Technical Field
The utility model relates to the field of injection molds, in particular to a demolding mechanism capable of smoothly demolding.
Background
The injection molding process is a common production process, and a molding machine is used for injecting materials in a molten state into a cavity of a mold, and the materials are cooled to form a product which is in accordance with the shape of the cavity. When the injection mold is used for preparing a product, as the insert is gradually pulled out from the cavity, vacuum is formed in the cavity, so that the movement of the insert can be prevented, and further, the defects such as mold carrying, local deformation and fracture, product movement during pulling out and the like can occur. In order to solve the above problems, the conventional mold is provided with an air inlet passage communicated with the inside of the insert, but for some structures with smaller partial areas or the need of adding cooling water passages, the air inlet passage structure cannot be provided due to space limitation, so that the problems existing in the vacuum demolding cannot be solved. There is thus a need for a method or apparatus that solves the above-mentioned problems.
Disclosure of Invention
The utility model aims to solve the technical problems, and provides the demoulding mechanism which is simple in structure, ingenious in design and reasonable in layout, and can still ensure smooth demoulding action under the condition that an air inlet passage cannot be arranged.
The technical scheme of the utility model is as follows: the utility model provides a demoulding mechanism that can smooth and easy drawing of patterns which characterized in that: the mechanism comprises an oil cylinder 1 arranged in an injection mold, the working end of the oil cylinder 1 is connected with a slide block seat 2, the end face of the slide block seat 2 far away from the oil cylinder 1 is also connected with a vacuum slide block 3, a cooling water cavity 4 and a gas storage cavity 5 are arranged in the vacuum slide block 3, an opening of the cooling water cavity 4 is connected with a cooling water pipeline 6, the tail end of the cooling water pipeline 6 is connected with a water pump in a cooling water circulation system through a hose, the opening of the gas storage cavity 5 is positioned on the end face of one end of the vacuum slide block 3 positioned in a cavity, a gas plug 7 is arranged at the opening of the gas storage cavity 5,
the air blocking head 7 is cylindrical in whole, the outer diameter of the air blocking head is matched with the inner diameter of the air storage cavity 5, and four exhaust channels 8 which are uniformly distributed in the circumferential direction and distributed along the axial direction of the air blocking head 7 are formed in the side wall of the air blocking head 7.
Compared with the prior art, the utility model has the following advantages:
the utility model provides a demoulding mechanism that can smooth and easy drawing of patterns of structural style, its simple structure, design benefit, it is rationally distributed, it is to the problem that traditional demoulding mechanism exists when unable installation gas circuit of admitting air, design a special structure, it has seted up a cavity in the vacuum slider, and set up the gas end cap of a special structure in the opening part of cavity, this gas end cap can form the vacuum state in the die cavity after, let the air in the cavity slowly get into in the die cavity, in order to reduce the vacuum degree in the die cavity, thereby guarantee that the action of loosing core can go on smoothly, and avoid taking the mould, the emergence of bad circumstances such as product drunkenness when local deformation breaks or take out. The demoulding mechanism has the advantages of simple manufacturing process and low manufacturing cost, is particularly suitable for popularization and application in the field, and has very broad market prospect.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present utility model.
Fig. 2 is a schematic structural view of a gas plug portion in an embodiment of the present utility model.
Detailed Description
Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. As shown in fig. 1 and 2: the demoulding mechanism capable of smoothly demoulding comprises an oil cylinder 1 arranged in an injection mould, wherein the working end of the oil cylinder 1 is connected with a slide block seat 2, the end face of the slide block seat 2 far away from the oil cylinder 1 is also connected with a vacuum slide block 3, a cooling water cavity 4 and a gas storage cavity 5 are arranged in the vacuum slide block 3, an opening of the cooling water cavity 4 is connected with a cooling water pipeline 6, the tail end of the cooling water pipeline 6 is connected with a water pump in a cooling water circulating system through a hose, the opening of the gas storage cavity 5 is positioned on the end face of one end of the vacuum slide block 3 positioned in a cavity, a gas plug 7 is arranged at the opening of the gas storage cavity 5,
the air blocking head 7 is cylindrical in whole, the outer diameter of the air blocking head is matched with the inner diameter of the air storage cavity 5, and four exhaust channels 8 which are uniformly distributed in the circumferential direction and distributed along the axial direction of the air blocking head 7 are formed in the side wall of the air blocking head 7.
The working process of the demoulding mechanism capable of smoothly demoulding in the embodiment of the utility model is as follows: when the mold is closed, the working end of the oil cylinder 1 drives the slide block seat 2 to move towards the direction of the mold cavity, the vacuum slide block 3 connected with the end part of the slide block seat 2 enters the mold cavity and forms a part of the mold cavity to participate in molding; injecting a molten material into the cavity by the forming machine, and forming a shape matched with the cavity, namely a workpiece after the material is cooled;
when the mold is opened, the oil cylinder 1 drives the slide block seat 2 to pull the vacuum slide block 3 to move towards the direction away from the mold cavity, but the vacuum state in the mold cavity is adopted at the moment, the adsorption force generated by vacuum can block the movement, at the moment, the air stored in the air storage cavity 5 can enter the mold cavity through the exhaust channel 8 on the side wall of the air blocking head 7, the vacuum degree in the mold cavity is reduced, so that the vacuum slide block 3 can be ensured to slide out of the mold cavity smoothly, and meanwhile, the defects such as product movement and the like when the mold is carried, the partial deformation is broken or the product is extracted can be avoided.
It should be noted that, in the injection molding process, the molten plastic-resin material does not enter the air storage cavity 5 through the air exhaust channel 8, because the flow of the plastic-resin material has a certain requirement for a gap, and the molten plastic-resin material cannot flow in a smaller gap, so that in the actual design, the caliber of the air exhaust channel 8 is only selected according to the flowability parameter of the plastic-resin material which is currently required to be used, and the normal operation of the device can be ensured.
