Description

Technical Field

[0001] This utility model belongs to the technical field of gating grinding, and particularly relates to an automatic gating grinding device. Background Technology

[0002] Plastic products are various products manufactured using plastics as raw materials through a variety of processing technologies, such as containers, components, and packaging materials. These products are lightweight, corrosion-resistant, and easy to mold, and are widely used in various industries. Thermosetting molds, as an important tool in the production of plastic products, can solidify plastic materials at high temperatures to form specific product shapes and achieve the required properties.

[0003] The sprue is the channel through which molten material enters the mold cavity. After the product is molded, the excess sprue portion needs to be removed. Common thermosetting materials are hard and brittle, so their properties must be considered when handling the sprue. There are two main methods for handling sprues: automatic shearing and manual removal. Automatic shearing allows control over the amount of sprue removed, ensuring a smooth sprue root. When the mold structure cannot achieve automatic shearing, manual removal of the sprue is usually used. Due to the material properties, manually removing the sprue can easily lead to irregular fractures, burrs, or cracks, and may even damage the product itself. This phenomenon has always existed in thermosetting product molding, affecting product quality and cost. Utility Model Content

[0004] This invention provides an automatic grinding device for the gating system. This device uses a grinding wheel to grind the gating system, which can solve the problem of easy breakage or even damage to the product body caused by manually breaking the gating system of thermosetting products.

[0005] The technical solution adopted is:

[0006] An automatic grinding device for gating channels includes a grinding wheel, a grinding wheel, a positioning block, a slide, and a fixing frame.

[0007] Its key technical points are:

[0008] The grinding wheel is fixed to one end of the output shaft of the grinding machine.

[0009] A positioning block is provided in front of the grinding wheel.

[0010] The positioning block has a positioning block through hole, and the edge of the grinding wheel extends out from the positioning block through hole.

[0011] The positioning block is fixed to the edge of the slide.

[0012] The slide is equipped with a slider.

[0013] The mounting bracket is fixed to the slider below and is used to secure the product.

[0014] Its advantages are:

[0015] This device uses a sliding block to push the product on the fixed frame closer to the grinding wheel. The product's gate is directly opposite the grinding wheel. As the fixed frame moves forward, the grinding wheel grinds the sprue. The sprue residue on the product is continuously ground away by the grinding wheel until the fixed frame collides with the positioning block, at which point the sprue residue is completely ground away. This solves the problems of easy breakage, burrs, and even damage to the product itself that occur when manually breaking the sprue of thermosetting products, thus avoiding affecting product quality and reducing costs.

[0022] Reference Figures 1-4 An automatic grinding device for gating channels includes a grinding wheel 1, a grinding wheel 2, a positioning block 3, a slide 6, and a fixing frame 4.

[0023] The grinding wheel 2 is fixed to one end of the output shaft of the grinding machine 1.

[0024] A positioning block 3 is provided in front of the grinding wheel 2.

[0025] The positioning block 3 has a vertically arranged elongated positioning block through hole 8. The edge of the grinding wheel 2 extends out from the positioning block through hole 8, and the extension amount is equal to the depth of the groove to be ground (e.g., 0.1 mm).

[0026] Positioning block 3 is fixed to the edge of slide 6.

[0027] A slider 5 is mounted on the slide 6 via a linear bearing.

[0028] The mounting bracket 4 of product 7 is fixed to the slider 5 below.

[0029] Product 7 is placed on the mounting bracket 4.

[0030] This product 7 is a three-phase switch. The shape of the mounting bracket 4 matches the shape of the product 7. The product 7 can be fixed in the positioning groove of the mounting bracket 4. The rear edge protrusion of the product 7, which is similar to a U-shaped bracket, is stuck in the short side behind the groove of the mounting bracket 4, and the front edge protrusion of the product 7 is stuck in the upper front edge of the positioning groove of the mounting bracket 4.

[0031] The mounting bracket 4 is provided with a positioning groove to fix the product 7. The product 7 is placed on the mounting bracket 4 and must not exceed the mounting bracket 4. The product 7 and the positioning block 3 are configured such that when the mounting bracket 4 and the positioning block 3 collide, the grinding depth of the grinding wheel 2 on the product 7 exactly matches the set depth. The purpose of this design is to ensure that when the mounting bracket 4 and the positioning block 3 collide, the product 7 will no longer be ground by the grinding wheel 2.

[0032] Working principle: Product 7 is placed on the fixed frame 4. The manually pushed slider 5 moves back and forth by the bearing to push product 7 on the fixed frame 4 closer to the grinding wheel 2. At this time, the gate position of product 7 is directly facing the grinding wheel 2. As the fixed frame 4 moves forward continuously, the sprue residue on product 7 is continuously ground by the grinding wheel 2 until the fixed frame 4 collides with the positioning block 3, and the sprue residue is also completely ground away, thus solving the problems of burrs and damage to the product caused by manually breaking the sprue.

[0033] The grinding wheel 1 and the slide 6 are set on the worktable.
