Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like figure 1 , figure 2 As shown, the structure of the upper mold 1 and the lower mold 3 is consistent, and they are respectively circular plates. The center of the upper mold 1 and the lower mold 3 is provided with a mandrel hole 5, and a stabilizing hole 4 is provided near the edge. The number of holes 4 is at least two, as shown in the figure, in this embodiment, two stabilizing holes 4 are respectively set on the upper mold 1 and the lower mold 3 .

[0016] like figure 1 , figure 2 As shown, the surface of the upper mold 1 and the surface of the lower mold 3 are respectively provided with inwardly recessed annular grooves 7 .

[0017] like image 3 As shown, the middle mold is composed of the left middle mold 2-1 and the right middle mold 2-2. The combination of the inner walls of the left middle mold 2-1 and the right middle mold 2-2...

Abstract

The invention relates to a mould structure. In order to solve the technical problem that a mould for manufacturing a rubber part provided with two flanges is low in efficiency at present, the invention provides a mould which is reasonable in structure and easy to take out a part. The mould comprises a round upper die, a round lower die and a round middle die, wherein the upper die is matched with the middle die and the middle die is matched with the lower die through conical surfaces so that the upper die and the middle die are superimposed together and the middle die and the lower die are superimposed together; a stabilizing mail hole is formed in each of the upper die and the lower die; the upper die is connected with the lower die through stabilizing nails; a mandrel hole is formed in each of the upper die and the lower die; a mandrel penetrates through the mandrel hole of the upper die, an inner cavity of the middle die and the mandrel hole of the lower die; and a rubber part die cavity is formed among the upper die, the middle die and the lower die. The mould is characterized in that the middle die is longitudinally divided into a left part and a right part, and the left part and the right part are locked through a clamping ring after being closed up. The mould is simple in structure and low in cost, and has very high production efficiency and practical efficiency.

Description

[0001] technical field [0002] The invention relates to a mold structure, in particular to a mold for making rubber parts with two flanges. Background technique [0003] In the motor production industry, it is often necessary to use a variety of rubber parts, such as rubber seals for sealing, rubber sleeves for incoming and outgoing lines, etc. The mold structure used in making these rubber parts not only determines the production efficiency, but also determines the quality of the parts. Take the commonly used rubber sleeve used for the inlet and outlet lines as an example. The rubber part is a cylinder, and a circle of notches is provided in the middle of the cylinder to be stuck on the body wall of the inlet and outlet parts. Therefore, the The rubber parts form the two flanges. The traditional mold used to make this part includes a lower mold, a middle mold, and an upper mold. The inner cavity of the middle mold forms a yin-yang combination with the surface of the part...
