At the same time, each technical feature in the invention can be combined interactively without contradiction and conflict.

[0025] In the prior art, because the bottle body of the glass bottle is mostly of a complex shape, the forming mold is generally of a half-open structure, and thus the forming mold includes an inevitable joint surface, and the bottle body of the glass bottle produced also includes an inevitable joint line. Figure 1 In the prior art, in order to process the recess 10 on the bottle mouth, a protrusion fixed with the forming mold is arranged on the glass bottle mouth mold, and because the forming mold needs to be opened, the protrusion is generally arranged on the inner wall of the forming mold in the direction consistent with the opening direction. Because the opening direction is generally perpendicular to the joint surface, the recess 10 is located at the vertical position of the joint line on the bottle body of the produced bottle, and because the label on the bottle body generally needs to block the joint line, the position of the recess does not match the label, thereby affecting the overall appearance of the product.

[0026] Therefore, the glass bottle mouth mold structure provided by the utility model can set the recess at the position coinciding with the joint line. Figures 2-3

[0027] ​A glass bottle mouth mold, comprising a mold body 100, which is also composed of two half molds, the two half molds are substantially mirror-symmetric, and the joint surface of the two half molds is a parting surface. A mold cavity 110 is arranged in the mold body 100, the shape of the mold cavity 110 is the same as the bottle mouth outer contour of the glass bottle to be produced, and the mold cavity 110 is also divided into two halves and symmetrically distributed on the two half molds. It can be understood that the mold cavity 110 is arranged in an up-down layout as a whole, the upper end of the mold cavity 110 is an opening, and the lower end is connected with the bottle body. A transversely arranged pin cavity 120 is further arranged on the mold body 100, the pin cavity 120 is arranged in a left-right direction as a whole, and the pin cavity 120 is arranged on the parting surface. A pin 200 capable of sliding in the left-right direction is arranged in the pin cavity 120, and an elastic member 300 is further arranged between the pin 200 and the mold body 100. It can be understood that the elastic member 300 forces the pin 200 to move away from the mold cavity 110. The function of the pin 200 is mainly to form a pit on the bottle mouth. Unlike the fixed pin in the prior art, the pin 200 of the utility model can slide left and right relative to the mold body 100. During production, the pin 200 is moved inward, so that the glass bottle forms the required pit on the outer side of the bottle mouth during blow molding. Since the pin is arranged on the parting surface, the pin 200 needs to be retracted during product demolding. Therefore, the elastic member 300 is arranged between the pin 200 and the mold body 100, so that the pin 200 is pushed away from the mold cavity 110 by the elastic member 300 during mold opening. During mold closing, external force is required to overcome the elastic force of the elastic member 300 to push the pin 200 inward, so as to form the required glass bottle product. Therefore, the pin 200 is provided with a driven part 210 on the outer side (i.e., the end away from the mold cavity). During mold closing, external force acts directly on the driven part 210, and then the driven part 210 generates an inward moving force on the pin, which overcomes the elastic force of the elastic member 300, so as to force the inner side of the pin 200 to protrude in the mold cavity 110, thereby forming the pit on the bottle mouth of the glass bottle. After the glass bottle is blow molded, the mold is opened, and the external force disappears. At this time, the driven part 210 no longer bears the force, and the elastic force of the elastic member 300 forces the pin 200 to move outward, and the pin 200 is separated from the molded product, so that the product can be taken out of the mold.

[0028] In order to facilitate the modification of the existing mouth mold, further as a preferred embodiment, the embodiment also includes a cylinder 400, the pin 200 is installed in the cylinder 400. For example, by processing a through hole (i.e. pin cavity) on the parting surface in the existing mouth mold, then the cylindrical cylinder 400 is fixed in the through hole. It can be understood that the cylinder 400 is provided with a mounting cavity 410 for the left and right movement of the pin 200, and the pin 200 is slidingly connected in the cylinder 400. The cylinder 400 not only provides the basis for the installation of the pin 200, but also protects the pin 200. As known, during the blowing process of the glass bottle, the glass liquid is in a high temperature state, that is, the mold in contact with the glass liquid will also be subjected to high temperature for a long time, if the pin 200 is directly in contact with the mold, the high temperature will be directly conducted to the pin, affecting the normal movement of the pin. By setting the cylinder 400 between the mold body 100 and the pin 200, the cylinder 400 is used to separate the pin 200 from the direct contact with the mold body 100, thereby protecting the pin 200. Preferably, the cylinder 400 can be made of a material with good heat insulation performance.

[0029] In use, first, the pin 200 and the elastic member 300 are installed in the cylinder 400, and then the cylinder 400 is installed in the mold body 100. In this way, the disassembly and assembly of the entire mouth mold can be more convenient.

[0030] Further, referring to Figure 3 , the front end of the mounting cavity 410 is provided with a limiting wall, the front end of the elastic member 300 abuts against the limiting wall, and the rear end of the elastic member 300 abuts against the pin 200.

[0031] Further, referring to Figure 3The pin 200 further comprises a boss 220, a shaped portion 230 located at the inner side of the pin 200, the boss 220 is located at the middle of the pin 200, and the driven portion 210 is located at the outer side of the pin 200. The front end and the middle of the pin 200 are arranged in the installation cavity 410, and the driven portion 210 is located at the outer side of the cylinder 400 and the mold body 100. The front side of the cylinder 400 is provided with a limiting hole, the inner diameter of the limiting hole is greater than the outer diameter of the shaped portion 230, but less than the outer diameter of the boss 220, the front end of the elastic member 300 abuts against the limiting wall of the limiting hole, and the rear end of the elastic member 300 abuts against the boss 220. The rear side of the cylinder 400 is further provided with a second limiting hole, the inner diameter of the second limiting hole is less than the outer diameter of the boss 220. Since the front and rear ends of the installation cavity 410 of the cylinder 400 are provided with limiting holes, and the boss 220 of the pin 200 is arranged in the installation cavity 410, when the pin 200 moves left and right, it is restricted by the two limiting holes respectively, thereby playing a role of restricting the moving range of the pin 200.

[0032] Further as a preferred implementation manner, the driven portion 210 protrudes out of the mold body 100, and the driven portion 210 comprises an arc surface. Generally, the force acting on the driven portion 210 is in the up-down direction, and the moving direction of the pin 200 is in the horizontal direction, so that the arc-shaped driven portion 210 can well decompose the force acting on the pin 200, and at the same time, the arc-shaped driven portion 210 can reduce the force bearing area of the driven portion 210, so that the movement of the pin 200 is more stable and smooth.

[0033] Further as a preferred implementation manner, the elastic member 300 is a compression spring, the elastic member 300 is sleeved on the outer side of the pin 200, one end of the elastic member 300 abuts against the inner wall of the cylinder 400, and the other end abuts against the boss 220. Further, the elastic member 300 is a high-temperature-resistant compression spring. Although the elastic member 300 is wrapped by the cylinder 400, the heat on the mold body 100 cannot be directly transmitted to the elastic member 300, but the working environment temperature of the elastic member 300 is still relatively high with the accumulation of time. Since the role of the elastic member 300 is very important, if the elastic member 300 cannot provide sufficient elastic force to reset the pin 200, the normal taking out of the product will be affected, especially after the glass bottle is formed, the outer wall of the glass bottle has certain viscosity with the shaped portion 230 of the pin 200, when the mold is opened, if the elastic member 300 cannot provide sufficient elastic force to separate the pin 200 from the glass bottle, the taking out of the glass bottle will be affected.

[0034] Further as the preferred implementation, the shaped part 230 of the pin 200 is in the shape of a circular truncated cone. The shape of the shaped part 230 directly determines the shape of the concave pit, and thus according to the design requirement, the shaped part 230 is in the shape of a circular truncated cone, which is convenient for the pin 200 to be separated from the glass product.

[0035] Further as the preferred implementation, a preliminary mold (not shown in the figure) is further included, an inner wall of the preliminary mold is provided with a protruding block, and the protruding block is connected with the driven part. When the mold is produced, the driven part is moved by the inner wall of the preliminary mold, so that the structure of the mold is simplified.

[0036] The preferred implementation of the present application is described above, but the present application is not limited to the above-mentioned embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. The equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
