Abstract
The utility model discloses a device for preparing a PVC (polyvinyl chloride) hardness sample, which comprises a die frame, wherein the die frame is provided with a plurality of die cavities which are arranged in a rectangular array at the same interval, vent holes are formed in the side walls of the die cavities, and pressing plates are respectively covered on the upper surface and the lower surface of the die frame. The utility model can manufacture a plurality of standard samples of the hardness block at one time, fully utilizes the molding area of the vulcanization molding machine, improves the efficiency by more than 100 percent, and improves the aesthetic property of the sample by molding the sample at one time without cutting.
Description
Technical Field
The utility model relates to a hardness sample forming device, in particular to a device for preparing a PVC hardness sample.
Background
The existing hardness block mold frame only has 1 or 4 acupuncture points, only 1 or 4 hardness blocks can be prepared at the same time, the prepared hardness blocks need to be cut for the second time, the sample preparation efficiency is low, and the bubble phenomenon is easy to occur in the preparation process.
Disclosure of Invention
According to the technical problem to be solved, the device for preparing the PVC hardness test sample is provided.
In order to achieve the purpose, the device for preparing the PVC hardness sample comprises a die frame, wherein the die frame is provided with a plurality of die cavities which are arranged in a rectangular array at the same interval, vent holes are formed in the side walls of the die cavities, and pressing plates are respectively covered on the upper surface and the lower surface of the die frame.
Further, 4-16 mold cavities are arranged.
Further, 9 mold cavities are provided.
Further, the distance between the mold cavities was 27 mm.
Furthermore, vent holes which are arranged in a shape like a Chinese character 'jing' are arranged in the partition between the die cavity and are communicated with the vent holes on the inner wall of the die cavity.
Has the advantages that: according to the device for preparing the PVC hardness sample, a plurality of hardness block standard samples can be prepared at one time, the forming area of a vulcanization forming machine is fully utilized, the efficiency is improved by more than 100%, the samples are formed at one time, cutting is not needed, and the attractiveness of the samples is improved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
In the figure: 1 is a mould frame; 2 is a mold cavity; and 3 is an exhaust hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the present invention.
As shown in fig. 1 and 2, the device for preparing the PVC hardness test sample comprises a mold frame, wherein the mold frame 1 is provided with a plurality of mold cavities 2 which are arranged in a rectangular array at the same interval, the side walls of the mold cavities 2 are provided with exhaust holes 3, and the upper surface and the lower surface of the mold frame 1 are respectively covered with a pressing plate.
Wherein, the plasticized PVC material is cut and filled into each mold cavity, the upper surface and the lower surface of the mold frame are respectively pressed by a pressing plate, the mold frame is put into a vulcanization molding machine to complete shaping, and 9 hardness block samples meeting the requirements can be obtained at one time after being taken out.
As shown in fig. 1, the mould cavities 2 are provided with 4-16.
As shown in fig. 1, the number of the mold cavities 2 is 9.
As shown in fig. 1, the distance between the mould cavities 2 is 27 mm.
Wherein, the distance between the mold cavities 2 is 27mm by verification, and the 9 mold cavities 2 are selected to fully select the effective area of the molding machine and prevent the cross flow and the overlapping.
As shown in fig. 2, the partition between the mold cavity 2 and the mold cavity 2 is provided with vent holes 3 arranged in a shape of a Chinese character jing and communicated with the vent holes 3 on the inner wall of the mold cavity 2.
Wherein, the vent hole 3 on the inner wall of the die cavity 2 can be discharged through the # -shaped vent hole 3 in the partition, thereby preventing bubbles from being generated during molding.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
The above examples are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention, and all designs identical or similar to the present invention are within the scope of the present invention.
