Description

[Technical field]

[0001] The utility model relates to the technical field of molds, in particular to a rubber molding mold which is convenient for taking molds. [Background Technology]

[0002] Fluororubber has good sealing properties and strong corrosion resistance, but the fluidity of fluororubber after cooling is poor. Therefore, when processing fluororubber products, the raw materials need to be placed in the mold cavity, and the fluororubber needs to be heated to make it flow and form in the cavity.

[0003] For example, Chinese patent CN218838329U discloses a vulcanization mold for a fluororubber sealing ring, which includes a first mold shell, a second mold shell and a mold core; the first mold shell and the second mold shell are provided with slide grooves on the left and right sides, the first mold shell is connected to a hinge on the rear side for easy opening and closing, and mold cores are placed inside the first mold shell and the second mold shell, together forming a molding cavity.

[0004] However, this double-layer mold shell plate design makes it difficult to remove products with barbs, and the fluidity of fluororubber is relatively poor. The current material is prepared in the form of a cylinder and placed on the middle plate mold core. The rubber is easily tilted and causes product shortages. There is a fluororubber product on the current market that has barbs both inside and outside the product. The three-layer plate design commonly used in the production of this product requires the internal barbed small mold core to be movable before the mold can be removed. Because the mold core is very small, the mold removal operation is very difficult and the time efficiency is very low. In addition, the mold core is small and is easily misaligned when repeatedly placed in the positioning hole, causing damage to the mold.

[0005] Based on this, the utility model designs a rubber molding mold which is convenient for taking out the mold to solve the above problems. [Contents of the utility model]

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a rubber molding mold which is easy to take out the mold.

[0008] The upper side of the lower plate is provided with a mounting groove for accommodating the lower plate strips and the middle plate; the middle plate is composed of two symmetrical beam templates; a plurality of cavities are formed between the lower plate strips and the middle plate; a plurality of material pools connected to the cavities are provided on the upper side of the middle plate; the plurality of material pools are evenly distributed on the middle plate at equal intervals;

[0009] The bottom of the pressing plate is fixedly provided with mold cores at equal intervals, and the mold cores are plugged into the material pool; positioning components are also installed on the lower plate strips and the middle plate.

[0010] Furthermore, the middle plates are provided in three groups, thereby effectively improving the forming efficiency.

[0011] Furthermore, the cross section of the mounting groove is configured as a trapezoid that is wider at the top and narrower at the bottom, and the side edges of the lower plate strips and the middle plate are configured as inclined surfaces that cooperate with the side edges of the mounting groove.

[0012] Furthermore, the length of the lower plate strip is greater than the length of the lower plate, the pressing plate and the middle plate.

[0013] Furthermore, a plurality of bottom cores are fixedly installed at equal intervals on the upper side of the lower plate slats, and a barb block is fixedly installed on the top of the bottom core.

[0014] Furthermore, a plurality of beam mold grooves are evenly and evenly provided at equal intervals on the inner side of the beam mold plate, and a mold cavity is formed between the beam mold grooves and the bottom core, the barb blocks and the lower plate strips; inner grooves are provided on the inner sides of both ends of the beam mold plate.

[0015] Furthermore, a guide surface is provided on the top of the material pool to facilitate the insertion of the mold core.

[0016] Furthermore, the positioning assembly includes a slide groove and a slider, the two sliders are symmetrically fixedly installed on the upper side of the lower plate slats, and the bottom of the beam template is symmetrically provided with slide grooves, which are limitedly slidably connected to the sliders.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model combines the lower plate strip and the middle plate through a positioning component, then puts the raw material into the material pool on the middle plate, preheats the lower plate strip and the middle plate with the raw material, and then puts them into the installation groove on the lower plate, and ensures the matching gap of the beam mold through the inclined surfaces used in conjunction with the installation groove arranged on the lower plate strip and the side of the middle plate, and the beam mold will not move during the glue feeding process, so that the mold line at the beam mold of the product can be beautiful; in addition, it is easy to operate when the whole group is placed and ejected; the pressing plate drives the mold core to be pressed in The mold cavity is closed in the material pool for molding; after molding, the lower plate strip whose length is greater than the lower plate, the pressure plate and the middle plate is ejected, so that the lower plate strip, the middle plate and the finished product molded in the mold cavity are ejected at the same time, and then the two beam templates are separated, and the molded finished product is taken out from the lower plate strip; by setting three groups of middle plates, preheating, molding and demolding can be carried out simultaneously, effectively improving the molding efficiency; the lower plate strip and two symmetrically arranged beam templates constitute a group of molding modules, the beam template is not easy to be damaged, and the life of the mold is increased;

[0019] In actual use, the small movable mold core commonly used in the current market needs to be engraved with hole numbers, which is difficult to operate and easy to damage the mold core; the utility model can use the lower plate strip, the lower plate and two symmetrically arranged bundle templates as an integral mold core, and the hole numbers can be engraved when processing the mold, which is more convenient;

[0020] At the same time, the beam template also has a venting effect, which can improve the phenomenon of poor air inclusion in the product; at the same time, through the material pool, the pressure plate squeezes the rubber into the cavity through the mold core; thus, there is no need to add weight to the rubber to solve the problems of material shortage and air inclusion, thereby avoiding the problems of extended burrs and high scrap rate caused by adding weight to the rubber.
