Problems solved by technology

[0003] With these problems in mind, the production process of the product is analyzed, and the following conclusions are drawn. The shape of the product is slender, and in order to increase the feel of the handle, the round surface must have concave points, so in the production process, the product There will be problems such as out of round, burrs, shrinkage, and poor cooling effect of the mold, which will lead to problems such as inability to continue production

Embodiment 1

[0023] Such as Figure 1~Figure 2 As shown, a kind of injection mold for reducing deformation and uniformly cooling slender handles and its production process includes a moving mold, a first side slider forming mechanism 1, an oil cylinder core pulling mechanism 3 and a second side slider forming mechanism 4, and the moving mold is described. The first side slider forming mechanism 1 and the second side slider forming mechanism 4 are symmetrically installed on both sides of the mold, and the outer sides of the first side slider forming mechanism 1 and the second side slider forming mechanism 4 are respectively equipped with an oil cylinder core pulling mechanism 3 , the product 2 is installed on the movable mold between the first side slider forming mechanism 1 and the second side slider forming mechanism 4 .

[0024] A fixed mold is installed on the movable mold.

[0025] Said product 2 has at least 2 pieces.

[0026] The invention has a reasonable mold structure and a spec...

Abstract

The invention relates to a deformation reducing and uniformly cooling injection mold for long and thin handles and a production process. The mold comprises a movable mold, a first side slide block forming mechanism (1), oil cylinder core pulling mechanisms (3) and a second side slide block forming mechanism (4), and is characterized in that the first side slide block forming mechanism (1) and the second side slide block forming mechanism (4) are symmetrically arranged at two sides of the movable mold, the oil cylinder core pulling mechanisms (3) are arranged on respective outer sides of the first side slide block forming mechanism (1) and the second side slide block forming mechanism (4), and a product (2) is arranged between the first side slide block forming mechanism (1) and the second side slide block forming mechanism (4). The deformation reducing and uniformly cooling injection mold for the long and thin handles disclosed by the invention has a stable performance, a uniformly cooling system for movable and fixed molds reduces the forming cycle, the quality of the product can be better guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to an injection mold for reducing deformation and uniformly cooling a slender handle and a production process. Background technique [0002] In the production of daily necessities, the phenomenon of replacing steel with plastic is becoming more and more obvious. Due to the flexibility of plastic products, plastic products can form various and weird shapes of parts, which brings considerable challenges to the design and manufacture of plastic molds. Great challenge. At the same time, plastic products also need to take into account the functional requirements, such as tensile yield strength, elongation at break, bending strength, elastic modulus, impact strength, heat resistance temperature, heat distortion temperature, etc. must meet certain requirements; Some appearance requirements are also quite special, for example, some require high mirror surface, textured surface, ...
