Technical Field

The invention relates to the field of design of lampshade molds, in particular to an auxiliary mold opening structure of a double-color headlamp lampshade mold.

Background

Double-colored headlight cover of car light factory adopts double-colored injection molding machine to mould plastics at present, and the main defect of this injection molding machine is motor drive for the intermediate lamella that is used for fixed movable mould, and there is the problem that the intermediate lamella can not be opened after the product pressurize when moulding plastics, and the division of movable mould and cover half is comparatively hard promptly, can't guarantee the stability of production.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides an auxiliary die opening structure of a double-color headlamp lampshade die, so that the fixed die and the movable die can be separated in a labor-saving manner.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides an supplementary die sinking structure of double-colored headlamp lamp shade mould, includes the cover half and the movable mould of mutually supporting, pushes away the unit including supplementary, and supplementary pushing away the unit includes fixed hydro-cylinder on the operation side of cover half and the fixed dog on the operation side of movable mould, and the rod end of the ejector pin in the hydro-cylinder is arranged to the dog, and can promote the dog when the hydro-cylinder drives the ejector pin and stretches out.

The auxiliary pushing-away units are two and are symmetrically arranged on the operation side and the non-operation side of the fixed die.

The number of the auxiliary pushing-away units is four, the number of the operating sides of the fixed mold is two, the number of the non-operating sides of the fixed mold is two, the two auxiliary pushing-away units on the operating side of the fixed mold are arranged in parallel at intervals, and the two auxiliary pushing-away units on the non-operating side of the fixed mold are arranged in parallel at intervals.

The oil storage barrels in all the oil cylinders are respectively communicated with the oil outlets of the oil collection block through oil pipes, and the oil inlets of the oil collection block are connected with the oil nozzles of the injection molding machine through pipelines.

Has the advantages that: when the die sinking is needed, the oil cylinder is started, the oil cylinder drives the ejector rod to be ejected out, the ejector rod further pushes the check block, and the check block is fixed on the side face of the movable die, so that the movable die can be driven to move by the movement of the check block, the die sinking can be assisted, the fixed die and the movable die can be separated in a labor-saving manner, and the production efficiency is improved.

Detailed Description

The invention is further described below with reference to fig. 1.

The utility model provides an auxiliary die sinking structure of double-colored headlamp lamp shade mould, includes the cover half 10 and the movable mould 20 of mutually supporting, including the supplementary unit of pushing away, the supplementary unit of pushing away includes the fixed hydro-cylinder 30 on the operation side of cover half 10 and the dog 40 of fixing on the operation side of movable mould 20, and the dog 40 is arranged at the rod end of the ejector pin 31 in the hydro-cylinder 30, and can push the dog 40 when hydro-cylinder 30 drives ejector pin 31 and stretches out. When the mold is required to be opened, the oil cylinder 30 is started, the oil cylinder 30 drives the ejector rod 31 to eject, the ejector rod 31 further pushes the check block 40, and the check block 40 is fixed on the side surface of the movable mold 20, so that the movable mold 20 can be driven to move by the movement of the check block 40, the mold opening can be assisted, the fixed mold and the movable mold can be separated in a labor-saving manner, and the production efficiency is improved.

Further, the auxiliary pushing-away units are two and symmetrically arranged on the operation side and the non-operation side of the fixed die 10. The auxiliary pushing units are symmetrically distributed, so that the auxiliary die opening force is symmetrically distributed, and the die opening is more labor-saving.

Preferably, the number of the auxiliary pushing-away units is four, the number of the operation sides of the fixed mold 10 is two, the number of the non-operation sides of the fixed mold 10 is two, the two auxiliary pushing-away units on the operation side of the fixed mold 10 are arranged in parallel at intervals, and the two auxiliary pushing-away units on the non-operation side of the fixed mold 10 are arranged in parallel at intervals. So that the mold opening is more labor-saving.

Further, the oil storage barrels in all the oil cylinders 30 are communicated with the oil outlets of the oil collection block 50 through oil pipes respectively, the oil inlets of the oil collection block 50 are connected with oil nozzles of an injection molding machine through pipelines, the injection molding machine supplies oil to all the oil cylinders 30 simultaneously, the oil cylinders 30 are guaranteed to act simultaneously, and force for assisting mold opening is applied simultaneously.

It should be understood that the above-described specific embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Obvious variations or modifications which are within the spirit of the invention are possible within the scope of the invention.
