Description
Technical Field
The utility model relates to an injection mold especially relates to an antiseized cover half mould structure.
Background
The plastic injection mold is a tool for producing plastic products and has wide application. In the injection molding of plastic products, as shown in fig. 1, since the mold positions of some plastic products 100 are basically the same before moving, the mold is easy to be stuck, and the plastic products cannot be released from the mold cavity after molding.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an antiseized cover half mould structure that can effectively prevent plastic products sticking mould.
In order to achieve the above object, the technical solution of the present invention is:
the utility model relates to an anti-sticking fixed die structure, which comprises a fixed die plate, a movable die plate, a fixed die insert, a fixed die pressing plate, a fixed die insert pin with teeth, a nylon pull buckle, a movable die insert pin, a movable die insert and a spring; the fixed die plate and the movable die plate are overlapped together; the upper end of the fixed die insert is fixed on the fixed die pressing plate, the lower end of the fixed die insert extends into the cavity, the fixed die pressing plate and the fixed die insert fixed on the fixed die pressing plate are movably sleeved in the fixed die plate, the upper end of the fixed die insert with the die insert is fixed on the fixed die pressing plate, the upper end of the nylon pull buckle is locked at the lower end of the fixed die insert, and the lower end of the nylon pull buckle is fixed on the movable die plate; the movable mold insert is movably sleeved in the movable mold plate, the upper end of the movable mold insert extends into the cavity, and the spring is arranged between the movable mold insert and the movable mold plate.
The fixed die pressing plate, the fixed die insert and the movable die insert are all provided with two parts; the two fixed die pressing plates are respectively fixed on and bridged on the top surfaces of the two fixed die inserts.
The utility model also comprises a top rod and a top plate; the upper part of the ejector rod is movably arranged in the movable template in a penetrating way, and the lower end of the ejector rod is fixed on the top plate.
The movable mold insert and the movable mold plate are both provided with spring grooves, the springs are sleeved in the spring grooves, and two ends of each spring are respectively abutted against the movable mold insert and the movable mold plate.
After the scheme is adopted, because the utility model discloses a fixed die plate, movable mould board, cover half mold insert, cover half clamp plate, cover half area tooth inlay needle, nylon draw the knot, movable mould mold insert, spring, at the die sinking in-process, the cover half mold insert is because the pulling force that nylon drawn the knot can break away from the cover half along with the product together, and it is spacing because of cover half clamp plate stroke has to be done, so the cover half mold insert can throw off the product after breaking away from one section distance, can guarantee like this that the product can not glue the cover half when the die sinking.
The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description
As shown in fig. 2-7, the utility model relates to an antiseized cover half mould structure, including fixed die plate 1, movable mould board 2, cover half mold insert 3, cover half clamp plate 4, cover half area tooth inlay pin 5, nylon draw and detain 6, movable mould mold insert 7, spring 8, ejector pin 9 and roof 10.
The fixed template 2 and the movable template 3 are overlapped together; the upper end of the fixed die insert 3 is fixed on the fixed die pressing plate 4, the lower end of the fixed die insert 3 extends into the cavity, the fixed die pressing plate and the fixed die insert 3 fixed on the fixed die pressing plate are movably sleeved in the fixed die plate 1, the upper end of the fixed die insert with the die insert 5 is fixed on the fixed die pressing plate 4, the upper end of the nylon pull buckle 6 is locked at the lower end of the fixed die insert 5, and the lower end of the nylon pull buckle 6 is fixed on the movable die plate 2; the movable mold insert 7 is movably sleeved in the movable mold plate 2, and the upper end of the movable mold insert 7 extends into the mold cavity; the movable mold insert 7 and the movable mold plate 2 are both provided with spring grooves 71 and 21, the spring 8 is sleeved in the spring grooves 71 and 21, and two ends of the spring 8 respectively abut against the movable mold insert 7 and the movable mold plate 2.
In this embodiment, the fixed mold pressing plate 4, the fixed mold insert 3 and the movable mold insert 7 are provided with two parts; the two fixed die pressing plates 4 are respectively fixed and bridged on the top surfaces of the two fixed die inserts 3.
The upper part of the ejector rod 9 is movably arranged in the movable template 2 in a penetrating way, and the lower end of the ejector rod 9 is fixed on the top plate 10.
The utility model discloses a theory of operation:
in the process of die sinking, the fixed die insert 3 can be separated from the fixed die along with the product along with the pulling force of the nylon pull buckle 6, the stroke of the fixed die pressing plate 4 is limited, so the fixed die insert 3 can be separated from the product 100 after being separated from a certain distance, the fixed die can not be stuck when the product 100 is die sinking, the movable die insert 7 can also move forwards for a certain distance along with the popping of the spring 9 (the movable die pressing plate 4 also has the stroke limitation), the ejection is carried out after the die sinking is finished, and the product 100 automatically drops.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
