Description

Prevent that mould mechanism of thimble seal problem from appearing on product surface

Technical Field

The utility model relates to an injection mold technical field specifically is a prevent that thimble seal problem's mould mechanism from appearing in product surface.

Background

With the development of times, the living standard of people is continuously improved, and the demand of plastic products is more and more large. The production of plastic products is realized by an injection mold, and the mold has the advantages of short production time and high speed, thereby becoming an important way for obtaining various plastic products. The ejection system of the mold is an important component of the mold. The common ejection modes comprise ejection of an ejection block, ejection of an inclined ejector and ejection of an ejector pin. When the product is small and the space is insufficient, the thimble is the only means, and after the product is ejected, the position corresponding to the thimble will have impressions of white top and uneven. These marks affect the appearance of the product and may not meet the quality requirements of the product.

In the prior art, the thimble is the most widely applied thimble, but when some products with higher surface requirements are encountered, the thimble impression is the problem which is difficult to solve. When the product is injected, the pressure of the injection molding machine is higher, so that the thimble has a small amount of relative movement, and then the impression can appear. To address these issues, a top block may be used for ejection. However, the space required by the top block is large, the processing is complicated, a large amount of cost is wasted, and the replacement is inconvenient.

Preferably, the lower end of the product is provided with two groups of thimbles.

Preferably, two sides of the guide block are respectively connected with the lower end of the rear template through two hexagon socket head cap screws.

Preferably, the gasket is connected with the tail end of the thimble through a hexagon socket head cap screw.

Preferably, the thimble bottom plate and the thimble panel are both provided with the thimble moving hole.

Advantageous effects

The utility model discloses a prevent that mould mechanism of thimble seal problem from appearing on product surface, mould head are equipped with the inclination, fix a position more accurately firm like this, and the bottom is equipped with 1.5-3 mm's bearing surface, can bear bigger injection pressure like this, can make product shaping effect better. The back has single inclination and is surrounded all around, so that the processing is convenient and the efficiency is high. The material selects the common thimble in the market, and the price is cheap, and the purchase is convenient, and it is also more convenient to change.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Examples

As shown in fig. 1-3, a mold mechanism for preventing a product surface from being printed with an ejector pin comprises a base plate 1, an ejector pin base plate 2 and an ejector pin panel 3 are arranged at the middle position of the upper end of the base plate 1, square irons 4 are symmetrically arranged on two sides of the ejector pin base plate 2 and the ejector pin panel 3, a rear mold plate 5 is arranged on the square irons 4, four groups of guide posts 8 are symmetrically arranged at two sides of the upper end of the rear mold plate 5 respectively, a rear mold core 6 is arranged in the middle of the upper end of the rear mold plate 5, a product 7 is arranged in the middle of the rear mold core 6, an ejector pin 9 is arranged at the lower end of the product 7, a guide block 10 is arranged at the lower end of the ejector pin 9, the ejector pin 9 penetrates through the guide block 10 to be connected with.

Preferably, two groups of thimbles 9 are arranged at the lower end of the product 7.

Preferably, two sides of the guide block 10 are respectively connected with the lower end of the rear template 5 through two hexagon socket head cap screws.

Preferably, the gasket 11 is connected with the tail end of the thimble 9 through a hexagon socket head cap screw.

Preferably, the thimble base plate 2 and the thimble panel 3 are both provided with a thimble 9 moving hole.

The ejector pin of the mould ejects a product along with the movement of the ejector pin plate, the ejector pin bottom plate pushes the gasket to enable the ejector pin to move upwards to eject the product, when the ejector pin panel returns, the gasket is pressed downwards to enable the ejector pin to return, and the back of the ejector pin is used for accurately returning to a corresponding position.
