Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1, a glass die convenient to replace is mainly composed of two parts: the outer mold 1 and the mold core 2, wherein the outer mold 1 is composed of a first half mold body 11 and a second half mold body 12, the first half mold body 11 and the second half mold body 12 are symmetrically arranged and are connected through concave-convex matching, an installation cavity is formed between the first half mold body 11 and the second half mold body 12, the mold core 2 is arranged in the installation cavity and is detachably connected with the outer mold 1, a cavity matched with the shape of a bottle opening is formed in the middle of the mold core 2, glass is molded through the mold core 2, and finally a glass bottle opening is formed.

Referring to fig. 1-3, the mold core 2 is formed by splicing a first mold half core 21 and a second mold half core 22, wherein the first mold half core 21 and the second mold half core 22 are symmetrically arranged and have identical shape and structure, a clamping part 201 is formed by protruding outwards in the circumferential direction of the first mold half core 21 and the second mold half core 22, and assembling grooves 101 matched with the clamping part 201 are formed at corresponding positions of the first mold half core 11 and the second mold half core 12, and the clamping parts 201 on the first mold half core 21 and the second mold half core 22 are respectively in concave-convex fit connection with the assembling grooves 101 on the first mold half core 11 and the second mold half core 12, so that the first mold half core 21 and the second mold half core 22 are installed.

As shown in fig. 4, in order to prevent the first mold half core 21 and the second mold half core 22 from falling off, screw holes 102 are formed at corresponding positions of two ends of the first mold half core 11 and the second mold half core 12 where the assembly grooves 101 are located, a screw 3 is disposed in each screw hole 102, as shown in fig. 5, two ends of a clamping portion 201 on the first mold half core 21 and the second mold half core 22 are recessed along the circumferential direction to form a step portion 202, after the first mold half core 21 and the second mold half core 22 are respectively clamped with the first mold half core 11 and the second mold half core 12, the screw is in threaded connection with the screw holes 102, and the screw 3 is screwed, so that a nut of the screw 3 is in close contact with the step portions 202 at two ends of the first mold half core 21 and the second mold half core 22, thereby fixing the first mold half core 21 and the second mold half core 22 on the first mold half core 11 and the second mold half core 12 respectively.

Therefore, the die core 2 is convenient to install and detach, and if the die core 2 with other types of bottle mouths is worn or needs to be replaced, the die core 2 is detached from the outer die 1, and a new die core 2 is replaced again for installation.
