Problems solved by technology

[0004] In the prior art, when the soft rubber product is notched, the soft rubber product is fixed on the lower mold. When the soft rubber product is punched out in this way, waste will be left on the lower mold, which requires multiple sets of demoulding tools. At the same time, the product and waste are demoulded, and the production efficiency is low. At the same time, the service life of the lower mold will be shortened, and the lower mold needs to be replaced frequently, resulting in low production efficiency.

Embodiment 1

[0031] like Figure 1-4As shown, an intelligent incision device for soft rubber products includes an upper mold 1, the right side of the upper mold 1 is sealed and fitted with a lower mold 2, the upper mold 1 is fixedly connected to the mold fixing plate 3, and the lower mold 2 is fixedly connected to the fixing plate, Both the upper mold 1 and the middle part of the lower mold 2 are provided with a plurality of product mold grooves 4, and the product mold grooves 4 are connected through the flow channel 401, and the joints between the product mold groove 4 and the flow channel 401 are provided with raised cutters. The protruding cutter 6 is set to make the thickness of the connection between the product cavity 4 and the flow channel 401 thin during the injection molding process, so as to facilitate the manual separation of the waste rubber and the product in the later stage; the flow channel 401 includes an I-shaped main flow Channel 4011, the I-shaped main channel 4011 commu...

Embodiment 2

[0039] Based on the above-mentioned embodiment 1, the above-mentioned device can only achieve injection molding, demoulding, and the separation point of the pre-fabricated product and waste material, but cannot completely separate the product and waste material, and due to the convex setting of the cutter, it will cause a problem in the injection process. , leading to the increase of time for injecting soft rubber into the product cavity 4, resulting in low production efficiency. At the same time, in the prior art, when using a telescopic cutter to completely cut and separate the product and waste, it often leads to burrs on the edge of the cut product , and the surface of the cutter after cutting carries a part of waste rubber particles, so that in the subsequent new product processing and manufacturing process, the product is mixed with waste particles, which affects the quality of the produced product. In order to solve the above problems, the inventor made further improvemen...

Abstract

The invention belongs to the technical field of soft rubber injection molding, and particularly relates to an intelligent notching device for soft rubber products. The intelligent notching device comprises an upper mold, a lower mold is hermetically matched with the right side of the upper mold, mold fixing plates are symmetrically arranged on the side, deviating from the lower mold, of the top of the upper mold, a plurality of product mold grooves are formed in the middle of each of the upper mold and the lower mold, and the plurality of product mold grooves communicate through a runner. According to the intelligent notching device for the soft rubber products, through mutual cooperation of a trapezoidal electromagnetic plate, a trapezoidal blade and the like, before soft rubber is injected, the trapezoidal electromagnetic plate is controlled to be connected with a first current, so that heat generated by electrification of the trapezoidal electromagnetic plate is transmitted to the trapezoidal blade through a heat conduction layer, waste rubber on the trapezoidal blade and a port of a square through groove is molten and adheres to the trapezoidal blade, the situation that particles on the last waste rubber flow into the product mold grooves, and consequently produced products have flaws is avoided, and therefore the quality of the produced products is improved.

Description

technical field [0001] The invention belongs to the technical field of soft rubber injection molding, and in particular relates to an intelligent incision device and method for soft rubber products. Background technique [0002] Soft rubber is made of plastic through injection molding. It feels soft at room temperature. Many people call it "soft rubber". In the general plastic industry, PP, PE and other plastics with light specific gravity and relatively low surface hardness are called soft rubber. [0003] Chinese patent CN113246368A discloses a sleeve punching die, including a punch and a die, the die is provided with a punching cut and a feed port perpendicular to the punching cut, and one end of the punch is located above the punching cut And it can be moved into the punching opening, and the other end is connected with a fixing plate, and there are several sets of sleeve components fixed on the fixing plate to fix the material to be punched; the inside of the punch is p...
