Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The application provides a can amputate car mould of waste material automatically, include thimble structure and support and press the structure. The thimble structure includes a thimble group, a regulating sheet 400, a first pressing plate 100 and a second pressing plate 200.
The thimble group includes a plurality of needle bars 300, and the one end of every needle bar 300 all is used for the butt at the fashioned product of mould intracavity, and the other end all is provided with the screw thread. The number of the adjusting sheets 400 is the same as that of the needle rods 300, and the adjusting sheets 400 are in threaded connection with the needle rods 300 in a one-to-one correspondence mode. The first press plate 100 includes through holes in the same number as the needle bars 300, through which the needle bars 300 are passed in one-to-one correspondence, and the respective regulating tabs 400 are located between the first press plate 100 and the product. The second pressing plate 200 is located on a side of the first pressing plate 100 away from the adjustment sheet 400, the second pressing plate 200 is provided with springs 230 whose number is consistent with that of the needle bars 300, and each spring 230 is sleeved on each needle bar 300 in a one-to-one correspondence manner.
The pressing structure comprises a pressing plate 700, the pressing plate 700 is arranged on one side of the product, which is far away from the first thimble structure, and the pressing plate 700 is used for pressing the joint position of the excess material of the product, so that the needle rod 300 and the pressing plate 700 shear and separate the product and the excess material of the connected product together.
The application provides an automobile mold, including thimble structure and support the pressure structure, the thimble structure includes thimble group, adjustment sheet 400, first clamp plate 100 and second clamp plate 200. Since the adjustment tabs 400 are screw-coupled with the needle bars 300 in the set of the upper needles, even if the lengths of the respective needle bars 300 are uniform, the respective needle bars 300 can be just and simultaneously brought into contact with the lower surfaces of products of different shapes by adjusting the positions of the respective adjustment tabs 400 on the respective needle bars 300. Moreover, since the spring 230 is disposed on the second pressing plate 200, when the second pressing plate 200 is pushed, the spring 230 on the second pressing plate 200 pushes the first pressing plate 100, the first pressing plate 100 pushes each adjustment tab 400, each adjustment tab 400 pushes the needle bar 300, and the needle bar 300 can push the product at the same time, so that the product is separated from the mold. The thimble structure in the above scheme can adjust the relative position of the needle bar 300 and can provide the same thrust to each needle bar 300 at the same time, so that the product pushing process becomes smoother.
Furthermore, if a product needs to be pushed preferentially at a specific point position in the process of pushing the product, the needle rod 300 corresponding to the specific position can be manually adjusted, so that the needle rod 300 can rotate relative to the adjusting sheet 400, the operation is convenient and fast, and different operation requirements can be met.
Furthermore, in this application, still be provided with and support clamp plate 700, support clamp plate 700 and needle bar 300 and set up respectively in the both sides of product, through needle bar 300 and support the shearing action between the clamp plate 700, alright will be located the product of mould and clout and cut the separation for the product need not follow-up manual separation again, has promoted machining efficiency. Particularly, due to the adoption of the thimble structure, an operator can adjust the needle rod 300 positioned at the joint of the product and the excess material upwards, so that the needle rod 300 preferentially shears the product and the excess material with the pressing plate 700, and then other needle rods 300 eject the product and the excess material out of the mold. So that the cutting and ejecting processes can be finished by one-time action of the thimble structure.
In order to facilitate shearing of the product and the remainder, in one embodiment, a sharp edge is disposed on a side of the pressing plate 700 facing the product.
According to some embodiments, the automobile mold further includes a first mold body 600, the first mold body 600 has a molding cavity, the molding cavity is used for molding the mold, a plurality of holes for each needle bar 300 to pass through are arranged in the molding cavity, a shearing groove 610 is arranged on a surface of the first mold body 600 facing away from the needle bars 300, the shearing groove 610 is arranged at a seam position of the product and the remainder, and the pressing plate 700 is aligned with the shearing groove 610 for inserting the pressing plate 700 into the shearing groove 610. The automobile mould further comprises a second mould body, the second mould body is matched with the first mould body 600 to define a forming cavity together, the second mould body is further provided with a protrusion, and when the first mould body 600 and the second mould body are combined, the protrusion is embedded with the shearing groove 610.
That is, during the injection molding of the product, since the protrusion of the second mold body occupies the position of the shear groove 610, the position of the shear groove 610 is left after the first mold body 600 is separated from the second mold body. In this way, it is convenient to extend the sharp edge of the pressing plate 700 into the shearing groove 610 to shear the seam position of the product and the oddment.
According to some embodiments, the adjustment tab 400 is a magnetic member, such as a magnet, and the adjustment tab 400 may be attached to the first pressure plate 100, thereby facilitating the securing of the needle bar 300 to the first pressure plate 100.
According to other embodiments, a side surface of the first pressure plate 100 facing the adjusting blade 400 is provided with counter bores, the number of the counter bores is the same as that of the adjusting blades 400, a cylindrical tube 500 is connected to a side of the adjusting blade 400 facing the first pressure plate 100, the cylindrical tube 500 is in clearance fit with the counter bores, and the cylindrical tube 500 is provided as a magnetic member. Such a structure enables each needle bar 300 to move in a straight line, and also facilitates the fixing of the needle bars 300 to the first presser plate 100.
According to some embodiments, the first presser plate 100 is coupled with guide posts 210, and the second presser plate 200 is provided with guide holes through which the guide posts 210 pass. In another embodiment, the second pressing plate 200 is connected to a guide post 210, and the first pressing plate 100 is provided with a guide hole through which the guide post 210 passes.
This can stabilize the process of the relative movement between the first and second platens 100 and 200.
According to some embodiments, a buffer 220 is disposed between the first pressing plate 100 and the second pressing plate 200, and the buffer 220 is silicone. Such a structure can prevent the second presser plate 200 from giving the first presser plate 100 excessive punching force.
According to some embodiments, a resilient member is disposed on the guide post 210. This makes it possible to make the pressure between the second presser plate 200 and the first presser plate 100 more moderate.
According to some embodiments, the spring is welded to the second pressure plate. This prevents the spring from coming off the second presser plate.
In this application, can adjust the high position of the needle bar 300 with the clout butt and be higher for when second clamp plate 200 moved up, preferred butt clout lifts up the clout slightly and conveniently shears, shears the clout after, continues again with the clout ejecting, then continues to move up second clamp plate 200 and makes the good product of each needle bar butt shaping again, in order ejecting the product, accomplish the secondary ejection of compact (ejecting clout for the first time, ejecting product for the second time) with this.
