New description: [New technical field] The creation department is about a hot press forming mold, especially a ball core molding which can shorten the processing time, reduce the product defect rate, and reduce the manufacturing cost and the damage rate. The mold structure is improved. [Prior Art] According to the method of manufacturing the early golf ball core, the rubber raw material φ is molded into a mold by a group of rough embryo molding to obtain a non-spherical rough embryo of a desired weight and size, and then A plurality of rough wins are manually placed in a ball molding die, and the ball core molding die is generally mounted on a hot press forming machine, and is heated and formed by the machine to form the rough embryo into a predetermined elasticity and strength. The spherical ball core; in this manufacturing method, when the rubber material is pressed into a rough embryo, the rough embryos are manually picked up by the rough embryo molding die, and then carefully placed in the ball core molding die. In the cavity of the mold, it is very expensive, labor and man-hours, which can not effectively improve the production efficiency, and if it is placed carelessly, it will cause defective products, so the product cost is high, and then it needs two large machines, respectively It is used for the rough embryo molding die and the ball core molding die, so the investment cost of the equipment is increased, and the required room space is large. In order to improve the above-mentioned shortcomings, there is a spherical core forming die as shown in the new patent application No. 5 16498 of the annex, which mainly includes a bottom mold, a middle core and a top core, and the like. The contact surface is provided with a plurality of concave hemispherical upper and lower mold grooves to form a spherical core shape, and the middle mold is provided with a plurality of penetrating feed holes and communicating with the lower mold groove, and the top mold system can be pressed. At the top of the middle mold, a plurality of top columns are arranged on the bottom surface thereof, and can be inserted into the feed holes, and the middle part of the mold body is covered with a plurality of electric heating pipes, and the structure is matched with the traditional press mold and the feeding mold. The injection of the rough embryo can be completed on the same machine and further heated into a spherical core, thereby achieving a significant reduction in labor costs and unprepared investment, improving production efficiency, and reducing product defect rate. However, it is found that the conventional spherical core molding structure still has the following disadvantages in practical application: 1. The bottom surface of the top mold is provided with a plurality of top pillars protruding downward, and the position and size of the top pillar are required to be quite accurate. Therefore, the manufacturing cost of the mold is high. 2. The top pillar protruding downward from the bottom surface of the top mold is slender and easy to be damaged by human operation. If it is damaged, it needs to be disassembled and replaced. If it is not replaced immediately, the defective product will occur, resulting in inconvenient use and working hours. Waste and increased costs. 3. When molding, in addition to the top and bottom molds need to be heated by the heating plate, the middle mold also needs to be heated to a predetermined temperature by the electric heating tube, so that the operator is easily burnt if accidentally, and the operation safety is not good. . [New content] The creator has a high cost of mold manufacturing and damage, and the operator is prone to burns due to the well-known structure of the ball core molding mold. It is the idea of creating and testing the sample. And many revisions and improvements, this is the creation of this creation. M312415
