The utility model discloses an go up the mould and set up to the double-sided type, greatly reduced the volume and the weight of mould, it is more nimble convenient to carry out the change operation of moulded die with rotatory mode simultaneously.
Description
Technical Field
The utility model belongs to the technical field of polyurethane goods technique and specifically relates to a rotatable polyurethane dual density shoe mold.
Background
Polyurethane is polyurethane, which is called as polymer material for short, and is known as the fifth major plastic, and is widely used for manufacturing high-grade leather shoes, sneakers and the like. The polyurethane shoe material has the advantages of low density, soft texture, good elasticity, comfortable and light wearing, excellent wear resistance, bending resistance, high hardness, excellent shock absorption performance, anti-skid performance, collapse resistance and the like. The polyurethane shoe material is more and more popular with people due to durability and wearing comfort.
The density has a great influence on the performance of polyurethane, in order to give full play to the performance of polyurethane with different densities, the function of a sole is expanded, the comfort level of the sole is enhanced, dual-density polyurethane soles appear on the market, in order to prepare the dual-density polyurethane soles, the existing methods have two types, one type is to perform step-by-step casting molding on two shoe molds, the process steps of the method are complicated, two sets of molds need to be designed to correspond to the same sole, the other method is to arrange a lower mold on the mold to correspond to two different upper molds, namely a three-way mold, the mold is large in size, heavy in body and inconvenient to operate.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art, the utility model provides a rotatable polyurethane dual density shoe mould.
in order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a rotatable polyurethane dual density shoe mold, includes the last mould and the lower mould of mutually supporting, its characterized in that: the upper die comprises a connecting part and a forming part which are connected with each other, and a first section die and a second section die are respectively arranged on two opposite side surfaces of the forming part.
The connecting part and the forming part are connected through a rotatable fixing pin.
The connecting part is connected with the lower die in a matching way through a rotating shaft.
One end of the fixing pin is connected with the forming part through a spring.
And the front end of the forming part of the upper die is provided with a stretching handle.
the lower die is provided with a die locking handle.
The utility model has the advantages that:
The utility model discloses an go up the mould and set up to the double-sided type, go up and be connected with rotatable fixed pin between the connecting portion of mould and the shaping portion, consequently can realize the change of first section mould and second section mould through the rotation, realized the last mould and the lower mould integration of dual density shoes mould on a mould, greatly reduced the volume and the weight of mould, it is more nimble convenient to carry out the change operation of moulded die with rotatory mode simultaneously.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
As shown in figures 1 and 2 of the drawings,
The utility model provides a rotatable polyurethane dual density shoe mold, includes mould 2 and lower mould 1, its characterized in that of mutually supporting: the upper die 2 comprises a connecting part 22 and a forming part 21 which are connected with each other, and a first die and a second die are respectively arranged on two opposite side surfaces of the forming part 21.
The connecting part 22 and the forming part 21 are connected through a rotatable fixing pin 6.
The connecting part 22 is connected with the lower die 1 in a matching way through the rotating shaft 3.
one end of the fixing pin is connected with the forming part 21 through a spring 7.
The front end of the forming part 21 of the upper die 2 is provided with a stretching handle 4.
The lower die 1 is provided with a die locking handle 5.
The working process and principle of the utility model are briefly described as follows: under the normal state, under the action of the spring 7, the forming part 21 and the connecting part 22 of the upper die 2 are tightly attached, when the forming surface of the upper die 2 needs to be replaced, the stretching handle 4 is pulled, the spring 7 is stretched, the contact surface between the forming part 21 and the connecting part 22 is separated, because the rotatable fixing pin 6 is connected between the forming part 21 and the connecting part 22, the effect of mutual replacement of the first die and the second die can be achieved by rotating the forming part 21, after the forming part is rotated to the position, the stretching handle 4 is loosened, the restoring effect of the spring 7 enables the forming part 21 and the connecting part 22 to be tightly attached, when the die is required to be closed and formed, the stretching handle 4 is pushed to enable the upper die 2 to rotate around the rotating shaft 3, when the forming surface corresponding to the upper die 2 and the lower die 1 are correspondingly engaged, the upper die 2 and the lower die 1 can be fastened through the die locking.
The utility model discloses a key lies in through connecting portion 22, shaping portion 21, the design of fixed pin 6 and spring 7 has realized adopting rotatory mode to accomplish the shaping face change process of mould 2, pulling spring 7 makes the shaping portion 21 and the connecting portion 22 separation back of tightly laminating, can effectively avoid the friction that the contact surface of shaping portion 21 and connecting portion 22 produced, thereby reduce rotatory required dynamics, the rotation process is more nimble, because the rotation process can not cause the friction between shaping portion 21 and the connecting portion 22, thereby protect the mould effectively, the service life of mould is prolonged.
The foregoing embodiments and description have been provided to illustrate the principles and preferred embodiments of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
