Description

Bicycle rear upper fork mould

Technical Field

The utility model belongs to the field of carbon fiber molds, and particularly relates to a bicycle rear upper fork mold.

Background

The compression molding process of some carbon fiber raw materials is to adopt a shaping mold to press the rough shape of a finished product, and then to press and mold a semi-finished product through a carbon fiber mold.

When the existing partial carbon fiber mold is used for pressing a semi-finished product, supersaturated raw materials are required for pressing so as to avoid the occurrence of depression and the like on the product, but the finished product is easy to be pressed and solidified insufficiently and the product is relatively bloated.

SUMMERY OF THE UTILITY MODEL

The utility model provides a bicycle rear upper fork mould for solving the technical problems.

The solution adopted by the utility model for realizing the technical effect is as follows:

a bicycle rear upper fork mould comprises a mould body and a grease discharging pipeline; the die body comprises an upper die and a lower die; die cavities are formed in the bottom of the upper die and the top of the lower die; the die cavities of the upper die and the lower die are encircled to form a rear upper fork die cavity; the grease discharging pipeline is arranged on the lower die and positioned on two sides of the upper fork die cavity; the grease discharging pipeline is provided with a grease discharging hole which is communicated with the upper fork die cavity; and two ends of the grease discharging pipeline are communicated with the outside.

Preferably, at least two rear upper fork cavities are arranged between the upper die and the lower die side by side.

Preferably, four rear upper fork die cavities are arranged between the upper die and the lower die side by side.

Preferably, the upper die comprises a cleaning module and a pressing module; a water pipe is arranged in the cleaning module, and a jet orifice communicated with the water pipe is arranged at the bottom of the cleaning module; the pressing module is fixed at the bottom of the cleaning module through a bolt; the die cavity is arranged at the bottom of the pressing module; and a heating pipe is arranged in the lower die.

Preferably, a positioning groove is formed in the lower die; the bottom of the cleaning module is provided with a positioning column; the pressing module is provided with a positioning hole; the positioning column penetrates through the positioning hole and is inserted into the positioning groove in a sliding mode.

The beneficial effects of the utility model are as follows: the grease discharging pipeline is arranged, when the raw materials are extruded by the die to be molded, redundant raw materials can be extruded through the grease discharging pipeline, and air can be discharged along with the extrusion of the raw materials, so that a fastened and solidified high-quality product is pressed.

And (3) identification and explanation: 1-a grease discharging pipeline, 2-an upper die, 21-a cleaning module, 22-a pressing module, 3-a lower die, 31-a positioning groove, 4-a die groove, 5-a water pipe, 6-a jet orifice and 8-a positioning column.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model. It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When one element is referred to as being "fixedly connected" to another element, it may be fixedly connected by welding, bolting, gluing, or the like, as is commonly done.

Referring to fig. 1-3, in a preferred embodiment of the present invention, a bicycle rear upper fork mold is disclosed, which comprises a mold body and a grease discharging pipe 1; the die body comprises an upper die 2 and a lower die 3; the bottom of the upper die 2 and the top of the lower die 3 are both provided with a die cavity 4; the die cavities of the upper die 2 and the lower die 3 are encircled to form a rear upper fork die cavity; the grease discharging pipeline 1 is arranged on the lower die 3, and the grease discharging pipeline 1 is positioned on two sides of the upper fork die cavity; the grease discharging pipeline 1 is provided with a grease discharging hole which is communicated with the upper fork die cavity; and two ends of the grease discharging pipeline 1 are communicated with the outside.

Preferably, go up mould 2 with be provided with two at least between the lower mould 3 side by side the back is gone up the fork die cavity, specifically, go up mould 2 with be provided with four between the lower mould 3 side by side the back is gone up the fork die cavity, can produce four bicycle back and go up the fork in a suppression, improves production efficiency.

Specifically, the upper die 2 includes a cleaning module 21 and a pressing module 22; a water pipe 5 is arranged in the cleaning module 21, and a jet orifice 6 communicated with the water pipe 5 is arranged at the bottom of the cleaning module 21; the pressing module 22 is fixed at the bottom of the cleaning module 21 through bolts; the die cavity is arranged at the bottom of the pressing module 22; a heating pipe is arranged in the lower die 3.
