Description

L type part surface vulcanization rubber coating mould

Technical Field

The utility model relates to a rubber coating equipment field, concretely relates to surface vulcanization rubber coating mould of L type part.

Background

Aiming at the problem that the metal parts are not allowed to be in direct contact with the battery and the battery core in the lithium battery industry, the problem that the metal parts are in direct contact with the surface of the battery and the battery core is solved by a method of encapsulating the surfaces of the parts in direct contact with the battery and the battery core, but the existing encapsulation methods, such as infiltration encapsulation, surface double-sided adhesive adhesion and the like, have the phenomena that encapsulation is not firm, the parts are easy to fall off, and the encapsulation thickness is difficult to control!

In order to solve the above problems, the technical staff have the following technical solutions through intensive research.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the application provides a surface vulcanization rubber coating mould of L type part, and the rubber coating is firm, is difficult for droing, and thickness control is accurate.

In order to achieve the purpose, the following technical scheme is adopted:

an L type part surface vulcanization rubber coating mould comprises an upper mould, a lower mould and a L type placing cavity formed by the upper mould and the lower mould in a vertically pressing mode, wherein one side portion of the upper mould is a pressing and guiding wedge with a downward inclined surface, one side of the lower mould is matched with the pressing and guiding wedge to form a sliding wedge, and the upper mould is pressed downwards to enable the pressing and guiding wedge to move downwards along the sliding wedge so as to force the upper mould to simultaneously displace towards the bottom and the inner side portion of the lower mould in a micro mode.

Further, the pressing device comprises an X-direction pressing assembly parallel to the bottom of the lower die, wherein the X-direction pressing assembly comprises an X-direction pressing screw and a pressure injury prevention gasket so as to press the L type part to the inner side of the lower die.

Furthermore, the Z-direction correcting component is vertical to the bottom of the lower die and comprises a Z-direction correcting pin vertically arranged at the bottom of the lower die and a Z-direction correcting hole arranged on the upper die.

By adopting the technical scheme, the method has the following technical effects:

1. the utility model discloses a L type part surface vulcanization rubber coating mould, a lateral part of going up the mould is the decurrent oblique wedge of leading that compresses tightly in inclined plane, one side of bed die with compress tightly lead the oblique wedge cooperation and form the slip oblique wedge, thereby it makes to compress tightly to lead the oblique wedge and move down along the slip oblique wedge and force the bottom and the interior part of mould down and trace displacement simultaneously to the surface of L type part compresses tightly in step, thereby make L type part surface rubber coating thickness reach predetermined thickness and ensure the thickness uniformity.

2. The use cost of customers is reduced, and the prior proposal needs to frequently replace the surface rubber coating or parts during the use process, so the prior proposal does not need to replace any parts during the use process

FIG. 2 is a diagram of the usage state of the mold for vulcanization and encapsulation of the surface of the L-type part according to the present invention;

in the drawing, an upper die-10, a pressing and straightening wedge-11, a lower die-20, a sliding wedge-21, an L-type placing cavity-30, a L-type part-40, an X-direction pressing screw-51, a crush-proof gasket-52, a Z-direction straightening pin-61 and a Z-direction straightening hole-62 are arranged.

Detailed Description

The invention will now be further described with reference to specific examples, which are intended to illustrate, but not to limit the invention further.

With reference to fig. 1-2, the present application provides an L type part surface vulcanization rubber coating mold, including an upper mold 10, a lower mold 20, and a L type placement cavity 30 formed by pressing the upper mold 10 and the lower mold 20 up and down, a side portion of the upper mold 10 is a pressing and guiding wedge 11 with a downward inclined surface, one side of the lower mold 20 is matched with the pressing and guiding wedge 11 to form a sliding wedge 21, pressing down the upper mold 10 makes the pressing and guiding wedge 11 move down along the sliding wedge 21 so as to force the upper mold 10 to move down to the bottom and the inner side portion of the lower mold 20 at the same time in a micro-displacement manner, so as to synchronously press the surface of a L type part 40, thereby making the surface rubber coating thickness of the L type part 40 reach a predetermined thickness and ensuring thickness consistency.

In this embodiment, as shown in fig. 2, an X-direction pressing assembly parallel to the bottom of the lower mold 20 is further included, and the X-direction pressing assembly includes an X-direction pressing screw 51 and a crush-proof washer 52 to press the L-type part 40 to the inner side of the lower mold 20, so as to prevent the L-type part 40 from shifting during the pressing process of the upper mold 10 and the lower mold 20.

In this embodiment, as shown in fig. 2, the mold further includes a Z-guide centering assembly perpendicular to the bottom of the lower mold 20, the Z-guide centering assembly includes a Z-guide centering pin 61 vertically disposed at the bottom of the lower mold 20 and a Z-guide centering hole 62 disposed on the upper mold, and the Z-guide centering assembly plays a role in positioning during the pressing process of the upper mold 10 and the lower mold 20, so as to achieve a better vulcanization encapsulation effect.

By adopting the technical scheme, the specific working process is as follows:

1. firstly, pressing silica gel paste into a sheet, and then pasting the sheet on an L type part which is brushed with glue;

2. placing the L type part into the L type placing cavity 30, and fixing the L type part in the X direction by matching the anti-crushing gasket with the X-direction compression screw;

3. the upper die is arranged on the lower die, and the Y-direction movement of the upper die is limited by the Z-direction alignment pin;

4. when the mould is placed on vulcanizing equipment for pressing, heating and vulcanizing, the upper and lower moulds are matched according to a certain rule and the movement amount of the upper and lower moulds is controlled to control the rubber coating thickness under the combined action of the upper and lower pressing and the pressing and straightening wedges of the vulcanizing equipment.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
