Abstract
The invention discloses a sliding thimble mechanism for preventing products from being strained. The sliding thimble mechanism comprises a fixed template and a movable template, wherein a die cavity is formed between the fixed template and the movable template; and a die core is arranged in the die cavity. The sliding thimble mechanism is characterized in that a sliding thimble for preventing the products from being strained by sliding motion is arranged on the sliding position of the die core. The invention aims at overcoming the defects in the prior art and provides the sliding thimble mechanism for preventing the products form being strained. The sliding thimble mechanism has a simple structure and can be used for preventing the products from moving towards the side along the sliding, thereby preventing the products from being strained, broken off and the like by the sliding.
Description
Technical field
The present invention relates to a kind of row position ejector pin mechanism that prevents that product from pulling.
Background technology
Existing plastic mould; In the process of product stripping; When some product is done the motion of row position; Move because thereby product has can product also can and then go when move in the next door with the bigger position of being expert at of package power of row position very much, thereby cause that product pulls the generation of situation such as fracture to the next door.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome weak point of the prior art, can prevent product and then the row position to the next door motion, thereby prevent that product from being pulled by the row position, the generation of the fracture imagination of etc.ing prevent the ejector pin mechanism of going that product pulls.
In order to achieve the above object, the present invention adopts following scheme:
A kind of row position ejector pin mechanism that prevents that product from pulling; Comprise solid plate and moving platen; Form a die cavity between described solid plate and the moving platen; In described die cavity, be provided with core, it is characterized in that: on the row position of said core, be provided with the row position thimble that position motion the causing product that can prevent to be expert at is pulled.
An aforesaid a kind of row position ejector pin mechanism that prevents that product from pulling is characterized in that described core comprises to be arranged on the front mould on the described solid plate and to be arranged on the back mould on the described moving platen.
Aforesaid a kind of plastic mould inclined plate is characterized in that on described solid plate, being provided with fixed clamping plate.
Aforesaid a kind of plastic mould inclined plate is characterized in that on thimble one end of described row position, being provided with arc surface.
In sum, the present invention with respect to its beneficial effect of prior art is:
The present invention is simple in structure, can prevent product and then the row position to the next door motion, thereby prevent that product from being pulled by the row position, fracture waits the generation of the imagination.
Description of drawings
Sketch map when Fig. 1 is a matched moulds of the present invention;
Fig. 2 is the enlarged drawing at A place among Fig. 1;
The sketch map of Fig. 3 during for die sinking of the present invention;
Fig. 4 is the enlarged drawing at B place among Fig. 3;
Fig. 5 is the sketch map of prior art plastic mould.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the present invention is further described:
A kind of row position ejector pin mechanism that prevents that product from pulling shown in Fig. 1 to 4; Comprise solid plate 1 and moving platen 2; Form a die cavity 3 between described solid plate 1 and the moving platen 2; In described die cavity 3, be provided with core 4, on the row position 5 of said core 4, be provided with the row position thimble 6 that position 5 motions the causing product that can prevent to be expert at is pulled.
On described solid plate 1, be provided with fixed clamping plate 7 among the present invention.
Being illustrated in figure 5 as existing plastic mould generally is not to be with push pin device when making the row position; Be expert in the making of position because product is deep with the contact-making surface of row position; Thereby because the package power of product is big, product is very likely followed the motion toward the next door of row position, thereby causes pulling of product in motion in the row position; The fracture of row bit position is etc. the generation of bad phenomenon.
As illustrated in fig. 1 and 2 for the structure of the capable position of plastic mould of the present invention thimble.Row position thimble is just at the glue plane in the mould matched moulds.
State when Fig. 3 and 4 is moulds open; Move to the next door in mould row position in the motion process from Fig. 1 to Fig. 3; But row position thimble 6 is gone straight up to overleaf and is withstood product under the effect of position and it can and then go move to the next door; Thereby reach its desired effect, such way can make the product of this type can not cause product to be pulled because of the reason with the motion of row position, bad phenomenons such as fracture.
Claims (4)
1. row position ejector pin mechanism that prevents that product from pulling; Comprise solid plate (1) and moving platen (2); Form a die cavity (3) between described solid plate (1) and the moving platen (2); In described die cavity (3), be provided with core (4), it is characterized in that: on the row position (5) of said core (4), be provided with the row position thimble (6) that position (5) motion the causing product that can prevent to be expert at is pulled.
