Abstract

The utility model relates to a rubber leather cup demoulding clamp structure, which comprises a die holder, wherein the die holder is provided with a plurality of pressing blocks corresponding to the rubber leather cup, the pressing blocks are only provided with a single circle of bulges, and the bulges are tightly embedded in the outer side concave part of the rubber leather cup; the utility model utilizes the pressing block without the bulge inside the upper mold core, so that the rubber part which is taken on the lower mold can freely deform and move, thereby facilitating the demolding; the acting force of the pressing block and the middle die which are combined together is larger than the friction force of the lower die to a product, and the demolding effect can be realized under the condition that the demolding agent is not used.

Description

Rubber leather cup demoulding clamp structure

Technical Field

The utility model belongs to the automobile spare and accessory part field, especially the drawing of patterns anchor clamps structure of rubber leather cup is the field.

Background

The plunger master cylinder of the automobile brake is popularized in the automobile industry and gradually replaces a piston master cylinder, the plunger master cylinder has better braking effect, particularly uses the latest TMC8E, the plunger leather cup of an upgraded version has more stable generated force and shorter braking distance, is suitable for the development and use of a new electronic brake of a new energy source in the future and is favorable for the development prospect of an automatic driving technology, but the leather cup has more complex structure, higher performance requirement and higher manufacturing cost, has higher requirement on the skill level of workers and the future automatic production, the rubber product structure is difficult to demold from a mold, and under the common condition, as shown in the figure, the friction force caused by the characteristics of a lower mold core of the mold is larger than that of a middle mold core, the product is easy to demold from the lower mold and cannot adopt an automatic demolding mechanism, so that the demolding is very difficult, and the product which is demolded is passed through the middle mold, the risk of scratching is high, and the quality risk is high; therefore, the friction force of the middle mold needs to be increased, the friction force of the lower mold needs to be reduced, a special release agent needs to be used for solving the problem, the release agent is expensive, and is sprayed every 2 molds, one bottle of the release agent is about one hundred yuan, at least nearly two hundred bottles are needed in one year, and the cost of nearly two ten thousand yuan is increased by only one auxiliary process; in addition, the mold release agent easily causes mold pollution and is difficult to clean and maintain.

SUMMERY OF THE UTILITY MODEL

The object of the present invention is to provide a demolding clamp suitable for long-term use and economical in use.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model provides a rubber leather cup drawing of patterns anchor clamps structure, includes the die holder, be equipped with the briquetting that a plurality of and leather cup correspond on the die holder, only be equipped with the single circle arch in the briquetting, and protruding outside depressed part of closely inlaying locating the rubber leather cup.

As the utility model discloses a further optimization scheme, the briquetting is covered and is equipped with the rubber layer.

As a further optimization scheme of the utility model, the briquetting is covered and is equipped with the brass layer.

The beneficial effects of the utility model reside in that:

1) the utility model utilizes the pressing block without the bulge inside the upper mold core, so that the rubber part which is taken on the lower mold can freely deform and move, thereby facilitating the demolding; the acting force of the pressing block and the middle mold is larger than the friction force of the lower mold to the product, so that the demolding effect can be realized without using a demolding agent;

2) not only reduces partial cost, but also avoids the pollution of the mold release agent, and avoids the difficult problem of cleaning.

FIG. 5 is a schematic view of the assembly structure of upper, middle and lower mold cores in the prior art;

in the figure: 1. a die holder; 2. briquetting; 21. a protrusion; 3. an upper mold core; 4. a middle mold core; 5. a lower mold core; 6. a rubber cup; 61. a recessed portion.

Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

As shown in fig. 1 to 5, the rubber cup demolding clamp structure comprises a die holder 1, wherein a plurality of press blocks 2 corresponding to rubber cups 6 are arranged on the die holder 1, the number of the press blocks 2 on the die holder depends on the number of die cores on each die, and the positions of the press blocks 2 on the die holder 1 are the same as the positions of the die cores;

as can be seen from the structural comparison between FIG. 2 and FIG. 5, the briquetting in FIG. 2 has only one circle of protrusions, while the upper die core shown in FIG. 5 has two circles of protrusions; in addition, two circles of bulges are arranged at the bottom of the upper mold core, and the circle of bulges which are more than the pressing block are embedded in the concave part close to one side of the lower mold core, so that the side edge of the inner side of the rubber cup cannot deform freely when the rubber cup is discharged, and the demolding is difficult;

therefore, only a single circle of bulge 21 is arranged in the pressing block 2, and the bulge 21 is tightly embedded in the concave part 61 at the outer side of the rubber cup 6, so that the pressing block 2 does not have a bulge inside the upper mold core, and the rubber part embedded on the lower mold can freely deform and move, thereby being convenient for demolding;

when the device is used for demolding, the upper mold core 3 is firstly opened, the pressing block 4 is placed into the mold cavity to press a product, the pressing block is accurately positioned on the product, and then the protrusions are tightly embedded in the concave parts of the rubber leather cups, so that the acting force of the pressing block and the middle mold is greater than the friction force of the lower mold on the product, and meanwhile, one less protrusion is embedded in the mold core on the pressing block 2, so that the free deformation movement of a rubber part embedded on the lower mold is not influenced, and the demolding is facilitated;

for the product with thick wall and low hardness of the sizing material, so that the force for pushing down the mold is large, the pressing block can be made of brass material, or a brass layer is covered on the pressing block 2; the brass material is soft in texture and the hardness of the brass material is less than that of the die, so that the die is prevented from being damaged by the pressing block;

for products with thin wall thickness, high product hardness and small force for pushing down the mold, rubber materials can be used or a rubber layer is covered on the pressing block 2, so that the thin wall products are prevented from being damaged by the brass materials during demolding, and the manufacturing cost of the pressing block is also reduced.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
