice whole-orifice mold of the automobile heat exchange system.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a mold for integral opening of a nozzle of an automobile heat exchange system and a demoulding method thereof. Background technique [0002] In electric vehicles such as electric vehicles and hybrid vehicles, a power converter (inverter) converts DC power supplied from a high-voltage storage battery (such as a lithium-ion battery) into AC power, and uses this AC power to drive a motor (such as a three AC motor) rotates, thereby generating the driving force of the vehicle. In addition, when the vehicle is decelerating, regenerative energy obtained by regenerative power generation of the electric motor is stored in the battery, thereby reducing waste of energy and realizing efficient energy utilization. In these cars, the car heat exchange system is used for heat dissipation, and the structure of the car heat exchange system has an important influence on the heat d...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in the mold for producing the nozzle of the automobile heat exchange system, the nozzle is half-opened through the front and rear insert molds, and the tube core is ejected in rows. This type of mold has several disadvantages: 1. Since the nozzle is opposite Half-open, resulting in a pinch in the middle of the nozzle, which is difficult to trim, and the pinch here affects the service life of the product; 2. Since the front and rear inserts are used to open the mold, it is difficult to increase water cooling, resulting in unstable deformation during the injection molding process ;3. Due to the strong corrosiveness of the material, the production time is long, and it is easy to produce batch fronts at the position of miscellaneous wires, resulting in increased production and maintenance costs.
