Abstract

The utility model relates to special calipers for a mould, which comprises a left elastic body 8, a right elastic body 9, and a press plate 1. One end of the left elastic body and one end of the right elastic body are respectively and fixedly connected to a left jaw 4 and a right jaw 6. The other end of the left elastic body and the other end of the right elastic body are fixed to each other. A jaw end of the left elastic body and a jaw end of the right elastic body are respectively provided with a pin shaft 7. One end of the pin shaft 7 is hinged with the press plate 1 through the pin shaft 3. The press plate 1 and the lateral surface of the left elastic body 8 form a pivot 2. Jaw end angles 10 of the left jaw 4 and the right jaw are two unequal acute angles. Cutting edges 5 of the left jaw and the right jaw are straight lines. The utility model has the advantages of simple structure, convenient operation, low cost and good quality of incision.

Description

The model special caliper

The utility model relates to school supply and stationery, specifically is the special caliper that a kind of analogue formation is used.

Modelling is the activity that numerous teenagers like.By the making of various models (as model plane etc.), can cultivate the interest of teenager to science and technology, enlarge ken, enrich free life.Present many plastic pattern parts are all used the method injection mo(u)lding of injection moulding, therefore, and cast gate or the rising head used when the mold elements that injects all has many injection mouldings.These cast gates or rising head must be removed from mold elements well, and mold elements could be used.In practical operation, these generally are to cut with a knife to remove attached to cast gate on the mold elements or rising head, and relatively effort, time-consuming, and excision poor quality influences the attractive in appearance and performance of model.Though also sell the model special caliper on the market, the complex structure of clamp costs an arm and a leg, reach 80 yuan as the model special caliper price of a Japanese import, general students in middle and primary schools are difficult to bear.

The purpose of this utility model provides a kind of simple in structure, and is easy to use, can guarantee model workmanship and cheap model special caliper.

The utility model is achieved in that the model special caliper comprises left elastomer, right elastomer, pressing plate and bearing pin.Elastomeric end in a left side and left jaw are connected, and a right elastomeric end and right jaw are connected, and the left and right elastomeric other end is connected mutually.Left and right elastomeric vice jaw part is equipped with a bearing pin, and an end of bearing pin links to each other with pressing plate by another bearing pin.Pressing plate and left elastomeric lateral surface are plane contact, and form the fulcrum that a pressing plate rotates.Vice jaw part angle α, the β at the two ends of left side jaw and right jaw are acute angle, and α＞β.The cutting edge of left side jaw and right jaw is straight line.Two jaws constitute the curved surface of evagination.

During use, position and size according to cast gate cut on the mold elements or rising head, select either large or small vice jaw part angle one end to clamp cut position, depress pressing plate with finger, this moment the fulcrum on the pressing plate promote left elastomer and on left jaw to the right the jaw direction move, with cutting off at cast gate between two jaws or rising head.

Advantage simple structure of the present utility model, easy to operate, cost is low, and kerf quality is good.

Fig. 1 is a front view of the present utility model:

Fig. 2 is the right side view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1.

The utility model is described in further detail below in conjunction with accompanying drawing:

The model special caliper comprises left elastomer 8, right elastomer 9, pressing plate 1.One end and the left jaw 4 of left side elastomer 8 are connected.One end and the right jaw 6 of right elastomer 9 are connected.The other end of left side elastomer 8 and right elastomer 9 is connected mutually.One end of left and right elastomeric band jaw often has bearing pin 7.One end of bearing pin 7 is hinged by bearing pin 3 and pressing plate 1.Pressing plate 1 is plane contact with left elastomer 8, and forms fulcrum 2.Left side jaw 4, right jaw 6 constitute outer convex surface.(α, β) is acute angle and α＞β at the vice jaw part angle 10 at left and right jaw two ends.The cutting edge 5 of left and right jaw is straight line.

During use, the bar that will be wiped out places in the middle of two cutting edges 5, presses dynamic pressure plate 1, and left elastomer 8, left jaw 4 just move to right under the effect of pressing plate fulcrum 2, make two cutting edges, 5 closures, will be wiped out thing and cut.

Claims

1, a kind of model special caliper comprises left elastomer, right elastomer, pressing plate and bearing pin, it is characterized in that elastomeric end in a left side and left jaw are connected, and a right elastomeric end and right jaw are connected, and the left and right elastomeric other end is connected mutually; Left and right elastomeric vice jaw part is equipped with a bearing pin, and an end of bearing pin links to each other with pressing plate by another bearing pin; Pressing plate and left elastomeric lateral surface are plane contact, and form the fulcrum that a pressing plate rotates; Vice jaw part angle α, the β at the two ends of left side jaw and right jaw are acute angle, and α＞β; The cutting edge of left side jaw and right jaw is straight line; Two jaws constitute the curved surface of evagination.
