Description

Technical Field

[0001] The utility model relates to a rubber mold locking device suitable for multilayer boards and belongs to the technical field of rubber molds. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Figure 1 As shown, the automotive rubber product is between the upper template and the middle template. During the mold opening process, when the oil cylinder pushes up the upper template, due to the adhesion problem of the product or the vacuum state, the middle template is lifted up together and the product cannot be taken out, resulting in difficulty in demolding the product. The middle template needs to be pried down manually to take out the product. Not only is the work efficiency low, but brute force may leave scratches on the product surface, which needs to be repaired and polished later. In addition, when prying, the middle template will fall instantly, or damage the mold, or injure people, which is very unsafe. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model connects and fixes the middle template and the lower template through a locking mechanism, so that when the oil cylinder drives the upper template to move upward, the middle template remains in place and the two are separated, thereby taking out the rubber product in the core.

[0004] The technical solution adopted by the utility model is a rubber mold locking device suitable for multi-layer plates, comprising an upper mold plate, a middle mold plate, a lower mold plate, and a vulcanizer heating plate which are sequentially installed from top to bottom, a core is arranged inside the upper mold plate and the middle mold plate, the core is connected to the upper mold plate by connecting screws, a hanging plate is installed on the side wall of the upper mold plate, and the middle mold plate and the lower mold plate are connected and fixed by a locking mechanism.

[0005] Furthermore, the locking mechanism includes a locking template and a locking screw. The locking template is installed on the side walls of the middle template and the lower template and is fixed by the locking screw.

[0006] Furthermore, the hanging plate is connected to the upper template by bolts.

[0007] The utility model discloses a rubber mold locking device suitable for multi-layer plates. Compared with the prior art, the middle mold plate and the lower mold plate are connected and fixed by a locking mechanism, so that when the oil cylinder drives the upper mold plate to move upward, the middle mold plate is fixed by the locking mechanism and the two are separated, so that the rubber product in the core can be taken out, the work efficiency is improved, the product yield is guaranteed, the mold damage is avoided, and the operation safety is improved.

[0012] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0013] In order to further understand the content of the utility model, this technical solution is further explained below in conjunction with specific implementation methods.

[0014] Embodiment 1:

[0015] like Figure 2As shown, this embodiment provides a rubber mold clamping device suitable for multilayer boards, including an upper mold plate 1, a middle mold plate 2, a lower mold plate 3, and a vulcanizer heating plate 11 installed in sequence from top to bottom, the vulcanizer heating plate 11 is connected to the lower mold plate 3 by screws, a core 9 is provided between the upper mold plate 1 and the middle mold plate 2, the core 9 is connected to the upper mold plate 1 by connecting screws 10, a hanging plate 4 is connected to the side wall of the upper mold plate 1 by bolts, and a locking mechanism connects and fixes the middle mold plate 2 and the lower mold plate 3. Specifically, the locking mechanism includes a locking mold plate 7 and a locking screw 8, the locking mold plate 7 is installed on the side walls of the middle mold plate 2 and the lower mold plate 3, and a screw hole is provided on the locking mold plate 7, and the locking screw 8 passes through the locking mold plate 7 to connect the middle mold plate 2 and the lower mold plate 3 together. The oil cylinder 12 is located below the hanging plate 4. A support plate 5 is installed on the pressure shaft of the oil cylinder 12 and fixed by a nut 6. When the mold needs to be opened, the pressure shaft of the oil cylinder 12 extends to drive the support plate 5 to move upward, and then the support plate 5 contacts the hanging plate 4 and drives the hanging plate 4 and the upper template 1 to move upward together. The middle template 2 and the lower template 3 are fixed together by a locking mechanism, so that the upper template 1 is separated from the middle template 2, so that the product is taken out, which improves work efficiency, ensures product yield, avoids the middle template 2 hitting the lower template 3 and causing damage to the mold, and also avoids workers prying open the middle template 2, thereby improving operational safety.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
