TW202401B - A venting valve device for diecasting moulds - Google Patents

Abstract

A pressure casting die consists of two die halves that can move along the parting surface, and a vent valve composed of two separable parts each disposed on the die half and moving along with the die half to define a ventilation opening connected to the cavity and extending along the parting surface. When the die halves are assembled, a device is provided to exert a spring force to keep these two parts close to each other, as a consequence of which the action forces existing between the two parts and existing between the die halves will not be mutually affected.

Description

Printed by R Industry and Consumer Cooperative, Central Bureau of Standards, Ministry of Economic Affairs ^ 02401 Λβ Β6 V. Description of the invention (1) 1 The present invention has a kind of pressure-binding chess piece. The die-casting module must be able to ventilate, and there must be a venting vent at the venting end. The vent valve is not installed in the half-bound module, or it is screwed on the cast piece to make it flush with the end face of the yoke module. The end face of the vent valve must be exactly aligned with the parting surface of the 5 cast module; in this way, after closing the checker piece, the end face of the vent valve can completely accept the mating surface of the other half of the thin module to prevent the installation work After the melted Jin Yi squirted out. As long as this requirement can be achieved, sickle operations can always maintain zero failures. However, in many manufacturing processes, the difference is in large thin parts. 10 The temperature difference between the thin modules often causes one of the filling and semi-cast modules to deform, and then it is no longer possible to guarantee the two- and half-cast modules. Complete seal. This will cause molten metal to be ejected from the end surface of the vent thief and the mating surface of the suspect module, resulting in damage to the vent valve; or, because the metal adheres to the end surface where the valve port encounters, it often obstructs the operation. 15 The purpose of the present invention is to alleviate this shortcoming, and to improve the closure between the end face of the vent valve and the K-joint surface of the other half of the casting module. Even if the yoke module is deformed, the closure can be improved. The bundling force binding module of the present invention includes: two half-yong-yong modules, the two europium-half-binding modules can be matched along the parting plane of the pan, and also defines a mold cavity; and a > On the separable parts of the semi-half module. The two separable parts can be matched along the parting surface, thereby defining a vent, the vent is in communication with the mold cavity, and extends along the parting surface, where There is a device that can deflect the separable parts of the vent valve so that the separable modules can bring the separable parts close to each other when they are combined; so (please read first ...) ; 1. * Lu Xiang Zai to write this page)-丨 installed. .ΪΤ. —Line.

Description of invention ( 2) 1 The force between the two tilting separable parts and the force between the two half-cast pieces will not affect each other. The device of the present invention has a compensator, which can prevent adverse factors such as deformation due to temperature change of the thin force module from being added to the vent valve of the stress casting block 5. This device can reliably prevent molten gold from spraying near the vent valve, and greatly reduce accidents while improving production efficiency. The present invention will be exemplified below with reference to the coil type.

Description of invention (3) L 15 is installed on the fixed semi-cast module 3, and the matching member 15 is located on the opposite side of the part 6, the screw 16 _ It is guided into the slot 15b by the spring washer 17. The mating member 15 is pushed to the right by the spring system with the thin piece 10, the piston Π and the spring 12, and as a result the surface of the mating member 15 ( (It) cooperates with the end surface 6a of the vent valve part 6) to cross the end surface 6a of the semi-cast module 4 (which is on the parting surface of the combination block) by a distance 13. For convenience, the distance 13 is about 0.1cb. When the casting module is closed (as shown in the third circle), the rearward movement of the mating member 15 causes the spring 12 to be compressed to generate an elastic force. As a result, the mating surface 15a of the mating member 15 and the end surface 6a of the vent valve part 6 are straight 10 Will be tightly closed, even if the semi-thin module 3 or 4 is deformed by 0.03cb due to temperature or other reasons, the two-tilt semi-thin module 3 or 4 will also be tightly closed.
